Research Interests:

Signal transduction, lymphocyte activation, cell adhesion and migration

The generation of an antigen-specific immune response requires the coordinated interaction of the various cellular constituents of the immune system with each other and with components of the extracellular environment found in tissue.  These adhesive events are critical to the efficient trafficking of lymphocytes through the body, the interaction of T lymphocytes with antigen-presenting cells that initiates and sustains T cell activation, and the influx of leukocytes into sites of inflammation. Dr. Shimizu's laboratory is investigating the intracellular signal transduction events that regulate the strength of these adhesive interactions and the functional significance of these molecular mechanisms of cell adhesion and migration on the ability of the immune system to respond to pathogens and tumors.  Specific areas of investigation projects include: 1) analysis of the biochemical signaling events by which the antigen-specific T cell receptor regulates the functional activity of integrins, a family of cell adhesion receptors that mediates the adhesion of cells to other cells and to extracellular matrix molecules; 2) mechanisms of receptor “cross-talk” that regulate integrin function; 3) the function of adapter proteins in regulating T cell gene transcription and cytoskeletal reorganization; 4) elucidation of pathways mediating the migration and retention of tumor-specific T cells into sites of tumor growth; and 5) analysis of the function of the lipid kinase p110gamma in regulating the inflammatory response and T cell-dependent immune responses to vaccinia virus.    Dr. Shimizu’s laboratory combines molecular and biochemical approaches with genetic models in the mouse where the impact of altering signaling pathways on the generation of antigen-specific and tumor-specific immune responses can be assessed.  The long-term objective is to provide the knowledge base necessary to specifically modulate the immune response by targeting these mechanisms of cell adhesion and migration.
