-Adhesion molecules in inflammatory bowel disease: therapeutic implications for gut inflammation

Abstract\r\nMucosal endothelium has become one of the major areas of investigation in gut inflammation. It is now well recognised that it plays an active role in the pathogenesis of both forms of inflammatory bowel disease, Crohn's disease and ulcerative colitis, since endothelial cells regulate mucosal immune homeostasis, acting as "gatekeepers", controlling leukocyte accumulation in the interstitial compartment. This process is mediated by leukocyte-endothelial adhesion molecules. This paper reviews the major molecules that mediate leukocyte-endothelial interactions, and summarises the results of the most recent clinical trials targeting adhesion molecules in inflammatory bowel diseas
