Adhesive functions of platelets lacking glycoprotein IV (CD36).
Glycoprotein IV (GPIV; CD36 or GPIIIb) is a cell surface glycoprotein that has been proposed as mediating a number of physiologically important processes such as the adhesion of platelets to thrombospondin (TSP) and collagen, the cytoadherence of Plasmodium falciparum-infected erythrocytes, and the TSP-dependent interaction of monocytes with platelets and macrophages. Because platelets of the N...

Background: Major platelet adhesive receptors that contribute significantly to thrombus formation include platelet receptor glycoprotein Ibα (GPIbα) of the GPIb-IX-V complex and platelet glycoprotein VI (GPVI). GPIbα plays a crucial role in platelet tethering to sub-endothelial matrix, which initiates thrombus formation at arterial shear rates, whereas GPVI is critically involved in platelets f...
متن کاملPlatelets lacking functional CD36 (glycoprotein IV) show reduced adhesion to collagen in flowing whole blood.
A parallel-plate perfusion chamber has been used to evaluate the contribution of the adhesive membrane glycoprotein CD36 (GPIV) to platelet adhesion on type I collagen in flowing whole blood at a shear rate of 800 s-1. In one series of experiments, reconstituted normal blood (hematocrit 0.4; platelet count 1.5 x 10(5)/microL) was prepared from washed red blood cells, plasma, and washed platelet...
متن کاملGlycoprotein IV mediates thrombospondin-dependent platelet-monocyte and platelet-U937 cell adhesion.
An adhesive interaction between activated platelets and mononuclear phagocytes may contribute to the role these cells play in regulating inflammation, thrombosis, and atherosclerosis. We have previously shown that this adhesive interaction is mediated by the expression of the glycoprotein thrombospondin (TSP) on the surface of activated platelets. We now show that TSP-dependent platelet-monocyt...
متن کاملThe Effect of Gnidilatimonoein from Daphne mucronata, on the Adhesive Property of Human Platelets
The adhesive interaction between tumor cells and the host cells or the extracellular matrix plays a crucial role in tumor metastasis. To evaluate the mediation of cell adhesion by Daphne mucronata, an anti-cancer medicinal plant in Iranian folk medicine, the adhesion of thrombin activated human platelets to the cultured monocytes or HL-60 cells was investigated under the effect of the plant ext...
