A team of Emory University pathologists has discovered that non-pathogenic bacteria within the gastrointestinal tract may be responsible for blocking an immune pathway that otherwise could cause an unhealthy inflammatory response to the millions of bacteria normally present in the intestine. A breakdown in this mechanism for bacterial tolerance could play a fundamental role in the pathogenesis of inflammatory bowel disease (Crohn's disease and ulcerative colitis) and other infectious intestinal diseases. The research was reported in the September 1 issue of the journal Science.
