Résumé : Pretreatment of bovine aortic smooth muscle cells in culture with pertussis toxin (PT) or cholera toxin (CT) potentiated the synthesis of prostacyclin (PGI2) induced by 5-hydroxytryptamine (5-HT) and phorbol-12-myristate, 13-acetate (PMA). The production of PGI2 by explants from the bovine aortic media was also synergistically stimulated by 5-HT and CT, whereas PT was inactive. These data are consistent with the hypothesis that guanosine 5'-triphosphate binding proteins are directly involved in the control of phospholipases which release free arachidonic acid for prostaglandin synthesis.
