Abstract

Olfactory receptors are G protein-coupled receptors that mediate olfactory chemosensation and serve as chemosensors in other tissues. We find that Olfr78, an olfactory receptor expressed in the kidney, responds to short chain fatty acids (SCFAs). Olfr78 is expressed in the renal juxtaglomerular apparatus, where it mediates renin secretion in response to SCFAs. In addition, both Olfr78 and G protein-coupled receptor 41 (Gpr41), another SCFA receptor, are expressed in smooth muscle cells of small resistance vessels. Propionate, a SCFA shown to induce vasodilation ex vivo, produces an acute hypotensive response in wild-type mice. This effect is differentially modulated by disruption of Olfr78 and Gpr41 expression. SCFAs are end products of fermentation by the gut microbiota and are absorbed into the circulation. Antibiotic treatment reduces the biomass of the gut microbiota and elevates blood pressure in Olfr78 knockout mice. We conclude that SCFAs produced by the gut microbiota modulate blood pressure via Olfr78 and Gpr41.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • OR51E2 is activated by acetate and propionate and has been detected in the brain of rodents, but not humans.

    “The only one activated by acetate and propionate is the GPCR olfactory receptor family 51 subfamily member 2 (OR51E2 for humans, olfactory receptor 78 -Olfr78 for mice) (Pluznick et al., 2013), which has been detected in the brain of rodents, but not humans (Yuan et al., 2001).”

    From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Pluznick et al., 2013

  • Olfr78 and Gpr41 participate in host blood pressure regulation.

    “Early mechanistic studies by Pluznick and colleagues substantiated this idea by demonstrating the G-protein coupled SCFA receptors olfactory receptor 78 (Olfr78) and G-protein receptor 41 (Gpr41) participate in host blood pressure regulation59–61.”

    From Gut microbiota and cardiovascular disease. (2020) · cites this paper as [60]

  • Pluznick et al. demonstrated that microbiota produce SCFA to modulate blood pressure through SCFA interaction with host GPCRs Olfr78 and Gpr41, and antibiotic treatment can alter blood pressure in Olfr78 knockout mice.

    “Pluznick et al. demonstrated that microbiota could produce SCFA to modulate blood pressure through short-chain fatty acid interaction with the host G protein-coupled receptors (GPCRs) Olfr78 and Gpr41; antibiotic treatment can then alter blood pressure in Olfr78 knockout mice83.”

    From Dietary metabolism, the gut microbiome, and heart failure (2019) · cites this paper as [83]

  • Interventions that target the gut microbiota, such as a high-fibre diet, probiotics and antibiotics, have blood-pressure lowering effects in animal models and in patients with hypertension.

    “Finally, studies in animal models and in patients with hypertension have reported that interventions that target the gut microbiota, such as a high-fibre diet, probiotics and antibiotics, have blood-pressure lowering effects87,92–99.”
  • Administration of propionate modulates blood pressure in mice, likely via binding to G protein-coupled receptor 41 and olfactory receptor 78.

    “Administration of propionate has also been reported to modulate blood pressure in mice, likely via binding to the G protein-coupled receptor 41 (GPR41) and olfactory receptor 78 (OLFR78; also known as OR51E2)93,94.”

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.
