Leukocyte recruitment at site vascular injury with endothelial denudation and platelet deposition. Sequential adhesion cascade of leukocyte attachment to and transmigration across surface-adherent platelets involves the initial tethering and rolling of leukocytes on platelet P-selectin and is followed by firm leukocyte adhesion and transplatelet migration, processes that are dependent on leukocyte Mac-1 and platelet receptors, including GPIbα, JAM-3, and fibrinogen bound to GPIIb/IIIa.
