Abstract

Interleukin 23 (IL-23) and IL-17 have been linked to the pathogenesis of several chronic inflammatory disorders, including inflammatory bowel disease. Yet as an important function for IL-23 is emerging, the function of IL-17 in inflammatory bowel disease remains unclear. Here we demonstrate IL-17A-mediated protection in the CD45RBhi transfer model of colitis. An accelerated wasting disease elicited by T cells deficient in IL-17A correlated with higher expression of genes encoding T helper type 1-type cytokines in colon tissue. IL-17A also modulated T helper type 1 polarization in vitro. Furthermore, T cells deficient in the IL-17 receptor elicited an accelerated, aggressive wasting disease relative to that elicited by wild-type T cells in recipient mice. Our data demonstrate a protective function for IL-17 and identify T cells as not only the source but also a target of IL-17 in vivo.

  • IL-17A- and IL-22-producing Th17 cells appear to be protective rather than pathogenic in the intestines.

    “Given that IL-17A- and IL-22-producing Th17 cells appear to be protective rather than pathogenic in the intestines (84)”

    From T <sub>H</sub> 17 cells require ongoing classic IL-6 receptor signaling to retain transcriptional and functional identity (2020) · cites this paper as [84]

    The Results ('IL-17A modulates T cell–driven colitis'; page unavailable) show that IL-17A delayed disease onset in a mouse T-cell-transfer model, supporting a protective role in that setting. The paper does not establish that IL-22-producing Th17 cells are protective; the Discussion reports that IL-22 was not responsible for the accelerated disease seen without IL-17A. The claim also extends a model-specific finding to the intestines generally. (LLM, conf=0.88)

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.
