Summary

It has long been recognized that binding of von Willebrand factor (vWf) by the platelet membrane glycoprotein (GP) Ib-IX-V complex initiates the cascade of events leading to thrombosis and haemostasis. In the last several years, however, it has become apparent that the GP Ib-IX-V complex plays a much broader role in vascular biology, a recognition in part due to the identification of novel adhesive ligands for GP Ib-IX-V such as P-selectin and Mac-1. Binding of vWf by the GP Ib-IX-V complex is also important in formation of the developing thrombus. Platelets can utilize the GP Ib-IX-V complex and PSGL-1 to roll on activated endothelium via surface-expressed endothelial P-selectin. The GP Ib-IX-V complex can bind the I domain of Mac-1, a binding interaction potentially relevant to transmigration of macrophages through mural thrombus, a process required for vessel remodeling post angioplasty. This review will focus on recent advances in our understanding of the structure and function of this important platelet receptor, with particular emphasis on insights made within the last two years.
