Expression of lymphocyte-endothelial receptor-ligand pairs, α4β7/MAdCAM-1 and OX40/OX40 ligand in the colon and jejunum of patients with inflammatory bowel disease

Abstract

The expression of MAdCAM-1 and OX40 ligand on gut endothelial and OX40+ cells is increased in sites of mucosal inflammation in patients with inflammatory bowel disease. No evidence was found for increased lamina propria T cells or increased vascular adhesion molecule expression in the proximal intestine of patients with distal inflammatory bowel disease.
