A Microbial Drugstore for Motility
Open accessAbstract
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.

Tryptamine activates the 5-HT4 receptor expressed in the colonic epithelium to control colonic transit.
“Much attention has been directed towards the GI tract, in which tryptamine activates the 5-HT 4 receptor expressed in the colonic epithelium to control colonic transit (Bhattarai et al., 2018;Cryan et al., 2018).”
From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Cryan et al., 2018
The supplied passage has no section or page label and contains only reference links. Searches for tryptamine, epithelial 5-HT4 receptors, and colonic transit returned the same links, so the available copy does not establish whether the paper makes the attributed claim. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
