Research/Clinical Interest
Title
Intestinal Immune Regulation in Health and Disease
Description
Crohn’s disease and ulcerative colitis, the two main types of inflammatory bowel disease (IBD), are believed to be due in part to a failure of intestinal immune regulation. This allows for aberrant pro-inflammatory responses to specific microbial communities that colonize the gastrointestinal tract. The adaptive immune system is actively involved in preventing such responses through the collective functions of anti-commensal antibody-secreting cells (ASCs) and CD4+ regulatory T cells (Treg cells). However, this immunoregulatory apparatus sometimes fails, predisposing to chronic intestinal inflammation. The overall goals of our research program are (1) to elucidate the mechanisms that synergize to maintain this state of intestinal immune homeostasis, and (2) to define the cellular and molecular pathways that enhance regulatory T cell function particularly during chronic inflammation and (3) to elucidate mechanisms related to psychosocial stress in early life impact susceptibility to IBD.
