Absence of bleeding upon dual antiplatelet therapy in a patient with a immune GPVI deficiency

Platelets, 2021
Acquired deficiencies in platelet glycoprotein VI are rare and have not been found associated with other defects. Here we report the case of a 64-year old male patient presenting an immune GPVI deficiency associated to a mutation in the alpha-actinin ...

Association between endometriosis, infertility and autoimmune antiplatelet glycoprotein VI antibodies in two patients

Platelets, 2023
The association between endometriosis and autoimmune diseases is well known, however no acquired platelet function defect has been described so far. We describe the case of two patients with endometriosis associated with an antiplatelet glycoprotein VI ...

Differential roles for the adapters Gads and LAT in platelet activation by GPVI and CLEC-2 [PDF]

, 2008
Background: The adapter proteins SLP-76 and LAT have been shown to play critical roles in the activation of PLCc2 in platelets downstream of GPVI/FcRc and the C-type lectin receptor CLEC-2.

Inhibition of Src but not Syk causes weak reversal of GPVI-mediated platelet aggregation measured by light transmission aggregometry

Platelets, 2022
Src tyrosine kinases and spleen tyrosine kinase (Syk) have recently been shown to contribute to sustained platelet aggregation on collagen under arterial shear.

Targeting GPVI as a novel antithrombotic strategy

Journal of Blood Medicine, 2014
While platelet activation is essential to maintain blood vessel patency and minimize loss of blood upon injury, untimely or excessive activity can lead to unwanted platelet activation and aggregation. Resultant thrombosis has the potential to block blood vessels, causing myocardial infarction or stroke. To tackle this major cause of mortality, clinical

Cross-Linking GPVI-Fc by Anti-Fc Antibodies Potentiates Its Inhibition of Atherosclerotic Plaque- and Collagen-Induced Platelet Activation

JACC: Basic to Translational Science, 2016
To enhance the antithrombotic properties of recombinant glycoprotein VI fragment crystallizable (GPVI-Fc), the authors incubated GPVI-Fc with anti-human Fc antibodies to cross-link the Fc tails of GPVI-Fc.

Targeting GPVI

, 2023
Platelets are blood cells that prevent the loss of extensive blood volumes, but also contribute to arterial thrombosis. After a vessel is injured, platelets become activated by the exposed collagen and aggregate together, forming a thrombus. Whilst this is a crucial process in hemostasis, platelets also become activated due to rupture of an ...

Collagen-dependent platelet dysfunction and its relevance to either mitochondrial ROS or cytosolic superoxide generation: a question about the quality and functional competence of long-stored platelets

Thrombosis Journal, 2020
Background Upon vascular damage, the exposed subendothelial matrix recruits circulating platelets to site of injury while inducing their firm adhesion mainly via GPVI-collagen interaction.
