Metabolism has been shown to integrate with epigenetics and transcription to modulate cell fate and function. Beyond meeting bioenergetic and biosynthetic demands to support T-cell differentiation, whether metabolism might control T-cell fate through epigenetic mechanism is unclear. Here through discovery and mechanistic characterization of a small molecule, (aminooxy)-acetic acid (AOA), that reprograms TH17 differentiation toward iTreg cells, we show increased transamination mainly via Got1 leads to elevated 2-hydroxyglutarate (2-HG) level in differentiating TH17 cells. Accumulating 2-HG resulted in hypermethylation of FOXP3 gene locus and inhibited FOXP3 transcription, essential for fate determination towards TH17 cells. Inhibiting conversion of glutamate into alpha-ketoglutaric acid (α-KG) inhibits 2-HG production, reduces methylation of FOXP3 gene locus, and increases FOXP3 expression. This consequently blocks TH17 cell differentiation by antagonizing RORγt function and promotes polarization into iTreg cells. Selective inhibition of Got1 with AOA ameliorated mouse EAE disease in a therapeutic model by regulating TH17/iTreg balance. Targeting a glutamate-dependent metabolic pathway thus represents a novel strategy for developing therapeutics against TH17-mediated autoimmune diseases.
