The Brain Research Institute welcomes six new members Dr. Christopher Giza,Assistant Professor of Surgery, Division of Neurosurgery, and Assistant Professor of Pediatrics, Division of Neurology; Dr. Charles Glatt, Assistant Professor of Psychiatry and Biobehavioral Sciences; Dr. Ming Guo, Assistant Professor of Neurology; Dr.Russell Poldrack, Assistant Professor of Psychology; Dr. Daniel Silverman, Assistant Professor of Molecular and Medical Pharmacology, and Head, Neuronuclear Imaging Research Group; and Dr. Xiangdong William Yang, Assistant Professor of Psychiatry and Biobehavioral Sciences, recently joined the Brain Research Institute.
Christopher Giza received an M.D. degree from West Virginia University School of Medicine in 1990. He completed his internship in the Department of Medicine at the Hospital of the University of Pennsylvania in 1991. Moving to UCLA, Dr. Giza then completed a residency in neurology, and a clinical fellowship in the Division of Pediatric Neurology, Department of Pediatrics at the UCLA Mattel Children’s Hospital. From 1996-1997, Dr. Giza was a Search and Rescue Team Member in Yosemite National Park. Returning to UCLA in 1997, Dr. Giza has served in several capacities including staff research assistant in the NPI and Division of Pediatric Neurology, and postdoctoral fellow and assistant researcher in the Division of Neurosurgery, Department of Surgery. Dr Giza is currently an assistant professor in the Division of Neurosurgery and the Division of Pediatric Neurology.
Dr. Giza’s research interests focus on traumatic brain injury, neural development, and plasticity. Describing his research projects, Dr. Giza states, “Traumatic brain injury (TBI) is the number one cause of death and disability in the pediatric age group. Using anatomical, physiological, behavioral and molecular techniques, we are seeking to better understand the effects of biomechanical injury to the immature brain. Following developmental TBI, there is evidence of impaired environmental responsiveness in the absence of significant cell death. This indicates that neurons may be in a state of dysfunction that renders them less able to manifest normal neural plasticity. Our first studies have been aimed at characterizing this loss of plasticity by measuring anatomical, molecular and behavioral responses to rearing in an enriched environment following experimental TBI. The second project is investigating the role of glutamate receptor changes in this plasticity impairment after developmental TBI. Molecular changes in the amount and composition of glutamate receptors can have important functional consequences with regards to ionic flux, synaptogenesis and electrophysiology. Lastly, post-TBI neural dysfunction may manifest by altered vulnerability to a second injury. Using physiological stimuli such as seizure activity, or specific pharmacological toxins, we are studying mechanisms that result in enhanced sensitivity of traumatically-injured neurons to secondary insults.”
Charles Glatt received an M.D., Ph.D. degree in neuroscience from Johns Hopkins University School of Medicine in 1994. He completed a residency in psychiatry at the Langley Porter Psychiatric Institute, followed by a postdoctoral fellowship, at UC San Francisco. Moving to Los Angeles, Dr. Glatt joined UCLA and is currently an assistant professor in the Department of Psychiatry and Biobehavioral Science.
Dr. Glatt’s research interest is behavioral genetics. He states, “My current research focuses on developing novel approaches to complex genetic traits with a particular focus on behavioral genetics. This process involves identifying genetic variation in genes related to monoamine neurotransmission and identifying genotype-phenotype correlation at the molecular level. This information will allow novel analyses of association studies that will increase statistical power by grouping multiple interacting variants. These novel approaches will then be applied to several association studies including antidepressant response and Parkinson’s disease.
Ming Guo received an M.D. degree from Shanghia Medical University School of Medicine in 1989, and a Ph.D. degree from the University of California, San Francisco in 1996. Dr. Guo’s Ph.D. thesis research was conducted in the laboratory of Dr. Yuh Nung Han in the Howard Hughes Medical Institute at UCSF, and concerned the “Control of neuronal fate during asymmetric divisions: interaction of numb, Notch and tramtrack.” Dr. Guo completed a postdoctoral fellowship at UCSF in 1997, and a residency in neurology at UCLA in 2001. Working in the laboratory of Dr. Larry Zipursky, Dr. Guo conducted research as a postdoctoral fellow identifying regulators for g-secretase activity implicated in Alzheimer’s disease in Drosophila. During this time, she was also clinical instructor in neurodegenerative disorders. Dr. Guo is currently an assistant professor in the Department of Neurology.
Describing her research, Dr. Guo states, “We are interested in understanding the pathogenesis of Alzheimer's disease (AD). One of the pathological hallmarks of AD is the accumulation of amyloid plaques consisting of a toxic peptide called A-beta. A-beta is generated from a transmembrane protein, amyloid precursor protein (APP), through the action of two proteases, one of which is gamma secretase.
Gamma secretase is contained in a large multi-protein complex, of which Presenilin and Nicastrin are two components. Since regulators of g-secretase activity are likely to be disease modifiers and therapeutic targets, the identification of other components in the gamma secretase complex and proteins that regulate gamma secretase are critical and set the goals of our research. We aim to identify regulators of g-secretase through function-based in vivo genetic screens in Drosophila, and then to translate these findings into human studies. Using Drosophila will allow us to perform large-scale screens encompassing the majority of the Drosophila genome in a relatively short period of time. We have created flies that act as living reporters for the levels of endogenous g-secretase in the Drosophila eye, a neuronal tissue not essential for fly viability or fertility. The biological readout in this reporter system is eye size. Flies with high levels of g-secretase activity have small eyes, while those with low levels have large eyes. We have shown that the reporter eye phenotype is dependent on the normal function of Presenilin and Nicastrin. Using these flies as backgrounds, we have carried out genetic screens for enhancers and suppressors of g-secretase activity.
Two screens that we completed have yielded a number of candidate genes for encoding regulators of g-secretase activity. Currently we are in the process of cloning some of the candidates and characterizing their products. We will focus on genes that have human homologs. Our immediate goal is to determine the mechanism of action of these genes. An important long-term goal is to determine if these genes or their products have diagnostic value to identify human AD susceptibility or resistance genes and/or have potential as drug targets.”
Russell Poldrack received a Ph.D. in cognitive psychology from the University of Illinois, Urbana, in 1995. His doctoral thesis focused on the “Relationship between skill leaning and repetition priming.” Upon completion of his degree, Dr. Poldrack was a postdoctoral fellow in the Department of Psychology at Stanford University. Since 1999, Dr. Poldrack has served as Assistant Psychologist at the Massachusetts General Hospital, and Assistant Professor of Radiology at Harvard Medical School. He is currently a member of the Faculty of the Harvard Graduate School of Education, while concurrently Assistant Professor of Psychology at UCLA.
Describing his research interests, Dr. Poldrack states, “The research in our lab uses functional magnetic resonance imaging to investigate the nature of learning-related changes in human brain function. One major focus is on understanding the mechanisms that support learning of new skills. Current projects are investigating the neural basis of classification learning, and the role of cholinergic mechanisms in the modulation of perceptual learning. Another major focus of the lab is on the neural basis of reading and reading disorders. Ongoing projects are investigating the changes in neural processing associated with the development of reading skill, and the neural correlates of intervention for dyslexia. A third focus of the lab is on the executive control processes mediated by the prefrontal cortex, particularly in the context of language processing.”
Daniel Silverman, received his Ph.D. degree in biological chemistry from Harvard University in 1987, and an M.D. degree from Ohio State University in 1992. He completed a postdoctoral fellowship in biochemistry and molecular pharmacology at Harvard Medical School in 1988, and upon completion of his medical degree, moved to Los Angeles where he completed a residency in internal medicine at UCLA, and a fellowship in nuclear medicine. Dr. Silverman is currently an Assistant Professor of Molecular and Medical Pharmacology, and Head of the Neuronuclear Imaging Research Group.
Describing his research, Dr. Silverman states, “The two major goals of our research program are to explore in living human brain the interactions and neurologic bases of memory, mood, and pain perception, with respect to both normal and disordered function (as occurs in dementia, depression and chronic pain syndromes), and to
Xiangdong William Yang, received a Ph.D. degree from the Rockefeller University in 1998, and then completed a postdoctoral fellowship in the Laboratory of Molecular Biology at the Rockefeller University with Dr. Nathaniel Heintz. There he developed a high throughput method to modify bacterial artificial chromosomes (BACs) and to isolate relatively full length cDNAs from BACs. Dr. Yang then completed an M.D. degree at The Joan and Sanford I. Weill Medical College of Cornell University in New York in 2000. During the years 1999-2002, Dr. Yang completed an internship in the Department of Medicine at New York Presbyterian Hospital/Weill Cornell Medical Center, and was a co-principal investigator in the Hereditary Disease Foundation Cure Huntington’s Initiative, and a participant in the Venezuela Collaborative Huntington’s Disease Project under the direction of Dr. Nancy Wexler. Dr. Yang joined UCLA in 2002 as Assistant Professor in Department of Psychiatry and Biobehavioral Sciences and the Neuropsychiatric Institute.
Describing his research interests in neurodegenerative disease, Dr. Yang states, “My laboratory is interested in using the mouse genetic approach to study the pathogenesis and to identify potential therapeutic strategies for neurodegenerative diseases, particularly for Huntington’s disease (HD) and Parkinson’s Disease (PD). In addition to

UCLA RECEIVES TWO NIH CENTER GRANTS
NIEHS Announces $20 Million, Three-Center Effort to Pin-Point Environmental Triggers of Parkinson's
The National Institute of Environmental Health Sciences, a component of the National Institutes of Health, announced five-year grants totaling $20 million for three centers to conduct research on the relationship between exposures to environmental agents and subsequent Parkinson's disease. The three centers will be located at the Parkinson's Institute, in Sunnyvale, California, Emory University, Atlanta, Georgia., and theUniversity of California at Los Angeles.
NIEHS Director Kenneth Olden, Ph.D., said in announcing the new funding, “Our best chance for finding successful treatments for persons suffering with Parkinson's disease is to understand more about what triggers the disease. Even better, this research may lead to ways to prevent Parkinson's disease in the first place.”
A progressive disorder characterized by muscular rigidity and tremors, slow movement and impaired balance and coordination, Parkinson's disease affects between 1 and 1.5 million people in the U.S., with 50,000 newly diagnosed cases a year.
Recent findings suggest that Parkinson's may result from a combination of a person's exposure to harmful environmental agents and the person's inherited susceptibility. The disease is marked by the death of cells in the brain that produce and release the neurotransmitter dopamine. Current drug therapies, which attempt to replace the lost dopamine, can relieve some symptoms but do not cure or slow the disease.
The center located at: The Parkinson's Institute, Sunnyvale, California, will be directed by J. William Langston, M.D. This center will examine risks associated with pesticides and heavy metals, possible protective effects of tobacco and caffeine, the underlying mechanisms of dopamine cell death, and genetically determined susceptibility traits for Parkinson's disease.
The center at Emory University, Atlanta, Georgia, directed by J. Timothy Greenamyre, M.D., Ph.D., will develop new cellular and animal models to study gene-environment interactions in the development of Parkinson's disease and will focus on how pesticides interact with the proteins that package dopamine within nerves, and the cellular machinery that degrades abnormal proteins.
The center at UCLA directed by Marie-Françoise Chesselet, M.D., Ph.D., will study how variations in genes that regulate dopamine levels within neurons may play a role in the increased risk of Parkinson's disease associated with pesticides, using several model systems as well as human cells and DNA samples from two large and unique California studies of Parkinson's disease.
Dr. Olden said that the three centers will conduct their research independently but will also have the benefit of acting as a consortium, collaborating and taking advantage of each other's knowledge and expertise. He said, “We have some good clues about what environmental agents and genes may be important in Parkinson's disease. This new consortium should bring together the right mix of scientists so that these leads can be pursued quickly.”
J. William Langston, MD., founder and CEO of the Parkinson's Institute, said, “This could be the final chapter of our search for the cause of Parkinson's disease. Under the auspices and funding of NIEHS, three major research institutes will collaborate to find the environmental and genetic origins of Parkinson's. Working together we can accelerate the pace of research with a dream team of multi-disciplinary experts."
Joan Samuelson, founder of the Parkinson's Action Network, said, “The environmental link provides major clues in unraveling Parkinson's remaining mysteries. The cure will be accelerated by this tremendous commitment of funding and focused effort. That translates into less suffering for the million Americans with Parkinson's. We are filled with hope and gratitude by this endeavor.”
Deborah W. Brooks, executive director of the Michael J. Fox Foundation for Parkinson's Research, said, “The NIEHS and Director Olden have designed a creative approach to targeting this exciting area of Parkinson's research. Structuring collaboration among these three strong multidisciplinary teams should surely accelerate progress in what we continue to believe is a winnable war against Parkinson's Disease.”
Congratulations to Marie Francoise Chesselet and the terrific team she has assembled--Jeff Bronstein, Nelson Freimer, Charles Glatt, David Krantz, Mike Levine, Nigel Maidment, Beate Ritz, Erik Schweitzer, and others...--for their newly funded cooperative effort to find environmental triggers of Parkinson's disease. This new center again illustrates how crossing disciplinary and departmental boundaries can accelerate the translation of basic-science information into disease-related discovery.
UCLA Receives NIH Grant to Create First National Center for Neurovisceral Sciences and Women's Health
The National Institutes of Health awarded UCLA $3.75 million to create a new national research center to be named the Center for Neurovisceral Sciences and Women's Health (C.N.S). The new center --the first of its kind--will study how the brain, stress and emotions impact the development of disorders that affect mainly women-including such common diseases as irritable bowel syndrome (IBS) and interstitial cystitis (IC). The new center will develop research programs as well as a comprehensive clinical center that will see patients. The Center will study the role of brain, stress and emotions in IBS, IC and related disorders.

Dr. Herbert Weiner, whose pioneering research into mind-body connections contributed to the rise of psychosomatic medicine as a distinct field, died of lung cancer Tuesday, November 12, 2002, at his Encino home. He was 81.
A psychiatrist who taught for two decades at UCLA, Weiner had an international reputation as a leading researcher in the field.
He was the author of two books, "Psychobiology and Human Disease" (1977) and "Perturbing the Organism: The Biology of Stressful Experience" (1992), and he co-wrote or edited 20 others. He also was the editor of a leading journal, Psychosomatic Medicine, for a decade ending in 1982.
"He brought a level of scientific inquiry to the field," said Dr. Michael Irwin, a professor at UCLA's Neuropsychiatric Institute. "He asked, 'How do we set up experiments to evaluate how the brain communicates with the body and how stress impacts health?' That was his stamp."
In the 1950s, Weiner investigated how psychological processes and behavior affected the development of gastric ulcers and other diseases and found that stress was a contributing factor.
He later conducted research on the effects of behavior on other illnesses, including peptic ulcers, bronchial asthma and rheumatoid arthritis.
In the 1970s, Weiner was one of the first researchers to report on the behavioral effects of hydrocortisone, a drug commonly used to treat auto-immune disorders such as asthma. He also was involved in studies that contributed to the development of psychoneuroimmunology, which examines the influence of the brain on the immune system. Among the seminal studies he participated in was one showing how grieving over spouses who died of lung cancer impaired the immune systems of women.
Weiner was also known as an exceptional teacher who trained more than 120 physicians and researchers. According to Irwin, many of his students have won prestigious awards and headed the psychiatry departments of leading universities.
Born in Vienna in 1921 and raised in London, Weiner came to the United States with his family in 1939. He graduated from Harvard College in 1943 and earned his medical degree from Columbia University in 1946.
During the 1950s and '60s he was a researcher at Walter Reed Army Hospital in Bethesda, Maryland., and at Albert Einstein College of Medicine in New York. From 1969 to 1982, he headed the psychiatry department at Montefiore Hospital and Medical Center in Bronx, N.Y.
In 1982, he became the chief of behavioral medicine at UCLA and worked at the university's Neuropsychiatric Institute and Brain Research Institute. He retired last year.
He is survived by his wife of 49 years, Dora, a professor of medical humanities and history at UCLA; three sons, Tim of Mexico City, Richard of Brussels and Tony of Arlington, Mass.; seven grandchildren; and a sister, Mary Black, of Beaufort, S.C.
Dr. Wiener will be missed both personally and professionally. He was an outstanding researcher, and an active member of the Brain Research Institute for many years, heading up major BRI training grants in psychoneuroimmunology.
In lieu of flowers, the family asks that contributions be sent to The Herbert Weiner Early Career Award, which supports promising young researchers, c/o the American Psychosomatic Society, 6728 Old McLean Village Drive, McLean, VA 22101-3906. Kindly included “Weiner Award” in an accompanying note.
