Abstract

The incidence of inflammatory bowel disease, an often debilitating disorder, is increasing. Recent data indicate that complex interactions between the commensal gut microbiota, genetic and epigenetic factors and mucosal immunity are important in pathogenesis. Ongoing studies into these interactions will continue to advance understanding of processes responsible for the development of inflammatory bowel disease, as well as inform new and more effective approaches to management.
