Thrombin is a physiological agonist that promotes platelet aggregation and secretion. In this study we observed that thrombin can also inhibit a function of platelets related to primary hemostasis. Platelet stimulation by thrombin decreased the binding of von Willebrand factor (vWF) to glycoprotein (GP) Ib and decreased ristocetin-induced agglutination, in vitro reactions that correlate with in...
BACKGROUND Pulmonary thromboembolism (PTE) is among the leading causes of death following surgery and/or hospital admission. Role of thrombophilic risk factors in the etiology of PTE is well known; But not much data is available on their role in severity of PTE. The aim of this study was to investigate the role of thrombotic risk factors especially PLA2 polymorphism of platelet glycoprotein IIb...
Background—The major platelet integrin glycoprotein IIb-IIIa plays a primary role in platelet aggregation and acute thrombus formation at the site of vascular injury. A genetic polymorphism of glycoprotein IIb-IIIa (Pl) has recently been proposed as a potential genetic factor linking to platelet hyperaggregability and increased risk of myocardial infarction. Despite numerous, mostly nonprospect...
BACKGROUND The major platelet integrin glycoprotein IIb-IIIa plays a primary role in platelet aggregation and acute thrombus formation at the site of vascular injury. A genetic polymorphism of glycoprotein IIb-IIIa (Pl(A)) has recently been proposed as a potential genetic factor linking to platelet hyperaggregability and increased risk of myocardial infarction. Despite numerous, mostly nonprosp...
BACKGROUND Inhibitors of the platelet glycoprotein IIb/IIIa receptor given intravenously have been shown to be effective in reducing ischemic complications after coronary angioplasty and in unstable angina, making this a promising new class of agents for the treatment and prevention of ischemic events in patients with acute coronary syndromes. Sibrafiban (Ro 48-3657) is an oral, peptidomimetic,...
BACKGROUND AND PURPOSE Intraprocedural thrombus formation during endovascular treatment of intracranial aneurysms is often treated with glycoprotein IIb/IIIa inhibitors and, in some instances, fibrinolytic therapy. We performed a meta-analysis evaluating the safety and efficacy of GP IIb/IIIa inhibitors compared with fibrinolysis. We also evaluated the safety and efficacy of abciximab, an irrev...
Data on the agreement between aggregometry and platelet activation by flow cytometry regarding the measurement of on-treatment platelet reactivity to arachidonic acid (AA) and adenosine diphosphate (ADP) are scarce. We therefore sought to compare three platelet aggregation tests with flow cytometry for the assessment of the response to antiplatelet therapy. Platelet aggregation in response to A...
The purification, complete amino acid sequence, and biological activity are described for several homologous snake venom proteins that are platelet glycoprotein (GP) IIb-IIIa antagonists and potent inhibitors of platelet aggregation. The primary structures of kistrin (from Agkistrodon rhodostoma), bitan (from Bitis arietans), three isoforms of trigramin (from Trimeresusus gramineus), and an iso...
B ivalirudin and cangrelor are 2 intravenous drugs, 1 for anticoagulation and the other for antiplatelet therapy, with a rapid onset of action, thus in theory perfectly adapted to percutaneous coronary intervention (PCI) that requires simultaneous thrombin and platelet inhibition. These effects are especially needed for mechanical coronary reperfusion of acute patients such as those presenting ...
RATIONALE Multiple sclerosis (MS) and its mouse model, experimental autoimmune encephalomyelitis (EAE), are inflammatory disorders of the central nervous system (CNS). The function of platelets in inflammatory and autoimmune pathologies is thus far poorly defined. OBJECTIVE We addressed the role of platelets in mediating CNS inflammation in EAE. METHODS AND RESULTS We found that platelets w...
