Virginia M.-Y. Lee, Ph.D.
Professor of Pathology and Laboratory Medicine
Co-Director of the Center for Neurodegenerative Disease Research at UPENN's School of Medicine
First recipient of the John H. Ware 3rd Chair for Alzheimer's Disease Research.
Virginia Lee’s research interest focuses on tau, α-synuclein, TDP-43 and amyloid β precursor protein (APP), and their roles in the pathobiology of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), frontotemporal dementias (FTD) and amyotrophic lateral sclerosis (ALS). In particular, her lab wants to determine the pathogenesis of senile plaques, Lewy bodies, neurofibrillary tangles and TDP-43 aggregates because these are major lesions found in the brains of AD patients and other neurodegenerative diseases. Information obtained from this research may shed light on how neurons degenerate in AD and PD and lead to a better understanding of the etiology of these diseases. A multi-disciplinary approach (including biochemical and molecular studies of neuronal culture systems, animal models and human tissues obtained at autopsy) is used in the laboratory to address research issues in common with these neurodegenerative diseases. Other research efforts focus on an increased understanding of the normal functions of tau, synuclein, APP and TDP-43. Finally, her lab is involved in research to advance drug discovery in Alzheimer's disease and Parkinson's disease.
