PLATELETS AND THROMBOPOIESIS Platelet-associated IgAs and impaired GPVI responses in platelets lacking WIP

The role of the Wiskott-Aldrich syndrome protein (WASp) in platelet function is unclear because platelets that lack WASp function normally. WASp constitutively associates with WASp-interacting protein (WIP) in resting and activated platelets. The role of WIP in platelet function was investigated using mice that lack WIP or WASp. WIP knockout (KO) platelets lack WASp and thus are double deficien...

HEMOSTASIS, THROMBOSIS, AND VASCULAR BIOLOGY GPVI levels in platelets: relationship to platelet function at high shear

We have investigated the density of the collagen receptors glycoprotein VI (GPVI) and 2 1 on human platelets and their relationship to polymorphisms within the GPVI gene. GPVI levels varied 1.5-fold and showed a weak correlation (r 0.35) with the levels of 2 1, which varied 3-fold. GPVI genotype had a significant effect on receptor levels with carriers of the proline 219 allele (approximately 2...

Impaired Anaphylactic Responses with Intact Sensitivity to Endotoxin in Mice Lacking a Platelet-activating Factor Receptor

Platelet-activating factor (PAF) is a potent phospholipid mediator with diverse biological activities in addition to its well-known ability to stimulate platelet aggregation. Pharmacologic studies had suggested a role for PAF in pregnancy, neuronal cell migration, anaphylaxis, and endotoxic shock. Here we show that disruption of the PAF receptor gene in mice caused a marked reduction in systemi...

Platelets and Arterial Thrombosis: Evolving Role of Platelet GPVI as an Antithrombotic Drug Target

Acute coronary syndrome is one of the leading causes of mortality and morbidity worldwide. Although the recent advancements in existing anti-platelet therapeutics have significantly reduced the burden of cardiovascular deaths but owing to their global impact on primary haemostasis, their clinical benefits are often limited by bleeding risk. Recent developments in the understanding of platelet b...
