Research Interests

Our research is focused on the pathogenesis of inflammatory bowel disease (IBD). The approach we adopted is the investigation of immune events occurring in the bowel of Crohn's disease and ulcerative colitis patients, as well as animal models of IBD. Our studies include the identification of mechanisms of mucosal T-cell death and survival in gut inflammation, investigation of tolerance of mucosal T-cells for the autologous enteric flora and its possible loss in IBD, characterization of the interactions between mucosal T-cells and endothelial and stromal cells, and the study of immune-driven angiogenesis in intestinal inflammation.

Experiments are carried out using mononuclear cells isolated from the intestinal mucosa, especially T cells and T cell subsets, epithelial cells, microvascular endothelial cells, myofibroblasts and stromal cell-derived extracellular matrix.We have recently developed novel technique to isolate and grow intestinal epithelial cell organoids to test the effect of luminal contents on epithelial cell differentiation.

The overall goal is to uncover fundamental defects of immunoregulation that may underlie the triggering or maintenance of a chronic state of inflammation in the bowel.
