The platelet glycoprotein thrombospondin binds specifically to sulfated glycolipids.
The human platelet glycoprotein thrombospondin (TSP) binds specifically and with high affinity to sulfatides (galactosylceramide-I3-sulfate). Binding of 125I-TSP to lipids from sheep and human erythrocytes and human platelets resolved on thin layer chromatograms indicates that sulfatides are the only lipids in the membrane which bind TSP. Binding to less than 2 ng of sulfatide could be detected...
متن کاملCorrelates of plasma and platelet tissue factor pathway inhibitor, factor V, and Protein S
Background Plasma Tissue Factor Pathway Inhibitor (TFPI) circulates bound to factor V (fV) and Protein S (PS). Estrogen therapy decreases plasma TFPI and PS. TFPI, fV, and PS circulate within platelets, and are released upon activation to modulate thrombus formation. Objective Identify factors affecting the concentrations of plasma and platelet TFPI, fV, and PS. Methods Blood samples were o...
متن کاملInteraction of platelet-derived growth factor with thrombospondin 1.
Key factors that mediate vascular smooth muscle cell proliferation and migration are platelet-derived growth factor (PDGF) and thrombospondin 1 (TSP1). We now report that PDGFBB bound tightly and specifically to TSP1, that this interaction was markedly dependent on the disulphide bond arrangement in TSP1, and that binding of PDGFBB to TSP1 did not preclude PDGFBB from binding to its receptor on...
متن کاملLipoprotein (a) binds and inactivates tissue factor pathway inhibitor: a novel link between lipoproteins and thrombosis.
Lipoprotein (a) [Lp(a)] has been associated with both anti-fibrinolytic and atherogenic effects. However, no direct link currently exists between this atherogenic lipoprotein and intravascular coagulation. The current study examined the binding and functional effects of Lp(a), its lipoprotein constituents, apoliprotein (a) [apo(a)] and low-density lipoprotein (LDL), and lysine-plasminogen (L-PL...
متن کاملModulation of tissue factor and tissue factor pathway inhibitor-1 by neutrophil proteases.
During systemic inflammation, neutrophil activation is accompanied by endothelial cell damage and hypercoagulability. Activated neutrophils release serine proteases that participate in tissue injury. We sought to investigate the effects of neutrophil proteases on proinflammatory and procoagulant changes in endothelial cells. The effects of elastase (HNE), cathepsin G (CG), and proteinase 3 (PR3...
