PURPOSE OF REVIEW: The purpose of this article is to describe the function of the vascular cell adhesion and signaling molecule, platelet/endothelial cell adhesion molecule-1 (PECAM-1), in endothelial cells, with special emphasis on its role in maintaining and restoring the vascular permeability barrier following disruption of the endothelial cell junction.
RECENT FINDINGS: In addition to its role as an inhibitory receptor in circulating platelets and leukocytes, PECAM-1 is highly expressed at endothelial cell-cell junctions, where it functions as an adhesive stress-response protein to both maintain endothelial cell junctional integrity and speed restoration of the vascular permeability barrier following inflammatory or thrombotic challenge.
SUMMARY: Owing to the unique ability of antibodies that bind the membrane proximal region of the extracellular domain to trigger conformational changes leading to affinity modulation and homophilic adhesion strengthening, PECAM-1 might be an attractive target for treating vascular permeability disorders.
