(Sartor, 2006). It is hypothesized that both are immunologically mediated and the inflammation cascade is started by environmental factors that break the mucosal barrier. In theory, once the mucosal barrier of the intestine is broken, the T-cells from the acquired immune response attack bacteria in individuals with genetic tendencies toward inflammatory bowel disease. For inflammatory bowel diseases to manifest it must have four contributing factors. These factors are genetic susceptibility, an immune response, environmental factors, and microbial antigens and adjuvants. These four genes have been linked to Crohn’s disease: CARD15, DLG5, PPARG, and SLC22A4 &5. Ulcerative colitis has only one associated gene: MDR1. It is thought that these genes help regulate biologic functions such as, determining the integrity of the mucosal barrier, getting rid of microbes, immunoregulation and response, and maintaining homeostasis within the intestinal wall. The
