A gut sense for a microbial pattern regulates feeding - Nature A study reveals a gut–brain sensory pathway through which the microbial component flagellin activates neuropod cells in the colon to signal the brain and reduce feeding in mice.

#WeekendRead! #EveryCellIsAnImmuneCell! #TollPower! Kaelberer Bohorquez &co show @nature.com that #TLR5 signaling in response to flagellin drives neuropeptide PYY release by gut colonic neuropod cells, activating vagal neurons that signal to #brain, reducing feeding via a “neurobiotic sense”!
