Mechanochemistry of von Willebrand factor [PDF]

open access: yesBiomolecular Concepts, 2019
Von Willebrand factor (VWF), a blood multimeric protein with a very high molecular weight, plays a crucial role in the primary haemostasis, the physiological process characterized by the adhesion of blood platelets to the injured vessel wall ...

Von Willebrand factor [PDF]

open access: yesClinical Medicine, 2020
Editor – Ladikou et al have elegantly shown in their series that levels of factor VIII and von Willebrand factor (VWF) are markedly raised in patients with COVID-19 and that there is a reduced level of ADAMTS13 which may be secondary to depletion of the enzyme through consumption.[1][1 ...

A novel approach to laboratory assessment and reporting of platelet von Willebrand factor

open access: yesPlatelets, 2022
The interaction of platelets with von Willebrand factor is essential for primary hemostasis. Concentration and activity of plasma von Willebrand factor are routine parameters in the assessment of hemostasis disorders. In addition to plasma von Willebrand

Carbohydrate of the Factor VIII/von Willebrand Factor in von Willebrand's Disease [PDF]

open access: yesJournal of Clinical Investigation, 1979
We have examined the plasma Factor VIII/von Willebrand factor (FVIII/vWF) molecule from 16 patients with von Willebrand's disease, and have found no evidence of a significant decrease of carbohydrate content in 15 of these patients. FVIII/vWF was isolated by preparative counter immunoelectrophoresis directly from plasma using antibody to Factor VIII ...

Cryptic non-canonical splice site activation is part of the mechanism that abolishes multimer organization in the c.2269_2270del von Willebrand factor

open access: yesHaematologica, 2020
We report a new pathogenic mechanism in von Willebrand disease involving the use of a non-canonical splicing site. The proband, carrying the homozygous c.2269_2270del mutation previously classified as a type 3 mutation, showed severely reduced plasma and

Platelet-independent adhesion of calcium-loaded erythrocytes to von Willebrand factor. [PDF]

open access: yesPLoS ONE, 2017
Adhesion of erythrocytes to endothelial cells lining the vascular wall can cause vaso-occlusive events that impair blood flow which in turn may result in ischemia and tissue damage.

Evaluation of a new semi-automated Hydragel 11 von Willebrand factor multimers assay kit for routine use [PDF]

open access: yesJournal of Medical Biochemistry, 2021
Background: Accurate diagnosis and classification of von Willebrand disease (VWD) are essential for optimal management. The von Willebrand factor multimers analysis (VWF:MM) is an integral part of the diagnostic process in the phenotypic classification ...

von Willebrand factor binds to the surface of dendritic cells and modulates peptide presentation of factor VIII

open access: yesHaematologica, 2016
It has been proposed that von Willebrand factor might affect factor VIII immunogenicity by reducing factor VIII uptake by antigen presenting cells. Here we investigate the interaction of recombinant von Willebrand factor with immature monocyte-derived ...

von Willebrand factor. [PDF]

open access: yesJournal of Clinical Investigation, 1997
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.

An apparently silent nucleotide substitution (c.7056C>T) in the von Willebrand factor gene is responsible for type 1 von Willebrand disease

open access: yesHaematologica, 2011
Background Nucleotide variations not changing protein sequences are considered silent mutations; accumulating data suggest that they can, however, be important in human diseases.Design and Methods We report an altered splicing process induced by a silent
