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 ...

Clustering of glycoprotein VI (GPVI) dimers upon adhesion to collagen as a mechanism to regulate GPVI signaling in platelets [PDF]

Journal of Thrombosis and Haemostasis, 2017
Essentials - Dimeric high-affinity collagen receptor glycoprotein VI (GPVI) is present on resting platelets. - Spatio-temporal organization of platelet GPVI-dimers was evaluated using advanced microscopy. - Upon platelet adhesion to collagenous substrates, GPVI-dimers coalesce to form clusters.

Myricetin, the main flavonoid in Syzygium cumini leaf, is a novel inhibitor of platelet thiol isomerases PDI and ERp5 [PDF]

, 2020
Background: Flavonoids have been characterized as a prominent class of compounds to treat thrombotic diseases through the inhibition of thiol isomerases. Syzygium cumini is a flavonoid-rich medicinal plant that contains myricetin and gallic acid.

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 ...

The tyrosine phosphatase CD148 is an essential positive regulator of platelet activation and thrombosis [PDF]

, 2009
Platelets play a fundamental role in hemostasis and thrombosis. They are also involved in pathologic conditions resulting from blocked blood vessels, including myocardial infarction and ischemic stroke.

Phosphorylation of CLEC-2 is dependent on lipid rafts, actin polymerization,secondary mediators, and Rac [PDF]

, 2010
The C-type lectin-like receptor 2 (CLEC-2)activates platelets through Src and Syk tyrosine kinases via a single cytoplasmic YxxL motif known as a hem immunoreceptor tyrosine-based activation motif (hemITAM).Here, we demonstrate using sucrose gradient ...

Restrained glycoprotein VI-induced platelet signaling by tyrosine protein phosphatases independent of phospholipase Cγ2

Bleeding, Thrombosis and Vascular Biology, 2023
The platelet collagen receptor glycoprotein VI (GPVI) signals to activation of phospholipase Cγ2 (PLCγ2) and phosphoinositide 3-kinases (PI3K), causing platelet activation and aggregation.

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.

Immobilized fibrinogen activates human platelets through GPVI [PDF]

, 2018
GPVI, a major platelet activation receptor for collagen and fibrin, is considered as a particularly promising safe antithrombotic target. In this study, we show that human GPVI signals upon platelet adhesion to fibrinogen.
