Project: Graft versus host disease (GVHD) is a chronic and debilitating systemic inflammatory disease characterized by inflammatory cell recruitment to the skin, gastrointestinal tract and other organs, and leads to a systemic chronic debilitating disease. Identification, characterization and potential uses of CD4+CD25+ regulatory T cells (Tregs) in the prevention of autoimmune/inflammatory diseases such as GVHD, is an important therapeutic approach. Although the etiology of GVHD is reasonably well understood, and the sequence of events underlying the course of the disease is well researched, no good approaches to therapy of this disease have been developed. By using a gene identification molecular approach, we believe that new targets of therapeutic intervention can be developed through deciphering the genetic signature of Tregs.
My project involves: (1) Identification the core set of CD4+CD25+ Treg genes by performing cDNA comparative microarray analysis of CD4+CD25+ vs CD4+CD25-T cells from the thymus and spleen of BALB/c and B6 mice at several different time points (age) to identify the shared core set of expressed Treg genes: ‘the core Treg transcriptome’, (2) Validation of the ‘core transcriptome’ genes based on in vitro loss-of-function studies using functional genomics (RNAi), (3) Investigating the in vivo loss of function of genes tested in (2) above using a model of GVHD. If these studies are successful in demonstrating a Treg core transcriptome, a similar approach can be taken with human Tregs to identify genes associated with loss of function in studies in vitro. (4) Identification of lineage specific genes that are involved in the development of T regulatory cells.

Project:
Type 1 Diabetes develops due to the lack of T cell tolerance to islet
antigens. T cells which recognize self-antigen are normally deleted
through central or peripheral tolerance mechanisms. Central tolerance
occurs in the thymus as developing T cells are exposed to self-antigens
expressed in medullary thymic epithelial cells. Peripheral tolerance
occurs when mature T cells circulate through the body and encounter
peripheral tissue antigens on various cells, including those of the
lymph nodes. My work focuses on the identification and characterization
of genes which regulate peripheral tissue antigen expression and peripheral
tolerance during the development of Type I diabetes.
