在一项新的研究中，来自加州大学旧金山分校、北京大学、南澳大利亚健康与医学研究所和阿德莱德大学的研究人员发现某些称为肠嗜铬细胞（enterochromaffin, EC）的肠道细胞通过检测有害刺激并释放大量影响神经与大脑沟通的神经递质，在疼痛中发挥着比以前认为的更重要的作用。由此产生的疼痛信号在初始触发后可能会持续很长时间，这可能会导致 肠易激综合征 ...

Circulating serotonin is produced in the duodenum by enterochromaffin cells, specialized endocrine cells in the epithelia lining the gut, and functions within a specialized neuroendocrine network.

Enterochromaffin (EC) cells and expression of leptin, PAX4 (critical factor for EC specification), tryptophane hydroxylase-1 (TPH1, the peripheral rate-limiting enzyme for 5HT) and 5HT were ...
