Abstract

The interplay between effector T cells and regulatory T cells (Treg cells) is crucial for adaptive immunity, but how Treg cells control diverse effector responses is elusive. We found that the phosphatase PTEN links Treg cell stability to repression of type 1 helper T cell (TH1 cell) and follicular helper T cell (TFH cell) responses. Depletion of PTEN in Treg cells resulted in excessive TFH cell and germinal center responses and spontaneous inflammatory disease. These defects were considerably blocked by deletion of interferon-γ, indicating coordinated control of TH1 and TFH responses. Mechanistically, PTEN maintained Treg cell stability and metabolic balance between glycolysis and mitochondrial fitness. Moreover, PTEN deficiency upregulates activity of the metabolic checkpoint kinase complex mTORC2 and the serine-threonine kinase Akt, and loss of this activity restores functioning of PTEN-deficient Treg cells. Our studies establish a PTEN-mTORC2 axis that maintains Treg cell stability and coordinates Treg cell–mediated control of effector responses.

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.
