Issue Date: | 1-Jul-2019 | Date: | 2019-05-29 | Publication information: | The Journal of experimental medicine 2019; 216(7): 1682-1699 | Abstract: | Interleukin (IL)-17-producing CD8+ T (Tc17) cells have emerged as key players in host-microbiota interactions, infection, and cancer. The factors that drive their development, in contrast to interferon (IFN)-γ-producing effector CD8+ T cells, are not clear. Here we demonstrate that the transcription factor TCF-1 (Tcf7) regulates CD8+ T cell fate decisions in double-positive (DP) thymocytes through the sequential suppression of MAF and RORγt, in parallel with TCF-1-driven modulation of chromatin state. Ablation of TCF-1 resulted in enhanced Tc17 cell development and exposed a gene set signature to drive tissue repair and lipid metabolism, which was distinct from other CD8+ T cell subsets. IL-17-producing CD8+ T cells isolated from healthy humans were also distinct from CD8+IL-17- T cells and enriched in pathways driven by MAF and RORγt Overall, our study reveals how TCF-1 exerts central control of T cell differentiation in the thymus by normally repressing Tc17 differentiation and promoting an effector fate outcome. | URI: | https://ahro.austin.org.au/austinjspui/handle/1/20832 | DOI: | 10.1084/jem.20181778 | ORCID: | 0000-0002-9522-9320 0000-0002-9746-2839 0000-0001-6632-7610 0000-0001-8812-2763 0000-0002-3236-9609 0000-0001-6529-5426 0000-0001-7513-6779 0000-0003-1507-0864 0000-0002-8960-6222 0000-0002-7788-8867 0000-0003-1639-4932 0000-0003-1664-6060 0000-0002-8496-6632 0000-0002-3009-5472 0000-0002-9163-7669 0000-0002-4697-7410 0000-0001-6141-335X 0000-0003-1182-7735 0000-0002-9660-9587 |
