Platelets and thrombin generation.
This review examines the evidence that platelets play a major role in localizing and controlling the burst of thrombin generation leading to fibrin clot formation. From the first functional description of platelets, it has been recognized that platelets supply factors that support the activation of prothrombin. Studies have demonstrated that on activation, the amount of one specific lipid, phos...
متن کاملThrombin-induced protein phosphorylation in human platelets.
Intact human platelets loaded with 32PO4 contain multiple phosphorylated proteins. Thrombin treatment of intact 32PO4-loaded platelets results in a 2-6-fold increase in phosphorylation of a platelet protein (designated "peak 7" protein) of approximately 40,000 mol wt as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis and by gel filtration on Sephadex G-150. A similar inc...
متن کاملThrombin generation in patients with cirrhosis: the role of platelets.
Coagulation factor defects, thrombocytopenia, and thrombocytopathy are associated with cirrhosis. However, bleeding in patients who have cirrhosis does not entirely correlate with abnormal coagulation tests. Recently, it was shown that because of the concomitant abnormalities of the procoagulant and anticoagulant drives, thrombin generation in plasma patients with cirrhosis is normal when asses...
متن کاملInteraction of platelet plasma membranes with thrombin-activated platelets.
This study described the binding of platelet plasma membranes to either control or thrombin-activated platelets. Glycoproteins in plasma membranes isolated from human platelets were labeled by oxidation with periodate followed by reduction with [3H]NaBH4. Labeled membranes were incubated with either control or thrombin-activated platelets. The amount of membranes bound was measured by separatin...
متن کاملThe binding of human and bovine thrombin to human platelets.
Human thrombin binds to specific receptors on the surface of human platelets in a manner analogous to bovine thrombin. Thus, two classes of binding are observed--high affinity with a dissociation constant (Kdiss) of 0.02 U/ml and low affinity with a Kdiss of 5 U/ml. Bovine and human thrombin bind to the same platelet receptors, although bovine thrombin binds with slightly greater affinity. When...
