von Willebrand factor and its relevance to cardiovascular disorders.
In the past decade the importance of the vascular endothelium in cardiovascular pathophysiology has become more apparent. One substance that is synthesised by and stored in endothelial cells is von Willebrand factor (vWF). When released, vWF seems to mediate platelet aggregation and adhesion to the vascular endothelium. Because the release of vWF is increased when endothelial cells are damaged,...
متن کاملPlatelet von Willebrand factor in inherited and acquired bleeding disorders.
The majority of plasma proteins involved in the mechanisms of hemostasis are loosely adsorbed on the platelet surface. A few of them, however, can also be measured in washed platelets, in which they are contained in the intracellular organelles called a granules. The main proteins involved in blood coagulation concentrated in platelets are von Willebrand factor (vWF), fibrinogen, and factor V. ...
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 کاملDecreased von Willebrand factor protease activity associated with thrombocytopenic disorders.
Recent studies investigating thrombotic thrombocytopenic purpura (TTP) have implicated abnormal plasma von Willebrand factor (vWF)-cleaving metalloprotease activity in this disorder. It has been proposed that a metalloprotease cleaves unusually large (UL) multimers of vWF, which enter the circulation from the endothelium. Abnormal metalloprotease activity could result in ULvWF, which could part...
متن کاملCorrelation of circulating von Willebrand factor levels with cardiovascular hemodynamics.
BACKGROUND Valvular heart disease is associated with a decreased platelet circulating time and a thrombotic tendency. The possibility that these events are related to changes in von Willebrand factor (vWF), a multimeric glycoprotein released from endothelial cells and platelets that mediates platelet adhesion to the vascular subendothelium, has not been examined. METHODS AND RESULTS We measur...
