Bile acid modifications at the microbe-host interface: potential for nutraceutical and pharmaceutical interventions in host health

Abstract

Bile acids have emerged as important signaling molecules in the host, as they interact either locally or systemically with specific cellular receptors, in particular the farnesoid X receptor (FXR) and TGR5. These signaling functions influence systemic lipid and cholesterol metabolism, energy metabolism, immune homeostasis, and intestinal electrolyte balance. Through defined enzymatic activities, the gut microbiota can significantly modify the signaling properties of bile acids and therefore can have an impact upon host health. Alterations to the gut microbiota that influence bile acid metabolism are associated with metabolic disease, obesity, diarrhea, inflammatory bowel disease (IBD), Clostridium difficile infection, colorectal cancer, and hepatocellular carcinoma. Here, we examine the regulation of this gut-microbiota-liver axis in the context of bile acid metabolism and indicate how this pathway represents an important target for the development of new nutraceutical (diet and/or probiotics) and targeted pharmaceutical interventions.

  • Expansion of microbial BSH activity has increased the diversity of bile acids in the host.

    “The expansion of microbial BSH activity has increased the diversity of bile acids in the host (Joyce and Gahan, 2016).”

    From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Joyce and Gahan, 2016

    The “Microbial Conversions of Bile Acids” section says BSH produces unconjugated bile acids and enables further microbial modifications; the “Bile Acid Synthesis and Circulation in the Host” section says host and bacterial modifications generate bile-acid diversity. The review also reports that elevated BSH activity can alter bile-acid profiles, but it does not establish that an expansion of BSH activity increased bile-acid diversity in hosts. (LLM, conf=0.82)

  • Microbially derived secondary bile acids are hypothesized to be interkingdom signaling molecules due to their ability to influence the composition and function of the gut microbiota as well as host physiology.

    “Microbially derived secondary bile acids are hypothesized to be interkingdom signaling molecules due to their ability to influence the composition and function of the gut microbiota as well as host physiology (407, 408).”
  • Bile that is not re-absorbed in terminal small intestine undergoes further transformation by the intestinal microbiota.

    “Bile that is not re-absorbed in terminal small intestine undergoes further transformation by the intestinal microbiota (Joyce and Gahan, 2016).”
  • Blautia and Bifidobacterium species are involved in the transformation of host bile.

    “Furthermore, Blautia and Bifidobacterium species are involved in the transformation of host bile.”

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.
