| Abstract |

dysregulated immune responses against intraluminal bacterial antigens. Recently, numerous new genes have been identified as involved in the genetic susceptibility to ulcerative colitis, including IL-23R, MST1, IL-12B (p40), NKX2-3, and STAT3. Experimental studies of ulcerative colitis point to an excessive T-cell response to antigenic stimulus resulting in damage to host intestinal tissue. The T-cell response in ulcerative colitis appears to be TH2 dominant (IL-5, IL-13) and mediated by specialized cells, such as NK T-cells. The characterization of these novel genes and immunologic basis should lead to the identification of therapeutic agents and a better clinical assessment of phenotype and prognosis in patients with ulcerative colitis. |
