With sadness I share that Terrell Gibbs, PhD, associate professor of Pharmacology & Experimental Therapeutics, died Friday, August 15, at M.D. Anderson Cancer Center in his home state of Texas. A member of the BUSM faculty for 24 years, Dr. Gibbs received his undergraduate degree in biology from MIT and his doctoral training in pharmacology from Harvard Medical School. He pursued his interests in neuropharmacology, first at Downstate Medical Center in the Department of Anatomy & Cell Biology at SUNY Health Science Center in Brooklyn, NY, and then at Boston University working in close collaboration with Pharmacology Chair Dr. David Farb.
Dr. Gibbs’ research involved elucidation of the molecular mechanisms of modulation of GABAergic function by benzodiazepines and neurosteroids and of CNS abnormalities such as autism. His discoveries were revealed in more than 45 publications and many abstracts presented at the Society of Neuroscience Annual Meetings.
A recent recipient of the Excellence in Education and Mentoring Award from the Neurosteroid Congress, he played a key role in the design and implementation of the curriculum for the Biomolecular Pharmacology Predoctoral Training Program at Boston University and guided innumerable PhD candidates. He taught medical, dental, and master’s degree students at BU the principles of pharmacology and the actions of drugs affecting the peripheral and central nervous system. All medical students over the past 23 years have learned the principles of pharmacodynamics under his tutelage.
His interest in pharmacologic research in many areas and rational evaluation of evidence of drug efficacy and safety were hallmarks of his approach as an educator and served as an outstanding role model for both students and faculty.
Dr. Gibbs also was renowned for his expertise in the martial arts, which he occasionally practiced on the Talbot Green.
He will be greatly missed by his students and his faculty and staff colleagues.
He is survived by his step-mother, brother and sister, half-sister and half-brother, and nieces and nephews.

Researchers at Boston University School of Medicine (BUSM) have uncovered important clues about a biochemical pathway in the brain that may one day expand treatment options for cognitive deficits seen in schizophrenia. The study, published online in the journal Molecular Pharmacology, was led by faculty members David H. Farb, PhD, Terrell T. Gibbs, PhD, and Shelley J. Russek, PhD in thedepartment of pharmacology & experimental therapeutics at BUSM.
Patients with schizophrenia suffer from a life-long condition that can produce cognitive deficits, delusions, disordered thinking, and breaks with reality. A number of treatments are available for the treatment of schizophrenia, but many patients do not respond to these therapies or experience side effects that limit their use. There is no current treatment for the cognitive deficits experienced in schizophrenia.
The healthy brain is made up of billions of cells including the primary signaling cells called neurons, that are responsible for managing everything the body does: including movement, eating behavior, and memory formation. These neurons acts like a miniature computer and are controlled by substances called neurotransmitters that, like bits in a computer chip, may be “turned on” or “turned off” depending on the specific signals being integrated. Neurotransmitters latch onto a cell via a specific receptor, like a key fits into a lock.
In schizophrenia, it is thought that certain neurons don’t “turn on” as well when exposed to a certain neurotransmitter, the amino acid glutamate, may not be sensed by one of its key receptors (the NMDA receptor) whose diminished function may be the possible culprit for these sluggish cells. It is thought that this deficit can at least partially be responsible for symptoms seen in schizophrenics.
Currently the therapeutic means for making these cells more “sensitive” to glutamate can be toxic to the brain.
In this study, researchers discovered that another, naturally occurring steroid within the brain, known as PregS, may be able to bypass this toxic effect, and “turn on” neuron communication safely through a novel mechanism. The implication is that a deficit in the amount of this novel steroid may underlie deficits in signaling and that stimulation using therapeutics that elevate its levels in the brain may decrease or eradicate some of the debilitating symptoms seen in schizophrenia.
Although still in the early stages, further research in this area may be instrumental in the identification and development of treatments not only for schizophrenia, but also for other neurological conditions, such as age-related decreases in memory and learning ability.

Shelley J. Russek, PhD, professor of pharmacology at Boston University School of Medicine (BUSM), and director of the School’s Graduate Program for Neuroscience, was recently honored with an award from the CURE (Citizens United for Research in Epilepsy) Foundation. The prestigious award, given as well to her colleague Amy Brooks-Kayal, MD, from University of Colorado Denver, will fund research studies for new drugs for epilepsy treatment.
Approximately 65 million people worldwide have epilepsy. Although certain brain injuries are known to predispose someone to epilepsy, there are no treatments that reduce this risk. Russek and her colleagues have found that an important cellular signaling pathway, the JAK/STAT pathway, is activated after brain injuries that lead to epilepsy, and that inhibiting this activation reduces subsequent seizure frequency in an experimental model. “We expect to identify lead JAK/STAT inhibitors that can be advanced towards clinical testing to prevent or inhibit development of acquired epilepsy following brain injury,” explained Russek.
CURE was founded by parents of children with epilepsy who were frustrated with their inability to protect their children from the devastation of seizures and the side effects of medications. Unwilling to sit back and accept the debilitating effects of epilepsy, these parents joined forces to spearhead the search for a cure. Each year, grants are funded based on promising trends in the field and the potential for breakthroughs in a specified area. Russek was selected with the assistance of the CURE Scientific Advisory Board, the Lay Review Council, and the scientific peer reviewers who generously volunteer their time to CURE.
CURE has raised more than $26 million to fund research and other initiatives. CURE funds seed grants to young and established investigators to explore new areas and collect the data necessary to apply for further funding by the National Institutes of Health. To date, CURE has awarded 151 cutting-edge projects.

The Peter F. McManus Charitable Trust Foundation recently honored Dr. Valentina Sabino for the second time with a grant to research the causes of alcohol addiction. The title of her approved project is “Neurobiological Bases of Alcohol Addiction.”
According to Dr. Sabino, “alcoholism constitutes one of the most serious public health problems worldwide. The World Health Organization estimates that about 2 billion people worldwide consume alcoholic beverages, of which 76.3 million have alcohol use disorders. Alcohol is estimated to cause 20%–30% of esophageal cancer, liver cancer and cirrhosis, homicide, seizures, and motor vehicle accidents, causing 3.2% of the total deaths.
This project will systematically explore the role of an understudied receptor system, the Sigma receptors, in genetic and chronic ethanol-induced animal models of alcoholism. The focus will be the Nucleus Accumbens, an important brain region for alcohol and drug addiction, proposed as being the specific region where Sigma receptors mediated neuroplasticity in addicted brains.
These experiments will provide insights into this novel receptor system as a key mechanism involved in excessive drinking and alcohol-seeking behavior and propose a novel therapeutic target for alcohol addiction.”
Dr. Sabino received her Ph.D. in Pharmacology in 2006. She is an Assistant Professor in the Department of Pharmacology & Experimental Therapeutics and Department of Psychiatry, and Co-Director of the Laboratory of Addictive Disorders at Boston University School of Medicine.
Congratulations, Dr. Sabino!
