Detailed Biography:

T cells utilize the T cell receptor (TCR) to specifically recognize antigen in association with self MHC and to signal one of several distinct responses. Under different circumstances, a T cell responds to TCR stimulation by proliferating, differentiating along a particular developmental pathway, producing lymphokines, releasing cytotoxic granules, dying or by becoming anergic. It remains unclear how the functional outcome of TCR engagement is determined . Recent data indicate that the organization of surface receptors, membrane microdomains and signal transducers at the T cell synapse provides a cellular context for TCR/costimulator signal transduction and effector molecule delivery. Lipid raft membrane compartmentalization, intracellular molecular scaffolding, and lectin induced surface glyco-lattice formation represent three potential mechanisms for organizing synaptic microdomains and influencing the outcome of antigenic stimulation. Ongoing studies are aimed at elucidating how alternate microdomain organization can influence contextual TCR signal transduction and how T cell subpopulations differentially capitalize on microdomain organization schemes to modify TCR/costimulator signal transduction and mediate effector function. Further elucidation of modulators of TCR signals and functions may allow for the intelligent design of vaccines or therapies aimed at immune activation or tolerance induction. Our work directly relates to basic mechanisms of immune regulation, signal transduction, tolerence induction, autoimmunity, and oncogenesis.
