Platelet Membrane Glycoproteins
2017Platelets are small anucleate blood cells that are produced in the bone marrow from the cytoplasm of megakaryocytes. Circulating platelets are essential for primary hemostasis and also involved in pathological thrombosis. For the platelet hemostatic functions, platelet surface membrane glycoproteins are crucial to form platelet-subendothelial matrix ...

Thrombosis and Thrombolysis: Platelet Membrane Glycoproteins
Heart, Lung and Circulation, 2007Over the last quarter of a century, therapy for acute coronary syndromes has rapidly evolved. The major causative factor for acute coronary syndromes, particularly acute myocardial infarction, is now recognised to be coronary thrombosis and therapies using thrombolytic agents to dissolve thrombus or percutaneous coronary interventions (angioplasty and ...

On the role of the major platelet membrane glycoproteins in platelet adhesion to collagen
Thrombosis Research, 1981Abstract The effect of modification of intact rabbit platelets with chymotrypsin, trypsin or thrombin on platelet adhesion to collagen fibers was determined. Experiments were performed in vitro with washed platelets suspended in a medium containing EGTA to prevent platelet aggregation.

Studies on human and bovine platelet membrane glycoproteins
International Journal of Biochemistry, 1979Abstract 1. 1. We have re-evaluated the number of platelet membrane glycoproteins with use of sodium dodecyl sulfate—polyacrylamide gel electrophoresis and two highly sensitive detection techniques. 2. 2. The first involves incorporation of the fluorophore dansyi hydrazine into the carbohydrate moiety after post-electrophoresis periodate ...

Platelet membrane glycoproteins and their function: An overview
Blut, 1989The membrane glycoproteins (GP) of human platelets act as receptors that mediate two important functions, adhesion to the subendothelial matrix and platelet-platelet cohesion, or aggregation. Many of these glycoprotein receptors exist as noncovalently linked heterodimers, including those that belong to the supergene family of adhesion receptors called ...

Thrombin Interaction With Platelet Membrane Glycoprotein Ib
Seminars in Thrombosis and Hemostasis, 1996Platelet activation by low doses of thrombin allows the amplification thrombin formation and thereby plays an important role in the development of thrombi. Although thrombin-induced platelet activation is elicited via the cleavage of its specific receptor (TR), platelet membrane glycoprotein Ib (GPIb) is required for responses to low concentrations of ...

Thrombosis Research, 1989
Human platelets contain a single membrane glycoprotein which is susceptible to thrombin proteolysis, glycoprotein V. We have purified 1 mg of glycoprotein V from 10(13) platelets using a combination of gel filtration, hydroxylapatite and ion-exchange chromatographies. Glycoprotein V has a blocked amino-terminus.

Polymorphisms of Platelet Membrane Glycoproteins
2009Platelet glycoproteins (GPs) act as membrane receptors. Functions of GPs were well studied in GPIa/IIa (integrin α2β1), GPIb/IX/V, GPIIb/IIIa (integrin αIIbβ3), and GPVI. Each GP has a different role in the processes of physiological hemostasis and thrombus formation, such as platelet adhesion to the subendothelial matrix, firm adhesion with subsequent

Platelet Aggregation By Membrane Glycoprotein I
Thrombosis and Haemostasis, 1981It has been recently shown that platelet membrane components, particularly glycoproteins, have a lectin activity, thus mediating an aggregation of platelets. To obtain further evidences for a crucial role of glycoproteins in an aggregation mechanism,we have investigated the possibility that membrane glycoprotein can directly induce an aggregation of ...

Ca2+ influx and platelet membrane glycoproteins.
Nihon Ketsueki Gakkai zasshi : journal of Japan Haematological Society, 1990When aequorin-loaded platelets were stimulated with thrombin, the luminescence of aequorin showed two peaks. From experiments with 1 mM external Ca2+ or 1 mM EGTA, both one-half of the first peak and the entire second peak reflected the influx of Ca2+ from the external medium, and the remaining half of the first peak reflected the mobilization of Ca2 ...
