<h4>Background & aims</h4>Gastrointestinal (GI) enterochromaffin (EC) cells are specialised sensors of luminal stimuli. They secrete most of the body's serotonin (5-HT), and are critical for modulating GI motility, secretion, and sensation, while also signaling satiety and intestinal discomfort. The aim of this study was to investigate mechanisms underlying the regulation of human EC cells, and the relative importance of direct nutrient stimulation compared with neuronal and paracrine regulation  ...[more]
