Membrane Glycoproteins in Cryopreserved Platelets
Vox Sanguinis, 1994AbstractAlthough platelets stored by cryopreservation are effective in hemostasis, they acquire a number of functional defects during storage and preparation for transfusion. In addition to known acquired defects such as defective aggregation, decreased resistance to hypotonic shock, and disc‐spherocyte transformation, we have shown that cryopreserved ...

New polymorphism of platelet membrane glycoproteins
Nature, 1977THE surface of the human blood platelet is rich in carbohydrate and at least four glycoprotein components have been resolved by gel electrophoresis of isolated platelet plasma membranes1. Two platelet disease states are characterised by a diminution or absence of certain of these glycoproteins2–5: in the case of Bernard-Soulier disease, glycoprotein I (

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 ...

Platelet Membrane Glycoproteins: Functions in Cellular Interactions
Annual Review of Cell Biology, 1990The understanding of the structure and function of platelet membrane glycoproteins has been facilitated by studies showing that they belong to larger gene families of cell surface receptors involved in cellular interactions. In some instances (e.g. GP IIb-IIIa and GP Ib-IX) the study of the platelet proteins has served as a prototype for relatively ...

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 ...

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

Thrombin interaction with platelet membrane glycoprotein Ibα
Trends in Molecular Medicine, 2003The interaction of thrombin with platelet glycoprotein Ibalpha (GPIb alpha) is required for optimal platelet activation. The crystal structures of platelet GPIb alpha bound to thrombin reported by Dumas et al. and Celikel et al. both reveal the simultaneous interaction of GPIb alpha with thrombin exosites I and II but differ markedly regarding how the ...

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 ...
