The Transcription Factor IRF4 Determines the Anti-Tumor Immunity of CD8+ T cells

Project description:Four TIL populations from B16-F10 melanoma were analyzed by scRNA-seq, including adoptively transterred anti-tumor CD8+ Pmel-1 T cells that were transduced with IRF4 (sample 1, IRF4_Pmel) or GFP control (Sample 3, Ctrl_Pmel), and CD45+ endogenous TILs from either the IRF4 group (Sample 2, IRF4_TILs) or Ctrl group (Sample 4, Ctrl_TILS).

Tumor-induced double positive T cells display distinct lineage commitment mechanisms and functions.

Project description:Transcription factors ThPOK and Runx3 regulate the differentiation of "helper" CD4+ and "cytotoxic" CD8+ T cell lineages respectively, inducing single positive (SP) T cells that enter the periphery with the expression of either the CD4 or CD8 co-receptor. Despite the expectation that these cell fates are mutually exclusive and that mature CD4+CD8+ double positive (DP) T cells are present in healthy individuals and augmented in the context of disease, yet their molecular features and pathophysiologic role are disputed. Here, we show DP T cells in murine and human tumors as a heterogenous population originating from SP T cells which re-express the opposite co-receptor and acquire features of the opposite cell type's phenotype and function following TCR stimulation. We identified distinct clonally expanded DP T cells in human melanoma and lung cancer by scRNA sequencing and demonstrated their tumor reactivity in cytotoxicity assays. Our findings indicate that antigen stimulation induces SP T cells to differentiate into DP T cell subsets gaining in polyfunctional characteristics.

Retinoic acid determines the in vivo fate-commitment of splenic pre-dendritic cells

Project description:Comparison of gene expression changes of FACS sorted splenic CD11b+CD8a- and CD11b-CD8a+ cDC subsets reconstituted in vivo following total body irradiation in combination with exogenous retinoic acid or vehicle control. Mice maintained on a control diet were subjected to 6 Gy total body irradiation and then provided exogenous retinoic acid or vehicle control beginning on D(+)3 after irradiation. All treated mice also received adoptive T cell transfer of either Trp-1 CD4+ or Pmel-1 CD8+ T cells, rVV, and IL-2. Splenic cDCs were isolated on D(+)10 after total body irradiation by FACS sorting.

The role of the transcriptional co-regulator Lmo4 in CD8+ T cell stemness, memory formation and antitumor immunity

Project description:We aimed to evaluate if Lmo4 is directly involved in the generation and preservation of stem cell-like T cells and if adoptively transferred Lmo4-overexpressing pmel-1 CD8+ T cells (which identify the shared melanoma-melanocyte differentiation antigen gp100) are therapeutically effective in mice bearing subcutaneous B16-hgp100 melanomas. Moreover, our purpose was to investigate the mechanisms by which Lmo4 regulates CD8+ T cell differentiation.
