Human Platelet Secretion and Aggregation Induced by Calcium Ionophores Inhibition by PGE and Dibutyryl Cyclic AMP

Ca 2+, Mg2+-ionophores X537A and A23,187 (10-r-10 -6 M) induced the release of adenine nucleotides adenosine diphosphate (ADP, adenosine triphosphate (ATP), serotonin, /3-glucuronidase, Ca 2+, and Mg 2+ from washed human platelets. Enzymes present in the cytoplasm or mitochondria, and Zn 2+ were not released. The rate of ATP and Ca 2+ release measured by firefly lantern extract and murexide dye...

Human platelet secretion and aggregation induced by calcium ionophores. Inhibition by PGE1 and dibutyryl cyclic AMP

Ca2+, Mg2+-ionophores X537A and A23,187 (10(-7)-10(-6) M) induced the release of adenine nucleotides adenosine diphosphate (ADP, adenosine triphosphate (ATP), serotonin, beta-glucuronidase, Ca2+, and Mg2+ from washed human platelets. Enzymes present in the cytoplasm or mitochondria, and Zn2+ were not released. The rate of ATP and Ca2+ release measured by firefly lantern extract and murexide dye...

Cordycepin (3'-deoxyadenosine) inhibits human platelet aggregation in a cyclic AMP- and cyclic GMP-dependent manner.

Cordycepin (3'-deoxyadenosine) is isolated from Cordyceps militaris, a species of the fungal genus Cordyceps. Cordycepin is an ingredient used in traditional Chinese medicine and is prescribed for various diseases, such as cancer and chronic inflammation. In this study, we investigated the novel effect of cordycepin (3'-deoxyadenosine) on collagen-induced human platelet aggregation. Cordycepin ...

Inhibition of platelet-activating-factor-induced human platelet activation by prostaglandin D2. Differential sensitivity of platelet transduction processes and functional responses to inhibition by cyclic AMP.

It has been proposed that cyclic AMP inhibits platelet reactivity: by preventing agonist-induced phosphoinositide hydrolysis and the resultant formation of 1,2-diacylglycerol and elevation of cytosolic free Ca2+ concentration [( Ca2+]i); by promoting Ca2+ sequestration and/or extrusion; and by suppressing reactions stimulated by (1,2-diacylglycerol-dependent) protein kinase C and/or Ca2+-calmod...

Decrease of platelet aggregation and spreading via inhibition of the cAMP phosphodiesterase by trapidil.

Trapidil (N,N-diethyl-5-methyl[1,2,4]triazolo[1,5-alpha]pyrimidine-7-amine ) inhibits platelet spreading and aggregation induced by arachidonic acid (AA), a stable analogue of prostaglandin (PG) endoperoxides (U46619), ADP, and low concentrations of thrombin, but not by A23187 and high concentrations of thrombin. Trapidil does not affect platelet adenylate cyclase but inhibits the cAMP PDE by a...
