Background

Platelet endothelial cell adhesion molecule-1 (PECAM-1, CD31) is a member of the immunoglobulin gene superfamily of cell adhesion molecules. CD31 is a transmembrane glycoprotein that is highly expressed on the surface of the endothelium, making up a large portion of its intracellular junctions. CD31 is also present on the surface of hematopoietic cells and immune cells, including platelets, monocytes, neutrophils, natural killer cells, megakaryocytes, and some types of T-cells. In addition to its role in cell-cell adhesion, CD31 serves as a signaling receptor and is involved in crucial physiological events, including nitric oxide production, regulation of T-cell immunity and tolerance, leukocyte transendothelial migration, and inflammation and angiogenesis.
