Abstract:
:While there is growing appreciation that the microbiome regulates gut-brain signaling, the underlying mechanisms remain elusive. In this issue of Cell Host & Microbe, Bhattarai et al. (2018) identify bacteria-derived tryptamine as a ligand for the gut-epithelium-expressed GPCR 5-HT4 receptor, thereby functioning as a regulator of gastrointestinal motility.
