Genetic evidence for functional redundancy of Platelet/Endothelial cell adhesion molecule-1 (PECAM-1): CD31-deficient mice reveal PECAM-1-dependent and PECAM-1-independent functions.
Platelet/endothelial cell adhesion molecule-1 (PECAM-1; CD31), a member of the Ig superfamily, is expressed strongly at endothelial cell-cell junctions, on platelets, and on most leukocytes. CD31 has been postulated to play a role in vasculogenesis and angiogenesis, and has been implicated as a key mediator of the transendothelial migration of leukocytes. To further define the physiologic role ...
متن کاملPlatelet Endothelial Cell Adhesion Molecule-1 (PECAM-1) Homophilic Adhesion Is Mediated by Immunoglobulin-like Domains
PECAM-1/CD31 is vascular cell adhesion and signaling molecule of the Ig superfamily that plays a role in neutrophil recruitment at inflammatory sites and may be involved the release of leukocytes from the bone marrow and in cardiovascular development. The interactions of PECAM-1 with its ligands are complex in that it is able to bind both with itself (homophilic adhesion) or with non-PECAM-1 li...
متن کاملPlatelet PECAM-1 inhibits thrombus formation in vivo.
Platelet endothelial cell adhesion molecule-1 (PECAM-1) is a cell surface glycoprotein receptor expressed on a range of blood cells, including platelets, and on vascular endothelial cells. PECAM-1 possesses adhesive and signaling properties, the latter being mediated by immunoreceptor tyrosine-based inhibitory motifs present on the cytoplasmic tail of the protein. Recent studies in vitro have d...
متن کاملIn vivo regulation of PECAM-1 activity during acute endothelial dysfunction in the rat mesenteric microvasculature.
The relationship between acute endothelial dysfunction and the extravasation of leukocytes was studied in vivo with intravital microscopy of the rat mesenteric microvasculature. Acute endothelial dysfunction of the rat mesenteric microvasculature was induced in vivo by superfusing the mesentery for 90 min with one of three different stimulating agents: NG-nitro-L-arginine methyl ester (L-NAME, ...
متن کاملAssociation of Leu125Val polymorphism of platelet endothelial cell adhesion molecule-1 (PECAM-1) gene & soluble level of PECAM-1 with coronary artery disease in Asian Indians.
BACKGROUND & OBJECTIVES Platelet endothelial cell adhesion molecule-1 (PECAM-1) plays a key role in the transendothelial migration of circulating leukocytes (diapedesis) during vascular inflammation. We hypothesized that genetic variation and the level of soluble PECAM-1 could be associated with the development of atherosclerosis and conducted a study on gene polymorphisms of PECAM-1 and solubl...
