Abstract

Metabolism has been shown to integrate with epigenetics and transcription to modulate cell fate and function. Beyond meeting the bioenergetic and biosynthetic demands of T-cell differentiation, whether metabolism might control T-cell fate by an epigenetic mechanism is unclear. Here, through the discovery and mechanistic characterization of a small molecule, (aminooxy)acetic acid, that reprograms the differentiation of T helper 17 (T H 17) cells towards induced regulatory T (iT reg) cells, we show that increased transamination, mainly catalysed by GOT1, leads to increased levels of 2-hydroxyglutarate in differentiating T H 17 cells. The accumulation of 2-hydroxyglutarate resulted in hypermethylation of the Foxp3 gene locus and inhibited Foxp3 transcription, which is essential for fate determination towards T H 17 cells. Inhibition of the conversion of glutamate to α-ketoglutaric acid prevented the production of 2-hydroxyglutarate, reduced methylation of the Foxp3 gene locus, and increased Foxp3 expression. This consequently blocked the differentiation of T H 17 cells by antagonizing the function of transcription factor RORγt and promoted polarization into iT reg cells. Selective inhibition of GOT1 with (aminooxy)acetic acid ameliorated experimental autoimmune encephalomyelitis in a therapeutic mouse model by regulating the balance between T H 17 and iT reg cells. Targeting a glutamate-dependent metabolic pathway thus represents a new strategy for developing therapeutic agents against T H 17-mediated autoimmune diseases.

  • D-2-HG produced by mIDH1 in low grade glioma activates mTOR signaling.

    “D-2-HG produced by mIDH1 in low grade glioma was found to activate mechanistic target of rapamycin (mTOR) signaling133.”
  • D-2-HG destabilises DEPTOR, a negative regulator of mTORC1/2, partly through inhibition of histone demethylase KDM4A.

    “Mechanistically, it was proposed that D-2-HG destabilised DEPTOR, a negative regulator of mTORC1/2 partly through inhibition of the histone demethylase KDM4A133.”

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.
