Research Interests

T-Lymphocyte activation; cell-cell interaction and transmembrane signaling. Work in our laboratory focuses on understanding the requirements for activating T-lymphocytes. T-cell activation involves several different receptors on the T-cell interacting with their ligands on the antigen-bearing cell and with cytokines. We are analyzing the contributions of the various receptors to cell-cell adhesion, signal generation and activation of proliferation and differentiation programs using artificial membrane constructs having purified ligands incorporated onto their surfaces. This is allowing us to define the biochemical signaling events (kinase activation, Ca²+ changes, lipid hydrolysis, etc.) contributed by each receptor and examine the cooperative effects of engaging multiple receptors. In related work, we are using methods of cellular immunology to determine the qualitative and quantitative functional consequences of activating T cells with defined ligands in both in vitro and in vivo model systems. New insights into the requirements for T cell activation gained in these studies are being applied to the development of novel approaches to tumor immunotherapy in both murine models and clinical trials.
