Abstract

Repair of tissue damaged during inflammatory processes is key to the return of local homeostasis and restoration of epithelial integrity. Here we describe CD161+ regulatory T (T reg) cells as a distinct, highly suppressive population of T reg cells that mediate wound healing. These T reg cells were enriched in intestinal lamina propria, particularly in Crohn's disease. CD161+ T reg cells had an all-trans retinoic acid (ATRA)-regulated gene signature, and CD161 expression on T reg cells was induced by ATRA, which directly regulated the CD161 gene. CD161 was co-stimulatory, and ligation with the T cell antigen receptor induced cytokines that accelerated the wound healing of intestinal epithelial cells. We identified a transcription-factor network, including BACH2, RORγt, FOSL2, AP-1 and RUNX1, that controlled expression of the wound-healing program, and found a CD161+ T reg cell signature in Crohn's disease mucosa associated with reduced inflammation. These findings identify CD161+ T reg cells as a population involved in controlling the balance between inflammation and epithelial barrier healing in the gut.

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.
