Symposium
to Explore Drug Abuse and Addiction
Why does the use of heroin, cocaine and alcohol lead to life-threatening
dependency in some people, while others never become addicted? And
why do some people succeed in treatment, while others continue to
relapse?
Centennial Lecture

Alan
Leshner, Director, National Institute on Drug Abuse, will
present a Centennial lecture on drug abuse.

On Thurs., March 29, Alan Leshner, director of the National Institute
on Drug Abuse, will present a special Centennial Lecture on Science
and Society entitled "Bringing the Power of Science to Bear
on Drug Abuse and Addiction." Exploring how genetic research
and new brain-scanning technologies are shedding light on risk factors,
Leshner also will discuss the changes that result from short- and
long-term drug abuse, and describe how this new understanding will
have an impact on the future of treatment and prevention.
Symposium
On Fri., March 30, six leaders in the field of addiction re-search
will present an overview of the latest scientific findings on cocaine,
opiate and alcohol addiction in a symposium entitled "The Biology
of Drug Abuse and Addiction: More Tangled Than Traffic."

speaker Mary Jeanne Kreek is a professor and head of the Laboratory
of the Biology of Addictive Disease at The Rockefeller University;
she also is senior physician of The Rockefeller University
Hospital.

The modern field of addiction research was launched at The Rockefeller
University Hospital in the 1960s, when then-Professor Vincent Dole
began testing methadone as a treatment for heroin dependency. Today,
many of Doles ideas serve as the foundation for research on
drug addiction in laboratories around the world. At Rockefeller,
cutting-edge research on addiction continues under the leadership
of one of Doles former colleagues, Mary Jeanne Kreek, who
heads the Laboratory of the Biology of Addictive Diseases and directs
a major interdisciplinary center at Rockefeller funded by the National
Institute on Drug Abuse.
In addition to Kreek, speakers at the symposium include Enoch Gordis,
director of the National Institute on Alcohol Abuse and Alcoholism,
NIH; Nora Volkow, associate director for life sciences, Brookhaven
National Laboratory; Charles OBrien, chief of psychiatry,
Veterans Affairs Medical Center, University of Pennsylvania; Eric
J. Nestler, Lou and Ellen McGinley Distinguished Professor and chairman
of the Department of Psychiatry at The University of Texas Southwestern
Medical Center, Dallas; and Chris Evans, a professor at the University
of California, Los Angeles.
Gordiss principal goals as a physician and director of the
National Institute on Alcohol Abuse and Alcoholism (NIAAA) are to
establish the Institute and alcohol research as leaders in science
and medicine and to facilitate the use of alcohol research findings
to improve prevention and treatment. Prior to becoming director
of the NIAAA in 1986, Gordis spent 10 years at The Rockefeller University
in the Dole laboratory, founded and directed one of New York Citys
largest and most comprehensive alcoholism treatment programs at
Elmurst Hospital and served as professor clinical medicine at Mt.
Sinai School of Medicine.
Nora Volkow uses positron emission tomography (PET) to investigate
the biochemical changes in the brain associated with drug addiction,
alcoholism and aging. Her studies include research on Ritalin and
cocaine, which are chemically similar, and their pathways and functioning
in the brain. Volkow is focused on finding an effective pharmacological
treatment of addiction, and her research could also aid in finding
avenues for delaying and counteracting the deleterious effects of
aging.
Charles OBriens research group has been responsible
for documenting the relationship between opioid agonists and alcohol
addiction. Drugs such as naltrexone have been developed and approved
as treatment as a result of this work. OBriens interest
in the pharmacology of addiction is always coupled with the development
of new behavioral therapies that constitute a full psychopharmacological
approach.
Eric J. Nestler studies the molecular adaptations induced in the
brain after chronic administration of opiates, cocaine and other
drugs. One of his goals is to more completely identify and characterize
such adaptations and to relate specific adaptations to drug-induced
alterations in neuronal function that define an addicted state.
Nestler utilizes methods of viral-mediated gene transfer and genetic
mutations in mice to establish causal relationships among molecular,
cellular and behavioral levels of analysis.
Chris Evans led one of two teams that concurrently cloned the delta
opioid receptor by functional expression in 1992. This accomplishment
enabled the molecular characterization of the family of opioid receptors
and helped to elucidate the mechanisms by which drugs interact with
the opioid receptors in the brain. In ongoing research Evans uses
immunochemical techniques in cell lines and in rats to further characterize
the properties of the opioid receptor family with the goal of refining
treatments and minimizing side effects associated with the opioid
class of drugs.
