PECAM-1/CD31 was present mainly on luminal surfaces and at the junctions between endothelial cells. PMID: 10950884. CD31 is distributed over the entire endothelial cell surface, exclusive of specialized junctions, and in VVOs, but is not equally accessible to different antibodies in all locations.latelet endothelial cell adhesion molecule-1 (PECAM-1/CD31) acts as a regulator of B-cell development, B-cell antigen receptor (BCR)-mediated activation, and autoimmune disease.
