ACKNOWLEDGMENTS
It seems as
though my book project has been in development for an eternity. Its completion had to
await (or did it cause?) certain powerful transformations in the universe, or
at least in my own bodymind. For all this, I am most grateful to God, who
manifested Herself in the form of devoted professional angels whose
participation was essential for bringing my book into the world.
I will be thankful
forever for the help of Susan Moldow,
whose enthusiasm and
brilliant vision provided constant inspiration and energized my effort; Nancy
Griffith Marriott, old friend, consciousness writer and consultant, who helped me set my thoughts
down in an understandable way; Beth Rashbaum, who pushed me to greater heights of clarity and cohesiveness;
Muriel Nellis, my fairy godmother, the best, most marvelous agent in the world;
Jane Roberts, for insightful, constant aid of all kinds; and Bernardo Issel,
for seminal library assistance and his angelic manifestations during times of
need.

Glossary
FOREWORD
I have admired
Candace Pert and her work for many years. In fact, I can remember the first
time I heard her speak and my delight at realizing: Finally, here is a Western
scientist who has done the work to explain the unity of matter and spirit, body
and soul!
In exploring how
the mind, spirit, and emotions are unified with the physical body in one intelligent system, what I call “the field of intelligence,” Candace has taken a giant step toward
shattering some cherished beliefs held sacred by Western scientists for more
than two centuries. Her pioneering research has demonstrated how our internal
chemicals, the neuropeptides and their receptors, are the actual biological underpinnings of our awareness,
manifesting themselves as our emotions, beliefs, and expectations, and
profoundly influencing how we respond to and experience our world.
Her research has
provided evidence of the biochemical basis for awareness and consciousness, validating what Eastern
philosophers, shamans, rishis, and alternative practitioners have known and
practiced for centuries. The body is not a mindless machine; the body and mind are one.
I have lectured
and written about the important role of perception and awareness in health and longevity—how awareness
can actually transform matter, create an entirely new
body. I also have said that the mind is nonlocal. Now Candace provides us with
a vivid scientific picture of these truths. She shows us that our biochemical messengers act with intelligence
by communicating information,
orchestrating a vast complex of conscious and unconscious activities at any one
moment. This information transfer takes place over a network linking all of our
systems and organs, engaging all of our molecules of emotion, as the means of communication. What we see is an image
of
a “mobile brain”—one that moves throughout our entire body, located in all
places at once and not just in the head. This bodywide information network is
ever changing and dynamic, infinitely flexible. It is one gigantic loop,
directing and admitting information simultaneously, intelligently guiding what
we call life.
There is a
revolution taking form that is significantly influencing how the Western
medical community views health and disease. Candace Pert’s contribution to this revolution is
undeniable; and her professional integrity in the pursuit of scientific truth,
wherever it had to take her, regardless of its personal or professional cost,
underscores the feminine, intuitive potential of science at its best.

1 THE RECEPTOR REVOLUTION: AN INTRODUCTORY LECTURE
SCIENTISTS,
by nature, are not creatures who commonly seek out or enjoy the public
spotlight. Our training predisposes us to avoid any kind of overt behavior that
might encourage two-way communication with the masses. Instead, we are content
to pursue our truth in windowless laboratories, accountable only to members of
our highly exclusive club. And although presenting papers at professional
meetings is encouraged, in fact required, it’s rare to find one of us holding
sway to standing-room-only crowds, laughing, telling jokes, and giving away
trade secrets.
Even though
I am a long-standing club member and bona fide insider myself, I cannot say that it has been my
trademark to follow the rules. Acting as if programmed by some errant gene, I
do what most scientists abhor: I seek to inform, to educate, and inspire all manner of people, from lay to professional. I try
to make available
and interpret the latest and most up-to-date knowledge that I and
my fellow scientists are discovering, information that is practical, that can
change people’s lives. In the process, I virtually cross over into another dimension, where the
leading edge of biomolecular medicine becomes accessible to anyone who wants to hear about it.
This mission
places me in the public spotlight quite often. A dozen times a year, I am
invited to address groups at various institutions, and so, when not engaged in
my work at Georgetown University School of Medicine, where I am a research professor
in the Department of Biophysics and Physiology, I go shuttling from coast to
coast, sometimes even crossing the great blue waters. It was never my plan to
become a scientific performer, to act as a mouthpiece for educating the public
as well as practitioners in the alternative health movement, so wed was I for most of my career to the
mainstream world of the lab and my research.
But it’s been a natural
evolution, and I am now at home in my new
role. The result of translating my scientific ideas into the vernacular seems
to have been that my life in science
and my personal life have transformed each other, so that I have become
expanded and enriched in myriad unexpected ways by the discoveries I’ve made,
the science I’ve done, and the meaning I continue to uncover.
Writing this book was an attempt to put down on paper, in a much more
detailed and usable form,
the material I’ve been presenting in lectures. My goal
in writing, as in speaking, was twofold: to explain the science underlying the new bodymind medicine, and to give enough practical
information about the implications of that science, and about the therapies and
practitioners embodying it, to enable
my readers to make the best possible choices about their personal health and
wellbeing. Perhaps my journey, intellectual as well as spiritual, can help other people on their paths. And
now—on with the “lecture”!
ARRIVAL
Whenever possible
I try to arrive at the lecture hall early, before the members of the audience
take their seats. I get a thrill out of sitting in the empty room, when all is quiet and there exists
a state of pure potentiality in which anything can happen. The sound of the
doors swinging open, the muffled voices of the crowd as they file slowly into
the room, the clinking of water glasses and screeching of chairs—all of this creates
a delightful cacophony, music to my ears, the overture for what is to
come.
I watch the
people as they move toward their seats, finding their places, chatting with a
neighbor, and getting comfortable, preparing themselves to be informed,
hopefully entertained, unaware that my goal is to do more: to reveal, to inspire, to uplift, perhaps even to
change lives.
“Who’s this
Candace Pert?” I may ask, retaining my anonymity as I playfully engage the
person now seated next to me. “Is she supposed to be any good?” The response is sometimes informative and always amusing,
allowing me a brief
entry into the thoughts and expectations of those I am about to address. I nod
knowingly in response and pretend to arrange myself more comfortably, more attentively.
I often find
myself addressing very mixed audiences. Depending on the nature of my host’s
organization, the crowd is either weighted toward mainstream
professionals—doctors, nurses, and scientific researchers—or toward alternative
practitioners—chiropractors, energy healers, massage therapists, and other
curious participants—but frequently includes members from both camps in a blend
that can best be described as the Establishment meets the New Paradigm. This
sort of composition is very different from the more homogeneous audiences present
at the hundreds of talks I’ve given over the past twenty-four years to my fellow
scientists, colleagues, and peers. For
them,
I deliver my more technical remarks in the language of the club, not needing to
translate the code we all understand. I still address such groups, making the
yearly round of scientific meetings, but now I also venture into a foreign
land, where few of my fellow scientists dare—or wish—to go.
Breathing deeply for a moment or two, I relax into my seat and close my
eyes. My mind clears as I offer a brief prayer to enter a more receptive state.
Calling on an intuitive sense of my audience’s expectations and mood, I can
feel the wall coming down, the imaginary wall that separates us, scientist from
lay person; the expert, the authority, from those who do not know—a wall I personally stopped believing in some time
ago.
THE AUDIENCE
As the room
fills, I can feel the excitement building. When I open my eyes and glance around at one of these mixed
crowds, I notice first that, in marked contrast to the more scientific
gatherings, there are usually large numbers of women present. It still
surprises me to see so many of them, dressed beautifully in their flowing California-style robes of many colors. I am
always stunned by the many shades of
purple in their dress, more shades than I ever knew existed! Then, looking
beyond the surface, I try to assess the various components of my audience and
what might have motivated them to come today.
My attention
goes first to the doctors and other medical professionals, whose contingent is
almost always dominated by males. The men sit erect in their well- tailored
dark suits and crisp white shirts, while nearby their female counterparts look officiously around, checking the room for the faces of their colleagues.
Scattered more sparsely throughout the room are the neophytes, earnest young men and women with packs on their backs and
dreams in their eyes. Their posture is perky and eager, revealing their
sincerity and also their uncertainty about
what they want or where they are going.
As the room
settles and voices are hushed to a low din, I wonder: What do all these people
expect me to tell them? What do they want to know, what are they hoping for?
Some are here
because they saw me on Bill Moyers’s PBS special Healing and the Mind, a program that also included segments with
Dean Ornish, Jon Kabat-Zinn, Naomi Remen,
and a number of the other doctors,
scientists, and
therapists
who are trying to make the same mind-body connections that have become my
life’s work. Being interviewed by such a well-informed, receptive journalist
made it possible for me to speak of the molecules of mind and emotion with a
passion and humor not ordinarily associated with medical research scientists. I
tried to make it easy for a television audience to understand the exciting
world of biomedicine, molecular theory, and psychoneuroimmunology, revealing information usually shrouded by an impenetrable language, letting them
know that they have a stake in understanding this body of knowledge, because it could give them the power to make a difference in the state of their own health.
The physicians,
nurses, health care professionals—what brings them out? Have they touched on
some new situation that their current knowledge cannot explain? Many of them
know me as a former chief of brain biochemistry who toiled at the National
Institutes of Health for thirteen years, demonstrating and mapping biochemicals
I later came to call the physiological correlates of emotion. Some may know
that I left the National Institutes of Health when I developed a powerful new
drug for the treatment of AIDS and couldn’t get the government interested. All
of them seem to be aware that science marches on, and that much of what they
were taught in medical school twenty years ago, even ten years ago, is no
longer current, even applicable. They know that my work is in a breaking
field—no less a chronicler of contemporary culture than Tom Wolfe himself has
pronounced neuroscience the “hottest field in the academic world” in a recent
issue of Forbes—and that it’s just
now finding its way into medical schools around the world.
Then there are the many massage
therapist, acupuncturists, chiropractors— the so-called alternative
medicine practitioners who offer their patients approaches that are not part of the mainstream. I’m aware that
these people have been marginalized for years, rarely taken seriously by the
powers that be—the medical schools, insurance companies, the American Medical
Association, the Food and Drug Administration—although it is well documented
that the public spends billions yearly on their services. Later, in the Q&A
sessions that follow the
talks, they tell me they believe I have done the research that will lead to the
validation of their theories, their beliefs. They have read about my theory of
emotions, about how I have postulated a biochemical link between the mind and
body, a new concept of the human organism as a communication network that
redefines health and disease, empowering individuals with new responsibility,
more control in their lives.
The
philosophers, the seekers, they’re here too. Some are very silent— listeners,
not talkers—these pale, earnest young men and women who tell me after the
lecture that they’ve been traveling in India or living in Asia. They see my
work as proof of what their gurus and masters have long been saying, and they
want more answers, perhaps about the meaning of it all. Maybe they’ve heard me
quoted as the scientist who said “God is a neuropeptide.” They know I’m not afraid
to use what most scientists consider a four-letter word—soul—in my talks, and they want me to address their spiritual
questions today.
Many come simply
because they are curious. Perhaps they’ve heard of my reputation as a young
graduate student who laid the foundation for the discovery of endorphins, the
body’s own pain suppressors and ecstasy inducers. Or they may know me as the young woman who was
passed over for a prestigious pre- Nobel Prize and dared to challenge her
mentor for the recognition she felt she deserved. They may recall how the
resulting front-page controversy exposed a system that was sexist and unjust at
its core, and caused a shake-up that embarrassed a medical dynasty.
Others are here
because they need to have hope. The sick, the wheelchair- bound, I see them
positioned on the aisles, near the doors. They know I’ve been on the cutting edge with my research,
crossing disciplines and researching for breakthroughs in cancer, AIDS,
mental illness. I always feel a little
nervous when I see them sitting in my audience. Are they expecting me to
deliver their miracle cure like a preacher at a revival meeting? Hope is a dirty, rarely uttered word in
the circles I frequent, and it still tugs uncomfortably at my self-image as a scientist. To think I’m being
viewed as a healer—God forbid,
a faith healer!
Yet
I can’t ignore the expressions of desperation and suffering that I see on their
faces. Information. Yes, at least I can give them that, something they can use
in seeking alternatives, these people for whom mainstream medicine offers no further answers, no treatment, no hope.
Regardless of
their profession, orientation, or expectations emotional or intellectual, I’ve
come to believe that most of the lay people who find their way to my lectures are hoping to hear science
demystified, de-jargonized, described in
terms they can understand. They want to be more in control of their own health and to learn more about what is
going on in their own bodies, and they have been deeply disappointed, disillusioned
by the failure of science to deliver on its promises to provide cures for the
major diseases. Now they want to take back some power into their own hands, and
they need to know about what the latest scientific discoveries mean for
obtaining optimal health.
Perhaps you, my
reader, see yourself in one or more of the groups described above. If so, I
hope for your sake, as I always hope for the members of my audiences, that some
part of the information presented in this book will make a difference in your
life.
TAKING THE STAGE
A sudden hush
descends on the room, catching me off guard, and my head turns as I glimpse a
figure walking slowly across the stage toward the spotlit podium. What follows
is generally a lavish detailing of my list of accomplishments. I feel genuinely
moved by the appreciation expressed by my host or hostess, but always a bit
embarrassed and undeserving of such flattering words.
Over the years,
I’ve learned to keep my ego reigned in by saying a quiet blessing during these
introductory remarks. I ask that I not be cowed by my mission, nor swept up in
it. I remind myself that, in spite of the spotlight I am about to step into,
first and always I am a scientist, a seeker of the truth—not a rock star! I
silently vow that I won’t let any of this go to my head—although that could
easily happen, and did happen occasionally at one time.
At last I hear my
name and rise from my chair to begin the long walk onto the stage. I remember to breathe deeply
as I pass the front row and feel all eyes in the room turn to focus on me. A few
whispered words reach my ears as I move along: “There she is! Is that her? She
doesn’t look like a scientist!”
What did they
expect? I wonder with an inward chuckle. I am still a woman, a wife, and a mother.
Don’t I fit their pictures
of the scientist? Of course,
they have their own ideas, and many of them fit the standard cliché of
the conservatively dressed,
intense-looking, usually male scientist. Not too long ago,
I wore those serious little boxy suits,
the dress-for-success uniform,
conforming to the more buttoned-down image people expect.
But now, my own
transformation is boldly reflected in the way I present
myself, an image that
better matches my message these days. In keeping with the evolution of my
scientific ideas, my dress has evolved so that I now look more like the ladies in
the flowing robes, my clothes looser and more colorful, more comfortable, even
more purple! These days I dare to be more outrageous, although those who know
me insist that outrageousness has always been the hallmark of my personality,
however submerged I’ve tried to keep it at times to survive.
Taking my place at the podium, I wait while the technicians fumble with my
mike
and make last-minute adjustments to the projection screen at my side. As I look out on the sea of upturned faces,
I am struck by how perfectly still people
sit. I know they won’t move until I crack a joke, giving them permission to
enjoy themselves and explode
in laughter, animating the room and filling it with
energy.
My audience is
ready and so am I—hundreds, sometimes thousands of people are seated before me
waiting for my words. I take one last minute to focus inwardly on my mission:
to tell the truth about the facts that were discovered by my colleagues and myself. First and foremost,
I am a truth-seeker. My intention
is to provide an understanding of the metaphors that express a new paradigm,
metaphors that capture how inextricably united the body and the mind really
are, and the role the emotions play in health and disease.
The house lights
dim as I clear my throat and my first slide comes up on the screen.
SETTING THE TONE
There is
something incredibly intoxicating about standing in front of a huge room full
of people who are all laughing uproariously. I have become quite addicted to
this experience, ever since 1977 when I gave a lecture to the National
Endocrine Society and accidentally brought down the house with a joke that was
intended to cover a mistake
I’d made. Now I don’t waste any time. I start right off
with a cartoon that never fails to elicit hearty, if sometimes
nervous, laughter.
My first slide looks like this:

I use this joke to
make the point that as a culture we are all in denial about the importance of
psychosomatic causes of illness. Break the word psychosomatic down into its parts, and it becomes psyche, meaning mind or soul, and soma, meaning body. Though the fact that
they are fused into one word suggests some kind of connection between the two,
that connection is anathema in much of our culture. For many of us, and certainly for most of the medical establishment,
bringing
the mind too close to the body threatens the legitimacy of any particular
illness, suggesting it may be imaginary, unreal, unscientific.
If psychological
contributions to physical health and disease are viewed with suspicion, the
suggestion that the soul—the literal translation of psyche—might matter is considered downright absurd. For now we are
getting into the mystical realm, where scientists have been officially forbidden
to tread ever since the seventeenth century. It was then that René Descartes,
the philosopher and founding father
of modern medicine,
was forced to make a turf deal with the Pope in order to get the human bodies
he needed for dissection. Descartes agreed he wouldn’t have anything to do with
the soul, the mind, or the emotions—those aspects of human experience under the
virtually exclusive jurisdiction of the church at the time—if he could claim
the physical realm as his own. Alas, this bargain set the tone and direction
for Western science
over the next two
centuries, dividing human experience into two distinct and separate spheres
that could never overlap, creating the unbalanced situation that is mainstream
science as we know it today.
But much of that
is now changing. A growing number of scientists recognize that we are in the
midst of a scientific revolution, a major paradigm shift with tremendous
implications for how we deal with health and disease. The Cartesian era, as
Western philosophical thought since Descartes has been known, has been
dominated by reductionist methodology, which attempts to understand life by
examining the tiniest pieces of it, and then extrapolating from those pieces to
overarching surmises about the whole. Reductionist Cartesian thought is now in
the process of adding something very new and exciting—and holistic.
As I’ve watched
as well as participated in this process, I’ve come to believe that virtually all illness, if not
psychosomatic in foundation, has a definite psychosomatic component. Recent
technological innovations have allowed us to examine the molecular basis of the
emotions, and to begin to understand how the molecules of our emotions share
intimate connections with, and are indeed inseparable from, our physiology. It
is the emotions, I have come to see, that link mind and body. This more
holistic approach complements the reductionist view, expanding it rather than
replacing it, and offers a new way to think about health and disease—not just
for us scientists, but for the lay person also.
In my talks, I
show how the molecules of emotion run every system in our body, and how this
communication system is in effect a demonstration of the bodymind’s
intelligence, an intelligence wise enough to seek wellness, and one that can potentially keep us healthy
and disease-free without
the modern high-
tech
medical intervention we now rely on. In this book I’ve tried to give pointers
about how to tap into that intelligence, and, in the Appendix, I’ve provided a
listing of organizations that practice various aspects of bodymind medicine, so that those of you who are interested can
get some guidance on getting the most out of that intelligence, allowing it to do its
job without interference. The Appendix also contains some basic tips for healthful
living, distilled from my own experience.
SHIFT
HAPPENS! The Ptolemaic earth at the center of the universe can give way to the Copernican sun-centered theory—but
not without considerable resistance. Witness Galileo, who was brought before
the Inquisition for his role in promulgating that theory over a century after
it was first proposed! Or ask Jesse Roth, who in the 1980s found insulin not
just in the brain but in tiny one-celled animals outside the human body. This gave the reigning medical
paradigm a good shake,
because everyone “knew” that you needed a pancreas to make insulin! In spite of
his eminence as clinical director for the National Institutes of Health, Dr.
Roth couldn’t get his papers published in a single reputable scientific journal
for quite a while. The reviewers sent them back with comments such as: “This is
preposterous, you must not be washing your test tubes well enough.” Jesse retaliated by using new test tubes
and repeating his results often enough so that other researchers, intrigued by
his findings, began doing similar experiments and reporting similar results.
Jesse’s story
illustrates one of the paradoxes of scientific progress: Truly original,
boundary-breaking ideas are rarely welcomed at first, no matter who proposes them.
Protecting the prevailing paradigm, science moves slowly, because it doesn’t
want to make mistakes. Consequently, genuinely new and important ideas are
often subjected to nitpickingly intense scrutiny, if not outright rejection and revulsion, and getting them
published becomes a Sisyphean
labor. But if the ideas are correct, eventually they will prevail. It may take,
as in the case of the new discipline of psychoneuroimmunology, a good decade,
or it may take much longer. But, eventually, the new view becomes the status
quo, and ideas that were rejected as madness will appear in the popular press,
often touted by the very critics who did so much to impede their acceptance.
Which is what is happening today as a new paradigm comes into being.
And not a moment
too soon as far as the holistic/alternative health crowd is concerned. They’ve
been disgusted with the reigning medical model for years and have, in fact,
been working actively to overturn it. It’s largely through their efforts that such formerly
dismissed techniques as acupuncture and hypnosis
have
gained the credibility they now have. But even when I talk with the average
health-conscious consumer, people who have no ideological animus one way or the other, I’m always astonished at how
deep their anger at our present health system is. It’s obvious the public is
catching on to the fact that they’re the ones paying monstrous health care
bills for often worthless procedures to remedy conditions that could have been
prevented in the first place.
IN ORDER
TO grasp the enormity of this revolution, you have to first
understand some of the fundamentals of biomolecular medicine, which is what I
like to explain at the beginning of my talks. How many of us can close our eyes
and picture or define a receptor, or a protein, or a peptide? These are the
basic components that make up our bodies and minds, yet to the average person,
they are as exotic and remote from everyday experience as the Abominable Snowman. If we’re to understand
what role our emotions may play in our health, then understanding the molecular-cellular domain is a crucial first step. I also
like to provide some historical context to help people understand the impact of the recent discoveries. It’s a version
of one of those lectures I’m putting on the page here to provide
a broad overview of my work, the basic science
that makes it all
decipherable, and fun.
But I also have
a story to tell, one that is more personal than scientific, even though parts
of it do make their way into some of my more informal public lectures. The narrative of how I was transformed by the science
I did, and how the science
I did was inspired and influenced by my growth as a human being, especially by
my experience as a woman, is as informative, I believe, as the facts of my scientific
adventure’s, and equally as important. For this reason, I have included my
personal narrative in this book, sandwiched in between sections of my lecture, where
I hope it provides a perspective that enlightens as it reveals the human story behind the molecules of emotion. As befitting my own
evolution, the personal and the scientific do eventually intertwine as my story
progresses, underscoring the fact that science is a very human pursuit and
cannot be truly appreciated if it appears as a cold and emotionless
abstraction. Emotions affect how we do science as well as how we stay healthy
or become ill.
THE BASICS
And now on with the science!
The first component of the molecules
of emotion is a molecule found on the
surface
of cells in body and brain called the opiate
receptor. It was my discovery of the opiate receptor that launched my
career as a bench scientist in the early 1970s, when I found a way to measure it and thereby prove its
existence.
Measurement! It
is the very foundation of the modern scientific method, the means by which the
material world is admitted into existence. Unless we can measure something,
science won’t concede it exists, which is why science refuses to deal with such “nonthings” as the emotions, the mind,
the soul, or the spirit.
But what is this
former nonthing known as a receptor? At the time I was getting started, a
receptor was mostly an idea, a hypothetical site believed to be located
somewhere in the cells of all living things. The scientists who most needed to
believe in it were the pharmacologists (those who study and invent drugs)
because it was the only way they knew to explain the action of drugs in the
organism. Dating back to the early-twentieth century, pharmacologists believed
that for drugs to act in the body they must first attach themselves to
something in it. The term receptor was
used to refer to this hypothetical body component, which allowed the drug to
attach itself and thereby in some mysterious way to initiate a cascade of
physiological changes. “No drug acts unless it is fixed,” said Paul Ehrlich,
the first modern pharmacologist, summarizing what he believed to be true, even
though he had no real evidence. (Only he said it in Latin to emphasize the
profundity of the concept.)
Now we know
that that component, the receptor, is a single molecule, perhaps the most
elegant, rare, and complicated kind of molecule there is. A molecule is the tiniest possible piece of a substance that can still be
identified as that substance. Each
and every molecule of any given substance is composed of the smallest units of
matter—atoms such as carbon and hydrogen and nitrogen— which are bonded together
in a configuration specific to that substance, which can be expressed as a chemical formula, or, more
informatively, drawn as a diagram.
Invisible forces
attract one molecule to another, so that the molecules cohere into an
identifiable substance. These invisible forces of attraction can be overcome if enough
energy is applied to the substance. For example, heat energy will melt ice crystals, turning them into water, which will then vaporize into steam as its molecules
move so fast, with so much energy,
that they break loose
of each other and fly apart. But the chemical formula remains the same for each
state—in this case H2O, two hydrogen atoms bonded to one oxygen atom— whether
that state is an icy solid, a watery liquid, or a colorless vapor.

In contrast to
the small, rigid water molecule, which weighs only 18 units in molecular
weight, the larger receptor molecule weighs upwards of 50,000 units. Unlike the
frozen water molecules that melt or turn into a gas when energy is applied, the
more flexible receptor molecules respond to energy and chemical cues vibrating. They
wiggle, shimmy, and even hum as they bend and change from one shape
to another, often moving back forth between
two or three flavored shapes, or conformations. In the organism
they are always
found attached to a cell, floating
on the cell surface’s oily outer boundary
or membrane. Think of them as lily pads floating on the surface of a
pond, and, like lilies, receptors have roots enmeshed in the fluid membrane
snaking back and forth across it
several times and reaching deep into the interior of the cell.
The receptors
are molecules, as I have said, and are made up of proteins, tiny amino acids
strung together in crumpled chains, looking something like beaded necklaces
that have folded in on themselves. If you were to assign a different color to
each of the receptors that scientists have identified, the average cell surface would appear as a multicolored mosaic of at least seventy
different hues
—50,000
of one type of receptor, 10,000 of another, 100,000 of a third, and so forth. A
typical neuron (nerve cell) may have millions of receptors on its surface.
Molecular biologists can isolate these receptors, determine
their molecular weight, and eventually crack their chemical
structure, which means identifying
the exact sequence of amino acids that makes up the receptor
molecule. Using the
biomolecular techniques available today, scientists are able to isolate and
sequence scores of new receptors, meaning that their complete chemical structure can now be diagrammed.
Basically,
receptors function as sensing molecules—scanners. Just as our eyes, ears, nose,
tongue, fingers, and skin act as sense organs, so, too, do the receptors, only
on a cellular level. They hover in the membranes of your cells, dancing and
vibrating, waiting to pick up messages carried by other vibrating little
creatures, also made out of amino acids, which come cruising along
—diffusing is the technical word—through
the fluids surrounding each cell. We like to describe
these receptors as “keyholes,” although
that is not an altogether
precise
term for something that is constantly moving, dancing in a rhythmic, vibratory
way.
All receptors
are proteins, as I have said. And they cluster in the cellular membrane waiting
for the right chemical keys to swim up to them through the extracellular fluid
and to mount them by fitting into their keyholes—a process known as binding.
Binding. It’s sex on a molecular
level!
And what is this
chemical key that docks onto the receptor and causes it to dance and sway? The
responsible element is called a ligand.
This is the chemical key that binds to the receptor, entering it like a key in
a keyhole, creating a disturbance to tickle the molecule
into rearranging itself,
changing its shape until
—click!—information enters the cell.

THE TIES THAT BIND
If receptors are
the first components of the molecules of emotion, then ligands are the second. The word ligand comes
from the Latin ligare,
“that which binds,” sharing
its origin with the word religion.
Ligand is the term used for any natural
or manmade substance that binds selectively to its own specific receptor on the
surface of a cell. The ligand bumps onto the receptor and slips off, bumps back
on, slips back off again. The ligand bumping on is what we call the binding, and in the process, the ligand
transfers a message via its molecular properties to the receptor.
Though a key
fitting into a lock is the standard image, a more dynamic description of this process
might be two voices—ligand and receptor—striking
the same note and producing
a vibration that rings a doorbell to open the doorway to the cell. What happens next
is quite amazing. The receptor, having received a message, transmits it from
the surface of the cell deep into the cell’s interior, where the message can
change the state of the cell dramatically. A chain reaction of biochemical
events is initiated as tiny machines roar into action and, directed by the
message of the ligand, begin any number of activities—
manufacturing
new proteins, making decisions about cell division, opening or closing on
channels, adding or subtracting energetic chemical groups like the
phosphates—to name just a few. In short, the life of the cell, what it is up to
at any moment, is determined by which receptors are on its surface, and whether
those receptors are occupied by ligands or not. On a more global scale, these
minute physiological phenomena at the cellular level can translate to large
changes in behavior, physical activity, even mood.
And how is all
this activity organized, considering it is going on in all parts of the body
and brain simultaneously? As the ligands drift by in the stream of fluid
surrounding every cell,
only those ligands
that have molecules
in exactly the right shape can bind to a particular kind of receptor. The
process of binding is very
selective, very specific! In fact, we can say that binding occurs as a result
of receptor specificity, meaning the
receptor ignores all but the particular ligand
that’s made to fit it. The opiate receptor, for instance, can “receive”
only those ligands that are members of the opiate group, like endorphins,
morphine, or heroin. The Valium receptor
can attach only to Valium
and Valium-like peptides. It
is this specificity of the receptors that allows for a complex system of
organization and insures
that everything gets to where it’s supposed
to be going.
Ligands are
generally much smaller molecules than the receptors they bind to, and they are
divided into three chemical types. The first type of ligand comprises the
classical neurotransmitters, which
are small molecules with such unwieldy names as acetylcholine, norepinephrine,
dopamine, histamine, glycine, GABA, and serotonin. These are the smallest, simplest
of molecules, generally made in the brain to carry
information across the gap, or synapse, between
one neuron and the next. Many start out as simple
amino acids, the building blocks
of protein, and then get a few atoms added here and there. A few
neurotransmitters are unmodified amino acids.
A second
category of ligands is made up of steroids,
which include the sex hormones testosterone, progesterone, and estrogen. All
steroids start out as cholesterol, which gets transformed by a series of
biochemical steps into a specific kind of hormone. For example, enzymes in the
gonads—the testes for males, the ovaries for females—change the cholesterol
into the sex hormones, while other enzymes convert cholesterol into other kinds
of steroid hormones, such as cortisol, which are secreted by the outer layer of
the adrenal glands under stress.
I’ve saved the
best for last! My favorite category of ligands by far, and the largest, constituting perhaps 95 percent of them all, are the peptides. As we shall
see,
these chemicals play a wide role in regulating practically all life processes,
and are indeed the other half of the equation of what I call the molecules of
emotion. Like receptors, peptides are made up of strings of amino acids, but
I’m going to save the details about peptides until a later point in my lecture.
Meanwhile,
one way to keep all this in your mind is to visualize the following: If the
cell is the engine that drives all life, then the receptors are the buttons on
the control panel of that engine, and a specific peptide (or other kind of
ligand) is the finger that pushes that button and gets things started.

THE CHEMICAL BRAIN
At this point,
I’d like to move away from the purely molecular level, and, with our new
knowledge of the receptor and its ligands, focus for a moment on how scientists
now view the brain, and how that view differs from our earlier, more limited
understanding.
For decades,
most people thought of the brain and its extension the central nervous system
primarily as an electrical communication system. It was common knowledge that the neurons, or
nerve cells, which consist of a cell body with a tail-like axon and treelike
dendrites, form something resembling a telephone
system with trillions of miles of intricately crisscrossing wiring.
The dominance of
this image in the public mind was due to the fact that we scientists had tools
that allowed us to see and study the electrical brain. Only recently did we
develop tools that allowed us to observe what we may now call the chemical
brain.
But,
yet-to-be-named neuroscience was so
focused, for so long, on the concept of the nervous system as an electrical
network based on neuronaxon- dendrite-neurotransmitter connections, that even
when we had the evidence, it was hard to grasp the idea that the
ligand-receptor system represented a second nervous system, one that operated
on a much longer time scale, over much greater distances. The nerves were the classical subject of
neuroscience, the
route
science had taken in its first explorations of the brain and central nervous
system, so it was only with some disgruntlement that people could contemplate
the idea of a second nervous system. Especially difficult to accept was that
this chemical-based system was one indisputably more ancient and far more basic
to the organism. There were peptides such as endorphins, for instance, being
made inside cells long before there were dendrites, axons, or even neurons—in
fact, before there were brains.
Until the brain
peptides were brought into focus by the discoveries of the 1970s, most of our attention had been
directed toward neurotransmitters and the jump they made from one neuron to
another, across the little moat known as the synaptic cleft. The neurotransmitters seemed to carry very basic
messages, either “on” or “off,” referring to whether the receiving cell
discharges electricity or not. The peptides, on the other hand, while they
sometimes act like neurotransmitters, swimming across the synaptic cleft, are
much more likely to move through extracellular space, swept along in the blood
and cerebrospinal fluid, traveling long
distances and causing complex and fundamental changes in the cells whose
receptors they lock onto.
This, then, was as much as we understood about the receptor
and its ligands by 1972, before researchers had actually found a drug
receptor, and well before the
breakthrough involving the immune system in 1984. which used receptor theory to define a bodywide network
of information and to provide
a biochemical basis for the emotions. In the wake of discoveries in the 1980s, these receptors and their ligands
have come to be seen as “information molecules”—the basic units of a language
used by cells throughout the organism to
communicate across systems such as the endocrine, neurological,
gastrointestinal, and even the immune system. Overall, the musical hum of the
receptors as they bind to their many ligands, often in the far-flung parts of
the organism, creates an integration of structure and function that allows the organism to run smoothly,
intelligently. But I’m getting way ahead of my story. Let’s take a break from
the science and look at how some of these ideas developed historically.
A BRIEF HISTORY
OF RECEPTORS
While the idea
of the receptor mechanism had originated with pharmacologists in the early twentieth century, many university physiology
departments
took it up as well because they found it a useful concept to explain the new
chemical substances being found in the nervous system—the neurotransmitters.
These chemical communicators, which were secreted across the synapse, or gap
between neurons, also functioned in a way that could be understood by the
receptor-ligand model, even though biochemistry had yet to develop a way to
measure what was happening.
The chemical
formula of acetylcholine, the first neurotransmitter to be discovered, was
still decades away from being diagrammed when physiologist Otto Loewi did his
early neurotransmitter experiments following a dream he had one night! These
first experiments, performed in 1921, involved the action of a neurotransmitter
on a frog heart. Removed from the frog and placed still beating in a large beaker, the heart slowed down
dramatically when Loewi applied juice extracted from the vagal nerve to it. The mysterious “vagusstuff” turned out to be the neurotransmitter acetylcholine. Made by the nerves,
acetylcholine causes a slowing of the heartbeat and a rhythmic stimulation of the digestive muscle after eating, which together contribute to
the feeling of relaxation. For both of these
processes, scientists theorized
that there were acetylcholine “receptor sites,” some on the heart
muscles, others on the digestive tract muscles, and still others on voluntary skeletal
muscles, but they couldn’t actually
demonstrate their existence.
Early
twentieth-century theory became reality in 1972, when Jean-Pierre Changeux
addressed a pharmacology conference in England. With a dramatic flourish, the
biochemist pulled from his breast pocket a tiny glass tube with a single narrow
blue band across its middle. The tube contained pure acetylcholine receptors
taken from the body of an electric eel and separated from all the other eel molecules and stained blue. This was the first time a receptor had been isolated in the lab.
Changeux
explained how the feat had been made possible by an unholy alliance between a
cobra and an electric eel, with the former supplying the venom to isolate the receptors from the latter. In higher
animals, the cobra’s venom acts by entering a victim’s body and diffusing to
the acetylcholine receptors, including those on the diaphragm muscles, which
regulate breathing. The venom blocks the access of natural acetylcholine to its
receptors. Since acetylcholine is the neurotransmitter that’s responsible for
muscle contraction, the resulting paralysis
of the diaphragm muscles causes death by suffocation.
Now, it just so
happens that the densest concentration of acetylcholine receptors to be found
anywhere is in the electric organ of the electric eel. Scientists had found that
snake venom contained a large
polypeptide, called
alpha-bungero
toxin, that bound specifically and irreversibly to the acetylcholine receptors
in this organ that supplies the eel’s jolt. It literally stuck like glue. By
introducing radioactive atoms to the toxin in the snake’s venom, Changeux could
follow it to where it stuck to the acetylcholine receptors of the eel’s electric organ, and thereby isolate those
receptors. That is how he had obtained the blue- stained substance in his test
tube. The process of making a ligand hot, or radioactive, by introducing radioactive atoms into it was a brilliant innovation, but it was—and still is—a very
tricky procedure, because the radioactive substance can destroy the ligand’s ability to
bind, thereby defeating the whole point
of the process.
Another major
stream that had contributed to “receptorology,” as we jokingly dubbed the
emerging field, was the discipline of endocrinology, the study of ductless
glands and their secretions. Endocrinologists, like the pharmacologists and
physiologists before them, needed a way to explain how the chemical substances
known us hormones acted at a distance from their sites of release on their
targeted organs. But in those days—we’re talking the 1950s and 1960s—it wasn’t
very likely that an endocrinologist would be found talking to a pharmacologist.
Each field of study occupied its own little niche and was separated from the others by strictly
drawn boundaries that defined the disciplines. Those working within a given discipline were
generally unaware of and uninterested in what their fellow scientists were
doing elsewhere. So people in each
field kept making parallel discoveries without understanding what these
discoveries had in common.
In the 1960s, endocrinologist Robert Jensen had been able to use a
microscope to see estrogen receptors that had bound with radioactive estrogen
he’d injected into female animals. As predicted, the radioactive estrogen went
to receptors in breast, uterine, and ovarian tissue—all the known target organs
for this female hormone. Later, estrogen receptors, as well as receptors for
testosterone and progesterone, were unexpectedly found in another organ, the
brain, with amazing consequences
for sexual identity. But that’s a
later part of our story.
In 1970,
endocrinologists Jesse Roth and Pedro Cuatrecasas, working on separate teams at
the National Institutes of Health, were able to measure the insulin receptor by
following Changeux’s approach of rendering their ligand— insulin—radioactive.
Before, Cuatrecasas had been able to get close enough to show that insulin
receptors were located on the outside surface of cells. But the new techniques
for labeling substances with radioactive atoms were among the
key
advances that allowed for the actual measurement of the receptor, a tremendous
breakthrough in this field.
A NEW IDEA
My own work in
“receptorology” began in 1970, in the halls of the pharmacology department of
Johns Hopkins University, where I was able to earn my doctoral degree studying
under two of the worlds experts on insulin receptors and brain biochemistry. At
that time, the insulin receptor was the only receptor being studied
with the new methods that had been developed for trapping the more slippery ligands, that is, those
that, unlike the snake toxin when it bound to the acetylcholine receptor, did
not stay irreversibly stuck to its receptors. No one had tried the new methods
on any other drugs. But there was clearly a need to study other receptors to try to trap other kinds of ligands.
In my own
field, for example the prevailing dogma was, as I mentioned earlier, that no drug
could act unless fixed. This presented an interesting challenge to neuropharmacology, the
particular area of pharmacology in which I had become interested, because,
theoretically, it meant that if a drug worked,
there had to be a receptor, and our job should be to find it. The drugs
we were studying at the time were drugs that obviously changed behavior—I
almost said consciousness, but back then nobody used the C-word, except the
hippies, Yet everyone recognized that these drugs, which included
heroin, marijuana, Librium,
and PCP (“angel dust”), precipitated a radical change in the emotional state,
that is, altered the state of consciousness of those who used them. That’s why,
when I began my career in the early 1970s, such drugs were our main tool for
studying the chemistry of the brain.
The problem was
that our drugs were all from plants, and it was well known that once in the
body these plant-derived ligands bound to receptors so briefly before exiting
the body in the urine that they were difficult, if not impossible, to catch and
measure on their receptors.
The challenge I
would eventually make my own was to use the new methodology to trap the small morphine molecule on its receptor in a test tube— a
receptor that many people didn’t even believe existed. The proof that it did
would have ramifications beyond my wildest dreams. In completely unexpected
ways, the discovery of the opiate receptor would extend into every field of
medicine, uniting endocrinology, neurophysiology, and immunology, and
fueling
a synthesis of behavior, psychology, and biology. It was a discovery that
touched off a revolution, a revolution that had been quietly under way for some
time—about which more will be revealed in the future lecture sections in this
book. But now my own story must begin.
One warm summer afternoon, shortly after I had been
accepted into graduate school at Johns Hopkins University, I was packing for
the move to Edgewood, Maryland,where I would live with my husband. Agu Pert,
and our small son, Evan. As the material objects of domestic life—the dishes,
the clothes, the iron I’d used to iron Agu’s white shirts—began to disappear into
boxes, I became aware of a growing
sense of panic.
By the time Agu came home, I was immobilized, slumped in
a chair and fighting back tears.
“What’s with you?” he asked, not taking much notice of my disturbed state. Always the calm and
steady one, he said nonchalantly, “It looks like you got a lot done.”
“I know,” I responded, trying to rally myself. “But
graduate school … graduate school … it’s an hour away. How will I ever…” I
trailed off, overwhelmed by the thought of the challenges that lay ahead
of me. How would I balance the chores
of my role as wife and mother with the demands of earning a Ph.D. degree,
commuting daily to Baltimore, and working full- time in a laboratory? I
gestured pathetically at the boxes on the floor.
“Don’t worry,” Agu declared. “I’ll
do it all! I’ll do the cooking, the cleaning, I’ll make sure Evan gets to day care.
Your job is to
concentrate on going to school and learning psychopharmacology.”
And that’s exactly what I did.
2
ROMANCE OF THE OPIATE RECEPTOR
DESTINY
Looking back over twenty-five years, it seems
that destiny played
an important role in the unfolding of events that led to the discovery
of the elusive opiate receptor. Although it was my fierce belief and passionate
devotion that drove me in the final stages. I had only my curiosity and a
series of seemingly serendipitous occurrences to put me on the track of proving
that there did indeed exist within the brain a chemical mechanism that enabled
drugs to act.
My first
encounter with the opiate receptor was in the summer of 1970, after I’d
graduated with a degree in biology from Bryn Mawr College and before I entered
medical graduate school at Johns Hopkins University in the fall. That encounter was personal, not professional. In June I had accompanied my husband and small son to San Antonio, Texas, where we were to
live for eight weeks while Agu completed his required medical corps basic
training for the army. Agu had completed his Ph.D. in psychology at Bryn Mawr,
and now it was time to fulfill his deferred
military obligation. I was looking forward to a summer off, maybe even a
vacation, after four years of grueling, married-with- child college life. I
also intended to bone up on some basics before entering the doctoral program in
the fall, so I brought with me a copy of Principles
of Drug Action by Avram Goldstein. Since the program I was entering at
Hopkins would focus on neuropharmacology, the study of the action of drugs in
the brain, I wanted to prepare myself and figured Goldstein’s
book was the best place to start.
But real-life
experience preempted the academic learning, and instead of reading about the
opiate receptor, I got to experience its effects firsthand. A horseback-riding
accident put me flat on my back in a hospital bed, where, doped to the gills on
Talwin, a morphine derivative I was given to ease the pain of a compressed
lumbar vertebra, I remained for most of the summer. My body immobilized by the
injury and my attention span shanghaied by the drug, I was unable to
concentrate enough to read the selected text or any other book, and instead spent my
days lying around in a
blissful altered state while my back
healed.
Later, when I
was off the drug and able to sit up, I read part of Goldstein’s book, which included a thorough
introduction to the concept of the opiate receptor. I remember
marveling at how there were tiny molecules on my cells that allowed for that wonderful
feeling I’d experienced every time the nurse had injected me with an
intramuscular dose of morphine. There was no doubt that the drug’s action in my
body produced a distinctly euphoric effect, one that filled me with a bliss
bordering on ecstasy, in addition to relieving all pain. The marvelous part was
that the drug also seemed to completely obliterate any anxiety or emotional discomfort
I had as a result of being confined to a hospital bed and separated from my
husband and young child. Under its influence, I’d felt deeply nourished and satisfied, as if there
weren’t a thing in the world I wanted. In fact,
I liked the drug so much that, as I was ending my stay at the hospital, I very briefly toyed with the idea of stealing some to take with me. I can see how people become addicts!
This intense
overlap of physical and emotional experience, both originating from a single drug, fascinated me and sparked
anew my interest in the connection between brain and
behavior, mind and body—a connection that had originally come to my attention
during my freshman year in college. On my own for the first time in my life, I
had subsisted for an entire semester on a diet of peach pie, and thereby had thrown myself
into both a thyroid blowout
and a major depression. So it
happened that I received my official introduction to the idea that something
happening in the body could affect the emotions. Now, as I began graduate
school, I was about to explore the connection scientifically, and begin the
work to which I would eventually devote my life. And it all had to do with
these strange little things called opiate receptors.
THAT FALL,
at the age of twenty-four, I officially entered Johns Hopkins University
Medical School as a doctoral candidate in the department of pharmacology.
Unofficially, it was the beginning of my apprenticeship in neuroscience, a discipline that did not yet exist, and would not for almost a year.
I didn’t know it then, but I had walked right into the center of a revolution
that was brewing, one in which the
boundaries of distinct disciplines such as biochemistry, pharmacology,
neuroanatomy, and psychology would dissolve to make way for the new
interdisciplinary field of neuroscience.
I remember the
first morning I arrived and parked behind the old Johns Hopkins medical
laboratory building. I was literally trembling as I got out of my car, painfully aware that with the exception of a couple
of high school
science-
fair
projects and a borderline senior science project in college, I’d never
performed a real experiment. As an undergraduate biology student, I had been
incapable of bringing myself to kill and dissect an animal. But that was strictly
my own shortcoming, not that of my education, which was excellent.
At Bryn Mawr, my
early science training had been in the classroom of a Miss Oppenheimer, a fine
teacher who almost threw me out of the department because of my stubborn,
albeit principled refusal to kill a frog for dissection. There was some emotion
in me that would not allow me to kill an animal. The thought of pulling apart a
creature that I myself had just killed, no matter how marvelous its structure
or incredible its fluids, made me sick to my stomach.
“Don’t be
squeamish!” Miss Oppenheimer exclaimed. “How can you ever expect to study the
brain if you don’t get over this? You’ve got to put this nonsense behind you if
you ever want to do great work.”
Miss Oppenheimer
had become my role model, my heroine, and I would have done almost anything to
please her, because she had actually taken me seriously when I told her of my
interest in the crossover between physiology and psychology, but this I couldn’t do. Only much later, after I became sensitive to the complex sexual politics of science,
did I understand her vehemence on the subject. Miss Oppenheimer had been
trained in another era, when the belief that women couldn’t do good science
prevailed. Women who survived did so by becoming hard and cold on the surface, adopting
a persona I later came to refer to as the “science nun.” I’d see
them at meetings, these severe and often brilliant women, wearing
all-black clothing, their
hair pulled back and tightly
knotted.
They were rarely married
and had no children, as it their female natures
had been obliterated by their need to prove they were just as strong,
just as exacting, and just as relentless as the guys.
Already married
and a mother at twenty, I had two strikes against me as a novitiate to this particular order. In addition,
my display of female
squeamishness over spilling
blood was almost too much for my teacher to stand.
I know that Miss Oppenheimer spent more than a few distraught moments weighing
my obvious devotion and creative gifts against her better instincts, which told her I would have no future in
science. Somehow, she let me slip through, and while I was grateful for the
leeway, I knew I’d never be able to fall back on this bit of female maneuvering
once I got to the big leagues—especially if
I wanted the guys to take me seriously, which I did.
All this flashed
through my mind as I stood at the entrance of the Hopkins medical building,
trembling and literally
unable to move, feeling like a complete
fraud,
although ecstatically anxious at the same time. A fraud, yes, but a sincere and
eager fraud, one who was willing to do whatever needed to be done, to learn
whatever was required! What kept me from running back to the car and driving
away that morning, I don’t know. The only thing I knew for certain was that, in
spite of my near-total lack of experience, I was there because I wanted to be.
And
the tug of fate was undeniable—everything had unfolded magically to bring me to
this point where I now stood.
Geography had
limited my choice of graduate schools to two, Johns Hopkins and the University of Delaware, both within
commuting distance from
Edgewood Arsenal in Edgewood, Maryland,
where Agu would be stationed.
Agu
was completing his military requirement in the experimental psychology
laboratory, planting tiny tubes in monkey brains to locate the centers of
pleasure and pain. We lived on the base, a long but not impossible drive from
downtown Baltimore, where Hopkins, my first choice, was located. Even though I
had a small child at the time, there had never been any question but that I
would continue my education
uninterrupted while Agu finished his stint in the army.
We
were a scientific team, Agu and I, a blend of his knowledge of the behavioral
sciences with my blossoming expertise in biology. Together, we expected to do
great science.
At the entrance
interview I’d had the winter before at Hopkins, the man who interviewed me was obviously
amazed that a wife and mother, especially the wife of a soldier who might be called at any moment to the
jungles of Vietnam, was seriously seeking entrance to one of the country’s
finest graduate schools to study biomedicine. I wasn’t too surprised a month
later when I received a letter from the medical schools biology department
rejecting my application.
Delaware’s
biology department had accepted me, and so I decided that was the end of it,
that’s where I would go. But fate intervened, and before my first fees came due
for admission to Delaware, something happened that changed the course of my
life forever, putting me on a trajectory headed straight into the center of the
neuroscientific revolution.
Fate’s opening
gambit occurred in the spring, when I attended my first scientific meeting, the
annual Federation of American Societies of Experimental Biology Conference in
Atlantic City, New Jersey, a gathering attended by some 20,000 biologists from
all over the world. During a break in the presentations, I found myself at the
edge of a small circle formed around a scientific publisher who was gossiping about
a new researcher at Johns Hopkins, a neuropharmacologist and psychiatrist by
the name of Dr. Sol Snyder. This unusual combination of specialties caught my attention. Here was someone,
this
Dr.
Snyder, who was studying the chemistry of the brain while at the same time
bringing to it a knowledge and understanding of human behavior. I remember
thinking, “That’s exactly what I want to do!” But, unfortunately, I’d been
accepted by Delaware, not Hopkins.
Fate was not
going to abandon my cause, however. When I returned home to Bryn Mawr after the
conference, Agu and I went to a lecture sponsored by the psychology department
featuring Dr. Joe Brady, a psychologist from the medical school of Johns
Hopkins who’d done pioneering mind-body studies on monkeys, linking the stress of having no control
over a situation with the development of severe ulcers. After the lecture, we
attended the departmental party, where Brady showed himself to be a real Gene Kelly
on the dance floor. At one point
he called out, “Anybody here know the Peabody?”
As it happened,
I had learned the fast-moving 1930s dance from my Estonian in-laws during
the many Brooklyn
basement parties I’d attended while
engaged to Agu, so I took up the challenge. We Peabodied like champs for
the next hour before collapsing in a sweaty heap, kicking a lamp over on our
way down. Later, over drinks, we made small talk, and he asked me what my goals
were for after college.
“I want to study
the brain.” I told him. “because I’m interested in understanding behavior from
the angle of biology.” Joe Brady nodded attentively and then said, “Well, then,
the guy for you is Sol Snyder, someone new at Hopkins medical school, a real
wild man doing just that. Send me something about yourself, and I’ll see that
Sol gets it.”
Ignoring the fact that one department at Hopkins had already turned me
down, I wrote a long letter telling Joe my fondest dreams and desires, and I
included a transcript of my courses and grades. Within a short time, I got a
phone call from the wild man himself.
“You’re accepted,”
Dr. Snyder said in a friendly, crisp tone. “Now apply.”
And that’s how it all began, a
series of events that unfolded almost according to some predestined script, bringing
me to Sol and to the
tiny lab in the west wing of
the Hopkins medical building, which was nestled in the slums of downtown
Baltimore.
ENCHANTMENT
Hopkins offered a Ph.D. program through
its pharmacology department that
was
research-oriented rather than academic. There were plenty of lectures,
readings, and coursework, but the heart of the program was the labwork. Each
student was expected to apprentice under four different scientists, rotating in
and out of their labs every two months. It was made very clear that the
successful completion of the program depended on performance in the lab.
Home base for me
was Dr. Snyder’s lab, where I began my training in lab technique and performed
my first experiment. Consisting of only three benches crammed into a single
room, the lab was but a dim foreshadowing of its future self. But to me it was
heavenly. The centrifuges hummed and the radioactive counter clicked, while
handsome postdocs scurried hither and yon, cracking sophisticated jokes and
performing highly technical maneuvers at their benches. The realization that I
had landed in a lab that was pushing the frontier of brain research, exploring
the biological basis for mental illness, was almost too exciting for me to bear.
Solomon H. Snyder, I quickly came to see, more than lived up to his wild-
man reputation. At thirty-four, he was already at the top of the profession, an
acknowledged prodigy who was routinely described by his colleagues as brilliant
and ambitious. He had been trained as a psychiatrist, but had apprenticed in
neuropharmacology at the National Institutes of Health, studying the effects of
drugs on the brain. There he had acquired an appetite and a skill for
experimentation that led him to persuade Hopkins to give him both a private
practice and a lab. Sol became the youngest full professor in the history of Hopkins
when he was only thirty-one. His dual appointment in pharmacology and psychiatry positioned him on both sides of the mental health
front, giving him a uniquely
well-balanced, comprehensive perspective. He treated patients with the current mind
drugs and monitored their effects, while a few paces down the hall, he directed
research in the lab for the next generation of medicine in mental health.
At first, I wondered
why Dr. Snyder rarely appeared in the lab. He preferred.
I found out, to do his science from the “throne
room,” which was how his students referred to his office. The
room was huge and immaculate, with an oversized desk at one end and a leather
couch at the other. A genuine Kandinsky dominated one wall, while Sol’s awards and prizes
were prominently displayed on another: the Outstanding
Young Scientist award from the Maryland Academy of Sciences, the John Jacob Abel Award, and many others.
Sol’s desk was always in perfect order, belying the
volume of paperwork he did, enough to keep three full-time secretaries busy.
They sat in the outer office, cranking out grant proposals and handling the
constantly ringing phones.
At the time of
my arrival, the focus in the lab was on
identifying new chemical
neurotransmitters—those “juices” secreted in the brain that were thought to carry information and direct
the activities of the organism. Jumping the synapse between brain cells, the
neurotransmitters bind to receptors on other brain cells, or neurons, causing
an electrical charge that redirects the neural pathways. The effect on the organism
is to change the physical
activity, including behavior and even mood—the closest
word to emotion in the lexicon of hard science.
Sol had
developed a method for determining which substances were neurotransmitters and
which were not. This involved measuring the “re-uptake” mechanism, a cellular
operation that insured that the excess juices left over after binding would be
sucked back into the neuron and destroyed. If the substance under investigation
was found in the brain, and its re-uptake could be measured, then we bad a
neurotransmitter. Before Sol’s method had been developed, only two
neurotransmitters were well studied and understood—acetylcholine and
norepinephrine (which is also called noradrenaline). But by the time I joined
the lab, Sol and other neuroscientists were in the process of adding five more:
dopamine, histamine, glycine, GABA, and serotonin.
Sol knew that
the work being done in his lab was at the center of a revolution, and communicating this to his students was part of his charisma. He had a way
of letting us know we were on the cutting
edge, caught up in a grand and glorious gamble, which, if we won, would make us all stars. Yet at the same
time we knew we were in about the most secure spot any apprentice scientist could ever ask for.
Sol, I
discovered, was one of the Golden Boys of the medical establishment— well
connected and well funded. While we were gathering data down in the scientific
trenches, Sol was out in front, jetting around the country and the world to explore the furthest frontier. He’d fly
in from Zurich or Palm Springs and the next day round us all up for a report on
the latest and hottest news from labs around
the globe: who was working on what, and what was breaking next where. We loved
it and hung on his every word.
Unlike most
scientists, who move forward slowly with tiny baby steps, afraid of taking any
real risks, Sol liked to think big and bold. He had a profound disregard
bordering on arrogance for the tedious side of science, directing only those
experiments that were both very simple and focused on the really big questions.
He displayed absolutely no respect for boundaries, tramping his way onto the
highly protected turfs of other researchers to satisfy his huge
interdisciplinary
intellect. His specialty was spotting projects that showed promise for an
imminent breakthrough, research where maybe nine-tenths of the work had been
done, and all that was missing was a bold formulation, a risky adjustment.
“Let’s take advantage of this situation,” he would cry. “Bang! Let’s get on it!
Let’s beat them to the prize!”
Sol saw science
as a game, and took every advantage to win. A master at motivating us, he awed us with the way he commanded
his resources and people.
I was so inspired by his tactics,
his charisma, and his brilliance that I was eager
to do anything, including work all night or arrive in the lab at some ungodly
hour in the early morning to take a
time point on an experiment. I lived to please him and bring him good data.
If we saw Sol as
just short of God, he in turn worshiped his mentor, Dr. Julius Axelrod, one of
the founders of the field of neuropharmacology and an omnipresent force behind the scenes. At the National
Institutes of Health,
Sol had come up the ranks through Julie’s lab, and he was one of
“Julie’s boys,” a group of scientists who had learned a research style from
their mentor that would lay the foundation of modern neuropharmacology. JULIE’S
BOYS SKIM THE CREAM had been written
on the wall of the lab years ago, to describe their
hugely effective approach to research. And Julie’s boys formed a scientific
dynasty, sharing information and using their influence to support each other at
funding time, often rotating favored students and postdocs through each other’s
labs in a giant game of chess.
When Julie won the Nobel
Prize in medicine shortly after I arrived at
Hopkins for his work with noradrenaline, one of the nervous system’s two principal neurotransmitters, the news electrified our lab.
We
all felt forever blessed, securely positioned in a line of succession that was
part of Julie’s patrimony.
The blessing
extended far beyond
giving us access to information and funding. At the heart of this chain of brilliant and
aggressive minds was a philosophy, one that I came to understand in terms of
the following dictums: Do not accept the conventional wisdom. Do not accept the
idea that something can’t be accomplished because
the scientific literature says it can’t. Trust
your instincts. Allow yourself a wide
latitude in your speculations. Don’t depend on the literature—it could be right or it could be
completely wrong. Spread all your hunches out before you, and go with the ones
that you think are most probable. Select the one that you can test easily and
quickly. Don’t assume it has to be overly complicated to be of value, since often the simplest experiment
yields the
most
unequivocal result. Just do the experiment! And if you can keep it to a one-
day experiment, so much the better.
This was our
inheritance, handed down from Julie Axelrod to his disciples, including Sol,
and then from Sol on to me. Eventually, I would pass it on to my students, and
they to theirs, in an unbroken chain of methodology and philosophy that I’m sure will continue holding
sway long after we’re all gone.
INITIATION
With a generous
wave of his hand, Sol showed me where I would be working, assigning me to a lab bench,
a chest-high slab of marble
with drawers below
it and shelves above.
“Now go find Ken Taylor,”
Sol ordered me in his best
fatherly tone. “He’ll show you how to do the histamine assay.”
The assay is a
procedure that is at the foundation of experimental research. It provides us
scientists with a method for measuring the quantity of a chemical substance,
such as a neurotransmitter, in a series of samples such as tissue or blood. The
point is measurement! Before you can ask any serious questions, you have to be
able to give a numerical value to the chemicals in each of your samples, a number that corresponds to high
or low concentrations of the substance you are studying.
Ken, it turns
out, was incredibly handsome, a New Zealander who regularly organized the
department’s pub parties on Friday afternoons. He was also a very focused
researcher and rigorous in his instruction. His presence at my lab bench was absolutely erotic, a fact that increased my desire to be the best at whatever
he instructed me to do. But I kept my feelings hidden and carefully avoided any
female maneuvering. I’d been well indoctrinated with an almost religious approach to science by Miss Oppenheimer at
Bryn Mawr, and even though I’d balked at her approach, I wasn’t going to take
any chances and risk being dismissed
as a less than serious student here at Hopkins. Instead, my attitude was one of
a novitiate in the Church of Science being taught her first catechism by a
virile young priest. Later, when I had my own lab, I would see the potential
for combined male-female energy as a positive force to do great science.
Over the course
of the next few weeks, Ken filled me in on the basics. Histamine is a chemical
normally secreted by cells of the immune system, causing allergic reactions
such as sneezing and itching (which is why we take antihistamines to relieve
allergy symptoms). Contrary to conventional wisdom, Ken and Sol had recently found histamine in the brain, a find that had led them
to
speculate on the possibility that histamine could be a neurotransmitter, one more of the brain’s information-carrying
messenger chemicals that they’d been identifying. Even at this point, I knew
that research on neurotransmitters was the hottest thing going, and I was
ecstatic to be included in any part of it.
Soon I fell into a daily routine. My first job every morning
was to number fifty test tubes and place them on a rack. After I’d done that, I would get the day’s brain tissue samples from Ken
and distribute them evenly among the numbered
test tubes. Then the fun began. Using
a thin, delicate, hand-blown
glass straw called a pipette, I carefully transferred tiny amounts of various
substances into the test tubes, the first of about ten steps that would turn
each test tube into a numerical result by the end of the day.
I learned later
that the histamine assay I was doing was based on Sol’s own early work.
Devising a method of carrying out the measurement, which he had done while
working with Julie Axelrod, was Sol’s first major accomplishment in the lab,
and this method now served as a link in the process to determine if histamine
was a neurotransmitter.
What we were
doing with the histamine assay is an example of the way that most biomedical
research unfolds. First, a technique is discovered that provides answers to
questions that have previously been unanswerable. Then we deploy that new
technique to the nth degree, putting to it every possible question that might
apply or be of further research value, until we’ve exhausted the
possibilities—or until some newer technique comes along to make the previous
one obsolete.
I loved sitting at my lab bench, day in and day out, pipetting my chemicals
and wearing my crisp, white lab coat. (It’s only in Hollywood movies that
scientists wear white lab coats. In real life, the novices, not the real
scientists, are the ones who wear
them.) I loved it so much that
it wasn’t unusual for me to spend ten hours or more in the lab at a stretch. The atmosphere was charged,
often very intense, which made for a special feeling of aliveness. I thrived on
the incessant conversations about everything from science to art to politics.
I soon became
aware of an unspoken but formal hierarchy in the lab. Rank, it seemed, was a
matter of longevity. Those who were there the longest generally had the most power—unless you were a
woman. (In that case—and a rare case it was, since there weren’t many women in
important labs like Sol’s—you were seen
not as a wise senior but as an old shoe, comfortable, nonthreatening, reliable.) Advancement was the result of higher-ups leaving
to embark on careers of their own, allowing the now-seasoned novitiates to occupy their slots.
But
this wasn’t always the case. Doing “hot science” brings its rewards. Any kind of major discovery can zoom an
underling straight to the top of the heap— something I was to find out
firsthand in the not-too-distant future.
After a few
months of practice at the histamine assay, when my data was crystalline and my
technique well honed, I was summoned before a panel of senior scientists in the
program. Their goal was to grill me mercilessly on every aspect of the
histamine assay in order to determine if I was worthy to pass on to the next
stage of the program. Even though I had prepared thoroughly, I was so nervous
under their cold and unfriendly scrutiny that suddenly I couldn’t remember
anything.
In short order,
my inquisitors demolished what little knowledge I had, while seeming to relish
every minute of my ordeal. As I realized later, it was a ritual to them, like a
fraternity hazing, putting young scientists in their place, reminding them they
really didn’t know much yet.
Sometime after
enduring this unsettling little game, I was told, to my great relief, that I had passed the review and was now permitted to enter the next
stage, selecting an original research project for my Ph.D. dissertation. I was
well aware that there was no hope of
my ever becoming a real scientist without a Ph.D. Those who stopped short and stayed
at the M.A. level were forever relegated to the bench, seldom acknowledged on
scientific papers, regardless of how much they contributed. But once I had a
Ph.D., which had been my plan from the start, I’d be in the club, and all I needed
for admission was to turn out
an original piece of research, one good enough for publication in a reputable
scientific journal.
After conferring
with Sol, it was decided that I should work on the choline re- uptake mechanism
for my Ph.D. dissertation. One of Sol’s postdocs, Hank Yamamura, had already
used Sol’s formula to measure choline re-uptake in the brain. Now Sol assigned
me to follow up on his findings by measuring it in the ileum of a guinea pig
(research that was related to work being done at a lab in Scotland, where they
were investigating the role of various neurochemicals binding to as-yet-unidentified receptors on cell surfaces in the
guinea pig ileum, causing muscle contraction).
The ileum, the
upper part of the small intestine, contains the cholinergic nerve that releases
the neurotransmitter acetylcholine. Here was another opportunity to be part of the neurotransmitter research
I’d been so excited about when I’d first arrived, but my enthusiasm was
noticeably flat. I couldn’t help but think it was dull and derivative, a kind of hand-me-down project with a
fairly predictable outcome, one that did nothing to inspire or excite my
imagination.
Putting my
distaste aside, I threw myself into the work. This was my first time preparing
a scientific experiment from scratch, depending only on a few earlier reports,
and after several tries. I had it up and running. I remember thinking about Dr.
Frankenstein as I organized the procedure, first removing a section of the
guinea pig’s gut, then squirting buffer through it to act as an enema. After
that, I dissected it to the muscle, which was heavily lined with nerves. I then
minced the muscle into neuron-containing fragments and placed them in beakers,
adding a radioactive form of choline. The “hot” choline acted as a trace to
give a signal that could be measured easily, showing that it was quickly taken
up by the neurons in the nerve-containing muscle and converted into the
neurotransmitter acetylcholine.
The choline assay
was a meat-and-potatoes kind of project, a sure bet to an easy Ph.D., and one
for which any sensible doctoral candidate would have been grateful. For weeks I
toiled away at it, but remained profoundly unmoved in the process.
• • •
WHILE I WAS still in the set-up stages of the hated choline project.
I came across a flyer posted on the department bulletin board announcing a
lecture by a Dr. Pedro Cuatrecasas, an endocrinologist and newly appointed
professor of pharmacology at Hopkins. The lecture was being offered as part of
a department series and served as a way for the highly renowned researcher from
the National Institutes of Health to introduce himself and his work to the
Hopkins faculty and student body.
“If anyone
around here ever wins the Nobel Prize,” Sol had told me, “It’s going to be
Pedro!”
I marked my
calendar and began to make some inquiries about the upcoming lecture.
Dr. Cuatrecasas,
I found out, had been part of one of the NIH teams that was the first to
isolate and measure a receptor on the surface of a cell wall—the receptor for
the hormone insulin. As explained earlier, the ability to actually measure a
receptor meant that one of the biggest mysteries of modern medicine had been
solved. Central to his method was the Multiple Manifold Machine, a device that
had been built for Marshall Nirenberg to use in the experiments he had done a few years
before at the NIH when he was trying to crack the DNA amino acid code. The Triple M, as I came to call it, had revolutionized filtration,
a
process that allowed for the rapid separation of bound from unbound ligands,
making it possible to measure receptor-specific binding. In his lecture it was
expected that Dr. Cuatrecasas would be showing how he and his team had used
this device to discover the insulin receptor.
The day of the lecture, I arrived early and stood in the lobby of the lecture hall with the waiting crowd. Sol
was unable to attend himself, but had urged me
to go and insisted I give him a full report when I returned. The
excitement in the air was almost palpable, not the usual prelude to a
department lecture, and I remember feeling a sense of anticipation that what
we’d be hearing would be far from the usual
stuff. This was about science
that was newly breaking, the leading edge! When the doors opened, I
entered and hurried to a seat in the front row.
Inside, the room
was buzzing. At the podium stood the lecturer, not a particularly commanding figure but nonetheless an attractive and intense man, his Latin heritage visible in the sparkle
of dark eyes and, as he talked, in his expressive enthusiasm for his subject.
All eyes in the room followed him closely as he paced back and forth, showing graph after graph,
curve after curve, proving beyond a doubt that he had
indeed discovered a method to measure insulin as it bound to specific receptors on fat cells
as well as to receptors
on cells in the liver, mediating the entry and storage of sugar in these
cells. As his remarks came to a close, he looked directly at me, pausing
for a moment to flash a stunning smile as our eyes met.
Did he know I was Sol’s graduate student and that Sol had sent me to check him
out? I couldn’t tell for sure, but I decided there on the spot that he was
someone I wanted to work with. As soon as I got back to Sol’s lab, I put in a
request to be rotated into Dr. Cuatrecasas’s lab as part of the requirements
for my course of studies.
A few days after the lecture, Sol and his wife invited Agu and me to a
small dinner party at their home, where the only other guests were Pedro
Cuatrecasas and his wife. I was thrilled and felt very privileged that Sol had
included me in such an intimate gathering—me, a lowly graduate student!
It was at that dinner that I first
experienced the powerful
and romantic allure of doing great science.
As I listened to their conversation, I felt that nothing
could compare to learning and working in the company of men such as these. I was thrilled by all of it, the gossip, the
politics, the breakthroughs, even the sense of competition with other labs. I
loved it all, though in my naivete I really knew very little about it.
It was also at this dinner that I was nudged farther along the path that would
lead me to my life’s work.
This happened during
the course of a conversation that began when Sol politely
asked Agu and me about life in the army. Agu had started military life as a
captain, having been a reservist during college and graduate school,
and because he had more seniority than his colleagues, he was at the time
running the psychology lab at Edgewood Arsenal. The talk turned to our experience at boot camp in Texas,
where, I explained, I’d spent three weeks flat on my back in the base hospital,
pumped full of opiate-derived morphine and feeling no pain. I mentioned that
I’d brought with me a copy of Avram Goldstein’s Principles
of Drug Action, which I’d repeatedly tried
to read while in
the hospital, never getting any further
than the section on opiate
receptors.
It was
fortuitous that I had mentioned Goldstein’s book and my experience of being medicated
with morphine in the same breath, for it reminded
Sol of his own interest in the subject
of the opiate receptor. In fact, during
the same summer I spent lying
on my back, Sol had been a participant at the Gordon Conference, an exclusive,
prestigious scientific gathering. Avram Goldstein himself was one of the
presenters, and at the conference, he outlined a plan for how he intended to discover the opiate
receptor in the brain. Sol was skeptical about
the technique Goldstein
proposed to use, which seemed crude and probably not up to the job of
isolating a reliable signal out of the thousands of chemicals that occupy any
single drop of neurojuice. But he was interested in the project itself.
After the conference, Sol had looked
up some of Goldstein’s
papers and brought them back to his office, intending to study them further.
“The opiate
receptor?” I asked Sol the next day in his office, as he handed me one of
Goldstein’s papers on the subject.
“Yes, it’s just like the insulin receptor—only it’s for morphine,” Sol replied.
An intriguing discussion followed
in which I learned that finding receptors in the brain was expected to be many
times more difficult than locating them in the rest of the body. At the time of
our discussion, only one receptor for a known neurochemical had ever been
found. In the experiment I described earlier in my lecture, the Frenchman
Jean-Pierre Changeux had just recently isolated and measured the receptor for acetylcholine in the electric organ of an electric eel.
But
this was considered a special case. Fully 20 percent of the electric organ of
this species of eel consisted of acetylcholine receptors, a huge target
compared to the one-millionth of a
percent of the brain that the opiate receptor was estimated to be. What made
the search for an opiate receptor even more problematic, as Sol had said, was
that while receptors had been located for chemicals that originated inside the
body (endogenous), like insulin and
acetylcholine,
no one had ever found a receptor that fit drugs that originated outside of the body (exogenous), opiates
like morphine, heroin,
or marijuana.
As I listened, I
was remembering my ordeal at the army hospital and the blissful state of consciousness I’d experienced every time I got
an injection of painkilling morphine. The opiate receptor! Now here was a goal
I could easily imagine pursuing, a project worthy of my dreams, my ambitions,
my aspirations. To take part in unraveling the mystery of how the opiates worked
to produce their magical,
otherworldly effects—what could be more exciting? To find a receptor for morphine, the drug over which wars had been fought, kingdoms lost, the mystical substance that
suffused the writings of Coleridge and DeQuincey and was part of the revolution in
sensibility wrought by the great nineteenth-century romantics Byron, Shelly,
Keats, and Wordsworth. Morphine was named in honor of Morpheus, the god of
dreams in Greek mythology, and it was a drug that I knew firsthand, a drug that
had fascinated me by its effects on mind and body.
I decided that
night I would ask Sol to let me switch projects and leave the choline re-uptake
assay behind and begin a search for the opiate receptor. I knew he believed
that finding the opiate receptor
was a near-impossibility, and I figured it wasn’t likely to be
something he’d even think of assigning to a Ph.D. candidate. But I didn’t care.
His skepticism only added to the glamour, enhanced the appeal. And, besides, it
would be an original project—not a hand-me-down based on someone else’s
research, something he knew I found tedious. I remember feeling inspired
and thinking, from my somewhat
limited perspective at the
time, that if I succeeded, then I just might become famous—as a graduate
student who had actually done an exciting and original piece of work for her
doctoral dissertation.
When I approached Sol, he was ambivalent.
“It’s a long
shot.” he warned me. “The choline study is a bread-and-butter project, easily
achievable,” Sol insisted. “Are you sure you want to take the chance when
you’ve got a sure thing?”
“Absolutely,” I replied.
“Well, read
over Goldstein’s paper and think about how you would approach the project,” he
told me.
As I read over
the paper and reflected on its contents, a single thought stood out in my mind: What could Goldstein have done if he’d had Pedro’s Triple M?
THRESHOLD
It was 1972, and
the Nixon administration had just begun an all-out war on drugs. Heroin and
heroin addicts were to be a focus of Nixon’s campaign, and the administration announced it was
allocating over six million dollars for addiction research. There was a lot of
talk in the media about the possibility of creating a“magic bullet,” a new drug
to cure heroin addiction, but in the lab, we knew that all this talk was just
that—we didn’t have a clue how opiates and heroin worked on the brain. Sol had
already set his focus on amphetamine research, and he’d written a grant and
submitted it to the newly established National Institute of Drug Abuse. With
Sol’s history of successfully obtaining money
for his projects, there was no doubt he’d get funded for this
one.
As researchers on the breaking
edge of neuroscience, we knew that all the talk
about coming up with new drugs in the struggle
against addiction didn’t make sense. How could we come up
with a drug to fight drug addiction when the mechanism for how opiates
like heroin and morphine operated
in people was still so far from being understood?
For any real breakthroughs to occur in the battle against
addiction, a logical
first step would
be to find the opiate
receptor.
And
so Sol, part of whose brilliance lay in combining great leaps of the
imagination with equal doses of conservative science, added a very brief
appendix to his amphetamine proposal, requesting funds to support research
aimed at finding the opiate receptor.
While Sol waited
for the bureaucracy to give us the green light, I headed off to Pedro’s lab for
a two-month rotation. My mission was to get some firsthand knowledge of the
Triple M and how Pedro had used it to understand and measure the insulin receptor.
Pedro’s
laboratory pulsated around the clock. I loved the graceful but exhilarating
rhythm, a samba compared to the rock-and-roll pace I was used to in Sol’s lab. But in the back of my mind, I stayed focused
on my goal, which was to practice and hone my skills in
preparation for my soon-to-begin pursuit of the opiate receptor.
Pedro himself
kept fairly regular hours in order to be with his family at dinnertime, but his students and postdocs stayed late into the night, often hovering over their work until the
first signs of light. In the lab, Pedro would
make his appearance with the flourish of a showman. Unlike Sol, who was usually busy with
equally important matters elsewhere, Pedro enjoyed appearing right when the most critical step of an experiment was about to be performed,
giving it his special spin, and demonstrating his techniques to us in the process.
The bulk of
the lab’s activity centered on Pedro’s efforts to expand his earlier work with
the insulin receptor. With the team that had made the discovery now disbanded,
there was a wild race going on for what in science are called the“follow-up
discoveries.” Since he was one of the original group, Pedro was able to command generous amounts of
funding as well as personnel in the high- stakes race against the competition.
As can be expected with most scientific achievements, a dispute arose over who
was actually responsible for the successful
discovery of the insulin receptor, and who would earn the prizes that would
ultimately follow. At Hopkins, the rumor was that Pedro was responsible for the
bulk of the work, and that it was his ability to make pure, active, radioactive insulin
that enabled the group to eventually prove the existence
of the insulin receptor.
Before getting
started on the Triple M, Pedro wanted me to tie up loose ends on an experiment he’d begun shortly
before leaving the NIH to come to Hopkins. With Nobel laureate Chris
Anfinson, he’d created something called an “affinity column,” a piece of
state-of-the-art technology for purifying molecules, which used the natural
affinity of one molecule for another to purify enzymes from solution. He’d put me to work using this technique to try
to isolate an important enzyme. Living things use hundreds of enzymes, which
are protein catalysts that efficiently perform in seconds chemical reactions
that would take weeks in a test tube—if they could happen at all.
For weeks I
was the darling of Pedro’s lab, loading the cellular soup into the glass column
and successfully building up the supply of enzymes in a pure form. Midway through
the process, however,
Pedro got news that a rival lab had
beaten us to the punch. They’d completed the purification while we were still
toiling away. One morning he came into the lab, slapped a paper down on my bench, and exited without
saying a word. I read the document
and, in my naivete, thought—Great!
Our work is confirmed. But as far as Pedro was concerned, all that mattered
was that a rival lab had beaten us to the punch. The experiment was over. We had been scooped, and since Pedro
was not interested in follow-up work, I was taken
off the project, pronto. Looking back, I see that this incident was my first close-up glimpse of the gamesmanship
that goes on in the big leagues, where winning is everything.
I consoled
myself by learning how to measure insulin receptors with the help of the Triple
M. Every day I’d pour my cellular concoction, a mixture that contained radioactive insulin and liver cell
membranes, through the filtering
mechanism.
The radioactive insulin acted like a ligand, first binding to its receptor, then slipping off, then rebinding
and rereleasing. As long
as the receptor stayed in a wet state, this activity would continue
without stopping. We were looking for a way to rapidly
dry the organic material and trap the ligand in a bound state, while the unbound
substances were washed away.
Pedro’s Triple M
provided state-of-the-art rapid filtration. With the Triple M, numerous test
tubes could he dumped onto the filtering mechanism one by one. The cellular
soup would be sucked away with a strange whhhhoooosssshhhhkkk
sound, leaving only the bound material stuck onto the receptor. The Triple M had worked perfectly on the insulin
receptor, but would it help us find the opiate receptor?
As a result of
Sol’s connections, as well as his sterling reputation, the grants committee
gave us the money for the opiate research, but they were skeptical of our chances.
Along with their approval for the funding,
the committee sent a
letter covering themselves should we fall flat on our faces, as they obviously
expected we would. As far as they were concerned, our chances were slim to none. Indeed, if anyone other than Sol
Snyder had had the audacity to submit the proposal, it surely would have been rejected, never to have seen the light of day.
EXPERIMENT
An experiment is
divided into two parts: first the design, then the implementation. But rarely
do they follow one another smoothly.
My experimental
design was planned with Pedro’s insulin receptor work in mind, borrowing
especially from the rapid filtration technique I’d learned on his Triple M. At
the same time, I was mindful of the work Avram Goldstein was doing. In the
paper Sol had given me, Goldstein described his attempts to isolate the opiate
receptor with a method that involved pulverizing mouse brains into a solution
and adding radioactive opiates. The batter was then spun very fast in a
centrifuge, causing cell nuclei and nerve endings to separate out at different speeds.
It was obvious
to both Sol and me that the technique Goldstein used could not work for a
number of reasons. As indicated by the handwritten notes he had scrawled all over Goldstein’s paper. Sol believed
that one of Goldstein’s
problems was that the radioactive tag on his binding substance hadn’t been hot
enough. He deduced this because
although a signal had been found, it wasn’t
very clear or distinct. So in our experiment, we decided to zero in on only one
opiate,
morphine, and to make sure that we got it to the point where it was as hot as the
existing technology allowed—a big challenge. Today there are catalogs from which you can order any number of already-purified radioactive opiates, but back then we had to ship the “cold” morphine to a
special lab to get it tagged with radioactive isotopes. When we got it back, we
had to put it through a purification process to separate out any possible
contaminants. This was a
crucial step, since if our hot morphine was contaminated, it wouldn’t give off
a signal clear enough to be picked up by the counter.
While Goldstein
hadn’t been able to get his experiment to work, he did have a clever idea that
we would find useful in implementing our own
experiment.
Since the morphine in his soup could bind indiscriminately to anything, he needed a way to show it was binding to an opiate receptor and not to some artifact, that is, to something that had been created in the artificial environment of the test tube. To do this, he used a
stereoisomer, a synthetic opiate designed specifically in a laboratory and
having two mirror-image forms. Both forms have the same chemical structure, but the left-handed version, called levorphanol, is an extremely potent opiate, while the right-handed version,
called dextrophan, is almost inert.
Goldstein tagged
the two forms of the opiate with a radioactive trace and mixed each one into a
test tube containing his cellular soup. He then predicted that only the potent levorphanol opiate
would bind to the receptor, because it alone
had the correct
configuration, or fit, to do so. The other one, the
dextrophan opiate, had the wrong shape to fit the receptor, similar
to the way that a right hand has the wrong shape to fit into a
left-handed glove. Goldstein’s prediction that test tubes incubated With
radioactive levorphanol would show higher numbers on the counter, reflecting a
higher degree of binding in comparison to the radioactive dextrophan, was borne
out, but the difference was so small—less than 2 percent—that no one believed
it. Nor could anyone repeat it.
Still, Goldstein was on to something, and Sol and I intended to make full use of it. What I didn’t know was that Sol had
also recognized the possibility of scoring a
coup, slipping in front of Avram and waltzing
away with the prize.
With the benefit
of hindsight, I can see how willingly I embraced this macho ethos—the intense
rivalry, the competition for credit, and the overriding drive to make the big
score, regardless of who got burned in the process. With the lack of any female
role models, I thought that to accomplish great breakthroughs in science, you had to be tough and aggressive. Most of the women I saw were stuck on the lower rungs of
the hierarchy, rarely rising above
their assigned
stations,
always stepping in to do the menial labor and then becoming invisible when it
came time to hand out the credit.
This wasn’t
going to be the case for me, I vowed. The raw ambition that permeated the
atmosphere in both Sol’s and Pedro’s labs was having an effect on me. I was beginning
to dream of what it would be like to command the money
and resources to run my own lab. From what I had observed, the only way to
accomplish this was to make a really great discovery, and it had occurred to
me, although fleetingly at this point, that the opiate receptor could be my
ride to the top.
Every morning I
made my concoction, the soup du jour consisting of either homogenized rat brain
or minced guinea pig intestine, with the addition of the new, hotter radioactive morphine. In order to make my soup,
however, I had to overcome one obstacle, and that was my lingering
squeamishness about killing a rat in order to obtain the fresh brains I needed.
I hadn’t yet killed an animal, having
avoided the issue ever since Miss Oppenheimer had let me slip by back at Bryn
Mawr. But now I was going to have to do the deed. And it did not come naturally.
I knew I had to
desensitize myself if I was to succeed, and so I began the gradual process of
rewiring my nervous system a good week in advance of my first day on the
opiate-receptor project. Each day I forced myself to stand a little closer to
the door of the room where they did the killing. After a few days, I was able
to stand in the doorway and watch as the animals were decapitated, a procedure
done with a slick little guillotine, allowing the brain to be quickly scooped
out and immersed in a cold liquid buffer that kept the neurons alive and
nourished while freezing the internal chemistry. Soon, I was able to stand
right next to the bench and watch. Then I killed one myself. My hands trembled
and my heart pounded, but I forced
myself to do it. It was so traumatic, I had to sit down after that first time
to regain my composure.
Eventually, the
ordeal became easier, but never did it become something I could do with a total
lack of feeling, coldly or cruelly. There was always a ritual to it, an awareness that this was a
sacrifice of life for life. Taking the lives of these animals so that research could be done for potential cures
to save human lives seemed like a fair trade-off, especially if done with
respect and without inflicting suffering.
Some will argue
that human life is no more valuable than animal life, and while I can well understand that
viewpoint, when it came down to it. I made the choice I believed was the right one. These white rats had been bred for research,
and scientists use them in ways I consider appropriate. In my career,
I have never seen animals
mistreated or killed in ways that promoted suffering. And if that has gone on
in the past, as animal-rights activists claim, it can no longer be the case. Today
there are strict regulations protecting animals that are used for
experimentation, and researchers must apply to committees for approval of their
testing methods.
But back to my
experiment. After a period of incubating the animal organs with the hot morphine,
I dumped my soup into the Triple M rapid filtration machine that Pedro had
loaned me, and I rinsed away the unbound material, leaving the bound ligand to
be dried right on the receptor. But how to tell if the receptor was really the
opiate receptor and not something else the ligand had bound to? Taking
Goldstein’s lead, I introduced the stereoisomer opiate dextrophan into my soup,
along with the radioactive morphine. In another test tube, I placed the
levorphanol. Since the dextrophan was an incorrect fit, I knew it wouldn’t compete with the morphine at
the receptor site, so I could expect to see relatively high counts showing that
the hot morphine had bound. The levorphanol would compete, bumping the hot
morphine right off the receptor, and thus reduce my counts. I figured the difference between the
two counts, a high one for the
dextrophan mixture and a low one for the levorphanol mixture, would give a
measure of the opiate receptor.
When developing a new technique
such as we were doing,
the rule of thumb
is to first try the least complex combination of conditions and ingredients,
and hope they work. If they don’t, and you’re faced with a busted experiment,
you can go back and try to tell which
one of the variable conditions—time, temperature, concentrations, number of
washings, and so forth—caused it to go wrong. Every experiment is like a long
chain, one that is only as strong as its weakest link. If this experiment was
to work, I knew that I had to find that weak link, and to do it I’d need to be
relentless, keeping a serious focus on mixing the ingredients of each day’s cocktail, as well as attending to the other variables.
The doors
of my world slammed shut as I put all my energy
into the pursuit of the opiate receptor. Each day
I altered the recipe, hoping to create the perfect bathing solution for my
morphine to show a specific binding to the opiate receptor. I’d usually
work long hours, transferring the contents of the last test tube around
7 or 8 P.M. Then I’d have to
put them all in the counter, a device that kept track of the radioactivity in
each test tube, somewhat like a Geiger counter. The counter sounded just like a
casino slot machine as it ticked off the radioactivity in numbers that were
then printed out on paper.
I loved the counting
room—a feeling not shared by many of my fellow
students.
It was a place where the truth couldn’t be fudged: Either you were successful
or you weren’t, because in the counting room there was no middle ground. Within
its four walls, it wasn’t unusual to hear wailing, groaning, or the occasional
joyful whoop.
I remember
how I’d place my samples
into the counter
every night, and, like
a mother hen, I’d hover over it, listening, waiting for the initial clicking
sounds, and saying a little prayer for the successful outcome of the
experiment. Then I’d go home, hoping that when I returned the next morning,
there’d be something, some numerical results that would have made our work
worthwhile.
I was also in
love with the raw data, which issued from the machine on a narrow slip of paper
like that of an adding machine. In the morning, I would gingerly gather the
data on these slips of paper in order to enter it in my lab notebook. It was
almost like a formal ceremony to me, and it heightened my desire to get there in the morning to learn the
results from the night before.
My devotion
to the data was part of the romance. After the gathering comes the crunching, scanning the data for the particular
pattern we hoped would be there. Then
I would do the massaging, or organizing the data, to bring the pattern into
sharper focus. I loved it all.
Regrettably, my
opiate data provided nothing to massage or crunch. Day in and day out, there
was only hazy noise, nothing but nonsense. I couldn’t even repeat Goldstein’s
weak signal. Weeks went by, and there still wasn’t any good news for me to
plunk down on Sol’s desk. I began to have pangs of despair. My work was my
child, a child conceived by my imagination, but now I feared it would be
aborted. There were some mornings when I had the urge to cry as I filled my
notebook with senseless numbers, and often I had to fight the temptation to throw the notebook into the
trash bin.
I was paying my dues, as they say, learning that to get an experiment right was often a case of figuring out exactly what was going
wrong. Every day I’d make the
forty-five-minute drive to the lab from the army base where we lived at
Edgewood and go over my work again
and again, looking
for where I might
have made a mistake, or what I could do to make the numbers mean something. But
despite my exhaustive attempts to manipulate the conditions and materials, I
kept coming up with gibberish.
My intuition
told me that the opiate receptor was there. When I got deep into the
literature. I noted that several opiate “experts” claimed they couldn’t find
it, so in their minds it couldn’t
exist. They were ignoring that chemists had been developing new synthetic opiates
for years, all based on theories and hypotheses
about
an opiate receptor. Even at this early stage of my career, I employed one of
the main manifestos of my mentor and refused to believe the experts. I’d
adopted Question Authority as my motto, and I knew I had to live by it,
especially now when the “experts” seemed to be winning.
Failure again, and again no hint
of a signal. Certainly, Sol had
been right about needing a
hotter trace, but evidently this hadn’t been enough. There was still another link in the chain that had
to be strengthened before I would see a clear
enough signal on the counter. I went back to my soup and continued to fiddle endlessly with the other variables in the hope that something
would work.
Two things kept
me going during this time. One was my fascination with the romance of opium and the pivotal
part it had played in the Romantic
movement of the nineteenth century. I was fascinated by the possibility of understanding the
workings of a drug that had inspired a whole generation of artists and
literati, thus sparking a revolution in thought and sentiment that swept
through Europe at the time. The idea that there was a mechanism in the human
brain that allowed all this to happen,
and that I might discover it, was absolutely thrilling to me.
When
I wasn’t in the lab, I spent hours researching everything there was to read on the
subject, delving deep into the stacks and poring over articles
that went back to the turn of the century, when heroin, the first synthetic
version of opium, began its infamous
public career. Touted as a nonaddictive cough medicine by the Bayer Company (of later aspirin
fame), it was eventually discovered to be addictive and was later criminalized.
Another reason I
persevered was purely scientific. In the medical literature I’d found a review
that mentioned the recent work of a Dr. Hans Kosterlitz, a German
pharmacologist who’d fled to the British Isles from Hitler’s Germany and was
doing research at the University of Aberdeen in Scotland. He’d proven that he’d
been able to manipulate a guinea pig’s ileum by using opiates such as codeine,
morphine, heroin, and Demerol to induce constipation in vitro. He’d also emphasized that these same opiates
were involved in human analgesia, or pain relief. How could this be, I
wondered, unless there were identical opiate receptors in the human brain and
the guinea pig gut?
I knew there was
an opiate receptor, and if I was failing to find it, it could only mean that I
was doing the experiment wrong. I continued the painstaking job of altering
variables, trying to find a way to get a signal from the hot morphine and then
measure it against the stereoisomers. If I could do this, I believed, I could
show for certain that the opiate receptor did exist.
EUREKA!
In the midst of
this anguish, Sol sent me and another student, Anne Young, off to Nashville,
Tennessee, for an intensive tutorial funded by the American College of
Neuropsychopharmacology. Fifty outstanding American graduate students had been
selected for participation in a program that was intended to thoroughly
indoctrinate us in the reigning biomedical paradigm and give us an opportunity
to rub up against the scientific superstars of pharmacology.
On the last day
of the program, the big guns jetted in to attend an extravagant banquet held in
their honor, and then jetted out again. They were all handsome, happy,
sparkling, and male, and I was entranced. Some of them I knew by name from
conversations I’d had with Sol. Among them was Dr. Julius Axelrod, who
refrained from giving a presentation, as befitted his still-fresh Nobel
stature.
I had met Julie
earlier that year, just a few months after he’d won the Nobel Prize. We were in
Chicago to attend a festschrift that
Sol had organized in Julie’s honor. Sol introduced me at the dinner, dragging
me, thrilled and nervous, over to Julie’s table, proudly referring
to me as “my little girl.” It was a term of endearment he’d used back at the lab that I’m embarrassed to admit I didn’t
mind at all. The dinner lecture was given by Floyd Bloom,
who’d come out of
the NIH with a reputation for being a prodigy and was at the time fulfilling
that reputation at the Salk Institute. After the applause, Floyd stepped down
from the podium and headed
straight for our table, where
he chose a seat right
next to mine. The experience
of being in his presence was near-orgasmic, so powerful was his allure, and my heart pounded wildly
as I listened to the conversation, too in
awe of this bastion of scientific superstars to say a single word. After the dinner, a group of us drove with Julie to a nearby bluegrass
joint, and I thought
I’d die from excitement and joy. In an attempt to put us all at ease, Julie
joked, “What kind of a drug is bluegrass?” But I was so overwhelmed by the experience of
being in the same car with a full-blown Nobel laureate that I misunderstood and
thought he was trying to have a serious discussion about something I just
wasn’t getting.
IT’S OFTEN a good idea, when faced with a
busted experiment, to put the mind on vacation and wait for the unconscious to come up with the right answer.
I tried to do this all during the sweltering eight weeks in Nashville,
but the opiate- receptor assay was never far from my awareness. I returned to
Hopkins in late August with renewed
vigor. Having had the experience of being in the company
of
world-class scientists at the seminar, I wanted more than ever to be part of the
group, which required making a fabulous discovery. But first I had to figure
out how to get my experiment to work.
I was beginning
to get the idea that the hot morphine wasn’t a good choice of trace. This
insight came to me while in Nashville, when I had come across a rather complex article authored by a
British scientist named W.D.M. Paton. He presented his notion of how two nearly
identical drugs could bind to the same receptor. One, the agonist, could
enter the receptor
and create changes
in the cell, while the other,
the antagonist, could block the
receptor by occupying it, which would have no observable effect on cell
activity. Paton called this the Ping-Pong Theory, according to which the magnitude of drug action
is proportional to how many times the drug hits, or “pings,” the receptor,
which in turn affects how long the drug remains on the receptor. Since the
antagonist doesn’t ping over and over again, it can stay longer on the
receptor, and thus block the
agonist’s access.
If Paton was
right, I needed a radioactive antagonist as a trace. Only a hot antagonist
would remain on the receptor long enough for rapid filtration to separate bound
and free drugs from one another. By the time I returned home from Nashville,
I’d convinced myself that the hot antagonist was the missing piece separating
me from my much-coveted Eureka!
It was in the
midst of this latest insight that Sol called me into his office and told me he was going to shut down the opiate-receptor assay. I was crushed.
There
were too many other things to do, he told me, to waste precious money, time,
and resources on what was looking more and more like a dead end. In addition,
Sol explained, he was responsible for seeing that I got my Ph.D., and no one
was going to give me an advanced degree for a busted experiment. In most cases,
he assured me, the Ph.D. was awarded for dull and insignificant projects that
had been wrung dry by endless
explorations of the variables.
“But Sol,” I
pleaded, “you’ve got to let me continue. I know I’m close! All we need is a new
hot trace!”
But my words fell on deaf ears. His only response was a disapproving grimace that
spoke volumes. I headed for the office door, knowing that my days of looking
for the opiate receptor were numbered, and if I was going to try anything new,
I’d better get started right away. But I stopped as he issued his parting shot:
“No! You can’t spend any more money on wild-goose chases for new hot traces!” I
looked away, bit my lip, and made my exit.
That afternoon, I brooded through
the weekly lab meeting, making my
unhappiness
obvious to everyone in the room. But Sol was unflinching. From his perspective,
a huge amount of time and resources had already gone down the drain, and what originally was intended as
a quick raid to steal the prize from Goldstein was turning into a major
campaign with no end in sight. He no doubt felt
he’d been excessively generous: He’d given me a wide berth and plenty of
resources to find the opiate receptor, and I hadn’t done it. Sol knew it had
been a long shot from the start, and now he’d decided it was time to stop
trying. He was washing his hands of it.
The next day. I begged him one more time to let me give it another chance, but he was adamant and refused to
listen to any of my ideas. The opiate project
was over, he told me in no uncertain terms, and now I was expected to
gracefully dive back into the original choline project.
But that was not my plan.
Naloxone, I had
figured out, would be the best choice of antagonist to use. I knew that if a
heroin addict was injected with a few milligrams of this potent drug, it would
totally reverse the effects of overdosing, even in the case of a coma. It was assumed
that this was due to the ability
of the naloxone to bump the heroin from its receptor,
displacing it and then occupying the receptor site itself—in other words,
acting as an antagonist. Naloxone had the right chemical configuration to bind
to the opiate receptor, but because it was an antagonist, it could not trigger
any activity in the cell, could not create the euphoria or analgesia that the opiates did.
Secretly, I
decided to get some naloxone and repeat the experiment with it when no one was
around. The only glitch in my plan was I didn’t know how to get my hands on some hot naloxone.
Then I remembered that Agu had some cold, or nonradioactivated, naloxone
at his lab in Edgewood, which he’d been using to reverse analgesia in his test
monkeys. All I needed to do was to borrow some and send it to a lab in Boston
where it would be labeled with a radioactive isotope. It would take a few
weeks, and I’d have to hold my breath, hoping that no one in Boston would call Sol to confirm the order. But I
decided it was worth the gamble. When the bill arrived from Boston, the jig
would be up, and by then I’d be either a heroine or a donkey. But I didn’t let
myself think about the latter possibility.
I sent off the
naloxone. Several weeks went by, and then one day in October, a call came that a
package had arrived and was waiting for me in Radiation Control. I quickly
retrieved it and stealthily put the hot naloxone through what I hoped was an
adequate purification process. This done, I returned to Sol’s lab and stashed the paperwork inside my
workbench.
I decided to do
the actual binding experiment that same Friday afternoon after everyone had left early for the regular TGIF pub party
or had gone home to get
an early start on the
weekend. It wasn’t unusual for me to work long hours into the night, so no one would be surprised if I waved them all good night and kept on working in the lab. But around
four o’clock, I got a phone call from Agu with the news that the babysitter had
gotten sick and couldn’t pick up five-year-old Evan from preschool. My heart
raced as I tried to think of what to do.
An hour later, I was flying down the freeway toward the day-care
center where Evan was waiting. Instead
of taking him home, I had decided
to bring Evan back to the lab
with me. It was risky, because there were strict rules regarding children being
present, especially around radioactivity, but I needed at least one more hour
to get everything set up. The actual data wouldn’t be in until Monday, but I
had to be there to transfer the brain membrane filters and put the test tubes in the counter. Somehow, I
sneaked him past the guards, and we were suddenly safe and alone inside the
lab.
“Mommy, what’s that?” Evan asked, pointing
to the Triple M.
“That’s a big suitcase,” I told him, because in fact this magical device did
look like one of those oversized metallic
suitcases. “Now, don’t touch anything,” I added in a hushed tone. I
realized that I’d have to give him something to do to keep him busy while I did the transfers. I looked around the lab quickly and seized on the thirty-six empty,
brand-new vials in which I would have to transfer the brain membrane filters.
“Honey, how
about helping Mommy take the caps off these?” Evan lit up. I lifted him onto
one of the stools and spread out the small plastic vials on the large, pristine
workbench. He became totally involved, and with one eve on Evan and the other
on my membrane filters. I completed the task.
When the last of
the thirty-six test tubes was on the counter, I turned the machine on. I had
included three variables, one for each group of twelve test tubes. In the first group of tubes was
pure radioactive naloxone; in the second, levorphanol in combination with the hot naloxone; and in the third, dextrophan in combination with the hot naloxone. Normally, I would have waited
around and stood by the counter,
getting quick counts of the numbers as they ticked out,
a rough but gratifying peek at the results within a half hour. But with Evan in
the lab, I couldn’t do this. And anyway,
I told myself, if the results weren’t
any good, I didn’t want to ruin my weekend. I set the counter to run
through the weekend, gathered Evan up, and left the lab.
I arrived
extra early on Monday morning and went straight to the counting
room. I hastily ripped
the ticker tape containing the numbers from the counter and returned to my bench. Opening
my notebook, I turned to the protocol page and
proceeded to slowly copy down the numbers, one by one. My hope was that the tubes
containing levorphanol plus hot naloxone
would have a low count, since the very potent opiate
levorphanol should block the naloxone from binding to the opiate receptor. Low numbers would indicate that a receptor
binding race
—not
unlike sperm competing for entrance
to the ovum—had taken
place, and the naloxone had
lost. Conversely, I hoped that the test tubes containing dextrophan, the
inactive opiate, would have high counts, since the dextrophan was unable to bind to
the opiate receptor, and gave the naloxone no competition. Of course, the tubes
containing hot naloxone alone, with no competition from either isomer, should
have the highest counts of all.
I had arranged
the test tubes in a staggered order: lev, dex, nal only, lev, dex, nal only, etc. The
careful protocol was the key that kept it straight. Playing a game with
myself, I kept the left side of my notebook page covered—the side where I’d written the contents of each test tube—as I meticulously copied a
single number onto each corresponding line. Low, High, High, Low, High, High. I could feel the growing excitement
buzzing in my stomach as the first six numbers
matched up to what I’d predicted.
I forced myself
to keep my eyes from running down the counter tape and seeing the remaining numbers, continuing my careful recording. Low, High, High, Low,
High, High. My heart was really pounding now. I copied the last numbers and rearranged the data into three columns.
The results were staggeringly clean, and right on target.
I had gone from no signal at all to a
signal so loud it practically shrieked in my face, and all because of a single
variable, the hot naloxone instead of morphine! This was the killer experiment
of my dreams, and I’d done it. I’d found the opiate receptor.
Anne Young was
working at the bench next to mine when I entered the final numbers into my notebook.
When I finished, I closed the book and turned to her.
“Anne,” I said,
my voice cracking from a dry throat. “I think we should go to a bar and have a
drink.”
Anne was always
ready to have a good time, but now she glanced up from her work with an expression of concern. “Why?
Are your results
so bad that you need to get
drunk?” she asked.
“No,” I said, my
voice getting louder. “No, its just the opposite!” I was shouting. “They’re
that good! Let’s go get some champagne and celebrate!”
The date was October 25, 1972.
THE NEXT morning, Sol returned from a
conference. He was usually a little cranky on his first day back from a trip,
so I wasn’t surprised to be greeted with a scowl when I burst into his office.
“Sol, you’re not
going to believe it!” I exclaimed, laying my open notebook down on his desk. “It worked!
It worked! We’ve found the opiate receptor!”
Intent and
silent, he studied the numbers I had written in the notebook, lingering over them for a full minute while I stood barely breathing
at his side.
“Fuck,” he said
in a low voice, continuing to look at the numbers. I began to feel apprehensive.
Was he getting mad because I’d gone ahead and done the experiment against
orders?
“Fuck, fuck,
fuck!” he began to sputter, and then looked up at me, his face lighting up in a
wild grin. He jumped up from his chair and began to pace excitedly around the
office.
“The ball is in
your court,” he turned and announced to me suddenly. “You can have whatever you need. You can have
Adele as your technician. Get her to repeat the experiment, and if it works,
you’ve got her for good!”
I was relieved
and thrilled. A second wave of pleasure—almost as intense as the one I’d felt
the day before, when I saw the data for the first time—washed over me. I had
made Sol happy! And now, as a reward, he was doing the unthinkable, plucking me
out of my lowly status as a graduate student and thrusting me into a league
light-years beyond, for only important senior scientists are privileged to have their own technicians to perform experiments.
Despite my
excitement, however, I couldn’t help but notice a strange glint in Sol’s eye, one I’d never seen before. He seemed ecstatic
yet oddly preoccupied, as if some grand plan were
unfolding in the inner workings of his brilliant mind. What I didn’t realize
was that, in the world of big-league science, Sol had just seen how he could win
the game. And, very soon, I would be the one he’d send out on the playing field, to score the points and claim the
victory for my team, an ascending star at the very center of the action.

PEPTIDE GENERATION: A CONTINUED LECTURE
I LOOK UP from my lectern out into the
darkened auditorium, where my audience, barely visible,
awaits my further words. A quick
glance assures me they are still
with me, and I click confidently to the next slide. As carried away as
I get telling the personal
side of my story, I remind myself
I’m here to focus
on the science, to explain the molecules of emotion and give my listeners some
context for appreciating why the discoveries my colleagues and I have made
may have profound implications for their lives. One of my favorite slides comes
up: three rats, rolled over on their backs, limbs floppy, eyes closed, obviously
in a deep swoon. “These, ladies and gentlemen, are rats in bliss,” I
usually say, and then pause for the laughter. “You can tell by their body
language that they are totally satisfied and don’t have a care in the world—the
result of injecting our furry friends with a substance
called endorphin, the body’s own natural
morphine … which your bodies make, too.”
FINDING THE KEY
A shocking but
exciting fact revealed by the opiate-receptor findings was that it didn’t matter if you were a lab rat, a First Lady, or a dope addict—everyone
had the exact same mechanism in the brain for creating bliss and expanded consciousness.
The discovery of
the opiate receptor touched off a mad scramble among scientific researchers to
find the natural substance in the body that used the receptor—the key that
would fit the lock. We knew that the brain receptor didn’t exist to serve as a
binding mechanism for external plant extracts, such as morphine and opium. No, the only reason that made any sense for
an opiate receptor to be in the brain in the first place was if the body itself
produced some kind of substance, an organic chemical that fit the tiny keyhole
itself—a natural opiate.
Less than three
years after the discovery of the opiate receptor, the natural opiate was indeed found. A Scottish
research team at the University of Aberdeen
directed
by John Hughes and Hans Kosterlitz (the same man whose work on the action of opiates in guinea pigs had confirmed
my own hunch about the existence of the opiate receptor)
demonstrated that a substance they’d isolated
from pig brains was the brain’s own morphine, an endogenous ligand that
fit the opiate receptor and created the same effects that exogenous opiates
such as morphine did. They called this substance enkephalin (Greek for “from
the head”). Later, in a much-contested bout of one-upmanship, American researchers had named their version of the substance
“endorphin,” meaning endogenous morphine. (Scientists would rather use each other’s
toothbrushes than each other’s
terminology.) The American
version is the name that has stuck.
BASIC BUILDING BLOCKS
Let’s take a
closer look at what a peptide is and how chemists came to work with them.
Peptides are tiny pieces of protein, and proteins—from proteios, meaning primary—have long been recognized as the first
materials of life. While it took over
a century for chemists to be able to determine the chemical structure of a protein and write a formula that clearly
described its elemental content and organization, we now know, as I covered
earlier in my lecture, that a peptide consists of a string of amino acids, each
joined together like beads in a necklace. The bond that holds the amino acids
together is made up of carbon and nitrogen, and is extremely tough, able to be severed
only after hours,
or in some cases days, of
boiling in strong acid. When there are approximately 100 amino acids in the
chain, the peptide is considered to be a polypeptide;
after 200 amino acids, its called a protein.
In order to
identify a new peptide, a chemist must first extract the substance and then isolate it from all other
biochemical impurities. Then the challenge is to characterize it, a process
that involves naming
each of the amino acids that
makes it up—there are twenty known major amino acids—and writing these names in the precise sequence of their
arrangement. The result is the chemical structure of the peptide.
Now, some of you
may be starting to doze, but you need to know the alphabet before you can learn
to read. Amino acids are the letters. Peptides, including polypeptides and
proteins, are the words made from these letters. And they all come together
to make up a language
that composes and directs every cell,
organ, and system in your body.
Amino acids were the first substances
extracted from living things to have
their
structures written by organic chemists—a process that began in 1806. The
isolation and identification of the body’s twenty amino acids was the result of
a series of discoveries that took place between then and 1936, starting with L-
asparagine, which was first isolated after the evaporation of a water extract
of asparagus shoots. (You may have noticed a strong smell in your urine a few
hours after you eat a large portion of asparagus—that’s asparagine!) Threonine, the most recently discovered amino acid,
and one that would be crucial to work I myself would be doing in the future,
was isolated from a human blood clot, a substance that contains the protein fibrin,
which must be boiled in acid for days
to break its chemical bonds. In order of their discovery, from the first to the
last, the twenty common amino acids are L-asparagin, cystine, L-leucine, glycine, DL-tyrosine, L-aspartic acid,
DL-alanine, L-valine, L-serine, L-glutamic acid, Lphenylalanine, L-arginine,
L-lysine, L-histidine, L-proline, L-tryptophan. L- hydroxyproline,
L-isoleucine, methionine, and threonine.
It took over a
century of work to discover the chemical structures of each of these amino acids,
with chemists performing extraction after extraction of mysterious organic
sources of protein such as silk, pancreas glands, wheat gluten, or casein from
milk, until all they were left with was white crystals, indicating that what
they had was the pure stuff.
NAMING THE BABY
But I want to return to our discussion of the substances the amino acids add
up to—the peptides. In order to determine the chemical structure of any substance, peptide
or otherwise, to write its name in terms of the atoms that
make it up, the substance must first be purified out of the organic source that
contains it, be it pig brains, guinea pig ileum, or the human brain. Once a
sample has been extracted and purified of everything but the molecule in
question, there are techniques to figure out how many atoms of hydrogen, of
carbon, of this or that, it contains.
Finally, there are physical methods
to determine how these
atoms are arranged in space, eventually yielding the formula for the complete
structure of the peptide, that is, its chemical name.
However, it took
decades of ingenious chemical discovery before these methods were developed.
Learning how to break the peptides apart, amino acid by amino acid, then atom by atom, was an immensely complicated endeavor.
Thus, for many substances, their biologically active components were identified
and
measured years before their actual chemical structure could be written, because
the biological explorations were based on a body of knowledge that considerably
predated the more sophisticated kind of analysis involved in peptide chemistry.
And indeed those
early biological explorations, which took place when peptides were still an obscure
interest of a few far-flung scientists, looked so
crude that they seemed downright primitive. Down in the dark basements of a
dozen or so laboratories, men (alas only men) labored over huge simmering vats
from which wafted the putrid odors of many pounds of pig pituitary glands,
intestines, frog skins, sheep hypothalami, and so forth. Solvents such as acidified
acetone were added to the vile soup in the vats in order to extract, or purify,
the substance that was believed to be the source of a given biological
activity. The resulting yellow brew, isolated from its confounding sludge of
impurities, was evaporated of all solvents, until
there was nothing
left of it but a dirtv powder.
Then
the powder was carefully doled out into glass dishes, each containing a
particular animal tissue, and observed for signs of activity. Could the powder make an intestinal or uterine muscle
contract, a blood vessel relax?
Some chemists injected a solution of the powder into the whole animal,
and watched to see if its ears turned red, or its blood pressure rose, or its
sex hormones surged. If these bioassays showed clear signs of activity, then
the powder would be further processed until there remained only pure white
crystals. Again, the purified substance—which
had now been reduced to what the researchers believed
to be a single peptide
molecule—would be put through the bioassays, and if its ability to
tickle receptors on the tissue was still there, then it could be said that the peptide had been
isolated. At that point the attempt to do the chemical analysis that would enable its
structural formula to be written down could begin.
By 1975,
scientists had worked out the chemical formulas for only thirty or so peptides, including, the polypeptide insulin.
Formulas were written
as a sequence of three-letter
abbreviations, each representing a specific amino acid.
In
late December of that same year, writing in the highly prestigious science
journal Nature, the Scottish team
triumphantly published their chemical analysis of the brain’s own morphine,
which consisted of a pair of peptides, each five amino acids in length. And so
it happened that two more peptides were added to the slowly growing peptide
family. But these were very special peptides,
as I’ll be explaining shortly.
Enkephalin’s
chemical structure was summed up by the following formula: Tyr-Gly-Gly-Phe-Met and Tyr-Glv-Gly-Phe-Leu. With this brief
shorthand, a
peptide
chemist had all the information needed to whip up a batch of enkephalin from
amino acid starting materials in just a few days.
A PEPTIDE HISTORY
Every peptide
has its story, and as far as we know today, there are eighty- eight stories in
the naked city called the body. I say “as far as we know today” because we
still can’t say that all the peptides have been discovered and their stories
told. Research brings new peptides to light every year. There will probably be over three hundred by the
time we are finished finding them.
The first peptide
was discovered in the gut around the turn of the century and was classified a
hormone when it was shown to act on a dog’s small intestine to stimulate the
secretion of pancreatic juices. This astounded physiologists who up until that
time had assumed that all physiological functions were controlled by electrical
impulses from the nerves. They named
the substance secretin, but
it took another sixty years to isolate it in its pure form and to determine its chemical structure. Another gastrointestinal hormone called gastrin,
which turned out to be a small piece of a longer peptide called
cholecystokinin (CCK), was discovered a
few years later and found to carry messages from the pancreas to the gall
bladder.
Another peptide,
cryptically named “Substance P,” was partially
isolated from horse brain and intestines in 1931 by Ulf von Euler. He
won a Nobel Prize for his feat, even though Substance P remained a chemically undefined “powder” for forty years, until
Susan Leeman determined its eleven-amino-acid structure in 1971. Susan Leeman,
at this writing, has yet to win a Nobel Prize; in fact, she was denied tenure
at Harvard, where, after she defined Substance P’s structure, she discovered
that the peptide’s activities went beyond those we knew about—lowering blood
pressure and contracting smooth muscle—to the transmission of pain through
certain nerve fibers.
The first
peptide ever to be replicated outside the body was oxytocin. This is the
substance that is released from the pituitary gland during childbirth to bind
with receptors in the uterus, where it causes the uterine contractions that
will eventually do the work of expelling the baby. As early as 1902, people
knew there was something in crude
extracts of farm animal pituitary glands that could be used by obstetricians to
aid women who’d been in labor a long time.
Contemporary pharmacologists, neurobiologists, and physiologists like Sue
Carter
Insel, and Jaak Panksepp have shown that oxytocin not only contracts the uterus
in labor, but also produces the uterine contractions of sexual orgasm in
females. In the brain, it acts to produce maternal behavior, stops infanticide,
and seems to help some male rodents find long-term, monogamous relationships.
This
unifying function of peptides coordinating physiology behavior, and emotion toward what seems to be a
coherent, meaningful end, is very characteristic in humans and animals, and is
something we will explore in more detail later.
It took many
months to make a synthetic form of oxytocin, but the feat was finally accomplished in 1953 by Victor du Vigneaud in his New York
laboratory. As befitting the difficulty of his accomplishment, the extremely
dedicated du Vigneaud spent his nights on a cot in his office instead
of leaving his experiments and
returning to his family on Long island. He wanted to be available around the
clock to add key ingredients with perfect timing to his difficult synthesis. For his trouble,
he received the Nobel Prize the following year. Although he produced only
a tiny amount of synthetic oxytocin for all his labors, it exhibited the
chemical traits and biological activity that proved to the world that he had
indeed replicated the simple nine-amino-acid-long peptide that was the active
ingredient in the pituitary gland. Today, a synthetic analog known as Pitocin
is used routinely to induce and speed up labor when the doctor has decided it’s
time for the baby to be born, even if the mother’s body and the fetus don’t agree.
Oxytocin is the
darling of the peptide revolution. Its importance in peptide history cannot be
overstated, because once it was demonstrated with oxytocin synthesis that
chemists could make something identical to what the body could make, they also
realized they could attempt to improve on nature. Now scientists began to make
a series of analogs, or substances
with almost the same structure by
substituting this amino acid or that amino acid for the amino acids in the
authentic sequence, and testing these various analogs for their activity. The
resulting therapeutic analogs, or drugs, could be made more potent, longer- lasting,
and more resistant to decay than the body’s
own self-healing substances.
A few years
after du Vigneaud’s nightly vigil in the laboratory, Bruce Merrifield of
Rockefeller University speeded up the process of synthetic peptide production by inventing solid-phase peptide synthesis. This was accomplished by attaching one end of a
growing peptide to a tiny plastic bead and gradually adding the amino acids one
by one, in a cleverly controlled cycle of chemical reactions. Now
easy-to-harvest peptides in large yields could be produced routinely—a feat
that literally made possible the
peptide revolution that is
exploding
around us today. Merrifield’s methodology won him the Nobel Prize in chemistry in 1984.
Today,
Merrifield’s solid-phase column is operated with computer technology and is
commercially available. Any given peptide sequence can be programmed in, the peptide reproduced in a series
of automatic steps
during the night,
and then purified out the next morning. Thanks to Dr. Merrifield, modern chemists
can now spend their nights at home and sleep with their spouses.
And yet,
remarkable as Dr. Merrifield’s accomplishment is, our bodies are capable of
making more peptides, perfectly produced in a purified state, in one night while
we sleep than all the peptide chemists
who have ever lived have made in all their high-tech
laboratories since 1953, when synthetic peptide production began. How does the
body do it? Amino acids are strung together to make peptides or proteins in
minuscule factory sites called ribosomes, which are found in every cell. A
double helical strand of DNA, the genetic material in the nucleus of the cell
that codes for the needed peptide or protein, unwinds and makes a complementary working copy of RNA. The RNA information, which is a copy of
the sequence coded by the DNA, floats to the ribosome. Every amino acid has a
“triplet code” of three nucleotides that causes a given amino acid to be
transferred and joined
to the peptide or protein growing
on the ribosome.
Marshall
Nirenberg of the NIH won the Nobel Prixe for cracking this triplet genetic code
in 1960. His work created the decoder key that has made today’s mapping of the
human genome possible.
THE PEPTIDE/BRAIN CONNECTION
At the time
Hughes and Kosterlitz revealed their findings about the existence of the enkephalins in the brain, the field
of peptide chemistry had synchronously matured to a stage where a modest number
of scientists had set themselves the task of finding the peptides responsible for a wide range of bodily activities.
Some
were looking for the peptide factors that regulated digestion and assimilation
in the gut, or the factors responsible for raising and lowering blood pressure
in the body’s circulatory system. Others were trying to identify the peptide
components produced by the almond-sized master gland, the pituitary, found at
the base of the brain below the hypothalamus. The Italian pharmacologist
Vittorio Ersparmer and his fellow researchers had found and
completely
purified over thirty peptides in a Macbethian witches’ brew extracted from the
skin of frogs. All of these chemists were working heroically, if myopically, to
purify and then reproduce their own chosen peptides, each of which was believed to issue from one
particular source and to govern one particular activity of an organism, be it
human, animal, or microbe.
The science was
young enough at the time that each discovery was greeted with excitement. But none had the impact
of the Hughes-Kosterlitz findings.
And it wasn’t simply the discovery of an endogenous substance to fit the body’s
opiate receptor that set the scientific world afire. No—it was the finding that
this substance was a peptide, one that was not only produced in the brain but
had a receptor for its functioning that was also located in the brain, that
caused all the excitement. In other words, what seemed to be local pain-relief
effects occurring in places
throughout the body were actually
mediated in the brain. This opened
up the possibility that other peptides with seemingly local sources—and effects
—might
also be produced in the brain and/or bind with receptors in the brain. Every peptide
that had been identified in the last century was now a candidate
for a brain-receptor search, a task accomplished first by using
the principles of the
tool we had developed at Hopkins—opiate-receptor assay
and the early forms of receptor visualization—and
later with more sophisticated methods such as
color and computerized in vitro autoradiography. Peptides could now be
investigated in relationship to how they interacted within the brain to bring
about many of the organism’s internal processes.
It was not until
much later that we realized that each and every peptide, no matter where it had
first been discovered, was actually made in many parts of the
organism—including, often, the brain. The pituitary peptides, it turned out,
were gut peptides after all. The frog skin peptides were also hypothalamic-releasing
hormones. The same peptides that bound to receptors in the kidney to change blood pressure could operate receptors in
the lung and brain. Moreover, many substances not previously identified as such
turned out to be peptides.
Hormones,
with the exception of the steroid sex hormones testosterone and estrogen, were
peptides. Insulin was a peptide. Prolactin, which signals a woman’s breasts to
secrete milk, was a peptide. The gut cell substances that guided every step of
digestion and excretion were peptides.
Although peptide
structures are deceptively simple, the responses they elicit can be maddeningly
complex. This complexity has led to their being classified under a wide variety
of categories, including hormones, neurotransmitters, neuromodulators, growth
factors, gut peptides, interleukins, cytokines,
chemokines,
and growth-inhibiting factors. I prefer a broad term coined originally by the
late Francis Schmitt of MIT—informational
substances— because it points to their common function, that of messenger
molecules distributing information throughout the organism.
Suddenly, even
before all the implications of the Hughes-Kosterlitz findings had begun to be
explored, peptides were an infinitely more interesting class of chemicals than
they had been before, and everyone wanted to know if their peptide was
brain-involved. In my own lab at the NIH, which was where I went after leaving
Sol’s lab at Hopkins, I began to look for brain receptors for known peptides
such as bombesin, vasoactive intestinal peptide (VIP), insulin, and a number of
peptide growth factors heretofore never believed to exist in the brain. During
that time, a veritable parade of these new neuropeptides
was being reported on an almost monthly schedule. Oxytocin from the pituitary,
insulin from the pancreas,
angiotensin from the kidney, bombesin from frog skins, vasoactive intestinal
peptide (VIP) from the gut, the impossibly named gonadotrophin-releasing
hormone (I’ve spared you its other three names!) from the hypothalamus—all of
these and more were found to be present in various locations in the brain and
to have receptors in the brain.
In my lab at the NIH, we made the assumption, based on advanced
methods of brain visualization we had developed, that any peptide
ever found anywhere, at any time, was potentially a
neuropeptide, with receptors in the brain. Adapting the new opiate-receptor
technology, we went looking for peptide receptors in the brain, intending to map the location of both the actual peptide
containing neurons and the location of their receptors. We were almost
never disappointed. Most candidates for the search were clearly shown to both
have receptors in the brain and also to he present themselves in the brain.
We were even more excited
—and
surprised—when we found that peptides existed in all parts of the brain, not
only in the hypothalamus, where endocrinologists had classically predicted they
would be confined. Peptides also appeared in the cortex, the part of the brain
where higher functions are controlled, and in the limbic system, or the
emotional brain.
It was this
mapping of the distribution of the neuropeptide receptors— showing us where
they were located and where they were the densest—that proved to be the real
fruit of the peptide research explosion. By understanding the distribution of these chemicals
throughout the nervous system, we got the first
clues that led us to theorize about peptides being the molecules of emotion.
But I’m getting way ahead of myself….
I need to pick
up the threads of the peptide revolution story back where my own role in that
revolution began, which was several years before the findings published by
Hughes and Kosterlitz. Within the world of the laboratory, the receptor that I
discovered in 1972 would have to wait for the discovery of its ligands—the
enkephalins—to fill it. But there was nothing passive about this waiting.
Indeed, shortly after my discovery, those of us in Sol’s lab pitted ourselves
against Kosterlitz’s lab in a frantic scramble to be the first to find the ligand.
They won—even though we played pretty dirty. And the story of that competition
is a story typical of much of modern science.
One day, after the opiate-receptor discovery, but before our first paper on the finding had been
published, Sol called me into his office.
“Marshall Nirenberg wants to hear more about the
opiate receptor,” he announced. “Can you drive
down to the NIH next week and show a few slides?”
“Marshall Nirenberg?!! The NIH?!!!” I gulped with terror.
“Don’t worry. He won’t bite you. Marshall’s actually
quite shy.” Sol laughed, then stifled a yawn and began to rearrange some papers
on his desk, obviously having already made his decision to send me and in a hurry
to get back to the bigger fish he had to fry.
“But next week?!!”
I gasped in astonishment. “I won’t be ready,”
I stammered.
“You’ll do fine,”
he reassured me, looking up one last time. “You need the practice. Anyway, you’ll be
giving a lot of talks on the opiate receptor soon, so you might as well get
used to it.”
4 BRAINS AND AMBITION
WINNING—it’s
the fuel that feeds the modern science machine. Being first with the facts is
what we all strive for, but, even more, being first to publicly announce the
results of the research in a top scientific journal—this is the big payoff. The
history of science is loaded with tales of people who performed a “killer”
experiment first, but were scooped in the eyes of their colleagues because a
competitor made it into print before them.
Boldness and
self-confidence are the winning scientist’s defining traits. The tendency to
ponder over or repeat experiments endlessly are the hallmarks of the second
stringer. When a paper is rejected, as is often the case for truly creative
ones, it helps when the author is willing to carry on a scathing, Solomonic, or self-righteous defense
by phone and fax with journal editors—while remaining polite, of course, with
just a hint of superstar arrogance.
GLORY
Less than two
months after the success of the opiate-receptor assay, Sol summoned me into his
office. Adele was repeating the experiment and getting good data daily, and I
had accumulated a lovely little pile of graphs and tables that were carefully scrutinized for
inconsistencies and thoroughly massaged for clarity. I think I expected that
this process would go on forever, and I suffered quite a jolt when Sol
announced that it was now time to write a paper and report our results—and that
it had to be done now. Immediately.
Sol didn’t know
the meaning of writer’s block, and had no patience with people who suffered from it. His strategy
was to speedily dictate a complete first draft, no matter how crude, with the
person who had done the most work present in
his office at the time. The first author, usually the one who had done the
work, would take over from there, editing the transcript, filling in the usual
huge holes, explaining the methods, checking every number and factoid in fine
detail, and finally returning the manuscript to Sol for a final read.
Now it was my
turn to be first author. The first thing Sol directed me to do was boil down our data for summary in two tables,
as required by Science, the
highly
prestigious journal he was targeting. Then he had me lay out my pages between
us on his desk. Sol studied the data intently, all the while yanking at his hair,
stroking his face, and emitting several involuntary snorts, as was his habit
during heavy concentration. Suddenly, he grabbed his handheld tape recorder,
leaned back in his chair,
and began to dictate: “An abundance of pharmacological evidence suggests the
existence of opiate receptors….”
Once the rough
first draft was set down, Sol was ready to teach me the further art of writing a scientific paper.
Basically, he explained, the report must be
simple and clearly written. Anything
overly elaborate, containing too many ideas, will
be rejected by the top publications, he warned. The ideal, he emphasized, was a
paper of such pristine simplicity and crispness that anyone— even the dullest
of technicians—could use it to repeat the work and achieve the same results.
Together, Sol
and I refined months of mind-breaking labor into just fifteen elegantly written
paragraphs. The title was simply “Opiate receptor: demonstration in nervous tissue,”
followed by our names, Pert, C. B. and
Snyder, S. H. This order was a matter of scientific-paper-writing tradition,
which Sol always followed: first the name of the person or persons who did the
bulk of the actual work,
last the name of the “senior author,”
who had raised
the money to make the work possible, with the names
of other contributors, if there were any, distributed in between.
As soon as we’d written the paper, I had so many nervous student qualms that
I recruited Pedro Cuatrecasas and the department chairman, Paul Talalay, to
scrutinize the manuscript before we submitted it. I was glad that they caught a
number of careless errors, but it seemed that no one but me was bothered by the
fact that we had failed to cite over twenty years of published data suggesting
the existence of opiate receptors. How else could my research be explained? I
risked making a brief
but heated argument
that we should
at least credit
Goldstein’s idea in the introduction, but lost on the basis that his
actual method was unrepeatable by others. Instead, we devoted a whole paragraph
of the summation to making it clear
that the results we had achieved with our new method bore no resemblance
whatsoever to Goldstein’s findings.
Now the rush was
on. In early December 1972, barely six weeks after I’d completed the first
successful experiment, we submitted our paper to Science. It was accepted immediately and scheduled for publication
the first week of March 1973.
A DAY OR so before the publication date, Sol called me into his office. This
time it wasn’t about the data.
“Look at
this. It’s totally worthless and boring!” he said, angrily pushing a three-page document
headlined with a Johns Hopkins
logo in my direction.
I gathered that
“this” was the press release prepared by the Hopkins media office to announce
the opiate-receptor finding. Though it seemed fine to me, Sol clearly found it
unacceptable. He abruptly turned to a dusty typewriter in the corner of his
office, scrolled a piece of paper into it, and with total concentration began
to pound the keys. Within a few minutes, he yanked the paper from the machine
and, with great relish, handed it to me.
“Now, this is a press release,” he announced.
“Please get it down to the media office right away.”
By the way he
glanced at his watch, I knew I had to hustle. Clutching the press release in my hand, I tore through
the hallway and flew down the stairs to the first-floor office, skipping every
other step as I went.
Sol’s press release was a surefire
bull’s-eye, and got the attention
of more than a few people. A
press conference was scheduled for the very next day, and I was about to
experience science as a media event for the first time. That night, I tried to
roll my hair in curlers and prepare for the conference, stopping every few
minutes to answer the phone and talk with a reporter from UPI or the Knight-
Ridder newspapers. The next day, I joined Sol and William “Biff” Bunney, a
research psychiatrist, along with a handful of functionaries from government
offices who were interested in showcasing the discovery as a major
step toward a solution
to the addictive drug problem.
When we arrived at the Hopkins
official press-conference room, we were greeted by dozens of reporters and
photographers, their flashes lighting up the space. I remember being nervous
and thinking the whole thing was a bit overblown, and was grateful when Sol and
the others did most of the talking. What I didn’t know then was that Dr. Bunney
was about to become the first head of the National Institute of Drug Abuse; Sol
was about to become one of the best-funded scientists in the world; the White
House was about to be acknowledged for funding what was heralded as
a giant step in the war against drugs;
and I was about to become famous
at age twenty-six.
The reporters
grumbled a bit when it turned out that we hadn’t actually found the cure for heroin
addiction, which had been their expectation. But it was a
good story anyway, and it instantly flew around the globe, alerting the world
that a tiny bit
of the human organism had been discovered, one long theorized about but never before
demonstrated. A new molecular sensor
too small to see, like tiny eyes or ears or taste buds, had been found in the brain. And what it sensed
were
the drugs of the opiate family—morphine, opium, heroin—causing the organism to be “turned on” and inducing the “high” that users of these drugs
often experienced. The hope that one day this discovery might help the
disperate heroin addict did not seem so far-fetched, after all.
The story
was widely covered
by the popular press: Newsweek, U.S. News,
the Washington Post, the New York Times—they all picked up on the
story and ran with it. When Newsday, my hometown Long Island newspaper, featured me in the story, I got clippings
in the mail for weeks from people I hadn’t seen since I was eight years old. The Baltimore Sun did an in-depth follow-up,
complete with a
large display photo of me and Sol in our lab coats. Pert and Snyder, the
dynamic scientific duo, the winning team, were appearing on front pages everywhere.
It didn’t
take me long to get the hang of being in the media spotlight, and I must admit that I quickly
came to enjoy it. But even more exciting was the
chance to explain the work
to our peers at the many scientific conference that year. Sol, who
generally disliked going to the more general open conferences because the
specialized psychiatric and pharmacological meetings he routinely attended were
more important to him, sent me out to stump in his stead. Perhaps he felt uncomfortable appearing before
members of the “Opiate club,” as the researchers who had been working
in this field for years were called. They weren’t his crowd. Sol was a newcomer
to their field, and could be seen by them as
swooping down to take the prize out of the hands of the “experts.” So I did the
traveling road show,
and the more I presented, the more I felt an owner’s sense of pride in this discovery.
Everyone, I found, was very excited
about the news and wanted to hear more.
A
pivotal meeting, sponsored by the International Narcotic Research Club in
Chapel Hill, North Carolina, took place a few months
after the Science paper was published. I remember my
sheer terror when I found out I’d be presenting to Avram Goldstein from
Stanford, Hans Kosterlitz from the University of Aberdeen, Albert Herz of the Max Planck
Institute in Munich—all solid members of the Opiate Club—along with many Europeans
who had been meeting informally for years. I arrived at the podium after
laboring long hours over my talk,
loaded with forty or more hot-off-the-press slides. People whose papers I had
read and whose work had inspired me were sitting in the audience. Now I was
standing in front of them, about to reveal what they’d been searching for for
years but been unable to find. My heart was pounding, my mouth dry. I fumbled with the clicker as the lights went down, hoping that when I opened my
mouth, the words I’d rehearsed for hours would be there.
One of the slides I’d laboriously
prepared had been taken from Goldstein’s classic Principles of Drug Action, so I was surprised when he jumped up at
the end of my talk to announce that the slide—which compared the three-
dimensional chemical structure of levorphanol and dextrophan—was incorrect.
Apparently, the two images I’d copied had been accidentally reversed.
“We caught the
publisher’s mistake,” the grand old man of pharmacology intoned, “but we left
it in the second edition to trip up unsuspecting young graduate students like
yourself,” he said with a half-smile.
A resounding hiss arose from the audience
at this blatant swipe. Goldstein was obviously still smarting
over the Science paper and was getting
in his licks at the upstarts, Snyder and Pert. But I knew that I had
won over the formidable crowd when, at the close
of my talk, a number
of people in my audience bounded up onto the stage to
shake my hand and introduce themselves. It was ecstatic, this moment of instant acceptance from colleagues I admired
immensely, who were so excited about the discovery that they were even willing to overlook the fact that I was a very
green, very nervous, twenty-six-year-old female graduate student.
My euphoria was
tempered by an excruciating migraine headache that began just as the crowd started to disperse. It was brought
on, most likely,
by the sudden letdown
I experienced after weeks of
prelecture preparation. But the mood
around me was jubilant, and while I was tempted to go back to my room and lie down, I didn’t want to miss the
chance to be escorted around town by Hans
Kosterlitz, who was calling for celebratory meal. Hans, who was short and
vigorous for his seventy years, was clearly taking me under his wing. We marched around the quaint college town,
followed by a parade of a half dozen pharmaceutical company chemists, stopping
in at various drinking
establishments to toast the momentous
occasion. I could barely keep up with him, as he easily downed Scotch
after Scotch, but I did lose my headache in the exhilaration. We wound up at a
steak house where we feasted on prime rib, paid for, of course by the drug
company boys, who were drooling even more over the idea of exploiting our science than over the huge slabs
of beef on our plates.
It was in the
inebriation of the moment that Kosterlitz confided to me that his team back in
Scotland was looking for a natural substance, extracted from pig brains, that
acted just like morphine when sprinkled over a certain novel smooth muscle
preparation, which he, despite my excited cross-examination, refused to
divulge. Leaning over close to me in order to elude the drug company
boys, he
whispered,
“I’ve got a new man coming into my lab, John Hughes is his name, and he’s
bright, very bright! We’re going to find it, we’ve got a way!” he boasted
excitedly. In the next moment, thinking better of his indiscretion, he
repeatedly swore me to secrecy.
Back in Baltimore
all promises forgotten, I told Sol about the encounter with Hans. “I think he’s
onto the endogenous ligand for the opiate receptor,” I told him.
Several months
earlier, Sol and I had abandoned a perfunctory run at finding the ligand
ourselves. I had brought him some promising data that pointed to a possible
ligand, but after a careful review of my data during a long meeting in his office, Sol had
finally made up his mind.
“Drop it,” he
said. “It’s too iffy, and you’ve already got plenty to follow up on with the
opiate receptor.”
But I could tell he was now more interested, and although he didn’t say much,
I suspected he was planning
to find out more about what Kosterlitz was doing.
I continued to represent
the Hopkins team at conferences around the
world, and although I learned to
adapt the humble demeanor at the lectern expected of someone presenting a very important
finding, my budding
scientist ego thrived on the strokes it received. Later,
I realized that by having me appear so often and so quickly after the discovery, Sol was ensuring
that we were staking an effective claim to the opiate receptor,
for, as it turned out, there were other claimants. One of these was Eric Simon,
a professor and researcher at NYU Medical School, who had been searching
unsuccessfully for the opiate receptor for years. Recently, he’d been experimenting with a radioactive form of etorphine, a
highly potent morphine analog used in tranquilizer guns to stop rampaging
rhinoceri and other big game. The resulting data had shown some promise, and he
planned to present it at the huge Federation of American Societies of Experimental Biology Conference in April, the month after our
paper was to come out.
Missing no
chances, Sol had managed to get himself a slot on the agenda that followed Simon’s
presentation at the meeting. Breathlessly, he showed slide after slide that I had made for him,
each displaying data from the Science paper and from the follow-up research
that Adele and I, working furiously, had produced
in record time. Simon watched, taking notes, pleased that the symposium was going well.
From Simon’s
point of view, it was clear that he was a codiscoverer of the opiate receptor.
When Sol failed to cite him as such in the early follow-up papers, he was offended
and hurt. But Simon’s very first paper not only cited
ours,
it reported the identical assay system I had painstakingly developed, using the
hot etorphine instead of naloxone. I had shown him how to use the rapid
filtration Triple M machine when he had visited me at the Hopkins lab.
Part of the
education I received from Sol, for better or worse, was not only how to effectively beat out a competitor
but also how to let the world know that you had won the race by strategic paper
citation—and omission—a point of gamesmanship he knew so well. After all, we had
published first, and that made all the difference.
EXPLOITATION
Once the initial
hoopla died down, we entered a period of intense scientific activity. Each
night, I designed experiments for Adele to set up the following morning, all
attempting to answer the many questions that the discovery now allowed us to
ask. Exactly where in the brain were the opiate receptors located? What part of the cell did they occupy?
How simple or primitive could an
organism be and still have the opiate
receptor? Now I was a frequent and welcome guest in Sol’s office as I
regaled him with my abundant new data, and together we worked long hours to
prepare papers on the results. Later, to my disgust, I learned that a few
jealous postdocs were circulating the rumor that Sol and I were having an
affair. This was a classic slur, one I was to hear again and again in
succeeding years whenever a female colleague, particularly an attractive one,
made a significant contribution and rose in status.
What was going
on between Sol and me was a far cry from the illicit dalliances our colleagues were imagining. Behind
the closed doors of Sol’s office, I was getting trained in how to
exploit a major discovery. In the scientific world, there’s no time to stop and smell the roses
after making a big
breakthrough or developing a new technique, because someone else will come
along and pick the next bouquet. The window for doing the follow-up work closes quickly, as
peers join the race and gain ground rapidly. Sol and I were out in front, and we were planning on staying
there for a while.
While I was
working out the kinks, Sol got some of the other people in the lab to try out the new technique to see if
they could use it to look for additional neurotransmitters. Anne Young (then a
medical student, now the head of neurology
at Massachussetts General Hospital) was the first to hit paydirt. She used the rat poison strychnine, which causes convulsive muscular contractions,
as
a radioactive antagonist to find the receptor for the neurotransmitter glycine,
which causes muscular relaxation. Instant Eureka! Immediately, Sol switched all
his postdocs over to our method and directed them to use it to scan for
receptors for all the known brain chemicals. When I showed signs of getting
possessive about my hard-won methodology, Sol ordered, Adele to show everyone
the ropes—how to make the “magic membranes,” as I called them, when to mix the
test tubes vigorously, how to filter—all the little tricks of the trade Adele
and I had evolved to guarantee good
data even day.
Sol ordered a
dozen new Triple M’s and thousands of dollars’ worth of radioactive ligands.
Like manna from heaven, successful binding assays for the various
neurotransmitters began to rain down on the blessed lab in the heart of
inner-city Baltimore. While it had taken me months to work up the procedure
from scratch, positive results from new receptor assays seemed to fall from the
sky on the first or second attempt. The norepinephrine receptor! The GABA
receptor! The dopamine receptor! We found them all.
We were learning
that each receptor has its own special requirements for the conditions—the soup
do jour—in which it will reveal itself. One receptor might show binding when
its soup was loaded with sodium, while another preferred a heavy dose of
chloride. Getting it right might take the postdocs hours of fiddling, but their
job was nothing like the seemingly Sisyphean chore I had done to get it
straight the first time, when everyone around me believed it was
impossible!
One of the first
questions we tried to answer regarding the opiate receptor was why some drugs
like morphine and heroin fit the receptor and caused enormous behavioral
changes, while their antagonists, like naloxone, nearly identical in chemical structure, fit the receptor
and resulted in no change,
in effect blocking or “antagonizing” any further
activity. Moreover, if an antagonist like naloxone was put in competition with
morphine, it would move in and bump the morphine right off the opiate receptor,
which was why it was such an effective antidote for heroin overdose. But how
did this happen? A clue to this mystery came from an observation I’d made in my
original opiate-receptor assay, which was that
naloxone required sodium to perform its blocking action.
My first big
follow-up finding came as the result of a turf battle that I fought on two
fronts, playing hardball to keep the opiate receptor from slipping out of my
hands. In the paper he finally published, close on the heels of ours, Eric
Simon pointed out that etorphine, the big-game tranquilizer he used in his
experiments, was weakened when sodium was added to its soup. The only
difference between his results and ours, he reported, was that his etorphine
binding was diminished by the presence of sodium, while our naloxone’s was
boosted.
I wondered if this sodium difference could be the clue to one of the biggest
mysteries in pharmacology: What makes one drug (like etorphine) an agonist, and
another drug (like naloxone), which is almost identical except for tiny
molecular differences, an antagonist? Why does etorphine mimic morphine in all its effects from euphoria to muscle
relaxation, while naloxone blocks all the effects of these and other opiate drugs? Both
agonist and antagonist were believed to bind to the same opiate receptor, but somehow
their “intrinsic activity”—the effect they had on the cell—was different.
As soon as Sol
spurred me on with a preprint of Simon’s paper, I raced to set up an experiment to prove that sodium was
the decisive factor, the one that could be used to tell the difference between
an antagonist and an agonist—and not just between etorphine and naloxone, but
between the agonists and antagonists in a whole cornucopia of opiate analogs we had by now accumulated. As I concocted a nifty little system for
testing this “sodium shift” on all of these opiates, it was easy to stay two steps ahead
of Eric Simon.
But I was facing a new challenge from Gavril Pasternak, a
medical student who was spending some time in Sol’s lab, and who, behind my back, had been steadily
encroaching on Adele.
Sol had put
Gavril on a project that involved the purification of the opiate receptor
itself, a problem he was not able to crack with the prehistoric methods
available in those days. Hitting a dry hole, Gavril had started to explore how some of the chemicals off the shelf
affected opiate-receptor building, and so had reason to commandeer Adele when
she wasn’t busy with the experiments I had assigned her.
At first, I
tried to ignore this infringement on what I considered my territory and concentrate on validating my method
for discriminating agonists and antagonists in the test tube. My results were
good, and, once again, I was making Sol jump for joy. The applications for this
new testing system were enormous. It meant that a tiny quantity of any untested
new chemical could be screened for its ability
to be an agonist or antagonist in a day instead of the weeks or months it had taken
previously. Very quickly and very precisely, I could point to where in the spectrum between
agonist and antagonist any given opiate was to be found.
The drug
companies soon caught wind of what we were doing and were agog, since, at the time, they were looking for “mixed agonist-antagonist” drugs, that is, drugs
that acted like agonists in one test, antagonists in another. Such drugs, they
believed, would have an incredible potential as nonaddictive opiate pain-
relievers. A dream come true for a drug company! I loved seeing Sol dance with
pleasure as I handed him slides
showing the intrinsic activity and potency of
these
substances, samples of which the pharmaceutical industry had given us to test
with my new techniques.
But at the same
time, part of me was distracted, feeling I couldn’t turn my back on Gavril as
he scurried around with his test tubes doing God knows what with my opiate receptor. I knew something was up, and it made me nervous.
More
and more, Adele was doing his bidding, and when I complained, Sol shrugged and
offered no response. I tried to convince myself that it didn’t mean anything.
After all. Adele was so efficient, and the opiate-receptor assay so simple, even sharing
her with Gavril couldn’t possibly fill her days, But no, there was something
more, and my suspicion continued to grow.
It wasn’t long
before I got the news. Now it was Gavril, instead of me, locked up with Sol in
his office for hours, supposedly writing a paper on Gavril’s findings.
When they emerged,
Sol asked me to give the draft
a quick critical read, because they were expecting
to submit it to Science the next day.
A quick glance told me Gavril was claiming that EDTA, a component of his assay
solutions, acted in the same way as sodium did, and had an equal ability to
discriminate between opiate agonists and antagonists.
I took the draft
of the paper home and pored over it that night, sensing that something was wrong, but unable to put my finger on it. The next morning,
I was still racking my brain as I made the forty-five-minute drive to
Baltimore. It hit me just as I was
making my exit—EDTA had a negative charge and needed a positively charged ion
to balance the crystal. The balancing ion must have been sodium! I could hardly wait to get to the lab to check the reagent
bottle to confirm my
suspicion. I was right—the label said sodium
EDTA. Gavril had mistaken the EDTA as the agent of action when it was
really the sodium in the solution that was responsible. He had inadvertently
proved my thesis!
If I’d had less
of a competitive streak, I might have kindly offered a suggestion: “Hey, you
guys should double check this, I suspect that it’s the sodium, not the EDTA, that is responsible for discriminating the binding action
…”
But instead, with an evil glee, I grabbed Adele and got her to do a quickie
experiment, comparing the discriminating abilities of sodium chloride, sodium
EDTA, and a nonsodium EDTA. The EDTA alone did nothing, while the sodium soups
were the clear winners. I walked into Sol’s office and cockily slapped my data
down on the desk as if it were the ace of spades.
“Boy, you’d
better keep closer tabs on Gavril,” I announced. Sol looked up at me, clearly
puzzled. “You guys almost humiliated yourselves with that paper.”
After that, the opiate receptor was mine. I had won the battle, but Sol never
treated me quite the same. I had gotten
down in the dirt to scrap with the boys and had emerged victorious, as a new
strength to be reckoned with. From that moment
on, I was no longer the innocent “sweet baby girl” in my mentor’s
eyes.
THE
UNRAVELING of the many
mysteries about the opiate receptor continued to occupy our attention. Although
the dominant image of the receptor was one of a lock that opened when the right
key, or ligand, fit into it, I was beginning to understand that this metaphor
was not an accurate one. The idea of a lock and key was much too static, not nearly dynamic
enough, a description more appropriate to the
older, more mechanical Newtonian paradigm than to the facts as we
were seeing them. I was starting to realize that the receptor changes shape,
switching back and forth between any number of predominant configurations, all
the while vibrating and swaying rhythmically to some as yet unknown melodic key.
In addition
to studying the action of the receptor, my other preoccupation in the lab was gathering data to show the distribution of opiate receptors in the brain. In what
locations were they the thickest, where the sparsest? I was also curious about
how the opiate receptor had evolved over time, so I attempted to measure them
in brains of the vertebrates, starting with the gruesomely ugly hagfish, the
lowest true vertebrate, and moving painstakingly up the evolutionary chain
through snakes, birds, and rats, eventually reaching monkeys. They all had
opiate receptors, which meant that this molecule had been conserved over time,
through eons of evolution, and therefore probably
had been of great importance to the organism’s survival.
I knew the day
would come when I’d have to go looking for the opiate receptor in the human brain, but I was completely unprepared
when Sol called me into his office
one spring morning in 1973 and told me to contact the Baltimore city morgue,
pronto. He’d heard that a competitor was planning to publish data from a study
of opiate receptors in the human brain, and our latest paper, which
we had just prepared for Nature,
contained only monkey-brain data. Sol wanted me to get
some human brains, run them through my assay, and quickly assemble
some data to add to the paper before it went off to the journal.
I called the morgue every day at dawn for a week until, finally, I got word
that three still-warm human brains were ready to be picked up.
When I arrived
at the morgue, the pathology clerk sent me to a room where I saw three naked
bodies lying on three separate tables, their brains not yet having been
removed. One, I was told, was a man who had dropped dead playing tennis that
morning, and the other two were a liquor store owner and the young man who had attempted to rob him. The ensuing
crossfire had cost them both their
lives,
but provided me with the materials I needed to do Sol’s bidding. My heart was pounding
as the patheologist went to work, eventually placing a brain in
each of my three ice buckets. I thanked him coolly, as though I saw brains
being removed from naked dead men’s bodies every day.
After the
retrieval, we followed a set routine. Mike Kuhar, a former graduate student of
Sol’s and now assistant professor at Hopkins in neuroanatomy, dissected the
brains in the cold room. I watched as he scissored out chunks from each of the
major sections—frontal cortex, hypothalamus, visual cortex, cerebellum,
amygdala, etc. It was then my job to
weigh each chunk and place it in a test tube, adding enough liquid so that Adele could whip the
mixture into a frothy milkshake on the Polytron, a fantastically expensive
machine that made a deafening noise. Once liquified, the mixture was dosed with
radioactive naloxone, incubated for
an hour, and then put through a filtering process. The brain-laden filters were
then placed in the counter to determine how much radioactive naloxone actually
did bind.
I remember
sitting in the counting room late into the night, listening to the crunch and
tinkle of the machine. When I emerged, the lab was silent. Everyone had gone
home, and it was my turn to do the clean-up.
Many times in
the laboratory I’ve felt I was moving close to the mystery, but never more
powerfully than when I walked back into the cold room that night and saw the remains of
those three human brains—three-pound universes when alive, in death looking
like nothing so much as half-eaten turkey carcasses— waiting to be swept into
the garbage. The fragility of life, the ruthlessness of science, the folly and
beauty of it all moved through me, striking an emotional chord so powerful I
can still feel its vibration.
I finished the
clean-up, closed the lab for the night, and went home. The next morning I was
at my bench, entering the numbers from the counter into my notebook, when Mike
waltzed in and slapped a Baltimore Sun down
in front of me. He pointed to the
lead story, which gave the details of the previous day’s liquor store robbery
and described its owner, along with quotes from grieving relatives and a
photograph of him in happier times. It was difficult for me to do what seemed
so easy for most of my colleagues, to distance myself from the human element.
I looked at the picture
of this man and then at the numbers in my notebook, wondering how he would
react if he knew we’d made a milkshake of his brain. Considering what he’d done to the guy who had tried
to rob his store, probably not too cordially, Even so, I hoped he’d be
glad to have helped in the fight against drug addiction.
As soon as we had gathered our data, I watched as Sol called Walle Nauta
at MIT and read him our numbers. Nauta, the dean of American neuroanatomists,
was able to analyze the data and let us know after a few minutes of studying
the numbers in what part of the
brain’s anatomy we had the strongest signals.
“Walle says it’s
a limbic configuration,” Sol informed me. The opiate receptors, it turned out,
were showing up most densely in the limbic system, the part of the brain
classically known to contain the emotional circuitry.
Looking back on
that moment, I can see that this should have been the first clue in the search
that eventually led me to a theory explaining the biochemistry of emotion. But
at the time, I was so impressed by the ability of Walle Nauta to look at our
numbers and translate them into an image of the brain, that I missed the
significance of the limbic configuration altogether. To have such mastery over such complex
data—I couldn’t imagine
anything more spectacular than that. My focus was so single-pointedly fixed on
understanding the cellular and molecular level of the brain,
that I failed to be interested in the bigger
picture, the notion that the receptors might be part of a network
designed to handle something so fundamental to the organism—emotion—that it
must surely have profound implications for the functioning of that organism.
Emotions, so often dismissed by scientists as intangible, if they were ever brought
up at all, must matter somehow. But how they mattered I had not even
begun to wonder.
One thing we knew with certainly, but had not yet been able to prove, was that the opiate receptor had quite a
lot to do with the organism’s pleasure/pain continuum, which in turn,
we felt sure, was crucial
to the survival of the organism. As far back as the 1950s, behavioral psychologists had diagrammed the pathways of the nerves that
carried pain from the skin to the brain, where the information was processed at
pain centers. They discovered that by electrically stimulating these centers in
rats, behavior indicating pain would occur. They also found that other points
in the brain processed pleasure, and if the rat was wired
to self-stimulate, it would do so for hours until collapsing from exhaustion.
Now we were asking what the role of the opiate receptor was in this continuum, and our hunch was that if we followed the
receptor trail, we’d come upon a clear understanding of the network in the brain that controlled pleasure
and pain.
One morning, as
I was leaving for the lab, Agu called out to me: “Don’t forget to check the
periaqueductal gray for opiate receptors when you dissect those monkey brains
today.”
Agu had read in
a journal that Chinese scientists had followed morphine to a site of action in the brain called the periaqueductal gray. PAG, as it’s known in
the
jargon, is located around the aqueduct joining the third and fourth ventricle in the midbrain, and is a nodal point
where many nerves converge for information processing. Although it was not
classically considered part of the limbic system, it clearly had neuronal
pathways that hooked it into the limbic system. Agu had been able to confirm
the Chinese researchers’ observations in the behavioral brain-mapping
experiments he was doing in his Edgewood Arsenal lab, and we were also aware
that John Liebeskind and Huda Akil of UCLA had published data hinting that
certain types of electrical stimulation of the PAG might be causing the release
of a morphinelike factor.
Sure enough, our lab tests confirmed that the PAG was an area where
opiate receptors were highly concentrated. And Agu proved that the PAG was the
area of the brain where the perception of pain is determined—or, as we would
put it, the pain thresholds are set.
This last
experiment caught the attention of a lot of people, among them an Englishman
named John Hughes, who was laboring in the University of Aberdeen lab run by
Hans Kosterlitz, my Chapel Hill host and secret (but indiscreet) seeker of the
opiate receptor’s endogenous ligand. Hughes, a bright young man Kosterlitz had
told me, was new to Kosterlitz’s lab, and had been spending his days trying to
isolate a substance from pig brains that seemed to behave just like morphine
when applied to certain tissues. He was beginning to wonder: Could we have found it? Was this the body’s own natural
morphine?
THE RACE
The frenzy
that accompanied the search for the brain’s
own morphine was like what happens when you wave a
filet mignon in front of a pack of hungry dogs. Before the competition climaxed
in a major discovery, there was more adrenaline pumping in scientific circles than flows through the drivers at the
Indy 500. Labs on both sides of the Atlantic Ocean raced around the clock to
get to the finish line.
But the work
Hughes was doing was immensely time-consuming and labor intensive—about as far from the style
Sol had taught
me back at Hopkins as could
be. Daily, he visited a local slaughterhouse and acquired wheelbarrows full of pig brains, which he
took back to his lab. There he reduced them to proteins and salts by grinding up the
foul-smelling mess with acetone to dissolve the fat, leaving it to evaporate and then redissolving the residue in various
solvents, until, finally, he managed to extract a waxy, yellow material.
A Eureka moment came for Hughes when he was able to show that the extract acted like morphine in the
organism and was blocked by naloxone. This he did by demonstrating that a smooth muscle
called the vas deferens in mice contracted in the presence of his mystery
material, creating spasms that could be reversed by naloxone. Hughes now had
both a method for purifying the extract and an assay to demonstrate its
activity. But until he could crack the molecular sequence and write the structure,
the race was still on.
As recounted
earlier, when I returned from the Opiate Club meeting in Chapel Hill during the
summer of 1973, I had tipped Sol off about the goings-on in the Scottish lab,
and so we decided to invite Kosterlitz and Hughes to a small neuroscience
conference we were organizing for May of 1974 at an elegant mansion in Boston.
The tiny but elite conference was one in a series designed to bring leading
researchers together to discuss various subjects in a collegial fashion. Shortly after
the conference was closed, a pamphlet summarizing the proceedings would be
published in the Neuroscience Bulletin.
Though not a regular scientific
journal, the Neuroscience Bulletin was considered a legitimate enough forum to
establish a solid claim, should Hughes reveal his work and wish to have it in print. In my correspondence
with him beforehand, I assured Hughes that if he decided to tell all about the morphinelike substance
at the conference, he could do it safely without fear of being scooped,
because the pamphlet would establish his primacy in the field.
Hughes had good
reason to be hesitant. Calling his new substance enkephalin, he had been able
to identity part of the chemical structure, but hadn’t gotten far enough yet to
crack the whole formula. It could have been a disastrous move for him to present his most recent
but incomplete findings
at our meeting, considering Sol’s reputation as a shark and the fact
that Avram Goldstein, who’d been on the trail of the body’s endogenous morphine
for years, was planning to attend.
Trusting me,
Hughes decided to present his findings at the Boston meeting. In his talk, he
revealed that although he hadn’t been able to determine the complete structure
of the substance, he had done enough work to know enkephalin was definitely a
very small peptide.
The minute
he stepped down from the podium, an exodus began
from the hall, as people
scrambled for phones to call their labs and spread the news. A peptide! The
revelation that enkephalin was a peptide enabled all kinds of clever end runs to be attempted. Avram
Goldstein, for one, was eager
to find his own
source
of the mysterious ligand, and, knowing that the pituitary gland was a rich
source of many peptides, began to stock up on pituitary extract, which he acquired from commercial meat-packing
companies.
I felt terrible
as I watched all this, thinking I’d led Hughes like a lamb to the slaughter.
But at the same time, I understood that this was the way the game was played.
And why not? Why should Hughes be permitted to take his time in making a major discovery that could
potentially benefit millions? In fact, Goldstein’s approach ultimately led to
the discovery of several completely new and important forms of natural opiate
peptides.
The day after we got back to Hopkins, Sol lined us all up in battle formation for a run at the
still-to-be-cracked molecular structure of enkephalin. As I sat in a meeting
and listened to Sol map out his strategy, my inner conflict grew. I couldn’t ignore a gut feeling that
something was very wrong. Certainly I could sympathize with Sol’s desire to win
this race, but what seemed to me a clear lack
of respect for the integrity
of Hughes’s work left me sick to my stomach.
I was too upset to say
anything, and kept my feelings to myself.
Some of my
revulsion was the result of being pregnant with my second child, Vanessa. It
wasn’t morning sickness that was the problem, however, but the fact that the
hormones of pregnancy seemed to have caused me to lose my macho- competitive
tendency. What I really wanted to do was take a break from the fast lane and do
something else until the baby came. The day after our meeting, I told Sol I had decided
to pass on this one, even though
I knew that would mean giving up Adele. My Ph.D. had been
granted on the basis of the opiate-receptor work, and the next thing for me to
do was begin my postdoctoral training. One project that interested me was
working with Michael Kuhar to develop a method that would allow us to see the
actual distribution of opiate receptors in the brain. The possibility of
getting a visual image for what Walle Nauta had seen in the numbers—the exact locations of the opiate receptors in the brain—fascinated me, and Sol agreed to let
me pursue it.
But the days of
basking in the warmth of Sol’s attention were at an end. Now the hottest
project in the lab was the race to be first to find the chemical structure of
the brain’s natural opiates, and I had dropped out. Within weeks of Hughes’s
announcement at the Boston meeting, Sol and his student Gavril used peptide
procedures to extract a brain substance they called MLF, for morphinelike factor, although they
couldn’t yet write the formula, either. This work, done in Sol’s lab weeks after the Boston
meeting, now appeared
in the same Neuroscience Bulletin
where Hushes reported
his findings, making it appear
that
the
two labs had done their work simultaneously. Again, I was embarrassed for
having urged Hughes to openly announce his findings, and shocked that Sol would
go to such lengths to make it look like he was neck and neck with Hughes. But that’s as far as Sol and his
students got. All that year and into the next,
they hit MLF hard, but were unable to crack its molecular
structure.
THE HARE TURNS TORTOISE AND DROPS OUT OF THE RACE
My work seemed
much less exciting, having none of the high drama that accompanied the search
for the endogenous ligand, but I was content, in my pregnant bliss, to plod
along at my task. Straightening out the many technical glitches involved in
getting a clear radiological picture of opiate receptors in the brain was by
far the most tedious and exacting job I’ve ever done. It was a project perfectly
suited to a very pregnant woman who had all the time in the world, and plenty
of patience to spare.
Autoradiography,
as the technique was called, had been around since the 1950s, and essentially
involved injecting an animal with a radioactively labeled substance, such as
naloxone, killing the animal, and then removing a sample of the desired tissue
for study. On exposure to film, the radioactive substance would appear as a
bright spot of light in the tissue. The challenge was to figure out how to get
enough of the radioactive naloxone to stick to the receptors, and thus give a
precise image. I worked meticulously at ironing out all of the technical
niceties for five months alongside Mike Kuhar, whose knowledge of neuroanatomy
contributed immensely.
As soon as we
had the method perfected, we began constructing a map of the opiate receptors
throughout the brain. Using chunks of brain from rats that were nine, fifteen,
and twenty days old, I worked with Joe Coyle, another assistant professor in
the department (now the chairman of the Harvard psychiatry department), to slowly build
up a picture of how opiate receptors
developed in the brain. We
saw how they were concentrated in areas that were classically associated with emotion, pleasure
and pain, and sense perception. This confirmed the work I’d done earlier, locating the
receptors in the vertebrates that ranged evolutionally from hagfish to monkeys,
once again demonstrating to me that the system we were looking at was one that had been conserved for eons of
evolutionary
time, thus one that had to be very basic and fundamental to the survival of the
species.
In a classic
example of acquiring a scientific rhythm, we had developed a technique and were
exploiting it fully, building up a database without paying too much attention
to what it all might mean ultimately. I was learning that life in a lab can be a very left-brain exercise, much
of the time spent doing endless variations to try to make an experiment work,
hoping to extract a signal from an ocean of noise. And then once a signal is
heard, the rest of the time is devoted to asking all the questions the new
finding allows you to ask. This can go on for years, and often does, keeping us
scientists occupied and busy in our laboratory worlds.
VANESSA WAS born in the spring of 1975 and,
after spending a brief time at home with her to bond and establish a
breast-feeding, breast-pumping routine, I returned to Sol’s lab to finish my postdoctoral work over the summer. That June,
I accompanied Sol and Gavril to the annual Opiate Club gathering, now being
officially called the International Narcotics Research Conference (instead of Club),
which was held at Airlie House in a suburb of
Washington. I arrived for the two-day affair with the slides
I’d prepared to present opiate-receptor autoradiographv for the first
time, and with a batch
of empty Playtex
baggies that I planned to fill with breast milk for the infant I had
left at home.
The decision to
leave Vanessa with a nanny had been a difficult one. I knew the meeting would be tense, with Hughes’s
report of the molecular structure for enkephalin imminent, and a throng of
competitors poised to spring and claim primacy. I envisioned the testosterone frenzy
that would surely
be the mark of this meeting,
and I didn’t want to expose my new baby to the harshness of such
an environment. Alternately, and somewhat paradoxically, I wanted to be ready to
leap into the fray myself
and do battle with the boys. But if I wanted to present a strong front, having a
brand-new baby suckling at my breast wasn’t the way to do it. That was a
scenario I couldn’t quite imagine.
At the meeting, I watched
from the sidelines as the clash of
the titans got under way. Each of the
competing researchers presented his version of the endogenous opiate ligand,
all of them vying furiously for first place in the race. To say the boys were getting edgy as
they bore down on the finish line would
be a vast understatement.
Gavril gave his
talk first, revealing his and Sol’s findings without giving credit to the
pioneering efforts of Hughes and Kosterlitz. He was quickly upbraided by an irate Kosterlitz, who leapt to his feet, demanding an apology
and
a corrected statement of the facts. Gavril, his face turning bright red,
responded that there had been no time in his talk to mention the Scottish team, but that he had cited
them in the actual paper he had submitted for the proceedings of the meeting. I took pleasure in seeing my old
rival humiliated, so caught up was I in the drama of the competition, the lust
to win. Yet I also knew my own role in trying to steal Kosterlitz’s thunder.
The climax of
the meeting came during John Hughes’s talk, when he dramatically ripped open
the envelope of a freshly arrived telegram (these were prefax times) to
triumphantly announce the latest analysis of the amino acid content of his
enkephalin extract. But he still didn’t have the much-coveted sequence needed
to write the formula. For that we would have to wait six more months.
NEW HORIZONS
The day arrived
when, having completed my postdoctoral work, I was expected to leave Hopkins and find myself a real job. Sol, who,
unlike many lab chiefs, prided himself on finding the best possible positions
for his students, was tremendously supportive. He used his influence to get me
an offer from the National Institutes of Health, for which I was very grateful.
But because of the opiate work, I soon found
out, I was a bright star in demand. A dozen
universities offered me faculty positions. In the end, I decided to accept the
NIH offer, partly because Agu was offered a position there as well, but more
because my burning desire was to do pure research, and at NIH I wouldn’t be
required to teach classes or write grants or advise students.
It was time to
leave the nest, never an easy transition for child or parent. I felt like a bright but awkward adolescent pushed a bit prematurely from my
scientific home, but eager to embark on the adventures that lay ahead. It was a
classic mentor-disciple, father-child transition that was taking place. As the
time for my departure drew closer, there was a palpable tension between Sol and
me, one that seemed to be exacerbated in the fact that what he and I had in
common was not a genetic but a scientific bond. But there was more to the
tension than that.
When I went to
say good-bye to Sol in his office on the last day, I remember how awkward we
both were, exchanging platitudes, neither of us saying what we really felt. But
suddenly he said to me, in a
tone of real finality. “Candace, I
want you to promise you won’t work on the opiate receptor
in your new job.”
My heart sank. I was stunned. Even though I hadn’t really thought about what
I’d
be working on, this request seemed unfair, even cruel. I grunted and mumbled
incoherently, which seemed to satisfy Sol, and made a hasty exit before he
could ask me to sign on the dotted line.
Later I
wondered. Why didn’t Sol want me to work on the opiate receptor? Had I upstaged him by
my many conference appearances, making myself a star while he stayed behind in
the shadows? Suddenly, I remembered an incident that had made no sense when it
had happened a few months before. I was sitting on the centrifuge in the counting room and
talking to Sol, who had a habit of contorting his body and resting his elbow on
his knee, chin in hand, presumably so he could think better,
when there was a pause and he stared at me intently
for a full minute. As if he had just seen me in a new and puzzling
light, he said, “Have
you ever heard of The Prince by
Machiavelli?”
Now,
political science had never been my forte, but I vaguely knew that The Prince was a classic work that had
been written in the sixteenth century to instruct
princes of the time in how to use any means at their disposal to gain power and
manipulate the masses. Why Sol would be mentioning it to me then I had no idea.
“You really
should read the chapter about killing the king,” he said dryly, straightening
up. Then, looking me straight in the eye: “If one is going to kill the king, then one should
never wound him, but finish
the job and be done with it.”
I stared at him blankly, having no idea what he was talking
about. Later, when I pondered the incident, I wondered if I’d been too aggressive when I asked to be
listed as coauthor on an article summarizing our work together that was about
to appear in an upcoming issue of Scientific
American. I was left with the disturbing thought,
Was my growing ambition becoming
a threat to Sol?
5 LIFE AT THE PALACE
THE PALACE
I arrived at
Bethesda in September of 1975 to begin work as a staff fellow in the biochemistry and pharmacology section
of the biological psychiatry branch of the National Institute of Mental
Health (NIMH). This was a subsidiary of the larger National Institutes of
Health (NIH). During my stay there, from 1975 to 1987. I published over two
hundred scientific papers, and, for a while, was the most cited scientist at
the NIMH. Although much of my success can be traced to the methods and
techniques I invented, some credit must be given to my having been in the right
place at the right time. The field of receptor science was exploding in the
late seventies, a time when new neurochemicals, most of them peptides, and
their receptors were being identified practically every month.
Spread out
across hundreds of lawn-covered acres in a suburb of Washington, D.C., the
National Institutes of Health is the home base of the United States
government’s premiere biomedical research establishment, which puts our tax
dollars to work to support
research in pursuit
of answers to all the big questions of health and disease. Though
most of the NIH’s budget is deployed through universities and research
institutes scattered throughout the country, the headquarters are here, where
the laboratories and offices are housed in sixty-five all-brick buildings, and
roughly 13,000 employees are divided among eighteen subsidiary divisions, one of which is the
National Institute of Mental Health.
During
the thirteen years I spent at the NIMH as a research scientist, I referred to
the entire conglomerate as the “Palace”—partly out of affection, because it
truly was a dream kingdom come true, a veritable Versailles, opulently funded
with seemingly endless freedom to do research, partly with irony, because of
its rigid political hierarchy and the sharply cut boundaries that divided the
disciplines, carving up the turf. It seemed as if the old paradigm’s insistence on the separation of one biological system from another,
as well as mind from body,
was as solidly entrenched as the old brick buildings
in which the research on those systems took place. Science as an
interdisciplinary, interdepartmental phenomenon was an idea whose time had not
yet come to the NIH.
Even today, a casual visitor would be instantly
aware of the hierarchical
compartmentalization
of the Palace, a quality made visible by the subtle but pervasive dress
code. At the bottom of the hierarchy are the muscles,
who travel in packs,
dressed in bright
blue or orange
jumpsuits, passing through
the hallways at all times of the night and day, repairing the many vital
systems of the infrastructure. Above them are the lab coats, the technical
assistants, like Adele, who serve the mostly male postdoctoral students, who
form the next category up the ladder and are
invariably marked by their
jeans-sneakers-T-shirt uniforms.
These
last two categories are the worker bees, dominating the general populace and
forming a huge pool of willing arms and bright minds. Above them in the
hierarchy are the alphas, the permanent senior scientists and all those who are
poised to move into tenured positions. These folks all dress distinctively,
expressing their unique and privileged individualism. And, at the very top, are the brass, the reigning princes (no
princesses among them!), and the lesser barons, who administer the complex
beehive of laboratories, offices, and institutes and control the resources. All
the top brass are medical doctors, and they all wear suits and ties.
And then there
are the gypsies, whose place on the ladder is rather vague, somewhere between
worker bees and alphas. This is a group of older researchers who never made it
to alpha status but are addicted to the Palace, research junkies who roam
freely from laboratory to institute, valued for their knowledge of the system,
which, over the years, they have learned to manipulate. Some of them may have left for a while but felt
compelled to return, so attractive is the atmosphere of the Palace, offering
them a kind of energy and excitement to be found nowhere else in science.
At the NIMH,
where I worked, the brass were all psychiatrists, medical doctors whose
territory stops at the neck. The alpha scientists, who had Ph.D. degrees like myself, work for the medical doctors,
feeding them data to present at the many conferences they
attend around the globe. A wise scientist will seek out a niche protected by a
powerful M.D. and be content to stay there. No matter how smart or productive
he or she may be, the scientist with a Ph.D. has absolutely no chance of ever rising to a position of controlling
resources. M.D.’s only need apply.
This
intellectual imbalance creates a certain amount of friction between the two categories, scientist and medical
doctor. Success often depends on a certain amount of sucking-up to your
superiors, something that doesn’t come easy for a lot of brilliant scientists.
During my years there. I saw more than a few who weren’t willing to play the
game, usually because they considered their boss an imbecile who wouldn’t know an experimental breakthrough if it strolled into his
office
and burst into song. While most of the doctors high up in the Palace had a
passing familiarity with experimental science, few were experimenters, and they
often had a difficult time evaluating data, particularly when two experiments
conflicted. But they were in charge, the princes, the power-boy doctors,
and I saw more than one frustrated scientist
return to his basement lair to bang his
head against the walls over a discrepancy between what his boss had learned in
medical school and what he himself
had just seen under his microscope.
During my time at
the Palace, initially as a staff scientist and later as a lab chief in the brain biochemistry section,
the psychiatrists who were my bosses were
men I would describe as medical doctors with people skills. By temperament, they exuded a kind of charm
that, coupled with their keen insight into the human dynamic, allowed them, if
they so wished, to zoom up the professional ladder. In jest. I used to refer to
them collectively as the Slick Boys, because of their expensive suits, smooth manners, and elegant
office suites.
When I first
arrived at the Palace. I was glad to see that there were as many women as women passing
through the halls,
but I soon realized that most of them clearly belonged to the
technician class. Even today, few females ascend to alpha status, where tenure
is the prize, instead remaining down in the trenches, lowly serfs toiling away
at the donkey-work. The unspoken belief that women lacked the right kind of
mentality to do science because they were too emotional was a bias solidly in
place at the Palace.
But in spite of
the politically charged and socially stratified atmosphere, there was an
undeniable energy and excitement at the Palace, unique in all of science. This is bound to happen when the sharpest
minds are brought
together with nearly unlimited
resources, and the creative sparks are allowed to fly. In those days, something in the Palace air
called forth the very best from a
person.
LANDING
My first
year whizzed by, a blur of scrambling to get a lab set up, recruit
a staff of technicians and postdocs, perform experiments, and publish
papers. I quickly found out that my greatest challenges were less about science
than about learning to deal with the gigantic, overreaching bureaucracy and finding
a place in the complex
sociopolitical scene of Palace life. By the time I reached my first
anniversary, the overall feeling I had was one of pure, abject gratitude for
having survived.
I was very nervous
that first year,
unsure that I would be able to continue to be the “star” I had become under the tutelage
of my mentor. Sol. How much of my success had been due to his
support, and how much had I genuinely achieved on my own? While my new
colleagues received me positively, treating me somewhat like a prodigy from
whom much greatness was expected, still I was uncomfortable. One of the
seemingly trivial concerns that stemmed from this insecurity was about what clothes to wear to work. None of the standard
uniforms seemed quite right for me. The few women who were at my level in the
hierarchy were older and belonged to the science-nun generation—their uniform
was not mine. The younger women were mostly technicians or postdocs, and I knew
I had to distinguish myself from them if I was going to take any kind of
leadership role befitting my status. I conferred with another newly hired
female colleague: How could we dress comfortably, retain
a modicum of femininity,
and still be taken seriously by our fellow
scientists? Together, we came up with
a totally new style consisting of designer jeans topped off by a fashionable,
obviously pricey blouse.
But dress code
quickly became a subsidiary issue, replaced by what became my first Herculean labor—to secure a lab
in which I could begin to act like a scientist, I’d assumed when I’d accepted
the job at the Palace that a lab had already been designated for me. It was a
shock to find out I was expected to literally create one from nothing, as
territory was precious at the Palace, and, at any moment, there were scientists
stacked up like airplanes over JFK, waiting to land in a working lab. I was
told that work orders for my space had been written some time ago, but that the
renovations had not yet begun.
In time, I came to realize
that my situation was not unusual, and that most new scientists were expected to set
up their operations without a great deal of guidance. The implication was that now you were on your own, and the only cost of your freedom was the
initiative required to get your own projects rolling. It was a kind of Club Med for scientists, providing an
atmosphere totally insulated from
concerns about money, with a rare and incredible freedom to do what we came
here to do: pure, unadulterated research!
While I waited
for my lab, they parked me in an empty library room. I was able to push some tables
together to create
a makeshift bench,
but was stymied by the challenge of how to carry
out my experiments without access to any running water. My solution was to lug
my extremely heavy filter machine down the hall to the ladies’ room to empty it
whenever I had to do any filtering. Under these conditions, most of my early experiments
crashed, and in those first
months, I had some real moments of frustration and despair.
I found myself wandering up and down the halls
frequently during this period, checking out the labs of the Palace
bigwigs, the senior
scientists who were
internationally recognized leaders in their fields. I was thrilled to be
invited in occasionally for a
friendly chat, and to be treated by these top scientists as a colleague and
peer. I tried not to be too bothered by the fact that so few of them were
women, reassuring myself with naive idealism that science was truly a
meritocracy, and that it I produced good work and did great science, someday I’d rise to the top, too.
IN DECEMBER, my laboratory was ready, though
it was a far cry from the fancy labs I’d been visiting. The
office was so narrow that if I closed the door. I could barely fit a desk and
chairs for two people in it. Agu, who had also been in lab limbo for the past
four months, occupied an equally tiny office next to mine. Even though
we were hidden away at the far end of Hallway 2 North, Building
10.
we liked to think that together we generated a synergistic energy that
attracted the younger and more open-minded researchers in our
direction.
It was a
potentially fertile spot, our little corner of the Palace, where the boundaries
of two separate disciplines, Agu’s psychology and my neuropharmacology,
touched. Here there was a promise of the kind of interdisciplinary research
that was relatively rare in the compartmentalized environs of the rest of the
Palace. I could walk next door and tap into a worldview that focused on
behavior and even “mood,” a term used in experimental psychology that hinted at
“emotion” or “consciousness,” domains my own field was in no way comfortable
with. It was an arrangement that encouraged my bent toward collaboration and
boundary-crossing, as well as in my interest in the psyche, the mind.
INTRIGUE
I had been in my
new lab for only a few weeks when Les Iverson, a visiting English researcher
and one of Julie’s boys, dropped by for a visit. He brought with him the
groundbreaking paper that Hughes and Kosterlitz were about to publish—the one
described earlier in my lecture—where they revealed the chemical structure of
the mysterious peptide they had christened enkephalin.
This
was the same substance that Sol had isolated and was calling MLF, but for which he was unable to write the chemical
formula, even though he and his lab
were laboring
frantically to crack the code.
Les had been
given a preview copy of the paper because he was an advance reviewer, but of
course he wouldn’t let me see the contents, showing me only the tantalizing
title: “Isolation and chemical characterization of enkephalin—the brain’s own
morphine, a pair of pentapeptides.” I would have to wait, along with everyone
else, until the paper came out in the year-end issue of the prestigious British
journal Nature in December 1975.
Hughes, who had gotten a lot cagier since the Boston meeting, was
following a common strategy, which was to publish
at the very end of the year, thereby preventing any particularly facile
competitor from seeming
to scoop the discovery by publishing his own version in a different journal during the
same year. Any subsequent publications on the subject would bear a post-1975
date.
Iverson was
staying up the road a bit, a houseguest of Sol’s, and as soon as he left to
return to Baltimore, I trotted over to Agu’s office. I knew that once the
structure of the substance was revealed, there would be a rush to do the
confirmation experiments, and my lab, together with Agu’s, was perfectly set up to get a jump on this important phase of
the discovery. What I needed was to somehow get ahold of the chemical formula
for the structure as soon as possible, and then have a chemist manufacture the
substance for me so I could use it in an experiment that proved, yes, indeed,
that what Hughes had found was the real McCoy.
But we had to move fast. If everything went right, we’d submit our paper to the highly visible but
politically treacherous journal Science,
a risky choice because the old boys had a firm grip on the review process, and,
for political purposes, might choose to ignore our submission.
I placed a call
to my friend Dr. Jaw-Kang Chang, who, with his wife, Eng Tau, had just opened a
peptide “boutique” in the garage of his home near San Francisco. At that time,
they were the first of what would be many small commercial labs springing up
all around the country equipped with the machinery and manpower to manufacture
just about any kind of peptide in the growing field. Chang thought he could
find a leak from a secret source, and as soon
as he had it, he’d make
the peptides and send them to
me overnight.
It was a great
plan. Chang would make the peptides, and Agu and I would do the experiments.
Agu would prove that the peptide caused pain relief when dropped into the brain
at the analgesic site, the PAG, then I’d demonstrate how it blocked binding to
the opiate receptor in a test tube, just as we’d seen done with morphine and other synthetic
opiates tested in a similar
fashion. I hoped to bask in the reflected glory of the
enkephalin discovery reminding everyone of my
earlier contributions, and Agu would have a chance to show off his finely
honed
brain-injection
techniques, reminding everyone of his work showing how morphine acted in the PAG to relieve pain. Chang and his
partners would have a chance to put their start-up company on the map and
receive multitudes of orders for the synthetic version of this hot new
substance enkephalin, which was sure to be in global demand very soon.
But it didn’t work. At least not the way we planned.
The very next day Chang got the structure via a transatlantic phone call from a Chinese chemist in England who
teched in a commercial lab that Hughes had consulted, Working night and day
with all hands and machines on deck, Chang’s group produced two test tubes of
the enkephalins in less time than it took to mail the stuff from California to
my lab in Maryland. All this happened within forty- eight hours of our first
tip off that the paper revealing the structure was about to be published.
We ran the tests
and Eureka! It was the real thing, a substance identical to that made by the
brain, which acted just like the opiate drugs, blocking pain and binding to the
opiate receptor. Here was what everyone had been looking for— something that
chemists could manufacture for use as a harmless, nonaddicting painkiller. I quickly wrote up our results and mailed the manuscript to Science.
We
were disappointed but not surprised when they rejected it. In order to get it
printed as close on the heels of Hughes’s paper as possible, we repackaged it
and sent it out to the low-rent, quick-turnaround journal Life Sciences, where it was published in the late-January 1976
issue, one month after Hughes’s paper appeared in Nature.
Our timing had been good, but a competitor managed to get his paper into the more highly visible Nature, and, even though it appeared a
few months later than ours, it is his work, not ours, that today is cited for
the confirmation experiment that proved enkephalin was the body’s natural
opiate drug.
There was,
however, some poetic justice in the end. While not advancing our reputations as
planned, our research had led us to unearth a rather fishy discrepancy. We had noticed
that the enkephalin was as potent as morphine
in the cold test tube experiment, but surprisingly weak when dropped
directly into the brains of Agu’s rats. We surmised that it must be getting
chewed up and rendered inactive in the warm brain by enzymes that normally go to work at
body temperature. Once again working
with Chang, we designed and constructed an analog of enkephalin, replacing one amino acid. L-alanine, with its mirror-image amino acid,
D-alanine, thereby making a longer-lasting form of enkephalin, which was shown to be more resistant
to the enzyme’s action. This
time
our paper was accepted by Science,
where it appeared only a few months later, in September 1976.
We got plenty of
credit for that finding, more, in fact, than anyone bargained for. I presented
my “super enkephalin” at a meeting in Scotland that summer, which sent the
pharmaceutical company scientists in my audience dashing to the phones to call their labs and mobilize their companies’ patent lawyers. These giant biotech department stores had
been very busy manufacturing and testing all kinds of peptides for commercial
potential. Now they thought they had the Holy Grail, the natural-style
morphine, the nonaddictive painkiller (and possible antiaddiction drug), for
which the industry had been dolling out dollars for years in order to defray the
high costs of the fabulous Opiate Club meetings around the world.
Shortly after I
returned to the States, I was visited by a Justice Department lawyer who showed me how to write a patent before
“disclosing your invention,” as she diplomatically put it, implying
that I’d best not go shooting
off my mouth to a bunch of industry guys about an invention the NIH funded and owned—a little detail
I had never thought about.
A royal battle
ensued among ten pharmaceutical companies, each one claiming they had
the D-alanine enkephalin first. The resulting federal lawsuit, U.S. for Pert v. Burroughs Wellcome, etc., took several years of Justice Department
involvement, and in the end we won, but it was a Pyrrhic victory. The new
enkephalin turned out to be just as addictive as the original
one, and even more expensive to make at the
time, so it was of no use to the industry.
But back to the
early days of December 1975. After Les’s visit, but before Hughes’s paper hit the stands, word drifted down from Baltimore
that Sol and his lab had been able to crack
enkephalin’s structure. I knew that Sol had been working relentlessly with his
most aggressive postdoc, a hard-working Israeli named Rabi, but that they
hadn’t been able to get enough of the purified peptide out of the pig brains to run a reliable test. But now, apparently, they’d
done it.
The
very day after Les Iverson flew back to England, and around the same time John
Hughes sent Sol his Nature preprint,
Sol was reported to be racing up and down the hallways of Hopkins, waving a
long piece of data chartpaper, proudly exclaiming to all that he and Rabi bad
finally cracked the enkephalin formula. And, sure enough, there was the data,
with all the right amino-acid peaks. It was the same data they had produced
weeks ago, but at the time they’d
been unable to understand it. Now they were able to interpret it and call
it the real McCoy.
Too late to scoop Hughes, but eager to try to tie him, Sol and Rabi published
a
decent structural proof in the early January issue of Life Sciences, right before the issue in which we had published our
glory-mongering Science reject,
confirming the analgesic properties of enkephalin. But it was too little, too
late. Sol had run it up the flagpole, and no one had saluted. Ever the
politically savvy wheeler-dealer, Sol quickly distanced himself from any
appearance of trying to share credit with the Scottish research team for
revealing the chemical structure of
enkephalin. In the end, he even sent Kosterlitz, the senior man, a congratulatory case of Cognac. It was this
gesture, I was later to speculate, that laid the ground for the magic three to
move forward in unison to claim their future
prize.
ENDORPHIN HIGH
My immediate
superior in the early days at the Palace was Dr. William Bunney, head of the adult psychiatry branch and former director
of the National Institute of Drug Abuse, whom I had first met two years earlier
at the Hopkins press conference announcing the discovery of the opiate
receptor. Dr. Bunney occupied an opulent suite, furnished with furniture and
fine art he himself had purchased, a few floors above my lab. In a weekly
ritual, I would ascend to his spacious office and deliver the update on my
research projects. Dr. Bunney had a calm and clipped style that perfectly fit
the Hollywood image of the classic psychiatrist, and he listened
intently as I reeled off the week’s findings. He always wore a dark, pin-striped suit,
which, I imagined, was one of dozens of identical ones in his closet at home.
Biff, a nickname
I eventually felt comfortable using, had risen to his position within the
Palace hierarchy by showing that lithium was an effective drug for
manic-depressive psychosis. When I first arrived, he controlled a large corner
of the funding empire through the NIH’s National Institute of Drug Abuse, an
organization that had come into existence simultaneously with the opiate- receptor discovery. The purpose of NIDA
was to support research that it was hoped would one day
lead to the development of drugs to cure addiction.
Biff’s very first question took me by surprise. I was in his office
for my weekly report when he leaned forward, looked me straight in the eye, and
said in a flat,
dry voice, “Do you realize, Candace, that for a heroin addict the first intravenous
injection hits the brain like a sexual orgism?”
“Gosh, no, Dr. Bunney, I didn’t,”
I responded uncomfortably.
Biff explained
that he believed the pleasure experienced during orgasm was accompanied by a
surge of endorphins—the term that was being used to refer to Hughes’s
enkephalin—into the bloodstream. Now, that caught my attention, as did any idea that
might explain the influence of the opiates and how they worked to produce pleasure and relieve pain. Soon
I was designing a test that could measure levels of endorphins in the blood and
running a series of experiments to determine which kinds of behavior made these levels go up, and which
made them go down.
My investigation
of this question spanned a period of almost two years. We used hamsters for one
study, the classic lab animals for studying sexual behavior because of their predictable cycle of sexual behavior—two minutes
of licking this or that, three
minutes of humping, etc., and the act was complete. The males are extremely
prolific, ejaculating about twenty-three times per cycle. Later, we were joined
by Nancy Ostrowski, an accomplished scientist who had left behind her desire to
become a nun and gone on instead to become an expert on the brain mechanisms of
animal sex. Nancy would inject the animals with a radioactive opiate before
copulation, and then, at various points in the cycle, decapitate them and
remove the brains. Using auto-radiographic visualization of the animals’
brains, the two of us were able to see where endorphins were released during
orgasm, and in what quantity. We found that blood endorphin
levels increased by about 200
percent from the beginning to the end of the sex act.
With our
newfound method of measuring endorphins in the blood, all kinds of other
projects were now possible. We explored the question of how exercise affected
the release of endorphins when I recruited twelve young Palace psychiatrists
who were serious runners to let us take blood samples before and after their daily runs. The results showed
a definite increase in endorphin levels, but the assay crashed at a few key
moments, causing us to lose the precious samples that my subjects
had literally sweated
to produce. Nothing
much came of these
studies until Peter
Farell, an exercise
physiologist from outside
the Palace, pulled a paper together that made use of my expertise, but
was based mostly on his own efforts.
He generously made me a coauthor of the paper, which was the first published
study to provide the physiological validation of the phenomenon we now know as
“runners’ high.”
My next project
was the obvious biggie, the human-orgasm experiment, which presented a challenge in both recruitment and design.
Since it wasn’t possible to have a technician present to draw blood at the
ultimate moment, we had to settle for measuring the endorphins in our subjects’
saliva. Our subjects consisted of friends,
as well as Agu and me, all of us agreeing to chew parafilm
(which
generates saliva) at various moments during sexual intercourse and then to spit into a test tube.
While enjoyable
to do, these experiments were ultimately considered failures from a Palace
point of view, because the results, suggestive as they were, lacked sufficient clarity
to be written up and accepted by a medical
journal. The work did
produce a number of very interesting abstracts, which were presented
at some early neuroscience meetings and were, understandably, very
popular. But the
idea that human orgasm is accompanied by the release of the organism’s own
pleasure chemicals has never quite
seen the light
of day in a prestigious journal.
SUCCESS
And so it goes,
month after month, planning experiments, brainstorming with your postdocs, and
gathering data with an eye to publication. I was usually a pushover when it
came to believing that data. If it looked crisp, and if, after massaging it
this way and that, my gut reaction was still affirmative, I’d give the green
light for a paper to be prepared. Most lab chiefs were just the opposite,
making their postdocs repeat experiments ad nauseam, terrified of attributing truth to something
that turns out to be a trick of the numbers, or an artifact—an error created by
the method, which leads to a false conclusion.
But when the
data held true, and it looked like we’d uncovered a legitimate piece of the
picture, then we’d move ahead to getting it in print. As I said earlier, we scientists measure our success
in terms of papers—how many we’ve
published and where they’ve appeared, in journals considered top of the line,
middle of the list, or bottom of the barrel.
That, in a nutshell, is what scientific life is all about.
The pay is comfortable but not spectacular, and the only real
glory comes from seeing your name in print under the title of a paper. Even
more thrilling, at times, is seeing your work cited in another scientist’s
paper, which is significant because it affects your status in the professional
hierarchy. Your position is determined by a huge database called the “citation
index,” a listing of every paper that has ever been referred to in another paper,
ranking each paper according to the number of times it has been cited. For many
years Sol has been the very top-cited
scientist in hiomedicine! For one ten-year period, my ranking was 130 among the
most highly cited scientists in the world.
The percentage
of papers that get cited more than a few times is very small,
and for this reason everyone always refers to their
own previous papers as much as is practically possible. Because
appearing in print is so important, and because modern scientific projects can
involve several collaborators, more bitter and
intense arguments arise over the order of authorship on a paper than
over the thorniest of theoretical issues. As was the case with the opiate-receptor paper that Sol and I published, the first author
cited is generally the person who took
the lead in designing and implementing the experiment. Then come the names,
in descending order of importance, of all those who participated, either by advising or assisting, sometimes as many as ten or fifteen names.
The last name to be mentioned is the person who
either runs the lab or has raised the money to make it all happen.
Traditionally, the names of the technicians who do all the actual lifting and hauling are left off of
papers, but I always thought it was the decent thing to do to include them on
my papers. I was also glad to let my postdocs take the first-place position, specially if the paper was an important
one. I had learned from my work with the opiate receptor
that first authorship on a key paper could go a long way toward assuring a person’s
career.
It was this name
game that was partially responsible for my own swift rise to the top, and would
soon be a pivotal element in an unfolding drama that would completely change
the course of my career.
In a prophetic
glimpse of things to come, John Hughes had dropped by my house for a casual
visit in the spring of ’78. As we sat out on the back deck sipping cool drinks,
he turned toward me and asked rather abruptly, “Candace, have you ever heard
about an award called the Lasker?”
“No.” I responded. “What’s it for?”
“Well, it’s
kind of an American Nobel Prize, given each year to scientists who have done
outstanding medical research,” Hughes explained. “In fact, the scientists who
receive it usually go on to win the Nobel. It’s sort of a stepping stone.”
Now he had my
attention. I knew the Nobel was the biggest prize in science, but I hadn’t a
clue as to how the scientists who won it were selected.
“What if I told
you that Hans, Sol, and I were about to receive this year’s Lasker for the
opiate work?” John asked.
It took a moment
for his words to register, but when they did, I blurted. “You’ve got to be
kidding, John! And leave me out? Why, I’d be furious, of course!”
6 BREAKING
THE RULES
INVITATION
Science in the big
leagues is a lot like what goes on up at the basket at the NBA play-offs: very competitive, with
sharp knees and elbows flying hard and fast. As individuals vie fiercely for
credit, everyone knows you have to take care of yourself, because no one else will.
The exception, of course, is your scientific family, your collaborators, whose job it is to watch out for you, scratch your hack, and see that you get a chance
at the basket when it’s your turn.
While I found the
game thrilling to play, I had not been sufficiently conditioned to accept the code of loyalty
that it demanded. In a series of events that
caused me much heartbreak and earned me much notoriety, I broke the rules and
was dealt the cruelest of punishments, alienation from my scientific family.
Later, in a popular book entitled Apprentice
to Genius, Robert Kanigel would make
a dramatic case for how I’d embarrassed a most royal medical dynasty, although this had never been my intention. In retrospect, I can see how my actions were part of a greater force
at work to bring about a major shift from old- boy rule to a more egalitarian
system.
It all began in the fall of 1978,
when Sol Snyder, John Hughes, and Hans Kosterlitz were recognized for their
opiate receptor/endorphin research and received a prize nearly as prestigious
as the Nobel, the Lasker Award. My name wasn’t mentioned.
John Hughes had
tried to tip me off when he paid a friendly visit to my home the summer before
the awards ceremony in October.
But I was so stunned when he
mentioned that the Lasker might
he given to him and the other
researchers, that I blocked all further conversation on the topic.
Later, I realized that John had tried to alert me to what was already in the
works, so that if I had wanted to do something about it. I still had time, But
I was so naive politically that I chose to stick my head in the sand and reject
the possibility that such a scenario would ever take place.
I didn’t give it
another thought until some months later, when I got a phone call from Sol,
inviting me to a luncheon in New York City.
“Hello, my little baby girl,” he cooed affectionately, with the usual politically
incorrect
term of endearment I had tolerated with mixed pleasure and horror for nearly
seven years. We chatted brieftly, and then he announced, an audible tension coming into his voice, “Candace.
I’m receiving an award in New York City next month, and I want you to be one of
the live invited guests I’m allowed to
bring.”
Although I’d
been away from Hopkins for over a year, I was still flush with gratitude for Sol’s help in procuring for me a lab and a position
as staff scientist at NIH. and I was thrilled that
he would think to invite me to this obviously important event. He then
mentioned that two other scientists were receiving the award with him, but failed to mention what it was for or who the other two were.
I hung up
feeling pleased, but in the back of my mind an uneasy question surfaced. Sol
had been unmistakably uneasy in extending this invitation, and I wondered why
the Golden Boy, the wunderkind of neuroscience, would be afraid of asking his former graduate student to a luncheon where
he’d be receiving an award? It took only a few seconds for the answer to hit me
square between the eyes. The Lasker Award! The one John Hughes had talked
about! This is what he’d meant, that he and Kosterlitz were to join Sol in
receiving the Lasker Award for the opiate receptor and endorphin findings, the
very work I had played such a pivotal
role in. And now Sol was inviting me to the awards luncheon as his guest!
My heart had
already begun to pump furiously, even before my brain got the full news. I
picked up the phone and dialed Sol back.
“Sol.” I said,
barely concealing my anger, “do I understand that you, Hughes, and Kosterlitz
are accepting an award for our work on the opiate receptor, and I’m not included?”
Taken off guard
by my rawness, he admitted, half-apologetically, that, yes, it did seem
strange, but that’s how these awards things went, they were unpredictable, not
always going to the person you’d expect. And anyway, he assured me, it was too
late to do anything about it now. To make it up to me, he would see that I
stood up for a bow at the awards luncheon, which he thought I would enjoy, he
told me, since Ted Kennedy would be presiding over the ceremonies at the famed
Rainbow Room, and I’d have a chance
to meet him.
I hung up again,
and tried to see things from Sol’s point of view, but I could not put my rage
to rest. The idea that I would be sitting in the audience while he and the others were honored for the work that I had played such an important part in seemed blatantly
unfair. Was I really expected to stand down for my part in what had turned out to be a tremendous discovery, one that in
the few short years since it occurred had been reshaping
the entire field of the neurosciences?
No,
I resolved, this was not something I could watch happen. But what could I do?
DEEPER ISSUE
At the time all
this took place. I had been reading several books that greatly influenced the development of my thinking
and feeling. They were biographies of Rosalind Franklin, the
brilliant scientist who had provided the critical link in the chain of
reasoning that allowed Francis Crick and John Watson to show that the DNA
structure was a double helix. As a result, the two men beat Linus Pauling to the punch and bagged themselves
a Nobel in 1962. Franklin was a classic science nun whose life was totally
given over to her work, and in Watson’s
book. The Double Helix, we get to see
how these women were viewed by their male colleagues. The contempt all but
bleeds through the pages, as Watson justifies his and Crick’s actions in a
graphic example of unabashed sexism
in science.
But the truth of the matter is, the two men visited Franklin’s lab when she was out of town and persuaded her boss
to let them take a peek at her data. In what
must have been a moment of incredible rationalizing, they stole Franklin’s
findings and got away clean, tossing her a bone of acknowledgment in their
seminal paper, which won them the biggest award in science. In his best-selling
book, Watson actually boasts about the theft, deriding their colleague for
withholding her findings for publication in her own paper, which came out in
the same journal—Nature—where theirs had appeared just a few months later.
At the time, no reviewer, to my knowledge, cried foul, although in later
Years some heroic attempts at correcting the record were made.
To say I was
livid about Rosalind Franklins plight is an understatement. Even more, the tale
of this outrageous deception deepened my appreciation for all the women who had been my teachers.
I no longer saw them as second-class scientists who had failed to achieve
status as lab chiefs and had settled
instead for academia. I now realized
that they were the pioneers
who, if I were ever to
run a big lab. I could thank for trailblazing the way, enduring the rampant
sexism of their male colleagues in order to level the playing field
for future generations of women in science.
But even while I acknowledged the debt I owed to these women, I was
appalled
at how little had changed since their time. The deeply ingrained bias against
women surfaced often at meetings, especially at the quarterly study section,
where we would review grant
applications. Whenever my male colleagues came across a grant whose
principal investigator the “PI,” as we call the
controller of the government green was a woman, they would unfailingly amuse
themselves by subtly conjuring up an image of the eccentric, asexual lady
scientist. This was followed by a silent consensus concerning her scientific
untrustworthiness, an assumption that reverberated around the conference table
until, finally, the application was given an inappropriately low rating. Most
interesting was the discussion about the budget section of these
female-initiated grants. While grants with a male PI requesting twelve postdocs
never raised an eyebrow, the grants with a woman PI asking for a secretary and
extra technicians would be chewed over ad nauseam. Like the attack cry of a
flock of ravenous birds, the word she was repeated incessantly during the
deliberations—Why couldn’t she manage
with less? I once amused myself by scientifically documenting this male pack
behavior, carefully marking the number of times the pronoun was mentioned
during one long afternoon session. My record showed that “she” was used nine times more often than “he,” in spite of the fact that
grants involving female PI’s were rarer by far than their male-headlined
counterparts. In as humorous a way as possible. I would try to point out the
subconscious prejudice, but my words tell on deaf ears.
These, then,
were the thoughts and feelings that were occupying my attention when the
challenge of the Lasker landed in my lap. I woke up one morning and looked in the
mirror—only to find Rosalind Franklin
looking back at me.
Whereupon I took to the phone and solicited
all my friends for advice.
Almost to a person,
each advised me to shut up and stay put. “That’s just the
way the game is played,” I heard over and over again. And certainly that’s the way Rosalind Franklin had handled it. She
let Watson and Crick swipe her piece of the biggest
scientific discovery of the century
without so much as a peep. I was sure her friends told her the same
things mine were telling me: Be careful— if
you upset the boys, they might
not let you play with them
anymore.
The more I thought
about it, the more angry I became.
Was I expected to shove my feelings deep down inside
me, where they might fester
for years, eating at me and eroding my self-respect, my sense of pride and accomplishment, my self-esteem? I
knew that I had to take my chances and blow the whistle or spend the rest of my
life cringing with resentment and disappointment whenever the subject
of the opiate receptor came up, every time
Sol’s name was mentioned
in connection with the discovery
and mine was not.
In my reading, I had learned that
a few years after the theft of her data, Rosalind
Franklin died of cancer. Even then, when almost no one had done and serious
work on the possible effects of the emotions on health, I believed that her
disease had been exacerbated by the humiliation she suffered at the hands
of these, and probably
many other, old boys, and that her failure to express her anger contributed to and possibly
caused her death. It was partly intuition and partly common sense, but I felt that by not speaking
up, I would be sacrificing my self-esteem and
self-respect, not to mention possibly setting myself up for a nice case of
depression and maybe a cancer or two down the line.
I certainly had
no intention of allowing this to happen, and neither could I see myself going
to the awards luncheon in order to “take a bow,” especially when I learned that Avram Goldstein
and Eric Simon had also been invited
and would be acknowledged
equally for their contributions. This was too bitter a pill to swallow, to have to stand alongside
those who had failed to go the full nine yards, when I was the one who had
done the brain-breaking work to put the cap on
the opiate-receptor search, and had done it despite the abandonment of the
research by a man who was now accepting the award for it. No. I told myself, I
couldn’t let this happen, to be forgotten and ignored by history, while the
boys waltzed away with the prize.
DEFENSE
When the official
invitation to the Lasker luncheon arrived. I knew I could never accept. I
decided to tell the truth.
“Dear Mrs.
Lasker.” my letter began. “I make it a point never to tell white lies
concerning social occasions. Therefore. I want you to know that the reason I
will not be attending your luncheon is that I’m upset and angered at being
excluded from this year’s Lasker Award for research I conducted in
collaboration with Dr. Sol Snyder. So often women and other people who are low
on the scientific hierarchy are excluded from receiving recognition for work
which in truth they did, while the senior male scientist on the project is rewarded in their
place.”
That was the
first statement about the incident. The second and much more public one was the
result of a copy of that letter my husband Agu mailed to jean Marx, an editor
at Science magazine. Agu was even
angrier than I was. Being male, he knew that the boys played
a nasty game, and that that I let myself be
shuffled
out of the spotlight, no one was going to come to my rescue. While I was
practically debilitated by my anger and confusion. Agu didn’t think twice about
shoving a stick in the spokes of the scientific wheels as they spun on. He
dropped the letter in the mailbox, and life went on.
I never spoke personally
with Jean Marx, but the letter caught her attention, especially the part about
women being routinely excluded from scientific prizes. Her journalists eye had
picked up on the larger issue of scientific credit, and certainly the
Pert-Snyder Lasker flap was a guaranteed hook for her readership. Her lead
editorial in the very visible Science magazine.
“Lasker Award Stirs Controversy,” appeared in January 1979, complete with a large picture of me
that the NIH had conveniently provided while I was at a conference out of town.
My fear of being forgotten
was instantly replaced by a
feeling of pure fear.
The history of
science is full of tales about feuds over who deserved credit for what. One classic brouhaha
had erupted right in own scientific family,
when Julie Axelrod broke with his mentor, Steve Brodie, over the
microsomal enzyme discovery. Brodie, the senior man at the time, tried to
monopolize the research, and Julie, the
underdog, had refused to lie down
and roll over. But more typically,. the scenario is that
the junior man puts up with the injustices in the hopes that someday he’ll be
on the top.
When reporters
from various scientific publications questioned Sol in the days
fallowing the Science editorial, he claimed that he had contacted members of the Awards Committee and asked
them to include me in the award. He readily confirmed my written statement to
Mary Lasker that I had indeed played a key role
in both initiating and following up the research. But that was as far as he
would go. In the month-long interval between Sol’s telling me about the award and the actual ceremony, I called him
repeatedly to ask him to make a statement on
my behalf—either to the Lasker committee itself, requesting that they include
me in the award, or at the ceremony when he went up to accept the award. Sol
refused. In a last-ditch attempt to salvage something from the situation. I
asked if he would at least agree
to donate half the prize
money (which I’ve since heard was quite modest, perhaps
as little as $15,000) to a Bryn Mawr scholarship in my name. To this, too, the answer was no.
Meanwhile, word
of my plight was picked up by Joan Arehart-Treichel, a biomedicine editor at Science News who had followed the field
of peptides and receptors closely. In her February 1979 article about the
Lasker flap, she stated her initial view that I had been excluded from the
award because only three scientists could be nominated for the Nobel. She
wrote: “I found myself
outraged
when America’s most prestigious medical award, the Lasker, was handed out in the brain peptide-opiate
field to only three of the four scientists whom I had expected to receive it.
The three who were acclaimed were men; the one who was excluded was a woman.”
Assuming it was
the numbers that were the cause of my exclusion, Arehart- Treichel went on to
say that her investigation had revealed a deeper, perhaps nastier truth. The
reason I had been passed over was because no one had considered putting my name
up for nomination. Neither Sol nor any of his buddies had ever mentioned my name as someone
involved in the discovery. My displeasure at not being included, it seemed, had
come as a total shock to the Awards Committee. “Pert? Who’s she?” they
responded when the editor called each of the committee members
individually. When she pointed out that Pert was the name of the first author on
the opiate-receptor paper, they squirmed uncomfortably, and they were further chagrined
when she mentioned
that Hughes, in a directly analogous situation, had been the first
author on the endorphin paper. The article ended on a speculation about whether
it was still possible for me to receive a Nobel far my opiate work.
“I’m not very
optimistic,” she wrote, “since the same informal roster of predominantly male scientists, sometimes
referred to as the ‘old boys club,’ seems to he responsible for
nominating; scientists for both the Lasker Award and the Nobel Prize in
Medicine….”
Also appearing
in print at the time were the comments of Eugene Garfield of the Institute of
Scientific Information an organization that ranks scientists according to how
often peers have cited their papers. Garfield had developed ways to interpret
this citation data to give a sense of a particular research dynamic.
“Since the
Lasker committee deliberations are confidential,” he wrote in his article, “we
do not know if the members used citation data.” He then went on to identity
seven other scientists whose early work on the opiate receptor was well
documented in the literature. His recounting of my work served as a summation
of my entire scientific career up to that time:
From 1973
to 1976. Pert and Snyder co-authored 17 journal articles on opiate receptors.
These papers have received to date an average
of 87 citations per article.
During the same period, Snyder and other collaborators published
23 papers in the opiate receptor field. These papers have received an average
of 37.5 citations per
article. Of
Snyder’s papers on opiate receptors. Pert co-authored five of the six which received
over 100 citations. She co-authored 10
of his 20 most-cited opiate receptor papers. Since leaving Snyder’s lab. Pert
has published 18 article’s. Seven of them appeared in 1978 and have had
relatively little time to receive citations. Yet these is papers have received
over 300 citations, or an average of about 16 citations per paper. And one of
her 1976 papers the discovery of the long-lasting enkephalin analog with
D-alanine that started a pharmaceutical stampede proved to be among the one
hundred papers most cited in 1976-1977. Thus.
Pert’s work at NIMH continues to be significant to her colleagues
….
Garfield’s
meticulous analysis settled the most persistent argument used against me, that
as a graduate student I’d only carried out the orders of a senior scientist,
and had done nothing on my own worthy of a mention since leaving my mentor. This attempt at exoneration
made me feel better, but in the bigger picture. I soon realized, the major
damage couldn’t be undone. By involving journalists in what should have been a
private spat within my own scientific family. I’d stepped too far over the
line.
BETRAYAL
A few weeks
after the first wave of publicity had passed, Julie Axelrod called me into his
office. Still not realizing the impact of what I had done, I half- expected to be given a special project or
other favor—after all, he’d been so positive and enthusiastic in his
recruitment of me to my NIH post. Instead, Julie asked me to help him fill out
the form he was submitting to nominate Snyder, Hughes, and Kosterlitz for the
Nobel Prize. He hinted that my cooperation would go a long way toward soothing
the bad feelings that still lingered as a result
of the Lasker publicity. And, of course, he emphasized, I must know that
the committee that made the final selections for the Nobel Prize hated any kind
of scandal.
Without any
hesitation. I shook my head and flatly refused, Julie’s mouth dropped open.
“You’ve got to
do this. You’re the only one who knows everything that happened,” he pleaded.
“Exactly,” I
responded, “and it’s precisely because I know everything that I can’t do it.”
“Don’t you love Sol?” he insisted,
his voice rising.
“Why are you doing this?
You help him now and he’ll help you later. This is the way it works. How
old are you anyway? C’mon, you’re a nice girl, Candace …”
He was shouting at me when I stood up to leave.
Unquestionably, Julie was correct
about one thing: That’s the way it works,
the game of scientific recognition. If I helped Sol now, he’d help me later. And if I didn’t, well, I would soon learn what
would happen then.
Partly it was my
still-raw anger that kept me from having any broader perspective, and partly it
was a new heat arising in me from a recent revelation. During my own private
probing of the Lasker nomination process, I’d learned a shocking piece of
information from two highly reliable sources inside Sol’s lab. Evidently, Sol
had been officially nominated by the chairman of the pharmacology department at Hopkins along with Hughes and
Kosterlitz, but the forms had been seen on the desk of Sol’s secretary, being
typed according to his instructions. I now knew that Sol had prepared the
nomination documents himself, intentionally leaving my name off them. Perhaps there was not nefarious going on than that the
chairman, a new appointee at Hopkins, had told Sol to fill in the specifics,
trusting he would know the names of those involved and the details of the actual work. But knowing Sol’s love of
applying for grants and awards that promised a fabulous prize. I chose to believe
that he had initiated the nomination process and then sent the forms along to the chairman
for a signature, so that the chairman would appear to be the source of the nomination.
This, then, if
true, was the final twist of the knife. Was it possible that Sol had been
blaming the Awards Committee for my exclusion when he himself had cut me out? Had he counted on my devotion, on
the eager-to-please, self-sacrificing temperament I had displayed as his
apprentice, to get me to go along with his plan? I was convinced this was the ease. No male, regardless of status, would ever have accepted the situation,
but because I was a woman, Sol had taken a chance. In my bitterness. I vowed to put behind me all traces of the naive female
I had once been. Sol’s “baby girl.”
I exited Julie’s
office in tears, his angry, demanding voice reverberating in my ears as I slinked miserably along the Palace corridors to my office. Once
there.
I closed the door slumped to my desk, and released my feelings in several deep sobs. By now I felt my defeat was complete. Pulling myself together. I called Dr. Bunney
my immediate boss,
who descended from his office
to meet me in my tiny
cubicle—the first, last, and only time he ever made that particular journey.
Sitting across from me, so close our knees were almost touching, he listened in silence to my mixture
of grief and rage. “The truth is. I did ninety-
nine percent of the actual scientific work on the opiate receptor, both
inspiration and perspiration, even though Sol got the grant, slipped
me Goldstein’s original, if wrong, paper, and counseled
me when the going got tough,” I complained tearfully. “But when it came down to
it, he pulled the ping and ordered the entire project closed down, kaput! I
took a chance and continned, behind his back, because I believed it could be
done. Oh, I really do love Sol!” I wailed on, while Biff practiced his best
listening technique, and handed me a Kleenex.
Biff reminded me
that no lab chief at the Palace would ever let me become so closely associated
with such an important discover, as Sol had done. A Palace Slick Boy would have
seen the discovery for what it was and cut me out mercilessly, regardless of my
contribution, as soon as it surfaced for publication. But the bitter irony was
that by letting me be first author on the paper reporting our findings and then sending me on the
road to present them for all to see, Sol had assured
my career when I was only a graduate student—and assured himself a huge
heartache by losing maybe his only shot at the Big One, the Nobel.
When I calmed down,
Biff looked directly at me and said, “Do you realize now how important you are?
If you don’t sign off on this nomination for the Nobel and smooth over the Lusker
controversy, it’ll cost them all the prize.”
I was beginning
to understand what was going on. Biff later showed me a copy of Nobel’s will, which stipulated that only three living
scientists could win the prize at any one time. Someone had to be axed, and Sol
had expected, again, that I would take the fall gracefully. I realized that my
support, in spite of my earlier attempt to blow their ewer, was their last hope for the Nobel, making me a potential and very important
conspirator in their plan. But even then, I
wouldn’t budge.
Moving quickly,
and unbeknownst to me. Biff drafted a statement nominating me for the Nobel,
along with Sol and Lars Terenius, whose brief paper in an obscure Scandinavian
journal had reported findings parallel to our own, but in so densely technical
a fashion, and with so little fanfare, that it had gone almost unnoticed. I can only surmise the effect this had on the nominating committee, no doubt confusing
them to the breaking point, since Sol’s name also appeared
as part of a different trio in a separate nomination.
While a large percentage of Lasker recipients do go on to win the Nobel Prize. Snyder, Kosterlitz, and
Hughes did not get that year’s prize. After a long and reportedly heated
debate, the 1979 Nobel was handed out to a completely different trio of male
scientists for another discovery altogether. Within the cozy world of the
Palace, word spread rapidly that my uprising had cost them the Nobel. And
perhaps it had.
SURVIVAL
As a result of the Lasker flap, I developed a somewhat notorious
reputation.
Some
of my closer friends would jokingly introduce me at meetings as “the scarlet woman of neuroscience.” in an
attempt to make light of what they saw as an overreaction by others. But it was
not amusing when people I barely knew, senior male scientists, would cautiously
move to one side of the corridor when they saw me coming. The rumors, as is typical
in these kinds
of affairs, were they far worse than the actual
incidents, and many people had the illusion that I had called a major press
conference to publicly deny Sol’s role in the opiate- receptor discovery. I hadn’t,
of course, but people chose to believe in such a dramatic and lubricated
scenario for their own reasons.
Even more upsetting than the gossip
and the shuming
was the blackballing that went on in regard to important meetings and
forums. My imitations plummeted. I was no longer
asked to address
my colleagues at the top-of-the- line symposia, and was now
lucky to receive even the most peripheral spot at the low-rent affairs. Mv
response was to accept whatever came my way hoping that by doing so I would be able to hold on to some of my previous
visibility I was determined not to disappear.
The reality of my
new in-house status was painfully driven home when the Palace hosted a widely
publicized opiate meeting later in 1979. Hughes and Kosterlitz were flown in
from Scotland to headline the event, and Sol and other Opiate club members were
invited to present. For some unspoken reason, the organizers were unable to
find a spot on the roster for me to report on my new work at the NIH, and to
add insult to injury more than a few subtle suggestions were made that I not
attend. But I went anyway, my heart in my mouth, and endured the chilly
reception that greeted me.
This was a
period of time when whatever I did seemed to send sparks flying and start fires. One day, I decided to liven up my drab, institutional workspace
by
painting a brightly colored rainbow strip along the walls and out into the
hallway. I’d had a fondness for rainbows ever since my days at Hopkins when I
had surprised my labmates by painting my fingernails with the tiny multihued
crescents. To me, the rainbow was a profoundly hopeful symbol, separating the
white light of appearances into its multiple spectrum and revealing a hidden
dimension. It reminded me of my belief that it was the mission of, science to pierce through the layers of everyday
reality and penetrate to the truth. But to my colleagues, this innocent
exercise of right-brain expression made it seem as if I were trying to drive a
stake through the very heart of modern science. Main of them were simply
embarrassed, and in spite of the coutinued productivity of my lab, my
reputation as an eccentric grew.
As a survival
strategy, I garnered the support of two important allies—other women
scientists, who were growing force in research circles, and the media, as
represented by a never-ending supply of journalists who knew a good story when
they saw one.
After decades of
sexism that had never been honestly confronted until recently, my female colleagues hailed me as a heroine for standing up to the alpha male scientists. Even though I’d
lost, they recognized my courage in making an attempt to see that justice was done. In the early eighties, I joined
with a number of other female neuroscientists to start an organization called WIN, Women
in Neuroscience. We selected as our motto “WIN with Brains”
and posted an announcement in the Palace’s
women’s rooms stating
our intention that at the next Society of Neuroscience meeting, WIN
would convene its own symposium. Much to our amazement, about three hundred
women showed up for an event that
turned out to he part group therapy session, part serious scientific meeting.
It began in a spirit of lighthearted camaraderie, everyone happy to be in the
company of women and for once not made to feel
like outsiders at the boys’
clubhouse. I gave my lecture
barefoot, and, since
I was pregnant at the time (with my third child, Brandon), wore a wildly
colored hippie gown. But underneath the laughs and good time, there was an
undercurrent of anger so strong that we could do nothing but ride it for many
hours. So we steamed and vented, raged and wept, sharing horror story after horror story. And even though I knew
firsthand how tough it was to be a woman in
science, I was completely overwhelmed by what I heard.
The purpose of
WIN, as it evolved, became increasingly political. By organizing ourselves in
this way, we women were attempting to change our status from that of an oppressed minority to that of a modest interest group. We
intended
to lobby for more women to serve as chairs of our professional meetings, as well as set up a system of
mentorship so that the more successful could assist the less successful to
learn the ropes of grant-writing and political maneuvering. My involvement with
WIN wits very healing, even energizing for me at this time. I enjoyed being in
a position of leadership, and I liked making waves that rocked the boats of the power boys and their established structures.
While this was
going on, the media continued to sniff around, hoping to more fully exploit the
Lasker incident and catch up on my latest exploits. But I responded by throwing
them a curve, saying the Lasker was “old business,” and offering them instead
my views on the sorry plight of women in science, as well as the exciting discoveries that were
happening almost daily in neuroscience laboratories around the world. Over
time, I grew to like the press and came to consider journalists my allies in
what was turning out to be a personal battle to rescue my former reputation us
a promising young scientist—a Golden Girl— who
had done sonic great science, and was yet to do more.
In retrospect, I’m amazed at how brazenly
I dealt with the press,
often throwing caution to the winds and saying
whatever was on my mind at the time.
I hadn’t vet learned that I could demand that my quotes be read back to me, and so made some real blunders I later
regretted, especially when I was giving a lecture
and journalists reported my words as part of the public record. In a most
egregious example. I was once quoted us saying: “Don’t get me wrong. I like
men—but in their place, which is the bedroom. Let them out, and they start
wars.” In context—though I have long since forgotten what the context was—the
words seemed appropriate, but out of context
and in print, where I never
expected to see them, they looked outrageous. Unfortunately, it’s a quote that has followed me around like a
faithful puppy dog ever since.
It took a while to develop
an effective media filter, but eventually I grew
savvy enough to be able to bundle myself in a way that didn’t cause a
sensation. And once I got over the need to use the media to give voice to my
plight. I began to see that they could also help me communicate with the public
about the science I was
doing—which would ultimately be much more helpful to both my reputation and my
work.
Still, in spite
of the outlets that I cultivated with women and the media, the rejection I
experienced from my colleagues hurt tremendously. But like all assaults on the
organism that don’t destroy it, the injury turned out to be beneficial in the
long run. My faith in science as a search for truth was only strengthened as I
became more determined than ever to work hard and do great science. The single-mindedness of my focus on work was reinforced, ironically
enough,
by a near-screeching halt in my advance up the Palace hierarchy alter the
Lasker incident, a trend that kept me in the lab and close to
the bench.
Usually,
as scientists rise to power, their political skills become more finely honed than their scientific ones, causing
them to lose the intuitive feel that good experimentation requires. I was
spared this trade-off at a time when the bench
was the very best place for me to be.
By 1982 the
storm had passed, and I had emerged once again as a scientist whose reputation
was based more on productivity and significant advances than on rumors, prejudice, and ignorance. I had
learned to put my bitterness behind me.
But never again would I be the starry-eyed Bryn Mawr girl seeing the world
through rose-colored glasses
fixed firmly on her nose. Most of my illusions about the romance of science
had been stripped away, and I was left with some hard personal choices. Would I
continue to try and beat the boys at their game, becoming more aggressive, more
competitive, and more ruthless as I ascended the ladder to success?
Was I going to let myself be motivated to do science for the fame and status, maybe
even the money? In my heart of hearts, I knew that the only payment the fast track would bring
me was a migraine at the end of the day, or perhaps a coronary bypass before
the age of fifty.
DOING THE WORK
During the early
days of the neuropeptide explosion, when new brain chemicals were being
discovered every month, the field was so hot, so terribly fashionable, and so
productive that even after my disgrace I did not have to shape my lab’s work along pragmatic lines
dictated by economics or changing science trends. Instead, during the late
1970s we were able to follow our own inspirations, striking out in directions where
the work was assuredly doable, yet without having any real global perspective
to guide our work. Only later would the bigger picture emerge, and our efforts
be seen as contributing to advances that
were not even thought of as yet.
My lab, like most in the Palace, hummed with activity
night and day. By 1978 I was co-supervising, along with John
Tallman, a staff of up to ten and getting a taste of what it meant to be in
charge of the hiring and firing, the managing of people as well as resources
and projects. In the beginning, I had a personal preference for hiring Italian
graduate students and postdocs. I felt that their warmth, spontaneity, and lust
for life infused an element of fun as well as
creativity
into the lab atmosphere. They liked to come into the lab around two in the
afternoon and work all night, often peaking in rhythm around the time the
evening news came on.
But I never
developed any of the rigid rules about hiring staff that most of my colleagues did. Most of the time, I relied
on my gut feelings about
people, sensing an intuitive
connection before I made my decision to hire, and so
creating quite a bit of diversity in my lab.
As might be
expected, my lab had a much higher female quotient than other labs in the Palace.
Quite often, I hired brilliant
women, some at the level of
senior scientist, who were unable to find positions that matched their experience.
I remember one refugee from a lab on Long Island renowned
for its sexist policies who had invented
a technique to visualize a single neuron,
making it light up with
monoclonal antibodies. It was a revolutionary technique, one that should have
skyrocketed this woman’s career, but, instead. I found her knocking on my door like a beggar,
asking to work in my lab on a temporary
basis until she could find
other work.
Sometimes, a
postdoe would arrive with his or her own salary line from a grant, as was the case with my very first
postdoc, Terry Moody, a long-haired. California tennis jock. When Terry arrived
in my lab in 1977. I had a project ready and waiting for him. Just recently I had acquired a sample
of the bombesin peptide from Man in Brown, a California neuroscientist with whom I’d waited out a plane delay one stormy day in
Atlanta. Marvin told me he’d injected bombesin, which had been extracted from
the skin of a frog known as bombix
bombina, into rats, and it caused them to scratch furiously while losing
ten degrees in
body temperature. As it later turned out, itching and lower body temperature
were found to be among the effects in humans as well. Of course, it had to have
receptors in the brain, which Terry and I set out to find. Using the same
approach I had devised to find the opiate receptor. Terry was able to locate
bombesin receptors in the limbic areas of the rat brain. He and a number of
other postdocs were responsible for a string of such discoveries, which kept us
all in a perpetual state of excitement.
Typically, a
Palace lab duel might supervise anywhere from ten to thirty postdocs, each one
of them assigned to a particular line of investigation. The predominant
management style at the Palace is best described as a wheel, with the lab chief at the hub and the staff all
extending outward as individual spokes, each totally ignorant of what the
others are up to. This ensures an atmosphere
that is very secretive, which lab chiefs can then exploit in their
efforts to
motivate
the postdoes. Two or three people may be assigned to the same experiment,
sometimes even doing the exact same work. The chief can then use them against
one another to ensure accuracy “Paul did such and such,” he’ll say to Peter. “But I don’t really believe it. You think Paul’s
off base, don’t you?
Why
don’t von repeat the experiment and find out what’s really going on.” Managed
competition we call it—a technique that Sol used in his lab at Hopkins, and one
that a large number of other successful scientists of his generation have used. As a management style, it can be extremely productive, but not a lot of
fun, especially if you’re one of the spokes in the wheel.
In my own lab, I consciously tried to develop
a nurturing, even maternal
mode of management, motivating people by praise rather than criticism, by team
spirit rather than competition with each other. The rejection I had experienced after the Lasker episode sensitized me to
the pitfalls of the gamesmanship in lab politics, making me want to have as
little to do with it as possible. I strived to create an atmosphere in my lab
that would allow for more collaboration, opening up doors for different labs to
work together on joint projects instead of viciously competing with one another
to win funding and glory.
Much of the work
we did in my NIMH lab, both before and after the Lasker incident, was a
continuation of the brain-receptor mapping I’d been doing since my days in
Sol’s lab. We went on the assumption that any peptide that could be found
anywhere in the body would have a specific receptor for a perfect fit somewhere
in the brain—hence the term neuropeptide.
We proved this by putting one peptide
after another through assays constructed along the lines of the original opiate-receptor experiment
and detecting if there was binding.
Someone
dubbed this process “grind and bind.” grind
for the process of pulverizing the tissue into milkshake consistency, and bind for the action of the peptide as it
docked onto its receptor.
Our
grind-and-bind assay method was soon replaced by a new autoradiographic technique, which further confirmed
the distribution of receptors for all the known peptides at
different locations in the brain. In developing this, I worked closely with
Miles Herkenham and Remi Quirion to take the art of receptor autoradiography to
the next level of precision, creating a quick and easy way to visualize the
receptors in the brain, and even see their levels of density.
My first contact
with Miles was on the phone, when, shortly after arriving at the Palace in
1977, he called to invite me to a talk he was giving. Miles was a
neuroanatomist who had studied with the renowned
Walle Nauta at MIT, the
scientist who had earned my admiration for interpreting our opiate-receptor
assay data and locating the densest concentrations in the limbic, or emotional,
brain. Miles, like Nauta, was involved in constructing a circuit diagram of the
neuronal cells and their pathways,
an ongoing project
scientists had been working at for almost a century in
the hope that it would reveal the full extent of the electrical brain. However,
their methods had not yet enabled them to determine
which neurotransmitters were secreted by a particular neuron.
Antoradiography
had allowed Miles to map the pathways of neurons and axons, which showed up as
round holes on his film, making for a kind of Swiss-cheese effect, as if myriads of tiny islands were afloat in a sea of microseopically viewed tissue.
The work Mike
Kuhar and I had done when I was a graduate student at Hopkins had yielded a map
of the chemical brain on which the receptors, when visualized looked
like tiny dark patches against a lighter tissue
background.
Having
read about that project, Miles had been wanting to ask me for some time: Could
his holes match my patches? Would his electrical brain mapping correspond to my
chemical brain mapping?
When I attended
his talk. I was stunned by the slides Miles showed, so beautiful, the tiny
neurons showing up like the Milky Way projected against a vast black universe. Barely did I encounter a scientist who had an aesthetic
sense, most of them preferring a drier, numbers-only approach, But Miles had an
unusual respect for the natural beautv of what he was seeing, and I resolved
then and there to work with him. And he himself
was as gorgeous as his slides—a
real hunk!
Our
collaboration resulted in a great improvement on the tedious visualization
methods I’d used back at Hopkins, and greatly advanced the art of receptor
autoradiography, moving it from binding in animals in vitro to binding on
slides of
presliced brain (in vitro). “Slip and dip,” as we called the new methodology
involved fixing radioactively labeled liquids to receptors and dipping them in
a radiosensitive liquid emulsion. While it was a difficult and unforgiving
method, partly because much of it had to be done in the dark, it produced excellent results, allowing us to see
receptors as tiny sparkling grains in a sea of colorfully stained brain tissue.
A much simpler and quicker method
that we developed, which was eventually
adopted as the state-of-the-art technique, involved taking the brain slice alter it had
been fixed on the slide, after the receptor is hound in vitro, and putting; it up against radiosensitive film, which is housed in a cassette.
In theory,
it was a great idea, but our first attempt was a total bust, yielding
black on black.
We were about to abandon the pursuit when chance brought
me to a conference where I met up with my old friend from graduate
school days, Anne Young. Now the head of neurology at Massachussetts General
Hospital. Anne is renowed for her unpretentions, zesty humor. She graduated
first in her class at Vassar, wearing a molecular model “hat” on her head,
which she gaily tipped to the president
on receiving her diploma. One night during the conference, we went to Anne’s room and talked well into the night, catching
up and enjoying the bottle of Scotch I’d brought with me, and Anne happened to
mention that her lab had been working with the slip-and-dip method Miles and I
had developed, and had refined it. I
was all ears.
“We
put the slide up against the film, in a cassette,” she volunteered. “Really.” I
said. “Miles and I had the
same idea, but we couldn’t get it to
work.”
“But it’s so
easy. You’ve already done the hard part, labeling the receptor in the tissue
and then getting it to stick on the slide,” she said matter-of-factly. “I bet you put the film in backwards—an easy mistake to make in the pitch dark.”
In a stunning example
of how scientific schmoozing can create a breakthrough, leading to the correction
of the one “tiny” mistake in a long chain of
well-executed experimental steps, Anne had given us the key. Back in Bethesda the next day,
I went to work with pharmaceuticals expert Sandy Moon, an African-American
woman who was one of the elegant, brilliant scientists I’d been able to attract
to my lab. She put the same slides up against the correct side of the film for me, and instant Eureka! A
more valuable bottle of Scotch I don’t think I’ve ever shared with a friend.
This new
technique allowed us to map our receptors in a week, rather than spending up to
a year on each receptor. Now we could find receptors easily and quickly for ourselves, as well as for the many labs
engaged in this kind of research
and needing to identify a particular peptide. My postdoc Remi Quirion was
immediately put on a project to find the PCP (“angel dust”) receptor, and he
found it right away. A Canadian whose parents ran a diner, Remi was a brilliant
short-order cook in the lab who turned autoradiographv into a process that
resembled a fastfood operation. By the time he was ready to leave my lab, Remi
was using his autoradiography technique to collaborate with several other labs
in the Palace.
While the new
method was incredibly efficient at locating the receptors, it also allowed
us to expand aesthetically and bring color to autoradiography. Up
until
then, the different densities had appeared in black and white only, making it
difficult to discern subtle fluctuations. Now, because the image was on film,
we could employ the computer to use color coding, giving us quantitative
receptor autoradiographv. This made the density of the receptors in the brain
visible by giving us a picture that resembled a modern-day weather map showing temperature gradients for different
geographical areas. Areas that showed up as yellow might indicate a certain number
of receptors, while
areas that were orange or purple might indicate
greater or lesser numbers. We came to call our cassette and computer
combinations “the rainbow machine,” evoking for me my favorite symbol
of the promise of science.
When I looked at the images. I thought they resembled colorful
butterflies, and I couldn’t resist making some of them into posters to grace
the otherwise sterile hallway walls. I fantasized that we’d invented a new art
form called “photoneurorealism” that would be shown one day in a New York gallery—exquisitely beautiful and full of scientific data.
Now we went to work on our goal of connecting the neurochemical maps of the peptides
and their receptors with the circuit diagrams that the anatomists had been
working on for years. Miles’s circuit diagrams showed the actual wiring of the
brain, its electrical reality, and marked out paths of communication between the nerves, axons, and dendrites. By
overlapping our autoradiographic maps with his diagrams, we could see which
nerve pathways had receptors for endorphins and which could receive
messages carried by other peptides. At the time it was my dream that we’d soon have a large
color-coded map of the brain showing the chemical system as it interacted with
the electrical, a veritable rainbow of color
and information.
Another finding
that emerged from our color autoradiography was just how rich the emotional or
limbic, areas of the brain were in the receptors for peptides that regulated
the pleasure/pain continuum. Miles had already mapped some of these limbic
connections anatomically in particular the thalamus-to-cortex pathways of
neurons in the brain. Now we could see how the opiate receptors were following the exact same pathways as
the subgroup of thalamic neurons connected to the limbic system. We jokingly
called our newly revealed spots “love patches,”
because the fit precisely over Miles’s floating
island holes. At last we had confirmed that the holes
on his film, which were formed by neurons projecting to the limbic system, were a match for my opiate-receptor patches, and in August 1983 we had a
gorgeous, full-color cover of Nature magazine
to illustrate our findings.
In my more leisurely
moments, when I could take time away from the
minutiae,
the day-to-day routine, I dreamed of a grand mosaic design, one made up of all the
neuropeptides and other messenger molecules being discovered by my lab and others.
Surely what we were seeing was the basis for some kind of complex communication
within the brain. And since the brain peptides and their receptors were showing
up throughout the far-flung systems of the body, perhaps this was an indication
that communication was taking place not just within the brain, but between
the brain and the rest of the body. I was beginning to wonder: Did all
these systems hook up somehow? And if so, why?
PROCESS
By the early eighties,
although the Palace air was still charged with
competition, our lab had become a hotbed of collaboration and exchange. In 1982 I was promoted to section chief in
brain biochemistry, and with a staff sometimes numbering as main as fifteen, I
was in heaven. Scientists from within and without the Palace walls were calling
my lab every day for appointments to have their peptide and receptor findings
autoradiographed for possible measurement and location
in the brain. A researcher might drop by to show me
the data for an experiment using naloxone to control the eating behavior of his
overweight rats. He had found that when the opiate receptors were blocked, the rats ate less, suggesting that endorphins
might be somehow invoked in obesity. Could I measure the output of endorphins
in the rats’ pituitary glands? Another researcher might call to tell me of her
study that correlated mood swings to the menstrual cycle. Could the emotional
upswing occurring between days five and seven
be explained by endorphin release?
A psychiatrist might come by to
discuss the work he was doing with patients
extremely sensitive to pain and
unable to get relief from even the strongest painkilling drugs. Could I measure
the endorphin levels in these patients blood? The stream was endless, and I
loved every moment of it.
Things were
moving so fast during that time period that I often felt like a juggler adeptly
spinning plates on the top of two long poles held in each hand. Getting the
plates to spin was only half the job. Keeping them in motion—that’s the art. If
one plate falls to the ground, if an experiment crashes and must be shut down, even for a few weeks,
the task of getting it up and spinning again
might be impossible. The technology seems to have a life of its own—once
it ceases to work, it’s dead,
and it can take months,
sometimes years, to bring it back to life
again.
The assay to
measure endorphins in the blood, the assay to locate receptors in the brain,
and autoradiography—these were the plates I attempted to keep spinning. Every day in my lab my postdocs
would use these techniques, training their successors to do the same when they
moved on. We might ask different questions, but the technology remained the
same. For example, we wanted to understand how the opiate receptor and
endorphin system had evolved over time, and to map this progress
using autoradiography. To do this, we would examine
the fetal rat brain at three days in utero, then seven days, then fifteen days, patiently recording the changes in cells
and structures. Then we used the same technique to see how these systems
had developed in the brains of monkeys.
We’d
ask: Were the receptors densest in those locations where sensory input was
received from the ears, eyes, nose, mouth, and skin? Were they thickest in the
cerebellum or in the neocortex?
My method was to develop a technique and then ask all the questions to which the technique could supply an
answer. This process can go on for years as you keep gathering pieces of a
puzzle that gradually add up to a big picture of which you catch only fleeting glimpses
along the way. And then one day when
the light flashes on in your brain, you see the big picture, the grand scheme,
and it all comes together: all the data you’ve been accumulating for
years starts to make sense. Or maybe
you never get to that point and, instead, continue to create new techniques, brainstorm more questions, create more data,
massaging it all into shape for publication. Then
maybe someday someone else will see it, and it will be the missing
piece of a puzzle he or she has been working on for years.
Most people
think of science as a series of dramatic results, breakthroughs, advances, but
science is really first and foremost a process. You start out on one path and
then take a sudden turn to find yourself going down a totally different road.
Sometimes the steps are small and the progress incremental. In my lab, when nothing was
working, my postdocs would become downcast and dejected. There were some
extremelv dry spells when only one out of ten projects was producing results,
and that single success was usually a dull, bread-and-butter experiment that
didn’t excite anyone’s imagination. But at the Palace, these were often the
kinds of projects that satisfied your superiors and ended up fattening your publication score. A smart scientist
tried to balance a few chancy personal long shots with a larger number of
tried-and-true experiments, ones that would never product any fireworks, but
were solid guarantees.
One of my personal long shots was a project I designed to find the marijuana
receptor.
This was one I wanted to bag myself, to prove we had in our brains a natural
marijuana that we could potentially access to
create a natural high without
smoking pot. I labored over this one For two years, trying hundreds of clever
little things, all of which consumed an abysmal amount of my time and
ultimately failed to produce results because I never managed to get hold of the
right ligand. Without that ligand,
all my efforts, hundreds upon hundreds of hours
of hard labor,
had less than a snowball’s chance in hell of ever bringing
me the marijuana receptor. So, eventually, I bowed to the inevitable and turned
my attention to other things. Fortunately, there were lots of other ongoing projects to occupy me, far too many to
explain, and lots of successes among them.
In the end, and only recently, it was my friend Miles Herkenham, who, having
procured the right ligand, was able to successfully visualize the cannabis
receptors in rat brains.
I barely
glimpsed it then, but the work we were doing in my lab during this time was
laving the groundwork for a huge discovery, one that would lead us to formulate
a radical theory that explained the link between mind and body, and how the
emotions are directly involved with health and disease. My father’s diagnosis
of lung cancer in 1980, and the research I subsequently did in a desperate
attempt to save his life, helped me begin to see this connection. But it wasn’t
until I was drawn into yet another, new level of personal involvement with my science that I was able to take a
giant step out of the old paradigm and boldly follow what, deep in my heart, I
knew to be the truth.
7 THE BIOCHEMICALS OF EMOTION: A CONTINUED LECTURE
I’M FEELING confident that my listeners have
been properly introduced to the basic biochemicals of emotion, the
neuropeptides and various other ligands and their receptors, and have learned a bit about how we scientists came to
understand them. They have also learned a little about both the electrical and
the chemical aspects of the brain, and how the neurotransmitters making their
electrically fired leaps across brain synapses are just one part of a much more
far-flung network of information carried by neuropeptides and their bodywide
receptors. We are now ready
to explore my theory that these biochemicals are the physiological substrates of emotion, the molecular
underpinnings of what we experience as feelings, sensations, thoughts, drives,
perhaps even spirit or soul. As a result
of the work done in my own lab, as well as many others,
and presented in a number of theoretical papers and lectures, there is
now much evidence to support this theory.
And so, with the
house lights still dim, I gaze directly into the pool of eager eyes, minds, and
hearts before me and begin explaining the most radical implications of my
work—implications I could barely begin to articulate at the time I was first
describing the research in the professional journals. What I will describe to you today—why you feel the way you feel—is my latest thinking
on a subject that has consumed me for over a decade. My ideas grew from
a synthesis of
many diverse sources, ranging from my own work in the laboratory, to research done by today’s leading theorists
of emotion, to the latest findings of a global community of neuroscientists.
My personal exposure to a number of mind-body therapies emphasizing the
importance of the emotions—particularly the
power of their full expression to release us from the joy-and health-sapping
patterns of the past—has gradually increased my confidence in the validity of these ideas.
WHAT DO I MEAN BY EMOTIONS?
I should say first that some scientists
might describe the idea of a biochemical
basis
for the emotions as outrageous. It is not, in other words, part of the
established wisdom even now. Indeed, coming from a tradition where experimental psychology textbooks (which
focus on the observable and measurable) do not even contain the word emotions in the index, it was not without a little trepidation that I dared
to start talking about their biochemistry! I grew bolder in 1984 when Paul
Ekman, a highly respected psychologist who studies human emotion at the
University of California at San Francisco, introduced me to Charles Darwin’s book on the
subject. If the great Darwin himself had thought it important, then surely I was on firm ground.
In Expression of the Emotions in
Man and Animals, Darwin explained how people everywhere have common
emotional facial expressions, some of which are also shared by animals. For example,
a wolf baring its fangs uses the same facial musculature as any human
being does when angry or threatened. The same
simple physiology of emotions has been preserved
and used again and again over evolutionary eons and across
species. On the basis of the universality of this phenomenon, Darwin speculated
that the emotions must be key to the survival of the fittest.
To quote The Selfish Gene, by Richard Dawkins, on
the subject of the relationship between evolution and survival mechanisms: “A
duck is a robot vehicle for the propagation of duck genes.” This is but another
way of making Darwin’s point that if emotions are that widespread across both
human and animal kingdoms, they have been proved, evolutionarily, as crucial to
the process of survival, and are inextricably linked to the origins of the species.
When I use the
term emotion, I am speaking in the
broadest of terms, to include not
only the familiar human experiences of anger, fear, and sadness, as well as
joy, contentment, and courage, but also basic sensations such as pleasure and
pain, as well as the “drive states” studied by the experimental psychologists,
such as hunger and thirst.
In addition to measurable and observable emotions and states, I also refer to an assortment of other intangible, subjective experiences that are probably unique to humans, such
as spiritual inspiration,
awe, bliss, and other states
of consciousness that we all have experienced but that have been, up until now, physiologically unexplained.
I must tell you that the experts—the
emotional theorists who have their own scientific data to interpret—disagree
about many things, including whether feelings are the same as emotions, how
many basic or core emotions there really are, or even whether these are useful
questions at all! They do agree, however, that
there is now clear scientific experimental evidence that the facial
expressions for anger, fear,
sadness, enjoyment, and disgust are identical
whether an Eskimo or an Italian is being studied. Facial expressions that register
other emotions such as surprise, contempt, shame/guilt are probably also
pancultural, meaning that these, too, are emotions with inborn genetic mechanisms for their expression. And there
probably are more genetically based emotions to discover.
Robert Plutchik,
a psychology professor
at Hofstra University whose emotions research influenced me as an undergraduate,
proposed a theory of eight primary emotions—sadness, disgust,
anger, anticipation, joy, acceptance, fear, and surprise—which, much like primary
colors, could be mixed to get other, secondary emotions. For example, fear +
surprise = alarm, joy + fear = guilt, etc.
Whether or not Plutchik’s classification is borne out by more research, the idea
of certain emotions being mixed to produce other emotions is interesting, and
suggests that when other factors such as intensity and duration of emotion are
considered, there may easily he hundreds of subtle emotional states.
The experts also
distinguish among emotion, mood, and temperament, with emotion being the most
transient and clearly identifiable in terms of what causes it; with mood
lasting for hours or days and being less easily traced; and with temperament
being genetically based, so that we’re generally stuck with it (give or take certain modifications) for a
lifetime. For example, Harvard psychology professor Jerome Kagan has proved
that readily measurable traits like the tendency
to be startled by novel stimuli can be shown most readily in those infants who go on to develop into shy
children and adults.
THE LIMBIC SYSTEM OF THE BRAIN: CLASSICAL SEAT OF THE EMOTIONS
For a long time,
neuroscientists have agreed that emotions are controlled by certain parts of
the brain. This is a big, “neurocentric” assumption—and I now think it is a
wrong (or at least incomplete) one! Still, as a neuroscientist and a onetime
believer in the brain as the most important organ in the
body, I was led by this assumption
to do the right analysis for the wrong reason. During the mid- 1980s, with my NIH lab colleagues Joanna Hill and Birgit Zipser,
I systematically analyzed the brain distribution patterns of twenty-two
different neuropeptide receptors that our lab had mapped
over the years,
comparing them to the
classical emotional brain areas of the limbic system—a hypothetical
construct, known
as the seat of the emotions, which
has come to include more and more brain structures over the
years. We confirmed for many other neuropeptide receptors what we’d first seen
for the brain distribution of opiate receptors, the very first neuropeptide
receptors to be mapped: Core limbic brain structures, such as the amygdala,
hippocampus, and limbic cortex, believed by neuroscientists to be involved in
emotional behavior contained a whopping 85 to 95 percent of the various
neuropeptide receptors we had studied! This concordance fueled
my conviction (which
had first begun
to develop as I
mapped opiate receptors in the late 1970s and early 1980s) that there was such
a thing as the molecules of emotion.
Human experiments showing the connection between emotions and those
parts of the brain where we were now locating almost all the neuropeptide
receptors had been done at McGill University in Montreal by Wilder Penfield in
the 1920s. Working with conscious, awake individuals during open-brain
surgery to stop severe and uncontrollable epilepsy, he found that when he
electrically stimulated the limbic cortex over the amygdala (the two almond-
shaped structures on either side of the forebrain, about an inch or so into
your brain from your earlobes), he
could elicit a whole gamut of emotional displays— powerful reactions of grief,
anger, or joy as patients relived old memories, complete with the appropriate
bodily accompaniments such as shaking with rage or laughter, weeping, and blood pressure and temperature
changes.
Another
indication that neuropeptides and their receptors might be plausible candidates
for the locus of the emotions was that they met Darwin’s criterion: The
physiological basis for the emotions, he predicted, would be found “conserved”
throughout evolution. Given their important role in the survival of the
species, they would appear again and again throughout the various evolutionary
stages of the animal kingdom. In fact, the receptor-mapping experiments I’d
done with radioactive opiates like morphine and naloxone had shown that
identical opiate receptors could be found in the brains of all vertebrates, from the simple,
hideous hagfish to the complex,
exalted human.
Even
insects and other invertebrates could be shown to have opiate receptors. Darwin
himself could write only about the physiology of emotions and not about their
biochemistry or genetics because the concept of biochemistry, with its specific
components, the proteins and peptides (direct products of genes), would not be
discovered for almost a hundred years. But I think he would see in such work
the confirmation of his brilliant hunch.
IT WAS NIMH researcher
Paul MacLean who popularized the concept of the
limbic
system as the seat of the emotions. The limbic system was one constituent of
his triune brain theory, which held that there are three layers to the human brain, representing different stages of
humanity’s evolution—the brainstem (hindbrain), or reptilian brain, which is responsible for breathing, excretion, blood flow, body temperature,
and other autonomic functions; the limbic system, which encircles the top of
the brainstem and is the seat of the emotions: and the cerebral cortex, in the
forebrain, which is the seat of reason.
Back in 1974, I
had an opportunity to visit with the prominent physician- scientist when I went
to his NIMH laboratory to deliver a lecture about my then new opiate-receptor
discovery. Afterward, Paul mischievously led me past cages of monkeys who shrieked and shook their
genitals at me in an intense display evolved to frighten intruders off their
turf. Even back then Paul was fielding questions about just how much the
limbic-system concept was accurate science and
how much was metaphor. But what really excited me that day was the discussion we had about
the fact that opiate receptors are by far the densest
in the frontal lobes of the cerebral cortex of the human brain, which
share many interconnections with the amygdala, one of the so-called limbic
structures. As Paul
emphatically tapped his forehead in front of his frontal cortex—the most newly
evolved of the brain structures, and the one that is most fully developed in
human beings—I thought about the physiological and biochemical pathways that
had had to be forged between that cortex and the rest of the brain to enable humans to learn to control their emotions
and act unselfishly. Although the capacity for learning is to some extent
present in even the simplest creatures, willpower is the uniquely
human “ghost in the machine,”
and Paul was sure that it resided only in the frontal
cortex.
DO EMOTIONS ORIGINATE IN THE HEAD OR THE BODY?
Until 1984 I had
assumed that Wilder Penfield’s famous human experiments had proved beyond a
shadow of a doubt that emotions originate in the brain. But that year, I went
to give a lecture at the Second International Meeting of the Society for the
Study of Emotion, which was held at Harvard, and there I met Eugene Taylor, the
scientific historian in the psychology department. He was excited about the
lecture I had just delivered, in which I presented the theory of peptides and other ligands
as the biochemicals of emotion.
Gene wanted to know
where
I stood on the famous James-Cannon debate, which, he reminded me, was about the
ultimate source of emotions. Do they originate in the body and then get
perceived in the head, where we invent a story to explain
them, as William James said? Or do they originate
in the head and trickle down to the body, as Walter Cannon posited?
In 1884,
while an assistant professor of philosophy at Harvard, William James had published his essay
“What Is an Emotion?” basing his theory on his own introspective observations
and a general knowledge of physiology. He said he had concluded that the source
of emotions is purely visceral, that is, originating
in the body and not cognitive, originating in the mind, and that there is probably no brain center for emotional
expression. We perceive events and have bodily feelings, and then after the
perception, which joggles our memories and imagination, we label our physical sensations as one or another emotion.
However,
he believed that there was in fact no such entity as emotion. There is simply
perception and bodily response. The immediate sensory and motor reverberations
that occur in response to the perception—the pounding heart, the tight stomach,
the tensed muscles, the sweaty palms—are the
emotions. And the emotions are felt throughout the body as sensations, “each
morsel of which contributes its pulsations of feeling, dim or sharp, pleasant
or painful or dubious, to that sense
of personality that every one of us unfailingly carries with him.” Emotions
consist of organic changes in the body, muscular and visceral, and are not a
primary feeling directly aroused, but a secondary one, indirectly aroused by
the body’s workings.
Like many
appealing armchair theories, James’s seemed to collapse under the weight of real data, in this case, animal laboratory work performed by his
student Walter Cannon, the experimental physiologist and author of Wisdom of the Body, who, by 1927, had explained the
workings of the sympathetic autonomic
nervous system. A single nerve called the vagus (“wandering”) nerve exits the
back of the brain through a hole in the bottom of the skull (the foramen
magnum), then splits to run down the bundles of nerve cells, or ganglia, along
either side of the spinal cord to send branches to many organs, including the pupils of the eye, the salivary glands,
the heart, the bronchi of the lungs, the stomach, the intestines, the bladder,
the sex organs, and the adrenal glands (from which the hormone adrenaline is
released). When Cannon stimulated the vagus through electrodes implanted in the
hypothalamus in the bottom of the brain just above the pituitary gland, he
demonstrated physiological changes in all these organs consistent with what would be needed by the body in an emergency
situation
when resources had to be quickly, efficiently, and automatically managed
without any time-wasting thought. As the result of this hypothalamic
stimulation, for example, blood from the internal organs of digestion was quickly rerouted to the muscles for “fight
or flight”—digestion could wait until the emergency was over—and an increased
output of adrenaline stimulated the heart and
caused the liver to release extra supplies of sugar for
instant energy.
From Cannon’s
point of view, James’s theory of visceral
emotion was all wet.
Cannon could accurately measure how much time it took from the moment the
hypothalamus got an electrical jolt to the moment the bodily changes in blood
flow, digestion, and heartbeat began to occur as a result. And his conclusion
was that these changes were just too slow to be the cause of emotions rather
than the effect. Also, artificial induction of visceral changes that were
typical of strong emotions, such as the use of electrical current to produce a
strong intestinal contraction like that which occurs in the first moment of
panic, failed to produce the other signs of that emotion. Not only that, Cannon
pointed out that animals whose vagal nerve had been cut, and presumably were
incapable of sympathetic visceral bodily changes,
still seemed to behave just as emotionally when placed in a
threatening situation. According to Cannon, the hypothalamus of the brain was the seat of the emotions, which
trickled down to the body through the hypothalamus’s neuronal connections to
the back of the brain, or brainstem, or through the secretions of the pituitary
gland.
While Eugene Taylor waited expectantly for my late-twentieth-century spin on the somewhat arcane James-Cannon
debate, I suddenly had a big aha!: “Why, its both! Its not either/or; in fact,
its both and neither! It’s simultaneous—a
two- way street,” I blurted out. I had just realized
that the resolution of a debate whose origins went hack over a
century held the key to understanding a very modern conundrum: How can emotions
transform the body, either creating disease or healing it, maintaining health or
undermining it?
This also helped
me to understand the reading I’d recently been doing on biofeedback, which is
the technique of using monitoring devices to measure various bodily functions
(for example, heart rate or blood flow) as a step toward gaining control
of those functions. Biofeedback can enable ordinary folks (and
not just ascended yogis) to attain a state of deep relaxation in which it is
possible for them to take conscious control of physiological processes
previously thought to be autonomic
and not susceptible to voluntary intervention. For example, anyone can increase
the temperature of his hand by 5 to 10 degrees, often on the very first try. Elmer Green, the Mayo Clinic physician who had pioneered
in
biofeedback
for treatment of disease, had said, “Every change in the physiological state is
accompanied by an appropriate change in the mental emotional state, conscious
or unconscious, and conversely, every change in the mental emotional state,
conscious or unconscious, is accompanied by an appropriate change in the
physiological state.” Taylor’s question had led me to another insight into the
meaning of the discoveries we’d been making about the location of peptides and
their receptors, and about the theories we’d been formulating about these
molecules of emotion.
BEYOND SYNAPSES: A NEW MODEL OF INFORMATION EXCHANGE
In the 1960s, the
emerging science of neuropharmacology focused on neurotransmitters being released from nerve endings,
traveling across synapses to ignite another electrical
discharge, in a hardwired (neuron-to-neuron), point- to-point hookup of traveling neuronal impulses. All brain
functions, even for the most complex levels of mental activity and behavior,
were thought to be determined by the synaptic connections between billions of
neurons. The synapses formed the
networks and defined the neural circuits whose chatter was thought to dictate every aspect of perception, integration, and performance. At the synapse, the models for both the
electrical and chemical brain seemed to merge. There were no discrepancies,
just exciting concordances, as neurochemistry, the new field of mapping
neurotransmitters, seemed to confirm the existence of the neuroanatomical brain
circuits discovered previously, and to reveal new ones as well.
For example,
Arvid Carlson and the Swedes (as we American neuroscientists collectively refer
to the school of crackerjack neurohistochemists working in Stockholm) had
invented a method for visualizing nerve endings in the brain that contained norepinephrine, also called noradrenaline. Using this new tool, they saw that a tiny cluster of previously
unremarkable cell bodies in the hindbrain, called the locus coeruleus,
projected its norepinephrine-containing nerve endings into the forebrain, and that all the norepinephrine in the forebrain
comes from this one source.
Then psychologist Larry Stein at Wyeth Labs and Bryn Mawr College showed that
what previous research had called the “pleasure center” or “pleasure pathway”—an area of the brain that when electrically stimulated caused rats (and humans) to ignore the need for food and sleep in a frenzy
of
pleasure
and excitement—contained within it this locus coeruleus. Unbeknownst to those earlier researchers, the
electrical stimulus had worked by causing the release of norepinephrine from
the nerve endings along the pathway.
Amphetamines
and cocaine were shown to work by amplifying this same “pleasure pathway,” blocking re-uptake of the neurotransmitter
norepinephrine and thus increasing
the amount of it that came in contact with its receptors, all of which were
believed to be located just across the synapse.
And so matters
stood for a couple of decades, with neurochemists amplifying and elaborating on
work that had been done in earlier decades by the neuroanatomists. But that
work didn’t go far enough.
Enter a new
theory of information exchange outside the bounds of the hardwired nervous
system, focused on a purely chemical, nonsynaptic communication between cells.
My lab at the NIMH, having specialized in the neuropeptides, had not only mapped their receptor sites throughout the brain,
but, by the early 1980s, with the help of my post-doctoral fellow Stafford
Maclean, had also devised a new autoradiographic method for identifying where
the neuropeptides are produced, a technique that enabled us to take a much
broader perspective. Suddenly, we felt like we were flying above a forest
rather than studying the bark on the trees.
While Miles
Herkenham and I had previously confirmed the lovely concordance that we had
hoped to find between certain electrical pathways and the chemical
patterns of opiate
receptors, the new method revealed
a discrepancy. Studying the ton of new data on numerous neuropeptides
and their receptors, data that had been produced in his lab, our own, and many
others by the early 1980s, Miles was
struck by a disturbing “mismatch” between what we thought we knew and what we
were seeing. Something was wrong. If peptides
and their receptors were communicating across
the synapse from each other, they should be only minuscule
distances apart, but their location was not conforming to this expectation. Many
of the receptors were located in far-flung areas, inches away from the
neuropeptides. So we had to wonder how they were communicating, if not across
the synaptic gap. Miles concluded that the largest portion of information
ricocheting around the brain is kept in order not by the synaptic connections
of brain cells but by the specificity of the receptors—in other words, by the ability of the
receptor to bind with only one kind of ligand. Miles has estimated that,
counter to the collective wisdom of the neuropharmacologists and
neuroscientists, less than 2 percent of neuronal communication actually occurs
at the synapse. It was so radical an idea that for several years his
observation of the mismatches was
ignored and attributed to
artifacts
of the mapping techniques. In fact, the way in which peptides circulate through
the body, finding their target receptors in regions far more distant than had
ever previously been thought possible, made the brain communication system resemble the endocrine system, whose
hormones can travel the length and
breadth of our bodies. The brain is like a bag of hormones! Our view of the
brain, and the metaphors we used to describe it, were permanently altered.
In 1984,
at around the same time that
Miles was teaching me the significance of the mismatch in the mapping studies,
Francis Schmitt, an elder statesman of neuroscience from MIT who had originated
the Neuroscience Research Program, introduced the terminology of “information
substances” to describe a variety of transmitters, peptides, hormones, factors,
and protein ligands. Alongside the conventional model of synaptic neuronal
circuitry, Schmitt proposed a parasynaptic, or secondary, parallel system,
where chemical information substances
travel the extracellular fluids circulating throughout the body to reach their specific
target-cell receptors. His idea was readily accepted,
as was his vivid terminology.
THE MIND-BODY CONNECTION: EMOTION- CARRYING PEPTIDES
Suddenly, the
number of possible lines of communication between the brain and the body seemed to explode for me. There
were numerous alter
natives to the synaptic nerve
hookups that once seemed indispensable for mind-body communication, and we were
beginning to learn what was getting communicated through those connections. For
example, the receptors for sex hormones that had been unexpectedly identified
in the brain and then ignored for many years were clearly the mechanism through
which testosterone or estrogen, it released into the
fetus during pregnancy, could determine neuronal
connections in the brain
and permanently affect the sexual identity of the child. John Money, the famous
Johns Hopkins psychiatrist, had shown that female fetuses exposed to testosterone-like steroid hormones
(aberrantly produced by their pregnant mothers’ adrenal
glands) were more likely to become tomboys
and avoid dolls!
Also, numerous
additional nerve hookups could now be discovered thanks to the invention of new
biochemical tools with which to examine them. Scientists began to follow up on
the pioneering mid-1980s work of Tomaas Hokfeldt (one of the Swedes),
who had reported that the classical autonomic
nervous system
described
in Cannon’s work unexpectedly contained just about every neuropeptide that he had sought there. Neuropeptides could be
found not only in the rows of nerve ganglia on either side of the spine, but in
the end organs themselves. An era of discovery began that is still in full swing,
as neuroscientists began tracing the precise connections among all the
parts of the body. New peptide-containing groups of neuronal cell bodies in the
brain called “nuclei,” the sources of most brain-to-body and body-to-brain
hookups, are now being elaborated upon every day.
To cite just one
recent example, Rita Valentino of the University of Pennsylvania has shown that the nucleus
of Barrington in the hindbrain, formerly believed to control
merely micturition (bladder-emptying), sends axons containing the neuropeptide CRF down through
the vagus nerve all the way to the most distant part of the large
intestine, near the anus. Rita has proved that sensations of colonic distention
(i.e., the feeling of needing to poop) as well as those of genital arousal
are carried back to the nucleus of Barrington. From there, there is a short neuronal
pathway (called a“projection”) that hooks up to
the locus coeruleus, the norepinephrine-containing source of the“pleasure
pathway,” which is also very high in opiate receptors. The pleasure pathway hooks up to the control area of these
bathroom functions, which is located in the front of the brain.
Goodness, is it any wonder,
based upon Rita’s neuroanatomical discoveries, that toilet training is loaded
with emotional stuff!
Or
that people get into some unusual sexual practices involving bathroom
behaviors! Clearly, the classical physiologists had grossly underestimated the
complexity and scope of the neurochemistryand neuroanatomy of the autonomic
nervous system. But the limitations of the past are now giving way before our
newfound ability to track these fascinating connections.
If we accept the
idea that peptides and other informational substances are the biochemicals of
emotion, their distribution in the body’s nerves has all kinds of significance,
which Sigmund Freud, were he alive today, would gleefully point out as the
molecular confirmation of his theories. The body is the unconscious mind!
Repressed traumas caused by overwhelming emotion can be stored in a body part,
thereafter affecting our ability to feel that part or even move it. The new
work suggests there are almost infinite pathways for the conscious mind to
access—and modify—the unconscious mind and the body, and also provides an
explanation for a number of phenomena that the emotional theorists have been considering.
THE MIND IN
THE BODY: FILTERING, STORING, LEARNING, REMEMBERING, REPRESSING
Because of the
research I’ve been describing, we can no longer consider the emotional brain to
be confined to the classical locations of the amygdala, hippocampus, and
hypothalamus. For example, we have discovered other anatomical locations where
high concentrations of almost every neuropeptide receptor exist, locations such
as the dorsal horn, or back side of the spinal cord, which is the first synapse
within the nervous system where all somatosensory
information is processed. (The term somatosensory refers to any bodily
sensations or feelings, whether it is the touch of another’s hand on our skin
or sensations arising from the movement of our own organs as they carry on our
bodily processes.) Not just opiate receptors but almost every peptide receptor
we looked for could be found in this spinal-cord site that filters all incoming
bodily sensations. In fact,
we have found that in virtually all locations where information from any of the five
senses—sight, sound, taste, smell, and touch— enters the nervous system, we
will find a high concentration of neuropeptide receptors. We have termed these
regions “nodal points” (or, colloquially, “hot spots”) to emphasize that they
are places where a great deal of information converges. The information is
carried by axons and dendrites from many nerve
cell bodies that are passing near
or making synaptic contact with each other.
These nodal
points seem to be designed so that they can be accessed and modulated by almost
all neuropeptides as they go about their job of processing information,
prioritizing it, and biasing it to cause unique neurophysiological changes. For
example, the nucleus of Barrington is one such nodal point, since it contains
many neuropeptide receptors, and depending on what neuropeptide is occupying
its receptors, feelings related to sexual arousal or bathroom functions can be
switched or modified, made unconscious, or moved to the most urgent priority.
Emotions and bodily sensations are thus intricately intertwined, in a
bidirectional network in which each can alter
the other. Usually
this process takes place at
an unconscious level, but it can also surface into consciousness under certain conditions, or be brought into consciousness
by intention.
All sensory
information undergoes a filtering process as it travels across one or more synapses, eventually (but not
always) reaching the areas of higher processes, like the frontal
lobes. There the sensory input—concerning the view,
the
odor, the caress—enters our conscious awareness. The efficiency of the
filtering process, winch chooses what stimuli we pay attention to at any given
moment, is determined by the quantity and quality of the receptors at these
nodal points. The relative quantities and qualities of these receptors are
determined by many things, among them your experiences yesterday and as a
child, even by what
you ate for lunch today.
Think of the brain as a machine for not merely
filtering and storing
this sensory input, but for associating it with other events or stimuli
occurring simultaneously at any synapse or receptor along the way—that is,
learning. Let’s look at how this occurs in the process of vision, which is very
advanced complex in humans. After
a visual signal hits the retina, the
light-sensitive part of the eye, it
must make its way across five more synapses as it moves from the back of the
brain, called the occipital cortex, to the frontal cortex. At each synapse, the
neurophysiological patterns is evoked by the visual image become progressively
more complex, the simple lines and edges signaled at the first synapse accruing
ever richer detail and associations as the visual
image moves closer
to the front of the brain.
Do you ever think you recognize someone
you miss in a place where they cannot be? When I’m
traveling, for a few milliseconds I often think that blond teenager I glimpse in the airport is my son Brandon
before I realize that’s impossible.
By contrast,
smell is an older, more primitive sense, with little potential for erroneous
associations because it takes a quicker, unfiltered route into consciousness. It’s only one synapse away from the nose to the amygdala, a nodal point that directly routes incoming sensory information
in all forms to the higher centers of association in the cortex. This explains why our associations with odors are so strong and memorable. The
other day, my husband suddenly realized why he had had an irrational hatred of
bluejays all his life. As a seven- year-old, he had painted a bluejay model in
a confined place with a foul-smelling paint that had made him vomit!
Using
neuropeptides as the cue, our bodymind retrieves or represses emotions and behaviors. Dr. Eric Kandell and his associates at Columbia University
College of Physicians and Surgeons have proved that biochemical change wrought at the
receptor level is the molecular basis of memory. When a receptor is flooded with a ligand, it changes the
cell membrane in such a way that the probability of an electrical impulse
traveling across the membrane where the receptor resides is facilitated or
inhibited, thereafter affecting the choice of neuronal circuitry that will be used. These recent discoveries are important for
appreciating
how memories are stored not only in the brain, but in a psychosomatic network extending
into the body, particularly in the ubiquitous receptors between nerves and
bundles of cell bodies called ganglia, which are distributed not just in and near the spinal cord, but all the way out along
pathways to internal organs and the very surface of our skin. The decision
about what becomes a thought rising to consciousness and what remains an
undigested thought pattern buried at a deeper level in the body is mediated by
the receptors. I’d say that the fact that memory is encoded or stored at the receptor
level means that memory processes are emotion-driven and unconscious (but, like
other receptor-mediated processes, can sometimes be made conscious).
STATE-DEPENDENT MEMORY AND ALTERED CONSCIOUSNESS: OUR
PEPTIDES AT WORK
Back in my college
days, at one of the graduate seminars held in the psychology department of Bryn Mawr, I heard the psychologist
Donald Overton of Temple University,
who had documented a widespread phenomenon in
animals, which later proved to carry over to humans. A rat that learns a
maze or receives a shock while under the influence of a drug (which you can now visualize as an
external ligand that binds to receptors in the brain and body) will remember
how to solve the maze or avoid the shock most efficiently if the rat is
retested under the influence of the same drug. When we consider emotions as
chemical ligands—that is to say, peptides—we can better understand the
phenomenon known as dissociated states of
learning, or state-dependent recall.
Just as a drug facilitates recall of an earlier learning experience under the influence of that same drug for the rat,
so the emotion-carrying peptide ligand facilitates memory in human beings. The
emotion is the equivalent of the drug, both being ligands that bind to
receptors in the body. What this translates into in everyday experience is that
positive emotional experiences are much more likely to be recalled when we’re in an upbeat mood, while negative
emotional experiences are recalled
more easily when we’re already
in a bad mood. Not only
is memory affected by the
mood we’re in, but so is actual
performance.
We’re more likely to be helpful to others and perform in
altruistic ways when we are experiencing a good mood. Conversely, hurt the ones
you love enough times, and they will learn to feel threatened in your
presence and remember to act
accordingly. It
doesn’t take an expert in emotional theory to recognize that
there is a very close intertwining of emotions and memory. For most of us, our
earliest and oldest memory is an extremely emotion-laden one.
One extremely
important purpose of emotions from an evolutionary perspective is to help us decide what to
remember and what to forget: The cavewoman who could remember which cave had
the gentle guy who gave her food is more likely to be our foremother than the
cavewoman who confused it
with the cave that held the killer bear. The emotion of love (or
something resembling it) and the emotion of fear would help secure her
memories. Clearly, just as drugs can affect what we remember, neuropeptides can
act as internal ligands to shape our memories as we are forming them, and put
us back in the same frame of mind
when we need to retrieve them. This is learning. In fact, we have shown that
the hippocampus of the brain, without which we can not learn anything new, is a
nodal point for neuropeptide receptors, containing virtually all of them.
Emotional states
or moods are produced by the various neuropeptide ligands, and what we
experience as an emotion or a feeling is also a mechanism for activating a particular neuronal
circuit—simultaneously throughout the brain and body—which
generates a behavior involving the whole creature, with all the necessary physiological changes that behavior
would require. This fits nicely with Paul Ekman’s elegant
formulation that each emotion is experienced throughout the organism and not in
just the head or the body, and has a corresponding facial expression. It’s part
of the constellation of bodily changes that
occurs with each shift of subjective feeling.
Is there one kind of peptide
that is specific to each emotion? Perhaps.
I believe so, but we have a way to go to work this out. In the case of
angiotensin, a classical hormone that is also a peptide, we have a good, simple
example of the relationship between a neuropeptide and a mood state, and how
that mood state can coordinate and
integrate what happens in the body with what happens in the brain. It has long been known that angiotensin mediates thirst, so if one implants
a tube in the area of a rat’s brain that is rich with angiotensin receptors
and drops a little angiotensin
down the tube, within ten seconds the rat will start to drink water, even if it
is totally sated with water. Chemically speaking, angiotensin translates as an
altered state of consciousness, a mood state that makes humans and animals say, “I want a glass (or a
trough) of water.” In other words, neuropeptides bring us to states of consciousness and to alterations in those states. Similarly, angiotensin applied to its
receptors in the lung or kidney
will
also
cause bodily changes, all of them aimed at conserving water. For example, there will be less water vapor
in each breath exhaled from the lung and less water in urine excreted by the
kidneys. All systems are working together toward one goal—more water—which has
been dictated by an emotion (or what the experimental psychologist would call a
“drive state”)—that of thirst.
Does the sum of
the peptide secretions in our brains and bodies—our emotional state—bias our
memory and behavior so we automatically get what we expect? Now, that is an
interesting question that I will consider next.
CREATING OUR OWN REALITY, REALIZING OUR OWN EXPECTATIONS
There is no
objective reality! In order for the brain not to be overwhelmed by the constant
deluge of sensory
input, some sort of filtering
system must enable us to pay attention to what our
bodymind deems the most important pieces of information and to ignore the
others. As discussed, our emotions (or the psychoactive drugs that take over
their receptors) decide what is worth paying attention to. Aldous Huxley was on
to this in The Doors of Perception when
he referred to the brain as a “reducing valve.” He was also on the right track
when he assumed
that what got through to command headquarters was just a tiny trickle of what could be absorbed at any
given moment.
Since our
sensing of the outer world is filtered along peptide-receptor-rich sensory way
stations, each with a different emotional tone, how can we objectively define what’s real and what’s
not real? If what we perceive as real is filtered along a gradient of past
emotions and learning, then the answer is we cannot. Fortunately, however,
receptors are not stagnant, and can change in both sensitivity and in the
arrangement they have with other proteins in the cell membrane. This means that
even when we are “stuck” emotionally, fixated on a version of reality that does
not serve us well, there is always a biochemical potential for change and
growth.
Most of our
bodymind attentional shifts are
subconscious. While neuropeptides are actually directing our
attention by their activities, we are not consciously involved in deciding what
gets processed, remembered, and learned. But we do have the possibility of
bringing some of these decisions into consciousness, particularly with the help
of various types of intentional training that have been developed with precisely this goal in mind—to increase our
consciousness.
Through visualization, for example, we can increase the blood flow into a body part and thereby increase
the availability of oxygen and nutrients to carry away toxins and
nourish the cells. As discussed, neuropeptides can alter blood flow from one
part of the body to another—the rate of blood flow is an important aspect of prioritizing and distributing the finite resources available to our body.
Norman Cousins
once told me that he had gotten over a broken elbow, which he had suffered
while playing tennis, and got back on the court in record time simply by
focusing for twenty minutes each day on increasing the blood flow through the
injured joint, after his physician explained that poor blood supply to the
elbow was why injuries to this joint healed slowly.
But I don’t want to leave you with the impression that I am advocating that the unconscious must always be
brought to consciousness in all successful therapies. In fact, the unconscious
mind of the body seems all-knowing and all- powerful and in some therapies can
be harnessed for healing or change without the
conscious mind ever figuring out what happened. Hypnosis, yogic breathing, and
many of the manipulative and energy-based therapies (ranging from bioenergetics
and other psychotherapies centered on body work to chiropractic, massage, and therapeutic touch)
are all examples
of techniques that can be used
to effect change at a level beneath consciousness. (Based on the drama and
rapidity of some therapeutic
transformations, I believe that
repressed emotions are stored in the
body—the unconscious mind—via the release of neuropeptide ligands, and that
memories are held in their receptors.) Sometimes transformations occur through the emotional catharsis common to
the many bodymind therapies that focus on freeing up emotions that have gotten
lodged in the psychosomatic network, but not always.
For example, the
famed psychiatrist and hypnotherapist Milton Erickson addressed the subconscious minds of several
young women who, although
having been subjected to all kinds of hormone injections, remained completely flat-chested. He suggested to them while
they were in a deep trance that their breasts
would become warm and tingly and would start to grow. Although
none of them could remember anything that happened in his office, all
grew breasts within two months, presumably because Erickson’s suggestions
caused the blood supply to their breasts to increase!
Emotions are constantly regulating what we experience as “reality.” The
decision about what sensory information travels to your brain and what gets
filtered out depends on what signals the receptors are receiving from the
peptides.
There is a plethora of elegant neurophysiological data suggesting that the
nervous system is not capable of taking in everything, but can only scan the
outer world for material that it is prepared to find by virtue of its wiring hookups, its own internal patterns,
and its past experience. The superior colliculus in the midbrain, another
nodal point of neuropeptide receptors, controls
the muscles that direct the eyeball, and affects which images are permitted to
fall on the retina and hence to be seen. For example, when the tall European
ships first approached the early Native Americans, it was such an “impossible”
vision in their reality that their highly filtered perceptions couldn’t
register what was happening, and they literally failed to “see” the ships.
Similarly,
the cuckolded husband may fail to see what everyone else sees, because his
emotional belief in his wife’s faithfulness is so strong that his eyeballs are
directed to look away from the incriminating behavior obvious to everyone else.
As
investigations continue, it is becoming increasingly apparent that the role of peptides is not limited to eliciting
simple and singular actions from individual cell and organ systems. Rather,
peptides serve to weave the body’s organs and systems into a single web that
reacts to both internal and external environmental changes with complex, subtly
orchestrated responses. Peptides are the sheet
music containing the notes, phrases, and rhythms that allow the
orchestra—your body—to play as an integrated entity. And the music that results
is the tone or feeling that you experience subjectively as your emotions.
March 1981: During
one of my many nightly
visits to my father at the VA hospital during the course of
his treatment for lung cancer, he looked from his bed and asked sardonically,
“Well, how’s the cure coming?” Embarrassed and saddened, I couldn’t meet his gaze. I had visited
the lab earlier
that day and found that his cancer, which had mutated and
returned to his body since remission a year ago, was proving resistant in vitro
to all known chemotherapeutic agents. My own attempts to understand his disease
and find a cure were looking equally as hopeless.
“It’s going well,” I lied, trying
to give him the hope I myself did not have, hope that seemed to me to be his
last shot at somehow effecting a miracle
cure of this deadly disease.
“The results from
the lab will show something is going to work, I’m sure
of it.” And then changing the subject, I said, “Look
at what Vanessa
made at school for you!” He seemed
to brighten up as I brought out a rainbow mobile that my five-year-old daughter
had sent along to decorate Grandpa’s room.
He was dozing off as I hung this symbol of hope above
his bed, and, with a heavy heart,
I whispered a soft apology:
“I’m sorry, Dad, science
still doesn’t have the answer.”
I knew that even after decades of intense research
there essentially had been no treatment advances beyond the highly toxic drugs
developed before 1965. What I didn’t know was how fiercely the cancer establishment
would resist the efforts of an outsider—me—to come up with new ideas for
treatment. This would be my first personal exposure to the intransigence of
old- paradigm thinking, and an experience so profoundly disillusioning that it made it almost easy for me to slip the traces
of my own intellectual harness. I was about to enter a very long, dark tunnel
of despair, and then, to my joy and astonishment, make my way toward a light
that would illuminate a whole new world of thought.
8 TURNING POINT
SHIFT
It was inside
the NIH cafeteria, on a winter afternoon in early 1982, that the last sparks of my faith
in the Palace, the power boys, and the prevailing paradigm sputtered and began to
die. There I sat at the lunch table, my salad wilting on the plate,
halfheartedly engaged in word-to-word combat
with an alpha male scientist over who would
get the credit for the what, when,
and how of the work we had
done together. In my ninth month of pregnancy with Brando, my marriage turning
sour, and my father dead—I wanted to just get up and walk away.
Until the death of my father
in 1981, in spite of the lessons
I’d learned from the Lasker incident (and perhaps
partially because of them), I had been willing to wrestle over rewards, to do
whatever it took for the chance of more citations, and to grab turf from my competitors. I was as willing as the next
guy to split one research project into as many self-contained papers as
possible, selfishly disregarding the needs
of researchers who might benefit
from getting the news
all at once. I had learned to play the game of science, and it had brought out
a suvivor’s instinct in me. Stopping short only at sacrificing my personal
integrity and honesty, and still holding strongly to my ideal of science as
truth-seeking, I had gotten good at
swimming with the sharks.
But when Dad
died, I came up for air. For the first time in my career, I was forced to see a
connection between the science I did and the people whose lives depended on it.
Real people, not just statistical ones, were dying from diseases that lacked
effective cures, and now one of these real people was my own flesh and blood.
With this new perspective, the chicanery of politics, the sportsmanship, the
ego battles all receded into the background, and a deeper sense of purpose
emerged to guide me.
The diagnosis of
my father’s lung cancer was made in February 1980. It was the first time anyone
in my family had been diagnosed with a life-threatening disease, and the news
hit me hard. Even more shocking, however, was learning that he had a particular kind of cancer that I knew quite a bit about. Small-cell, or “oat
cell,” carcinoma, named from the cancer cells’ resemblance to tiny oats
under
a microscope, is a nasty mutation of the body’s natural processes. The tumors
grow rapidly and spread quickly, metastasizing throughout the body and usually
causing death within a very short time. Of the four major types of lung cancer
a person can develop, about 25 percent are small-cell, and almost 100 percent
of those who get it are, like my father, continual, heavy cigarette smokers.
As soon as I heard the diagnosis, I immediately started
phoning around, asking for the name of the top small-cell
cancer clinician at the Palace. The name I came up with was that of a major
player who ran a titanic lab inside the NIH’s National Cancer Institute. In one of the many instances of synchronicity that seem to mark my life on a regular
basis, this same doctor had been trying to
phone me for the past month, but I had never been able to find the time to answer his calls.
But now he went straight to the top of my list. Although
it was a Sunday when we got
the diagnosis, I called him at home to explain the situation and ask for his help. As a favor, he agreed to
admit my father to his current trials, even though Dad’s age exceeded the
protocol’s limit and his outcome wouldn’t be counted in the trial data. But none of that mattered
to me. Even if there was only a one-in-a-million chance that the latest experimental
chemo-cocktail might offer a permanent
cure, we now had hope where there had been none before,
and I was grateful.
The doctor and I
then got down to business. He had been phoning me because he wanted to follow
up on research that showed his small-cell cancer cells were secreting neuropeptides. I, too, knew of this research, done in the 1960s by Dr.
Rosalind
Yalow, a woman who had won the Nobel Prize for her findings. Since then, however,
many new neuropeptides had been identified, and what the cancer doctor and his lab wanted was
an updated “peptide profile,” showing exactly
which of the newly discovered peptides were being secreted. He knew
that it there was going to be a cure for small-cell
carcinoma, it had to come from
a better understanding of the nature of these cells and how they functioned.
Only then could we define the precise molecular effects and devise
a rational, effective
treatment. He also knew my lab was state-of-the-art in the peptide field, and
was probably the fastest route to getting the answers he needed.
It was a
prototypical Palace transaction, this agreement of one lab to collaborate with
and answer questions being raised by another—an example of the Palace in its prime, of
crème-de-la-crème science. Had I been at a university when this request came
up, I would have first needed to write a proposal for a grant, then submit it, and then wait around
for the funding
cycle to spin around
in
my favor. Even then, I would have had only one out of five chances of being
allotted the money I needed. If I’d been conducting research in the business world, I would have
needed to convince the shareholders or vulture capitalists of its profitability
before anything could happen.
But at the
Palace we had only to do the verbal equivalent of a handshake over the phone,
and we had a deal. My father
would be included
in the cancer doctor’s clinical trials, and I would help the doctor’s
lab identify the peptides being secreted
by the cancer cells. Having served in World War II, Dad was
given a bed in the Veteran’s Administration Hospital in downtown Washington,
D.C., one of the few beds reserved for the trial patients.
Within a few days, a hundred
tiny test tubes
arrived at my lab, each containing a minute, pellet-sized
ball made from a different cell line, which is a sample of cells taken from a
patient and arduously grown in a dish. These cell lines included several different kinds of lung cancer from
scores of patients. I proceeded to prepare
a peptide extract
of each pellet,
a precise job of adding
a hot acid solution just so. Then I transferred the contents of each
test tube into ten other test tubes,
giving me ten samples for each cell line of lung cancer,
for a total of one thousand
test tubes. I planned to look for ten different peptides, handling the
endorphins myself and giving the bombesin to my former postdoc, Terry Moody,
who was now at George Washington University on the other side of town, but who had
done the receptor-mapping research on bombesin while he was still in my lab. The other eight projects I farmed out to peptide buddies who I knew were set up to make quick searches
for specific peptides. What better way, I
reasoned, to accomplish the goal of understanding these cancer cells than to measure
everything possible, a tactic not uncommon among
researchers hot on the trail,
often referred to as a “fishing expedition.” Time was short, and my dad’s life
was depending on my being able to make a quick run. I prayed for a swift
turnaround.
Certainly, a new
approach to the treatment of cancer was—and still is— desperately needed.
Although the cancer establishment has been trying to crack this disease for
years, it continues to kill more people every year, often a slow and painful
death made even more excruciating by toxic treatments. The highly toxic
chemotherapeutic drugs developed in the 1950s kill all rapidly dividing cells
in the body, which means not only cancer cells but many kinds of healthy cells
as well. Unfortunately, the immune system, the body’s natural defense system
against cancer, is itself composed of cells that are rapidly dividing. So both
the disease and the protection
against the disease get zapped.
In the Cancer
institute’s trials for small-cell lung cancer, there was only one patient who was still
alive five years
later. Most chemotherapy patients were dead
within two years. State-of-the-art chemotherapy in those days was nothing more
than different combinations of the same old toxic drugs given on different
schedules. If my father was going to survive, I knew that a new approach, a major
breakthrough in understanding and treating this disease had to happen.
But I was hoping the chemotherapy would buy him some time—enough time for me to do the necessary work.
Dad rallied
right after the chemotherapy, and within weeks
came back from the near-dead to looking nearly
normal. He had had a remission, as expected, but would soon have a relapse,
which was also expected. I knew this, but I couldn’t bring myself to tell him
or my mother. I believed, intuitively, that he needed all the hope he could get,
in spite of his natural tendency toward skepticism. For this reason, I chose to
emphasize only the “good news” during my daily visits to fill him in on how the
race to find a cure for his cancer was progressing.
In my lab,
however, I was not feeling so optimistic. As part of my quest to understand his
disease, I dove into the oncology literature with a million questions. Why were
these strange small cells, which divided rapidly, so full of peptides? why were
the cells so unlike those typically found in lung tissue? I thought that it only
i could answer these questions. I’d be able to save my father’s life.
Dad was far from
convinced. As his condition worsened, and the relapses followed the remissions, he stoically watched
my frantic intellectual activity with detached amusement. My father was a man of the
world, an artist, a big- band jazz arranger, a sophisticate, a skeptic—in short, no easy believer in miracle cures. What he wanted most of
all was to be made as comfortable as possible
while enduring the intense nausea brought on by the chemotherapy, and I did my best to see that his doctors
and nurses were providing him with everything available.
When the data
came in from my fellow peptide researchers, I entered it on a big spreadsheet and raced over to the
cancer lab. None of us knew which cancer had been in what test tube, since
ignorance (known as “being blind to the protocol”) was a necessary part of the
scientific etiquette. Now, bending over the numbers with one of the lab
director’s postdoes, I watched intently as the name slots were filled. It
didn’t take long to see what was happening; Every one of the tubes containing
small-cell cancer cell lines was characterized by a detectable— and sometimes
extremely high—level of the peptide bombesin.
Bombesin! I got a chill remembering that Terry Moody and I had taken this
very
peptide from obscurity to molecular neuropeptide stardom. First we had located
the bombesin receptor, and then we’d gone on to use the bombesin antibodies to
find the peptide itself inside neurons in the brain.
Until this
breakthrough, I’d been running on wild romanticism, fueled with hope and fear for my father’s
fate. But the new finding
brought us much closer
to actually figuring out what makes these cells replicate so fast. If we could
understand the mechanism of the rampant out-of-control growth, perhaps we could find the key to stopping it.
Identifying the substance that stimulated the growth would put us in a good position to find an antagonist
to block that action. I now
seriously began to think we had a chance to find a treatment before it was too
late.
I welcomed the
chance to work with Terry again, so enjoyable and productive had our work been before, and we quickly
set about trying to answer the
question. Was bombesin’s presence the key to the cancer cells’ wild, rapid
proliferation? This was pure conjecture, but most cell “growth factors”
had finally turned out to be peptides when they had been purified and
chemically identified. Peptide growth factors acted at receptors in the
cellular membrane, causing cells to divide and then multiply as part of their
normal, healthy development. Insulin was one of these peptides; epidermal
growth factor (EGF) was another. For obvious reasons, growth factors had become
an area of intense interest in cancer research. If bombesin was a growth factor secreted
by the tumor cells to promote
their own growth, it could explain the mechanism by which the lung cancer cells were
proliferating so rapidly. When our research showed that the cancer cells were
not only secreting bombesin but were presumably acted on by it as well, since
they had bombesin receptors on their surfaces, we thought we had identified the
mechanism. Bombesin, it turned out, was not only a growth factor but an
autocrine growth factor, a substance secreted by the very cell upon which it
acts.
We dutifully
communicated our findings to the cancer lab director. Two weeks later, one of his researchers called
me and, with an audible tremble in his voice, explained how bombesin had made
his cell lines grow faster! He was confirming our hunch that the presence of
bombesin and bombesin receptors on these cancer cells must be why they were
growing out of control!
I was thrilled
to include his confirmation of our findings at the end of our paper describing the bombesin—small-cell
cancer connection, which I rapidly wrote up tor
Science. I cited it as a
“personal communication” from Adi Gazdar, a researcher at the cancer lab—the standard
way of acknowledging research that
has not vet been published. I submitted the paper, putting
Terry as first
author and the Cancer Institute lab chief as last author, with the rest
of us distributed in between. When it appeared, the cancer lab director felt
that he had been scooped by my use of his lab researcher’s data, which could
conceivably enable his competitors to use the information and move in on his
territory. My own feeling was that time was of the essence. The lung cancer
community urgently needed this
information, and the sooner it got out, the better. In my mind, playing the
political game was secondary to making our findings available to as wide an
audience as possible, and I didn’t care at all who got the credit.
Meanwhile, my
father’s condition had seriously worsened. He’d undergone a bone marrow transplant, a very painful
surgical procedure used when patients are not responding to normal
doses of chemo. Immune cells are extracted from their sources in the bone
marrow and refrigerated for later reinfusion after the patient undergoes
massive doses of killer chemotherapy. The assumption is that the bone marrow
has no cancerous cells and so can be reintroduced after the system has been
“cleaned” by chemotherapeutic drugs to act as seeds to grow a new immune
system. What’s left of the patient after the chemotherapy is expected to become fertile ground for the
new immune cells to take root and flourish.
In my father’s
case the strategy hadn’t worked. Possibly the chemotherapy hadn’t killed all
the cancer cells, and those remaining continued to grow. Or, as we were to explore in later research,
perhaps there were precursor immune cells from the bone marrow that were
themselves implicated in the cancerous growth, and so continued the disease
process once they were returned to the body after chemotherapy.
Even though
this latest round of chemo had caused him to lose all his hair and appear
haggard, he was still recognizable as his jaunty, jokecracking self. I remember
plying him daily with megadoses of vitamin C in hope of countering some of the
toxicity from the drugs. At one point, I even suggested bringing in a
controversial cancer doctor with an alternative treatment I’d read about. But
in spite of my upbeat efforts. Dad was rapidly losing interest in exploring new
avenues that might lead to his recovery.
Gradually, he was
being moved closer and closer to the nurses’ station, not a good sign since it
meant they wanted to keep a more constant vigil. Then came a heavy blow, the
news that the cancer had spread to his brain and would require radiation
treatment. Until then, Dad had kept his spirits relatively high, even endearing himself to the nurses by constantly playing
jazz riffs on his guitar.
Now
with this latest diagnosis, he took a swift and sure emotional dive. Dad was an
intellectual, an artist, and the news that the cancer was destroying his brain
demoralized him, destroying what little hope he had left. Nonetheless, he
proceeded with the radiation.
On the seventh
day of the radiation treatment, I noticed a distinct shift in my own feelings,
from hopefulness to a numbing emptiness. Although my brain was lagging behind
in acceptanc’e. I knew intuitively that my father wasn’t going to make it.
That night when he said good-bye to my mother, he made an unusual request.
I hadn’t gone with her to the hospital that day, because once I’d given up
hope, I couldn’t face looking him in the eye.
“Go to Candy’s.”
he repeatedly told her, as she held his hands and assured him she would. Dad
knew he was going to die that night, and he wanted my mother to be with me, which she was, when the final phone call came around 2
A.M.
My father died almost a year to
the day after being diagnosed. When went to the
VA hospital to pick up his effects, I noted a half pack of cigarettes in the
drawer next to his hospital bed, not a surprising find considering how heavily
addicted he had been. As I was leaving, an administrator gave me an American
flag to drape over his coffin at the funeral. But remembering his frequently
expressed opinion, “War is for idiots,” we had no intention of using it.
Instead, it went into storage
until some years
later when, remembering his fun-loving nature
and still missing him terribly, we brought it out to cover our bounteous Fourth
of July picnic table.
As for my
research, I hadn’t moved quickly enough. Although we now had some further understanding
of what was going on in this disease, we hadn’t had time to devise a treatment for it. Instead of a cure, I had another paper in Science
—and
another enemy. The Cancer Institute lab chief was furious at how I’d squandered
the hot finding about the growth of the cancer cells by releasing it, in his
eyes, prematurely. I’d done the unspeakable, packing our paper with data that
any self-respecting scientist would have spun out over three or four papers, thereby
increasing the number of publications, to say nothing
of all the chances to get
cited.
IT WAS AT this juncture in the episode that I
found myself at an NIH lunch table,
sitting opposite my onetime collaborator, verbally wrestling with him over
control of the research. As the power boy sat across from me making demands, I
was in no position to mount an effective defense, nor did I want to. In tough tones, he told me that he’d prefer to cut me out altogether, and deal only with
Terry. This was his arena, he told me in no uncertain
terms, and I needed to understand that. After all, he was the chief, and if I
was a good girl, maybe I would be considered for the position of
research associate on future projects.
It was déjàvu, a
replay of my final conversation with Sol before trading Hopkins for the Palace.
Once again, I was being told by a powerful
male scientist not to work on a part of the research that we had begun
jointly. Some things, it seemed, were too important, too prestigious for
acknowledgment to be shared, and from his viewpoint, obviously, the
bombesin-small-cell cancer connection was one of them.
Of course, he could justify his reasons for playing the cards this way.
Evidently, I had added insult
to injury when, with the help of his associates, I had checked out an obvious
prediction that bombesin
levels should be elevated
in the blood of patients with small-cell lung cancer. We had cut our teeth on
peptide blood assays and could do them in our sleep, so it was a natural and
easy confirmation. I communicated our results to the cancer lab director,
letting him know that I intended to get off a brief paper to the Lancet, a prestigious British medical
journal, suggesting that the symptoms of patients with this type of lung
cancer, such as itching, low temperature, and loss of appetite, were due to the
surplus of bombesin in the bloodstream.
It was this move that was the final straw, causing
him to reconsider any
further collaboration with me. To this day, I don’t know if the real source of
his problem with me was that he didn’t trust my work, or that he saw me as
invading his turf, messing with his plan of slowly spinning off our discovers
into as many articles as possible. Later, I suspected that he was partly
motivated by a feeling that it was politically unwise to appear
with me on too many papers, a speculation that was supported when he
ordered his name removed from the Lancet paper. When it was finally published, the paper had my name and the name
of my technician on it, with an acknowledgment to the Cancer
Institute lab.
I remember
thinking about all this as I sat across from my lunch table combatant, barely
listening as his booming voice harangued me for well over an hour. I also
remember feeling the late-term stirrings of my unborn child, which made me
oddly peaceful in the midst of this ordeal. Perhaps the message that new life was on its way gave me strength
and afforded me some distance from the
attack I was now being subjected to.
The next
morning, I received a four-page, single-spaced letter from the cancer lab director
that read like a formal
contract, spelling out exactly who would do
what,
when and where, in regard to further research. I read it with a dulled
responsiveness, having no intention of ever bothering to reply. Clearly, my ex-
collaborator believed I had been poaching on his turf, and I believed, just as
clearly, that his territorial maneuvering, driven by a self-aggrandizing motive
to get as much credit for the research as he could, was the stuff that kept
medical science from finding desperately needed treatments. Mv father was dead,
and I no longer had a shred of a reason to stay in the
cancer doctor’s good graces.
I returned to my
brain maps, my receptors, my peptides. What had been a thrilling and meaningful
search for answers to the questions of why these lung cancer cells were full of
peptides, why they didn’t fit the profile of other lung cells, was now being shelved. I fantasized that someday it would
be resurrected, perhaps in a time when cold-hearted ambition mattered less than
a genuinely motivated search for the truth. But for now, I let it go, thinking
of it only in those moments when I remembered, with an ache, my father
and how I had tried in
vain to save his life.
CONNECTION
My weariness and disillusionment would soon fade,
however, as I began a new intellectual journey, one that started with a casual social
encounter, picked up steam as it
involved me in yet another major quest for a disease cure, and had such
momentum that it sustained me through criticism and adversity that would make
what I’d already endured look minor. I met Dr. Michael Ruff in the fall of 1982
at the now-defunct Palace bar, a clubhouse and watering hole for brain- wean scientists, located in a donated
stone house right off the campus grounds. Next
to the cafeteria, it was the most interdisciplinary spot in the Palace, a fruitful place where the usual
boundaries dropped away, and the talk flowed
freely.
I rarely went
there, but late one afternoon, several months after my separation from Agu had
been formalized, I stopped by on a psychic bunch. With my new baby tucked
securely into a carrier strapped on my chest. I certainly didn’t feel very
glamorous or sexy. But I had a premonition as I climbed the stairway to the
main room that I was about to meet someone very interesting.
I found myself
gravitating toward the end of the bar, where two young, good- looking postdocs
were holding forth.
A few flashes of friendly
eye contact passed between
us, and I could tell that they had recognized me. “That’s Candace Pert,”
I could see one mouth to the other, Soon we were all talking.
Michael Ruff and
Rick Weber, I found out, had studied immunology in graduate school together,
and were now getting some seasoning as postdoctoral students at the Palace.
Mike told me later that he’d remembered seeing me on a TV science documentary,
talking about how endorphins from the testes caused the orgasmic spasms of the vas deferens. I have to admit that my
feminine ego soared as I contemplated playing the alpha, older, wise-woman
scientist to these betas. But what really excited me was the fact that both
guys were immunologists. Because
I’d had an idea in the back of my mind for a long time
—a
notion that schizophrenia might be an autoimmune phenomenon—I’d been hankering
for a congenial immunologist to grill.
Rick’s specialty
was the study of the chemistry of antibody molecules, those spongelike
substances made by certain immune system cells to recognize and eliminate
invading pathogens (disease-causing agents) that threatened the organism. Rick
was eloquent in his description of how these antibodies vibrated and changed
shape as they encountered the bacteria, virus, or tumor cells, latching on to them
and escorting them out of the system. We all had a good laugh when he described the scene in the movie Fantastic Voyage where Raquel Welch
enters the bloodstream and is engulfed by a swarm of antibodies, each perfectly
shaped to cup on to her amazing breasts.
Michael, who
seemed quieter, more reserved, was interested in the cellular portion of the
immune system, in particular the highly mobile scavenger cells known as
macrophages, whose function is to keep the blood clean of debris left over from
the battle to kill invaders. He talked about how “eating dirt” was but one
function of these cells. They also played a key role in repairing the body
fabric, manufacturing tissue when needed and orchestrating a chemical and
cellular cascade that resulted in a healing response. Michael was beginning to
question how they did all of this without some ability to communicate with each
other or with the rest of the body—a concern that didn’t bother other
immunologists in the least.
Like Michael. I,
too, had some radical ideas stewing on the back burner of my imagination. One
of these involved my hunch that schizophrenia might be the result of an
autoimmune response, which is what we call the phenomenon in which the immune cells
go awry and attack part of the organism itself rather than the invaders
they are supposed
to attack. In schizophrenia. I theorized, the immune cells were secreting antibodies that targeted
brain cells via their
receptors. Throwing caution to the winds, and trusting my sense that Mike and
Rick were young and open enough to follow me. I put it right out: “I want to find
a
real cure for schizophrenia.” I announced, noticing their attention shift
rather dramatically. “My idea is that the disease is caused by antibodies being
made against the brain-cell receptors.”
There was a thoughtful silence as they pondered this possibility.
“Do you guys know if there’s a way to test this?” I asked more tentatively.
We agreed on the
spot to explore the hypothesis. A first step would be for me to teach them brain-receptor science and
for them to teach me immunology, a project we began that afternoon in the bar!
I didn’t know it then, but the deal we had just struck marked the beginning of
a collaboration that would bear much fruit
by merging our two fields to bring about a new approach to healing and disease.
The research we would do would circle out from schizophrenia, leaving it temporarily behind
as we explored the connection between nervous and immune systems, mind and body, as it pertains to cancer and
AIDS, returning only years later to
the question of schizophrenia.
Soon after our
meeting at the clubhouse, the three of us took to hanging out together. One
afternoon, we were bouncing up and down in Rick’s open Jeep when he pushed a
journal reprint toward me.
“Look at this,
Candace,” he said. “Its written by my buddy Ed Blalock from the University of
Texas.”
“What is it?” I
asked, since I was jiggling around too much to be able to read the title.
“He’s found immune cells that make endorphins.”
“Really?” I
said, hesitating while I let this astounding piece of information settle into
my consciousness. “Does this guy know what hes doing?”
“It looks rock solid to me,” Rick responded. “Read it yourself.”
Rick pulled
the Jeep over, and with both him and Mike leaning over my shoulder, I read the
paper. Blalock, an immunologist who had been in graduate school with both Mike
and Rick only a few years earlier, had been studying interferons, peptides that
are made by certain white blood cells known as lymphocytes. Like antibodies,
interferons have the job of fighting off invading pathogens and thus help to
preserve the integrity of the body. In his studies, Blalock noticed that
interferons sometimes mimicked the activity of hormones, an observation that prompted him to put the
lymphocytes in a dish and stimulate them to produce
interferons, so that he could see if they produced
anything else at the same
time. To his shock and surprise, he found the lymphocytes were also secreting
the mood-altering brain peptide endorphin, as well as ACTH, a stress hormone thought
to be made exclusively by the pituitary
gland, the main gland
in the endocrine system.
“My God!” I
exclaimed. “If this guys right, it makes the immune system look like a floating
endocrine system, a bunch of tiny pituitary glands!”
In our
excitement, we jumped rapidly to a possible conclusion: The immune system was
communicating not only with the endocrine system but with the nervous system
and the brain, as well, by using a chemical mechanism that consisted of the
neuropeptide endorphins and their receptors to code for information. But there
would be many steps—and about two years—between formulating this hunch and feeling confident enough about it to put it in print.
As the news of
Blalock’s discovery spread, very few of my colleagues shared my enthusiasm. They either ignored
Blalock or dismissed
him as wrong. This was to be
expected. Whenever something doesn’t fit the reigning paradigm, the initial
response in the mainstream is to deny the facts. To suggest that systems
historically defined as separate were actually interrelated was paradigm-busting
at its best! For a while after his discovery, wherever Blalock went, he heard
the whispered charges: “Sloppy work! Artifact! Dirty test tubes!” And they kept
up until the number of labs that had repeated Blalock’s observation grew too great
to ignore. What he had seen was no “artifact.” that is, something that was a product of the experiment itself. Finally,
in 1983, an editorial in Nature admitted
the presence of brain peptides in the immune system, but warned the scientific
community against those “radical psychoimmunologists” who might
prematurely interpret this work to mean that “no state of mind exists that is
not reflected by a state of the immune system.” Rick, Mike, and I embraced the
moniker with pride, proudly referring to ourselves as radical psychoimmunologists from then on.
But even while
the weight of the evidence compelled Blalock’s critics to accept the data,
those critics still had no intention of addressing how that data challenged the
ordained view of the body.
As a budding
radical psychoimmunologist who didn’t think twice about disregarding
traditional boundaries to get at the truth, I immediately plunged into
extending and exploring the implications of Blalock’s work.
Michael, whose
home base was the Dental Institute over at the NIH, moved into my lab
temporarily so we could do the work together. Rick joined us frequently. The
first idea we investigated was that if the immune cells were secreting
endorphins, there were probably opiate receptors on the immune cell surfaces. I
knew there had been numerous papers published claiming to show opiate receptors
on immune cells; one was even written
by Pedro Cuatrecasas,
my
former teacher at Hopkins. He had found opiate receptors on immune cells using the traditional grind-and-bind method to isolate the receptors, but his paper, as well as several others,
had been ignored because of various anomalies. Again, this kind of finding was
far out in front of what the current paradigm accepted. Receptors for brain
peptides on immune cells? What could that possibly
mean? You’d have to have been some kind of radical psychoimmunologist—a
scientific category that didn’t even exist when Pedro wrote his paper—to be
interested!
We decided to
take a more compelling route, one that would be harder for our colleagues to
ignore. We would prove our hypothesis through what is called a “functional assay,”
one that would elicit a specific and measurable activity, rather than one that simply showed
the receptor. The main question
we asked was: What function
of the cell changes as the result of binding?
As part of his work on tissue inflammation at the Dental Institute, Michael had studied a process known as chemotaxis, the ability of a cell to
pick up the “scent” of a peptide by the receptors on its surface, literally
getting on its track and
traveling toward where the peptide was most concentrated until it could bind
with the peptide, whereupon the peptide commences its job of ordering the
cell’s activities. We decided to use chemotaxis as a tool to demonstrate the
action of opiates and their receptors on immune cells.
To do this, we
chose ten different opiate drugs, including the various endorphins, and showed that immune cells chemotaxed to them in the same order of relative potency that they
bound to the receptor. Later, we extended this work and showed, using the same
method, that there were receptors on immune cells for virtually every peptide
or drug we had identified in the brain, such as Valium, Substance P, and many
others.
We published our
findings and moved to the next logical question, which was the inverse of the
one we’d just answered: If there were neuropeptides in the immune system, would
we find immunopeptides in the nervous system? Finding brain correlates of
peptides that had originally showed up in other parts of the body was what our lab had been doing for years, and so we decided to take a look. This time, working with Mike and
another immunologist, Bill Farrar, a collaborator from the Cancer Institute, I
chose interleukin-1 as our first target immunopeptide.
IL-1, as it’s
known in the jargon, is a polypeptide hormone produced mainly by macrophages in the immune system, and
is one of fifty or so identified peptides that mediate the inflammatory reactions
caused by injury,
trauma, or an
activated immune
system. In a molecular cascade,
IL-1 causes fever,
activates the T cells, induces sleep, and puts the body in a generally
healing state of being, allowing it to mobilize its energy reserves to fight
pathogenic intruders with maximum efficiency.
Sure enough,
there were interlenkin-1 receptors in many areas of the brain, the second immunopeptide receptor
found there. (The first to be discovered was Thy-1, short for thymus, and Rick
Weber and Joanna Hill and I had done the autoradiographic mapping that showed
its distribution pattern in the brain.) We weren’t at all surprised, but the
immunologists, who had previously known only about the presence of Il-1
receptors in the hypothalamus, where they had long been recognized as a cause
of fever, were quite puzzled by the finding that Il-1 receptors were also in
the cortex and higher brain centers (mainly on glial cells and the tough
membranes around the brain). Today we know that numerous— perhaps all—of the
peptides discovered by immunologists can be made in the brain under some
circumstances, and can act on receptors in the brain.
What we were now
seeing was astounding and very revolutionary. The immune system was potentially capable of both sending
information to the brain via immunopeptides and of receiving information from
the brain via neuropeptides (which
hooked up with receptors on the immune cell surfaces).
Our work confirmed Blalock
by pointing irrefutably to the existence of a chemical
mechanism through which the immune system could communicate not only with the endocrine system but with the nervous
system and the brain, as well. Previous work my colleagues and
I had done demonstrated quite convincingly that the brain communicated with
many other bodily systems. But the
immune system had always been considered separate from the other systems. Now
we had definitive proof that this was not the case.
POTENTIAL
It was in the
spring of 1983 that Michael and I decided we were in love. The many hours we
spent working closely together in the lab had certainly contributed to this happy state, but ours was more than an
intellectual merger. We had
recognized something in each other that promised a new direction, a common quest based on a desire to step outside
what was ordinarily accepted and
bring forth something greater, both personally and scientifically. This became our bond, which was to serve us well in the coming years when nothing
we
would do would be possible without the support and strength we gave each other.
I remember the
moment I realized that Michael and I had a future, although never in my wildest
imagination could I have guessed what that future would hold. I had taken to hanging out with some
frequency at the clubhouse, often meeting on a casual basis
with Mike, Rick, and other friends. Mike had been away from the lab for a week, and on
his first day back had arranged to meet me at our usual corner for an informal
update on the work we’d been doing together.
I looked up as he slid into the booth and noticed his eyes were wider, more
clear and deep, and he seemed present in a way I hadn’t notice before.
“Wow, Mike,
where have you been?” I couldn’t help myself from asking. “You look like a
different person!”
He smiled and in
his low-key way proceeded to tell me that he’d been at a week-long bioenergetic
workshop.
“It was great,”
he responded enthusiastically. “We did all these exercises and made all these
noises. I can’t believe how much better I feel!”
Bioenergetics, he went on to tell me, was a kind of alternative therapy that
had been created by Alexander Lowen and inspired
by Wilhelm Reich.
Now, this was hardly a subject you’d expect to hear two Palace denizens
deep in conversation about, especially since Reich had been banned from the
realm of “real science” for his wild and crazy experiments with human sexual
energy— but I was fascinated and
pressed for more details. Bioenergetic therapy, Mike continued, made use of
various physical postures and exercises to access deeply stored emotional
traumas or blockages. The theory was that these emotions are trapped in the
physical body and can only be released physically, through movement accompanied
by loud, emotive expressions. The result was a freer, more abundantly flowing
sense of energy, something I was certainly seeing manifested before me in
Mike’s transformed appearance.
As we talked, I shared with him some of my own formal
and informal personal
excursions into the mind-body experience. One of these had occurred in 1977,
when I took Est training at the recommendation of a colleague at NIH. Est
personal-growth seminars were popular in the seventies, and were presented as a
two-weekend affair with as many as two hundred people crammed into a hotel
banquet room, literally sequestered for long stretches
of time with few breaks.
Although
I had a lot of skepticism at first, I decided to throw myself into the
training, intending to get the full experience and then make up my mind
afterward. A team of sensitive
if domineering trainers
led us through the paces,
from
guided visualizations to confrontational dialogues, and on to mind- boggling
explorations into the nature of reality. At one point, I witnessed a woman’s
physical body change. As she re-experienced an incest trauma buried for years,
the hunched shoulder she’d had since childhood appeared to spontaneously
transform itself, healing before our eyes.
I emerged from
the training with one conclusion: “God is in the frontal cortex!” As the part of the brain that gives us the ability to decide and plan for the future, to make changes, to exert
control over our lives, the frontal cortex seemed to be the only way I could
explain what I had seen and experienced. It seemed to me to be the God within each of us.
I struggled over the next few
weeks to integrate that remarkable experience, trying to transplant the sheer poetry of it into my
scientific mind-set, while Agu watched with suspicion and alarm. In retrospect,
I realized that what had happened to me during the training was that, for the
first time in my life, I had directly experienced my own raw emotions. The
sleep and food deprivation had broken down my defenses, putting me in touch
with how I really felt—my sadness, loneliness, anger, as well as my joy and
love for people. I was left with a new freedom to feel and a new faith in the future, both of which empowered me
during the days of the Lasker flap and the
period of ostracism that followed.
I was beginning to realize that Mike, like me, was willing to allow his life to be broadened and enriched by the
science he did, exploring in real life what he
was seeing under the microscope, a rare quality in a scientist,
especially at the Palace. The idea that the mind and body could he treated as a
whole, that the emotions could be accessed through the body, not just the mind,
for healing, and that the result of this could vastly improve the health of the
organism appealed to our deepest instincts.
That afternoon,
it dawned on me that I’d found a true companion, a soul mate, and maybe even a
co-conspirator with whom I could explore a whole new and exciting frontier. The
feeling, it turned out, was entirely reciprocal, and soon afterward, we began
to date. It wasn’t long before Michael and I became an “item,” demonstrating by our relationship a union of two separate
disciplines that would soon evolve into a whole new field of science,
one that would dramatically bridge and heal the mind-body split that had been
entrenched in Western medicine for over two hundred years.
My own naturally evolving awareness made me ripe for the next radical
shift in my consciousness. This occurred one day as I was helping Michael clean
out the trunk of his car, and I came across a copy of Norman Cousins’s Anatomy of
an Illness. I took the book home and, in
one sitting, practically inhaled it, so compelling was the thesis and so
closely did it resonate with my own nascent thinking at the time. Cousins, the
editor of a major literary magazine, The Saturday Review, had been diagnosed
with a life-threatening illness, an experience
that had led him to question the whole foundation of Western medicine.
Although not a doctor himself,
he’d had a few brushes
with the medical establishment
as a patient, and had come to some rather sensible conclusions about its
shortcomings. Rejecting what little help was offered by his doctors, Cousins
had checked out of the hospital and checked into a hotel, where he holed up
with an assortment of Charlie Chaplin videos and literally laughed himself back to health.
He had felt, intuitively, that what the body needed was
the life-affirming, joyous experience of laughter. What he was suggesting from this experience was that state of mind,
thoughts, and feelings, all of which were completely ignored by the medical
model, did in fact play a major role in his recover. He even postulated that
the laughter had triggered a release of endorphins,
which, by elevating his mood, had somehow brought about a total remission of
his disease.
I hung on every
word. Truly, he was speaking my language, and I could relate to his experience directly from my own.
Like him, I had chosen to do it my own way when, after one high-tech, heavily drugged
hospital delivery, and a second natural childbirth, again in the environment of
a hospital (which required me to fight off a constant barrage of unnatural
interventions), I’d decided to have my third child at home. Instead of
laughter, my magic bullet had been breathing,
which is a surefire, proven strategy for releasing endorphins and quelling pain.
Obviously, this is what previous generations of women, in
the days before IV drips and synthetic painkillers, had relied on. Both they
and their babies must have been better off for the experience, as I certainly
felt myself to be.
Even though I
questioned Cousins’s notion that endorphins are also the key to the healing
power of laughter, there was no doubt in my mind that he was on to something
wonderful. What it was hit me in a sudden flash of awakening: Here were the direct implications of all our efforts to understand the neuropeptides,
the brain chemicals of mood and behavior, to trace the chemical pathways by
which they communicated with the immune system
and every other bodily
system as well! Cousins was saying that the work I’d been doing all along
pointed to a new avenue
for healing. With this new insight, something in me woke up, leading me to see clearly what I’d barely glimpsed back when my father
was dying and I was racing to understand his condition—that receptor
science
could lead to a whole new way of understanding and treating cancer and other
diseases as well. On an intellectual level, I felt like I was shedding an old
skin, the last vestiges of old-paradigm thinking.
CONCEPTION
One unusually warm
spring afternoon, Mike and I were cruising around in my Fiat convertible
through Rock Creek Park, seeking the perfect spot to enjoy the grass, a bottle of beer, and each other. Our conversation had turned to the
research I’d done in an effort to save my father from lung cancer. The mystery
of the small-cell-bombesin connection was always in the back of my mind, and now, with Michael listening, I could
wonder out loud why in the world a cancerous
lung cell would be secreting peptides. Suddenly, Michael blurted out, “Maybe
it’s because the cancer cells are really macrophages!”
As soon as the
words were out of his mouth, I instantly had the feeling I get when I know a
wild idea is right. Now, more than ever, I was willing to trust my intuitions and design experiments around them with an enthusiasm my colleagues often dismissed as unscientific.
In fact, I had
accumulated some background knowledge about macrophages by this time, because
these white blood cells were Michael’s passion. The commonly held view was that
macrophages were designed to do very basic functions. If you get a splinter in
your finger, for instance, hordes of macrophages descend upon the invading
bacteria to gobble them up, releasing enzymes to digest the debris and then
cart it away. The lungs contain macrophages whose function it is to suck up all
the dirt—pollen, dust, carbon particles, and other chemicals—we take in with
each breath. Theoretically, if you
were to fill a normal lung with water, shake it, and turn it upside down,
billions of macrophages would flood out. It you did this with a lung from a
cigarette smoker, there would be ten times as many macrophages.
But what Michael
was considering was brilliantly radical. He was suggesting that small-cell carcinoma was not a matter of normal lung cells turned
cancerous, the traditional view, but, instead, stemmed from the macrophages
that had been drawn into the lung
to clean up the
dirty residue left by smoking.
Somehow,
the healing work of the macrophages had gone terribly awry, and the macrophages
had mutated, becoming cancerous. It was the kind of idea only someone who saw beyond the reigning
paradigm would have dared to suggest.
Although
Michael was well versed in the literature and even in the unpublished musings
of immunology, there was still room in his thinking for the word somehow.
Not being an
immunologist myself, I could afford to be equally fresh in my perspective.
Moreover, being in love, I always found Michael’s “somehows” terribly
plausible. But this was a somehow we could test, a wild proposition that would
be borne out—or not—by a simple experiment. Long chances like this were just what I’d been trained to grab
at, regardless of what the literature claimed.
We designed the
experimental approach that very afternoon in Rock Creek Park. The instant
Michael had said the word “macrophage,” I’d pounced on it
and pulled the Fiat over to the side of the road. Happily, we leapt out,
six-pack in hand, to sprawl on the grass with a pad and a pen, and started
brainstorming the science. We became so engrossed in our discussion that we
failed to notice an approaching policeman who abruptly ordered us to hand over
the beer and wrote us a ticket. To
his extreme annoyance, we barely acknowledged him, so intoxicated were we with the new idea that small-cell lung cancer might
be a case of mutated
macrophages.
LABOR
It took a year
to finish the work. Our assumption was that if these lung-cancer cells were
actually macrophages, then they ought to look and act like macrophages. They certainly had very
little in common with normal lung cells, which had been our first clue. If,
indeed, they really were macrophages, it would explain how they replicated so
quickly and traveled, or metastasized, so widely, both activities commonly associated with macrophages, and much more typical
of small-cell compared to other types of lung carcinoma. Our research strategy
involved using antibodies that typically bound to macrophages to see if they
also bound to the cancer cells. We devised a simple method of detecting
antibody- binding to receptors on the cancer cells. If the small cells had the
same surface receptors as macrophages, then they probably were macrophages.
We picked up the
cancer cells from a tissue bank facility up the road in Rockville, Maryland,
where two different small-cell tumor lines had been left on deposit by, of all
people, my old collaborator Adi Gazdar, who had grown them while he was working
in the lab of my dad’s doctor.
I thought it ironic, even
poetic
justice, that if the samples hadn’t been left there, the testing of our
hypothesis would have ground to a halt. But from this prominent researcher’s
perspective, I suppose, it was his worst nightmare: outsiders, led by the
unstoppable Pert, stealing into his field and using cell lines started in his
lab to prove an idea he hadn’t thought of. We proceeded in utmost secrecy,
partly to keep low and out of the line of fire, and partly because we didn’t
yet know whether our idea was crazy or spectacular.
Michael took off
on the project. Using a modified version of the original opiate-receptor assay,
he assayed the cancer cells to identify their receptors. He did most of the
work after hours, using an old, discarded Triple M machine he found in the
basement at the Dental Institute, and brought the data back to my house in the
evening. Even though the machine had a big crack in it, which Michael had to
continually shoot full of silicone goop to maintain the vacuum seal, the Triple M provided a quick
and dirty method for
getting our results.
We stayed up
late, poring over the data, trying to reduce the long sheets of numbers to a few facts we could be sure of. Although we kept mum
about what we were finding, not
wanting the cancer guys to get wind of our activities and accuse us of poaching
on their turf, they eventually heard rumors about the work we were doing. And
we, in turn, heard rumors that they might be doing work and coming up with data
similar to our own. But neither could communicate with the other to aid in the process,
for all the old familiar
reasons of power,
ego, and turf.
In contrast to
our lab, theirs was huge, a gigantic machine churning out data, measuring
anything and everything possible to measure on the small cells without a specific hypothesis to guide
them. We, on the other hand, were two people with a definite hypothesis: These
cancer cells were somehow related to macrophages. More focused than the cancer
researchers, we chose to scan for only those markers relevant to our theory.
DELIVERY
Eureka! It worked.
Michael’s assay
clearly demonstrated that the macrophage antibodies had bound to the cancer
cells, and we concluded that these cancerous lung cells looked and acted too
much like macrophages for this to be just a coincidence. The macrophage antibodies had bound to the cancer cells because those cells
were macrophages—or, to be more precise,
mutated macrophages. We further concluded that the cancerous cells had
originally arisen not from lung cells but from macrophages that had migrated to
the lung from the bone marrow to participate in the cleanup and repair of
damaged tissue. Somewhere on their journey between the bone marrow and the lung, they had mutated
and turned into cancers
that metastasized and spread everywhere, eventually causing death.
The startling
implication of our research, so radical it frightened even us, was that there
was a clear connection between cancer, the immune system, and toxicity
in the body. Small-cell lung cancer, it appeared, was one disease
that was entirely related to a toxic condition in the body. The “dirt”
in the lung from cigarette smoking (and presumably from other forms of
pollution as well) had caused the immune system to go into hyper-response, in
the form of sending in more and more macrophages to try to repair the damage, a situation that could
not go on forever without some kind of mutation or “mistake” occurring in the
DNA of these cells. Eventually, the mutated cells lost their ability to do the
job, and grew wildly in response
to peptide hormones
like bombesin, metastasizing all over the body,
following peptide signals. The paper describing this research, “Origin of human
small-cell lung cancer,” was accepted by the highly visible journal Science, and appeared in September of
1984—the first of many Ruff and Pert papers to come.
While we didn’t
dare to include this speculation in the paper, we wondered privately: Had we
found the underlying mechanism that explains how cancer is a response to
toxicity from environmental pollutants in the air and chemical additives in the
diet? This connection had long been suspected but little investigated by the
cancer establishment, and now we were seeing a mechanism by which it could be explained.
Preferring to
explore that particular speculation more thoroughly before committing it to
print, we used our closing paragraphs to open up an equally controversial
possibility concerning the intercommunication among three key systems of the
body. We summarized the data suggesting that the same peptides found in the
brain were also found in the immune system, and that the nervous, endocrine,
and immune systems are functionally integrated in what looks like a psychoimmunoendocrine network. This was
a key realization, which now appeared in print for the first time. We boldly postulated that
this network should be seriously considered in explaining the pathology of not
only cancer but other disease states as well—a theory
soon to become
the basis for the emerging
field of psychoneuroimmunology (now often referred to its PNI).
What we had
seen in our research was that the brain, the glands, the immune system, indeed
the entire organism, were joined together in a wonderful system coordinated by
the actions of discrete and specific messenger molecules. These findings had
prompted us to ask some interesting questions: Did the endocrine system
communicate with the immune system? Yes, Blalock had already shown this, so we
figured there was nothing too alarming in saving it again, despite the fact
that Blalock was still viewed as a virtual heretic in his field. Did the immune
system, via these peptidergic messengers, communicate with the nervous system or the brain? Yes, there were many ways
that peptides from immune cells could affect the brain through their action on
peptide receptors in the brain’s blood vessels, on surrounding membranes, or
even on neurons (brain cells) themselves! But we also had to consider a
slightlv more troubling question as a result of our research, and that
was: Did the brain communicate with the immune system?
And
did this have implications for cancer-growth spread or for antitumor immune
responses? Now, it was barely acceptable to suggest that the body influenced
the mind, but to even hint that the mind might influence the body— well, that
reeked too much of mind-over-matter, and only, wild-eyed Californians and
out-of-print Russians dared do that, at least in 1984!
But Michael and
I knew that what we were looking at was incredibly paradigm-smashing and revolutionary—the part played by the mind in the growth and development of cancer tumors.
At the time we organized our findings into a paper, we could cite only a handful of
papers that dealt with these ideas, and then only in a rudimentary and
fragmented fashion. We weren’t alone in
questioning the old static model, but no coherent synthesis was possible; indeed, much of the key data hadn’t existed until then. This was our contribution
—and
it all had to do with what we had discovered about neuropeptides, building on
work I’d been doing for ten years.
Neuropeptides,
those chemicals secreted by the brain and known to mediate mood and behavior, were clearly signaling the cancer cells via their receptors
and causing them to grow and travel, or metastasize, to different parts of the body. In the case of small-cell lung
cancer, the peptide mechanism seemed to be bombesin (rather than the
endorphins), which could pull over the cancer cells through chemotaxis, latch onto their receptors, and then program their growth and division.
In a 1985
follow-up paper, we speculated: Could excess or inappropriate production of
neuropeptides released by the immune system, or by the brain, or by any other organ system in the body, promote other forms of cancer also? Was
the
cancerous tumor really part of a network, receiving and sending information
that linked it to the brain and the immune system? (The “link” provides a
mechanism by which these body systems may regulate, control, promote, or retard the actions of one another.) In
later papers, we showed that besides the immune cells, many different kinds of
cancerous cells were also chemotaxing according to neuropeptide signals. This
process became a key to our thinking about the mind-body basis for cancer and
other diseases, especially those that were a part of the psychoimmunoendocrine
system. Because so many peptides were active, we could put forth a new precept:
Cancer cells have neuropeptide receptors. This was antidogma and therefore
profound, with rich implications that we and others were eager to explore.
COLLISION
In the euphoria
of our romance, neither of us had given much thought to how vulnerable Michael
was in all this. As a lowly postdoc, he had stuck his neck out, working with his lover on a
paper to appear in one of the most prominent journals in the scientific arena,
while at the same time jousting with a major
player whose institute had God knows what connections with Michael’s own
institute. He had been “on loan” to my lab thanks to his wonderful boss, a brilliant section chief named Sharon Wahl,
who generously lent her own energy and resources to aid our studies at the time.
If Michael humiliated his superiors or caused
a downpour of bad publicity on his branch,
he’d be scrubbing test tubes in the Dental Institute basement for the rest of his
career.
The day our
paper was accepted, and prior to its publication, Michael went alone to the
Cancer Institute to show the director our data. I certainly had no desire to
see him again; the mere memory of the cafeteria harangue over a year and a half
before was upsetting enough. I almost expected Michael to come staggering back
with a knife in his chest. Instead, he reported, the cancer researchers had
pulled out a ton of recent data showing results similar to ours. The situation
was a classic: Their work had also revealed the connection between macrophages and small-cell
cancers, but since they didn’t have a hypothesis to make any sense out of it,
they had overlooked it, and had run off chasing ten other ideas.
In my view, an
old-paradigm insistence on the separateness and autonomy of the individual
disciplines had blinded them to
the significance of their data,
preventing
them from understanding that it all added up to the fact that the nervous and
immune systems were clearly in communication with each other. Their own
interpretation was quite different. In a letter that appeared in Science shortly after our article, they
wrote: “We noticed the similarity, but we
believe it was insignificant.” The obvious implication was that since they
were the cancer specialists, they knew what they were talking about.
When the editors
of Science gave us a chance to
answer, which is how these disagreements are handled formally, we were happy
see our “wild” ideas in print once again, exactly a year after the initial
report. We had drafted the response together, seeing it as an opportunity to
reiterate our theory and discuss our conclusions further. In fact, we were elated to find that in our opponents’
remarks there was information we could turn around and use to bolster our own theory.
Our approach was
threateningly interdisciplinary in complete violation of all kinds of
traditional boundaries between scientific fields, bureaucratic departments, and
medical specialties. We were investigating the origins of cancer—even illness
itself—in an area far away from the cancer-genes-gone- awry-in-a-vacuum
mentality that was fashionable and highly funded. But for scientists at NIH to
follow up on our work, they would have to talk openly with trust, respect, and
even mutual admiration to folks from other branches and institutes, a not very
likely scenario given the ongoing interdepartmental funding competition.
In the ensuing Science debate, our opponents tried to destroy
our argument but, in the end,
only succeeded in confusing themselves. The paper was cited and mentioned for
about a year before the field moved on, essentially ignoring our points and
giving the game to the cancer lab. Years later, the field would finally return
to the role of peptides in connection with cancer and the immune system, and
Terry Moody would be lured away from his full professorship at George
Washington University to the NIH’s Cancer Institute to conduct research on the
effects of bombesin on the growth of cancer cells. Slowly, the field would come
around to accepting the possibility that if bombesin made these cells grow,
then finding an antagonist to bombesin—a receptor blocker—might provide a
useful therapeutic a magic
bullet. But over ten years would elapse
before that possibility would
be seriously investigated again.
It seems
shameful that the doorway we stood before more than a decade ago is just now being reopened, and still only
at the level of basic research, not in clinical trials where treatments are
tested for use by the public. Michael and I
later
went on to explore the possibility that if the cancer cells were indeed
macrophages, then perhaps
they would act like macrophages if given macrophage
growth hormones. Adult macrophages do not replicate, so growth hormones might cause the immature macrophages to grow up and stop dividing.
Both of these
ideas, that of blocking a growth factor like bombesin by using a receptor
antagonist, and that of providing a growth factor in the hopes of causing these
tumors to differentiate and stop dividing, are examples of the new field of
peptide pharmacology, as opposed to the old toxic treatments. One example of our newfound ability to use receptor antagonists to retard or
stop a cancer involves the peptide
LHRH (luteinizing hormone releasing hormone). Since LHRH plays a role in the development of the male prostate gland,
and seems to be necessary for continued growth of
the youthful cells that line the tube leading away from the gland
into the penis,
it’s not surprising that doctors have been
able to use LHRH antagonists successfully to treat
tumors containing receptors for LHRH.
I do not want to
give the impression that peptides are the only substances important in
understanding cancer. Other information substances that are not peptide-based, such as the sex hormones,
also play a part in the network,
acting to promote growth that may lead to cancer. One of these,
estrogen, has been shown
experimentally to increase the growth of certain breast tumors. And, once
again, the use of an antagonist to block the receptors has shown great promise as a cancer treatment. The antagonist, a
drug known as tamoxifen, has been extraordinarily successful in treating
women who have estrogen-dependent
breast cancers. (Since not all breast cancers are estrogen-dependent, a sample
of the tumor can be readily tested to determine whether or not it contains
estrogen receptors before treatment is begun.)
The Cancer
Institute appears to be slowly shifting gears, but old paradigms die hard, and the resistance to new ideas
continues to delay progress, so that the promise of ideas we had proposed
so many years ago still remains unfulfilled.
PNI
While our paper
had relatively little impact on the cancer establishment at the time, it did
make an impression on certain other researchers who were moving, mostly
silently, behind the scenes to establish the new field of
psychoneuroimmunology, or PNI. By providing PNI with a clear scientific
language, that of neuropeptides and their receptors, we helped legitimize
it.
It’s quite
amazing that PNI was able to arrive
on the scene relatively
unscathed, given the climate of scientific conservatism that generally ensures that newcomers will be vigorously
and sometimes brutally hazed before being admitted to the club. The first time
cellular and molecular PNI was seriously presented in a public forum was in
1984, when I was invited to a conference in Rome that went by the name “Endorphins and Opiate Receptors in the Periphery.”
There I assembled a panel of speakers, including doctors Michael Ruff, Ed Blalock, and several others, to
speak specifically to our finding of a psychoimmunoendocrine system,
the term Michael
and I had used in our paper for the linkup of the three systems. For my talk,
I’d prepared a slide that showed
a triangle to graphically represent the three systems that used peptides to
communicate with one another. It was a pleasant and synchronous surprise to see
that two other presenters had created the exact same slide, which meant that we’d all arrived at the same
understanding more or less simultaneously. Shortly after that, Herb Spector, an
NIH psychologist, organized a private, but higher profile, event at the Palace, one that had three Nobel
laureates in the audience,
and put PNI more solidly
on the map, a separate
field with its own secure funding niche.
In the
beginning, several names for the new science were proposed. One of these was
“psychoimmunology,” originally coined by psychiatrist George Solomon back in the fifties. This
granddaddy term grew from Solomon’s observations on how profoundly personality
affects disease. A competing name was proposed by Herb Spector,
who was one of the few Americans who bothered to keep track of what the Russian behaviorists,
the heirs of Pavlov, had been up to. He knew they were light-years ahead of us
in understanding the holistic balance
of the body, and had been proving that the immune system could be shown to
respond to classical conditioning for decades, thus implicating the nervous
system as part of the process by which the body maintains health or lapses into a disease
state. Spector’s proposed term was “neuroimmunomodulation.”
The term that
triumphed, psychoneuroimmunology, was championed by Dr. Robert Ader, an
experimental psychologist who had coined the word for both a conference and a
book that appeared under that title in 1981. Inspired by the Russians, Ader had
done some interesting experiments with rats that showed the immune system could
be conditioned, and therefore did not operate
autonomously, as immunologists had always believed, but was under the influence
of the brain. Within the field, Ader had taken up a rather right-wing
banner,
fighting hard against what he considered a left-wing drift into
pseudoscientific thinking, the kind of thing that he thought Californians were
expressing by including PNI in their “New Age” modalities. His PNI was scientifically solid, he insisted, grounded in
meticulously designed rat experiments, and in the resolutely unflaky tenets of
behavioralism.
Psychoneuroimmunology: I personally find
it a misnomer, a term that is not only inaccurate, because
it reveals only part of the picture,
but also redundant. Of course, it’s necessary to
concede that I speak as an also-ran in the naming game. The term Michael
and I proposed, “psychoimmunoendocrinology,” made a
point of including the endocrine system,
to make it clear that we were looking
at a network hookup of multisystems, not just the brain and the immune system.
To us, psycho meant the same thing as
neuro, and did not need double
emphasis, as if psycho weren’t really
good enough and needed neuro to make
it legitimate. However, our proposal was met with a deafening silence and has
since gone the way of the dinosaur.
A BODYWIDE SYSTEM
In the early days of our professional relationship, Michael had asked me what I meant by the term neuropeptide. Why add the prefix neuro, he argued, if the same peptide
is found in the gut and immune
system, as well as in the brain?
And
why call it a neuroreceptor if it is
also found in the gut, in the immune system, alongside the spinal cord, and who
knows where else? By tossing out these
linguistic distinctions and simply using the term peptides or information
substances to refer to all peptides regardless of where they occurred, it
became more obvious that we were describing a bodywide communication system,
one we suspected was ancient in origin, representing the organism’s first try at sharing information across cellular
barriers. The brain, or neuro,
component was only one part of the organism’s nonhierarchical system to gather,
process, and share information (albeit the most complicated and sophisticated
component by far).
But what was
this bodywide system? How did it translate into our experience, our behavior
as human beings?
These were some of the questions we were
asking. I knew from my brain mapping over the years that the communicating
chemicals were most dense in certain areas of the brain and along the sensory
pathways. We also knew how the mind drugs heroin,
opium, PCP, lithium,
and
Valium
entered the network and worked on the receptors, and how the endogenous, or “in-house,” substance,
endorphin, communicated over a wide range. If we were to characterize exactly
what these chemicals were doing, we would have to say they affect the emotional
state of the person who takes them, making him
or her happy, sad, anxious,
or relaxed, or something somewhere along the continuum of these
emotions. And when we focus on emotions, it suddenly becomes very interesting
that the parts of the brain where peptides and receptors are richest are also the parts of the brain that have been implicated in the expression of emotion. I don’t remember
whether it was Michael or I who said
the words first,
but both of us had the gut feeling that we were right:
“Maybe these peptides and their receptors are the biochemical basis of
emotion.” Finally, we were looking at the implications of the fact that the limbic system had the densest concentration of
these receptors.
Could it be that what we were seeing were the molecules of emotion?
Unfortunately, emotion is another of those words
mainstream science likes to spit out at the very first taste. I was enormously
bolstered when UCSF psychologist Paul Ekman taught me that Charles Darwin had
been a theoretician of emotions
as well as of the origins of species. Still, I was nervous the first time I stood up in front of my peers and
suggested that this bodywide network of peptides and receptors might be the molecular basis of emotion.
I’d hoped that, as strict materialists, they might
find some satisfaction in hearing that emotions could now be understood as a
basic, molecular, biological process. But, no, too many borders had been
crossed, too many taboo words spoken. People did what they do to ideas that
won’t fit the reigning paradigm—ignore them. The pop journals, however,
picked up the theory several
years later with no attribution.
We
published the key paper on our theory in the Journal of Immunology in 1985. To quote from the abstract:
A major
conceptual shift in neuroscience has been wrought by the realization that brain
function is modulated by numerous chemicals in addition to classical
neurotransmitters. Many of these
informational substances are neuropeptides, originally studied in other
contexts as hormones, gut peptides, or growth factors. Their number presently
exceeds 50, and most, if not all, alter behavior and mood states,
although only endogenous analogs of psychoactive drugs like morphine, Valium, and
phencyclidine
have been
well appreciated in this context. We now realize that their signal specificity
resides in receptors rather than the close juxtaposition occurring at classical
synapses. Precise brain distribution patterns for many neuropeptide receptors
have been determined. A number of brain loci, many within emotion- mediating
brain areas, are enriched with many types of neuropeptide receptors, suggesting a convergence of information
processing at these nodes. Additionally, neuropeptide receptors occur on mobile
cells of the immune system: monocytes can chemotax to numerous neuropeptides
via processes shown by structure-activity analysis to be mediated by distinct
receptors indistinguishable from those found in the brain. Neuropeptides and their receptors thus join the brain, glands, and
immune system in a network of communication between brain and body, probably
representing the biochemical substrate of emotion.
The molecules of
emotion. This was our new paradigm, newborn and a bit shaky about its place in
the universe, but lusty in its cries for attention, its insistence on life.
Meanwhile Michael and I would be rocked by the death throes of the old paradigm
in one of our next adventures—the race to develop a treatment for AIDS.
9 THE PSYCHOSOMATIC NETWORK: A CONCLUDING LECTURE
IT IS
USUALLY at this point in my
lecture, when I’ve leaned hard on the science and still have more to present,
that I try to lighten things up a bit and throw in a slide that will amuse
my audience. One slide that suits this purpose well is that of a brightly colored MRI scan of
the human brain, a visual delight, almost as beautiful as the rainbow butterfly
pattern Miles and I saw when we first began to autoradiograph animal brain
slices. But this isn’t just any brain, I tell my audience, looking forward to the reaction
I’ll get when I announce that the brain they are looking at is my very own. And
then I proceed to explain how one day we’ll be able to tell from the variety and density of receptors in certain areas what kind of life I have led, which
substances I have abused, and, in general, what the biochemicals of emotion
are doing in my brain.
After that bit of
fun, I move on to a
slide that introduces the subject of the next
segment of my lecture. It reproduces an editorial that appeared in Nature magazine commenting on Ed
Blalock’s shocking discovery in 1982 that our immune system cells are secreting
peptides, most notably endorphins. The idea that there were brain peptides in
the immune system was so unsettling to immunologists that Blalock’s work was
not believed at first—a virtual replay of the disbelief that had greeted
Jesse Roth’s work showing insulin
in the brain.
The
establishment was still committed to the separation of body and brain. But,
finally, Nature had printed
this editorial in which it grudgingly acknowledged the validity of Blalock’s
research, while disputing
its implications. Nature
warned the scientific community to beware of those “radical
psychoimmunologists” who would dare to use Blalock’s work to propose that body
and mind were in communication with each other, in fact that the body mirrored
the mind. Which is exactly the path I chose to pursue in my subsequent research
at the NIH. As I’ve mentioned elsewhere, my colleagues and I loved calling
ourselves the radical psychoimmunologists.
THE IMMUNE CONNECTION
We have seen how
the neuropeptides and their receptors, the biochemicals of emotion, act to
orchestrate many key bodily processes, linking behavior and biology to effect a
smooth functioning of the organism. At this point, taking my lead from Ed
Blalock’s work, I would like to introduce a new layer to this dynamic, the role
played by the immune system, which forms a vital link in the overall hookup of
the biochemistry of emotions.
I have talked
about how the endocrine system, which historically had always been studied as
completely separate from the brain, conceptually resembles the nervous system.
The brain is a big hormone bag! Pockets of peptide juices are released from
both glands and brain cells, after which they bind with specific receptors that
enable them to act at sites far from where the juices originated. (This is what
endocrinologists call “action at a distance.” Looked at in this way,
endocrinology and neuroscience are really exploring two aspects of the same process.)
Now I want to
show you how the immune system is part of the same network as the endocrine and
nervous systems, even though most immunologists still consider it a separate
and autonomous field of study.
The immune system
is made up of the spleen, the bone marrow, the lymph nodes, and various kinds
of white blood cells, some of which circulate
throughout the body, while others reside in the various tissues of the body,
including the skin. Its overall purpose is to defend against pathological
invaders that threaten the health of the organism and to repair any damage they
cause. To do this, the immune system must define the boundaries of the
organism, distinguishing between what is self and what is not self, that is, determining what is part of the organism
and needs to be repaired and restored versus what is part of a tumor and needs
to be killed.
A key property of the immune system is that its cells move. Unlike brain cells, which, for the most part, do
not move, the cells of the immune system do their job by traveling throughout
the organism to wherever they are needed to mount a defense or repair damage.
Certain white blood cells known as
monocytes (called macrophages in later stages of growth),
for example, whose function is to ingest foreign organisms in the bloodstream,
start life in your bone marrow and then diffuse out to travel through your
veins and arteries, deciding where to go by following chemical cues. Monocytes
and other white blood cells, such as lymphocytes,
travel along in the blood and at some point come within “scenting” distance of
a given neuropeptide, and because these cells have receptors for that particular neuropeptide on their surface,
they begin literally to
chemotax, or crawl toward it. This
action is very well documented, and there are excellent ways of studying it in
the laboratory.
Now,monocytes
are responsible not just for recognizing and digesting foreign bodies, but also for wound healing
and tissue-repair mechanism. For example, we have
enzymes that produce and degrade collagen, an important structural material out
of which the body’s very fabric is made. What we are talking about, then, are
cells with vital health-sustaining and healing functions.
When Michael
Ruff and I read Ed Blalock’s astonishing paper on brain peptides in the immune system,
we went looking for neuropeptide receptors there. And the radical discovery we made was that every nenropeptide receptor we could find in the brain is
also on the surface of the human monocyte. Human monocytes have receptors for opiates, PCP, and other peptides such as
bombesin. These emotion-affecting peptides, then, actually appear to control
the routing and migration
of monocytes, which are very
pivotal to the overall health
of the organism. They communicate with the other lymphocytes, called B cells and T cells, by
interacting through peptides called cytokines, lymphokines, chemokines, and
interleukins and their receptors, thus enabling the immune system to launch a
well-coordinated attack against disease. The action looks something like this:
A health-sustaining cell like the monocyte circulates through the blood until
it is pulled over by the chemical attraction of a peptide—for example, an
endorphin, the body’s endogenous opiate. It can then connect with that opiate because it has the receptor to
do so.
But immune
cells don’t just have receptors on their surfaces for the various
neuropeptides. As demonstrated by the paradigm-shaking research of Ed Blalock at the University of Texas in the early
eighties—and confirmed by research done by Michael Ruff, Sharon and Larry Wahl,
and me—immune cells also make, store, and secrete the neuropeptides themselves. In other words,
the immune cells are making
the same chemicals that we conceive of as controlling mood in the brain. So, immune cells not only
control the tissue integrity of the body, but they also manufacture information
chemicals that can regulate mood or emotion. This is yet another instance of
the two-way communication between brain and body.
Or that’s how we
see it. But such an idea is so astounding to both neuroscientists and
immunologists that many will still maintain, as the Nature editorial did, that just because these communication
molecules are there doesn’t mean they’re actually used to communicate. After
all, their education was based on the idea of an impenetrable “blood-brain barrier,” the existence
of which had
been
“proved” by turn-of-the-century experiments in which huge dye molecules
injected into the body could not get into the brain. And, certainly, it is true
that many drugs are absorbed slowly,
if at all, into the brain. But very recent evidence shows many ways that
cytokines, chemokines, lymphokines, interleukins, and other immunopeptides can
breach the barrier. One well- documented route of access involves their binding
with receptors on the surface of the
brain in such a way as to affect the permeability of the brain’s surface
membranes. From there they can propagate a signal that gets picked up by other
peptides and receptors deep within the brain. In fact, they probably do this routinely.
The question
remains: What is the purpose of such communications? To answer, let’s look at an example of a neuropepride that has
receptors in several different bodily systems—not just the brain and the immune
system but the gastrointestinal system as well. Consider CCK, a neuropeptide
governing hunger and satiety, which
was first discovered and then sequenced by chemists who were
exploring its action on the gut. As discussed earlier,
if you were given doses of CCK, you would not want to eat, regardless of how long it had been
since your last meal. Only recently have we been able to show that both the
brain and the spleen—which can be described as the brain of the immune system— also contain receptors for CCK. So
brain, gut, and immune system are all being integrated by the action of the
CCK. Why would this be so?
There are nerves
that contain CCK all along the digestive tract and in and around the
gallbladder. After a meal, when the fat content is moving through the digestive
system to your gallbladder, you experience a feeling of satisfaction, or
satiety—thanks to the signal CCK sends to your brain. CCK also signals your
gallbladder to go to work on the fat in the meal, which enhances the feeling of
fullness. This much we know. As to what the CCK receptors
are doing on cells
in your immune system at this point, I can only conjecture. It certainly would
not be a good idea to have your immune system revved up shortly after eating,
when the food is still undigested, because you don’t want your immune system mounting an attack response on the
undigested meal! For this reason, it would make sense if the same CCK system
that creates a sense of satiety in your brain
and makes your gallbladder go to work would also be able to signal the
immune system to slow down.
NETWORK
Let me summarize
the basic idea I have been developing. The three
classically separated areas of neuroscience, endocrinology, and
immunology, with their various
organs—the brain; the glands; and the spleen, bone marrow, and lymph
nodes—are actually joined
to each other in a multidirectional
network of communication, linked by information carriers known as
neuropeptides. There are many well-studied physiological substrates showing that communication exists in both
directions for every single one of these areas and their organs. Some of the
research is old, some of it is new. For example, we’ve known for over a century
that the pituitary gland spews out peptides throughout the body. But it’s only
been a few years that we’ve known that peptide-producing cells like those in
the brain also inhabit the bone marrow, the place where immune cells are
“born.”
The word I want
to emphasize in regard to this integrated system is network, which comes from the relatively new field of information
theory. In a network, there is a constant exchange and processing and storage
of information, which is exactly what happens, as we have seen, as
neuropeptides and their receptors bind across systems. The informational nature
of these biochemicals led Francis Schmitt
of MIT to introduce, in 1984, the term information
substances, a wonderfully descriptive way of referring to all of the
messenger molecules and their receptors as they go about their job of linking brain,
body, and behavior.
Schmitt did us a great favor by giving
us a metaphor to explain
the purpose of the complex overlapping of these
multiple-functioning substances as they move from one system to another, one
job to another. He included in his new generic category both long-familiar substances such as the classical neurotransmitters and the steroid
hormones, and newly discovered ones such as peptide hormones, neuropeptides, and growth factors—all ligands that trigger
receptors and initiate a cascade of cellular processes
and changes.
So what we have been talking
about all along is information. In thinking about these
matters, then, it might make more sense to emphasize the perspective of psychology rather than of neuroscience, for the term psycho clearly
conveys the study of mind, which
encompasses but also goes beyond
the study of the
brain. I like to speculate that what the mind is is the flow of information as
it moves among the cells, organs, and
systems of the body. And since one of the qualities of information flow is that
it can be unconscious, occurring below the level of awareness, we see it in operation
at the autonomic, or involuntary, level of our physiology. The mind as we experience it is
immaterial, yet it has a
physical substrate, which
is both the body and the brain.
It may also be said to
have
a nonmaterial, nonphysical substrate that has to do with the flow of that
information. The mind, then, is that which holds the network together, often acting below our consciousness, linking and coordinating
the major systems and their organs and cells in an intelligently orchestrated
symphony of life. Thus, we might refer to the whole system as a psychosomatic
information network, linking psyche,
which comprises all that is of an ostensibly nonmaterial nature, such as mind, emotion,
and soul, to soma,
which is the material world of molecules, cells, and organs. Mind and
body, psyche and soma.
This view of the
organism as an information network
departs radically from the
old Newtonian, mechanistic view. In the old paradigm, we saw the body in terms
of energy and matter. Hardwired reflexes, caused by electrical stimulation
across the synapse, ran the body in a more or less mechanical, reactive
fashion, with little room for flexibility, change, or intelligence. With information added to
the process, we see that there is an intelligence running things. It’s not a matter of energy acting on matter to
create behavior, but of intelligence in the form
of information running all the systems and creating behavior. Walter B. Cannon, William
James’s debater, was onto this when he referred to the
“wisdom of the body,” and today certain manipulative healers such as
chiropractors refer to it as the body’s “innate intelligence.” But,
classically, there is no such thing
as an intelligent organism, and to say so is heresy to the old guard who cling to a concept of the
body as unintelligent, a bundle of mass and matter stimulated by electrical
impulses in a predictable way. Theirs is the
ultimate godless, mechanical universe, peopled by clocklike organisms,
as conceived by Cartesian and Newtonian models.
While much of the
activity of the body, according to the new information model, does take place
at the autonomic, unconscious level, what makes this model so different is that it can explain how it is also
possible for our conscious mind to enter the network and play a deliberate part.
Let’s look, for example, at the role of opiate receptors and
endorphins in modulating pain. Pain researchers all agree that the area called
the periaqueductal gray, located around the
aqueduct between the third and fourth ventricles of the midbrain, is filled
with opiate receptors, making it a control area for pain. It is also loaded
with receptors for virtually all the neuropeptides that have been studied.)
Now, we’ve all heard of the yogis
of the East and practitioners of certain mystical disciplines who have been
able, through breath training, to alter their perceptions of physical pain.
(Other people, known as mothers, demonstrate mastery equal to that of the yogis, when, with proper training such as Lamaze,
they
use breathing techniques to control pain in childbirth.) What seems to be going
on here is that these people are able to plug into their PAG (their
periaqueductal gray), gaining access to it with their conscious intention, and
then, I believe, are able to reset their pain thresholds. Reframed by conscious
expectations and beliefs, the pain is abolished, reinterpreted as either a
neutral experience or even pleasure. The question is: How can the mind mediate
and modulate an experience of pain? What role does consciousness play in such matters?
To answer,
I must return to the idea of a network. A network
is different from a
hierarchical structure that has a ruling “station” at the top and a descending series of positions that play increasingly
subsidiary roles. In a network, theoretically, you can enter at any nodal point
and quickly get to any other point; all locations are equal as far as the
potential to “rule” or direct the flow of information. Let’s see how a concept
like this explains the process by which a conscious intention can reach the PAG
and use it to control pain.
Conscious breathing, the technique employed
by both the yogi and the
woman in labor, is extremely powerful. There is a wealth of data showing that
changes in the rate and depth of breathing produce changes in the quantity and kind
of peptides that are released from the brain stem. And vice versa! By bringing this process into consciousness
and doing something to alter it—either holding your breath or breathing extra
fast—you cause the peptides to diffuse rapidly throughout the cerebrospinal
fluid, in an attempt to restore homeostasis, the body’s feedback mechanism
for restoring and maintaining balance.
And since many of these
peptides are endorphins, the body’s
natural opiates, as well as other kinds of pain-relieving
substances, you soon achieve a diminution of
your pain. So it’s no wonder that so many modalities, both ancient and New
Age, have discovered the power of controlled breathing. The peptide-respiratory
link is well documented: Virtually
any peptide found anywhere else can be found in the respiratory center. This
peptide substrate may provide the scientific rationale for the powerful healing
effects of consciously controlled breath patterns.
We are all aware
of the bias built into the Western idea that the mind is totally in the head, a function
of the brain. But your body is not there just to carry
around your head. I believe
the research findings
I have described indicate that we need to start thinking about how
the mind manifests itself in various parts of
the body and, beyond that,
how we can bring that process into consciousness.
MIND IN BODY
The concept
of a network, stressing the interconnectedness of all systems
of the organism, has a variety of paradigm-breaking implications. In the
popular lexicon, these kinds of connections between body and brain have long
been referred to as “the power of the mind over the body.” But in light of my
research, that phrase does not describe accurately what is happening. Mind
doesn’t dominate
body, it becomes body—body and mind are
one. I see the process of communication we have demonstrated, the flow of
information throughout the whole organism, as evidence that the body is the actual outward
manifestation, in physical space, of the mind. Bodymind, a term first proposed by Dianne Connelly, reflects the
understanding, derived from Chinese medicine, that the body is inseparable from the mind. And when we explore the role
that emotions play in the body, as expressed through
the neuropeptide molecules, it will become clear how emotions can be seen as a key to the understanding of disease.
We know that
the immune system, like the central nervous system, has memory and the capacity to learn. Thus, it could be said that
intelligence is located not only in
the brain but in cells that are distributed throughout the body, and that the
traditional separation of mental processes, including emotions, from the body
is no longer valid.
If the mind is
defined by brain-cell communication, as it has been in contemporary science,
then this model of the mind can now be seen as extending naturally to the
entire body. Since neuropeptides and their receptors are in the body as well, we may conclude that the mind is in the body, in the same sense
that the mind is in the brain, with all that that implies.
To see what this means in practice, let’s return for a moment
to the example of the gut. The entire lining of the intestines, from
the esophagus through the large
intestine, and including each of the seven sphincters, is lined with cells—
nerve cells and other kinds of cells—that contain neuropeptides and receptors.
It seems entirely possible to me that the density of receptors in the
intestines may be why we feel our emotions in that part of the anatomy, often
referring to them as “gut feelings.”
Studies have shown that excitement and anger increase gut motility, while
contentment decreases it. And then, because this is a two-way network, it’s
also the case that the movement of the gut as it digests food and excretes
impurities can alter your emotional state. “Dyspeptic” means grouchy and irritable, but originally it referred to having poor
digestion. Or let’s look
again at the autonomic nervous system, which runs all the unconscious aspects of your body, such as breathing, digestion, and elimination. You would think that if any part of the body
functioned independently of the mind, it would most surely be the autonomic
nervous system. There, the ability to make your heart beat, your intestines digest, and your cells replicate
is carried on below
conscious awareness. And yet, surprisingly, as we discussed in the example of
yogis and women in labor, consciousness can
intervene at this level. This is the radical lesson of biofeedback, which many doctors
now teach their patients so that they can control pain, heart rate,
blood circulation, tension and relaxation, etc.—all processes previously
thought to be unconscious. Up until the early
sixties, we thought that the autonomic nervous system was run by two
neurotransmitters, acetylcholine and norepinephrine. But it turns out that in
addition to the classical neurotransmitters, all of the known peptides, the
information molecules, can be found abundantly in the autonomic nervous system, distributed in subtly different intricate
patterns all the way down both sides
of your spine. It is these peptides and their receptors that make the dialogue
between conscious and unconscious processes possible.
IN SUMMARY,
the point I am making is that your brain is extremely well integrated with the
rest of your body at a molecular level, so much so that the term mobile brain is an apt description of
the psychosomatic network through which intelligent information travels from
one system to another. Every one of the zones, or systems, of the network—the
neural, the hormonal, the gastrointestinal, and the immune—is set up to
communicate with one another, via
peptides and messenger-specific peptide receptors. Every second, a massive
information exchange is occurring in your body. Imagine each of these messenger systems possessing a specific
tone, humming a signature tune, rising and falling, waxing
and waning, binding
and unbinding, and if
we could hear this body music with
our ears, then the sum of these sounds would be the music that we call the
emotions.
Emotions. The
neuropeptides and receptors, the biochemicals of emotion, are, as I have said,
the messengers carrying information to link the major systems of the body into one unit that we can call
the bodymind. We can no longer think of the emotions as having less validity than physical, material
substance, but instead must
see them as cellular signals that are involved in the process of translating
information into physical reality, literally transforming mind into matter. Emotions
are at the nexus between
matter and mind,
going back and forth between the two and influencing
both.
HEALTH AND EMOTIONS
What, then, is
the relationship of mind and emotions to an individual’s state of health?
As we have seen, the neuropeptides and their receptors are the substrates of the emotions, and they are in constant
communication with the immune system, the mechanism through
which health and disease are created. One of the ways
we now know the immune system affects our health is through plague formation in the arteries. Immune cells squirt out
peptides that either increase or decrease the buildup
of plaque in coronary blood
vessels—a key factor
in heart attacks.
And
although we don’t know what the role of the emotions is in all this,
epidemiological evidence suggests there is a link. It’s well documented, for
example, that people have more heart attacks on Monday mornings (when the work
week begins) than any other day of the week, and that death rates peak during
the days after Christmas for Christians and after Chinese New Year for the Chinese. Since these are all days with
high emotional valence, one way or another, it seems clear that the emotions in
some way correlate with the state of people’s hearts.
Another possible
immune system connection has to do with viruses. Viruses use the same receptors as neuropeptides to enter into a cell,
and depending on how much of the natural peptide for a
particular receptor is around and available to
bind, the virus that fits that receptor will have an easier or harder time
getting into the cell. Because the molecules of emotion are involved in the
process of a virus entering the cell, it seems logical to assume that the state
of our emotions will affect whether
or not we succumb to viral infection. This might explain why one person will
get sicker from the same loading dose of a virus than another person. I don’t
know about you, but I never never get sick when I’m about to go skiing! Could
an elevated mood, one of happy expectation and hope for an exciting possibility or adventure, protect
against certain viruses? One possible explanation for how this might work is
that the rheovirus, shown to be a cause of the viral cold, uses the receptor
for norepinephrine—an informational substance thought to flow in happy states
of mind, according to the main psychopharmacological theories—to enter the
cell. Presumably what happens is that when you’re happy, the rheovirus can’t
enter the cell because the norepinephrine blocks all the potential virus
receptors.
Over the
centuries, much attention has been paid to the influence of the mental and emotional
processes on health and disease.
Aristotle was among the
first
to suggest the connection between mood and health: “Soul and body, I suggest,
react sympathetically upon each other,” he is credited with saving. But it is only since the
early twentieth century that researchers have had tools powerful enough to
discern the links and to demonstrate that one of those links, the immune
system, was trainable. In the 1920s and 1930s, pioneering Russian scientists
showed that classical Pavlovian conditioning could both suppress and enhance
the immune response. Working with guinea pigs and rabbits, for example, they
paired cues such as a trumpet blast with injections of bacteria to stimulate
the immune system. After repeated trials, the animals “learned” to activate
their immune systems without the stimulus of the bacteria injections whenever
they heard the sound of the horn.
An American
picked up this thread and did more research on the communication links between
brain and immune system. Psychologist Robert Ader of the University of
Rochester School of Medicine (who was later to coin the term psychoneuroimmunology) and his colleague
Nicholas Cohen did a
series of groundbreaking experiments in the 1970s. They trained lab rats to
associate certain stimuli with an event, much as Pavlov trained his dogs to
associate the sound of a bell ringing with the approach of food. In Ader and
Cohen’s studies, rats were given an immune-suppressing drug flavored with sweet-tasting saccharin. Eventually, they
became so conditioned to the effects of this drug that the saccharin taste
alone, divorced from the drug, caused a suppression of their immune
system—another demonstration of mental cues altering physiology.
While these
studies showed that the immune system
could be conditioned at the
subconscious, or autonomic, level, it remained for Howard Hall to show us in
1990 that the immune system could also be consciously controlled. In the
pivotal experiments Hall conducted at Case Western Reserve University in Ohio,
he instructed his human subjects in cyberphysiologic strategies. The word cyber derives from the Greek
“kybernetes,” meaning “that which steers” or “the helmsman,” and in this context refers specifically to self-regulatory practices such as relaxation and guided
imagery, self-hypnosis, biofeedback training, and autogenic training. Using
several control groups, Hall showed that those with cyberphysiologic
preparation could use these techniques to consciously increase the stickiness
of their white blood cells, as measured by saliva and blood tests.
Up
until his work, there were anecdotal reports of an association between
hypnotherapy and clinical improvements in warts and asthma, both of which may be mediated by immune changes
under subconscious control.
But there
were no measurements of change at the cellular
level, and no work
demonstrating the potential for conscious control. Hall was the first to show
that psychological factors, that is, conscious
intervention, could directly
affect cellular function in the immune system.
If the immune
system can be altered by conscious intervention, what does this mean for the
treatment of major diseases such as cancer? The idea that emotions are linked
to cancer has been around for a while. In the 1940s, Wilhelm Reich proposed the
then heretical idea that cancer is a result of the failure to express emotions, especially sexual emotions. Reich was not only ridiculed
by the medical and scientific
establishment, he was actually persecuted. It was perhaps the only time in history that the
government of the United States held an official book burning, calling for all available
copies of Reich’s
life’s work to be
rounded up by the FDA and incinerated. However, the heretical idea did not die
in that bonfire. The German psychoanalyst Claus Bahnson, among others,
continued this line of work in the interim until, today, it links up with much
of contemporary biology. More recent, 1980s, studies by Lydia Temoshok, a
psychologist then at UCSF, showed that cancer patients who kept emotions such as anger under the surface, remaining
ignorant of their existence, had slower recovery rates than those who were more
expressive. Another trait common to these patients was self-denial, stemming
from an unawareness of their own basic emotional needs. The immune
systems were stronger
and tumors smaller
for those in touch with their emotions.
Can suppressed anger or other “negative” emotions cause cancer? In addition
to the recent studies by various researchers like David Spiegel of
Stanford who have convincingly shown that being able to express emotions
like anger and grief can improve survival rates in
cancer patients, we now have a theoretical model to explain why this might be
so. Since emotional expression is always tied
to a specific flow of peptides in the body, the chronic suppression of
emotions results in a massive disturbance of the psychosomatic network. Many psychologists have interpreted depression
as suppressed anger; Freud, tellingly, described depression as anger redirected against oneself. Now we
know something about what this looks
like at a cellular level.
Take cancer, for
example. It’s a fact that every one of us has a number of tiny cancerous tumors
growing in our bodies at every moment. The part of the immune system that is responsible for the destruction of these errant
cells consists of natural
killer cells whose job it is to attack these tumors, destroy them, and rid the body of any cancerous
growth. In most of us, most of the time,
these
cells do their job well—a job coordinated by various brain and body peptides
and their receptors—and these tiny tumors never grow large enough to cause us
to become ill. But what happens if the flow of peptides is disrupted? Is it possible we could learn to consciously intervene to make sure our natural
killer cells keep doing their job? Could being in touch with our emotions facilitate the flow of the peptides that
direct these killer cells at any given moment? Is emotional health important to
physical health? And, if so, what is emotional health? These are the sort of
questions we have to start addressing if we take the links between body and
mind seriously.
Let me begin to
answer by saying that I believe all emotions
are healthy, because emotions are what unite
the mind and the body. Anger, tear, and
sadness, the so-called negative emotions, are as healthy as peace, courage, and joy. To repress these
emotions and not let them flow freely is to set up a dis- integrity in the
system, causing it to act at cross-purposes rather than as a unified whole. The
stress this creates, which takes the form of blockages and insufficient flow of
peptide signals to maintain function at the cellular level, is what sets up the weakened
conditions that can lead to disease. All honest emotions
are positive emotions.
Health is not just a matter
of thinking “happy
thoughts.” Sometimes the biggest impetus to healing
can come from jump-starting the immune system with a burst of long-suppressed anger.
How and where it’s expressed
is up to you—in a room by
yourself, in a group therapy situation where the group dynamic can often facilitate the expression of
long-buried feelings, or in a spontaneous exchange
with a family member or friend. The key is to express it and then let it go, so
that it doesn’t fester, or build, or escalate out of control.
THE UNITY OF LIFE
I’d like to
conclude my lecture for today with my final slide, that of a single- celled animal,
the tetrahymena. This is a critter so widely studied
in basic science laboratories
that it has earned the title of the “workhorse of biology.” What is truly amazing
is that this primitive unicellular animal makes many of the same peptides,
including insulin and the endorphins, that we humans do. On its single-cell surface,
Blanche O’Neil found opiate receptors
just like the ones in our brains. These same basic building
blocks, then, are found in the earliest and simplest forms of life as well as
in the most complex ones. And just as there are four basic molecules that code for all DNA in living
organisms, there is some
given
number, not yet finally determined, of informational molecules that code for
communication, for the information exchange that runs all systems in all living
things, whether that communication is inter-or intra-cellular, organ to organ,
brain to body, or individual to individual.
I like to bring
the tetrahymena to your attention because it both illustrates an important
biological fact and gives me a chance to end my lecture on a philosophical note
(after which I’ll go on to discuss some of the more practical implications of these ideas—i.e., how you can bring more consciousness into your life and use it for achieving
better physical and emotional health). Think about what it means that the same
basic informational network found in the tetrahymena is still to be found in
us. If these peptides and their receptors—the molecules of emotion—have not
only been conserved since their origins in the earliest and simplest forms of
life but have continued to grow into the incredibly elaborate psychosomatic network we have discovered in the human body, we have to conclude that their role in
evolution has been a powerful and critical one. To me, this is a stunning
demonstration of the unity of all life. We humans share
a common heritage, the molecules of emotion, with the most modest of
microscopic creatures, a one-celled being,
even though evolution has caused us to develop into trillion-celled
creatures of astonishing magnificence.
I leave you with
that thought, and thank you for your attendance here at my lecture today.
THE
HOUSELIGHTS come up as the
image on my slide screen fades, and I am once again aware of the real, live
people who have been sitting out in the audience, the ears and eyes and hearts
and minds my talk has been directed to— the trillion-celled creatures
themselves.
It was December 1987 in Puerto Rico. The piña coladas
were flowing as we American neuropsychopharmacologist greeted
one another at our annual conference. Fellow NIMHer Peter Bridge and I
spotted each other across the packed floor.
Normally reserved, even sardonic, Peter seemed really excited as he began to brief me on the first two
Americans to receive the experimental AIDS drug Michael and I had just
invented.
“Did anything
… happen?” I asked, knowing
already from the
way my heart was pounding that something had.
“Two of them—both
of them—had terrible
neuropathy, one could barely walk. The other couldn’t.”
“And now?”
“They’re both walking
normally. Their neuropathies went away. I’ve talked
to three neurologists who’ve seen a lot of AIDS patients. They said it never
happens.”
“What do you mean, ‘it never happens’?”
“When their neuropathy’s as bad as these guys’ were,
they don’t usually ever get any better.
These guys got better a few days after
starting your drug.” Peter shrugged while we hugged, both of us thrilled but
trying to stay skeptical, or at least unemotional.
Just then, the crush of neuropsychopharmacologists
suddenly moved to the window to see the rainbow that had appeared
along the horizon where the black storm clouds of the Caribbean rainy
season were starting to move off at last. It was a huge double rainbow that
lasted almost an hour, practically filling the small slice of blue sky. Later,
I watched it from my balcony with my sister Wynne, marveling at how a rainbow
at one end of the horizon could share the sky with lightning bolts tearing
through the blackness at the other end.
10 CHILD OF THE NEW PARADIGM
PROMISE
It was in Maui,
the navel of the earth, in 1985, that the promise of our theory about mind-body
cellular communication as the foundation for understanding health and disease
was most spectacularly revealed.
That year my lab was as large as it had ever been. I had a team in place, twelve people under my immediate
direction and a larger group within my circle of influence, all supporting the
work I was doing in an informal, collaborative association. Joining my people
in brain biochemistry were Michael, courtesy of the cellular immunology section of the Dental Institute, Frank
Ruscetti from the laboratory of Molecular Immunoregulation, and Bill Farrar
from the National Cancer Institute. By this time, I had earned tenure and was
secure in my position as a senior
scientist. I was pleased that people were working well together and our projects were benefiting from the
interdisciplinary efforts.
The work
consisted mainly of finding confirming evidence for our theory of an organismwide
information system linking the brain and glands with the immune, digestive, and
autonomic nervous systems. It was becoming clear to us that any receptor on an
immune cell would also be found on cells in the brain, and that at this molecular level there
really was no distinction between the mind and
the body. We were just beginning to ask the questions this knowledge
raised: What implications might this system of shared information have for our
understanding of disease?
And how does it help us to develop approaches to their treatment? It was this kind of inquiry that led our lab
to uncover a very significant finding, something only we were staffed and
equipped to pursue, and that catapulted us
smack into the middle of a race to find a cure for AIDS.
That Thanksgiving, Michael and I had announced to our families
that we were planning to get
married the following summer. Shortly after Thanksgiving, we were on our way to Maui to present our latest findings
at the annual American College of Psychoneuropharmacology Conference.
We arrived a week early with plans to do some camping and hiking in the
Haleakala Crater, a dormant volcano
whose long-ago eruptions had formed the island. Michael had mapped out a route
from Hanna, a remote ranching
town, up the difficult rear
slope
to the crest of the crater, where we would find a trail that would take us down
into the interior. After stopping to camp for a night in the crater, we would
complete our journey by climbing
back up to the crest
and then hiking back
down the rear slope, a three-day journey—one day for the hike up, one day to hike around the inside
of the crater after the ascent, and the final day for the descent back to Hanna. Ambitious, yes, but doable, Michael was certain of it.
Earlier
in our romance, he had introduced me to nature hikes, and while I thoroughly
enjoyed them, I didn’t have enough experience to judge my own limits. But I was
in love, and no challenge seemed insurmountable. We packed our equipment and
supplies and drove to the trailhead.
The ascent was
strenuous and took twice as long as we had planned, for halfway up what we had
thought to be a four-mile ascent we discovered was actually eight miles, with a
4,000-foot vertical gain. So a hike that had begun at dawn did not end until we
pitched our tent at 7 P.M. To this
day that hike remains my most grueling physical feat.
The headset I had
brought received only one station from nearby Hawaii, the Big Island,
but I managed to enjoy the
rock tunes and kept my spirits high.
Halfway
up we turned a bend and suddenly came upon a spectacular rainbow, as vivid and complete as any I’d ever seen. As we oooh-ed and ahhh-ed. I remember thinking we were being given a
sign that meant in spite of our misplanning, we were on the right trail, and
that this could apply also to the direction our research was taking back in the
lab. The rainbow, long a symbol to me of the promise of science to eventually reveal
ultimate truths, now graced our way, beckoning us on.
Once over the top, we descended into the crater,
and a truly magical
landscape unfolded before
us. The interplay of light and shadow over a
constantly changing terrain revealed reddish hues of cinder cones, black lava flows dotted by stunning silver swords jutting
up out of nowhere, a moonscape
of vast emptiness. I remember
feeling a sense
of sacredness as we hiked
along the solitary trail, a certainty that this was a special place and
we were walking on holy ground. Haleakala, the House of the Sun, where myth
until had it that the demigod Maui had captured the Sun and made it do his
bidding! All of this—the gorgeous nature, the mystical aspect, and the sheer
physical challenge—was having a profound effect on me, and I experienced an
expansion of my heart and consciousness that left me in a state of deep awe and
humility.
When we returned
from our unexpectedly heroic journey, we were exhausted and dehydrated, yet
exhilarated in our triumph. Looking back, I see how our ordeal was a harbinger of things to come, of the labyrinth that lay ahead and
would
consist of infinitely more twists and turns than our hike into the crater, and of an infinitely
more strenuous journey than our hike up the rear slope. In our work back at the
lab, we stood on the brink of an abyss we would soon descend, completely
oblivious to the events that would lead us through the war- torn land of
the AIDS establishment and toss us
from our cozy Palace nest.
Michael drove
the rental car to our rented condo, where we collapsed after soaking our aching
muscles in a hot Jacuzzi. That night, our first spent indoors since we’d
arrived on the island, I slept deeply, lulled by the sweet smells and gentle
sounds of the ocean lapping at our lanai edge. I was rested and refreshed the
next day when I arrived at the conference and took my place among the speakers
for the opening session, entitled “AIDS and the Brain.”
OVERLAP
An exciting series
of events, precipitated by our investigation into the link between the immune system and the brain, had brought us to the Maui
conference and had placed us at the doorway of the then emerging arena of
AIDS research. It had all begun when Michael and I discovered that many peptide
receptors thought to be confined to the brain were also found on immune cells.
Once we knew that, we began to wonder if receptors that were found on immune cells might be in the brain. A fortuitous phone call from an
immunologist proved to be crucial to the work we were about to begin. Knowing
of my interest in neuroimmune connections because of the papers
I had published. Bill Farrar called me one day to discuss his own work in that area.
When I told him we were trying to map immune
receptors in the brain, he offered to supply me with the antibodies we would need to help us find them.
The next morning a tall blond bodybuilder type, dressed in shorts and sandals,
showed up in my office, carrying ice buckets of antibodies—the delivery boy from Bills office,
I assumed (since
scientists don’t tend to look either so casual
or so athletic). But in fact it was Bill himself. Once I saw him in action, it
was hard for me to believe I’d ever
mistaken him for a delivery boy, for Bill had a decisive and masterful way of
getting things done, thanks to the years he’d spent as a navy fighter pilot
launching fighter planes off aircraft carriers. For all my feminist leanings, I
was intrigued by the idea of working with someone whose style and presence were
so quintessentially masculine.
Some weeks after we’d begun our immune-receptor mapping,
I was even
more
intrigued when Bill called to tell me that three different research teams had
more or less simultaneously discovered the receptor that the AIDS virus used to
enter and infect cells—the T4 receptor. The T4, was found on key lymphocytes in the immune system, called
T4 or CD4 lymphocytes. A severe depletion of T4 lymphocytes is one of the
signals of the presence of the AIDS virus, and also one of its deadliest
effects, for it is the lack of these lymphocytes that makes AIDS victims susceptible to the normally
benign microbes that cause their numerous
and sometimes fatal opportunistic infections.
No sooner
did Bill deliver
the news about
the T4 receptor being the entry
point for the AIDS virus, than he began grilling me excitedly. “T4,” he said,
the words spilling out of his mouth. “I know I gave you an antibody that would
bind with the T4 receptor.
Have you used it yet? Did you find anything
with it?”
“You bet we did!”
I answered triumphantly. “And it went right for those receptors and lit up the
brain like a Christmas tree.”
Subconsciously,
the significance of our T4 mapping began to dawn on me. If this receptor was
the entry point for the virus in the body, then it must also be the point of
entry in the brain as well. And if this was so, our expertise in receptor
mechanisms could lend itself to a deeper understanding of how this process
actually happened, and maybe even of how it could he stopped.
We also began to
suspect that we might be able to use our knowledge of the virus receptors in
the brain to help explain “neuro-AIDS,” the dementia, memory loss, neuropathies
(nerve degeneration), and depressions that were just starting to be recognized
by neurologists and psychiatrists, who were now seeing more and more AIDS
patients with these symptoms. Very little research attention had been given to
this aspect of the disease. Since virologists and immunologists had no contact
with psychiatrists, much less neuroscientists, their awareness of the growing
phenomenon of neurological complications was limited, and what little they did
know about it they tended to attribute to the understandable emotional
depression of patients who were critically ill.
Now that we
knew the T4 immune receptor was the entry point for the virus, we would focus
our brain-mapping effort on it. We knew that no one else would be looking for
immune receptors in the brain, because almost no one else even believed they were there—as
was clear from events then taking place
right across the way.
ENTER HIV
Within a few
hundred yards of where we were working, in the part of the Palace where people looked only at the
body and not the mind, a team of NIH immunologists and virologists at the Institute for Allergies and Infections Diseases (NIAID) was following the newly discovered human immunodeficiency virus, HIV. Earlier, Dr. Robert Gallo
of the Cancer institute at NIH had made headlines when he announced that HIV was the cause
of AIDS, a disease that had first been identified when it broke out quite
suddenly in the male homosexual population. Gallo showed that the HIV was
infecting the cells of the immune
system, using their DNA to replicate and spread. As a result, the immune system was severely compromised, allowing opportunistic diseases to proliferate and eventually
kill the host. So the NIH scientists, like us, were focused on how to prevent
the HIV virus from doing its deadly work.
But their
approach would, of necessity, be quite different from ours. With a few notable
exceptions, among them the knowledge that the rabies virus used the
acetylecholine receptor, virologists had never gained much understanding of how a virus gets into a cell. The process they most favored, viroplexis, was frequently described as
the virus somehow glomming on to the cell surface and then fusing with the
outer membrane to gain entry. The “glomming” step was a big unknown and not considered too important. Up until this point, virologists had been interested mostly in
the molecular processes that regulated the reproduction of viruses—in other words, how did a virus replicate
itself? And the answer,
insofar as it was known, was that viruses replicated autonomously inside cells, where they could not be
attacked without drugs that also destroyed the cell. Because of this, any cure that
attempted to interfere with the
replication of a virus after it had entered and “infected”
a cell would be extremely toxic.
Nonetheless, this became the focus of their research
effort.
We could,
however, go after the virus in a different way, for the question of how the
virus could find and enter an immune cell was no stumper for a neuroscientist.
We could easily understand how viruses might operate like exogenous ligands,
binding, just like peptides, to specific receptors. Viruses were known to contain various proteins on their surfaces
that were important in determining which cells
they could infect.
Thus, different viruses
exhibit what we term a “tropism” for different cells,
so that we would say, for example,
that the HIV virus is T4-tropic. To a neuroscientist it made perfect
sense that some of these viral invader proteins might resonate with some of the
body’s own molecular
vibrations. In other words, we believed that there must be viral keys that could unlock
receptor keyholes, and thereby enter the cell.
To see it under
a microscope, the HIV virus looks like something out of Star Wars, a sphere whose surface is covered by hundreds of sharp
protein spikes. It is this part of
the virus, the surface protein envelope gp120, that has a particular molecular
sequence that allows it to latch on and bind to immune, brain, and other cells, initiating infection and, as
we and a few others were to discover, many
other receptor-mediated processes
important in causing the signs and symptoms, indeed the disease, of AIDS.
![]()
Once we had
zeroed in on the T4 receptor, Joanna Hill, the skilled neuroanatomist of our
group, generated gorgeous images of its autoradiorgraphic distribution pattern
in rat and monkey brains.
And then one day shortly afterward, I received a chance call from Dr. T. Peter
Bridge, an NIMH psychiatrist with an interest in
psychoneuroimmunology, who was organizing a symposium on his new interest area,
neuro-AIDS. “Do yon have anything on AIDS
and the brain?” he asked me. Slightly stunned by his presence, I told him what
we were up to. And it was because of that conversation that we received an
invitation to present our work at the symposium on AIDS being offered at the 1985 American College of
Psychoneuropharmacology Conference in Maui, Hawaii.
INTERVENTION
The descent from
Haleakala had, if anything, been harder than the ascent. I hadn’t expected the
fatigue of the descent, thinking. “Ah, it’s all downhill from here.” but as
anyone who has done this sort of thing knows, the faster pace down quickly puts
the burn to the quads. So when I showed up for the meeting on the first day of the conference, my body ached exquisitely with the pleasure
of a hard job well done. My mind,
however, was unusually
quiet as I listened to my
colleagues
present their findings about AIDS, realizing for the first time that the word pandemic, or global plague, was no
exaggeration when applied to this rapidly spreading disease.
My knowledge of
the disease had been limited to what I’d read in the newspapers, and, of course,
I was familiar with the announcement by Bob
Gallo’s office that the cause of AIDS, the HIV virus, had been found by
researchers in his lab. It had made quite a stir when Margaret Heckler of
Health and Human Services announced that huge amounts of federal money were
being allocated to the NIH for the battle against AIDS now
that there was a known virus they
could target. And, occasionally, news and gossip wafted across the lines, from
NIH to NIMH, via Bill Farrar, who had one foot planted in each camp. But mostly I
knew nothing, for reasons best left to the account in Randy Shilts’s book And the Band Played On, where it was
explained how little information the public had access to at that early stage.
Now I was watching a slide show depicting the terrible agonies of AIDS
sufferers and hearing how the virus destroyed the immune system and ravaged the
body, exposing its host to any number of rare but lethal opportunistic infections. For the
first time, I began to think about
the human cost of this disease, and a sense of urgency came over me, a strong desire
to make some kind of contribution to the efforts
of researchers to understand and treat it.
When it finally became my him to speak—I
was the last one on the program
—I stepped
up to the podium and presented our findings. I described how we
had found a T4-like molecule in our brain mapping, with high densities in the
hippocampus and cortex. The slide Joanna had made of the monkey brain came up,
projecting the colorful pattern T4 made in the brain for all to see. As I gazed at it admiringly, I suddenly became aware
of a curiously altered state of awareness. I began to speak, but my voice
sounded strange, as if it were coming from a distance.
“Our
data clearly suggests the T4 receptor could be a neuropeptide receptor, since its pattern is reminiscent of the patterns
of known brain peptide receptors,” I reported, the words echoing
as they left my mouth. And then, following that, seemingly from out of the
blue: “If we could find the body’s
natural peptide ligand that fits the
T4 receptor, it could yield a simple, nontoxic therapeutic to stop the virus from entering the cell.”
There was a
hushed silence as both my audience and I let these remarkable words sink in.
Had I just proposed a discovery path for the cure for AIDS? It was the very
first time such an idea had occurred to me.
And then I heard a louder
voice, this time not recognizable as my own and
not spoken out loud, but echoing inside my own head! It was a strong male voice
that commanded: “You should do this!”
I certainly
wasn’t used to hearing voices
comment on my lectures, and at first I assumed the command was some kind
of hallucinatory aftereffect of the exhausting hike up the volcano. But the
logic of the approach was so compelling that I trusted that voice. Even the
fact that it was distinctly male didn’t rankle my feminist sensibilities, because whatever that voice was—hallucination, voice from God, my own higher wisdom—I knew exactly what it was
telling me to do! My whole scientific career, it seemed, had been a preparation
for answering the question I had just proposed
to myself: What natural peptide
fits the HIV receptor in the brain and in the immune system, and how can we make a
synthetic version of it to block the receptor and thereby stop the entry of the
HIV virus?
Hadn’t this been the route followed
once before, when we all went looking for the enkephalin/endorphin
discovery? The CD4 receptor wasn’t there exclusively to bind to the virus, any
more than the opiate receptor existed to bind
to morphine! It made perfect
sense, and I was mystified
that it had never occurred to
me before that moment. My thinking was now traveling down what was for me a
well-trodden path of theoretical trailblazing, which had begun with the discoveries of the opiate receptor and its endogenous ligand, endorphin. Just as before, we had a receptor (T4),
and now we would go looking for its unknown ligand. But this time we would use
a computer to help us find it.
I could
barely wait until the next morning to call the mainland and have my lab set in
motion the process needed to begin the quest. Bill Farrar was is on hand to
direct the computer that would help us search a worldwide peptide database. We
were looking for a molecular sequence identical to that of the external viral
envelope of the HIV virus, the gp120, which was the part of the virus that fit
into the receptor.
The
identification of a receptor entry path for the virus, and the subsequent
description of the T4 receptor, had suddenly opened up many new avenues for
AIDS research. Thus, there were soon a number of government and industry teams
doing the same thing we were doing—looking for pieces of gp120 that bound to
the T4 receptor—but doing it much more indiscriminately. Since their method
involved making nearly every possible peptide permutation, and since there were
over 600 positions for amino acid candidates to be filled in the sequence, their chance of success was analogous to throwing 100 monkeys and
100
typewriters up into the air and waiting to see if, eventually, the complete
words of Shakespeare would appear, printed out perfectly to the letter.
Not that our
path was as direct as we had hoped it would be. We had thought that if we
designed some well-thought-out computer searches, we would quickly arrive at
the sequence that would enable us to identify the one natural liquid; but what
we got was not nearly so clear-cut. The computer identified multiple sequences
of other proteins that closely matched the gp120 sequence, none of which, alas,
were underlined in red with a note that said. “This is the one!” We were going to have to put our seat-of-the-pants feeling for the material into action so that we could narrow the
search down to just a few of the numerous candidates for synthesis and further testing.
We’d simply have to hope that one of our hunches would pay off in the
discovery of a substance that would act in place of the still-unidentified
natural ligand, and that it would be a good enough mimetic to successfully
displace the gp120 from the receptor, bumping it off at the point of entry.
So one night, I
bought home the printout of all the possible sequence our computer had
generated and spread it out on the dining room table—but not without a sense of
foreboding about what would happen if we chose the wrong one. Pharmacology is
an exacting science, and there are no “almosts” or “close tos” If one letter of
the sequence was wrong, or we missed one, then our synthesized substance would
be useless to us, failing in any tests or assays we would do to prove its
abilities to displace the virus. We could he very close hut never know it.
Together Michael
and I pored over the pages of letters for a week, It was Michael who finally
made the decision to focus on an octapeptide contained in the Epstein-Barr virus,
another “lymphotropic” virus, albeit for B cells, not T cells, which we
guessed, rightly or wrongly, might use the same receptor as HIV. It didn’t, but as we were eventually
to discover, we had picked a winner, having gotten to the right place for the
wrong reason.
I placed a call
to my old friend Dr. Jaw-Kang Chang at Peninsula Labs in San Francisco. It was
New Years Eve, and, as I suspected, he was working late in his lab. In a
near-replay of what had happened ten years earlier with enkephalin, I carefully
read him the sequence of the eight-amino-acid peptide we had picked and asked him to synthesize it for me.
Since the first amino acid in the sequence was alanine (just like the one I had
asked Chang to change to make the long- acting
version of enkephalin), I instructed Chang to make three D-alanine analogs for a total of four
closely related octapeptides. Again, I swore him to secrecy and told him he’d
have to do it without asking too many questions.
Chang
accepted the challenge, and two months and $10,000 of the taxpayers money
later, we had the four synthesized peptides in our hands, enough to begin our
tests.
Bill Farrar was the broker for a deal with a lab in Frederick. Maryland,
that had made the HIV virus and separated out its various protein components, essential ingredients that we would need.
He got us the viral protein we needed, the
gp120, which we then had labeled with radioactive iodine. Now we had both of the crucial elements on hand, the
synthetic peptide and the radioactive viral protein, and we were ready to begin
our receptor-binding assay to see what these peptides would do.
I remember
feeling excited to finally begin the experiments, hut also apprehensive, as if
I were about to dive into a swimming pool drained of water. Everything about
this project, it seemed, had depended on some hard-to-fathom combination of
intuition and/or mystical intervention and/or sheer good luck, all of which were somewhat
suspect to my scientific mind at the time. The direction had been dictated by a
voice in my head while I stood at a podium in Maui, and the choice of sequences we’d made, while based on a firm rationale, had invoked a heavy dose of intuition, a fact that
other researchers would either marvel at for decades to come if we were successful, or
ridicule mercilessly it we were not.
Now
the moment of truth was upon us. Would our magic peptides do the deed and prove
us right?
Michael and I
distributed half of our synthetic peptides to collaborators Frank Ruscetti and
Bill Farrar, who were working at one of the Cancer Institute’s many labs, and
we set to work using the remainder ourselves. The goal of Frank and Bill’s
assay was to show that the peptides blocked the virus from growing in human
cells. Frank was the only person other than Bob Gallo himself who had access to
the actual virus from fresh patient isolates, not the old stuff passed around
in lab cultures for many years. This would prove to be a crucial advantage to us, because
while other researchers were enticed by the ease of
using these lab-adapted strains, they often ended up wasting much effort, resources, and precious time studying what
would only years later be revealed as artifacts that is, phenomena that wen not natural to the virus,
that were not the
way the virus behaved in humans.
The receptor-binding assay our lab was developing was aimed at
determining whether the test peptides could actually block the attachment of
the viral protein envelope gp120, even displace it from the receptor on the T cell. If it did, we had a potential therapeutic, a new drug that we could begin
to develop as a possible
treatment for AIDS.
The hands for the assay belonged
to Robbie Berman, a newly graduated Yale man
spending the summer at the
Palace, before going on to medical school.
Robbie
came into the lab every day and set up the test tubes, pipetted the many
different ingredients into them, ran the experiment, and then brought me the
numbers. He was brilliant and secure, performing every tiny step in the assay with the precision I required, enduring
many hours of my thorough cross- examination about the daily progress of the
experiment. He was as young and energetic as a typical graduate student but as
smart as a postdoc, and best of all, from my point of view, he lacked the kind
of oversensitive male ego that required an excess of diplomacy. We were able to work very
closely together as he cheerfully tolerated my leaning hard on his shoulder
barking out minuscule technical changes, something that would have caused just
about any postdoc to get up and exit in a huff.
Before
Presidents’ Day weekend of 1986, Robbie and I did the key experiment. Together we dissolved the
peptides into a solution of radioactive gp120
using a number of different
concentrations, and allowed
them to react with the T4-laden membranes. Since we had a three-day
weekend before us, and we were apprehensive that the counts would be so low
that we would have trouble
getting a meaningful signal off them, we decided to set the counter to counts
of twenty minutes for each filtered sample—much longer than usual. It was a luxury
to be able to do such a patient, careful
measure, and, as it turned out, one of several instances of
good luck.
On Tuesday
morning, I arrived early and eagerly pulled the tapes from the counter,
scanning the numbers. It took only minutes to realize that we had something
here. The counts showed that our peptides had knocked the binding of gp120 down
to half, competing with the HIV for the receptors, just as we had theorized
they would. What was particularly exciting was that the data showed that while three of
our four peptide analogs worked, the fourth was almost inactive. This was a crucial test, because it demonstrated some
specificity and selectivity in the binding inhibition, the hallmark of a receptor-mediated event.
Just hours after
our Eurekas had died down, news came from Frank and Bill’s lab that the
peptides had also inhibited the virus from growing in human cells in test
tubes. There was about 80 to 90 percent effectiveness. But Frank, who didn’t
get excited too easily, was quick to point out the apparent
downside of his results. “Well, Candace, three worked
and one didn’t.” Even the fact that one hadn’t worked turned out to be good
news for us, however. When we compared the data from the two labs, it was clear not only that our most active peptide
was
also
his most active peptide, but that a different peptide was also inactive in both
his and our assays. This type of result, showing comparable relative potency in two very different labs using two
completely different methods, was the old standard for a receptor effect, and
it clinched it for us. We knew we really had something.
We were ecstatic
that our prediction had seemingly been confirmed! Perhaps we had found the substance that would
prevent HIV from entering the cell and replicating. And a bonus surprise was
that the concentration of peptides it took to occupy the receptor and
accomplish these results was astoundingly low. In fact, this computer-generated synthetic peptide compared in
sensitivity with the most potent neuropeptides themselves. Later, when we did
the calculations, we found that an effective concentration was equivalent to an aspirin
tablet dissolved in the
amount of water
contained in a railway tanker
car. We named
our child of the new paradigm Peptide T, the “T”
referring to the presence of threonine, the dominant amino acid in the
synthesized substance’s molecular sequence.
We were so flush
with the success of our experiments, we’d completely forgotten what our
original goal had been—the identification of the endogenous ligand, the body’s
own natural substance that binds to the HIV receptor on brain and immune cells.
We had found our mimetic, Peptide T, and our direction seemed clear: We should publish our findings and test our new
therapeutic through human trials.
However, the search for the endogenous ligand was not over, even though
we ourselves had gotten distracted from it. A few months later, our colleague Ed Ginns, a
molecular biologist whose help we had sought, found the ligand in a Peninsula
Labs catalog. He’d been flipping through the pages that listed peptides available from the
manufacturer when he came across what he recognized as a sequence identical to
that for Peptide T. Right there, contained within the printed sequence for one
of their catalog peptides, was what we had been looking for—VIP, our
vasoactiveintestinal peptide.
As it happened,
we knew quite a bit about VIP. It’s found in the frontal cortex of the brain, in the thymus
gland, the gut, the lungs,
some immune cells,
and parts of the autonomic nervous
system. Eventually, we would come to
understand how the HIV virus competes with VIP for receptors on the surface of
immune and brain cells, and some other cells as well, latching on when the VIP
molecule is not occupying them. Just how much VIP the receptor is “dripping
with” at any given moment will affect the system’s susceptibility to infection
at that time.
Much later, I was to Speculate
about what emotional
tone VIP was associated
with.
Could a particular emotion generate or suppress quantities of VIP in the body, affecting how much of it was available to block or leave open a pathway for the HIV to enter the cell?
Clinicians have the impression that increasing Self- esteem seems to slow the
progress of the disease. This leads me to speculate that VIP might be the
hormonal manifestation of self-love, just as endorphins are the underlying
mechanisms for bliss and bonding.
OBSTACLE COURSE
The next
challenge was to describe our Peptide T findings in a short, concise paper and
have it reviewed for publication in a scientific journal. We hoped that this
would be easy, a swift fait accompli, to allow us to go on to our next major
step, developing the drug through human trials. But we were also aware that our
approach was radically cross-disciplinary and would be difficult for reviewers
to understand. Also, we had based
our work on concepts not altogether acceptable to most immunologists and
virologists at the time: that the brain and the immune systems have many
cell-surface receptors, and that viruses use these receptors to enter the cell.
Believing we had
a piece of an enormous discovery on our hands, we decided to try to position our paper in the most
prestigious and widely read journal, Proceedings
of the National Academy of Science, PNAS is the journal published by the National
Academy of Sciences,
a federally funded
organization founded in
Abraham Lincoln’s time that still retains many customs dating from that era
(including the opportunity to blackball potential new members, a practice many
believe encourages the cronyism that is its hallmark). One of the academy’s
more antediluvian traits at the time was that only about 2 percent of its members were women.
PNAS is a slick and beautifully produced
journal that has a very high impact, as witnessed by the number of times its
articles are cited in other journals.
Through
an elaborately cautious procedure that supposedly discourages favoritism,
members of the academy can submit a limited number of papers to the journal
each year, their own or those they think important and worthy by others. But
despite the apparent safeguards against favoritism, having a few academy
members as your friends is the only way to guarantee quick, prestigious
publication—provided one of them can be persuaded to relinquish one of his own
precious slots.
What we needed
was an academy member who would agree to evaluate our paper and then find two
reviewers to give it the nod, at which point it could be submitted for
publication. We had tried to do this once before with our earlier paper showing
how we’d found the T4 receptor in the monkey brain. But that paper was still circulating unpublished,
having made the rounds with no success. In
fact, it had been rejected in a particularly humiliating fashion by someone for
whom I had had great respect. Frank Ruscetti had suggested we give it to the
virologist Albert Sabin,
a visiting emeritus
scientist at the NIH, who had years ago created an oral polio vaccine
that became more popular than Jonas Salk’s injections. I was eager to meet Dr.
Sabin and naively expected that he would be more than glad to read our paper
and wave us on into the journal. I sent the paper over to him by messenger and,
two days later, with Michael along as coauthor, visited the famous doctor in
his tiny office located in the basement of the NIH library.
Remembering how
my children had been inoculated with the Sabin vaccine. I gushed about how
honored I was to meet someone who had a human vaccine named alter him. Sabin
accepted the praise but then, without warning, began to tear into our paper. In a mounting harangue,
he proceeded to critique it, frequently referring to his
handwritten notes, in terms that made no scientific sense to either Michael or to me.
Finally, his rant
drawing to a close, he said, “And what’s this about virus receptors in the
brain? We cured polio without needing to invoke virus receptors in the brain—or anywhere else!”
To Sabin, this
new idea was flatly unacceptable. He slid the paper across his desk and, with
unconcealed scorn, announced he positively would not recommend it for
submission to PNAS. At this point I
lost my ability to fight back tears, so huge was the gulf between what was
happening and what I’d expected. I signaled Michael to leave and got up to make
my way to the door, when suddenly Sabin’s mood shifted. Seeing tear roll down
my cheek, his face lit up, and he
even chuckled as he escorted us out. “I can’t believe it I made Candace Pert
cry!”
Eventually, I
got over the shock of Sabin’s personal hostility to me, and I was able to
forgive him for the extremity of his reaction. This happened when I realized what an affront our paper must
have been to him, a slap in the lace to his somewhat tentative status as the
man who had bested Jonas Salk. But back then, this bizarre event had only left
me hurt and confused.
In looking for a champion for our new paper, we decided to ask for help from
Fred
Goodwin, my boss at the Palace after Bill left. Fred had been closely following
my work and generously supporting my lab for several years, and he instantly
understood the concepts proposed in the paper: but he also recognized that our
more specialized peers probably would not be able to do the same. To the greater scientific community, our
paper would seem like it came from the Tower of Babel, a hopelessly
multilingual report, and its significance would be missed unless it was guided
through the process by someone who Fred had under
his direct influence. With that in mind, he suggested we seek the endorsement
of one of the Few NIMH scientists who was a member of the academy, a well-known
neuroscientist who had made his mark with the first functional brain scans.
We sent the
paper to our new potential champion, but after many weeks we had still heard nothing from him. However,
it wasn’t unusual for the chosen reviewers to take up to eight weeks before
responding to a paper, and since this was the case, well, we’d just have to he
patient, Fred reminded us. Meanwhile, Michael and I prepared for our rapidly
approaching wedding in Lyme, Connecticut. Our hope was that we’d get word about
our paper before departing, just in case we needed to be on call for any changes or requests to fix parts of it.
The silence
continued. We pleaded with Fred to prod the foot-dragging scientist, to find
out if the reviews would be in before our June 7 wedding, something Fred did
with reluctance. Our plan had been to leave D.C. and drive to Lyme in plenty of time to get our
marriage license at the Town Hall and supervise details of the elegant wedding
on Saturday. But we didn’t want to leave until we got the long-awaited response
to our paper.
The wedding was
to be a dream come true, the wedding I’d never had, since my marriage to Agu
had been arranged rather hastily, a no-frills event. Michael and I had
organized an extravaganza, complete with engraved invitations for over a hundred people, fancy tents on the
lawn, and elegant catered eats. Many hours of planning had gone into it, and we
looked forward to thoroughly enjoying
every minute of the result.
At the last
possible moment, two days before the wedding, the much- anticipated phone call
came. Could we come over immediately? We went to meet with our potential
champion at his office, feeling hopeful and certain that this long delay could
only mean our paper had passed muster with the two required reviewers. But only
minutes into the meeting, the doctor began to sputter and things took a dive.
“Virus
receptors, virus receptors,” he bellowed, his face dark red, spittle flying.
“No one I know has ever heard of a virus receptor!”
In what was an
incredible instant replay of our earlier encounter with Sabin, he made it
perfectly clear, as he shoved the paper across his desk at us, that he wasn’t a
virologist and couldn’t possibly submit the paper to the journal. This time I
shed no tears over the hostility directed at our efforts.
Later that same
morning we left to drive north, fuming that we’d put everything on hold only to discover that our paper had simply
been gathering dust all those
weeks. We stopped to shop for my wedding dress and trousseau at the White Flint
Mall, arriving in Lyme with just one day to get our marriage license. When we
got to the Town Hall, a clerk abruptly informed us that in this township there
was a four-day wait between application and issuance of the license, a fact
that threw us into a panic. Should we just go ahead, have the wedding illegally
and fake it? This kind of sham didn’t appeal, especially since I had wanted
things to go so perfectly. In my pleading. I mentioned that my uncle Bill Beebe
was the town treasure, a fortuitous connection that enabled our by
now totally sympathetic clerk to help us out with the higher-ups. In the end, a
judge wrote a special edict to enable us to skip the wait, and Uncle Bill, the church choir director, who was a talented
musician as well us our savior, played “Somewhere Over the Rainbow” on the organ for our walk down the aisle.
We spent our
honeymoon in Provincetown, on the tip of Cape Cod, biking in the rain. It was
blissful, a much-needed retreat, but as we passed through the streets of this community, long-favored by
gays, I couldn’t ignore the main ravaged faces and bodies I was seeing.
The knowledge that we had a
contribution, one that could possibly lead to a treatment for their disease, if
only we could somehow get out the gate with it, was immensely frustrating.
During one long
ride along the sand dunes, we saw a rainbow, an image that had also been taken up by the gay community as a
symbol of pride and unity, and again I felt
affirmed in my quest. It seemed that the rainbow
had been following
me since the beginning of my career,
and now it was even more visible,
a symbol for others as well as myself, a symbol for those who could benefit from the work I was doing.
On our return,
Fred was apologetic about not having been able to persuade his man to fall in
line with our plan to pull off a quick and clean publication. But, beyond that,
he had no other suggestions for us. As noted earlier, the NIMH has very few
members of the academy, which may seem odd for such a prestigious institution,
but scientists have a longstanding prejudice against psychiatry and psychology,
a reluctance to acknowledge the behavioral sciences as authentic science, and they admit only a small number from those disciplines to their
pantheon. Hence, Fred had few personal
connections within the academy.
We moped for
days, but our spirits took a turn for the better when we found that awaiting us
in our pile of mail was an invitation to the NIMH’s fortieth birthday party,
an event that was to take place on June 26, 1986.
the exact date of
my own fortieth birthday! The fact that the NIMH had been created through an act of Congress on the very
day I was born made me feel that the birth of the neuroscientific approach was
closely aligned to my own birth, which gave me a renewed sense of hope. Furthermore, this event would bring me together with my old mentor, Dr. Sol Snyder, a
longtime academy member and, perhaps, if he had thawed sufficiently from the Lasker
incident, a potential benefactor—the key to getting our paper published in the
academy journal.
The NIMH party
was an elaborate bash with a sumptuous spread of food and plenty of awards
being handed out. I spotted Sol almost immediately and approached him at the
very first chance. We made the usual small talk, tense but cordial, at least on
the surface. Then I decided to come right to the point, and I told him of the trouble
we’d been having
with our paper.
He listened politely, but when I asked him to take a copy of it, he put both hands up and backed away, shaking his head, pleading
ignorance about virology and saying he couldn’t possibly do an evaluation. I stood there
alone, feeling embarrassed and hurt, and contemplated the significance of this
latest rejection.
Had it not been
for the Lasker incident, I believe Sol would have leapt at the chance to help
his former student advance a new drug using receptor theory, especially one
discovered using an adaptation of the radioreceptor assay we had developed
together. It was hard to swallow, but I had to accept the fact that my earlier
actions had cost me Sol’s support at a time when it might have made all the difference. Yet, in spite of this
regret, I knew that had I never been handed the
challenge of struggling back from ostracism and disrepute, I might never have gone in the direction that led me to
the discovery of Peptide T.
Clearly, this
was turning into more than the usual effort to get a controversial paper
published.
Michael and I
were now completely out of ideas about potential sponsors for our paper. One
night, to divert ourselves from what we hoped was a temporary impasse, we rented
the video of Amadeus. In the film, the genius Mozart is given a review by his peer,
the jealous musical
expert Salieri, who pronounces his latest composition as having “too
many notes.” It struck us that the problem with the Peptide T paper was that it
also had too many notes, causing the “experts” to find it too unfocused to comprehend. Most papers reported
on only one or two
facts,
allowing the writers to stretch out the data and publish two or three more
papers down the line. But in our case, thinking we might have just this one
shot, we had wanted to get the whole story succinctly and efficiently told in
the five- page limit, and so had packed the paper full of details. In the
paper, we had included the color illustration of the distribution of T4
receptors in the monkey brain, a brief description of how we arrived at Peptide
T’s molecular structure, and figures
showing the drug’s ability to block access
of the virus to the receptor, as revealed by the binding
experiments Michael and I had done and by the infectivity experiments Frank and
Bill had done. Finally, and possibly most annoying of all to our peers, we had
included a brief discussion of how the synthesized peptide might be used as a
potent antiviral therapeutic to prevent the HIV virus from entering cells. What
we needed in the way of a reviewer was a Mozart, for whom too many notes were
not a problem!
It was Clarleton
Gajdusek, a Nobel laureate from the National Institute of Stroke and
Neurological Disease, an NHI, not NIMH, academy member, who finally did the
deed for us and got our paper into PNAS.
Even though he
resided in the “body” section of the Palace, Gajdusek was a pediatric
neurologist who specialized in diseases of the brain, especially the viral
kind. Michael knew the renowned professor from his undergraduate days, when,
during a visiting lecture, Gajdusek had regaled him and his classmates with
tales of virus hunting in the South
Pacific. I’d never met him myself,. but from what I knew about him, he was a
genius who had already ascended to sciences highest ranks, someone with no
particular interest in the AIDS arena and no political agenda, and therefore
he would probably at least agree to give it a look.
I took a deep
breath and picked up the phone. When he answered, I told him who I was and that
I had a paper I’d like him to evaluate for possible submission to PNAS.
He asked a few intense but brilliant questions about the content of the paper,
and then, after a brief silence, responded.
“Yes, definitely.” he said firmly. “Get me the names of scientists you
know who can understand it and review it for errors. I’m flying off tomorrow
but I’ll be back in a couple of weeks.”
I exhaled.
The whole transaction had taken less than a hall hour.
As promised, he
had the paper reviewed, and when the science of it was confirmed as acceptable,
he submitted it. We received notification of its official acceptance less than
two weeks after my phone call to Gajdusek. By September, one month after it was
submitted, the paper went to press, slated for publication in December 1986. We had found our Mozart and solved the dilemma of the
paper that had too main notes.
TRIALS
It’s to the credit
of the Palace to say that Peptide T could only have been invented there. Only at the Palace was there a critical mass of
free-flowing money, brilliant minds,
and state-of-the-art equipment all assembled in one location. The irony was that the Palace, having given birth to a drug like Peptide
T would never give it the support it needed for full testing and development.
The reasons for this were many, some related to my own tactical errors and past history, others the result of the harsh
realities of Palace politics and government funding choices. But underlying all
of it was a very fundamental but less visible drama¬the shift from old to new
paradigm. Conceived by believers in the mind- body connection, Peptide T was
truly a child of the new, more holistic paradigm. And that was a big problem
for a large establishment institution.
The reigning
paradigm held firmly to the denial of any meaningful connection between mind and body as they pertained to health and disease. Itself
a product of this old-paradigm thinking, the Palace in its institutional structure mirrored
the Cartesian split: The NIMH attended to everything above the neck, while the
larger, better-funded NIH took care of everything below. And although
there were occasions when the twain did meet, those were the exceptions,
not the rule. AIDS was a disease of the body, and it was the body boys at the
NIH who would be trusted to come up with a treatment.
My sojourn into
the AIDS arena in some ways paralleled my earlier foray into the world of cancer research, when we failed to convince
the narrowly specialized Held
that neuroscience had something to offer in developing treatments for cancer. Now I was again confronted with the
deeply ingrained theoretical division, not only between body and mind but between
separately studied systems of the organism. Only this time I was joined by other scientists in my efforts, an interdisciplinary team of some of the brightest and most
forward-thinking researchers at the Palace,
many of whom were willing
to venture out and cross lines. Still, I was placing in a much bigger
league now, dealing with political funding issues that we hadn’t come up
against before.
Huge
amounts of money were coming down the pipeline for AIDS research, and to get a piece of the pie, we needed the
goodwill of powerful people in high places,
something we soon found out we did not have.
• • •
FOR
MONTHS I had been banging
on Fred’s door,
trying to get in to see him and discuss moving Peptide T to the
next level, the phase I clinical trials. Fred’s support of Peptide T had been
unwavering until a moment of truth, which occurred
early one Saturday morning during a government budget meeting when the director
of the Institute of Allergy and Infectious Diseases took some $11 million he
had put into NIMH back out of Fred’s pockets. The rationale for this sudden
withdrawal, the director informed him, was that development of antiviral AIDS therapies was not the business of the NIMH,
and Fred certainly didn’t need that much money to pursue a nonstarter like Peptide
T.
And Fred was
avoiding me because he already knew what I learned only later, which was that the NIH and the Cancer
Institute had their own candidate for
an AIDS treatment, a highly toxic, very conventional, but promising, drug
called AZT. They’d already reserved the beds in the clinical center for the
trials they planned to conduct, and there wasn’t an inch of space left over for
anyone else, even in a matter of life or death.
AZT was a
chemotherapeutic drug, originally used for cancer in the early sixties, which
worked by terminating virus replication. But the price to be paid for this benefit was a
big one: AZT undermined a person’s health by destroying not just the virus but
also healthy cells, particularly those of the immune system. The resulting side
effects, or toxicities, were sometimes severe, although some patients could
handle them better than others. AZT showed some promise in reversing symptoms
of AIDS and giving patients valuable time, but it could not be considered a “cure,” since, in a
process similar to what happens when chemotherapy is used for cancer, it causes
the virus it attacks to eventually develop resistance so that the disease
usually recurs.
Unaware that the
Palace had decided to concentrate totally on AZT. I continued to spin my
wheels, trying to find out whom I needed to talk to and what forms I was
supposed to fill out to enable us to proceed to the next logical level. I was
getting nowhere fast.
In retrospect, I
see that in my haste to effect a swift and clean entry onto the turf of the
body boys, I had failed to court favor. Perhaps I should have gone begging, hat
in hand, to an NIH AIDS power boy for help in getting our paper published. But
my thinking was that the sooner we got our paper into print, the sooner testing
could begin on people with our new drug, and I didn’t want to waste time by
doing what I thought of as massaging male egos.
How incredibly
naive I was! And the hubris I had! Who was I but a fairly
accomplished
bench researcher oblivious of the fact that testing a new drug was the big
time—showtime!—for most scientists,
and I hadn’t even read the script. Stumbling into a scene where major players
were about to sit down and carve up the funding bonanza
AIDS research promised
to be, I was clearly
an intruder. It is understandable, in retrospect, why
the arrival of Peptide T, coming out of left field, was not greeted with
enthusiasm.
Up until that
point, some twelve years into my career at the Palace, I had been protected, first by Biff and then by Fred, from the nastiness of the political process that led to the
distribution of the government’s money among the competing agencies of NIH and
NIMH. On occasion, Fred would trot me out during visits by congressional aides
to perform the perfunctory dog-and-pony show
with my rainbow slides of brain receptors. But other than that, I’d been left to do my science, becoming a totally
impractical, head-in-the-clouds, full-time scientist, unbothered by monetary
concerns and good only for making breakthrough discoveries. I had wandered
freely through the corridors and buildings of the Palace, becoming
multilingual, absorbing all the science, talking, listening, observing,
becoming totally lost in a fantasy-come-true of scientific heaven.
Now I was trying
to enter a whole new playing field. Clinical trials involve millions of
dollars, the futures of entire companies, the clash of many, usually male,
egos, the necessity to thread your way through the intricate maze of the FDA,
and a political sense that was entirely foreign to my direct, honest, in- your-face style. I
wasn’t even an M.D. and it’s almost always M.D.s who are at least nominally in
charge of clinical trials. In sum, I was completely unprepared to deal with the kind of real-world,
big-business wheeling and dealing that was necessary if I was going to have any
hope of having a direct impact on peoples health, just as before, when I had
been seen as invading the cancer lab director’s turf, I was trying to stray
beyond the traditional confines of my world without understanding how rigid the
turf boundaries were, and how threatened people became when anybody made a move
to cross them.
RESIGNATION
The final blow
came in June 1987 when a Harvard researcher with a private biotech company
affiliation announced during his talk at a major conference that Peptide T
could not be effective as an AIDS therapeutic and should not
he
tested.
In a perfunctory manner, he closed his talk by showing three quick slides on
Peptide T, and then explaining how he and several of his colleagues at the NIH had failed to replicate its antiviral
effect in vitro.
The effect
was like a bucket of ice water
being flung in your face just as you’re waking up from a long cozy nap.
Michael and I both snapped to attention. Failure to replicate—the scientific kiss of death!
All it took was a few brief words by an “expert” who claimed he
and his colleagues couldn’t replicate our experiment, and Peptide T was dead,
killed before it ever got out the gate. The press was at this particular
conference and grabbed on to the news for their evening headlines: “Novel AIDS Drug Bites the Dust,” read one.
“Experts Say Promising AIDS Drug Doesn’t Work,” said another.
Initially,
putting our shock and confusion aside, we decided to treat it as a collegial disagreement. First we addressed
the obvious questions: Why had no one called us up or walked the few
hundred yards across the quad to tell us about their results? And what exactly
were they finding that caused them to pronounce “a failure to replicate”? The objection, we found out, was
against our claim that Peptide T stopped the HIV virus from growing in the test
tube. But the harder we pressed, the less we understood, until it dawned on us
that maybe the experiment hadn’t been performed correctly.
When we
finally got to examine the data, we discovered that the other labs had not closely
followed our steps. They had increased the concentration of the virus by a
factor of 100,000, while keeping the concentration of Peptide T at the level we had used.
They had also used “lab-adapted” cultures of the virus, not the fresh isolate that Frank had
gotten us from blood taken directly from AIDS patients’ veins.
How could this
have happened? Was the failure-to-replicate pronouncement the result of a simple mistake rooted in
an old-paradigm blindness that made an unbiased approach impossible? Or, a more
disturbing possibility, was it a crude ploy at effectively trumping a pesky
competitor out of the race and thus eliminating a potential funding threat? Or
perhaps the Lasker controversy was still
dogging my heels. I am not prepared to say. But one thing I know for sure, the hoopla amounted
to a death sentence for the further
development of Peptide T within the Palace walls. Only
after certain of the experts’ favored approaches bombed and technology had
advanced enough to expose the limitations of many of the methods used in 1985 would the search for virus receptors and their natural
ligands be reinitiated—some ten years later. For the time being, I was going to have to confront the hard fact that in order to continue with my new-
paradigm child. I needed to look elsewhere than the United States government.
It was in the
depths of our discouragement, disgust, and disgrace that we received a very
intriguing phone call. I listened to the voice of a fast-track biotech lawyer, who
had learned of our predicament from his NIH scientist wife and had taken it
into his own hands to step in.
“Dr. Pert?” he
began. “We hear you have a miracle cure for AIDS that the government won’t
develop. Is that true?”
He went on to
give us details of a proposition that he believed would make us all wealthy. In one hand he held a
multibillionaire private investor and his group of venture capitalists. In the other hand was the Second Biggest Drug Company
on the Planet, which just happened to be shopping around for some new products to add to its AIDS line. The drug company,
of course, had tested Peptide T in its own labs, replicating our experiments
and finding our claims to be 100 percent accurate. If we would just say the word, our savior
promised, he would clasp
these two hands together in a business
handshake that would seal the deal and give us whatever we needed to develop
our drug.
IN AUGUST OF 1987, one year from the date
Gajdusek had submitted our controversial paper to PNAS, I handed in my resignation. Following the established protocol, I met my lawyer at
the entrance to Building 10 and we rode the elevator to Fred’s office suite,
where Form 52 would be finalized. In a brisk
and businesslike manner, Fred’s secretary handed the papers to Fred, who
passed them on to my lawyer, who gave them to me. By signing on the line, I was
about to end my tenure and stroll
away from the best deal in science that exists
anywhere, the chance to work at the NIH. But I didn’t hesitate for a second.
I was so determined to carry Peptide
T forward that had my dead father
appeared in a vision and pleaded with me to reconsider, I would have
ignored his wishes and walked away
without a single glance backward.

CROSSING OVER, COMING TOGETHER
SPRINGTIME
IN Washington. D.C.! The
place is afloat on pink and white cherry blossoms, the air filled with elation
as the East Coast emerges from the winter of 1995-1996—the worst
of the century. For weeks
we were all buried in mountains of snow, unable to leave
home, go to offices, carry on any semblance of normal everyday life. But this morning, the day
after Easter Sunday, I noticed the daffodils in my front yard finally
starting to open, weeks later
than usual. I am heartened, even though the
early-morning TV weather report had cast a shadow
by forecasting the outrageous possibility of more white stuff coming our way.
From my office
at Georgetown University Medical School, where I am currently a professor of
research, I place a call to the office of Dr. Wayne Jonas, newly appointed
director of the Office of Alternative Medicine (OAM) at the NIH. My purpose
is to see if I can drop by for a few moments and, in the spirit
of hope and new beginnings, pay a long-overdue visit to him. The OAM was established
four years ago by the NIH to investigate and evaluate many of the alternative
therapies and practices—including acupuncture, homeopathy, manipulative healing
techniques such as chiropractic and massage, visualization, and
biofeedback—that have become so visible over the past ten years that the
mainstream can no longer ignore them.
The creation of
the OAM is a sign that the NIH is finally catching up with the American public,
which is well aware of the benefits of alternative medicine, as shown by a
study done by David Eisenberg at Harvard. In an article he published in the January 28, 1996, issue of The new England Journal of Medicine, he showed that one out of three Americans had
used at least one unconventional therapy in the previous year, for which they
spent $13.7 billion, three-quarters of which came out of their own pockets, not
their insurers’. His study prompted a few of the smaller insurance companies to include
alternative therapies in their benefits, but the majority of insurers offer no such
coverage.
The media has also “discovered”
alternative medicine, it seems, as evidenced by a rash of articles and TV shows
on the topic, especially in the last year. An article in the Washingtonian, featuring my friend Dr. Jim
Gordon, a D.C.
psychiatrist
and adjunct professor at Georgetown, who emphasizes prayer, yoga, and juice
fasting, showcased the increasing number of local mainstream physicians who are combining alternative
treatments with more Western, allopathic approaches. The article got the attention
of quite a few people on Capitol Hill, a hopeful sign, since they hold the
purse strings to the funds for all the research done at the NIH. Still,
I wonder if all the publicity hasn’t contributed to the backlash I’ve
sensed from talking with some of my former colleagues at the Palace. Lately,
people seem afraid to discuss any possible implications their research might
have in helping to understand the mechanisms
of alternative medicine. It seems, at least from an insider’s view, that
while the public is fed glowing reports of the advances of alternative
medicine, it only grows harder for
the OAM to gain acceptance in the highly resistant mainstream environment at
the NIH.
Thus, I’m quite
surprised when the receptionist answering my call gives me the address:
Building 31 on the NIH campus. Less than a year ago the OAM office was located
off-campus, purposefully kept outside the Palace walls for fear that its very
presence might somehow taint the purity of the “real” science being done by
establishment scientists on their hallowed grounds. This new move seems a promising sign of the fledgling office’s
progress and acceptance in some quarters, and perhaps
its tiny budget, which currently constitutes less than a tenth of one percent of the NIH’s funding, could someday
be increased if acceptance grows.
There’s a
familiar chill in the air as I drive through the cherry blossom-lined streets
of Bethesda on my way to the NIH, intent on my mission, which is to do whatever
I can to help the OAM get a stronger toehold at the NIH. Specifically, I have
some ideas about how to bridge the research gap—a phrase I use to refer to the
lack of basic, data-gathering laboratory research being done on alternative
therapies. This is the missing
piece that I believe is necessary to legitimize what is now still severely marginalized.
In my capacity
as chairperson of an OAM study section on mind-body medicine, a position I had
undertaken at the behest of the previous director of the OAM. Joe Jacobs, I had had the opportunity to review many studies in the field of alternative medicine, finding
good data, some as solid as anything in the mainstream, to show that the mind
and emotions can influence immunity. The experience made me ask the serious
question: If we know thoughts and feelings can
influence disease, why aren’t we doing more expanded hard research to determine
which diseases these modalities are most applicable to, and
performing
the experiments that could lead to answers and possible cures? Guided imagery
was one of the modalities on which, to my great surprise. I had found studies
proving beyond a doubt that it could influence recovery rates for patients with cancer.
Why, then, weren’t these studies being followed
up?
Acupuncture, too,
looks very promising despite its having been dismissed because knowledge about
the points and meridians, evolved over five thousand years of empirical
medicine, do not correspond to any existing Western concepts of anatomy. But absence of proof is not
proof of absence. In my mind, meridians may be the pathways that are followed
by immune cells as they move up and down an anatomical highway,
a discovery that could be just one experiment
away. The peptide-containing skin cells, called Langerhans cells, could provide the clue, but no one has ever looked at
their distribution.
Funding
preferences determine the areas that get researched, and acupuncture simply
isn’t high on the list for research dollars, and never has been. Many
mainstream researchers still refuse to believe that acupuncture has any
validity, very much in the
same way they didn’t believe the opiate receptor existed before a
simple lab method allowed us to measure it.
I wait in a
partitioned area, early for my 1 P.M. appointment,
and read the handsome OAM brochure sitting on the coffee table. I notice that
the new phraseology is “complementary and
alternative medicine,” and that there’s been some consideration of renaming
the office OCAM in the future. I like the change. The term “alternative” is too
confrontational, implying an “us or them” mentality, as if only one can survive
and the other must die. This sort of positioning does not do well in mainstream
science as evidenced by a long history of resistance to new ideas.
In my lectures,
I sometimes drive home the point of how hard it is for new ideas to gain a hold in medicine by
recounting what happened to the Hungarian doctor Iguaz Semmelweis in the 1840s.
Practicing in an obstetrics ward in
Vienna, he noticed that the impoverished women, who were under the care of
hospital midwives, were not nearly as susceptible to fatal childbed fever its
were the wealthier women, who were cared for by doctors, and he figured out
that the discrepancy could be due to the fact that the doctors were not washing
their hands before examining the women. Since the doctors were on a
daily schedule that took them straight
from the morgue,
where they did research, to the
obstetrics ward, where they performed their examinations, their hands were
often still covered with the blood and germs of the corpses when they saw the patients
—but
no one knew of the existence of germs then. In fact, it was considered a status symbol to have your white coat decorated
with gore, showing
that you had
been
doing research and therefore were worthy of much respect! As an experiment, Semmelweis tried washing his
hands before seeing patients, with the result that his patients no longer
contracted the dreaded fever. But when he implored his colleagues to do the
same, they scoffed and laughed, paying no attention to his seemingly outrageous idea. Finally,
in 1862, in a desperate attempt to make his point, he
cut oil one of his fingers and plunged his hand into the open belly of one of
the corpses, only to develop a fever and die within a few days—or so one
version of his untimely demise would have it.
Still, nothing
changed. The world was not ready to act on Semmelweis’s observations, despite
ample evidence of their accuracy, because, without any knowledge of the
existence of germs, those observations seemed to make no sense. It wasn’t until the advent of germ
theory, based on the research of Louis Pasteur and the urgings of Joseph
Lister, that finally, in the 1880s, the reluctant doctors were forced to comply
with new rules of cleanliness and antiseptic conditions. When you consider that
such blind resistance actually costs human lives, it seems unforgivable, yet
the track record shows that such ignorance is quite the norm. As late as the 1950s, there were
still some professors teaching medical students that syphilis could be cured by giving
patients the poison arsenic, an archaic
turn-of-the-century belief that had long since gone the way of blood-letting.
But old ideas die hard, and even in the face of something as miraculous as
penicillin to treat venereal disease or as simple as washing the hands
before touching patients, new ideas meet with resistance that goes beyond all rational, logical boundaries. The
parallel in modern times could be made for alternative medicine and its
dominant theme that mind and emotions directly affect health and disease. The embracing of new
concepts need not threaten the establishment so much as move it along, to make
modern medicine better, more capable of carrying out its mission of curing
disease. Using the term “complementary” instead of “alternative” would be both
more accurate and more politic.
SNOW AND CHERRY
BLOSSOMS
Interrupting my
reverie, Wayne Jonas peers over the partition wall that sections off the
waiting area in the Office of Alternative Medicine. As he takes me into his
office, I’m instantly aware of how spacious a room it is, and how expansive the view from its generous
bank of windows—both signs that some
blessings
are flowing toward the OAM these days. Outside, the snow has started, white flurries
blanketing the cherry
trees that dot the NIH campus, their blossoms barely visible. Wayne
offers me the politically correct chamomile tea, and we begin to talk just as
the snow crescendoes to a near whiteout. I share with him that it has long been
my wish to see a program started inside the NIH that would do the basic research to put new-paradigm science on a secure footing.
Only
at the level of the bench, where the important, legitimate discoveries get
made, where the belief systems get set and the paradigm gets forged, can there be a real interface between the
traditional and basic scientist and the alternative approaches.
For example, all
kinds of practitioners, from the nurse healers who practice therapeutic touch
to the holistic chiropractors who do manipulations, tell us that they “feel” subtle
energies moving through the bodies of their patients. My own hunch is that these energy emanations get created as ligands bind with receptors in the
body, doing their intricate humming dance with each other. Now, these energies
have not been convincingly measured by objective devices, although a few
physicists have worked at devising more sensitive means of measuring quantal events. Why couldn’t the NIH fund
some research on this subject?— either
on measuring the body’s energy field, or on studying how energy healers can influence this flow, perhaps by using
their own energy to trigger receptors in a manner analogous to the way electromagnetic
energy fires neurons.
Wayne Jonas agrees with me on the necessity
for basic research
and, in a threat example of synchronicity,
relates how just the day before he had presented his idea for an intramural
research program to a gathering of NIH institute directors. This is wonderful news, and if
he can make it happen, it will be a terrific breakthrough,
because up until now, the OAM has concentrated its minuscule budget on extramural activities, programs set up
at universities to do research in alternative medicine—which means lots of people
scrambling for very few funds
at such places as the University of Maryland. An intramural program would shift the focus radically. Scientists hired by the OAM would work within the labs on the NIH
campus, the attraction being that they would
come with funded positions, which are rare at the NIH these days.
This would also
be a big step toward putting alternative medicine on a serious scientific path.
Traditionally, research is divided into two types, clinical science and basic science. Clinical
science deals mostly
with human beings
who take part in clinical trials,
where specific, very practical questions are asked: Does this drug work? Does that
manipulation work? In other words, the people are the rats. These are not easy experiments to do, costing
millions and often
involving
serious
ethical issues that can seem to get in the way of progress. By contrast, in
basic research, you’re asking different kinds of questions, ones that don’t
necessarily lead to practical results. Basic scientists never know where their
experiments are gong to lead, and they get nervous
when asked what it all means, for although they certainly
hope to make it possible for major medical breakthroughs to occur, they see
their role as the assemblers of myriads of little tiny pieces of a huge jigsaw
puzzle, which will at some vague time in the future enable the big picture to
become clear. Wayne and I share an appreciation of basic science, and we would both like to see Congress funding
the NIH to do more of that kind of work, some of which would focus on alternative medicine.
We end on this
note of agreement, and I offer to help in any way I can to get an intramural
program up and running this year.
The snow has
stopped. As I make my way to my car in the unusually chilly air, I am feeling heartened by the new
possibilities for science at the NIH. Snow and cherry blossoms, I think, as
unlikely a pair as the Palace and the alternative- medicine movement, yet here
we are, and it is a synthesis that seems to be
coming full circle, affirming that the direction I’ve been going in all
along is the right one, the one that will lead us to a more expanded, more
inclusive, more truthful science.
RISE AND FALL
In 1987 I left
the Palace, and, along with my husband Dr. Michael Ruff, embarked on a business
venture to develop our AIDS drug. Peptide T. On the day I signed the release
forms and handed in my resignation to the NIH. I took my very first limo ride
to the lawyers office. Outside Building 10. a limo was waiting. And champagne.
As we drove to his office, our lawyer got on his ear phone and called the
Second Biggest Drug Company on the Planet to let them know that the deal was
going down. A little later, he notified our private investors, who were wealthy
third-generation industrialists. The key player, a genteel multibillionaire,
was one of the major biomedical venture capitalists in the world.
Our investors
offered us a six-million-dollar deal to support the research and development of
new peptide drugs for the marketplace, research we were ideally suited to do
because of our advanced receptor technology. Peptide T itself would be in the bailiwick of a nonprofit medical research institution we called Integra.
The
Second Biggest Drug Company was responsible for setting up the phase II human
trials for Peptide T, a task we expected them to do while we developed other peptide
drugs. Or at least that’s
what we were told would
he happening.
I knew Peptide T was going to be vindicated in the clinical
trials. While still at the NIH, I had sent a sample to
Dr. Lennert Wetterberg, head of the psychiatry department of the Karolinska
Institute in Sweden. The Karolinska has a rule that the chairman of a
department can, at his prerogative, give a new drug to patients who have a fatal disease before the drug’s been tested,
Wetterberg gave Peptide T to four terminally ill men on a
compassionate basis. Brain scans showed improvement of abnormalities attributed
to AIDS, and all four had surprising rebounds in their various AIDS-related
maladies.
But what I
didn’t know was one iota about business. Michael and I suddenly found
ourselves—two people who had been shielded from having to deal with funding or budgets throughout their professional careers—sitting near the top of
a multimillion-dollar bioscience venture. It
was a reality check when our
investors took out million-dollar insurance policies in our names and
surrounded us with the various accoutrements of the private sector: competent,
chic secretaries; car phones; business cards with titles like president and
vice president; a board of directors on which we served but had no controlling
interest. We had never played in this arena, and we proceeded to make a lot of
mistakes. One of the first
had to do with our insistence on a futuristic fantasy lab, the one “nonnegotiable” item in our contract.
It was the
eighties, and the whole venture was truly a go-go, biotech research dream come
true. Topping it all off was a two-million-dollar state-of-the-art lab, which
we named Peptide Design. It took months to get the details just right: pink
walls and blue steel columns,
expensive high-tech lighting,
vaulted skylights, and rows of
purple lab benches. Marking the building was a fabulous “Peptide Design” neon
sign, made from the logo I’d designed and had executed by a local neon artist.
I had caught lab
fever when, on a trip out West, I’d visited the lab of the Seattle scientist whose experiments using
Peptide T had perfectly replicated our results, providing the positive evidence
that led the Second Biggest Drug Company
to take us on board. Inside that lab, everything was very sexy, soft beige and sophisticated, streamlined black—the opposite of how government labs are, drab, institutional,
and gray-green—and the structure itself was perched on a hill with a spectacular view of the ferries coming
and going across
the Puget Sound. Many years before, I had seen the Salk
Institute lab, located
outside
of San Diego, rising up from the beach at night like an illuminated cathedral
of science, and I knew, even then, that someday I would have a gorgeous,
inspiring lab in which to work.
To staff our
fantasy lab, we assembled a dream team, twelve brilliant, mostly young
scientists, including several smart, tough women I’d worked with at the NIH who
probably were never going to get tenure, no matter how brilliant they were.
Once the lab was
completed, we threw a big opening party, which our investors encouraged us to do, hoping to create a big splash
right outside the Palace gates and to attract some talent to the private lands
of biotechnology. I love
to plan parties, and so I was thrilled to design this one, sketching the
invitations, planning lavish decorations and food. I chose 8/8/88 as the party
date, thinking it full of significant symbolism—this repeated digit is a
Chinese indication of prosperity and also a graphic representation for
infinity. But it caused a bit of a ruffle when one investor/board member
and his lawyer had to fly back from their private island in
Maine in the middle of August. Another board
member was obviously discomfited by my rainbow-ribbon-cutting ceremony and
festive, semimystical themes—especially when I asked him to cut the rainbow
ribbon and announce: “It’s now eight seconds, eight minutes after eight on
eight, eight, eighty-eight” to begin the revelries.
As soon as we
were settled at the Peptide Design lab, our investors, figuring Peptide T
research was complete except for the trials (which were the responsibility of the drug company), began
pressuring us to come up with
another marketable product.
But we did get a chance to pull together
an important piece of Peptide T research during
this early time in the lab, giving
us a better understanding of how the HIV virus
acted in AIDS. We were now
seeing that once the virus entered the evil and was replicated by the cell’s
DNA, fragments of its viral protein envelope, gp120 were spewed into the
extracellular space and bound to a receptor or receptors on other body cells.
These gp120 fragments, by occupying the receptor sites, blocked access to the
cell by the body’s own natural peptides
the substances intended
to fit that particular receptor.
The first such natural substance we identified was VIP (vasoactive intestinal peptide,
but in recent years a number of other peptides
that use the same receptors have been identified.
With our
sensitive receptor bioassays, we could measure the gp120 in the blood of even those
people in very early stages of the disease. This finding was a clue to us that
it was the blocking of the body’s receptors by these fragments, not the infection of the cell by the virus, that caused the symptoms of AIDS! Our
neuropeptide
receptor “blocking” theory was further strengthened by an understanding of just
how the natural neuropeptide VlP functioned in the organism. First, VIP is
active in the gut, where it regulates water flux, and in the brain, where it
promotes the growth and health of neurons. When gp120 binds to receptors in the
brain and preempts VIP activity, neurons die or, equally as damaging, lose
their axons and dendrites, causing the dementia effects observed in an increasing
percentage of AIDS patients. Second, VIP is also I found in the thymus gland
and bone marrow, where it controls the maturation of lymphoeyte cells, which
are responsible for a strong and healthy immune system. The gp120 receptor occupation causes apoptosis, or programmed cell death, which is
another way of saving it shortens the normal life span of these critically important T4 lymphoeytes, resulting in an impaired
immune system and increased susceptibility to
opportunistic disease the cause of death for most people with AIDS.
This new understanding
was in direct opposition, once again, to what most other AIDS researchers believed at that time, which was that it
was the direct infection of the cell by the HIV virus that caused symptoms of
AIDS. We saw it more simply as the blockage of VIP, resulting in a failure of
neurons to grow and immune cells to mature. (The wasting effects of AIDS—weight
loss, failure to thrive—were to be
understood much later,
using our same theory, when we
proved that the gp120 also fit and blocked the receptor for the growth- stimulating hormone GHRH.)
At the same time
that we were doing this research, we were also trying to invent new drugs, which our investors were eager for us to do.
So this was a period of daily
brainstorming meetings, in which our handpicked staff of researchers would
march into the huge octagonal conference room and lay out their data for all to see. At the time,
the business of turning peptides into drugs— or finding nonpeptide analogs
called peptidomimetics—had not yet emerged.
Peptide
T came ten years before its time, and while we believed we’d produced one of
the first therapeutics to be custom-designed to the precise molecular
requirements of the organism, most researchers were nowhere near as appreciative as we
were of our new-paradigm child. Nonetheless, mimetics were our major interest,
and the first one we began to develop was a drug that stopped brain damage due
to severe head trauma or stroke. It was it hot topic then and is now, and quite
a few other large drug companies had their people working to synthesize
potential therapeutics. In patients with head trauma or stroke, the
neurotransmitter glutamate gushes
out of the neurons and, over time, kills the
cells.
If we could intervene and block specific glutamate receptors soon after the accident
or stroke, we believed victims who now die or are permanently crippled from
head trauma would be enabled to survive. Unlike the larger labs that were
trying to create a drug de novo, we were looking for the natural endogenous
peptide ligand.
I had quite a bit of familiarity with the mechanism
involved in these often
fatal conditions. Years earlier, in my lab at the NIH, Remi Quirion and I had
set the stage for the current approach
by mapping the PCP (“angel
dust”) receptor by
autoradiography in rat brains, and in collaboration with Tom O’Donohue had even
shown that its endogenous ligand was a peptide. PCP, a street drug that started
life as a promising anesthetic, had its commercial development abruptly halted when it was observed that patients coming
out of the anesthesia reacted like raving psychotics. My Bryn
Mawr classmate Suzanne Zukin, now a full professor at Albert Einstein
Medical School, had developed the first
PCPreceptor binding assay
with her then husband, Steve
Zukin. In a rare
example of old-girl networking in pharmacology (there’re just too few inthe- know old girls around). Suzanne had passed
on to me the results of the latest neurophysiological experiments, which
suggested that the receptor for PCP was the
same type of glutamate receptor that needed to be blocked to prevent further
damage from glutamate leakage in head-trauma victims. Now I had the perfect
project to launch in my own new lab! We would identify the endogenous peptide
ligand for the PCP receptor, and then synthesize it for a “natural”
therapeutic.
At the end of
fifteen months of furious work, we cracked the structure for the endogenous
ligand and took out a patent for the peptide we finally named Neuroprotectin
for treating head trauma and stroke.(Our investors had wisely nixed our lab
slang moniker, “Angel Dustin,” a term we all had jovially used during the long
nights of grinding up brains and running assays because we thought it was a
clever punning name for a drug based on the brain’s own PCP.) The long, tedious
period of laboratory research made Michael and me realize how miraculous it was
to have deduced Peptide T within just a few days—with no laboratory work, just a few intense hours at the computer.
It was right around
this happy time that the Second Biggest
Drug Company on the Planet made a sudden and unexpected executive decision to withdraw
their support of further Peptide T development. We heard that a choice had been
made, somewhere up at the top of he company pyramid, to pursue a new AZT- like
drug that was showing great promise, and because of the high cost of
shepherding a drug through the FDA regulatory procedures, the powers
that be
considered
it economically unwise to develop both drugs. Peptide T was seen as a gamble, while AZT,
the first drug shown to work against AIDS, although a highly toxic
chemotherapeutic was tried and true in the marketplace. Besides, AZT was the
darling of the best-funded NIH institutes (NCI and NIAID) that were involved in AIDS research, and this
new “son of AZT” was sure to be the same.
Within days of
the decision being handed down, Peptide Design became Peptide Demise.
Faced with the daunting prospect
of having to pay for the
further testing and development on their own, our investors wasted no time in
dropping out. Our lab was shut down, and then the NIMH took away our license to develop Peptide T. Our staff, now
numbering twenty-five people, was left without jobs (but we were able to help
each and every one of them land new positions, many at the NIH).
The only bright
spot in the general darkness was a phase I clinical trial we’d managed to get
up and running at the Fenway Clinic in Boston, funded with money we might have used to postpone the
lab’s closure by a year. A group of thirty men and women received Peptide T in
a trial to test for toxicity and improvements that lasted six months. The
results were impressive; the disappearance of some AIDS symptoms without side
effects could be well documented. When the trial was over, the Provincetown
Positives, a group of HIV-positive men
who believed in boosting their immune systems with nontoxic strategies like
diet, food supplements, and exercise, fought to gain permission for friends to
continue receiving the drug, and finally won. From that trial, mostly through the efforts of John Perry Ryan and the other Provincetown Positives, word of Peptide T’s beneficial
effects spread, and a number of national AIDS activist groups demanded to know what was going on with the successful nontoxic therapeutic Peptide T.
But they received no answers. In a burgeoning AIDS drug underground, several
small labs began to manufacture Peptide T and sell it through buyers’
clubs in New York, Dallas,
Atlanta, Washington, D.C., Los
Angeles, and San Francisco, and while it was the number-one best-seller for a couple of years, the anecdotal evidence was of no use in
furthering the drug’s commercial development.
With the
activists on our side, we fought to get back the license to develop Peptide T.
But the NIMH stubbornly held on to it. During this phase when all decisions
were going against me, I often grieved for the loss of the support of my
powerful mentors. Finally, the government restored the license to Integra, our
research institute, but in an odd and seemingly punishing move, they also gave
joint licensing rights—unprecedented then and now for any drug—to a tiny
Canadian
company that had none of the qualifications we had. What the government had done, in effect, was to insure
that we would not be able to get
any mainstream funding for further development, as no drug company with the
millions to invest would ever support research it could not own in its
entirety, for obvious reasons.
Gradually, the
magnitude of our loss began to dawn on us, along with the implications of that
loss for the AIDS community. If Peptide T was going to be developed any
further, which was now a matter of getting the FDA to approve phase II trials,
then it would have to be Michael and I alone who would make it happen. And to
do that we needed to raise more than ten million dollars. FDA approval is
granted only when a pharmaceutical company or other sponsor has invested the millions of dollars that it typically takes to put a drug through
clinical trials in this country. But with the divided license we now held, who
was going to invest?
While we
floundered, research being done in the labs of some of my professional
colleagues was supporting our claims that Peptide T was a drug worth testing. Doug
Brenneman’s work at the NIH, for example, buttressed our claims when he showed
that Peptide T could stop the death of neurons caused by gp120 blockage
in an elegant brain-culture system he used. And data from a small NIMH-funded Yale double-blind
study would have removed all remaining objections if it had been a larger
study—and if science was all that mattered. For the first time we had solid
evidence that the improvements in neuropsychological testing were caused
by Peptide T. The subjects of the Yale study
improved when they received Peptide
T, and got sicker when they
received the placebo.
The subjects in
the Yale study were given Peptide T or a placebo randomly, and then, after a short
time, were switched
over, receiving the opposite. This type of study is a phase II study for
clinical trials, whereas the Fenway Clinic study
we’d done was a phase I trial, intended to test mainly for toxicity, which
proved to be nonexistent. In fact, the lack of side effects
was also accompanied by some marked improvements,
However, in a phase I study, subjects know they are getting at least
some of the drug, and so improvements in their condition could possibly be due to their
expectations. (The placebo effect—the expectation of improvement actually
changing outcome—is an extremely powerful demonstration of the involvement of
the mind in healing. In his stunning book Timeless
Healing. Dr. Herbert Benson explores this effect thoroughly in establishing
his thesis that we are hardwired for faith.)
We wondered at
the time whether Peptide T’s lack of toxicity had become a problem for the
Second Biggest Drug Company on the Planet. Certainly they’d never before had a
noutoxic drug that was also effective. Most of their hot sellers were virtual
atom bombs, anticancer drugs that destroyed the immune system itself in an attempt
to save the patient. The idea of a nontoxic therapeutic could well have been a
complete enigma to most of their top scientists, and Peptide T wasn’t tailored
to fit their preconception of what a winning drug for such a
deadly disease should act like. In addition, no sizable phase II placebo trial
to demonstrate improvement beyond
a doubt had been carried
out, and the studies
in Boston and at USC were easy to dismiss as too small and of uncertain
validity because of probable placebo effects. The fact that survivors of the
Boston trial continuing to receive Peptide T had lived significantly longer
than other people with the same T-cell level in 1989, when the Boston trial
began, was harder to dismiss as a placebo effect. But by then no one was
listening. Peptide T was considered a joke,
or worse yet a hoax,
by the world of AIDS researchers—if
they remembered it at all.
RETREAT
Expelled from the paradise
of our Peptide Design lab, we retreated
to an office in the basement
of our home to lick our wounds and plan a strategy. Mike had thrown together a
working space made up of a few pieces of furniture we’d managed to salvage from
the lab and a jumble of assorted computer equipment we’d inherited. It was a
sorry comedown from the 10,000-square-foot showcase where we had once, briefly,
spent our days. Worst of all was the loss of all of our personnel. How could we
function without Bernice Blade? We kept our wood- burning stove
going all winter,
trying to keep warm as we phoned
and faxed every possible lead
that came our way.
Besides leaving
us labless to carry on our work, the drug company pullout had cast a shadow
over our credibility and added to our difficulties in finding new
sponsors. But we kept busy. For the next eighteen months I made the rounds to trot out my one-hour dog-and-pony act
for potential investors, contacting over fifty large multinational drug
companies and getting down on my knees (figuratively speaking) in at least a
dozen boardrooms, only to hear the same depressing response: Yes, your science
is very compelling, but why did the Second Biggest Drug Company on the Planet withdraw their support? And,
what’s this business about a split license?
But the drug company pullout and
the split license, I had to admit, weren’t the only reasons we were having such
a hard time. One problem, Michael and I felt, was that Peptide T was just too good to be believed. After labs all over the country had spent millions to try and
find the right piece of gp120 to block the virus, we reach out, see a rainbow,
and get a structure off the computer that hits
the bull’s-eye. No wonder people thought it was hoax—or
at least a blunder.
And then there
was my reputation as a firebrand, a troublemaker, which still lingered all these years
after the Lasker
controversy, making people
wonder what the “real” reasons were behind the drug company pullout that
landed us on our fannies. Potential investors could practically be heard
whispering to one another: “Pert? Wasn’t she the one who was involved in that
flap over the Lasker?”
It was a hard
thing to face, but I had to come to terms with my own responsibility for the
whole debacle. In addition to the very bad karma from the Lasker, I’d incurred
further establishment wrath by being an unquenchable spitfire when the NIH had
refused to support trials for Peptide T, and I had earned more than a few enemies by insisting that I had the
answer, the only solution that could cure the AIDS virus. Hadn’t I offended the
private investors with my quasi-spiritual antics and extravagant demands? It
was a bitter pill to swallow, but I was forced to take a long, hard look at my
behavior, my very unpolitic lack of respect and consideration for forces that
seemed to so fiercely oppose me.
As far as most
of my former colleagues at the NIH knew, the ones who were running the major research
being done at the time. Peptide T had never shown
any promise. Now they could dismiss us all the more, criticize
our work as absurd
and worthless, and point to our investors’ retreat as the supreme
evidence. For a period of time after the crash, whenever we would apply to present our data at the big conferences,
we were turned down or marginalized by only being permitted to display a poster
on the last day of the conference. At the end of a talk, we used every
opportunity to approach the microphone, because it was the only way we could
get our data across, in spite of the sniggering moderators who tried to dodge
or ignore our persistent requests. But we kept on, because at every meeting
we’d usually manage to convince a few more researchers to try the drug, run it through
their own systems,
and see what Peptide T did to block gp120. And each time they did,
following our direction or getting new data from their own systems, they were
able to replicate the results. Meanwhile, other labs were duplicating and extending our work and beginning
to
speak up and be heard, a fact that made us glad, even though we were kept from
adding our two cents.
During this
period of time, Michael and I were self-confessed business morons. We never really
understood the requirements of the business
world as we struggled valiantly but without
skill to resurrect
our research and development of Peptide T. Thelma, the
tough investment banker we had hired to find
us investors, used to lecture
me on becoming a “CEO with guts,”
looking the part by wearing my hair in a bun, dressing in blue gabardine suits, not smiling at
board meetings. And I made several attempts to assume the role in the last days
as Peptide Design slowly drained away, but Thelma, who fiercely believed in us,
was still unable to land us a new investor. Not that she didn’t try. On what
must have been one of our very last days in the lab, she called long distance
and asked that we usher everyone into the richly furnished conference room.
“Your long
nightmare is over!” Thelma’s voice crackled from the West Coast over the little box on the conference room table. Our staff perked up and gathered round, their brows
wrinkled with the stress of their secret
job-hunting. “I have landed a major pharmaceutical company to develop
Peptide T and fund your lab and other inventions for the next ten years. I am
hoping to wrap up the deal and sign the contracts shortly!”
It was
devastating when, just a few weeks later, a cruel and succinct turn- down
arrived by fax at our dining table during a psychoneuroimmunology and cancer
conference we were attending in Germany. As I read the news, tears rolled down
my cheeks and I silently struggled to maintain my composure in front of our
curious and concerned hosts. Sadly, it was a scene that would be repeated in
different settings many times over the next couple of years.
The stress of
the nearly constant disillusionment during this period was almost more than I
could bear. The loss of the lab and the dying down of the incredible wave we’d
been riding ever since leaving the Palace left us crashed upon a bleak and
empty shore, stranded and on our own. It was the winter of 1990, and all we
could do was hole up in our basement den while we made the calls and sent the
faxes we hoped would enable us to carry forth what we believed in. Nothing
seemed to be working.
Certainly I’d been through
tough times before—the period after the Lasker,
the frustrating last days at the Palace when we couldn’t make any headway in
publishing our results or getting funding for trials of Peptide T. I was no
stranger to the abuse, the shutting out, the lack of support.
But then I had been able to
deal
with it all by the sheer force of willing myself to, knocking over opponents
and making my touchdowns in spite of incredible odds. Now what I experienced
was the true nightmare, one in which all my old tactics for survival and
success were failing me, and the drama was beginning to take its toll. In a period
of just a few years, I gained
over fifty pounds, using food as a sedative to alleviate the uncomfortable negative
emotions that had arisen: the rejection, pain,
and fear.
Michael was my
saving light. As a young boy, he had been an altar boy, and because of his
unflinching devotion, with time
and service, he’d risen to the
top as chief altar boy. Now he showed the same kind of steadfastness in support
of me and the
project we believed in, always treating me like a fellow scientist he respected
and had confidence in, never acknowledging—perhaps not even to himself—just how
close to the edge we really were. At times, he seemed to have an uncanny mental
telepathy, anticipating what needed to happen next, making sure that the right
people heard the right things,
that faxes got sent, that calls
were returned and appointments confirmed. He even voluntarily took over many
house and child-care chores, which allowed me to catch a few moments to relax.
I felt very grateful for his unceasing support.
HEALING
While this was a
time of much tumult and suffering, it was also a period of immense personal growth
for me, as I stretched the limits of my new-paradigm thinking to embrace new
modalities of personal healing—physically, mentally, and emotionally.
Under the stress
of disappointment and professional exile. I realized that I had been angry
for years, harboring deep resentments that went all the way back to Sol
and the Lasker, perhaps even further back. I had to face the fact that I’d never gotten past the Lasker, and I
was still holding Sol responsible, not only for cutting me out of the prize but
for refusing to mend bridges and give me the support I needed to gain
acceptance for Peptide T. In my mind, Sol had become one of “them,” a powerful
player behind the scenes who, with his influence, did what he could to derail
my efforts, bolster my critics, and generally wreak his revenge. In the Lasker days, when I began comparing what happened to me to the losses inflicted on Rosalind
Franklin, I had only intuited that suppressing my emotions was dangerous and might lead to cancer,
but now I had amassed enough hard scientific data to convince
me that I needed to heal my emotions if I
wanted to pull through this difficult
time—alive and healthy.
Not that I hadn’t tried over the
years to make overtures to my former mentor, inviting him to parties at my
house, attempting to get together in the hope of eventually healing our
relationship. But my focus was always on getting Sol to forgive me, and while
he was always polite in his responses, inevitably there came the moment of gentle rebuff. At rare times, when our work
brought us into the same social circles. I tried to talk to him about my work
with Peptide T and gp120, but he professed not to understand any of it and changed
the subject.
When
all my efforts failed, I would console myself by writing fanciful little notes,
hand-decorated with colored hearts, in which I would express my apologies and
ask for his forgiveness. But I never sent them.
Could I blame
him for not wanting to be my friend? Hadn’t my actions caused him to lose a
shot at the Nobel? If so, how realistic was it to expect that he’d turn around
and offer me a helping hand in my time of need?
Still, I was
tormented by his shadow, and felt that without some kind of reconciliation
between us, I would forever be in his thrall and under his power, a prisoner, a
victim. For years after the Lasker incident, I went nightly to the local Y to swim laps, hoping
that the exercise would turn my anger into energy, enabling me to let it go.
But it wasn’t working.
The demise of
Peptide Design had brought much of this old feeling to the surface, and in my
desperation I was more open than ever to doing whatever would help me to heal the old wounds. It even occurred to me
that perhaps there was a link between this unresolved conflict with Sol and the
political mistakes I had made while
trying to develop
Peptide T. Had Sol become
such a bogeyman to me that I was still projecting my anger at him onto those who stood in my
way, making it hard for them to accept my ideas and offending them deeply with
my rash and sometimes confrontational, impulsive ways? Could my unhealed
emotional traumas actually be altering “reality”?
There was no
doubt I had a reputation for being a spitfire, someone who was so hellbent on her own path that other
people often felt the best thing they could do
was simply stay out of my way. For the first time, I seriously considered: Was I the
problem? If I’d behaved differently, been a good girl, and played the game
according to the rules, would Peptide T have made it to the market, saving the
lives of people who were now dead because it wasn’t available sooner?
It was in the
midst of these depressing thoughts that I got a call from Eugene Garfield, my
advocate during the Lasker days, requesting for the umpteenth time that I describe my research in a written
statement for his publication, the Citation
Classic. Garfield granted this honor to
first authors of any scientific paper cited more than a thousand times in the
literature. “Opiate receptor: demonstration in nervous tissue.” the landmark
paper Sol and I had published in 1973, had long since passed the qualifying
mark, and a behind-the-scenes account of the discoveries that led to that paper
was now long overdue. Actually, I had tried several times over the last few
years to pull something together, but what came out was always either overly apologetic or
angry and self-righteous. I knew what needed to happen in order for me to write
the Citation piece was a deep and honest release of the anger and hurt I
still earned and had been holding on to for the past twelve years.
Two events
precipitated my being able to respond to Garfield’s request with an integrity that
finally put my inner feud to rest. One was the exploration of my Christian roots, and the other was my
discovery of the healing power of dreams to
bring about a near-magical resolution.
My attraction to
the spirit and message of Christianity came to me through music. At one of my lowest points after the Peptide
lab crash. I had been walking by a local church, feeling
downhearted and nursing the usual grudges. The
sound of voices carrying a beautiful melody
drew me inside, where I found
a choir rehearsing. When I spontaneously expressed my appreciation of their
wonderful music, they invited me to join in, which I did. For several years after, I continued to sing alto in the
choir.
My family
thought I’d finally flipped. When I was growing up, religion was a more taboo
subject than sex or money. I honestly thought that Jesus Christ was a curse
word, because the only time I ever heard the name spoken was when my mother or
father smashed a finger or couldn’t pay a bill.
My parents had
come from different religions backgrounds, and had solved the dilemma of their mixed marriage by
avoiding the topic altogether. My mother was a Lithuanian/Ukrainian Jew whose own mother had been
born in Russia—the old country, as we called it—while Dad came from a long line
of Yankee Congregationalists and could trace his ancestry to John Beebe, who’d
come to Connecticut in 1647. They eloped right after World War II, sending a
telegram to Mom’s parents announcing the marriage, a missive that hit the
household like a second Pearl Harbor. In those days, a Jewish girl like my mom
marrying a non-Jew was much less tolerated than it is today, regardless of
whether the family was observant or not. Even so, the culture of Judaism held on, if the practice
did not, and my mother always considered herself Jewish at heart. I remember asking my mother when I was about ten years old what
religion
we were, and her replying. “You’re Jewish, and don’t forget it.” Having never
seen the inside of a synagogue except once when attending a cousin’s bar
mitzvah, I had absolutely no idea what being Jewish meant. Later, as a young adult, I easily embraced the atheistic
viewpoint that seemed to make the most scientific sense. It was the sixties
and Time magazine had finally joined Nietzsche in proclaiming that God
was dead, reflecting the spiritual vacuum my generation experienced. But because
the whole subject
of God, soul, and spirit had been so suppressed in my upbringing, I was fascinated by it and found
myself drawn to anything that touched on consciousness and dreams, which until
then had meant the soaring sensibility of Romantic-era poetry and literature.
It was the strong Christian tradition
on my father’s side of the family that I now embraced. Many of his people had been ministers or, like my uncle Bill, who had played the organ at our
wedding, church organists and musical directors with strong ties to the church.
Soon I was attending services at the local church, throwing myself into the
hymns and verses, trying to absorb the Christian ethic. I felt deeply moved by Jesus’s message
of compassion and forgiveness, knowing it spoke directly to what I needed
to hear. Often, while I sang in the choir, tears would stream down my face for no apparent
reason. I now understand that what
I had found in the church, in the choir, in the music I was singing was a safe haven, a tremendous opportunity to heal my
emotions. I could let go, finally, taking
off the armor that I’d kept in place for years.
The Christian
experience was the first step toward a resolution of my inner conflicts;
interpreting my dreams was the second. I have believed in the importance of
dreams ever since as a teenager I read Freud’s Interpretation of Dreams, and began to pay attention to these
messages from my subconscious. While I never dreamed about Sol, I did have one
pivotal dream that was as clear as daylight and actually led directly to the
step that allowed me to achieve forgiveness—at least in my feeling toward Sol,
if not his toward me. In the dream,
which was set in a Wizard of Oz movie,
I, instead of Dorothy, threw a bucket of water on a witchy Sol, who shriveled up, shrieking, “I’m shrinking, I’m shrinking,” just like
in the movie, until he disappeared. What I realized on awaking was that I had given Sol his power over me, I had made him into a monster, the
enemy, to the degree that his very existence tortured me beyond anything he may
or may not have done to me.
I immediately
wrote him a letter, one different from the little-girl letters I’d written but
never sent. In this letter, I told Sol I forgave him and asked him to forgive
me, making it very clear that I expected no response, no
acknowledgment
of my request. The slate was wiped clear, I told him, and that was how I truly felt. By doing this, I
experienced a deep acceptance of the situation, a level of personal
responsibility that led to a profound emotional healing. All these years
I had been stuck in a figment
of my own imagination,
and, now, realizing this, I was becoming free. I learned that I could forgive
regardless of whether the person I believed had harmed me acknowledged the
forgiveness. It was something that happened inside
me and didn’t need to happen inside Sol. And although I have
to admit I have temporary relapses in my absolution, and I’m not ascending to
total sainthood as of yet, this act of forgiveness was a breakthrough that
freed up tremendous energy for me to continue
in my work and pursue my truth.
DEALING WITH STRESS
It was in 1991,
at an all-time low in our Peptide T campaign, that I found myself in Boston speaking
at a conference sponsored by Interface on the future of medicine. Interlace was a
forward-looking organization whose purpose it was to explore the ground where psychology and spirituality meet,
and they had gathered several cutting-edge medical people to address this
subject. After my talk, I joined a
panel of the speakers, one of whom was Dr. Deepak Chopra, who at the time was just beginning to become
well known for writing books that updated the ancient Indian Ayurvedic
tradition for the Western mind. I had missed his talk, but was impressed with his
responses to questions from the audience. He seemed to have an answer for
everything. Perhaps that was what inspired me to ask a question of my own as
the panel session was ending and the audience beginning to thin.
“Deepak, I don’t know what’s going on. I have a brilliant drug that can
save people’s lives. I’ve been working on it for years, and I can’t get it out
the gate. What am I doing wrong?”
He listened carefully and then, gazing calmly and deeply into my eyes,
gave me a stunning answer: “You are trying too hard!” he said and then smiled.
I took this in for a moment and then responded.
“Trying too
hard? But I’ve never heard of such a thing!” I exclaimed, incredulous that he
would make such a suggestion. In the world I lived in, there was no such thing
as “trying too hard.” In fact, my whole life had been about trying hard enough,
striving, ever striving
to be the best at whatever I did, in
spite
of all the obstacles. The dual legacy from my parents—the Protestant work ethic
and the fierce New York Jewish competitiveness—had driven me to graduate at the top of my high school
class, to enter and succeed in the Ivy League
college halls, and to plunge ahead, however ill-advisedly at times, in my
journey to the very pinnacle of my profession. The idea of “trying too hard”
was a concept as
foreign to me as UFOs being real. I was genuinely mystified, and had absolutely no idea what he was getting
at.
“Please, be my
guest,” I next heard him say, “and come to my health center in Lancaster, where
I’d like to show you a few things.” The idea that he had something to show me
that might somehow lead to the acceptance of Peptide T was enough to get me
packing. I accepted on the spot with a promise to make immediate arrangements,
while what was left of the audience, which I’d completely forgotten about but
which had been witness to the entire exchange, gave us an approving round of
applause.
Within a few
short weeks. I joined Deepak at the Maharishi Health Center in Lancaster,
Massachusetts, where he was then medical director, and took up residence in the
Barbra Streisand suite. I was fed elegantly exotic, tasty, vegetarian fare, and
treated to a daily massage, complete with sesame oil being dripped slowly and
luxuriously onto my forehead. The whole experience was utterly unlike anything
I’d ever been exposed to.
A visiting
Indian physician in full rishi garb visited me daily. “Fennel, she needs lots
of fennel.” he seemed to be saying beneath his breath after an examination that consisted of holding my wrist for a few seconds and reading
my three Ayurvedic pulses in an extraordinarily mystical bedside manner that all
the staff members seemed to have absorbed in their training.
But the most
amazing benefits began when I was taught how to meditate, the heart of the
healing methods offered at the Health Center. Deepak had a staff member teach
me TM (transcendental meditation), a form of Indian meditation that had been
packaged for the Western mind, and a method I knew about because the Beatles had taken it up in 1968. I remember
thinking, If the Beatles did it, its probably okay for me! (A longtime Beatles
fan, I can still amaze my fourteen-year-old son Brandon by being able to sing
every word of certain cuts off the White Album.) I easily learned the
simple TM technique, which consists of a mantra, or Hindu sacred word, to be repeated
over and over for twenty minutes, two times a day, and brought it home with me,
and I’ve continued to practice it daily. In my quieter mental state, I could
experience how events were unfolding quite naturally around me, without
my having to make them happen.
I also started
to become aware of synchronicity, to see connections between events and people
happening simultaneously and then to act on this awareness instead of out of
the more familiar linear cause-and-effect model. I had encountered the theory
of synchronicity years ago in the work of Carl Jung, where it is defined as “the coincidence of events in space and
time as meaning something more than mere chance.” And while I didn’t quite
understand it then, it appealed to me
intuitively. Now I understand that, as in the psychosomatic network, related
events occur simultaneously in time and space, in spite of our perception of
them as unconnected and independent. This allowed me to trust that life would unfold
without me as the prime mover, the brain always leading the way!
When I first began
meditating, I was besieged by visions of my father lying helpless and dying on
his hospital bed, hooked up to IVs and devices, the paraphernalia of his
Western medical “saviors.” Other emotionally charged visions, some from childhood, seemed to percolate up into my
conscious awareness as I continued
meditating, as if these thoughts and feelings had been packed away in storage
somewhere, waiting for me to stop everything, sit quietly and relax with a
focused mind long enough to allow them to arise.
I marveled at
this process and attempted to understand it in terms of physiology. I was
especially interested in how meditation’s effects on stress had an impact on immunity, and what this meant
in terms of the brain-body connection
I had seen in my laboratory research. At the time, I had read The Relaxation Response, Herbert
Benson’s first book written in the seventies, in which he attributed meditations power to an alteration of the nervous
system from sympathetic to parasympathetic pathways. But with my knowledge
of the bodywide psychosomatic network, I was beginning to think of
disease-related stress in terms of an information overload, a condition in
which the mind-body network is so taxed by unprocessed sensory input in the
form of suppressed trauma or undigested
emotions that it has become bogged down and cannot flow freely, sometimes even working against
itself, at cross-purposes. In the
late fifties, when it was shown that tumors transplanted into rats placed in
stressful situations grew more rapidly, we used to attribute stress-related
disease to increased levels of steroids that acted to suppress the immune
system. But our new understanding of
neuropeptides and receptors has enabled us to see more of what is going on in
conditions of stress. When stress prevents the molecules of emotion from
flowing freely where needed, the largely autonomic processes that are regulated
by peptide flow, such as breathing, blood flow, immunity,
digestion,
and elimination, collapse down to a few simple feedback loops and upset the normal healing response.
Meditation, by allowing long-buried thoughts and feelings to surface, is a way
of getting the peptides flowing again, returning the body, and the emotions, to health.
I came to think
of my first experiences of meditation as experiments— experiments in the
release of highly charged emotional memories that had been stored somewhere
within the psychosomatic network. Since the only lab I had access to at the
time was that of my own mind and body, I paid careful attention to these early experiments, and later
found that my thoughts about what I was experiencing correlated with research
that my colleagues were doing on how trauma and blockage of emotional and
physical information can be stored indefinitely at the cellular level.
In addition to
meditation, I was making practical, everyday changes in my lifestyle, getting
regular massages, eating a healthier diet, doing more exercise.
At this time, I also switched from relying strictly on allopathic, or Western,
medicine. Having read an article about chiropractic, a onetime sizable and
respectable branch of mainstream medicine that had been discredited by the drug
and surgery branch, I couldn’t help identifying with chiropractors as fellow
underdogs, victims of what we call
modern medicine. And then I met one!
The very day
after reading the article, I was in a health-food store stocking up on fresh
veggies when I thought I overheard a handsome young man say that he was a
chiropractor. I got his attention and began a conversation, learning that he
had a practice in town and often treated people
who were dealing
with stresses on the scale I
was. But the odd thing was that he insisted he’d never mentioned that he was a chiropractor, and I
must have been telepathic to think he
was!
When
I went to his office for an appointment the next day and filled out the
standard forms, I wrote in the section asking who had referred me: “God in the
form of synchronicity.” I became a regular at the office of Dr. Joseph Skinner,
who introduced me to the power of chiropractic and who later became a close
family friend.
Another of my
early health “gurus” was Carolyn Stearns, a massage therapist recommended to me
by a broad-minded M.D. who was treating me for a rib injury I’d sustained during a bike tour. Carolyn,
who had been a professional dancer, writer, and poet, was now doing a form of
“psychic” massage that she’d developed from her own intuitions and spiritual
awareness. She put her hands on various parts of my body and “read” that even though I had spent my life in a left-brain profession as an analytical,
rational scientist. I was an extremely
spiritual,
intuitive person. This part of me, she said, had been buried, shut down since
childhood, and I instantly recognized the truth of what she was telling me. She
was referring to that quiet inner voice that had been speaking to me for years, the one that had led to some of the biggest breakthroughs in my work.
Now,
with Carolyn’s support and confirmation. I began to trust more and more in my inner voice, both personally and in
my work.
I lost contact
with Carolyn for a few years, but when I reconnected, she had moved on from
doing psychic massage to teaching stretching, visualization, and therapeutic
movement.
“What I do now
is more powerful because I teach you to do it yourself,” she told me
on the phone when I called
her. I began attending her classes regularly and greatly benefited from a series of
deep stretches using an assortment of balls and props, a kind of
“do-it-yourself” chiropractic that probably rearranged the peptidergic nerve
bundles lying alongside the spine. Once we were stretched, she’d guide us through a soothing,
rhythmic movement set to evocative music, allowing emotions to percolate up and
be released into consciousness. As we lay on
the floor deeply relaxed. Carolyn would read an inspired meditation or guided
visualization to help us become more deeply aware of our emotions. One day she
read us these words, which
hit home in a very direct wax: “If you look
underneath your depression, you’ll find anger.
Look under your anger, and you’ll find sadness. And under
sadness is the root of it all, what’s really masquerading all the while—fear.”
I had
experienced all of these emotions in my personal and professional journey, and
now, as I struggled to deal with my stress and survive the rough times. I was
beginning to understand Deepak’s words. Finally, I was learning to stop trying
so hard. It was through my experience with Carolyn, the meditation I learned to do, the many
healers and alternative practitioners, open-minded M.D.S, massage therapists, and
chiropractors I encountered that I moved closer and closer to what is my
current, essentially spiritual outlook on life.
A NEW CROWD
During this period
of labless existence, I increasingly accepted invitations to speak at
conferences and meetings that convened for what I called the new- paradigm
crowd—the practitioners and theorists, as well as the recipients, of
alternative healing modalities. Though many of these modalities had a basis in
Eastern philosophy and other non-Western traditions, which as a Western- trained scientist I would not
ordinarily have known anything about, I had in fact had a limited exposure
to Eastern ideas that dated back to the mid-eighties during my NIH lab days.
Because of the growing public awareness of my research on endorphins and other neuropeptides,
people from all kinds of unexpected backgrounds
had sought me out at the time. A bearded yogi dressed in white
and wearing a turban showed up at my office one day to ask me if endorphins
were concentrated along the spine in a way that corresponded to the Hindu chakras. The chakras, he explained, were
centers of “subtle energy” that governed basic physical and metaphysical
functions from sexuality to higher consciousness. I had no idea what he was talking about, but, trying to be helpful,
I pulled out a diagram that depicted how there were two chains of nerve bundles
located on either side of the spinal cord, each rich with many of the
information- carrying peptides. He placed his own chakra map over my drawing
and together we saw how the two systems overlapped.
It was the first
time I seriously considered that there might be a connection between my work
and the Eastern viewpoint. Before he left, the yogi taught me some simple exercises
for focusing attention at each of the chakra levels, which I experimented with
and found highly enjoyable for the energizing effects they produced.
It was soon
after that encounter that I experienced a whirlwind, California- style immersion in mind-body ideas when I spoke at an April 1984 symposium at Stanford University,
sponsored by Eileen Rockefeller through the Institution for the Advancement of Health, on the theme
“Can Positive Emotions Affect Disease?” I arrived at the event to find white-turbaned
yogis mingling with buttoned-down medical researchers, one of my first glimpses
into the new convergence of the Western, material viewpoint and the more
Eastern, spiritual one (not to mention the convergence of the East and West
coasts!). It was there that I began meeting people who had written and spoken on the interface between health and the mind, including Norman Cousins, whose book Anatomy
of an Illness I had read not long before. As I listened to the various
alternative theories and viewpoints on how emotions could modulate healing, I
realized that back in my lab at Bethesda, I had been doing the science that
explained many of the ideas that these Californians were exploring. Ideas that
were familiar to them as ancient healing
systems of the East were new to me, and they loved
hearing me provide a scientific basis for what they had been experiencing and intuiting for
some time.
When I arrived
back home, the many bird eggs that had been precariously perched in nests on my
front porch had all hatched, and the yard was filled with tiny, chirping
offspring, eager and hungry for new life. It was a perfect reflection of how I felt:
Ideas that had been gestating
in my mind for years
were now taking shape, asking
to be born. I seriously began to put my science to work on discovering the
possible molecular mechanisms of mind-body healing. But I didn’t talk much about the ideas
underlying my work with my fellow scientists (except for Michael and a few
other like-minded colleagues), because they seemed too far out.
I “came out” on
the East Coast in 1985, when an aide from the office of Senator Claiborne Pell
knocked on my lab door to invite me to give the keynote address at a symposium
cosponsored by his office and the Institute of Noetic Sciences. The theme, “Does Consciousness Survive Death?” made me hesitate, so afraid was I of sounding unscientific
on my home turf, but the fat honorarium prompted a swift decision, and I
accepted on the spot. Going public on the East Coast was a major breakthrough,
forcing me to bring my theories out of the closet.
As a result of the noetic-sciences symposium, my popularity soared. It was my first science lecture to a mainly
lay audience, and the first time I had let go of all my inhibitions about the
philosophic and metaphysical implications of my work. The audio-taped presentation was edited
and translated into written form by Harris Dientsfrey, appearing
first in Advances as “The Wisdom of
the Receptors: Neuropeptides, the Emotions and Bodymind” in 1986. A more technical presentation of this information
had previously made its way into the Journal of Immunology as “Neuropeptides and Their Receptors: A Psychosomatic Network” in 1985. Because these papers were
widely read by holistic and alternative practitioners, as well as by some more
forward-thinking scientists and doctors,
in the years that followed
I began to receive more and
more invitations to speak, many of them out West—in Los Angeles, San Francisco, Boulder, Seattle, even at
Esalen at Big Sur.
By 1991, when I
met Deepak, I had become a regular on the circuit, earning a reputation for
myself as the “bodymind” scientist, meeting and benefiting from the thinking of such Western shamans as
Stanley Krippner, Ernest Rossi, Stan Grof, Willis Harman, Fritjof Capra,
Beverly Rubik, John Upledger, and Joan Borysenko. It was a stretch for my
scientist mind to be open to their astounding theories and practices, but
somehow I found myself able to straddle both worlds as I worked to integrate the best from each.
The ability to accept very diametrically opposite points of view is due, I
believe,
to the fact that I’m a woman. Because women have a thicker corpus callosum—the bundle of nerves that bridges
the left and right brain hemispheres
—they
are able to switch back and forth from the rational, or left brain, to the
intuitive, or right brain, with relative ease. With fewer nerves connecting the
hemispheres, men tend to be more focused in one hemisphere or
the other.
A high point in
my speaking career occurred in 1991 when I spoke at the American Association of Holistic Medicine in Seattle.
Arriving late for my talk, I was greeted by the smiling faces
and open arms of many people I had heard of but not yet met, such as Jeanne
Achterberg and Bernie Siegel. This instant and genuine acceptance of me and my
work was in sharp contrast to the reception Michael and I got when we attended
the many AIDS conferences, trying to win acceptance of Peptide T, and it made
me feel totally at home with the new- paradigm crowd—as comfortable as I did with
my more establishment friends and
colleagues (as long as Peptide T wasn’t the subject). The Seattle conference
marked what I consider my personal merging of mainstream East Coast science and
alternative California “healing” realms—and thanks to my generously endowed corpus
callosum, I’ve been able to maintain an equal footing
in both.
RESCUE
It was through a
connection I made on the new-paradigm lecture circuit that a new investor for
Peptide T was finally found.
I met Eckart
Wintzen at a conference on “Medicine of the Future” in Garmisch,
Germany, in late 1990. He had come to hear me audition
as a potential speaker for his
own conference, one he sponsored annually, to which captains of industry from all over Europe were invited. The current theme he
was working on was simply “brains,” and he’d been receiving pressure from
people in his organization to add some women speakers to his conference roster. A fabulously wealthy Dutch businessman who
had made his fortune in computer software and now altruistically supported any
number of advanced global
projects, Eckart was a tall, slim man in his fifties, who wore his graying hair long and sported John Lennon glasses
on his nose. After months of dealing with the corporate suits, I found him a
breath of fresh air as well as an intriguing novelty—a rich, sophisticated
European counterculture entrepreneur.
One of my two
talks had focused on Peptide T, and afterward, over a lunch he’d invited
me to, Eckart seemed especially interested in the progress of the
drug and what its present commercial status was.
“Oh, it’s fine,”
I lied, “We’ve got a great possibility coming up, a Japanese company that’s
about to come on line.”
I just couldn’t bring myself
to reveal how bad things
actually were. But the truth was that we were at the end of a long string of
potential deals that hadn’t gone through, and our Japanese interest was looking
dimmer every day. I mentioned to Eckart that we had a deadline in a few months:
We needed to come up with an investor that could prove it had the millions needed
to bring the drug to market, or else the NIH Office
of Technology would take the Peptide T license away from us again,
perhaps permanently consigning the drug to the limbo in which it had been languishing.
We finished
lunch and strolled
casually toward the restaurant exit.
“What’s the date of your
deadline?” he asked as he reached forward to open the restaurant door.
“April 4,” I
replied, and as we passed through the open door, he looked directly at me and
said in an offhand way: “Well, give me a call if you need anything.”
Eventually I did
speak at his conference, but before that came to pass, our Japanese investor
fizzled and the deadline was upon us. Michael and I literally had reached the
end of the line, all hopes gone and all leads dead or dying. We were facing
bankruptcy, and even the loss of the house we’d bought when we were riding high
with Peptide Design. There had never been a gloomier hour. It was 9:30, the
morning of the government deadline, when the phone in our basement office rang.
“Hi, this is
Eckart,” a cheery voice said. My heart did a flip-flop. “How are you? Today’s
the day, isn’t it, the deadline you told me you had for your drug? Did you find
your company?”
“No,”
I said. “As a matter of fact, we haven’t.” There was a pregnant pause. “Well then,” he said, “tell me how much you need, and who my banker needs
to notify that I have it.”
With a simple
fax that Eckart sent directly from his office in Holland, the government got
what they needed, proof that Peptide T now had a major investor, one who could
without a doubt supply the millions needed to support further research and
development and successfully bring the drug to the marketplace.
We were back in business. True to Deepak’s diagnosis of my problem, the
solution had come only when I had stopped trying, for I had never gone after
Eckart as an investor.
12 HEALING
FEELING
THE MOUNTAINS of Southern California are spectacular in May, vibrantly green from the winter rainfall
and dotted with bursts of colorful wildflowers and shrubs. My friend Nancy’s
trusty Volvo carries us up the steep and winding San Marcos Pass as we leave
Santa Barbara and head for the Santa Ynez Valley.
From
the window, I look down the canyons to the coastal floor as we ascend, a
dizzying sight of tiny houses and crisscrossing roads. The big, blue Pacific spreads
out toward the horizon, where I can make out a spattering of distant, hazy
islands floating on its surface. It’s 1996 and we are on our way to an
appointment with Dr. Robert Gottesman, an internist and alternative
practitioner whose specialty is women’s health.
How I love
California! It’s not just the stunning physical beanty but the style, the
attitude, the healthfulness of the place. The pull that California exerts on me
was recently put into focus by a note I received from Willis Harman,
an electrical engineer/philosopher, known for his consciousness movement leadership at Stanford Research Institute and the Institute of Noetic Sciences.
His
note, in the form of a personal inscription written on the flyleaf of his book Global Mind Change, said that I was one
of the few people he knew to have both an East Coast and a West Coast personality depending on where my physical
body happened to be located
at the time! (Willis’s book articulates what I
believe to be the pivotal concept shaping the California movement, which is
that consciousness creates reality, mind becomes matter, our thoughts precede
our physical bodies, not vice versa. For many Asian thinkers this is a basic assumption, but for most Western
Hemisphere types, it is an utterly foreign, revolutionary idea.)
As the car climbs
steadily up the pass, I don’t even try to contain my feelings of exuberance, thoroughly enjoying the
moment and the rush of endorphins coursing through my blood. This is a trip
that combines pleasure with business, although the two seem increasingly merged
as of late. I am visiting first with my friend from childhood Nancy Marriott,
and then plan to hop a plane to Anaheim, where
I will present a talk at a conference playfully
entitled “Medicine, Miracles, Music, and Mirth” at—how appropriately!—the Disneyland Hotel.
Once
again the token scientist, I’ll be joining a roster of familiar alternative-
health presenters, among
whom will be my dear friend Carl Simonton, an
oncologist
who was one of the movement’s earliest pioneers in his use of visualization,
art therapy, and meditation to increase survival rates for cancer patients.
I’ve lost track
of the number of times I’ve crossed the land to the tar shore of California to
speak at alternative-health conferences, meetings, and symposia, since the very
first time, back in 1984. when I addressed the Institute for the Advancement of
Health at Stanford University. Since that initiation into the holistic crowd, I
have come to think of California as the vanguard in mindbody exploration, a
place where Asian influences intermingle with the Western tradition, creating
an easy acceptance of ideas that, for a long time, barely saw the light of day back on the East Coast.
Here in California
there seems to be room tor a consideration of the spiritual dimension of
health, which can encompass such elements as prayer, energy flow, distant
healing, and psychic phenomena, to name but a few. To me this seems absolutely the furthest edge to which
my mind can go, but for many Californians, these are long-familiar
ideas, dating back thirty years to the early
days of Esalen in Big Sur, where Michael Murphy and his friends kicked
things off.
Nancy has been
my friend since elementary school, when her mother was my Brownie Scout leader, and we’ve remained
close friends ever since. We were
two girls who grew up together on Long Island, went to the same high school,
came home to the same town during college years, and had the same dreams and
apprehensions about the future. While I stayed
on the East Coast, she headed
west as soon as she’d finished graduate school at Columbia University landing
in San Francisco and becoming increasingly involved in the health and consciousness movement
of the mid-seventies. Over the years, I made it a point to look her up whenever my lecture
schedule brought me to San Francisco or, lately, to Southern California, where
she now lives in Santa Barbara. Whenever we’d get together, we’d so often find
that our lives had followed a parallel course—we gave birth to daughters a year apart,
remarried around the same
time, and kept converging on the same ideas at the same time—that we continued to feel an easy bond, a
trusting resonance, regardless of the space and time that separated us. In
fact, just knowing Nancy was living out West was comforting to me, especially during the ten-year
period when I was crossing over from my establishment
mentality to the more expansive “Californoid thinking.”
As we drive and
talk we love to flash back on times when our paths intersected at pivotal points in our lives, often reflecting complementary stages
in
our personal growth. One of these times occurred in 1979, when Nancy was
traveling with a few friends
to New York and looked me up on her way through
D.C. I was then in the midst of my post-Lasker trials and tribulations, and feeling very fragile, so Nancy offered to teach me what she
called an “invocation for psychic protection.” a ritual she’d learned from a
spiritual teacher in California. It sounded hocus-focus-y to me, to call on higher powers to protect me from evil, but on some
intuitive level I sensed it might be helpful, and I certainly needed all the
help I could get. At the Palace the next day, I recited the words she’d given me behind my closed office
door, and immediately felt a sense of
relief from the anxiety and tension I had been experiencing.
I continued to
use the verses, especially at times when I felt particularly maligned and
unsupported, gaining strength if only, I told myself, because of the
psychological buffer they provided. But I now know that this odd ritual was a
powerful form of prayer, and I can only surmise that it acted through some form of “extracorporeal peptide
reaching,” a form of emotional resonance that
happens when receptors are vibrating together in seemingly separate
systems.
This
was before the term subtle energy had
been introduced to describe a still mysterious fifth force beyond the four
conventional forces of physics— electromagnetic energy gravity, and weak and
strong nuclear forces—to scientifically explain anomalies such as the power of
love. In this and in many other ways. Nancy was my pathfinder, introducing me
to mystic and spiritual ideas that I then sought to understand within the
context of my science.
NATURAL HORMONES
The rocky slopes
and winding road soon give way to a panoramic vista of mountain caps dusted with snow and gently rolling,
cow-studded fields. We have entered the Santa Ynez Valley and
are rapidly approaching the tiny town of Ballard, where Robert Gottesman lives and practices
medicine. Our visit
has been prompted by the fact that as front-running members of the
baby-boomer generation—we were both born in 1946—Nancy and I are now at an age
to be making decisions about the latest hormone replacement therapies being offered up for menopause. With our female
hormones on the wane, the question is whether to suddenly let nature take its course,
when our recent
ability to have sex
without getting pregnant
is not natural. A year earlier, Nancy
had sent me a
privately
published book, Natural Progesterone,
by Dr. John Lee, a Northern California physician/chemist whose pioneering work
on natural hormone substances offers an alternative to the controversial,
pharmaceutically manufactured hormone therapies such as Premarin, which are
patented analogs of estrogen. As
large numbers of our populous generation enter menopause, these drugs are selling in vast
quantities. Premarin, for example, has jumped to the top of the charts in my
hometown of Potomac. Maryland, replacing even Valium and Librium as the
bestselling prescription drug. In fact, it is one of the top five most
prescribed drugs in the United States.
Given that
hormone replacement therapy is known to be associated with serious increases in breast cancer, and
may pose other risks as well, this trend is disturbing. Why aren’t doctors
making available the natural, plant-derived forms of estrogen and progesterone, substances that are known to have fewer side effects than their laboratory-produced analogs? The answer reflects the economics of medicine: Since the
natural substances are not patentable, there is no incentive
for drug companies to study
their benefits, and so the
vast majority of M.D.S, who get their information about drugs from the drug
companies, don’t even know about
them! Having heard
that Gottesman had become a proponent
of natural hormone treatment, following
the lead of Dr. John Lee here in
Southern California, Nancy has decided that this was the doctor we should be consulting.
WHEN WE arrive, Bob and his wife, Susan,
greet us warmly and invite us into their small but stylish redwood-and-glass
home. Buddhas and Japanese water sculptures accent the modest space, providing
a tranquil, natural setting, an East- meets-West flavor I rarely
encounter back where I come from. Bob is a strikingly handsome man and, as I soon
find out, another front-running baby- boomer like Nancy and me. His tall, slim
build and sparkling blue exes are offset by a shock of white
hair, making him a study in contrast
to his small-boned,
dark-haired
wile. Susan is a nurse and professional counselor who often works with her
husband in their specialty treating women with menopausal disorders. They are
both familiar with my work, having seen me interviewed by Bill Movers on the PBS special The Healing Mind, first aired in 1992.
and make me feel as welcome as a member of their family.
Within minutes
we find our common ground, which is an interest in mindbody medicine and its
confluence with Eastern philosophy. But before we get too deeply into our
conversation. Bob suggests we do the medical consultations first, after which we can reconvene in the living room for a talk
and
tea. We agree and Susan shows me to an office, where I am pleasantly surprised
by the comfortable furniture and given plants and by the absence of antiseptic
smells, instruments, and dressing gowns. Bob joins us and begins an extensive
consultation consisting of a lengthy question-and-answer session about my current
and past state of health.
Although he is now in official doctor mode,
he maintains the same warm, social demeanor he displayed when he first greeted
us, listening thoughtfully to my answers and expressing a refreshing empathy and sensitivity. In a noticeable
contrast to the procedures followed by more mainstream M.D.S, a large
part of his professional assessment centers around my input about not only my physical
status, but my emotional state as well.
After
the consultation, he recommends a variety of hormone and blood tests to check my
existing levels of progesterone and estrogen—the two key hormones that are
affected by the approach of menopause—and another consultation by phone once
the results are in.
Bob gives me a
jar of topical cream containing progesterone made from the wild Mexican yam,
which I am to apply after the test results indicate what dosages would be
appropriate. He explains that while both progesterone and estrogen start to
fall oil during menopause—in fact progesterone decreases for several years
before menopause (perimenopause), because ovulation becomes very irregular
during those years, and progesterone is released only after ovulation—many
menopausal and perimenopausal women have an estrogen- dominant condition. This
occurs because of a lack of sufficient progesterone to “oppose” the estrogen.
Unopposed estrogen, Bob says, is the agent responsible for many of the symptoms
of menopause: hot flashes, fibrocystic “lumpy” breasts, weight gain, and fluid
retention. The topical progesterone he is giving me will lie absorbed through
my skin to protect
me against these symptoms.
Since
progesterone is the “mother hormone.” creating feelings of calm and nurturance
(especially in pregnant and lactating women, who produce particularly high quantities of it), the cream may also alleviate
the mood strains suffered by many women who are menopausal.
INFORMATION
Once our
consultations are complete, Nancy and I find ourselves back in the cozy living
room, where we are soon deep into a stimulating conversation about mindbody
medicine. Eastern philosophy, information theory, and quantum physics. I am amazed to learn that Bob is the grandson of Karl Menninger
of the
Menninger
Foundation, the forward-looking psychiatric clinic and teaching hospital in
Kansas that supported work by biofeedback researchers Elmer and Alyce Green back in the 1970s. Gottesman is truly one of the new breed, an
M.D.
with one foot firmly planted in the Western tradition and the other stepping
into the realm of alternative and Eastern traditions. And for him, its all part
of a family heritage.
Bob likes to philosophize.
“It seems to me
that the way to heal the split between body and mind is to change metaphors.”
he suggests.
Metaphors? I am
interested but wonder if we’re going to be talking about poetry or science. It
soon becomes apparent that he’s combining the two in a unique and enlightening
way that promises to offer clues to questions I’ve been thinking about for
quite some time. A metaphor, after all, is just a way of looking at things, and could just as well be called a viewpoint
or even a paradigm.
He continues:
“The metaphor I propose to understand the mindbody question is one that uses information theory, a
well-developed held with verifiable laws and
theories that are very applicable to traditional sciences as well as to
business and the humanities.”
Now he has my attention. I myself have been theorizing for some time about
a new mindbody biology, in which information is the bridge between mind and
matter, psyche and soma. When Michael and I did our original research showing
the link among immune, endocrine, and nervous systems we chose words like network, nodal point, and information molecules in order to make
the point that information-processing is what this system is all about, and we
had later adopted Francis Schmitt’s term information
substances to refer to our neuropeptides and their receptors. So this is
language that I understand.
“But first. I
believe we have to make a distinction between the metaphor of matter and energy
and that of information,” Gottesman continues. “The older metaphor deals with
matter, force, energy, and is expressed in Einstein’s famous formula connecting
those elements, E=mc2. While these terms are useful for building locomotives
and bridges, even atomic bombs, they are not so useful for understanding the
human body, physical processes aren’t things,
they are dynamic· and take place in
an open, fluid system, and therefore fit better with the metaphor of
information than that of matter and force.”
I’m beginning to
understand what Gottesman is getting at. The older metaphor clearly belongs to what is still the reigning paradigm, a mechanical,
deterministic
view based on Newtonian physics. It was rigid rather than fluid, even macho in
its reliance on force and control to accomplish goals, and could never apply to
the nonhierarchical web of relationships that make up the biological systems in
what we are calling the psychosomatic network—an altogether more feminine
model.
Bob summarizes:
“A generation ago, it was thought that the concept of matter and energy
was the basis
for understanding all phenomena. Today,
the concept of information is
replacing energy and matter as the common denominator for understanding all
biological life and even environmental processes.”
“Yes, and the neuropeptides
and receptors,” I say with new insight, “the biochemicals we call information
molecules, they are using a coded language to communicate via a mindbody
network. They are in the process of information exchange, having a two-way
conversation—very different from what happens when there is a one-way push from
behind, the way force works.”
“Yes, and that
brings me to another law of information theory,” Bob continues, “which is that
information transcends time and space, placing it beyond the confining limits
of matter and energy.”
We all look at him a little puzzled.
“To understand
that,” he explains, “let’s backtrack and understand how Gregory Bateson defined information as ‘the difference that
makes a difference.’ We all perceive the world by observing differences in our
sensory fields, such as varieties of taste,
texture, color, etc. For
instance, a cow grazing in a meadow and a botanist strolling through
the same meadow will both perceive the green grass as something that stands out from, say, the sky. But for a cow the grass will mean food, and for the botanist
it will mean a possible sample to take home and study in the lab. The difference that makes a difference, then,
is the difference to the observer. This is a very important concept in information theory, because including the
observer in the equation admits a new level of intelligence to the system. In
the old metaphor, we ignored the observer in an attempt to avoid any taint of
subjective interference in determining reality. In the new metaphor, the
observer plays an important role in defining the reality, because it is the observer’s participation
that makes the difference!”
I interrupt
excitedly: “Oh, the consciousness of the observer—that’s the link to quantum
mechanics.”
“Yes, exactly.
Now, back to my point that information—the difference that makes a
difference—does not change with time or space.” To illustrate his meaning, Bob
points to a cup of tea on the table. “The difference between me and the cup remains the same whether I’m here or I’m in Alaska. Information is
not
dependent on time or space, as is matter and energy, but exists regardless of
these limits!”
I’m aware that
Gottesman is moving onto some very radical ground with very profound
implications. If information exists outside of the confines of time and space,
matter and energy, then it must belong to a very different realm from the
concrete, tangible realm we think of as “reality.” And since information in the form of the biochemicals of emotion is running every system of the
body, then our emotions must also
come from some realm beyond the physical. Information theory seems to be
converging with Eastern philosophy to suggest that the mind, the consciousness,
consisting of information, exists first, prior to the physical realm, which is
secondary, merely an out-picturing of consciousness. Although this is about as radical as my scientist’s
mind will let me get, I’m beginning to understand how such a view could coexist
comfortably with the kind of science I’ve been doing.
“But let’s move
on to another important point of information theory, that of feedback,”
Gottesman continues. “According to Bateson, the greatest bite out of the apple
of knowledge since Plato was the discovery of feedback. The idea of feedback
comes from cybernetics, the scientific study of control processes in different
systems. The word cyber derives from
the Greek ‘kybernetes,’ meaning ‘that which steers’ or ‘the helmsman’—the
steerer of a ship. Now, the helmsman steers the ship by constantly adjusting
the tiller in response to the information— or feedback—he is receiving from visual readings—via either sight or instrument. This is an example of a
feedback loop.”
“Yes,” I interrupt. “I’m familiar with this concept
from my brief
experience of having crewed in sailboat races in the Chesapeake Bay. The
common mistake of the inexperienced sailor is to anxiously trim the sails
before receiving information about the boat’s altered
speed and direction. I had to learn to wait
the seconds or even minutes until the sail catches the wind and the helmsman
adjusts the tiller in response—then I could make use of the information, the
feedback, to further trim the sails accurately.
“And the same
principle functions in the psychosomatic network,” I continue, “which is
analogous to a boat sailing along as the result of a series of feedback loops.
Cells are constantly signaling other cells through the release of
neuropeptides, which bind with receptors. The signaled cells, like the helmsman or the sail trimmer, respond by making
physiologic changes. These changes then feed back information to the
peptide-secreting cells, telling them how much less or how much more of the peptide
to produce. This is how both the body and the
sailboat
move forward, through a series of rapid feedback loops. A system is healthy—or
‘whole,’ a word that shares its origin with the word ‘health’—when these
feedback loops are rapid and unimpeded, whether they are occurring between
peptides and receptors
or between the helmsman and his tiller.
I recently read in Fritjof Capra’s new book, The Web of Life, how Walter B. Cannon, the lamed
physician-physiologist working in the 1920s, first formulated the concept
of homeostasis as an inborn system of internal checks and balances to provide a relatively constant
state within the body. Capra points out that Cannon’s idea is perhaps the first
vision of the organism as a closed circle of information flow.”
“You’re right,”
Gottesman says. “And I use the rapid feedback loop concept when treating
patients. As you yourself have experienced during
our consultation, I ask lots of questions to get my patients to pay
attention to what’s going on with them, to self-monitor. It takes time, which
most doctors won’t spend, but I do it
because I want my patients to become aware of the difference that makes a difference to them. Those who are able to respond in
this way, to do their own self-monitoring, get well faster, because they have
more intelligence at work in their systems, more information to make changes
that bring about improvement. So I think ultimately it saves time.”
I’m thinking:
This concept of the rapid feedback loop—it even explains the way I have done my
science over the years. Most of the success my team and I have had resulted
from a shortened feedback loop between performing an experiment and then using
the results to make immediate changes or
adjustments. In our AIDS research, Michael and I cracked the mystery of the
peptide that fit the AIDS virus receptors by initiating a new experimental question each morning, getting the results
in the afternoon, and then poring over the data every night for changes to be
made the next day. This was part of my legacy from Sol Snyder—his philosophy of
the rapid, one-day turnaround, what he called the “speedy flier.”
“Oh, I
understand,” Nancy says, having thought over Bob’s words and now ready to
respond. “The faster or tighter the feedback loop, the more intelligence
available to the system, whether it is used for health or for
sailboat racing.
Between
doctor and patient, then, the more communication, the better, and the better
the communication, the more health!”
We are silent for
a moment. But suddenly Bob is off and running in a new direction:
“So, in my mind, all of this talk about metaphors
and feedback loops points to
a
very basic question: Is the physical world of matter and energy ‘real,’ and do
molecules really exist?”
I’m glad he’s gotten back to what I call the ultimate chicken-and-egg question
—whether consciousness precedes the physical or vice versa.
“I think it’s best to look at
molecules and the rest of physical phenomena as metaphors, devices
we use in order to talk about something.” Bob continues.
“The equator doesn’t really exist, but as a metaphor it’s very useful, and in
navigation, lives depend on it. I know these are uncomfortable realms for most
mainstream scientists, but you seem quite liberal in your thinking, so I’m
hoping you can absorb the more mystical significance of what I’m saying.”
Could I ever.
Gottesman continues: “Consider
that the body itself may be a metaphor, just a way of referring to an
experience we all have in common. Maybe it’s that we don’t have consciousness, but consciousness
has us.”
Now we are on to
a very Eastern drift, but I can follow with an open mind, thanks to the experiences I’ve had in the last decade or so. Deepak’s
impact on me in such matters
has been particularly profound, allowing me to make my own contribution to the
give-and-take of this conversation.
“Let me tell you
a story Deepak Chopra told an audience when he was introducing me for a talk at his institute,” I offer. “He was on a visit to India when he met up with some wise
men—the rishis, or sages, who are the spiritual leaders in that country. In the
course of conversation, he attempted to explain my work to them, the idea that
neuropeptides and receptors communicate as information molecules. But they
could only shake their heads and give him very quizzical looks. Finally, the
oldest and wisest appeared to suddenly get it. He sat straight up and, with an
expression of great surprise, said, ‘Oh, I understand. She thinks these
molecules are real!’”
My tale gives us
all a good laugh, and on that note we feel we can adjourn our discussion of the
ultimate nature of the universe tor the day. The warm sunlight that filled the living room at the
beginning of on our talk is now faded, and the sudden chill signals me it is
time to be moving on.
Susan, who has
been quietly absorbing our discussion up until now, turns to me and, while Bob and
Nancy are walking toward the door, offers some wise, parting counsel: “You seem
to be a person who has accomplished so much in the world of science. But I
sense in you a desire to get more in touch with your soul, your spiritual self,
your true femininity. Perhaps this may mean letting go of control, letting your
husband take the lead in your joint research while you focus more on your health and your new way of being. There’s a part of yourself that
is longing to be born and requires only your nourishing
attention.”
She was right. Wasn’t
Susan offering me another version
of the lesson Deepak had given
me, to stop trying so hard, stop forcing the issue and pushing to develop my research, my AIDS drug? Instead, I should work to understand my life as a conversation, a
web of interactions and relationships all connected with each other and all heading
in the same direction, without
my needing to push all the time. This was one of the
lessons of meditation. Control belonged to the old metaphor, and was no longer
useful in forwarding my goals, my quest. It was time to open up space to let
Michael do more, and also to work with other scientists in joint research
efforts, abandoning my stance as lone standard-bearer on the battlefield of
AIDS research.
Our jars of
hormone cream clutched firmly in our hands, Nancy and I said good-bye and
started out on our journey back to Santa Barbara. As we rose from the valley
and ascended to the pass through the mountains, we were both lost in our
thoughts about the day’s events.
WITH THIS new understanding of information science,
I was beginning to see my theory that the neuropeptides and their receptors are
the biochemicals of emotion in a new light. The emotions are the informational
content that is exchanged via the psychosomatic network, with the many systems,
organs, and cells participating in the process. Like information, then, the
emotions travel between the two realms of mind and body, as the peptides and
their receptors in the physical realm, and as the feelings we experience and
call emotions in the nonmaterial realm.
Information! It
is the missing piece that allows us to transcend the bodymind split of the
Cartesian view, because by definition, information belongs to neither mind nor body, although
it touches both.
We must accept
that it occupies
a whole new realm,
one we can perhaps call the “inforealm,” which science has yet to explore. Information theory
releases us from the trap of reductionism and
its tenets of positivism, determinism, and objectivism. Although these
basic assumptions of Western science have been ingrained in our consciousness
since the sixteenth and seventeenth centuries, information theory constitutes
such a new language—a rich language
of relatedness, cooperation, interdependence, and synergy rather than simple force and
response—that it helps us break out of our old patterns
of thought. Now we can begin to conceptualize a different
model of the universe, and of our place in it.
BODYMIND
These were my
ruminations as we pulled through the narrow mountain pass, our car hurtling us
toward the pink sunset that spread out across the sky above Santa Barbara.
“So
how was your consultation?” Nancy finally asked, breaking the silence. “Like nothing I’d ever find back in D.C., I can tell you that,” I responded. “I
actually
felt good after he was done, and not as if I were a piece of meat that had just passed
inspection. In fact, I don’t
think I’ll ever want to go to a regular doctor again—unless I fall off a
building or my appendix erupts,” I quipped, and we laughed.
Nancy laughed
again. “I know what you mean. I felt the same way.” “Actually, it’s been a long time since I’ve visited a regular doctor. I mostly go
to
chiropractors or get massage therapy in combination with nutritional advice for whatever
ails me these days. Lately,
I’ve been exploring Ayurvedic medicine, which is the traditional practice of India.
Western-trained doctors like Gottesman are rare—an info-doctor!”
“Really, I liked
what he was saving about the new metaphor,” Nancy said. “It gives me a new way
to think of myself. I’m no longer a machine made up of a both being pushed around by a brain, at the mercy of an
electrical charge to keep my heart beating and my synapses crackling. Instead,
I can now see myself as an intelligent system, one that involves a massive and
rapid simultaneous exchange of
information between mind and body. My cells are literally talking to each other, and my brain is in on the
conversation!”
I had to agree.
What Nancy was on to was not only a new self-concept, but a new sense of
integrity, something I too was on the edge of embracing in my life, and which
all my research pointed toward. The new self-image was one of an integrated body and mind,
one with intelligence, an emotional intelligence, even a soul or spiritual component. And the undeniable implication was that each of us is a dynamic system with a constant
potential for change in which self-healing is
the norm rather than the miraculous. I nodded and waited for more.
“And now that I
know my body has wisdom, this calls for a new kind of responsibility on my
part. I can no longer act like a dumb machine and wait to be fixed by the
mechanic—otherwise known as the doctor. Now I have the potential to consciously intervene in the system
myself, to take an active role in my own healing. I’m both more powerful and more
responsible in creating
the health I
experience than the dumb machine I used to think I was.”
“Exactly!” I agreed, for I now saw the connection between
Nancy’s “conscious intervention” and what Deepak talks about in his
books when he describes meditation as intention—the plan, the agenda,
the focus. When I say this to Nancy, she gets it
immediately, “Yes,” Nancy said, herself a meditator for many years. “And that’s
how I understand meditation to work, as a process of putting forth my
intention, having a purpose, and then simple paying attention to whatever that
is by staving focused mentally. The focus could be a mantra, my breath, or some
other point of concentration, such as healing my body or sending peace to the
planet. I know l m already intervening unconsciously
in the system through my normal everyday thoughts, even sometimes to the
detriment of the system—you know, overadjusting the sails, to use your phrase,
or somehow gumming up the works, the natural balance—the homeostasis, as Cannon called
it. And so I can choose to stop doing that, to intervene with intention.”
I nodded. In the
old reductionist model, chronic illness such as heart disease and cancer are
seen as forces attacking the body, making us helpless victims, incapable of any
response outside of high-tech medical treatments. But the concept of conscious
intervention adds a new element to the equation, a scientifically valued
intelligence that can play an active role in the healing process. Meditation is
just another way of entering the body’s internal conversations, consciously
intervening in its biochemical interactions.
We arrive back
in Santa Barbara shortly after sunset. I intend to go to bed early, still
needing to catch up to West Coast time. But my bodymind is abuzz with the new ideas
we’ve been tossing about, many of which I plan to explore and digest, perhaps sharing some of them
with my conferees in Anaheim on the morrow.
HAPPINESS
Disneyland, the
magical kingdom of eternal childhood, the promise of happiness everlasting!
When I received
an invitation to present at a conference that would be held at the Disneyland
Hotel, I was a bit surprised at first. Maybe it’s my old-paradigm roots, but
the incongruousness of having a medical meeting in a location associated with cartoons and fantasy—well,
it struck me as odd. But as I read the title and schedule of speakers and events, I quickly caught on. “Medicine,
Miracles,
Music, and Mirth.” This was to be a coming together of researchers,
practitioners, musicians, even comedians to focus on how psychoneuroimmunology,
non-traditional healing, and fun all interface.
I was actually thrilled
by the prospect of being at Disneyland and staying right next
door to the theme park of my childhood dreams at the Disneyland Hotel. Back in the fifties,
when I was growing up in Levittown, New York, every
normal, red-blooded American kid I knew dreamed of winning a trip to
Disneyland. The closest I ever got was wearing my Mouseketeer ears while I sat
for hours in front of the TV watching the Mickey Mouse Club. The idea of my
family taking a trip to California and entering the fabled gates was
unthinkable. No one we knew had ever gone to Disneyland. It might as well have
been on Mars.
Now, forty years
later, I am stepping out of the airport shuttle at the Disneyland Hotel. Above me, the monorail
cruises along, packed with happy campers on their way to the fairy tale come
true, and in the distance, the peaks of some mysterious castle loom, suggesting
the land of make-believe is not so far away.
It all seems a bit surreal to my scientist’s mind, although the eight-year-
old inside me is glad to be here.
And everyone
seems so happy—the bellmen, the registration clerks. I know I’m supposed
to be happy—I’ve finally made it to Disneyland! But, to be honest, I’m mostly
feeling tired from jet lag, and the thought that my fourteen-year-old son Brandon is three thousand
miles away and unable to share this with me makes me a little sad. And I
miss Michael. I left D.C. in the
midst of a crucial time for Peptide T, just as we had gotten word that an
outside evaluator was coming to our lab at Georgetown to perform some new tests,
which, if successful, might advance our work significantly. Leaving Michael to handle it on his own wasn’t easy, but I console
myself that it is part of my new attitude of trusting to the flow. Still, I can’t help but wonder how things are going,
and I have a hard time resisting the impulse to pick up the phone.
Let it go, I tell myself. I’m here to have some fun!
I decide to get a bite to eat and check
out the scene at one of the many
outdoor cafes wrapped around the central waterway. Familiar Disney tunes waft
through the air, piped in over an all-pervasive sound system, and I find myself
singing along with many of my childhood favorites as I stroll: “When You Wish
upon a Star,” “Someday My Prince Will Come.” Seating
myself at a table. I order a meal and relax.
“Are we having fun yet?” The popular catchphrase runs through my thoughts
as
I observe the scene. How all-encompassing is the Disney myth of happiness! I
grew up on it and so did my kids—and so will theirs, most likely. For us baby
boomers, especially, the land of Disney looms large as a symbol of childhood
happiness, the kind we were supposed to have, wanted to have, but often didn’t
have. Recently, I read a poll in which Americans were asked the question: Are you happy with your life? A surprisingly high percentage
responded yes.
Surprising because
the statistics show that mood disorders such as depression and anxiety are on the
increase, becoming more widespread all the time. Since clinical depression is a
potentially fatal disease, depression-related suicides are also on the rise. I
have to ask: If everyone’s so happy, why is depression at near- epidemic
proportions in our society? Are we all in denial, clinging to what we believe
is the cultural norm, what is socially expected of us? Are we ashamed to admit
we might be sad, unhappy, disappointed, and not altogether satisfied with life?
As discussed earlier, many people
view depression as anger turned
in on itself, unexpressed,
buried below consciousness where it seems to be controlled but slowly implodes. As a culture, we keep
our feelings hidden, afraid to express them
honestly for fear others will be indifferent to our sorrows
or alienated or hurt by our anger. Better to deny
feelings, to suppress them, we tell ourselves, go through the motions of
happiness and pretend to have fun—until the day the bottom falls out and the family physician hands us the diagnosis: depression.
It is this problem
of unhealed feeling, the accumulation
of bruised and broken emotions, that most people stagger under without ever
saying a word, that the mainstream medical model is least effective in dealing with.
When people do seek
help, often what is offered
through mainstream psychology and psychiatry is
what I call “talk and dose” therapy: lots of talking and even more pills, which
are supposed to make the unacceptable feelings go away. A treatment, yes, but one that really only Band-Aids the
symptoms and consigns people to a drug dependency rather than directing them
toward an opportunity for really healing feeling.
What is not
given much attention by the mainstream is what it means to be antidepressed,
i.e., happy. I believe that happiness is what we feel when our biochemicals of
emotion, the neuropeptides and their receptors, are open and flowing freely
throughout the psychosomatic network, integrating and coordinating our systems, organs, and cells in a smooth and
rhythmic movement. Health and happiness are often mentioned in the same breath,
and maybe this is why: Physiology and emotions are inseparable. I believe that happiness is our
natural
state, that bliss is hardwired. Only when our systems get blocked, shut down,
and disarrayed do we experience the mood disorders that add up to unhappiness
in the extreme.
I return to my
hotel room after a brisk walk around the grounds and find a message from
Michael, but it’s too late on the East Coast to return his call. Sleep comes
easily.
UNHEALED FEELING
The next morning,
after my lecture, I’m making my exit toward the stairs leading up to the main
lobby, when I hear a voice behind me.
“Dr. Pert? Do you have a moment?”
Barely. I’ve been invited
to lunch by two women who approached me after the lecture.
They were a most unusual duo, a physician and a psychic, friends who had come to the conference together. I
was planning to sit in the sun for the next half hour before meeting them at an
Italian bistro.
However, as I
turn around I see the warm, smiling face of a very determined woman pursuing me
up the stairs, “Sure I do,” I say, finding her hard to resist, even though I
have no idea what I’m getting into.
We make our way
to a sunny spot alongside the centrally located watercourse and seat ourselves
at a table. Happy kids and less happy parents pedal their brightly colored boat bikes along the
water as we place an order for cold drinks. Marilyn, it turns out, is a
licensed marriage, family, and child counselor, an MFCC, with a thriving practice in Northern California, where,
she tells me, she’s noticed a disturbing trend. She wastes no time getting to
the point.
“It seems that
ten years ago when I first began my practice, I rarely saw a client who was on
antidepressant drugs,” she tells me. “Mavbe Valium or Librium occasionally, but
those are relatively harmless muscle relaxants. Now I’m seeing Prozac, Zoloft,
Paxil, Serzone, Tofranil. Most of my clients are on one or another.”
I understand
Marilyn’s puzzlement about this sudden upturn in the use of prescription
antidepressant drugs and I’ve talked to many psychotherapists who, like Marilyn,
are confused and concerned about what appears
to be the ubiquitous medical solution to the epidemic of depression.
“Just recently.”
she continues. “I asked a psychiatrist who’s affiliated with my counseling
group why so many of my clients are getting prescriptions for antidepressants. He explained that the drugs correct chemical
imbalances in the
brain
that are the cause of depression, and, for some people, they are more effective
than other kinds of therapy.”
As Marilyn
talks, my thoughts flash back to my dinnertime musings the night before.
Antidepressant medications, along with many of the drugs given during
childbirth, are examples of drugs that would be given much more sparingly if there were better knowledge of the full
range of peptidergic activity in the bodymind.
“What are these
drugs doing to our bodies and minds?” she asks. “Do you think so many people
should be taking them?”
In my lecture
that morning, I had explained how the psychosomatic network operates through a
series of delicately balanced peptidergic feedback loops, and when the flow of
chemical information is unimpeded, it results in homeostasis, or balance. The
question of how legal and even illegal drugs enter that network and affect the
natural homeostatic balance was only hinted at in my talk.
“Lets talk about what these drugs do first,”
I begin. “Basically they go to work at the level where brain cells
are communicating with each other across the synapse. Chemicals are squirted
out by one and bind to the receptor of another.
If too much juice comes out, there is something called
a ‘re-uptake’ mechanism by which the cell reabsorbs the
excess. The classical understanding of depression is that there is a shortage of the neurochemical serotonin
secreted by the brain cells. To
remedy this, an antidepressant drug is used to block the re-uptake mechanism,
allowing the excess serotonin to flood the receptors, and thereby correct the
imbalance.”
“Sounds
very precise, like they know just what to do,” Marilyn interjects. “Yes. But it’s a false precision, because it doesn’t measure what else is
going
on
in other parts of the brain and body when these drugs are administered.
Remember, we’re dealing with an immensely complex psychosomatic network, one with trillions of shared components—the peptides and receptors— throughout many systems and
organs. Your intestines, for instance, are loaded with serotonin receptors. What happens when these receptors get
flooded with excess serotonin as a result of taking Prozac, for example? Well,
it’s known that people on antidepressants often have gastrointestinal
disorders. And think what might be happening to cells in the immune system that
also have these same receptors on their surfaces. We could be inadvertently
affecting the ability of our natural killer cells to attack mutated cells that
are on their way to becoming a cancerous tumor. But no one’s doing the research
to explore these kinds of effects.”
“Certainly not
the pharmaceutical companies,” Marilyn says, quickly picking up on my drift. I
nod.
“And the
antipsychotic drugs—Haldol, Thorazine, Risperdal, Clozaril—work the same way
and have many of the same side effects, only instead of blocking the re-uptake of
serotonin, they block the receptors for dopamine, another neurotransmitter.”
“Besides
gastrointestinal disorders, what other kinds of effects can occur?” Marilyn
asks, obviously concerned.
“There’s a
cascade of things going on, kind of like a waterfall that starts at the top but
initiates changes all along the way to the bottom. For instance, when the
dopamine receptors in the pituitary glands of women are blocked, prolactin is
released, a hormone that stops ovulation during lactation, so women rarely get
pregnant while breast-feeding, women on these drugs stop menstruating and level
off as long as they’re
on the drug, in a constant state
of PMS. complete with water retention and weight
gain.”
“Sounds
like they’d be good candidates for Prozac.” Marilyn says wryly. “And that’s exactly what often happens, I’m sorry
to say! These women are
then
given antidepressants on top of the antipsychotic drug. This is not uncommon,
this treatment of what is called an “iatrogenic disorder,” meaning a
physician-caused disorder stemming from the treatment that’s supposed to cure
the patient.”
Looking at
Marilyn’s now grim face. I’m getting the feeling that she will be on the brink
of depression herself if I keep going clown this road. “Why don’t you join me
and some new friends for lunch?” I ask her, trying to switch gears. “Maybe
they’ll be interested in hearing what the latest research is telling us about the good news—the potential for
mindbody approaches to cure mood disorders.”
NEW LIGHT ON
DEPRESSION
We go in search
of Kate and Dee, the doctor and the psychic, who by now are waiting in line for a table. Once seated,
we all choose large salads from the menu, and enjoy our meal while getting
further acquainted. I am intrigued by the idea of their friendship, and grill
them politely. How do two people from such diametrically opposed paradigms
meet, much less become close friends? The story unfolds that during her internship. Kate participated in a study that showed
certain
forms of hands-on healing; and prayer were effective in speeding recovery rates
for surgery patients, and Dee was one of the healers. Since then, they’ve
become good friends, pursuing a common interest in the mindbody healing
connection. Which gets us back to the topic Marilyn and I have been discussing,
the concept of depression as a mindbody disease and the medical professions
tendency to overprescribe and overmedicate it, while ignoring possible side
effects.
“My sister has
been on Prozac for years.” Kate blurts out. “I don’t think we know enough about
the stuff, and I’ve told her so. But she’s convinced that the drug is the
answer to her problems. And she refuses to deal with any of the underlying
issues that I believe to be at the heart of her problems.”
“And right you
are to be concerned,” I begin, delighting in the chance to take my listeners a
little deeper into the science, “Just recently, researchers at the National
Institutes of Health have found a link between depression and traumas
experienced in early childhood. Studies have shown that abused, neglected, or
otherwise unnurtured infants and children are more likely to be depressed as
adults, and now we have a way to understand the link between the experience and the biology. It all
relates to something called the hypothalamic-pituitary- adrenal axis.”
Our waiter
arrives just as I am getting launched. A platter of chocolate mousse, cream puffs, and cheesecake is
thrust under our noses by a beaming young man. We admire the goods politely,
but no one takes him up. Ah, California, land of the healthy and conscious! He leaves and I get back on track.
“Very simply, the
hypothalamus is part of the emotional brain, (he limbic system, and its neurons
have axons that extend into the pituitary
gland, which sits below it.
There axons secrete a neuropeptide called CRF—cortical releasing factor—which
controls the release of another informational substance. Thus, when CRF hits the pituitary gland, it
stimulates the secretion of ACTH, an informational substance that then travels
through the bloodstream to the adrenal glands, where it binds to specific
receptors on adrenal cells.” I am getting some puzzled looks. “Is everybody
with me so far?”
“Adrenal
glands—don’t they have something to do with adrenaline? The ‘fight or flight’
response?” Dee asks me.
“You’ve got it.
Adrenaline is what causes the fight-or-flight alarm response, which is the
body’s natural, unconscious reaction to threats, either real or imagined. Our
ancestors put it to good use when the saber-toothed tiger threatened to leap
from a precipice and have them for lunch. It’s often characterized by an energy
rush, dilated pupils, a racing heartbeat—all
conditions
that enable us to deal effectively with perceived danger But another thing that the adrenal
glands do, which
is what happens when ACTH hits them, is that they begin to make steroids.
These are not the steroids associated with sex and the reproductive system,
however.
“The steroid they
make is corticosterone, a substance that is necessary for healing and damage
control when an injury has occurred You’ve all probably applied cortisone cream
for a skin rash or had a cortisone shot to treat poison ivy or oak.
“Now, here comes
the connection to clinical depression. Ever since studies done thirty years
ago, we’ve known that stress increases with increased steroid production. Depressed
people typically have high levels of these stress steroids. In fact, depressed
people are in a chronic state of ACTH activation because of a disrupted
feedback loop that fails to signal when there are sufficient levels of steroid
in the blood. So the CRF-ACTH axis just keeps pumping out more and more
steroids. Autopsies almost always show a tenfold higher level of CRF in the cerebrospinal fluid of those who
killed themselves compared to those who died from other causes.”
“Sounds like
this CRF is the depression peptide.” Kate says. “Assuming that a given peptide has a
specific tone, that is.” she continues, referring to some of the more
speculative excursions of my lecture.
“It sure looks
that way. We could say that CRF is the peptide of negative expectations, since
it may have been stimulated by negative experiences in childhood. There are
animal studies, for example, showing that monkey babies deprived of maternal
nurturing, neglected or abused, in effect, have high levels of CRF and so have
high steroid levels. Remember, it’s a feedback loop that is out of control.
Depressed people are stuck in a disruptive feedback loop that resists any kind
of drug therapy that aims at suppression of the steroids.
Eventually,
there is so much CRF in the system that fluctuations of other peptides
throughout the organism are curtailed, leaving ever lower possibilities in the range of behavior. In baby monkeys,
this takes the form of failure to groom or repetitive behaviors that don’t seem
to have any purpose. In humans, the result can be extremely limited patterns of
behavior and response, which eventually drive people into an emotional black
hole.”
“My sister is
convinced that if only her husband hadn’t left her, everything would be
okay—she can’t seem to get past that,” Kate interjects.
“Yes, and the
reason we can get stuck like this is because these feelings get retained in the
memory—not just in the brain, but all the way down to the
cellular
level. This is how it works: As CRF levels increase in highly stressed infants and children, the receptors for CRF become
desensitized, shrinking in size
and decreasing in number. These changes happen when receptors
are flooded with drug, whether it’s drug your body produces naturally or
a drug you buy at a pharmacy. The memory of the trauma is stored by these and
other changes at the level of the neuropeptide receptor, some occurring deep in
the interior of the cell at the very roots of the receptor.
This is taking place
bodywide. Although such changes can be reversed and need not be permanent, this
takes time.”
“So what’s the
latest remedy from the researchers?” Marilyn asks. “More drugs to decrease CRF
production or block CRF receptors?”
“Unfortunately, drug therapy is the main direction for research at this time.
But the good news is that these findings let us see the potential for
nondrug interventions, new kinds of treatments for mood disorders. Remember the
stressed-out monkey babies? In another study to determine maternal influence, a
group of monkey babies was raised by a fake monkey mother, a wire-and-cloth
structure with milk bottles instead of breasts. The babies were fed but not touched, cuddled, or held. They soon had
all the signs of trauma and depression, as would be expected
in light of all we’ve just talked about. But they were cured
—the
stress symptoms reversed—when researchers brought in what they called a ‘monkey hug therapist,’ an older monkey who constantly hugged and cuddled the stressed-out baby monkeys. So
what was going on? The hugging broke the feedback loop, sending the message ‘No more steroids
needed,’ damage over and done with! The chronically
elevated CRF levels came down.”
“So when we see those bumper stickers ‘Hugs Not Drugs,’ we should take
them more seriously!” Dee points out. We all laugh at the realization that the
science I’ve been laboring at such length to explain is obvious enough to have
become popular bumper-sticker wisdom.
So obvious. I’m
thinking, but not obvious enough to change the agendas of pharmaceutical
companies or the mainstream medical model. As a researcher on the drug frontier
for over twenty years, I have to depart from the opinion of most of my
colleagues in the mainstream and say that less
is best. The implications of my research are that all exogenous drugs are
potentially harmful to the system, not only as disrupters of the natural
balance of the feedback loops involving
many systems and organs, but because of the changes that happen at the level of
the receptor.
Each of us has his or her own natural pharmacopoeia—the very finest
drugstore available
at the cheapest cost—to produce
all the drugs we ever need
to run our bodymind in precisely the way it was designed
to run over centuries of
evolution. Research needs to focus on understanding the workings of these
natural resources—our own endogenous drugs—so that we can create the conditions
that will enable them to do what they do best, with minimal interference from exogenous substances.
But when they can’t do their job, such research will also enable us to create
mimetic drugs that imitate the natural substances and cause minimal
interference with the bodymind’s balance because they have been developed with
an awareness of the whole psychosomatic network.
“Of course, I’m
not suggesting that hugs alone can cure all our major ills.” I say. “The prescription drugs do serve a
purpose, and I recognize that they save people’s lives. It I have a bad
infection, I’m going to use an antibiotic. If I have a serious clinical
depression, I will take an antidepressant. But from my research with the
endorphins. I know the power of touch to stimulate and regulate our natural
chemicals, the ones that are tailored to act at precisely the right times in
exactly the appropriate dosages to maximize our feelings of health and well- being.”
I had experienced
this personally when, during the early days of our relationship. I jokingly
called Michael my “monkey hug therapist.” because we were in one gigantic,
continual hug most of the time, and we felt happy and high most of the time. We did some of our most exciting work “under the influence”
of those hugs. Later we relied on them for solace. In fact, sometimes I wonder how we would ever have withstood the
stress that we encountered in the early days
of our Peptide T struggles without those hugs.
“I get it,” Kate
says thoughtfully. “You’re saying that by bringing touch into the healing
process, we may be able to offer another kind of help to people with mood
disorders. It’s the other half of the equation: Just as we can harness the
power of our minds for physical healing, so can we do physical things to help heal our feelings.”
“So that’s why
people feel better when they get a good massage or other kinds of hands-on
healing,” Dee joins in.
But Marilyn seems
disturbed by this turn of the conversation. “Well, the sorry fact is that most of us in the mental-health professions, especially the
psychiatrists, the M.D.s, who prescribe the drugs, would get our licenses
revoked if we touched our clients!”
“You’re right.”
I respond. “Mainstream medicine is notoriously touch-phobic
for
the most part, dating back to the original days of the Cartesian split and
perpetuated by ignorance of how sensory information is processed in the
psychosomatic network. There’s
a whole history, beginning with Freud, who laid the cornerstone of modern
psychiatry as a no-touch affair back in the Victorian
era when people were so uncomfortable with their bodies that any kind of touch
was—God forbid—considered part of the sexual domain. Other contenders, such as
Wilhelm Reich and Alexander Lowen, made attempts at introducing a more
body-linked approach, believing the body to be a gateway to the mind and
working with different forms of emotional release. But they were ferociously
marginalized, even persecuted in Reich’s case.
“In recent
years, however, there have been loads of animal and human studies that show the benefits
of touch, not only for depression but for illnesses that have physical symptoms as well. And I’m glad to report
that this knowledge is entering the medical mainstream, if rather slowly.”
Our bills arrive just then, and on an upbeat note, we decide to move on.
Outside,
the crowds have thinned, with most of the hotel guests having left to spend the
day at the park, and there is a peaceful ambiance to the place. Together we
stroll back toward the convention hall to catch the remaining presentations
before the afternoon workshops begin. But halfway there, I tell the others to
go ahead without me. I’m listening
to my bodymind, and the message I am getting is to kick back,
find a warm concrete slab out of the way of the traffic, and stretch out in the sun.
BODY PSYCHOTHERAPY
Our lunchtime talk has touched
on a frequent theme in my thoughts
of late, the question of healing feeling, something so
desperately needed in our society, its reflected by both the rising numbers of people on
antidepressant medications and the escalating use of illegal drugs. In my mind,
both kinds of user—the one who gets the drugs from a doctor and the one who
buys them from a dealer—are doing the same thing: altering their chemistry with
an exogenous substance that has widespread effects, many of which are not fully
understood, in order to change
feelings they don’t want to have.
My research has
shown me that when emotions are expressed—which is to say that the biochemicals
that are the substrate of emotion are flowing freely— all systems
are united and made whole.
When emotions are repressed, denied,
not
allowed to be whatever they may be, our network pathways get blocked, stopping
the flow of the vital feel-good, unifying chemicals that run both our biology
and our behavior. This, I believe, is the state of unhealed feeling we want so
desperately to escape from. Drugs, legal and illegal, are further interrupting
the many feedback loops that allow the psychosomatic network to function in a
natural, balanced way, and therefore setting up conditions for somatic as well
as mental disorders.
But the idea of
the network is still too next to have affected the way mainstream medicine and
psychology deal with our health and our illnesses. Most psychologists treat the
mind as disembodied, a phenomenon with little or no connection to the physical
body. Conversely, physicians treat the body with no regard to the mind or the
emotions. But the body and mind are not separate, and we cannot treat one
without the other. My research has shown me that the body can and must be
healed through the mind, and the mind can and must be healed through the body.
The so-called
alternative therapies that focus on somatic-emotional release understand this,
and it is through them that we can complement what is offered by the mainstream. In the case of
treating mood disorders and other mental unwellness, the mainstream misses a
lot by excluding touch, by ignoring the fact that the body really is the
gateway to the mind., and by refusing to acknowledge the importance of
emotional release as a mindbody event with the potential to supplement or even
sometimes replace talk cures and prescription pills.
I first came in
contact with somatic-emotional release approaches, also called “body
psychotherapy.” at Esalen in California, when I gave a talk there in the early eighties. The Greeks and Romans had
their baths, their spas, their temples of healing at places like Epidaurus, and we have
Esalen, where beautiful, natural springs come from deep within the earth to
fill the pools perched high on a bluff over the Pacific
at Big Sur. Which I spent some time in the baths of Esalen,
I met many massage therapists, chiropractors, and theorists who saw my
research as a confirmation of what
they were seeing in their practices. I was very impressed by their power to simultaneously access the emotions
through various kinds of body work while enlisting the power of the mind
through talk, thus creating what seemed like a loop of healing.
This exposure
opened me to other kinds of alternative healing modalities that aim to release
emotions through different processes, but always by involving some form of touch. One of the most dramatic experiences I had occurred
in 1985 as a result of a chance encounter with an old friend and Bryn Mawr
alumna.
Caroline Sperling, a psychologist who founded her own cancer foundation. It was
shortly after my divorce from Agu. When she asked me how I was doing. I told
her I was fine, that everything was amicable and civilized. But she stopped me
in midsentence.
“You’re lying,”
she said bluntly. “How can you not have pain?” I was taken off guard. “Don’t
you know?—that’s how people get cancer. By burying their emotions, deriving and
repressing them.”
Intuitively, I knew she was right, and I listened. Caroline,
who had been living with cancer for three years, told me about a
practice she’d developed that combined techniques from Janoy’s primal scream
with Lowen’s bioenergetics to bring about emotional release through movement,
hugging, and screaming. Soon afterward I attended one of lier day long sessions
and found that it enabled me to unleash the torrent of anger and hurt I’d been
bottling up inside of me ever since the divorce. I returned home eager to tell
Michael all about it, but was so exhausted
I went straight to bed and slept for almost twenty-four hours.
It was at a
Common Boundary meeting in 1988 that I met Bonnie Bainbridge- Cohen, who introduced me to her bodymind centering
technique, an approach that grounds mental, emotional,
and spiritual elements in the physical body. (The common boundary that gives
its name to the organization is that shared by psychology and spirituality.) I
was impressed with Bainbridge-Cohen’s very accurate understanding of how trauma
and stress are forms of information overload. She used the mechanism of nerve
reversal to explain how impulses are rejected by the brain and bounced back to
other areas of the central nervous system, where they are stored in both the autonomic
and somatic tissues.
Bonnie’s
approach uses movement and body work and is based on these psychological and
physiological principles.
More recently. I have discovered a new breed
of chiropractors who differ
from the conventional ones in that they bring an awareness of energetic, emotional levels into
their healing. One of these is Donald Epstein, who founded the school of Network
Spinal Analysis Chiropractic and wrote a book entitled The 12 Stages Healing: A Network Approach to Wholeness. I have had some
profound experiences while being treated with this method, invoking the release of traumatic stored memories from the
autonomic ganglia on either side of the spinal cord. Often visual images
related to the trauma have surfaced in my consciousness as part of the
emotional release, which I can then talk about with the practitioner.
Another healer I respect tremendously is John Upledger,
creator of
craniosacral
therapy, a modality that aims to balance the cerebrospinal fluid through gentle
manipulations of the cranium. He talks about “somato-emotional cysts.” pockets
of blocked emotion held in the body, causing a breakdown in the energy How and
general health. Epstein and Upledger both refer to “feeling the energy” as they
do their work, while other practitioners report actually seeing energy move in
the body as the emotions are released.
What is this
“energy” that is referred to by so many alternative healers, who associate it with the release of emotion and the restoration of health According to Western medical terms,
energy is produced strictly by various cellular metabolic processes, and the idea that energy could be connected
to emotional release is totally foreign to the scientific mind. But many
ancient and alternative healing methods refer to a mysterious force we cannot
measure with Western instruments, that which animates the entire organism and
is known as “subtle” energy by metaplusicians. prana by Hindus, chi by
Chinese. Freud called it libido.
Reich called it orgone energy, Henri Bergson called it élan vitale. It’s my belief that this mysterious energy is actually
the free How of information carried by the biochemicals of emotion, the
neuropeptides and their receptors.
When stored or
blocked emotions are released through touch or other physical methods, there is
a clearing of our internal pathways, which we experience as energy. Free of the Western dualism
that insists on disanimated flesh,
healers from various Eastern and alternative modalities can literally
see the mind in the body, where it does indeed exist, and are adept at
techniques that can get it unstuck if necessary. In tact, almost every other culture but
ours recognizes the role played
by some kind of emotional energy release, or catharsis, in healing.
Approaches that
manipulate this kind of energy are almost unanimously rejected by most of
Western medicine, with the possible exception of acupuncture, a discipline still looked on with suspicion. Yet
the effectiveness of acupuncture has been clearly documented in numerous
studies, including one’s I myself have been involved in. Back in 1980. I did
some work with my husband Agu and Larry Ng, a Chinese psychiatrist and
neurologist in the Western tradition, which was published in Brain Research, showing
that acupuncture stops pain
by stimulating the release of endorphins into the cerebrospinal fluid. We were able to demonstrate that it was
indeed the flow of endorphins that caused the pain relief, because
when we used an endorphin antagonist (naloxone) to block the opiate receptors, the pain-relief
effects of acupuncture were reversed. As interesting as this work is, however,
it only begins to address the
manifold implications of the
psychosomatic network and its potential for
healing.
The body psychotherapists, people who know how to help us tap into this
network, are showing us many other uses for the “info-energy” that coordinates
all our systems. We need to listen to them, learn from them.
PLAY
I feel restored by
my rest—even energized—and lift myself off the sun- warmed concrete slab and
head back to the lecture hall to catch the last of the presentations. I arrive
to find that it is the closing session and the last speaker is winding down.
Soon, a playful group takes over the stage, singing, dancing, and playing
musical instruments, and there I spot my buddy Carl Simonton, who signals me to
join the crowd. I hesitate a minute, not quite sure whether such antics fit
with my scientist self-image, but I easily overcome my resistance and find
myself hopping up on stage, where I sway rhythmically with my fellow conferees.
It’s fun, its Disneyland, and I’m ready to get some quality stress- reduction
after my busy day. Rut play is more than simple stress-reduction. It serves an important function
in both animal and human life. We see this in
young animals who regularly engage
in mock battles
as an important part of their development. Like them, we can
use play in many ways—to act out our aggressions, fears, and griefs, to help us
gain mastery over these sometimes overwhelming emotions. When we are playing,
we are stretching our emotional expressive ranges, loosening up our biochemical
flow of information, getting unstuck, and healing our feelings.
Its play that
does it for me, lets me fully express myself and prevents me from taking myself
too seriously. And that’s what I do for the rest of the evening, greatly assisted in my effort to have fun
by Carl’s two young children, who are having the time of their lives with
Mickey and friends.
For one brief
evening, I too have been a child again. The thoughts of our business deals with
Peptide T are far behind me, and I put on hold all my anxieties about the outside evaluators coming to our lab, the
teenaged son who’s now too old to play with his mom, the necessity to play the
role of important scientist. I laughed, which Norman Cousins calls internal
jogging, an exercise to keep us in emotional shape, I played, I let the
emotions—and the peptides— flow.
There’s much
more to health than play and progesterone, of course. And achieving optimal
health involves more than just minimizing our drug
dependencies,
or maximizing our capacity for self-expression. The final chapter of the hook
and the Appendix explore many more of the ways you can put the practical
implications of my research to work in your lives.
13 TRUTH
WELLNESS
I’m circling
high above the General Mitchell Airport in Milwaukee, my plane preparing for
the descent. Looking out my window, I see the great plains of the Midwest
stretched out beneath me toward the horizon and, off to the left, a huge and glorious body of water, which, I’m surprised to learn, is Lake Michigan.
This
is the heartland, the geographical center of the country, and a psychological
center as well. Here folks don’t care much for extremes, showing little
interest in either the cerebral intensity of the East Coast or the laid-back,
touchy-freely attitude so prevalent on the West Coast.
My plane lands,
and after collecting my bags, I find my way to the prearranged meeting point
for my ride to northern Wisconsin. I’m glad to be here in the Midwest, to breathe in the fresh, sweet air and leave
the fast lane in
D.C. behind me, the current triumphs and frustrations
with Peptide T firmly in Michael’s hands for the time being. It’s the summer of
’96, and I have come to Wisconsin to present
at the Twenty-first Annual National
Wellness Conference.
The Wellness
Conference is the product of the “wellness movement,” a grass- roots effort
that took off back in the seventies when a group of exercise physiologists,
nutritionists, psychotherapists, an ex-priest, and an ex-nun found common
ground in their commitment to fitness and healthy lifestyles as the optimum route to disease
prevention. The movement
was the Midwest’s answer to
the alternative medicine/ consciousness movement originating at places like
Esalen on the West Coast, only minus the New Age patina. Although the initial
impetus was local, advocates of health and wellness from all across
the nation are now part of the effort,
coming together in a huge annual conference sponsored by the University of
Wisconsin every summer at its Stevens Point campus.
My first contact
with the wellness folks was in Ithaca, New York, a year earlier, when I was
invited to speak at one of their smaller events. I was impressed by how down-to-earth and relaxed the organizers were,
dressing in shorts and sneakers
instead of power suits and high heels, and providing plenty of
opportunities in between
the proceedings to party. I learned that their focus is
on
wellness as opposed to sickness, a concept that emphasizes the positive by
defining health as something more than the absence of illness. This is a trend
I’ve been encountering in many quarters, most recently when I ran across a
group of American chiropractors and nutritional biochemists who call their
approach “functional medicine” to emphasize optimal functioning of all organ
systems, rather than simply the absence of disease. For the wellness folks,
prevention—as in “an ounce of prevention is worth a pound of cure”—is a primary
focus. This leads them to promote self-care,
which requires patients to take increasing responsibility for their health by
making lifestyle choices that minimize or eliminate the use of drugs, alcohol,
and cigarettes, and promote behaviors that are life-enhancing.
As an outcome of this emphasis
on self-responsibility, the wellness
movement has spawned a team of “wellness consultants,” trained specialists who
go into major public and private corporations to design and implement on-site
health and fitness programs. The point is to help employees reduce stress and
improve health by making lifestyle changes, thus saving employers’ insurance
plans from the skyrocketing costs of cardiac operations and other dire medical
interventions. Here in the Midwest,
the wellness people are quietly
but effectively doing their part to change the face of health care and
medicine in America.
ENVIRONMENTAL MEDICINE
I’m met at the airport by Dr. Norman Schwartz, a doctor from Milwaukee
who has offered to drive me to Stevens Point,
some 200 miles north. Norm, whose specialty is environmental
medicine and who also has a degree in physics,
is one of the new breed of alternative or complementary M.D.S, the
midwestern counterpart of Bob Gottesman, who also treats his patients
with an understanding of the whole
bodymind. We met earlier this year in Arizona when I presented at a gathering of
physicians concerned with chemical sensitivity and diseases caused
by environmental factors.
Afterward, we talked
a few times on the phone, exchanging expertise
in our respective fields, and I was impressed
with his knowledge of nutrition and vitamin therapy. Many of his suggestions
sounded plausible, and so I decided to try some of them, making changes in my
diet and lifestyle, and self-monitoring for the results. Our long drive gives
us plenty of time to catch up, and I’m eager to hear the latest about
nutrition, the
environment, and the bodymind.
The last
time we talked, Norm was concerned about the impact of environmental pollutants
and toxins on people’s health, and, if anything, his concern has deepened. I’m
shocked when he reels off statistics indicating that cellular levels of heavy
metals and dioxins from herbicides and pesticides are 300 to 400 times greater than they were when first measured, and
every year, hundreds more chemicals are added to the 80 to 100,000 chemicals
that already exist in our environment.
I knew that
environmental pollutants could enter into the cell membrane and change the
shape of the receptor, making it looser and sloppier, and often wondered how this might affect the transfer of information so necessary to run
the delicately balanced systems. It had to have some effect on what is
essentially a
self-organizing system, one that is processing tremendous amounts of
information at incredibly rapid speeds.
Norm has his
own theory about how some very basic life processes are interrupted and altered
by these pollutants. He explains how electrons flowing— the classical
energy currency of all biological life-forms—through cell
membrane gradients is what normally allows the mitochondria, the energy-
generating component of cells, to transfer energy at about a 98 percent
efficiency rate. But the pollutants suspended in the cell membrane are altering
and interrupting that electron now, causing “energy starvation” and resulting
in conditions like chronic fatigue, allergies, and chemical sensitivity.
Particularly
alarming is Norms belief that accumulated environmental pollutants within our bodies are mimicking and disrupting the
action of our sex hormones—estrogen, progesterone, and testosterone—which run
the male and female reproductive systems. And he’s far from alone in this
belief—despite the medical establishments apparent lack of interest in the
subject, as exemplified by how little attention it has paid to the link between
toxicity and breast cancer. A recent report on receptor binding in Science, for example, has shown that
environmental toxins have estrogen like effects and bind to estrogen receptors,
where they can stimulate breast cancer tumor growth. Similarly, various toxins can act like testosterone in the male body
and stimulate prostate cancer, which is embryologically similar to breast
cancer. Although this has been suspected for a long time, only recently have we
gotten the hard proof that the accumulation of these toxins in our bodies
chronically stimulates our estrogen and testosterone receptors, putting them
into a state of overdrive and leading to cancer.
And as if this weren’t enough. Norm continues,
he believes it’s very probable
that increased
levels of environmental toxins are causing
our immune response to lose much of its resilience.
To be effective, the immune system needs to be in a state of constant readiness to fight off
the many viruses and other invading pathogens we encounter daily. When it’s
overloaded and diverted by high toxicity,
it gets “tired,” failing to stay on its feet, so to speak, which is possibly
why we’re seeing so much suboptimal health such as vague complaints of fatigue, not to mention more serious
immune-deficiency diseases.
As Norm
talks,I’m thinking of the biblical saying “As ye sow, so shall ye reap.” It is becoming apparent that people’s overall state of
health today is a direct reflection
of the ecological mess we’ve inflicted on our planet, a mess that has been created
in blind ignorance and disregard for what turns out to be the essential
relatedness of all life. How can we expect to be healthy when our water is foul, our air dirty, our food poisoned?
And it seems to me that much of the current disaster can be traced
to old-paradigm thinking,
which views each of us as an isolated
entity, separated from others and from our environment, living apart from the whole and not
connected to it. It is this erroneous belief that has permitted the poisoning of our environment through the development and careless manufacturing of toxic chemicals for farming and
industry. Fortunately, the new breed of M.D.S,
such as Norm Schwartz and Bob Gottesman, and doctor-friends such as Jim Gordon and Nancy Lonsdorf on the
East Coast, are taking seriously the fact that we are all part of the earth’s ecosystem, and they are willing
to look at what needs to be done to protect and cleanse our bodyminds in this
late-twentieth-century reality.
Norm is happy to
pass on some recommendations for ridding the system of toxins and maintaining a
relatively pollutant-free bodymind. To begin with, he tells me, high doses of
Vitamin C (1,000 mg. or more) should be a part of everyone’s basic nutritional
defense kit. He also has some simple rules for a healthy, pollution-free diet,
which include the following: Only eat food that has been around for at least
six thousand years—no processed foods! Don’t eat something if you can’t
pronounce the ingredients. Try to buy fruits and vegetables grown organically—or
even start your own garden! And stay away from
poultry, meat, and dairy that has been pumped full of antibiotics, a common practice in animal farming
today. Instead, choose products from animals allowed to graze
freely (“free-range”) and less susceptible to the diseases
antibiotics are used to prevent.
As part of his own practice, Norm offers a clinical test to measure
toxicity in the liver, the organ that acts as the initial filter to prevent harmful
substances from getting
to the bloodstream. If the liver
tests
as having high toxicity, he prescribes a variety of dietary, vitamin, and
herbal therapies that will help cleanse it and restore its full functioning.
I listen, but
I’m well aware that the establishment mocks the concept of detoxification and
makes no room in its offerings for nutritional and cleansing approaches. Where
I come from, the biomedical research community, these modalities are seen as
“fringe,” or irrelevant, for there has been very little good research done on
the subject. However, the results of several small but well- designed trials
showing the ability of nutritional supplements to support the liver for well-being and health have impressed me enough to experiment on myself.
I’ve
used liver vitamin products like Ultra-Clear, which work by altering the
chemical structure of toxins in the liver so that they can be excreted through
the urine or the large intestine. The results have convinced me that the
possibility of turning back the clock and increasing energy levels by removing
years of accumulated toxins is not “pie in the sky.” I only wish that there
were more studies, other than manufacturer-funded ones, in this very important
area. (Of course, the biggest liver-cleansing boost of all is to go off drugs,
including alcohol.)
As we pull into
Stevens Point, I am thinking about what special contribution I can make, based
on my research and theories on emotion and the psychosomatic network, to help
people achieve the goals of the wellness movement. I feel challenged: What is it that I in particular have to tell people about
wellness, about self-care and healthy lifestyles? A bodymind lifestyle
for the twenty-first century—what would that look like?
• • •
JOTTING DOWN some notes later that evening about
what I will tell people in my talk, I
imagine myself standing before my audience and confessing: “I’m from the sickness movement, the mainstream
biomedical establishment. We’re the people who do all the high-tech
interventions that are costing billions in insurance dollars while patients are
allowed to smoke and drink their way to the operating room and the
intensive-care unit.” I cringe at the thought.
While I don’t ally myself with
the disease-focus of the mainstream, people still tend to see me as a representative of it.
In mainstream
medicine, the importance of lifestyle in preventing disease is still largely
ignored in spite of inroads made by such heroic and outspoken doctors as Bernie
Siegel, Dean Ornish, Christiane Northrup, Larry Dossey, and Andrew Weil, to
mention just a few. A recent article in Parade
magazine made clear the party line. In “What Medicine
Will Conquer Next,” fourteen leading
biomedical researchers, many of them Nobel Prize winners, were asked to predict the advances they see occurring
in the next fifty years. What follows is a paean to the glories of high-tech,
high-cost modern medicine, with particularly glowing praise heaped on genetic
research as the answer to all our ills.
Noticeably
absent in the article is any reference to, or acknowledgment of, the necessity of people taking
responsibility for their
own health—until the very
end, when Dr. Bernadine Healy, former NIH Director and now a professor in the
medical department at Ohio State, gets the last word: “Changing your lifestyle
can make a difference. Genetics is a big factor in determining a person’s
susceptibility to disease, but a healthy lifestyle may be just as important.”
One lone female voice pointing to
what we all know to be true: The choices we make about how we live are at least
as valuable as the high-tech interventions of the biomedical
establishment—especially because they may minimize the need for such
interventions.
Part of the
reason that more lifestyle advice is not forthcoming from the laboratories is
that we scientists, in general, do not see our role as that of advice giver,
having been taught by our training that pure science is not necessarily
practical science. We tend to get uncomfortable when pressed to talk about how
to put the conclusions we draw from our research
into practice. I can’t deny that
I, too, would prefer to hide behind the laboratory door, tinkering away at my bench and letting
everyone make of my work what they will. Pure science! Isn’t that what I got
into it for? But something has happened to me along the way. The research I
have done has profoundly transformed me, letting me see what a healthy life looks
like from a perspective that was not available before I did my work. It is from this perspective, coming out of a radical,
transformative paradigm shift, that I wish to share some advice on
healthy living with my wellness
audience. I believe it’s a unique angle I offer, based on a new understanding
that can help us all to live happier and healthier lives, because it
acknowledges that the body and mind are not separate, but really one system
coordinated by the molecules of emotion.
LIFESTYLES OF THE HEALTHY, WHOLE, AND CONSCIOUS: AN
EIGHT-PART PROGRAM
For most of us, the very words healthy lifestyle
conjure up images of low-fat
meals,
daily exercise regimens, and the elimination of alcohol, tobacco, and
recreational drugs. While these are all good, health-enhancing strategies—and
I’ll have something to say about them from the point of view of the peptidergic
network—what’s missing for most of us is any focus on ongoing, daily, emotional
self-care. We tend to deal with the physical aspects of keeping ourselves
healthy and ignore the emotional dimension—our thoughts and feelings, even our
spirits, our souls. Yet, in light of the new knowledge about emotions and the
psychosomatic network, it’s obvious that they, too, are a part of our responsibility to manage our own
health.
The tendency to
ignore our emotions is oldthink, a
remnant of the still- reigning
paradigm that keeps us focused on the material level of health, the physicality
of it. But the emotions are a key element in self-care because they allow us to
enter into the bodymind’s conversation. By getting in touch with our emotions,
both by listening to them and by directing them through the psychosomatic
network, we gain access to the healing wisdom that is everyone’s natural
biological right.
And how do we do this? First by acknowledging and claiming all our
feelings, not just the so-called positive ones. Anger, grief, fear—these
emotional experiences are not negative in themselves; in fact, they are vital for our survival. We need anger to define
boundaries, grief to deal with our losses, and fear to protect ourselves
from danger. It’s only when these feelings
are denied, so that they
cannot be easily and rapidly processed through the system and released, that
the situation becomes toxic, as discussed earlier. And the more we deny them,
the greater the ultimate toxicity, which often takes the form of an explosive
release of pent-up emotion. That’s when emotion can be damaging to both oneself
and others, because its expression becomes overwhelming, sometimes even violent.
So my advice is
to express all of your feelings, regardless of whether you think they are acceptable, and then let
them go. Buddhists understand this when they talk about nongrasping, or
nonattachment to experience. By letting all emotions have their natural
release, the “bad” ones are transformed to “good” ones, and, in Buddhist terms,
we are then liberated from suffering. When your emotions are moving and your chemicals
flowing, you will experience feelings of
freedom, hopefulness, joy, because
you are in a healthy, “whole”
state.
The goal is to
keep information flowing, feedback systems working, and natural balance
maintained, all of which we can help to achieve by a conscious decision to enter into the bodyminds
conversation. I’d like to explore a number
of
different ways of using awareness and intention to tap into the psychosomatic
network, in order to prevent disease and maximize health.
One: Becoming Conscious
Most lifestyle choices involve
things we do or don’t do. But I’d like to
consider a choice that has more to do with being
than doing—after all, we are
human beings, not human doings—and this is the decision to
become more conscious. Full consciousness must involve awareness of not just
mental but emotional and even basic physical experiences as well. The more
conscious we are, the more we can
“listen in” on the conversation going on at autonomic or subconscious levels of
the bodymind, where basic functions such as breathing, digestion, immunity,
pain control, and blood flow are carried out. Only then can we enter into that conversation, using our
awareness to enhance the effectiveness of the autonomic system, where health
and disease are being determined minute by
minute.
Just how
powerful consciousness can be to intervening at the level of our molecules and making significant changes in our physiology was brought home to me by an encounter I had in 1986
at Lake Arrowhead, California. I was attending a conference of researchers in
the emerging field of PNI, organized by Norman Cousins, and was fortunate to
spend some time with Evelyn Silvers, the widow of Phil Silvers (of Sergeant Bilko fame). Evelyn had been a
practicing psychotherapist for years and had recently become so caught up in
PNI that she went back to UCLA to get her Ph.D. in a related field. She knew of
my work and had already sought me out on the East Coast a year before, arriving
in a limo at my
NIH office to take me and Michael out for lunch. I was fascinated to hear about her therapy, which combined
relaxation, autohypnosis, and visualization in a guided technique
to help a person direct her or his own healing. At Arrowhead,
I got to experience it. After a brief counseling session, in which I confided
about the stress I was experiencing in my efforts to develop Peptide T, she
said she thought I might benefit from an increase in my endorphin levels. She
offered to put me into a light trance, and we began a process of guided visualization.
“Which is the
most potent of the endorphins and where is it most highly concentrated?” Evelyn
asked, once I had relaxed into a pleasant altered state. I told her it was the
beta endorphin, which is found most abundantly in the pituitary gland.
“Good,” she
encouraged. “Now I want you to close your eyes and focus on your pituitary
gland. Do you know where it is?”
It took a few
moments, but I, of all people, knew exactly what to look for and had very little trouble
bringing the pituitary into sharp visual
focus. I nodded.
“Great, now can
you see the beta endorphin molecules in there?” she coached me further. The
beta endorphin was clear on my inner screen, all thirty-one of its amino acids strung together
in a bead chain and stored tightly
in tiny, balloon like pouches at the ends of the
cell axons, ready for launch.
She continued: “I want you to listen as I count backward from ten, and
when I get to one, you are going to release the endorphins out of your
pituitary into your bloodstream.”
I did exactly as
she directed and felt an instantaneous rush, a feeling that accompanied what I
knew was the outpouring of endorphins from my pituitary as they began swimming
and binding receptors all over my body and brain to work their magical effects.
It was clear that the knowledge I had of physiology—just where
the endorphins were located and how they were secreted—had enabled me to
consciously intervene and intentionally change my molecules. I wondered it this
same kind of knowledge could help others who might benefit from the release of
certain biochemicals in their systems.
Later I got a chance
to try that idea out on
a group of female heroin addicts at the Baltimore County Jail. Some of my
colleagues were running an experimental program there, which offered auricular
acupuncture—three needles in the ear a day—to alleviate the craving for heroin
and diminish the bodywide pain that makes withdrawal so difficult. The
researchers knew of my work showing how acupuncture stimulates the release of
endorphins to create analgesia (pain relief), so they invited me to come and
see their program at the jail.
My visit took place on Mother’s
Day, not a happy time for incarcerated women who were missing their
children as well as suffering from withdrawal. In simple terms, I explained to
them how they all had a natural form of heroin, the endorphins, in their brains and bodies,
and that as a result of continually shooting the artificial substance, the flow of the endorphins had been diminished. They found this an amazing
concept. I explained
that the craving they felt would cease when the natural flow of the chemical was restored, and that exercise and orgasm were two
means of enhancing that natural flow. Out of this discussion came a new way for
these women to think about their addiction. Although no longterm studies have
been done to explore how visualization to release endorphins might benefit drug
addicts, I saw in the faces of the women that
day that the very idea was empowering to them, giving them hope for an eventual healing
as well as a new respect for the powers
of their own bodies.
Two: Accessing the Psychosomatic Network
Because of my consciousness—awareness of the anatomy
and biochemistry
—I had been able to access my psychosomatic network and enter the bodymind’s conversation to redirect it.
The nodal point I used was the frontal cortex, a part of the brain that is rich
in peptides and receptors. Also known as the
forebrain, the frontal cortex is unique to humans and sits behind the forehead. It is the location for all the
higher cognitive functions, such as planning for the future,
making decisions, and formulating intentions to change
—which
is what I did, in the case of releasing the beta endorphin. In short, the
frontal cortex is what makes us truly human. Chimpanzees have 99 percent
of the same genetic material as we do, but lack a developed frontal
cortex. In humans, this part of the brain does not fully develop until some
time in the early twenties—a fact that helps us understand, and hopefully be more patient with, our teenagers!
Interestingly enough,
the frontal cortex
is just as dependent on the free flow
of the peptides of emotion through the psychosomatic network as any other part of the bodymind. In order to function at a
level that allows it to perform the kind of conscious intervention into the
bodymind’s conversation that I am talking about, the frontal cortex needs
adequate nourishment. The brains only food is glucose, which is carried to the
brain in the blood. It’s glucose that supports the ability of the neurons to store
and secrete all the messenger chemicals— neurotransmitters and
neuropeptides—and glucose that fuels the brain’s glial cells, which perform many essential functions. Acting as
“cleaner-up” cells, the glials are peptide factories that move around macrophagelike,
sometimes destroying and sometimes nurturing nerve endings in an ongoing
sculpting of connections, literally making up our minds. Only when there is
enough blood flow to bring plentiful
supplies of glucose to the brain will the neurons and glial cells be able to
carry on their functions and ensure full consciousness.
Blood flow is
closely regulated by emotional peptides, which signal receptors on blood vessel walls to constrict or
dilate, and so influence the amount and velocity of blood flowing through them
from moment to moment. For example, people turn “white
as a sheet” when they hear shocking
news, or “beet
red” when they become enraged. This is all part of the exquisite
responsiveness of our internal system. However,
if our emotions are blocked
due to denial, repression, or
trauma, then blood flow can become chronically constricted, depriving the
frontal cortex, as well as other organs, of vital nourishment. This can leave
you foggy and less alert, limited in your awareness and thus your ability to
intervene into the conversation of your bodymind, to make decisions that change
physiology or behavior. As a result, you may become
stuck—unable to respond
freshly
to the world around you, repeating old patterns of behavior and feeling that
are responses to an outdated knowledge base.
By learning to
bring your awareness to past experiences and conditioning— memories stored in
the very receptors of your cells—you can release yourself from these
blocks, this “stuckness.” But if the blockages are of very long
standing, you may need help in achieving such awareness, help that may come in
many different forms. I would include among them psychological counseling
(hopefully, with some kind of touch!), hypnotherapy, touch therapies, personal-
growth seminars, meditation, and prayer. Any or all of these can teach you to
respond to what is actually occurring in the present, which is in large part
what consciousness is all about.
Three: Tapping into Your Dreams
One of the best ways I know to
integrate awareness of emotions into lifestyle
is to develop the daily habit of recalling and transcribing your
nighttime dreams. Dreams are direct messages from your bodymind, giving you
valuable information about what’s going on physiologically as well as emotionally.
Becoming
aware of your dreams is a way of eavesdropping on the conversation that is
going on between psyche and soma, body and mind of accessing levels
of consciousness that are normally beyond awareness. This allows you to get
valuable information and then, if necessary, to intervene, making appropriate
changes in your behavior and your physiology.
What is happening
when you dream? Different parts of your bodymind are exchanging information,
the content of which reaches your awareness as a story, complete with plot and
characters drawn in the language of your everyday consciousness. On a
physiological level, the psychosomatic network is returning itself each night
for the next day. Shifts are occurring in feedback loops as peptides spill out into the system (in greater
or lesser numbers) and bind to receptors to cause
activities necessary for homeostasis, or return
to normalcy.
Information about these readjustment enters your
consciousness in the form of a dream, and since these are the biochemicals of
emotion, that dream has not only content but feeling as well.
We have seen how
strong emotions that are not processed thoroughly are stored at the cellular
level. At night, some of this stored information is released and allowed to
bubble up into consciousness as a dream. Capturing that dream and
reexperiencing the emotions can be very healing as you either integrate the
information for growth or decide to take actions toward forgiveness and letting
go.
Classically,
Freudian psychology uses dream analysis to help people understand motives, desires,
behavior: “Aha, you dreamt you killed your mother? Must mean you’re harboring
resentment that you haven’t admitted—the source of your neurosis!” But from the
bodymind viewpoint, your dreams can relate not just to your mind but to your
body as well. Dreams can be your own early-warning system, letting you know if
a medical condition is developing and helping to bring your conscious attention
to the problem area. The body may be discussing this condition with the mind, and you can get in on the conversation by consciously recalling the
dream. Although it’s hard to translate such a conversation for anybody else—to
say that the dream of an army invading means that a cancer is growing or some
arbitrary equivalency like that—I can tell
you that once you make the decision
to pay attention to your dreams, they will start to
speak to you, and you will understand them with ever-greater fluency over time,
with practice.
I have been
writing my dreams down in a notebook for years. I started during the period
when I didn’t have a laboratory, while Peptide T was awaiting further
development and Peptide
Design had been disbanded, and I think my
unconscious motivation was that I could use myself as a laboratory (as I also
did with meditation). Some of my most valuable insights leading to growth are
the results of dreams I recalled during that time. The pivotal dream I had of
Sol, in 1986, in which I threw
water on him and he shrank up—my nemesis, the monster I myself had created—gave me
the courage to write him a letter of forgiveness that allowed me to let go of
resentments that had been eating away at me for years.
I keep my
dreambook the way I keep a laboratory notebook, writing the narrative content
on the right-hand page, when I usually record the steps of a lab procedure, and
the emotional content on the left-hand page, when I usually jot down
calculations and comments. The bodymind is a laboratory for each of us in which
we are all participating scientists, seeking to better understand and affect
behavior and physiology. In this way, we are all seekers of the truth! Just as
the bench scientist does when evaluating a series of experiments, you may want
to review a particular dream at a later
time to see what kinds
of emotions were being processed. The review process
may reveal patterns that add to your awareness.
I often hear people say, “I can’t remember my dreams,” as if they were
helpless to initiate this process. But that is the crucial first step, the
simple decision to remember your dreams, which
the frontal cortex of your
brain
enables you to do. From that decision all else will follow. Once you have decided, prepare yourself by placing a pen and notebook by your bedside. Deepak Chopra talks about intention and attention in Seven Spiritual
Laws, and this is a perfect illustration of what he means. The intention is
the decision to capture the dream in writing, the attention is the focus, the
readiness to carry out the action created by intention, in this case, writing
down the dream! By consciously applying your attention and intention in this
way, you will be able to cultivate the habit of recalling your dreams and gain
greater access to your bodyminds information system.
When you wake in the morning,
stretch, yawn, and reach for your
dreambook. Write whatever comes to mind, no matter how fragmentary, and try not to filter or edit any of the content. If associations arise—Aha! That
yellow car is the same one my dad had when I was ten!—write them in parentheses.
Even more important than the content, however, are the
feelings and emotions you experienced in the dream. Always ask: How did I feel?
And include these observations in the writing. Sometimes the emotions are
contrary to the action, such as
dreaming about a tragedy and feeling happy. The
feeling is the clue.
Even
if the feelings are disturbing or uncomfortable, force yourself to write them
down. This is good practice for becoming more aware of both your waking
emotions and those you experience in a dream, and to become less judgmental of
your own inner processes.
Write down
dreams that you recall only partially, too. When I first started my dreambook.
I would often have just a glimmer to write about, but I found that if I wrote
even the tiniest fragment, it started a process of deeper recall, oftentimes
bringing back the dream in its entirety. Be sure to write down even the most
insignificant-appearing dreams, because
by discounting a dream that seems dull or
boring, you may be preventing yourself from getting
an important message.
Often the apparent banality is only a mask for material
that you are resisting because of its disturbing or discomforting content. Once
you write down the boring part, other parts will surface into memory.
Like our
emotions and thoughts, our dreams follow the laws of information, existing on a
level that is beyond time and space. Many tribal peoples recognize this and
credit their dreams as coming from the spirit world, treating them with utmost
respect. While Jung’s collective unconsciousness is as close as we come to such a belief in our own culture, we
can put information theory and ancient wisdom together and start giving more
validity to dreams as a low-cost, no-drug form
of psychotherapy. If we are looking for some practical, low-tech self-care
on our journey to wellness, dream work can make a tremendous contribution.
In my more
mystical moments, I like to consider that dreams are just one more way God
whispers in our ear, delivering messages to us via the psychosomatic network.
Four: Getting in Touch with Your Body
But lest we get too
philosophical, I want to return to the level of the physical body and how through
it we can access the mind and emotions for wellness.
Dream
work and other forms of conscious intervention are important, but we
need to acknowledge other places of access as well—the
skin, the spinal cord,
the organs, which are all nodal points of entry into the psychosomatic network. As such, they are all
used by the touch therapies that have grown out of alternative medicine: Epstein’s network spinal analysis,
Bainbridge-Cohen’s mindbody centering, the synergism of Illana Rubenfield,
Lowen’s bioenergetics, the new identity
process, and massage.
I highly recommend these and other forms of body work that use
movement or touch to heal emotions. (See the Appendix for more information on
such therapies.)
But you can also do much simpler forms of body work to equally good effect.
Feeling low and sluggish? Take a walk.
Feeling anxious and jittery? Run! Feeling worthless? Get a massage, a
spinal adjustment, or a lot of good hugging, and see what happens. Your mind,
your feelings are in your body, and it’s there, in your somatic experience, that feeling is healed.
Five: Reducing Stress
No discussion
of lifestyles and wellness would be complete without mentioning stress-reduction. In my experience, the most elective
method for reducing stress is meditation, because it allows us, even without
conscious awareness, to release emotions that are stuck in modes that subvert a
healthy mindbody flow of biochemicals. I believe all forms of meditation are
useful, but the one I have personally used is transcendental meditation, or TM.
TM requires sitting in a comfortable position with the eyes closed twice a day
for twenty minutes while silently repeating the same word, called a mantra. The
teaching and
practice of TM have been standardized and many scientific studies show strong
evidence of physical benefits such as lowering high blood pressure, reversing autoimmune diseases, and stimulating a wide range of antiaging effects.
Another form of
meditation that is gaining popularity is “mindfulness.” as introduced by
psychologist/researcher Jon Kabat-Zinn of the Medical Center Stress Reduction
Clinic at the University of Massachusetts. This simple method
is
based on an Eastern technique known in Buddhist tradition as vipassana, in which you simply bring
your attention to your breath, sitting or lying down, eyes open or closed. By
breathing consciously in this way, you enter the mindbody conversation without
judgments or opinions, releasing peptide messenger molecules from the hindbrain
to regulate breathing
while unifying all systems.
Studies
have shown that mindfulness meditation can dramatically reduce pain and improve
mood for people who live with chronic pain by allowing them to exist in the
present moment rather than in the constant fear that their pain is “killing”
them. With this different awareness, they can carry on daily activities despite
discomfort. Kabat-Zinn’s approach is presented in his books Full Catastrophe Living and Wherever You Go, There You Are.
An easy way to
sample the benefits of meditation is by listening to any of the many “relaxation music” audio tapes available, some of which use guided imagery to help you project your consciousness into your psychosomatic network through programmed
affirmations, or positive statements, about health, prosperity, relationships, etc. Some
use Eastern terms or instruments, while others have unassuming titles like “A Trip to the Beach”
or “A Walk in the Forest.” I have found
that when I listen to the music and the words, the pattern of my breathing shifts and becomes
deeper, slower, bringing
about a profound sense of relaxation. I have
several tapes that are so deeply relaxing, I’ve yet to listen to them all the
way through without falling asleep.) Interestingly, these changes are not just
short-term. My experience indicates that this kind of relaxation can bring about a basic reconditioning of my breathing
patterns, so that even when I am not listening to a tape, my breathing
tends to be more
relaxed, freer.
For some,
meditation provides a direct link with the spiritual world, but practitioners
need not have this as their goal to benefit. Perhaps the key mechanism of meditation is that of simply
being in the present for a period of time. Shifting
the mind from shoulda, coulda, woulda types of thinking
promotes self-regulation and healing on all levels. In the race of modern life,
we all tend to adjust our sails
far too frequently, running
this way and that, always
in a hurry, not pausing long enough to see the effect of our trimming
on the course of our lives. Meditation provides an opportunity to stop
and wait for some feedback before
charging ahead on an uninformed course, a chance
to let the body catch up with the powerful transforming effects of our
natural information flow.
A simpler, less formal practice than meditation, but equally effective
at stress
reduction,
is the habit of self-honesty. By self-honesty, I mean being true to yourself,
keeping your word to others as well as to yourself, living in a state of
personal integrity. There
is a profound physiological reason
why honesty is stress-reducing. We have seen how the
emotions bring the whole body into a single
purpose, integrating systems and coordinating mental processes
and biology to create behavior. Walking is an example: You have a thought or
intention, which is then coordinated with the physiology to produce a behavior,
walking. If I have a purpose, such as finding a cure for cancer, then every
system in my body gets behind that
intention and does what needs to be done, be it increasing my appetite for protein, mobilizing my gastrointestinal system to
digest a protein better, sending blood flow into digestive organs to produce
necessary enzymes for maximum absorption, or whatever. There is a physiological
integrity and directness about this process that is the result of my clarity
about my own intentions. When I am at cross-purposes, however, going through
the motions but not really committed to my goal, saying one thing and doing another,
then my emotions
are confused, I suffer a lack of integrity, and my physiologic integrity is likewise
altered. The result can be a weakened, disturbed psychosomatic network, leading to stress
and eventually to illness.
Always tell the truth.
I have said repeatedly to my children
for years, not just
that it’s the moral thing to do, but because it will keep you on a healthy path
and disease-free! My friend Maggie McClure, a practicing spinal-analysis chiropractor, puts it this way: “I never
tell a lie, because it takes too much energy
to keep everything straight—energy I’d rather
use doing other things!” Honesty, it seems, is supported by our
biochemicals, and it only slows us down to choose otherwise.
One last word about stress: Play! Having fun is the cheapest, easiest,
and most effective way I know to instantly reduce stress and rejuvenate
mind, body, and spirit. The source of most people’s ongoing, daily stress, I
believe, is the perception of isolation and alienation, being cut off from the
company of others. Engaging in play is the antidote because it gets our
emotions flowing, and our emotions are what connect us, give us a sense of
unity a feeling that we are part of
something greater than our small and separate egos.
With this new
understanding of the importance of consciousness, emotions, and blood flow, we
can look at exercise and diet in a new way.
Six: Exercising
For the vast majority of us still
mired in old-paradigm thinking, exercise is drudgery, something we do in fits
and starts by motivating our
“physical
machine”
in a carrot-and-stick fashion for such benefits as a slimmer figure or harder
muscles. But with our new concept of ourselves as emotion-laden information
systems, exercise can be easier and more fun. Whenever I exercise, I always try
to engage my emotions by putting on a headset and listening to my favorite rock
tunes. Walking is a breeze this way, as the music helps to loosen up stuck emotions
and puts me move in touch with my body so I can “hear” what it is telling me to do. This way I don’t
push myself beyond
my capacity to a
possible injury or give up prematurely because of missing important feedback
about how good it feels to work muscle and bone. This is valuable information that encourages me to keep going—the difference that makes the difference!
I’ve learned
a couple of tricks to help me move my body in a way that helps to enhance the communication flow
throughout the bodymind. For example, I let the opposite hand swing forward
with each step as I walk, without music this time. Somehow this sets left brain-right brain
information flowing, breaking up old patterns
of worry and rumination. I’ve found that it’s impossible to stay stuck in unproductive old thought patterns
when I move my body this way.
Remember—the
value of exercise has less to do with building muscles or burning calories than
it has to do with getting your heart to pump faster and more efficiently and
thereby increase blood flow to nourish and cleanse your brain and all your
organs. Of course, if you exercise hard enough to break a sweat, you’ll also
get the benefit of a mood improvement prompted by the release of endorphins
(and other as-yetto-be-discovered peptides).
Yoga is a
particularly health-enhancing form of exercise. Any kind of conscious breathing accompanied by
relaxation and body awareness is yoga. But the best way of learning yoga, if
you are unfamiliar with it, is through classes— often at the local YMCA these
days!—or through numerous tapes and books available at local bookstores.
My own favorite
style of yoga is to use conscious breathing as I engage in well-defined rhythmic movements and postures, such as those
I use in walking or
swimming. To experience the power of this when you walk or swim, try breathing
in on two counts and breathing out on four, or whatever ratio of in-to- out breath
feels comfortable. Just make sure you double
the beats on exhaling
and stay in this rhythm for ten minutes, if you can. The effect is one of
increased energy and good feeling, both elements that reflect the good work I’m
doing and make it enjoyable to keep going.
Seven: Eating Wisely
Diet is another lifestyle
area that can be reframed
in light of our
understanding of the emotions.
Eating, because
of its survival value, has been wisely
designed by evolution to be a highly emotional event.
(All processes that impact on survival—sex, eating,
breathing, etc.—are highly regulated by neuropeptides, and thus are emotionally
directed. The simple emotions of pain and pleasure, signaling us to move either
toward something or away from it, have been key determinants in whether an animal or human survives
and evolves.) Our large and small
intestines are densely lined with neuropeptides and receptors, all busily exchanging information laden with
emotional content, which is perhaps what we experience when we say we have a
“gut feeling.” There are at least twenty different emotion-laden peptides
released by the pancreas to regulate the assimilation and storage of nutrients,
all earning information about satiety and hunger. Too often, however, we ignore
that information, eating when we’re not really hungry, using food to bury
unpleasant emotions. Nervous eating, depression eating—these are the resultant
behaviors.
By tuning
into your emotions
as information about
your digestive process, you can develop your ability to
know what your body needs in the way of nourishment and when. Remember, it’s
the peptides that mediate satiety and hunger, and we can’t hear what our
peptides are telling us when we are disconnected from, or in denial about, our
emotions. Ask yourself: Do I feel hungry?—and wait for a feeling of hunger to
occur before eating. A great idea I learned from the Hindu Ayurvedic tradition
is to slowly sip hot water, which will satisfy any false hunger and help
excrete partially digested food. If you are really hungry, however, it will
prepare the body to digest a meal completely.
We are all made
frantic by the continually changing advice from the nutrition gurus. While I
don’t advocate disregarding basic nutritional principles, I am calling for more reliance on the wisdom of
the body when making eating decisions.
A craving for something sweet may be a signal that your brain needs fuel, so
bite into a piece of fruit; a desire for a hamburger may be telling you that
your body needs more protein, so add more animal and/or soy products to your
diet. The benefits that come from eating according to your feelings—not your
impulses—are greater than any particular food rules you may be following to build muscle or lose weight. If impulses
dominate you, therapies that get at the source of the emotions involved, like
the body psychotherapies (see Chapter 11), can be effective in putting you back in touch with honest,
reliable emotions.
The environment
in which you eat has a lot to do with your emotional experience at mealtimes. I try always to eat in a peaceful stress-free environment
and
enjoy good company. Eating while emotionally upset or rushed can be very
detrimental to the peptide-regulated process of digestion. The thoughts and
feelings you bring with you to the table are just as important as the sensible
balanced meal you sit down to. Are you worried, tense, thinking about the grocery bill or the calories or the
toxicity levels? Are you scarfing down each bite
as if your meal might disappear at any moment? Or perhaps you “go unconscious”
when you eat, leaning over a newspaper or sitting in front of the boob tube
while you mindlessly shovel food into your mouth. This is a kind of disintegration,
a mindbody split that will lead to weight gain and disease conditions caused
according to Ayurvedic tradition, which I believe to be scientifically valid by
incomplete digestion.
Come into full
consciousness as you eat and feel thankful for your food, savoring its tastes
and textures. Blessing your food doesn’t have to be a religions ritual. It can
be as simple as saying: “Mmmm, this is good for me. I’m grateful. I’m
nourished.” I do this even when I “slip” and have a chocolate-chip cookie or two,
because I know that the emotion that accompanies eating is as vital an
ingredient as the vitamins and minerals in the food.
And a word about
sugar. I consider sugar to be a drug, a highly purified plant product that can become addictive. The body naturally
produces sugar in the
form of glucose, which is the only fuel the brain needs to function. We have
seen how the chemicals of emotion regulate blood flow to bring nourishment to
the brain, but our emotions and their corresponding chemicals also control the
availability of glucose. In states of high excitement, such as panic or
hysteria, the liver metabolizes glycogen, the form in which glucose is stored,
and releases it into the bloodstream where it is transported to the brain, making us alert to handle an emergency if need be.
Relying on an
artificial form of glucose—sugar—to give us quick pick-me-up is analogous to, if not as dangerous
as, shooting heroin.
The artificial substance is utilized by the body in the
same way as the natural form, but, like a drug, it floods and desensitizes
receptors, thereby interfering in the feedback loops that regulate the availability of instant energy,
such as glycogen
release from the liver. Over eons of time, our bodymind
has evolved a system for supplying the brain with the fuel it needs, and we
would be wise to respect it.
Eight: Avoiding Substance
Abuse
For the same
reasons that it’s best to avoid overconsuming sugar, I want to warn against the dangers of alcohol, tobacco,
marijuana, cocaine, and other
drugs. All of these substances have natural analogs
circulating in our blood, each
of which binds to its very own receptor
bodywide. Alcohol, for example, binds to the GABA receptor complex, which
also accommodates Valium and Librium, common prescription drugs for quelling
anxiety, providing an antianxiety effect, but only in the short run. When we
ingest these exogenous ligands, they compete with the natural chemicals that
were meant to bind with the GABA receptors, oftentimes flooding them and
thereby causing them to decrease in sensitivity and/or number. The receptors
then signal a decrease in peptide secretions, as I explained in my talk to the women heroin
addicts in prison.
All drugs can alter
the natural flow of your own feel-good peptides, and so, biochemically, there is
no difference between legal and illegal ones: They are
all potentially harmful, they can
all be abused, and they can all contribute to suboptimal health in one form or another, including chronic
depression.
When multiple
drugs are taken, such as when a person is smoking marijuana regularly and taking antidepressants—a common situation that is often missed
by the prescribing doctor—their side effects interact, and natural feedback
loops of the system can collapse, leaving only a small number active.
The good news is that the physiological effects
resulting from substance abuse are reversible: The heroin
addict can be cured, the chronic pot smoker can kick the habit, those who think
life wouldn’t be worth living without antidepressants may find that they have
healed sufficiently to do without them. But
it can be a very slow and sometimes painful process before the receptors return to their original sensitivity and
number and the corresponding peptides get back
into bodywide production and flow. In recovery, what is often
overlooked is that many systems—gastrointestinal, immune, and endocrine
to name a few— have been affected, not just the brain. Drugs put a tremendous
strain on the liver, the organ responsible for providing enzymes to metabolize
the drugs and dispose of their toxic
waste products. While the liver
is thus overburdened and distracted, toxicity from other sources builds up,
predisposing the bodymind to disease. Recovery programs, both formal ones and
those we institute for ourselves,
need to take into account this multi-system reality by emphasizing nutritional
support and exercise. Eating fresh, unprocessed foods, preferably organic
vegetables, and engaging in mild exercise like walking to increase blood flow
through the liver can speed the process up.
What causes
people to consume legal and illegal drugs—one of the central problems in our
society. I believe—is emotions that are unhealed, cut off, not processed and
integrated or released. Trauma and stress continually lodged at the level of
the receptor block nerve pathways and interrupt the smooth flow of information chemicals, a physiological condition we
experience as stuck or
unhealed
emotions: chronic sadness, fear, frustration, anger. Reaching for that drink or
cigarette or joint is usually precipitated by some disturbing and unacceptable
feeling that we don’t know how to deal with, and so we get rid of it in ways we know “work.” The frustrated
cigarette smoker, the depressed alcohol drinker, the hyper marijuana smoker—what if we stopped and checked in with
our feelings to ask ourselves what emotions are present before using an
artificial substance to alter our mood? If we can bring this level of awareness
to our habitual use of substances, then we
have a chance, a possibility, of making another choice. By continually
ignoring feelings, we have none. Perhaps we’ll find that it’s a matter of a communication that
needs to happen, a feeling that needs to be expressed, a need satisfied, a problem solved—all potential actions to
get our own endogenous juices flowing for a natural, peptidergic “feel good”
state. Or it could simply be that movement, in the form of exercise or a walk, could shift our mood.
CONNECTION
I’m jotting
these thoughts into a rough outline for my talk the next day when I’m
interrupted by the ringing of the phone. It’s Naomi Judd welcoming me to the Wellness Conference and inviting me to
join her and a few other presenters on
a panel she will moderate the next morning.
The immensely
popular country western singer, who with her daughter Wynonna toured
as the Judds, has been traveling in my circles
lately. Now retired from the
stage, she found a new interest, psychoneuroimmunology and alternative
therapies, which was spurred by a diagnosis of life-threatening hepatitis. In the
last few years, she has turned from the country circuit to what might seem to
be its diametrical opposite, the alternative healing circuit, which I call
complementary medicine. Like me, Naomi straddles two very different worlds, standing on a bridge between the
two, and I feel a sense of camaraderie with her because of this. The fact that
we were mothers before the age of twenty and had to struggle to raise children
while achieving success in our respective fields is a further
bond between us. We met once before,
when she had invited
me to dinner at an earlier wellness conference. She had exhausted all
traditional approaches to curing her condition and, having heard of my work,
hoped I might help her to understand her illness from a mindbody
point of view. Sometime
later, she sent me an autographed copy of her book, Love Can Build a Bridge, in
which
she mentions me and my work. As I read her book, I was touched by her life as a mother and a performer, but what really impressed me was that here was a person who was genuinely living her spiritual beliefs, using them to heal herself and heal her family.
“So I’m all
ready with a talk about wellness and lifestyles,” I tell Naomi, after a brief, friendly,
personal update.
“Well, of course
we all want to hear that,” she says enthusiastically. “But I’ve got something
else up my sleeve, something I think you’ll be just as interested in!” And then, not
skipping a beat:“I think what people really want to hear about is how we bring spirituality into the
mindbody question. Now, don’t you think that’s so?”
“Well, sure” I
hesitate. Naomi is pushing the edge. Scientists don’t talk about spirituality
publicly, and even though I’m considered something of a revolutionary, I still consider myself a mainstream scientist
and feel uncomfortable
talking spirit and metaphysics, even to the holistic crowd. But the
opportunity, at the same time, intrigues me. I have certainly thought a lot
about how spirit plays into the mindbody equation, and have even been able to
see how the science I’ve done could support this idea.
“Good, then
you’ll tell all those people how God has been found alive and well in your
laboratory, and that He’s really gonna heal us through those neuropeptides?”
she jokes.
If only it were
that simple, I think. “I’ll do my best,” I finally tell her. “But you’re going
to have to help out, Naomi. I’m a scientist, not a guru … It makes me very
nervous …”
“Oh, shucks,
Candace, they’ll love anything you say,” she shoots back.
We hang up
and I return to my outline. But it’s late, and I’m more in the mood to relax and call it a night. I wonder what I’ll say tomorrow
on the panel. It occurs to me that I’ve been interested in the role of
spirit—consciousness, the soul, the psyche—my entire life, ever since I was a
young child growing up in a mixed-marriage family and wondering what religion I
was.
The wellness
crowd may be getting a surprise tomorrow. I muse as I drift off to sleep. I am ready for a new level if
uninhibited expression. The panel moderated by Naomi Judd might be the perfect
place to formalize my understanding of how spirituality fits into the bodymind
picture, and to deliver a radical new message from the laboratories of
mainstream science.
SPIRITUAL HEALING
The Wellness
Conference events for the day are to be held in the campus fieldhouse, a
structure more suitable for holding athletic events than for showcasing presenters of the latest
update on health
and wellness. But the
climate is casual, and the sawdust on the floor is a reminder that folks here
don’t get out too far ahead of themselves. I report to a large room just off
the main stadium for the 10 A.M. panel and take my place on a raised platform
with the other panel members. The room is packed with what looks to me to be
about five hundred people.
Moderating a panel for the first
time. Naomi is in her glory, a sincere and gracious performer, perfectly at
home with her audience and exuding country charm. She opens the session and
introduces the panelists. Dr. Brian Luke Seaward. David Lee, Elaine Sullivan, and
myself, the first three as mindbody advocates who have been advancing wellness
in their multiple roles as psychotherapists, lecturers, consultants,
counselors, and authors, and me as the token scientist. The introductions are
long and laudatory, crammed full of details obviously taken off our CVs and prepared with an eye to public
relations, making us all appear highly significant and our work
remarkable. During the introduction, Naomi, in earnest comments that she fully
expects me to win the Nobel Prize in biochemistry one day. But when Naomi comes
to herself, she jokes. “Oh, just skip
it!” The audience loves her humility, and it’s no secret that Naomi is the draw
for this event, the one everyone has come to hear.
“Me, I’m just the
goofiest woman in country music,” is about all she’ll say by way of
self-introduction. “I’m enjoying being here with my girlfriends. Candace and
Elaine, and with you boys, Brian and Dave,” she says, her southern twang giving
away her Kentucky roots. Striking the broadest, most inclusive note, she
begins: “I think one of the most powerful things we do here at the Wellness
Conference is offer an opportunity for community. Like the feeling
I get from my congregation or my friends in country music. It’s the
unity and support I feel here, being with y’all” We all feel warmed, somehow
included—although a few audience members seem to be wondering if perhaps they’re
in for a revival rather
than a wellness panel.
“I’ve got
questions here.” Naomi shifts abruptly, adjusting her reading glasses in readiness to tend to the business
at hand. She refers to a list of questions
she has prepared for the panel, intending to get the conversational juices flowing
before opening
up the discussion to a general Q&A
from the audience.
“But first, did anybody see the issue of Time magazine that came out a few weeks ago?” Naomi flashes the magazine for all to see, the cover
picture depicting an angelic-looking modern-day creature, with the words “Faith
in Healing—Can Spirituality Promote Health” printed below it. I’d read the
article and was reminded of a similar article in Newsweek in 1988, in which my colleagues and I we’re interviewed
about the possible spiritual implications of the latest PNI research. While now I was pleased
to see some national recognition of this theme, back then I was horrified at the sight
of the four-letter word “soul”
in such close company with my own comments
about science and medicine.
“It amazed me that in this entire article, there was not one mention of
the greatest faith healer of all time, Jesus Christ,” Naomi is saying. “So the
first question I’d like to put to our panel is: Why is the spiritual aspect of
healing sometimes overlooked in mindbody health?”
Elaine gets the
first chance to respond and goes right to the heart of Naomi’s question.
“We rarely talk
about spirituality in mindbody health because it’s too difficult to describe and more difficult to
research. In addition, people equate spirituality with religion, which often
divides us and brings up strong disagreement. In contrast, I believe
spirituality is about a deeper search for meaning in our lives, and brings us together in a commonality of
purpose—however each of us finds that. I believe that spirituality is coming
full force into our culture because we all know that unless we tap into this deeper
strength and community, we won’t make it on
this planet.”
David Lee is
next: “Within the past ten years, there’s been a shift in psychotherapy, and
therapists have begun to realize that psychology is not big enough—there’s so
much more to human experience. It’s been slow, but we are gradually integrating
spirituality into the practice of psychology”
He pauses,
and I take a turn:
“My feeling is that there
is no scientific reason to
leave spirituality out of medicine. It’s a habit that our culture has gotten
into ever since the seventeenth-century philosopher René Descartes declared
body and soul to
be distinct, separate entities, entirely unrelated to each other. But the truth
that I have learned through my own late-twentieth-century science is that the soul, mind, and emotions do play an
important role in health. What we need is a larger biomedical science to reintegrate what
was taken out three hundred years ago.”
Naomi is beaming the audience is applauding. I’m feeling pleased with
myself for using my status as a member of the mainstream medical
community to advance the bodymind movement just a little further, when
suddenly I hear Naomi divulging a bit of personal historyémy own. “Candace is a
basic scientist who sings in a church choir,” she says. “Do you want to tell
them all how that came about?”
A little
uncomfortable to be suddenly so intimate with my audience, I nonetheless try my
best to answer. “Yes, I belonged to the Methodist Church choir for years, having joined when I came to a place in my
personal journey where I was unable to forgive someone who I felt had betrayed
me deeply. The music of the Christian church drew me in, and I started
attending services and singing in the choir. I heard sermons about the teachings
of Christ, which I’d never been
exposed to before, and especially clear was the message of forgiveness. I was beginning to let go of
my grievances, and I sought out other approaches to heal myself as
well—meditation, dream work, massage therapy to bring about a healing of my
past experience. Forgiveness is a key Christian concept, but it is also a key
bodymind concept.”
Was I really
saying this? A little part of my mind is surprised, but it feels right to be
integrating my personal life with my science—even in public!
Brian takes my
lead: “What I think we’re talking about here is love. All healers—the shamans,
the wisdom keepers—tell you they’re tapping into a higher source of energy they
call love, and that they are sharing this love with whomever they’re healing.
JesusÙ message was about love and compassion,
both of which follow forgiveness. And I agree with Candace and Elaine
that these elements need to be included in our Western medical mindframe. I see
a growing grass-roots movement aimed at bringing spirituality back into
healing. This is reflected in the huge increase in the number of people turning
to alternative therapies, many of which speak to spiritual as well as physical
and emotional issues. People are saying enough!—we’re
tired of the body-is-a- machine approach, and we want to get back to the
original equation.”
“Brian,” Naomi
interrupts. “I read in your new book that eighty percent of illness and disease
is caused by stress, and I’ve heard it said before that stress is a condition that results
from spiritual isolation. What do you have to say about that? Are we really
separated from God and our soulfulness by modern technology and materialism.”
“Yes, Naomi, I
believe that stress is a disconnection from our divine source— or, more
accurately, the perception that we
are separated, because the truth is we’re
really always connected. At times, though, we forget
and don’t feel
connected
to our source. One reason for this is we are so cut off from nature in our
society. I think the closest some people get to the outdoors is the Discovery Channel!”
“We are
certainly spiritual beings in a physical body and not the other way around,”
Naomi comments, her country western accent an anomaly in such New Age-speak.
“Now, another question: How can we best communicate for healing at the mindbody
level.”
David picks this
one up: “The approach that I’ve been trained in, traditional talk therapy,
doesn’t seem to impact the mindbody level. We often hear our patients say, ‘I
know I shouldn’t feel this way, but I do!’
Knowing something doesn’t always impact how we feel, and we may have to get
past purely verbal communication to access our emotions. Some of the approaches
I have found effective at getting to deeper, more fundamental levels are
storytelling, hypnotherapy, neurolinguistic programming, and any of the
expressive therapies that employ visualization, music, and art. In the past,
these kinds of therapies were thought
of as alternative approaches, but now we’re seeing them included more as complementary approaches. Very shortly, I believe we’ll
be calling them integral
approaches, indicating that they are completely integrated into the mainstream.”
Naomi turns to
Elaine: “Elaine, how can healers and helpers use this new mindbody research?”
“Well, a
technique I use with my clients is journal-writing, because it helps them to
give a literal structure to their internal world. Writing gives us an awareness
of what our patterns are so we can change them if necessary. Studies have shown that when trauma victims
write about their
experiences, physiological changes occur, such as increased blood flow
and a boost for the immune system that can last for up to six months. Also,
I recommend meditation. When I heard Dr. Larry Dossey say that a half hour of meditation was as powerful a
stress-reliever as a hall hour of jogging. I was greatly relieved, because I’m
not a jogger!”
I can hold back no longer:
“I certainly agree with both Elaine
and David, but an element I think we are skipping in our discussion of
practical applications for mindbody health is body work: the touch therapies of
massage, chiropractic, and any other modality that includes the body as a means
of healing the mind and emotions. It’s true, we do store some memory in the
brain, but by far, the deeper, older messages are stored in the body and must be accessed
through the body.
Your body is your subconscious mind, and you can’t heal it by talk alone”
There is a
thoughtful pause, until Naomi cracks, “Well, I saw a few mouths drop open on
that one!”
“But it’s true”
Brian reflects, and then poetically: “The body becomes the battlefield for the
war games of the mind. All the unresolved thoughts and emotions, the negativity
we hold on to, shows up in the body and makes us sick. Forgiveness is about
opening up the heart and learning to love, which is why I think we’re all here on this planet. So simple, yet such a difficult lesson to learn”
“Absolutely”
Naomi says, “and I found that out through a therapy I utilize called network
spinal analysis. It was started
in New York about fifteen
years ago, by a man named Dr. Donald Epstein. It works by using very
gentle manipulations to remove interference from the nervous
system. As you all know, I have a chronic illness. Wynonna
had a ruptured disc, Ashley has sinusitis, and
we all use network for these things”
Naomi turns
toward the panel and reads another question. “Explain subtle energy and subtle
anatomy, including the human energy field or aura, chakras and meridians. How does all of this fit into the mindbody
healing formula?”
Brian is ready
with a response: “I believe subtle energy is a kind of universal life force
that flows through us from the divine. According to Eastern wisdom, everyone
has an aura, a field of this energy surrounding the physical body, and flowing
through it as well, traveling along lines called meridians by the Chinese or
radiating out from the seven body centers
called chakras by the practitioners of yoga. Westerners even
have a version of it in Christianity, as the halo surrounding the crown of the
head, often depicted on saints and angels in medieval art. But you
don’t have to be a saint, an angel, or a yogi to acknowledge this subtle energy. It’s in everyone and can be a force for healing”
Yes, I’m
thinking, but the church certainly co-opted that one over the centuries, making it
the singular province of holy men and divine
beings.
“There’s a
wonderful book called Vibrational
Medicine by Richard Gerber, which describes different modalities of
mindbody energy healing, ranging from therapeutic touch and massage to mental
imagery and subtle energy” he concludes.
“Candace” I’m called back by the sound of Naomi’s voice. “You’ve been
awfully quiet during this discussion. What do the scientists say about all this
subtle energy stuff?”
“As you know,
Naomi,” I begin, “I’ve spent a good part of my professional life trying to integrate these Eastern
ideas with science. One thing I can tell you, you won’t find anything
about chakras in a biology
textbook! For me the key
concept
is that the emotions exist in the body as informational chemicals, the
neuropeptides and receptors, and they also exist in another realm, the one we
experience as feeling, inspiration, love—beyond the physical. The emotions
move back and forth, flowing freely between both places, and, in that sense,
they connect the physical and nonphysical. Perhaps this is the same thing that
Eastern healers call the subtle energy,
or prana—the circulation of emotional and spiritual information throughout the
bodymind. We know that the way health occurs in the physical body has to do
with the flow of the biochemicals of emotion. My work has taught me that there is a physical reality to the emotions.”
“And how true
that is,” Naomi says, addressing the crowd in her matter-of- fact, down-home
manner. “I’ve known this all along, and so have most of you. Before I was a
country western star, I was a nurse, and I could always tell which patients were going to get better
and which weren’t
by seeing who would laugh at
my corny jokes!
But I want to show you all an example
of bodymind unity.
And to do that, I need a volunteer from the
audience—someone I can pick on,” she says mischievously, and then lights on a
young man from the front row. He looks confused as she beckons him to come
up on the panel platform.
“Good! You’re
squirming already!” Naomi says playfully. “Now I’m going to ask you a question:
How many guys does it take to change the toilet paper roll?” The young man, at
a loss for words, smiles awkwardly and looks at his feet. “I don’t know,” Naomi
shoots back after a pause. “It’s never happened!” The audience lets out a roar,
but Naomi interrupts to make her point: “Now look how he is blushing, I want you all to see. His face is red as a
beet!” She puts her arms around his shoulders
and gives him a good-natured hug, thanking him as she sends him hack to his seat.
“Candace, I
have just put your entire life’s work into a single joke. A thought started in
that young man’s mind and instantaneously it was translated into a physical
reality. He turned bright red with embarrassment! Now there’s your
neuropeptides at work, for all to see!”
Naomi has
certainly done it translated my research in such a simple, graphic way that
everyone could get it. I’m grateful for her unabashedly frank demonstration,
her ability to convey in simple, everyday terms what I can only speak about
medically, philosophically.
She continues. “Now we’ve known all along
about this. But we needed the research for the validation. And that’s what I’m so grateful to you for Candace.”
Now it’s my turn to blush,
as all eyes are on me. But it’s true that this has
been the role I’ve been able to play in recent years—saying that many alternative
medical
approaches have validity equal to that of establishment medicine—and I’m
grateful to have been given this opportunity. Thanking Naomi, I begin to
address the crowd.
“It’s a fact
that healing approaches that incorporate emotional and spiritual elements have
been around for years, in one form or another. But the mainstream has treated
them like poor stepchildren and relegated them to the fringes of alternative
medicine. The argument that they are untested and therefore can’t be taken
seriously, is not valid. So much of mainstream medicine itself is totally
unproven—yet we do it anyway. I’m afraid that we are holding the alternative
therapies, those that use mindbody and spiritual techniques, to a higher
standard than we apply to mainstream medicine. And, furthermore, just because
we may not understand the mechanism of a particular technique, that shouldn’t necessarily stop people from
using it. For thousands of years, we’ve known that when you’re sick, you need
bed rest and warmth, and yet this advice has never been studied or published in
a medical journal. Every once in a while a piece of folk wisdom does get tested. We now know, for example,
that chicken soup really does have therapeutic effects for the common cold! I guess
what I’m saying is—learn to
trust yourself.”
Naomi begins to wrap it up. “I’d like the panel to discuss
this one last question before I turn the mike over
to the floor and take questions from the audience” she announces. “How can we
reconcile religion and such healing processes as yoga, meditation, biofeedback,
aromatherapy? I myself am a practicing charismatic Pentecostalist, the Middle American,
flag-waving girl next door,
and I have people ask me all the time, ‘Naomi, how can you sit on the advisory
board for Deepak Chopra’s institute and then go on Christian talk-radio shows?
How can you go to church and then go home to meditate or do yoga?’ Elaine,
you’re an ex-nun, so I’d like to give that one to you”
“Yes, Naomi,
you’re so right,” Elaine begins. “There is a lot of confusion out there, and I
think it stems from fear and misunderstanding. It all goes back to the mindbody
split, which, as Candace has pointed out, is an arbitrary division that current
research has shown once and for all to be invalid. We have learned to distrust
our bodies and our feelings, to place our trust in outer authorities instead of our own inner power. I find that meditation
in no way contradicts my faith, because there are many routes to the spirit”
The discussion
that follows is lively and to the point. Naomi was right, people are eager to
explore the role of spirituality in healing, even here in the Midwest, where I
would have thought it was too controversial, too woo-woo, too
Californoid.
The panel discussion has been an
incredible experience, giving me the chance to
synthesize all of my ideas about spirit, the emotions, and science, and leaving
me with a profound understanding of my own transformation. Most amazing is that all of this was catalyzed by my new
girlfriend, Naomi Judd, who is not a scientist, not a mystic, but the
down-home, country western sweetheart of whitebread America! Getting to know
Naomi has made me feel a sense of deep connectedness and unity that is
unquestionably spiritual. Her simple message of healing through spirit embraces
all my science, making it easy for everyone to understand.
HOLY SPIRIT
The next day I
catch a predawn prop plane out of Milwaukee back to Washington, D.C. As the
small craft inches through the pink and purple sky, I watch from my tiny window
as the growing light slowly obscures Venus, the morning star. Suddenly, the
round disk of the sun looms over the horizon and the colors fade, transforming
the sky into a flood of soft blue.
I can’t stop
thinking about how brilliantly—and simply—Naomi illustrated the principle of the mind becoming matter,
preceding matter, organizing matter, by singling out the young man in our audience
and planting a thought in his
mind that made him blush. Thoughts and emotions came first, and the peptides
followed, causing the blood vessels in his face to open. As Deepak’s sages in
India understood, the non-stuff, the “nothing,” is the source; and the stuff,
the material phenomenon, manifests from there.
This is such a fundamental shift for the Western mind, but
one that science can help us
understand. Originally, we scientists thought that the flow of neuropeptides
and receptors was being directed from centers in the brain—the frontal cortex,
the hypothalamus, the amygdala. This fit our reductionist model, supporting the
view that thoughts and feelings are products of neuronal activity, and that the
brain was the prime mover, the seat of consciousness. Then, as a result of my own and other
peoples work in the laboratory we found that the
flow of chemicals arose from many sites in the different systems
simultaneously
—the
immune, the nervous, the endocrine, and the gastrointestinal—and that these
sites formed nodal points on a vast superhighway of internal information
exchange taking place on a molecular level.
We then had to consider
a system
with
intelligence diffused throughout, rather than a one-way operation adhering
strictly to the laws of cause and effect, as was previously thought when we
believed that the brain ruled over all.
So, if the flow
of our molecules is not directed by the brain, and the brain is just another nodal
point in the network, then we must ask—Where does the intelligence, the information
that runs our bodymind, come from? We know that information has an infinite
capability to expand and increase,
and that it is
beyond time and place, matter and energy. Therefore, it cannot belong to the
material world we apprehend with our senses, but must belong to its own realm,
one that we can experience as emotion, the mind, the spirit—an inforealm! This is the term I prefer, because it
has a scientific ring to it, but others mean the same thing when they say field
of intelligence, innate intelligence, the wisdom of the body. Still others call
it God.
Although it’s a
simple concept, it’s hard for the Western mind to understand. But I recall one
person who was able to grasp it instantly, a cameraman working on the set of Bill Moyers’s PBS special Healing and the Mind. As I was groping to explain how the
innate intelligence, generated by subtle energies from flowing biochemicals, all converged in the inforealm, what came out was puzzling
to Bill, but not to the cameraman. When the taping was over and everyone
was packing up, the gentle, soft-spoken man approached me and said, almost
whispering it in my ear, “You were talking about
the Holy Spirit,
weren’t you”
Feeling a bit embarrassed, I had to admit that, yes, maybe I was.
Reductionists will always argue
that the molecules come first, are the primal force, and that thoughts and
emotions follow as a kind of epiphenomena of the molecules. And they’ve got
good evidence: Doesn’t the flow of peptides change
the physiologic responses, which then create the feelings we experience?
Doesn’t
the chemical release of endorphins cause the
feeling of pain relief or the euphoria of runner’s high?
I don’t deny
this, but what I’m saying is that we must recognize that there is a two-way
system of communication at work. Yes, the release of endorphins can cause pain
relief and euphoria. But, conversely, we can bring about the release of
endorphins through our state of mind, as I experienced so vividly when working
with Evelyn Silvers. I like to think of mental phenomena as messengers bringing
information and intelligence from the nonphysical world to the body, where they
manifest via their physical substrate, the
neuropeptides and their receptors.
HOME
I’m happy to be
back in my office at Georgetown University Medical School, where both Michael
and I now hold positions as research professors, and where we are able to continue our research on
Peptide T and its effects on gp120 and AIDS virus. It’s a spiritual place with
a legacy, Georgetown, founded by the Jesuits
in the eighteenth century, and I am comfortable here because it is a setting that reflects my current state
of bodymind: mainstream, decidedly, but with
an added dimension of the spiritual.
I have been
talking with Father Sweeney about infusing holistic approaches into the medical
school hospital, bringing the mind/body/spirit reality into the medical setting
and setting the Georgetown hospital
apart from others with an apt slogan—“The whole person comes
first” This could be a boost to the ailing financial status of the hospital,
which has suffered from the influx of HMOs and from other difficulties that are
part of the current health care scene. I suggest to Father Sweeney that
hospitals have to be competitive these days, to offer something unique to gain
the competitive edge. Holistic, whole,
healthy, and holy—all words
stemming from the same root, the Saxon hal,
and all linked in meaning. The Jesuits
are a holy order, so it makes sense for them to be part of
the holistic movement.
The spiritual
viewpoint, Father Sweeney tells me, confirming my feeling about the religious aspect of holism, is
one that sees the unity of all things, that allows us to experience our oneness
with all others and with God. I can understand this on a scientific level: Yes,
we have a biochemical psychosomatic network run by intelligence, an
intelligence that has no bounds and that is not owned by any individual but
shared among all of us in a bigger network, the macrocosm to our microcosm, the
“big psychosomatic network in the sky” And in
this greater network of all humanity, all life, we are each of us an individual
nodal point, each an access point into a larger intelligence, it is this shared
connection that gives us our most profound sense of spirituality, making us
feel connected whole.
As above, so
below. To think otherwise is to suffer, to experience the stresses of
separation from our source, from our true union. And what is it that flows
between us all, linking and communicating, coordinating and integrating our many points? The emotions! The emotions
are the connectors, flowing between individuals, moving among us as empathy,
compassion, sorrow, and joy. I
believe
that the receptors on our cells even vibrate in response to extracorporeal
peptide reaching, a phenomenom that is analogous
to the strings of a resting
violin responding when another violins strings are played. We call this emotional resonance, and it is a scientific fact that we can feel what others feel. The oneness of all life is based on this
simple reality: Our molecules of emotions are
all vibrating together.
This is where I
have come to in my personal life, to an acceptance of my part in the bigger
play, and an awareness of how in science, we are all working together to bring about the truth.
Now it turns out that Peptide T is not just part of the latest efforts to cure AIDS,
but a possible broad-spectrum antiviral drug
that shows remarkable results in many other chronic
conditions as well. This
new application is based on the discovers that the virus acts at an additional
receptor other than the T4, a “coreceptor” called the chemokine receptor, and it is a discovery made by the very
researchers I believed were trying to stop me
from developing Peptide T as an AIDS drug. Now they welcome me as I
return to the
fold, and I feel the forces of synergy and cooperation at work in the universe.
I’m relaxing
with these thoughts in the familiar comfort of my office, still small but not
as tiny as that early cubicle I inhabited at the Palace, the one Biff Bunney
entered to console me in a much darker hour. It’s an attractive space,
decorated with my favorite rainbow art, one wall covered with photos and
mementos given to me by people I have met over the years. A large bulletin board frames
my “famous-person montage,” where I’ve arranged the photographs I’ve collected of myself
with various public figures. One shows me with the Pope, who granted me an
audience when I presented at a conference in Rome in 1985. The Pope! How strange—my work here at Georgetown is to
bring forth the new paradigm, integrating the new with the old, and the Pope
watches from my office wall, this time in alliance with me, not Descartes!
Suddenly
I remember that I have a new photo, one of Naomi and me taken at Stevens Point,
and I pull it from my briefcase to place it in my gallery alongside the Holy
Father.
As I admire the
new addition to my collection, my eye is caught by the colorful rug hanging on the adjacent wall. My mystical rug, I
call it, because the design has mystical overtones: a dawning sun surrounded by
yellow sunflowers and large black birds. But its real significance is that it
first appeared to me in a dream the night before I left for a gathering
sponsored by Brigham Young University—The Psychobiology of Health and Wellness,
a Conference on
Healing
and the Mind—which was held in 1995 in Provo, Utah. I dreamt I was on my way to some very important place, to
make a presentation perhaps, when suddenly I realized I was completely naked. I
was feeling very frightened and dejected, as if I’d been cast out into the
wilderness with no protection, when, magically, as if from thin air, a rug
appeared and wrapped itself around me. I immediately felt better, my confidence
and sense of purpose restored as I continued on my journey in my new cloak.
When I awoke, I could make no sense of the dream but recorded it anyway.
The next day I
was in Provo, where I gave my usual talk for a group that had been hosting
mindbody health meetings for the past twelve years, presenting an assortment of
speakers from backgrounds in spirituality and psychology. Joining me on the
roster was Bob Ader of early PNI fame, the two of us representing the
organizers’ first attempt at bringing some hard science into their program. The
audience, largely made up of Mormons, was quite serious, and even though they
barely laughed at my many jokes, I liked these very healthy and hardy-looking
people whose ancestors had forged
the early Church
of the Latter Day Saints.
While
I knew very little about their religion, I could tell they were survivors,
coming from a stock of tough pioneers whose lives were guided by spirit, and
for this I admired them.
After the
sessions ended, all the speakers shared an exquisite walk in the surrounding
mountains, led by a group of elder churchmen, and I had a chance to interact
more closely with some of them. My talk had caused quite a stir, it seemed, not only for the science I had
presented, but also because I had talked about
the role of the emotions, mind, and spirit
in health and how I had come to
an understanding of these elements in my own life. This is what had fascinated
them, they told me, the idea of a person who had been transformed by her work,
who had come to a spiritual place from scientific truth-seeking. I thanked
them for their flattering words, and later,
in my room that night,
thought about how true I felt this to be.
The next morning, I was driven
to the airport by one of the younger
Mormons. After I had checked
my bags and we were saying good-bye, he handed me a large package and explained shyly that the
conference sponsors had wanted me to have it as a token of their appreciation.
I unwrapped it right there, and literally got chills all over my body as I
recognized it as the rug from my dream of a few nights before.
This was my new mantle,
the symbol of my
spiritual transformation through scientific truth-seeking, which the Mormons
had somehow recognized.
When I’d returned from Provo, I brought the rug into my new office at
Georgetown, intending
to spruce up the empty room with some personal touches. It remained on the
floor until one day I decided to hang it on the wall where I could see it
better. Now it serves as a daily visual reminder of my purpose here at Georgetown, symbol of the role I aspire to play
as truth-seeking scientist and catalyst in the mindbodyspirit revolution in
modern medical science,
It is an honor and a gift I will never forget.
SCIENCE: THE SEARCH FOR TRUTH
For me, science
has been a quest to understand nature—both human and Mother. As I have known it
in its purest, most exalted form, science is the search for truth. It was this belief that drew me to science,
and through all my
naivete and despite all my many false
turns, it’s what has kept me on the journey.
The heart of
science is feminine. In its essence, science has very little to do with
competition, control, separation—all qualities that have come to be associated
with science in its male-dominated, twentieth-century form. The science I have come to know and love is unifying,
spontaneous, intuitive, caring
—a process more akin to surrender
than to domination.
I have come to believe that science, at its very core, is a spiritual
endeavor.
Some of my best
insights have come to me through what I can only call a mystical process. Its like having God whisper in your ear, which
is exactly what happened on Maui when I stood up with a slide of the HIV
receptor in the brain and suggested a new therapy for AIDS, only to hear an
inner voice say to me: “You should do
this!”
It’s this inner
voice that we scientists must come to trust. We must stop worshiping a
dispassionate “truth” and expecting the experts to lead us to it. There’s a
higher intelligence, one that comes to us via our very molecules and results from our participation in a system
far greater than the small, circumscribed one we call “ego,” the world we receive from our five senses
alone. New understanding from quantum
physics and information theory points us away from the cool, detached, solitary genius, the one who has the answers
that others don’t have, as if the
truth could be owned, and toward a
more collegial, participatory model of knowledge acquisition. The rational,
masculine, materialistic world we live in places too much value on competition
and aggression. Science at its most exalted is a truth-seeking endeavor, which
encompasses the values of cooperation and communication, based on trust—
trust in ourselves and in one another.
EPILOGUE: PEPTIDE T—THE STORY CONTINUES
MICHAEL AND I call it “Peptide T weather”—ice
storms, heat waves, hurricanes passing close or hitting hard, shutting down
electricity and closing roads. Whenever our research takes a pivotal turn, it
seems, meteorological aberrations abound. Rainbows, too, have appeared as
mystical heralds announcing crucial moments in our Peptide T adventures—Maui,
Puerto Rico, Provincetown.
So, it’s no
surprise to either of us, in September of 1996, to be caught in the worst local
flood of the century on our way to Baltimore for Dr. Robert Callo’s annual AIDS
meeting. The Potomac River is overflowing its banks as a result of the combined
rains of hurricanes Fran and Hortense, making freeway travel all but impossible. As might be expected, we
are late for this fifth day of a week- long meeting
in which promising
new AIDS research
has been the focus,
research that we hope will be the beginning of a full vindication of our claims
about Peptide T.
We arrive soggy
but spirited at the hotel in downtown Baltimore. A directory in the lobby tells us where to go for the
talk we have come to hear: “New Concepts
in Immuno-Pathogenesis of AIDS.” We race off to join our colleagues in hopes of learning more about a
development that was first reported in the New
York Times a few months earlier, causing quite a stir at the midsummer
International AIDS conference in Vancouver.
The big news is
that there has been a shift in attention by the mainstream AIDS researchers
away from the HIV virus itself and toward the cells that the virus attacks—in
particular, a certain protein studding the surface of most immune cells. It is
this protein, a peptide receptor, that has been discovered as a new mechanism
by which the virus enters the immune cells.
Scientists have
been fighting for a decade about how the virus actually kills T4 cells: Does the virus enter the cell
and kill it by literally imploding within it,
or does another, more indirect mechanism cause the disease, that of
apoptosis, a programmed cell death? And then there’s the theory of Candace and
Michael with their child of the new
paradigm—no longer a radical theory—which says
it’s not the virus itself
that causes the damage, but the blocking
of the receptor by the gp120 viral fragments, and the resulting denial of access to the cell by
natural
peptides vital for cell and whole organism functioning and health. One thing we
all agree on now—the T4 (CD4) receptor on the immune cell is necessary, but not
sufficient, for the HIV virus to enter the cell.
Now, in this
latest development, it had been found that a new receptor, the chemokine receptor, was part of this process.
Five major labs had made headlines by simultaneously reporting
that the HIV virus was using not only the previously understood mechanism of the T4 (CD4) receptor
to enter cells, but
one of the chemokine receptors
as well, now considered a “co-receptor.” The labs had elegantly demonstrated that
both receptors were required for the virus to enter the cell, working together
as a kind of double-docking system.
Gallo and his
team were acknowledged extravagantly for doing the seminal work that led to the
finding. As part of their ongoing research, they had been following up on an
observation made by researchers that some patients infected with the virus
remained healthy for years, seemingly impervious to the infection in spite of continued exposure. Dr. Jay
Levy of the University of California at San
Francisco had shown that the immune cells of these long-term survivors secreted
a substance that seemed to block the virus from entering the cell, but because
the molecular structure of the active ingredient had never been cracked, it had been difficult
to make much progress.
With the help of
his team, particularly Tony deVeco, Gallo was able to isolate the activity
from the immune
cells of long-term survivors, then crack the
structure of the factor, only to find it had been discovered before as a
peptide ligand for chemokine receptors. The focus on chemokines had already
heated up when they were observed to mediate inflammation, a key process in
many diseases from Alzheimer’s to psoriasis. Now, with its newly realized
relevance to AIDS, this field was about to become positively scorching!
Epidemiologists
had shown that a small percentage of people who lack the chemokine receptor
(due to a rare genetic mutation) never got AIDS, no matter what high-risk
behavior they indulged
in. Bingo! This was the solid clinical proof in favor of the theory
that the chemokine receptor is not just another heartbreaking laboratory
artifact, but instead, a viable vulnerable spot in the virus’s life cycle. In its absence, the virus is prevented from
entering the cell and causing the symptoms of AIDS. Clearly the race is on to
find new receptor blockers as the next generation of anti-AIDS drugs.
When I’d heard
the news back in June, I went straight to the library and quickly compared the
peptide sequences of the various relevant chemokines with that of Peptide T. I was thrilled to find out that there was a possible match.
Could
Peptide T, invented six years before the term chemokine was even coined, be an
antagonist to the chemokine receptor? In a synchronicity almost beyond belief,
we learned that the key activity test for putative chemokines was the very
chemotaxis assay that Michael and I had used to link mind and immunity fourteen years ago!
Over the course
of the Gallo meeting in Baltimore, my colleagues have been approaching me,
asking in half teasing, half dead-serious tones: “Do you think Peptide T binds
to the chemokine receptor?” I field their inquiries cautiously and keep my lip
zipped, refusing to say a word. A bit wiser from my experience, I’m content to wait until a ton of data is available
to make an iron-clad case for what I believe will be a positive answer.
After all, Michael has the pivotal assays up and running at our Georgetown lab, the crucial
chemotaxis assays, which will soon
give us the data to know for sure.
THE FACE OF AIDS has changed. Thank God for the protease
inhibitors! At last there is
an effective long-term treatment for AIDS. The new protease inhibitors, when
started in a cocktail with the older anti-virals (which slows the onset of drug
resistance) is enabling people to live longer. Invented by scientists at several companies, the drugs were
rapidly and efficiently tested and approved with lots of AIDS activist-inspired
cooperation.
But sadly,
unexpected trouble is appearing a year or two after treatment in the
three-quarters that can tolerate the “triple drug cocktail.” Despite the many
effective treatments doctors devised for preventing, diagnosing, and treating
opportunistic infections, patients still never regain all the weight they lost
during their last infection. About a quarter of the long-term AIDS survivors
are steadily losing weight—muscle mass—and the data show they will die with
“wasting” when their weight falls to 65 percent of normal. During all this
suffering, their virus levels often remain so low as to be undetectable.
Is gp120 causing
AIDS symptoms like wasting? Gp120 is so potent that just a few cells infected
with viruses resistant to the new powerful anti-viral cocktails could secrete
enough gp120 to poison several kinds of peptide receptors. It is so potent that
an assay to routinely measure the tiny but damaging levels of gp120 found in
HIV-infected patients hasn’t yet been found. Scientists believe infected
cells—which secrete gp120—lurking in “sanctuaries.” Sanctuaries include places like the brain into which the current
drugs penetrate poorly.
Neuro-AIDS is also on the rise, another black cloud, along with wasting,
on the horizon of the relatively brighter picture of AIDS we see today.
URGENCY quickens the pace of our Georgetown team … still further. Other
scientists
in the physiology department, experts in wasting and neuropeptide receptors,
are now working on Peptide T as a gp120 antagonist. Now, we must compile our
findings to present as impeccable scientific papers. Our presentations at meetings have been helpful.
They have allowed us to hone the meaning of our data and hear suggestions of
experiments necessary to fill the gaps. But talks at meetings are merely
published as “abstracts”—only the publication of full reports in scientific
journals will be considered to provide the solid scientific rationale needed to
expand human testing of Peptide T.
Growth hormone,
which promotes lean muscle mass and testable strength performance, is the only
therapy even provisionally approved for AIDS wasting. Gp120 injected
into the brains of rats produces weight loss! Peptide
T restores the secretion of
growth hormone to rat pituitary gland cells, which has been reduced by gp120.
These experiments had been started two years ago when our chairman at Georgetown, noticing
a peptide sequence
homology between Peptide T and a peptide which
releases growth hormone,
had invited us to join the department.
We’ve handed
off the chemokine peptides to Doug Brenneman’s NIH team for collaborative experiments—they protect against
gp120 neuronal cell death
just like VIP and Peptide
T! Chemokine receptors
are on brain as well as
immune cells where gp120 binding must certainly contribute to Neuro-AIDS and
other inflammatory brain diseases.
Now we’ve got
the chemotaxis data that show Peptide T is a chemokine receptor antagonist. To
complete the story, we need to get the Peptide T receptor binding assay to work
so we can see if it can be displaced by chemokines, as predicted. With yet
another eerie synchronicity, we’ve learned that chemokine receptors, VIP
receptors, and growth-hormone-releasing hormone receptors are all from the same
biochemical family—the one to which the opiate receptor belongs! So far I can’t
get a signal, but I should be able to figure out how to get that binding assay
to work. We need to get those papers out.
While we focus
on our daily experiments in the lab, we are awaiting further results of Peptide
T clinical trials for Neuro-AIDS with great hope and prayer. Hard as it is to
do a simple one-day lab experiment perfectly, the ethical issues central to
experiments with human beings and the resources such experiments demand
intensify the difficulties enormously. But despite their difficulty, I believe only scientifically sound human
trials can teach us the potential of Peptide
T—or any other drug or mind-body treatment for that matter. In the end all the rosy anecdotes
and uncontrolled data are almost worthless. Last week we
heard
that some renowned AIDS clinicians will recommend that Peptide T be added to
some NIH trials. We need more trials. We need more good science. We need to get
those papers out. We push on.
We can hardly
believe that it’s been over ten years on this AIDS project. It seems only to
get richer and more interesting as it continues to unfold, now coming forward
into receptor-based treatments, where we started. Now nearly everybody wants to
know what part of gp120 binds to the chemokine receptor, what peptide sequence
will block it.
Hold on to your
horses, this Peptide T baby is about to bolt. It’s very much a time of renewed
focus and determination. All sorts of very smart, well-funded labs are taking up these questions. The
scientific understanding of AIDS is truly leading to a new understanding—with
new strategies for curing—of many other diseases. Mike and I, at times, smile
knowingly at each other, sharing feelings that
are somewhat like those we have for our young but suddenly mature daughter,
who graduated from college last week. Childhood ends, and so begins
a new phase, with all its risks and hopes.
APPENDIX A
PREVENTION-ORIENTED TIPS FOR HEALTHFUL, BLISSFUL
LIVING
We must take
responsibility for the way we feel. The notion that others can make us feel
good or bad is untrue. Consciously or—more frequently— unconsciously, we are
choosing how we feel at every single moment. The external world is in so many ways a mirror of our beliefs and
expectations. Why we feel the way we feel is the result of the symphony and
harmony of our own molecules of emotion that affect every aspect of our
physiology, producing blissful good health or miserable disease.
We have the
hubris to think that just because we invented electric lightbulbs, we can keep any hours we want. But
neuropeptide informational substances link our biological clocks to the motions
of the planets, which is why your quality of sleep—and wakefulness—is likely to
improve the more closely your retiring and your rising are linked
to darkness and daylight. If you get to sleep
between 10 and 11 P.M.,
most of you will be able to wake up naturally and rested with the sunrise, if
not before.
Meditation
practiced early morning and early evening, routinely, even religiously, is, I
believe, the single quickest, easiest, shortest, and cheapest route to feeling good, which means being in sync
with your natural feelings.
The early morning
is a great time to enjoy, to consciously envision a wonderful day. It’s a great time for the conscious mind to
reenter the body with bodyplay (exercise sounds dreary), which may be gentle
stretching or yoga one day, a brisk walk with dancing or a run to break a sweat
the next. See how you feel before you decide. It seems natural—what the body
was designed to do—to move a bit on arising, before eating or climbing into a
car. Our foremothers and forefathers would almost certainly have started their
days with movement.
For those of you
interested in weight loss, another reason to get moving early on is that we are designed to be able to
turn on the fat-burning neuropeptide circuitry
in our bodyminds with just twenty minutes of mild aerobic
exercise at the beginning of the day. Research by exercise physiologists has
shown that after twenty minutes of elevated heartbeat and the deeper,
more frequent breathing that naturally comes with it, our bodyminds enter
a smooth, fat-burning mode
that
lasts for hours. The alert and calm feeling that settles in after an initial
feeling of exhilaration usually
goes hand in hand with a reduced
appetite.
Spend some time
in nature every day, longer on days off. Being outside is being in nature
regardless of whether
you’re in a forest, at the beach,
or downtown in a large city. Look at the sky! Even cities have skies
over them. Bad weather is no excuse—invest in warm clothes,
good shoes, and a waterproof outer layer.
When to eat is
as important as what you eat. Don’t starve yourself all day and eat late. In
fact, your biggest food intake should be your midday meal, as it is in every
nonindustrial culture, and as it used to be in our own. Eating at midday allows the food plenty
of time to be completely and wholesomely digested before you retire for the evening.
It also means
that the molecules of nutrition will be
carried to sites in the bodymind where they will reinforce conscious, vigorous,
waking activity rather than being deposited as fat, which happens more readily
when we eat too late. If you’ve never observed such a schedule, you may be amazed at the jolt of mental and
physical energy you will feel—which is the way you are supposed to feel.
Avoid exogenous
ligands that perturb
the psychosomatic network
so much that they warp its
smooth information flow, producing “stuck” information circuits that prevent you from experiencing your full repertoire
of potential experiences, and instead cultivate feedback loops that restore and
maintain your natural bliss. Translation: To feel as good as possible all of
the time, avoid doing drugs, legal or illegal. Question any chronic
prescription: If you have to have it, make sure you are taking the lowest
possible dose that does the job. Under the supervision of your doctor or other
medical consultant, consider taking a “drug holiday” every once in a while to
see if you really still need that sleeping pill, antidepressant, antiulcer, or
high blood pressure medication. Experience how amazingly responsive and resilient, lively and blissful
the natural undrugged state is. Being drug-free
allows your system to focus on healing your own bodymind rather than
compensating for drug-induced alterations and expending bodymind effort on
detoxifying and excreting drugs.
Think of sugar
as a drug with chronic effects right up there with more acknowledged “drugs of
abuse.” Sucrose, the white powder isolated from acres of green plants
(sugarcane or sugar beets) turns into glucose, a key metabolic regulator of
your bodymind, which acts on glucose receptors to control the release of
insulin and numerous other neuropeptides from the pancreas, drastically altering
how we feel—sluggish or peppy,
low or high—and how we
metabolize
our food. Satisfy sweet cravings with fruit, which has a different kind of
sugar, fructose, which less readily causes the release of insulin. Refined
white sugar changes the profile of peptides released from the pancreas (in
addition to insulin), which results in a sluggish, fat-storing mode. In
general, work on exploring the impact of what you eat on the way you feel.
Drink eight
glasses of unchlorinated water every day. So often we eat when we’re really
thirsty rather than hungry. Our internal signals have gotten confused because
we evolved eating whole, natural foods (fruits and vegetables), which have a much higher water content than our
current diets of chips and dips and numerous other packaged, processed foods
and junkstuffs.
Aim for
emotional wholeness. When you’re upset or feeling sick, try to get to the
bottom of your feelings. Figure out what’s really eating you. Always tell the
truth to yourself. Find appropriate, satisfying ways to express your emotions.
And
if such a prescription seems too challenging, seek professional help to feel
better. I believe the alternative or complementary therapies are a form of
professional help much less likely to do harm and more likely to do good than
conventional approaches. They work by shifting our natural balance of internal
chemicals around, so we can feel as good as possible. They are often
particularly helpful for alleviation of the many chronic maladies that
currently have no good medical solutions (see Appendix B).
Consciously and
lovingly acknowledge each family member before sleep. That is, say goodnight.
Don’t program your bodymind with images of death, destruction, and the bizarre
before retiring. Translation: Never wind down with the nightly news. Instead,
try a book, a relaxing hobby, a hot bath, or even light housework.
Last, but
definitely not least, health is much more than the absence of illness. Live in
an unselfish way that promotes a feeling of belonging, loving kindness, and forgiveness. Living like this promotes a state of spiritual bliss
that truly helps to prevent
illness. Wellness is trusting in the ability and desire of your bodymind to
heal and improve itself given half a chance. Take responsibility for your own
health—and illness. Delete phrases like, “My doctor won’t let me …” or, “My doctor says I have [name of
condition], and there is really nothing I can do” from your speech and thought
patterns. Avoid unscientific beliefs about your need for medications and
operations.
APPENDIX B
BODYMIND MEDICINE: RESOURCES AND PRACTITIONERS
Although I am
a scientist and not a clinician, I am of the strong opinion that complementary
therapies can not only help with chronic degenerative diseases like cancer,
arthritis, heart disease,
and autoimmune disorders, but also with other health problems, such as
asthma, premenstrual syndrome, headaches, sinusitis, and gastrointestinal disorders, for which conventional medicine can offer
only incomplete or no help. Complementary therapies can also enrich our lives
so we can live them more fully and joyfully. Following is a list of resources
related to bodymind medicine to help you find further
information about therapies or
locate a practitioner in your area.
For this
section, I am most fortunate—and very grateful—to have had the collaboration of Jacqueline C. Wootton, M.Ed., my friend and neighbor
as well as colleague, and a
long-standing expert in alternative medicine information resources. The therapies, treatments, and approaches represented by the following
organizations are those I think are most relevant for impacting on the
molecules of emotion, some of which I’ve touched on in the book. The
compilation is a selection from Jackie’s database of resource
organizations, which is freely
available on her World Wide Web site (http://www.clark.net/pub/Alt
MedInfo/); the information was correct as of January 15, 1997, and is kept
updated at this site. To obtain additional materials, see the details at the
end of this section.
Jackie has
organized the list according to categories relevant to the theme of the book.
She would point out that this categorization is neither definitive nor
complete; several therapies could be grouped differently. Specific
biological/pharmacological treatments have not been included, nor have
homeopathy and herbal medicine, except where they are part of a complete system
of traditional medicine. Some sections, such as cancer care and meditation,
have been expanded to include treatment centers or training facilities.
We offer you this
information in the spirit of promoting personal responsibility for health.
Inclusion in this list does not constitute our
endorsement.
You will find that some of these organizations give conflicting
recommendations, so you would be wise to research a range of different viewpoints and recommendations in order to
reach your own health and wellness decisions.
Please note,
also, that the following information was as accurate as we could make it at the
time we went to press. Unfortunately, addresses, phone numbers, and other
aspects of this listing are constantly subject to change, so please be
understanding in using this material for reference.
