Research Interests

Our lab is primarily interested in molecular factors that control the decision between tolerance and immunity within T lymphocytes. We use staphylococcal enterotoxins, recombinant vaccinia viruses, lymphocytic choriomeningitis virus and MHC tetrameric reagents as tools to study antigen -specific T cell responses. Our interest in tolerance centers on regulation of mechanisms that control the survival and death of activated T cells in vivo, namely Bcl-2 and its antagonist Bim. We are also interested in the manipulation and regulation of antigen-specific T cell responses via novel vaccine strategies to either induce tolerance or enhance immunity. Finally, we are interested in mechanisms underlying sex-based differences in T cell responses and how these differences relate to autoimmune disease.
