PECAM-1 (CD31) function
Angiogenesis, the formation of new blood vessels from preexisting ones, is a complex process consisting of interrelationships of angiogenic, survival and differentiation factors and their receptors with cell adhesion and cell-matrix adhesion molecules (Beck and D’Amore, 1997; Folkman and D’Amore, 1996; Hanahan, 1997; Hanahan and Folkman, 1996; Risau, 1997; Sage, 1997; Stromblad and Cheresh, 199...
متن کاملRole of immunoreceptor tyrosine-based inhibitory motifs of PECAM-1 in PECAM-1-dependent cell migration.
Platelet endothelial cell adhesion molecule (PECAM-1), a transmembrane glycoprotein, has been implicated in angiogenesis, with recent evidence indicating the involvement of PECAM-1 in endothelial cell motility. The cytoplasmic domain of PECAM-1 contains two tyrosine residues, Y663 and Y686, that each fall within an immunoreceptor tyrosine-based inhibitory motif (ITIM). When phosphorylated, thes...
متن کاملPECAM-1-dependent neutrophil transmigration is independent of monolayer PECAM-1 signaling or localization.
Platelet endothelial cell adhesion molecule-1 (PECAM-1/CD31), a tyrosine phosphoprotein highly expressed on endothelial cells and leukocytes, is an important component in the regulation of neutrophil transendothelial migration. Engagement of endothelial PECAM-1 activates tyrosine phosphorylation events and evokes prolonged calcium transients, while homophilic engagement of neutrophil PECAM-1 ac...
متن کاملInfluence of PECAM‐1 ligand interactions on PECAM‐1‐dependent cell motility and filopodia extension
Platelet endothelial cell adhesion molecule (PECAM-1) has been implicated in angiogenesis through processes that involve stimulation of endothelial cell motility. Previous studies suggest that PECAM-1 tyrosine phosphorylation mediates the recruitment and then activation of the tyrosine phosphatase SHP-2, which in turn promotes the turnover of focal adhesions and the extension of filopodia, proc...
متن کاملGenetic 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 ...
