Loss of integrity of the intestinal epithelium plays a key pathogenic role in inflammatory bowel disease (IBD). Changes in the composition of the intestinal microbiota are an important environmental factor in the development of IBD. Detrimental changes in the intestinal microbiota induce an inappropriate (uncontrolled) immune response that results in damage to the intestinal epithelium.
