Abstract

Obesity, insulin resistance and the metabolic syndrome are associated with changes to the gut microbiota; however, the mechanism by which modifications to the gut microbiota might lead to these conditions is unknown. Here we show that increased production of acetate by an altered gut microbiota in rodents leads to activation of the parasympathetic nervous system, which, in turn, promotes increased glucose-stimulated insulin secretion, increased ghrelin secretion, hyperphagia, obesity and related sequelae. Together, these findings identify increased acetate production resulting from a nutrient-gut microbiota interaction and subsequent parasympathetic activation as possible therapeutic targets for obesity.

  • Acetate is present in cerebrospinal fluid, and gut microbial-derived acetate reaches the brain and triggers PNS signaling.

    “Specifically, acetate has been reported to be present in the cerebrospinal fluid, and gut microbial-derived acetate has been shown to reach the brain and trigger PNS signaling (Nagashima et al., 2010;Perry et al., 2016).”

    From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Perry et al., 2016

  • The gut microbiome and its metabolites modulate ghrelin secretion and CNS functions.

    “The gut microbiome, along with its metabolites, has been reported to modulate ghrelin secretion and CNS functions.”
  • Free short-chain fatty acid levels are virtually undetectable in plasma recovered from germ-free animals.

    “The idea that circulating SCFAs are produced in large part by gut commensals is supported by studies showing that free SCFA levels are virtually undetectable in plasma recovered from germ-free animals51.”

    From Gut microbiota and cardiovascular disease. (2020) · cites this paper as [51]

  • Germ-free mice have lower levels of plasma ghrelin under basal conditions than conventional mice.

    “Indeed, germ-free mice have lower levels of plasma ghrelin under basal conditions than conventional mice [128,129].”
  • Increased acetate production by gut bacteria promotes insulin secretion, hyperphagia, and obesity.

    “increased acetate production by gut bacteria has been found recently to promote insulin secretion, hyperphagia, and obesity [22]”

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.
