Role 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, these residues together mediate the binding of the protein tyrosine phosphatase SHP-2.

PECAM-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 activates leukocyte beta-integrins. Although PECAM-1 modulates polymorphoneutrophil transmigration via homophilic PECAM-1-PECAM-1 interaction, the mechanisms underlying endothelial PECAM-1 function are unknown.

Involvement of human PECAM-1 in angiogenesis and in vitro endothelial cell migration.

Platelet endothelial cell adhesion molecule (PECAM)-1 has been implicated in angiogenesis, but a number of issues remain unsettled, including the independent involvement of human PECAM-1 (huPECAM-1) in tumor angiogenesis and the mechanisms of its participation in vessel formation. We report for tumors grown in human skin transplanted on severe combined immunodeficiency mice that antibodies against huPECAM-1 (without simultaneous treatment with anti-VE-cadherin antibody) decreased the density of human, but not murine, vessels associated with the tumors. Anti-huPECAM-1 antibody also inhibited tube formation by human umbilical vein endothelial cells (HUVEC) and the migration of HUVEC through Matrigel-coated filters or during the repair of wounded cell monolayers.
