Abstract

Regulatory T cells (T reg cells) deficient in the transcription factor Foxp3 lack suppressor function and manifest an effector T (T eff) cell-like phenotype. We demonstrate that Foxp3 deficiency dysregulates metabolic checkpoint kinase mammalian target of rapamycin (mTOR) complex 2 (mTORC2) signaling and gives rise to augmented aerobic glycolysis and oxidative phosphorylation. Specific deletion of the mTORC2 adaptor gene Rictor in Foxp3-deficient T reg cells ameliorated disease in a Foxo1 transcription factor-dependent manner. Rictor deficiency re-established a subset of T reg cell genetic circuits and suppressed the T eff cell-like glycolytic and respiratory programs, which contributed to immune dysregulation. Treatment of T reg cells from patients with FOXP3 deficiency with mTOR inhibitors similarly antagonized their T eff cell-like program and restored suppressive function. Thus, regulatory function can be re-established in Foxp3-deficient T reg cells by targeting their metabolic pathways, providing opportunities to restore tolerance in T reg cell disorders.

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.
