Abstract

Short-chain fatty acids (SCFAs), which are generated by the bacterial fermentation of dietary fibers, promote expansion of regulatory T cells (Tregs). Potential therapeutic value of SCFAs has been recently highlighted in the experimental models of T cell-mediated autoimmunity and allergic inflammation. These studies suggest that physiological intestinal concentrations of SCFAs within the millimolar range are crucial for dampening inflammation-mediated processes. Here, we describe opposing effects of SCFAs on T cell-mediated immune responses. In accordance with published data, lower butyrate concentrations facilitated differentiation of Tregs in vitro and in vivo under steady-state conditions. In contrast, higher concentrations of butyrate induced expression of the transcription factor T-bet in all investigated T cell subsets resulting in IFN-g-producing Tregs or conventional T cells. This effect was mediated by the inhibition of histone deacetylase (HDAC) activity and was independent of SCFA-receptors FFA2 and FFA3 as well as of Na+-coupled SCFA transporter Slc5a8. Importantly, while butyrate was not able to induce the generation of Tregs in the absence of TGF-b1, the expression of T-bet and IFN-g was triggered upon stimulation of CD4+ T cells with this SCFA alone. Moreover, the treatment of germ-free (GF) mice with butyrate enhanced the expression of T-bet and IFN-g during acute colitis. Our data reveal that, depending on its concentration and immunological milieu, butyrate may exert either beneficial or detrimental effects on the mucosal immune system.

  • SCFAs promote the expansion of Tregs but also seem to improve the function of effector T cells.

    “These were shown to promote the expansion of Tregs, but they also seem to improve the function of effector T cells10–15.”
  • SCFAs are capable of promoting the activity of CD4+ effector T cells, indicating that the influence of microbial metabolites on the immune system may be more complex than previously thought.

    “On the other side, some reports suggest that SCFAs are also capable of promoting the activity of CD4+ effector T cells, indicating that the influence of microbial metabolites on the immune system may be more complex than previously thought13,15.”
  • SCFAs have context-dependent effects, promoting Treg expansion and also improving effector T cell functions.

    “SCFAs have context-dependent functions: they can promote the expansion of Treg cells and also improve effector T cell functions133–136.”
  • Butyrate could exert bidirectional effects, depending on its concentration and immunological milieu.

    “However, Kespohl et al. described that butyrate could exert bidirectional effects, depending on its concentration and immunological milieu [77].”

  • Lower concentration of butyrate facilitated differentiation of Tregs, whereas high concentration without TGF-β could induce expression of the transcription factor T-bet in all investigated T cell subsets and promote IFN-γ production, contributing to polarization towards Th1 cells.

    “In line with previous studies, lower concentration of butyrate facilitated differentiation of Tregs, whereas high concentration without TGF-β could induce expression of the transcription factor T-bet in all investigated T cell subsets and promote IFN-γ production, contributing to polarization towards Th1 cells [77].”

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.
