Regulation of plasma von Willebrand factor
Von Willebrand factor (VWF) is a multimeric plasma glycoprotein that plays a central role in the initiation of blood coagulation. Through interactions between its specific functional domains, the vascular wall, coagulation factor VIII, and platelet receptors, VWF maintains hemostasis by binding to platelets and delivering factor VIII to the sites of vascular injury. In the healthy human populat...
متن کاملRegulation of von Willebrand factor-platelet interactions.
The formation of thrombi is a multistep process involving several components, including von Willebrand factor (VWF). VWF is an adhesive multimeric protein, which acts as a molecular bridge between the subendothelial matrix and the glycoprotein Ib/IX/V receptor complex. Furthermore, VWF promotes the expansion of the platelet plug by cross-linking platelets via binding to integrin alphaIIbbeta3. ...
متن کاملProteolysis of von Willebrand factor in therapeutic plasma concentrates.
Therapeutic plasma concentrates containing vo Willebrand factor (vWF) lack the largest, most hemostatically active multimers. To evaluate whether this abnormality results from proteolysis during manufacturing, we have analyzed the subunit structure of vWF in several commercial products and found a marked reduction in the relative content of intact 225-kD subunit, paralleled by an increase in th...
متن کاملZebrafish von Willebrand factor.
von Willebrand factor (vWF) is a large protein involved in primary hemostasis. A dysfunction in this protein or an insufficient production of the protein leads to improper platelet adhesion/aggregation, resulting in a bleeding phenotype known as von Willebrand disease (vWD). To gain a better understanding of vWF interactions in vivo, the use of zebrafish as a model is ideal because of the trans...
متن کاملVon Willebrand factor.
The adhesive protein von Willebrand factor contributes to platelet function by mediating the initiation and progression of thrombus formation at sites of vascular injury. In the last 2 years, there has been considerable progress in explaining the biologic properties of von Willebrand factor. The three-dimensional structure of specific domains has been explained, with the demonstration of distin...
