Bidirectional integrin αIIbβ3 signalling regulating platelet adhesion under flow: contribution of protein kinase C
Platelet adhesion on von Willebrand factor (vWf) requires the co-ordinated adhesive function of glycoprotein Ib/V/IX and integrin αIIbβ3. Recent evidence [Nesbitt, Kulkarni, Giuliano, Gonclaves, Dopheide, Yap, Harper, Salem and Jackson (2002) J. Biol. Chem. 277, 2965–2972] suggests that outside-in signals from both receptors play important roles in regulating plateletadhesion dynamics under flo...
متن کاملEndothelial C-reactive protein increases platelet adhesion under flow conditions.
While data regarding the pathogenetic role of C-reactive protein (CRP) in atherothrombosis are accumulating, it is still controversial whether local CRP secretion is of any pathobiological significance. The present study examined whether endothelial-derived CRP modulates autocrine prothrombotic activity. Endothelial cells were isolated from hearts of mice transgenic to human CRP and grown in pr...
متن کاملPhosphoinositide 3-kinases and the regulation of platelet function.
A clear understanding of the role of PI (phosphoinositide) 3-kinases in supporting the haemostatic function of platelets has been slow to evolve. In fact, insight into the roles of individual PI 3-kinase isoforms in platelet function remains rudimentary. However, based on in vitro studies using wortmannin and LY294002, there is evidence for an important role for PI 3-kinases in regulating a bro...
متن کاملIntegrin-mediated platelet adhesion.
Adhesion of platelets to the damaged subendothelium is a prerequisite reaction for the initiation of hemostasis in vivo. Platelet membranes contain high concentrations of integrins and other glycoproteins (GPs) that are involved in the platelet adhesion to the extracellular matrix. In the present review, we focus on two platelet integrins, integrin alphaIIb beta3 (GPIIb/IIIa) and integrin alpha...
متن کاملIntegrin-protein kinase C relationships.
The integrins have an ability to interact with extracellular matrix proteins to confer adhesive and motile properties on cells. The means by which these activities operate and the manner in which they are integrated with cell functions is of particular relevance to many biological processes. In the present paper, the developing understanding of the bi-directional relationship between the protei...
