Production of interleukin 22 but not interleukin 17 by a subset of human skin-homing memory T cells

Abstract

Interleukin 22 (IL-22) is a cytokine produced by the T(H)-17 lineage of helper T cells and NK-22 subset of natural killer cells that acts on epithelial cells and keratinocytes and has been linked to skin homeostasis and inflammation. Here we characterize a population of human skin-homing memory CD4(+) T cells that expressed the chemokine receptors CCR10, CCR6 and CCR4 and produced IL-22 but neither IL-17 nor interferon-gamma (IFN-gamma). Clones isolated from this population produced IL-22 only and had low or undetectable expression of the T(H)-17 and T helper type 1 (T(H)1) transcription factors RORgammat and T-bet. The differentiation of T cells producing only IL-22 was efficiently induced in naive T cells by plasmacytoid dendritic cells in an IL-6- and tumor necrosis factor-dependent way. Our findings delineate a previously unknown subset of human CD4(+) effector T cells dedicated to skin pathophysiology.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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 and Th22 subsets are pivotal to tackle extracellular pathogens, such as extracellular bacteria and fungi, and they both lack CXCR3 and express CCR6 and CCR4.

    “Th17 and Th22 subsets are pivotal to tackle extracellular pathogens, such as extracellular bacteria and fungi, and they both lack CXCR3 and express CCR6 and CCR4 [152-154].”
  • Th17 can be distinguished by expression of killer-cell lectin-like receptor CD161 (KLRB1), while Th22 expresses the skin-homing receptor CCR10.

    “However, Th17 can be distinguished by the expression of the killer-cell lectin-like receptor CD161 (KLRB1) [155,156], while Th22 expresses the skin-homing receptor CCR10 [154].”

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.
