VWF, Platelets and the Antiphospholipid Syndrome [PDF]

International Journal of Molecular Sciences, 2021
The antiphospholipid syndrome (APS) is characterized by thrombosis and/or pregnancy morbidity with the persistent presence of antiphospholipid antibodies (aPLs). Laboratory criteria for the classification of APS include the detection of lupus anticoagulant (LAC), anti-cardiolipin (aCL) antibodies and anti-β2glycoprotein I (aβ2GPI) antibodies.

Clinical significance of assessing ADAMTS-13 and von Willebrand factor level in COVID-19 convalescent pregnant women

Акушерство, гинекология и репродукция, 2023
Introduction. Coronavirus infection is associated with severe endotheliopathy, thromboinflammation and immunothrombosis leading to excessive release of von Willebrand factor (vWF) multimers from Weibel–Palade bodies, which can affect activity of ADAMTS ...

Inherited ADAMTS13 mutations associated with Thrombotic Thrombocytopenic Purpura: a short review and update

Platelets, 2023
ADAMTS13 is a plasma metalloprotease with the primary function of cleaving VWF to maintain hemostasis. Circulating ADAMTS13 is in the closed conformation until blood vessel injury triggers a VWF-dependant activation to the open active form of the protein.

Arf GTPase-activating proteins SMAP1 and AGFG2 regulate the size of Weibel-Palade bodies and exocytosis of von Willebrand factor

Biology Open, 2021
Arf GTPase-Activating proteins (ArfGAPs) mediate the hydrolysis of GTP bound to ADP-ribosylation factors (Arfs), which are critical to form transport intermediates.

VWF-pHluorin acts as an intraluminal pH-indicator for WPB.

, 2022
HUVEC cotransfected with P-sel-lum-mRFP and VWF-phluorin were incubated with 40 mM NH4Cl for 3 h and then analyzed by live cell confocal microscopy. Shown are images of maximum intensity projections of z-stacks. Cell circumferences are indicated by lines.

Functioning of the ADAMTS-13/vWF axis and its clinical significance

Акушерство, гинекология и репродукция, 2023
Advances in biology have allowed us to substantially deepen our knowledge about hemostasis functioning both in health and disease. ADAMTS-13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif, member 13) and von Willebrand factor (vWF)

Clinical significance of ADAMTS-13/vWF axis in pregnant women at different trimesters of gestation

Акушерство, гинекология и репродукция, 2023
Introduction. The pandemic of a novel coronavirus infection has demonstrated the importance of assessing the ADAMTS-13/vWF axis in patients with COVID-19, because a decline in this ratio mirrors disease severity.

VWF and complement [PDF]

Blood, 2015
In this issue of Blood , Feng and coworkers present data suggesting a role for von Willebrand factor (VWF) in the proteolytic inactivation of complement C3b by factor I (CFI).[1][1] Whereas smaller VWF multimers, especially dimers, tetramers, and hexamers, enhance C3b inactivation by CFI, large ...

Levels of von Willebrand factor antigen and von Willebrand factor cleaving protease (ADAMTS13) activity predict clinical events in chronic heart failure. [PDF]

, 2009
Decreased activity of ADAMTS13, the von Willebrand factor (VWF) cleaving protease, was recently reported in cardiovascular diseases and in hepatic failure.
