IL-9 as a mediator of Th17-driven inflammatory disease

Open access

Abstract

We report that like other T cells cultured in the presence of transforming growth factor (TGF) β, Th17 cells also produce interleukin (IL) 9. Th17 cells generated in vitro with IL-6 and TGF-β as well as purified ex vivo Th17 cells both produced IL-9. To determine if IL-9 has functional consequences in Th17-mediated inflammatory disease, we evaluated the role of IL-9 in the development and progression of experimental autoimmune encephalomyelitis, a mouse model of multiple sclerosis. The data show that IL-9 neutralization and IL-9 receptor deficiency attenuates disease, and this correlates with decreases in Th17 cells and IL-6–producing macrophages in the central nervous system, as well as mast cell numbers in the regional lymph nodes. Collectively, these data implicate IL-9 as a Th17-derived cytokine that can contribute to inflammatory disease.

  • Culture with TGF-β1 may increase IL-9 production from multiple cell types.

    “culture with TGF-β1 may increase IL-9 production from multiple cell types26.”

    The Results and Discussion section (‘Th17 cells produce IL-9’; page not provided) reports dose-dependent induction of IL-9 by TGF-β and IL-9 production under TGF-β culture conditions in several T-cell subsets. It does not specify the β1 isoform or establish the effect in cell types beyond T cells. (LLM, conf=0.82)

  • IL-9 has been shown to promote the development of TH17 cells and increase Treg activity.

    “Most recently, IL-9 has been shown to promote the development of TH17 cells, while increasing Treg activity25,26”

    From The transcription factor PU.1 is required for the development of IL-9-producing T cells and allergic inflammation (2010) · cites this paper as [26]

    The Abstract reports that blocking IL-9 or its receptor correlates with fewer Th17 cells in the CNS, supporting a role for IL-9 in Th17-driven disease. But Results and Discussion says initial Th17 priming appeared equivalent to controls, so the paper does not establish that IL-9 promotes Th17 development. It reports that Treg cells produce IL-9 and links IL-9 to immunosuppression, but does not show increased Treg activity. (LLM, conf=0.84)

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.
