Abstract

On activation, T cells undergo distinct developmental pathways, attaining specialized properties and effector functions. T-helper (T(H)) cells are traditionally thought to differentiate into T(H)1 and T(H)2 cell subsets. T(H)1 cells are necessary to clear intracellular pathogens and T(H)2 cells are important for clearing extracellular organisms. Recently, a subset of interleukin (IL)-17-producing T (T(H)17) cells distinct from T(H)1 or T(H)2 cells has been described and shown to have a crucial role in the induction of autoimmune tissue injury. In contrast, CD4+CD25+Foxp3+ regulatory T (T(reg)) cells inhibit autoimmunity and protect against tissue injury. Transforming growth factor-beta (TGF-beta) is a critical differentiation factor for the generation of T(reg) cells. Here we show, using mice with a reporter introduced into the endogenous Foxp3 locus, that IL-6, an acute phase protein induced during inflammation, completely inhibits the generation of Foxp3+ T(reg) cells induced by TGF-beta. We also demonstrate that IL-23 is not the differentiation factor for the generation of T(H)17 cells. Instead, IL-6 and TGF-beta together induce the differentiation of pathogenic T(H)17 cells from naive T cells. Our data demonstrate a dichotomy in the generation of pathogenic (T(H)17) T cells that induce autoimmunity and regulatory (Foxp3+) T cells that inhibit autoimmune tissue injury.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Th17 differentiation is on the order of 5 days.

    “Immediate early gene transcription is on the order of minutes [25], while Th17 differentiation is on the order of 5 days [26].”
  • There is an absolute requirement for persistent IL-6 signaling to maintain the Th17 genetic program, and thus Th17 cells.

    “Here, we report that in addition to its key role in Th17 cell induction (3, 4), there is an absolute requirement for persistent IL-6 signaling to maintain the Th17 genetic program, and thus Th17 cells.”
  • IL-6 inhibits the TGFβ-induced generation of Treg cells.

    “On the other hand, IL-6 inhibits the TGFβ-induced generation of Treg cells (166).”

  • Produced IL-6 further induces Th17 cell differentiation through STAT3 in the presence of TGFβ, IL-1β and IL-23, which are rich in inflammatory lesions and tumor microenvironments.

    “The produced IL-6 further induces Th17 cell differentiation through STAT3 in the presence of TGFβ, IL-1β and IL-23, all of which are rich in inflammatory lesions and tumor microenvironments (164, 166, 169–171, 174, 175).”

  • Th17 cells are an independent T helper cell subset.

    “Th17 cells were established as an independent T helper cell subset with the discovery of signature cytokines IL-17A, IL-17F, and IL-22, lineage-specific differentiation factors, and dedicated or “master” transcription factors”

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.
