Contribution of von Willebrand factor to thrombus formation on neointima of rabbit stenotic iliac artery under high blood-flow velocity.
OBJECTIVE It has become clear that von Willebrand factor (vWF) plays important roles in platelet adhesion and aggregation under high blood-flow velocity conditions observed in stenotic atherosclerotic arteries. However, its roles in thrombus formation in vivo on diseased arteries have not been fully understood. We examined the contribution of vWF to thrombus formation and subsequent intimal gro...
متن کاملInvolvement of glycoprotein VI in platelet thrombus formation on both collagen and von Willebrand factor surfaces under flow conditions.
BACKGROUND We studied the role of glycoprotein (GP) VI in platelet adhesion and thrombus formation on the immobilized collagen and von Willebrand factor (vWF) surface under flow conditions. METHODS AND RESULTS Whole blood obtained from 2 patients with GP VI-deficient platelets and the effects of the Fab of anti-GP VI antibody (Fab/anti-GP VI) were tested. Blood containing platelets rendered f...
متن کاملAtherosclerotic geometries exacerbate pathological thrombus formation poststenosis in a von Willebrand factor-dependent manner.
Rupture of a vulnerable atherosclerotic plaque causes thrombus formation and precipitates cardiovascular diseases. In addition to the thrombogenic content of a plaque, also the hemodynamic microenvironment plays a major role in thrombus formation. How the altered hemodynamics around a plaque promote pathological thrombus formation is not well understood. In this study, we provide evidence that ...
متن کاملMechanism of platelet adhesion to von Willebrand factor and microparticle formation under high shear stress.
We describe here the mechanism of platelet adhesion to immobilized von Willebrand factor (VWF) and subsequent formation of platelet-derived microparticles mediated by glycoprotein Ibalpha (GPIbalpha) under high shear stress. As visualized in whole blood perfused in a flow chamber, platelet attachment to VWF involved one or few membrane areas of 0.05 to 0.1 microm(2) that formed discrete adhesio...
متن کاملReal-time analysis of shear-dependent thrombus formation and its blockade by inhibitors of von Willebrand factor binding to platelets.
Two likely mechanisms for the initiation of arterial platelet thrombus formation under conditions of elevated fluid shear stresses are: (1) excessive adhesion and aggregation of platelets from rapidly flowing blood onto the exposed sub-endothelium of injured, atherosclerotic arteries; or (2) direct, fluid shear stress-induced aggregation of platelets in constricted arteries with intact endothel...
