Platelet-collagen interactions: increase in rate of adhesion of fixed washed platelets by factor VIII-related antigen.
A simple technique using an aggregometer and fixed washed human platelets (FWP) and fibrillar collagen has been used to evaluate the contribution of the two components of the factor VIII (FVIII) complex to platelet-collagen interactions. FWP bound individually to collagen fibrils in suspension, and both the total number of FWP bound and the rate of adhesion increased with increasing collagen co...
متن کاملFactor VIII/von Willebrand factor in subendothelium mediates platelet adhesion.
The present studies were undertaken to determine whether factor VIII/von Willebrand factor (vWF) present in the vessel wall (in addition to that in plasma) may mediate the attachment of platelets to subendothelium. Subendothelium from everted rabbit aorta was exposed to human citrated blood flowing through an annular perfusion chamber at 40 mL/min (wall shear rate of 2,600 s-1 for five minutes)...
متن کاملSubcellular platelet factor VIII antigen and von Willebrand factor
Subcellular membrane and granule fractions derived from human platelets contain factor VIIII antigen and von Willebrand factor activity but not factor VII procoagulant activity. Circulating platelets constitute a significant reservoir of plasma factor VIII antigen, containing approximately 15% of the amount of factor VIII antigen present in platelet-poor plasma. The antibiotic ristocetin, which...
متن کاملPlatelet Adhesion to Collagen and Collagen-Related Peptide Under Flow
Objective—Platelet stimulation by collagen and collagen-related peptides (CRPs) is associated with activation of protein tyrosine kinases. In the present study, we investigated the role of Src family tyrosine kinases in the initial adhesion events of human platelets to collagen and cross-linked CRP. Methods and Results—Under arterial flow conditions, a glycoprotein VI–specific substrate, cross-...
