Binding of integrin alpha-4-beta-7 to mucosal addressin cell adhesion molecule-1 (MAdCAM-1)1 on intestinal endothelial cells is required for the homing of naive lymphocytes to Peyer's patches (Butcher & Picker 1996)
. Alpha 4 beta 7 integrin mediates lymphocyte binding to the mucosal vascular addressin MAdCAM-1 (Berli et al. 1993)
. (Arihiro et al. 2002)
observed a differential expression of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) in ulcerative colitis and Crohn's disease. (Feagan et al. 2005)
showed that antibodies to integrin alpha-4-beta-7 induce remission of ulcerative colitis in humans.
