title: Platelet-leukocyte-endothelial cell interaction on the blood vessel wall.
abstract: Leukocytes, platelets, and endothelial cells interact at sites of vascular injury and inflammation through adhesion receptors on the cell surface. On binding of ligand to receptor, these receptors initiate intracellular signaling that leads to the modulation of several biological properties of the cells involved. These finely regulated processes involve several classes of cell adhesion molecules: integrins, immunoglobulin-like proteins, selectins, and mucin-like proteins as well as an array of soluble mediators. Interaction of these cell adhesion molecules serves to recruit circulating cells to the blood vessel endothelium or to accumulated platelets on the vessel wall and to foster cell-cell communication. The importance of these interactions to inflammation, blood coagulation, and the immune response is outlined.
