Abstract

Microbial metabolites, such as short-chain fatty acids (SCFAs), are highly produced in the intestine and potentially regulate the immune system. We studied the function of SCFAs in the regulation of T-cell differentiation into effector and regulatory T cells. We report that SCFAs can directly promote T-cell differentiation into T cells producing interleukin-17 (IL-17), interferon-γ, and/or IL-10 depending on cytokine milieu. This effect of SCFAs on T cells is independent of GPR41 or GPR43, but dependent on direct histone deacetylase (HDAC) inhibitor activity. Inhibition of HDACs in T cells by SCFAs increased the acetylation of p70 S6 kinase and phosphorylation rS6, regulating the mTOR pathway required for generation of Th17 (T helper type 17), Th1, and IL-10(+) T cells. Acetate (C2) administration enhanced the induction of Th1 and Th17 cells during Citrobacter rodentium infection, but decreased anti-CD3-induced inflammation in an IL-10-dependent manner. Our results indicate that SCFAs promote T-cell differentiation into both effector and regulatory T cells to promote either immunity or immune tolerance depending on immunological milieu.

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.
