Platelet von Willebrand Factor
Mayo Clinic Proceedings, 1991von Willebrand factor (vWF) circulates in the blood in two distinct compartments. One, plasma vWF, is synthesized and released from endothelial cells; the second, synthesized by megakaryocytes, circulates in platelets primarily stored in the alpha granules.

von Willebrand Factor and Aging
Seminars in Thrombosis and Hemostasis, 2014von Willebrand factor (VWF) plays critical roles in initiating primary hemostasis and extending the half-life of coagulation factor VIII in circulation. VWF levels increase with age and elevated levels are associated with an increased risk of venous thromboembolism and cardiovascular disease (CVD).

Von Willebrand factor multimer patterns in von Willebrand's disease
British Journal of Haematology, 1983Summary. The von Willebrand factor antigen (factor VIII‐related antigen, VIIIR:Ag) multimer pattern has been analysed by SDS‐agarose electrophoresis of plasmas from 116 patients (47 families) with von Willebrand's disease. In addition to previously recognized patterns, a subclassification was established between plasmas that had a type Ia pattern ...

Von Willebrand factor/factor VIII concentrates in the treatment of von Willebrand disease
Blood Coagulation & Fibrinolysis, 2009Therapy for von Willebrand disease (VWD) aims to restore the hemostatic function conferred by von Willebrand factor (VWF), which facilitates platelet adhesion and aggregation, and serves to increase potentially low coagulation factor VIII (FVIII) in plasma. In patients unresponsive to desmopressin (DDAVP), the preferred treatment is with plasma-derived

Von Willebrand factor processing
Hämostaseologie, 2017SummaryVon Willebrand factor (VWF) is a multimeric glycoprotein essential for primary haemostasis that is produced only in endothelial cells and megakaryocytes. Key to VWF’s function in recruitment of platelets to the site of vascular injury is its multimeric structure.

von Willebrand Factor, von Willebrand Factor-Cleaving Protease, and Shear Stress
Cardiovascular & Hematological Agents in Medicinal Chemistry, 2007von Willebrand factor (VWF) is a multimeric plasma glycoprotein (GP) involved in platelet adhesion at the site of vascular damage, which acts as a bridge between the injured subendothelium and the platelet receptors. The multimeric structure of VWF allows it to support multiple interactions with platelets and endothelial components under high shear ...

A rapid assay for von willebrand factor
Thrombosis Research, 1987Multiple assays have been described which quantify von Willebrand Factor (vWF) in plasma or other specimens. An assay using a modification of the microtitre method(1) is described. Washed platelets fixed in formalin and frozen in dimethylsulfoxide are substrate for the reaction.

Von Willebrand factor and fibrinogen
Current Opinion in Cell Biology, 1993Progress in understanding the structure and function of von Willebrand factor and fibrinogen has provided new insights into the mechanisms of hemostasis and thrombosis. This, in turn, has generated concepts that may become applicable to the diagnosis and treatment of occlusive vascular diseases and bleeding disorders, both congenital and acquired.

The von Willebrand Factor Gene and Genetics of von Willebrand's Disease
Mayo Clinic Proceedings, 1991The von Willebrand factor (vWF) gene spans 178 kilobases in the human genome, is interrupted by 51 introns, and has been localized to human chromosome 12p12----12pter. In addition, a pseudogene that duplicates the midportion of the vWF gene has been identified on chromosome 22.
