Abstract

Dermal IL-17-producing γδT cells have a critical role in skin inflammation. However, their development and peripheral regulation have not been fully elucidated. Here we demonstrate that dermal γδT cells develop from the embryonic thymus and undergo homeostatic proliferation after birth with diversified TCR repertoire. Vγ6T cells are bona fide resident, but precursors of dermal Vγ4T cells may require extrathymic environment for imprinting skin-homing properties. Thymic Vγ6T cells are more competitive than Vγ4 for dermal γδT cell reconstitution and TCRδ(-/-) mice reconstituted with Vγ6 develop psoriasis-like inflammation after IMQ-application. Although both IL-23 and IL-1β promote Vγ4 and Vγ6 proliferation, Vγ4 are the main source of IL-17 production that requires IL-1 signalling. Mice with deficiency of IL-1RI signalling have significantly decreased skin inflammation. These studies reveal a differential developmental requirement and peripheral regulation for dermal Vγ6 and Vγ4 γδT cells, implying a new mechanism that may be involved in skin inflammation.

  • Homozygous CCR10-KO/EGFP-KI mice have dysregulated skin-resident T cells compared to heterozygous mice, characterized mostly by reduction of CD8+ and CD4+ αβT cells but not IL-17A+ αβT or γδT cells.

    “Homozygous CCR10-KO/EGFP-KI (CCR10EGFP/EGFP, or CCR10−/− for simplicity) mice have dysregulated skin-resident T cells compared to heterozygous CCR10-KO/EGFP-KI (CCR10+/EGFP or CCR10+/−) mice, characterized mostly by the reduction of CD8+ and CD4+ αβT cells but not IL-17A+ αβT or γδT cells.20,22,23”

    The Results section, ‘Thymic Vγ4 requires extrathymic environment for skin homing’ (page unavailable), reports that CCR10 deficiency did not reduce dermal Vγ4 cells relative to wild-type mice and that total dermal γδT-cell frequency was unchanged. The paper does not report the claimed reductions in CD8+ and CD4+ αβT cells or compare homozygous CCR10-KO/EGFP-KI mice with heterozygous mice. (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.
