Research Overview

  • Dr. Bucy’s research interests revolve around the regulation of immune responses by T cells, particularly the forms of regulation that develop in vivo in situations with chronic antigen presence. Conventional model systems used to understand the course of an immune response have used model antigens given in discreet inoculations so that the clearance of antigen is the dominant overall control mechanism. In physiological situations such as solid organ transplantation, chronic viral diseases, and organ specific autoimmune diseases, antigen is usually not cleared, but the immune system develops various control mechanisms that limit immune damage. A major model system is analysis of the regulatory mechanisms operative in solid organ allograft rejection, using vascularized murine heart transplants. Our lab has produced multiple novel strains of mice including TCR Transgenic lines, mice that express the relevant transplant antigen recognized by the TCR Tg T cells as a transgene, allelic markers systems to track T cells and antigen presenting cells in vivo, selected mice with knockouts of several relevant control molecules. These studies are the conditions of stimulation which give rise to suppressive functions in these TCR Tg T cells and how such suppression can block allograft rejection. In these studies, multiple techniques are used including extensive use of flow cytometry, multiple label immunofluorescence in tissue sections, in situ hybridization analysis of viral and cellular RNA species, quantitative-competitive RT-PCR, and cell culture techniques.
