Dr. Goetzl's laboratory is investigating the expression of vasoactive intestinal peptide (VIP) in T cells and nerves supplying immune organs, as a mechanism for neuroregulation of hypersensitivity reactions. The nanomolar levels of VIP attained at sites of allergic reactions bind to T cell inducible G protein-coupled receptors (VPAC2 Rs) for VIP and signal T cell migration and deviation to a Th2-like phenotype. A T cell-selective VPAC2 GPCR transgenic mouse (TG) has an allergic phenotype, whereas the VPAC2 GPCR knock-out (K/O) mouse has increased delayed-type hypersensitivity, but no detectable allergy. Several carboxyl-terminal deletion mutants of VPAC2 have been identified in T cells that also favor deviation of CD4 T cells to the Th2 phenotype. Current studies are directed to defining the mechanisms of immunoregulation of expression of various types of mutant VPAC2 GPCRs and delineating immune responses of VPAC2 TG x OTII and VPAC2 K/O x OTII mice to oral vs. subcutaneous doses of their preferred peptide antigen.

Dr. Goetzl's laboratory has been elucidating the mechanisms by which the mast cell- and macrophage-derived lipid termed sphingosine 1-phosphate signals through the type 1 (S1P1) and type 4 (S1P4) G protein-coupled receptors to control T cell and B cell migration in tissues, lymphoid system homing, and other immune functions. By applying a range of novel mouse genetic models, functional, antibodies and pharmacological agents, Dr. Goetzl and his colleagues are determining the mechanisms by which the S1P-S1P GPCR axes control immunity normally and in several models of autoimmune diseases.
