Cell surface thiol isomerases may explain the platelet-selective action of S-nitrosoglutathione
S-nitrosoglutathione (GSNO) at low concentration inhibits platelet aggregation without causing vasodilation, suggesting platelet-selective nitric oxide delivery. The mechanism of this selectivity is unknown, but may involve cell surface thiol isomerases, in particular protein disulphide isomerase (csPDI) (EC 5.3.4.1). We have now compared csPDI expression and activity on platelets, endothelial ...
متن کاملPlatelet cell-surface protein disulphide-isomerase mediated S-nitrosoglutathione consumption.
S-nitrosothiols (RSNOs) regulate several aspects of platelet physiology including inhibition of activation, adhesion and aggregation. PDI (protein disulphide-isomerase) has recently been found to be localized to the cell surface, where it exhibits both disulphide-exchange and denitrosation activities. The disulphide-exchange activity of PDI has been linked to aspects of platelet aggregation. Th...
متن کاملIntracellular Trafficking, Localization, and Mobilization of Platelet-Borne Thiol Isomerases.
OBJECTIVE Thiol isomerases facilitate protein folding in the endoplasmic reticulum, and several of these enzymes, including protein disulfide isomerase and ERp57, are mobilized to the surface of activated platelets, where they influence platelet aggregation, blood coagulation, and thrombus formation. In this study, we examined the synthesis and trafficking of thiol isomerases in megakaryocytes,...

متن کاملThiol isomerases in thrombus formation.
Protein disulfide isomerase (PDI), ERp5, and ERp57, among perhaps other thiol isomerases, are important for the initiation of thrombus formation. Using the laser injury thrombosis model in mice to induce in vivo arterial thrombus formation, it was shown that thrombus formation is associated with PDI secretion by platelets, that inhibition of PDI blocked platelet thrombus formation and fibrin ge...
