Abstract

The effector T-cell lineage shows great plasticity. Th17 cells are acknowledged to be instrumental in the response against microbial infection, but are also associated with autoimmune inflammatory processes. Here, we report that human regulatory T cells (CD4posCD25highFoxp3posCD127negCD27pos) can differentiate into IL-17–producing cells, when stimulated by allogeneic antigen-presenting cells, especially monocytes, in the presence of rhIL-2/rhIL-15. These regulatory T cell (Treg)–derived IL-17–producing cells showed high expression of the Th17-related transcription factor RORγt and were positively identified by CCR6 expression. This differentiation process was enhanced by exogenous IL-1β, IL-23, and IL-21, whereas IL-6 or TGFβ did not affect the emergence of IL-17–producing cells. The addition of IL-1 receptor antagonist (IL-1Ra), but not anti–IL-23 antibody, reduced IL-17–producing cell numbers. When an histone deacetylase (HDAC) inhibitor trichostatin A (TSA) was evaluated, we found a profound negative effect on the emergence of IL-17–producing cells from Tregs, implying that Treg differentiation into IL-17–producing cells depends on histone/protein deacetylase activity. Thus, the data suggest that epigenetic modification underlies the phenomenon of Treg plasticity here described.

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.
