Cyproheptadine The aim of this study is to find a relationship between serotonin (5-HT) and its metabolite 5-hydroxy indol acetic acid (5-HIAA) in hippocampus, frontal neocortex and platelets.Serotonin and 5-HIAA were measured in cultured neurons and compared with those produced by h uMan platelets. The cortical neuronal 5-HIAA/serotonin ratio was 4.7 and for hippocampal neurons it was 3.2. In h uMan platelets, this ratio was 1.35 suggesting that the highest serotonin metabolism occurs in the frontal neocortex followed by the hippocampus and platelets. In the presence of 0.3 microM ofp-chlorophenylalanine both cultured neurons and platelets exhibited an approximately 50% decrease in serotonin and 5-HIAA concentration suggesting similarities in the metabolic profile in both preparations. In addition, we found that serotonin by itself does not play any role in platelet aggregation but potentiates this phenomenon in the presence of calci uM ionophore A23187. This synergistic interaction between serotonin (2-5 microM) and A23187 (0.5-2 microM) was inhibited by serotonin receptor blockers [methysergide (IC50 = 18 microM) and cyproheptadine (IC50, 20 microM)] and calci uM channel blockers (verapamil and diltiazem, IC50 = 20 and 40 microM, respectively) that indicate both mechanisms are receptor mediated. Similarly, U73122, an inhibitor of phospholipase C (PLC), blocked the synergistic effect of serotonin and ionophore at an IC50 value of 9.2 microM. Wortmannin, a phosphoinositide 3-kinase (PI 3-K) inhibitor, also blocked the response (IC50 = 2.6 microM) by inhibiting respiratory burst. However, neither genistein, a tyrosine-specific protein kinase inhibitor, nor chelerythrine, a protein kinase C (PKC) inhibitor, affected aggregation. Our results are strongly suggestive of a synergistic interaction between serotonin type-2 and Ca-ionophore via a PLC/Ca signalling pathway. [552740] Drug Info
