内容記述 | Purpose:The effect of 5-HT2B receptor-selective agonist BW723C86 was investigated on the outflow of 5-hydroxytryptamine(5-HT)from isolated muscle layer-free mucosal preparations of guinea-pig colon. Methods:The mucosal preparations were incubated in vitro and the outflow of 5-HT from these preparations was determined by high-performance liquid chromatography with electrochemical detection. Results:BW723C86(1-10 μM)produced a sustained increase in the outflow of 5-HT from the mucosal preparations. The BW723C86-evoked 5-HT outflow was inhibited by the two different 5-HT2B receptor antagonists, olanzapine(100 nM)and RS127445(100 nM). The neuropeptide Y1 receptor antagonist BIBO3304(300 nM)markedly inhibited the BW723C86-evoked 5-HT outflow. Conclusion:We found that 5-HT2B receptor-triggered 5-HT release from guinea-pig colonic mucosa is mediated by the activation of 5-HT2B receptors located at endocrine cells and that the 5-HT2B receptortriggered 5-HT release is mediated by endogenously released peptide YY, acting via Y1 receptors. Given that both 5-HT and peptide YY are well-known mediators of nausea and vomiting, the 5-HT2B receptors located at endocrine cells may play a role in the generation of nausea and vomiting. |
