Serotonin (5-HT) plays an important role as a signalling molecule in the gastrointestinal (GI) tract. The regulation of GI sensitivity via 5-HT is mediated by specific 5-HT receptor subytypes on intrinsic and extrinsic afferents. This review discusses visceral afferent hypersensitivity in irritable bowel syndrome (IBS) and the importance of 5HT(3), 5HT(4), and 5HT(2B) receptor-mediated mechanisms in the regulation of visceral sensitivity.
血清素（5-羟色胺，5-HT）作为一种信号分子在胃肠道中发挥着重要作用。5-HT对胃肠道敏感性的调节是由内在和外在传入神经上特定的5-HT受体亚型介导的。本文综述了肠易激综合征（IBS）中的内脏传入神经超敏反应以及5HT(3)、5HT(4)和5HT(2B)受体介导的机制在调节内脏敏感性中的重要性。
