Current Research

My current research interest focuses on the role of immune cells and inflammation in a variety of disease states including cancer, Alzheimer’s disease, and Parkinson’s disease. In our model of melanoma, we show that a critical concentration of CD8+ cytolytic killer T- cells is required to eradicate the tumor. In addition, only a small percent of the CD8+ T- cells are actually cytolytic. We are now examining methods to increase the percentage of cytolytic T- cells in order to dramatically improve the eradication of this tumor. In Alzheimer’s disease we have identified the pivotal role of scavenger receptors in microglial cell processing of extracellular beta amyloid. Extracellular beta amyloid fibril accumulation is thought to trigger an inflammatory response that promotes neurodegeneration in Alzheimer’s disease. We are examining methods to reduce neuroinflammation in this disease. In Parkinson’s disease (PD), extracellular accumulation of alpha synuclein and nitrated alpha synuclein are thought to trigger neurodegeneration. We have identified beta 2 integrins and CD36 scavenger receptors in the interaction of microglial cells with matrix-bound synucleins and are examining how these receptors function in clearing extracellular synucleins. In addition, we show data that neurodegeneration in PD is also mediated by a CD8+ T cells that specifically target the dopaminergic neurons destroyed in the substantia nigra in these patients. Our goal here is to develop protocols to attenuate or stop T- cell mediated neurodegeneration in PD. In addition to my research and teaching in immunology, I teach and publish on current dilemmas in bioethics.
