974 Platelet Membrane Glycoproteins
Glycoproteins I Ib / I I Ia form a Ca2+-dependent complex that functions as the fibrinogen receptor on human platelets (1). Several reports have indicated that this fibrinogen receptor is also expressed on the surface of human monocytes (2-4). Of three monoclonal antibodies directed against platelet I Ib/ I I Ia , two were reported to give a positive reaction with monocytes as well (4). Other i...
متن کاملShear-induced platelet aggregation requires von Willebrand factor and platelet membrane glycoproteins Ib and IIb-IIIa.
Different types of platelets in various types of plasma were subjected to levels of shear stress that produce irreversible platelet aggregation in normal platelet-rich plasma (PRP). At shear stresses of 90 or 180 dyne/cm2 applied for 30 seconds or five minutes, aggregation was either absent or only transient and reversible using severe von Willebrand's disease (vWD) PRP (less than 1% von Willeb...
متن کاملPlatelet membrane glycoproteins: historical perspectives
The function of blood platelets to prevent blood loss at injured sites in the vasculature depends largely on their capacity to adhere, aggregate, promote coagulation and secrete factors that induce vasoconstriction and recruit inflammatory cells. Produced in large numbers from megakaryocytes, platelets enter the circulation for 7–10 days primed to fulfill their hemostatic function. By 1970, tho...
متن کاملPlatelet membrane glycoproteins: a historical review.
The search for the components of the platelet surface that mediate platelet adhesion and platelet aggregation began for earnest in the late 1960s when electron microscopy demonstrated the presence of a carbohydrate-rich, negatively charged outer coat that was called the "glycocalyx." Progressively, electrophoretic procedures were developed that identified the major membrane glycoproteins (GP) t...
متن کاملMembrane type-1 matrix metalloproteinase stimulates tumour cell-induced platelet aggregation: role of receptor glycoproteins.
1. Matrix metalloproteinase-2 (MMP-2) plays a role in agonist- and tumour cell-induced platelet aggregation (TCIPA). 2. MMP-2 is synthesized as a proenzyme and is activated at the cell surface by membrane type-1 matrix metalloproteinase (MT1-MMP, MMP-14). 3. The significance of tumour cell-associated MT1-MMP for TCIPA was investigated using human breast carcinoma MCF7 cells stably coexpressing ...
