Jeffrey L. Platt , M.D.
Professor of Surgery
Professor of
Microbiology and Immunology


Research interests:
Transplantation immunology, immunological recognition, immunologic and genomic stability of stem cells, activation and control of TLR

Current Research Activity:

Dr. Platt's research focuses on the biology of transplantation and related fields. The research poses such questions as how does the immune system become activated by foreign cells and how does the activated immune system destroy a graft. An important line of this research concerns the mechanisms through which a graft, or any tissue, acquires resistance to immune-mediated injury, a phenomenon Dr. Platt originally described and named “accommodation.” Dr. Platt investigates diverse repertoires of B cells and T cells develop, how they are maintained, and how that system can be reconstituted for treatment of immunodeficiency, chronic viral infection, or cancer. Also investigated are endogenous mechanisms of activation and control of toll like receptor function in health and disease and the mechanisms and implications of cell and nuclear fusion.
