Abstract

A Western lifestyle with high salt consumption can lead to hypertension and cardiovascular disease. High salt may additionally drive autoimmunity by inducing T helper 17 (T H 17) cells, which can also contribute to hypertension. Induction of T H 17 cells depends on gut microbiota; however, the effect of salt on the gut microbiome is unknown. Here we show that high salt intake affects the gut microbiome in mice, particularly by depleting Lactobacillus murinus. Consequently, treatment of mice with L. murinus prevented salt-induced aggravation of actively induced experimental autoimmune encephalomyelitis and salt-sensitive hypertension by modulating T H 17 cells. In line with these findings, a moderate high-salt challenge in a pilot study in humans reduced intestinal survival of Lactobacillus spp., increased T H 17 cells and increased blood pressure. Our results connect high salt intake to the gut-immune axis and highlight the gut microbiome as a potential therapeutic target to counteract salt-sensitive conditions.

  • Diet has a critical role on gut microbiota function.

    “This further illustrates the critical role diet has on gut microbiota function (Wilck et al., 2017)”

  • Unhealthy dietary interventions, such as high-fat, high-sugar, and high-salt interventions, negatively impact the gut microbiome and induce intestinal inflammation by impairing TH17 cell functions.

    “Unhealthy dietary interventions, such as high-fat, high-sugar, and high-salt interventions, have been shown to negatively impact the gut microbiome and induce intestinal inflammation by impairing TH17 cell functions.698–700”
  • The hypertensive effects of high-salt diets in experimental animals and humans are mediated by reduced levels of Lactobacillus and subsequent increases in proinflammatory T helper 17 cells.

    “Recent data suggest that the hypertensive effects of high-salt diets in experimental animals and humans are mediated by reduced levels of Lactobacillus and subsequent increases in proinflammatory T helper 17 cells (54).”
  • In mice, high salt intake altered the gut microbiota, and treatment with Lactobacillus murinus attenuated salt-induced increases in blood pressure by approximately 5 mmHg.

    “In mice, high salt intake altered the GM, and treatment with Lactobacillus murinus attenuated salt-induced increases in BP by ~5 mmHg 104.”
  • A pilot study in normotensive healthy humans reported that a high-salt diet for 14 days reduced intestinal survival of Lactobacillus and increased blood pressure, although a cause-and-effect relationship between altered gut microbiota and blood pressure was not established.

    “A pilot study in normotensive, healthy humans reported that a high-salt diet for 14 days reduced intestinal survival of Lactobacillus and increased BP, although a cause-and-effect relationship between altered GM and BP was not established104.”

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.
