Current Research and Scholarly Interests

Over the years my laboratory addressed scientific problems related to neuroscience, genetics, psychiatry, neurology and addiction medicine. Initially, we investigated expression of beta amyloid and related markers in Alzheimer’s disease brain. Simultaneously we developed cell culture models using astrocytes and microglia to investigate production of cytokines by glia, thus defining the inflammatory repertoire of these cells. Next, we began human genetics studies to assess the effect of the APOE epsilon 4 allele on clinical phenotypes in Alzheimer’s disease and other conditions. We then employed organotypic hippocampal explant cultures to study glial-neuronal interactions. This involved utilizing confocal microscopy to image cells in the 3-dimentional hippocampal cultures, as well as implementing PCR techniques for quantifying gene expression in minute volumes of tissue. Ultimately, we developed a microglia-hippocampal co-culture model with genetically engineered exogenous microglia to study cell-cell inflammatory processes. With this model we discovered novel effects of inflammatory cytokines on neurons. We also engineered endogenous microglia in the organotypic cultures using biolistics, to confirm results obtained in the co-cultures. We were early adopters of microarray technology for studying gene expression as well as for genotyping and DNA sequencing. We applied microarray approaches to gene expression in transgenic mouse models for Alzheimer’s disease, identifying a variety of markers induced by brain amyloid beta. Simultaneously, we were among the first to apply microarray technology to genotyping for markers for clinical medication response, adverse reactions, and metabolism. Finally, we performed large scale genotyping studies to identify markers for antidepressant response and response to medications for smoking cessation.

Clinical Trials

Genetics of Symptomatology and Treatment Response in Psychotic Major Depression Not Recruiting
More
We hope to learn more about the biology of psychiatric illness with the hope of improving the diagnosis and treatment of such psychiatric conditions as major depression.

Stanford is currently not accepting patients for this trial. For more information, please contact Gregory H Cohen, MSW, 650-723-3305.

Stephen P. Fortmann, MD

C.F. Rehnborg Professor in Disease Prevention, Emeritus
Research Interests
Dr. Fortmann's interests include population-level (community) prevention of cardiovascular disease, the epidemiology and prevention of chronic diseases, and the effects of the built environment on health.

Rona Giffard

Professor of Anesthesiology, Perioperative and Pain Medicine, Emerita
Research Interests
Astrocytes, microglia and neurons interact, and have unique vulnerabilities to injury based on their patterns of gene expression and their functional roles. We focus on the cellular and molecular basis of brain cell injury in stroke. We study the effects of altering miRNA expression, altering levels of heat shock and cell death regulatory proteins. Our goal is to improve outcome by improving mitochondrial function and brain cell survival, and reducing oxidative stress and inflammation.

Helena Chmura Kraemer

Professor of Biostatistics in Psychiatry, Emerita
Research Interests
I am interested in the methodology pertinent to dealing with research problems where biological and behavioral interests meet. These interests have been applied not only in psychiatric research, but in those areas of Cardiology, Pediatrics and other fields of medicine in which behavioral research is becoming ever more salient.

Ruth O'Hara

Director, Spectrum, Senior Associate Dean, Research and Lowell W. and Josephine Q. Berry Professor
Research Interests
Dr. O'Hara's research aims to investigate how cognitive information processing deficits subserve affective symptoms in psychiatric disorders, and interact with key brain networks integral to these disorders. To do so, she has implemented a translational, interdisciplinary program that encompasses cellular models, brain and behavioral assays of affective and cognitive information processing systems in psychiatric disorders across the lifespan.
