Abstract

γδ T cells are unconventional T cells that group into different subsets based on the usage of variable γδ T cell receptor (TCR) gene segments, body location, and functionality. γδ T cells that secrete the proinflammatory cytokine interleukin 17 (IL-17) predominantly express a Vγ4+ or Vγ6+ γδ TCR. The biology and the importance of the γδ TCR of IL-17-producing γδ T cells are not well understood. Here, we investigated the IL-17 production capability of γδ T cells in mice deficient for Vγ4+ and Vγ6+ γδ TCRs using flow cytometry, TCR-seq, and single-cell transcriptomics. Our data show that Vγ1 T cells only partially compensate for the loss of IL-17+ Vγ4 and Vγ6 T cell subsets in lymphoid and nonlymphoid tissues. They develop pre- and postnatally and were predominantly detectable in their physiological body habitats. Collectively, the data underscore the nonredundant roles of Vγ4⁺ and Vγ6⁺ subsets in IL-17-mediated immunity.

在没有Vγ4和Vγ6 T细胞的情况下,Vγ1 T细胞对IL-17产生的部分补偿。
γδ T细胞是一种非常规的T细胞,根据可变γδ T细胞受体(TCR)基因片段的使用、身体位置和功能分成不同的亚群。分泌促炎细胞因子白细胞介素17 (IL-17)的γδ T细胞主要表达Vγ4+或Vγ6+ γδ TCR。产生il -17的γδ T细胞的生物学和γδ TCR的重要性尚不清楚。在这里,我们使用流式细胞术、TCR-seq和单细胞转录组学研究了v - γ4+和v - γ6+ γδ tcr缺失小鼠的γδ T细胞产生IL-17的能力。我们的数据表明,在淋巴组织和非淋巴组织中,Vγ1 T细胞仅部分补偿IL-17+ Vγ4和Vγ6 T细胞亚群的损失。它们在出生前和出生后发育,主要在它们的生理身体栖息地中被检测到。总的来说,这些数据强调了Vγ4 +和Vγ6 +亚群在il -17介导的免疫中的非冗余作用。

期刊介绍: The European Journal of Immunology (EJI) is an official journal of EFIS. Established in 1971, EJI continues to serve the needs of the global immunology community covering basic, translational and clinical research, ranging from adaptive and innate immunity through to vaccines and immunotherapy, cancer, autoimmunity, allergy and more. Mechanistic insights and thought-provoking immunological findings are of interest, as are studies using the latest omics technologies. We offer fast track review for competitive situations, including recently scooped papers, format free submission, transparent and fair peer review and more as detailed in our policies.
