Phenotypic and transcriptional differences of memory CD8 + T cells generated after a viral or a tumoral challenge Naive F5 x CD45.1 cells (2.10 5 ) were i.v. transferred in B6 mice 1-day prior immunization with VV-NP68 (i.n., 2.10 5 pfu) or EL4-NP68 cells (s.c., 2,5.10 6 cells). (A) Viral load was measured in the lung by qPCR, or tumor volume (mm 3 ) was assessed by measuring its length, width, and thickness over time. (B) The number of Vir-CD8 + and Tum-CD8 + cells was determined over time in the blood by flow cytometry. (C and D) The expression of Ki67 (C) and Bcl2 (D) by Vir-CD8 + and Tum-CD8 + cells was measured over time in the blood. (E) The phenotype of Vir-CD8 + and Tum-CD8 + cells was analyzed 31 days after infection in the spleen, and the percentages of cells expressing each marker are represented as a heatmap. The statistical significance of differences was determined using a two-way ANOVA (C–E) (∗ p < 0.05, ∗∗ p < 0.01, and ∗∗∗ p < 0.001). Data are represented as mean ± SD and are representative of 3 independent experiments ( n = 5 to 10 mice per group). (F–I) 60 days after immunization, naive F5 and Vir-CD8 + and Tum-CD8 + cells were single-cell sorted, and stimulated with NP68 peptide (10 nM) for 2 h or left untreated. The transcriptome was analyzed by scRNAseq ( n = 476 cells). (F) Clustering of cells projected on a UMAP colored by populations. (G) Proportion of sorted populations in each cluster.

Tum-CD8 + memory cells display altered cytokine production but not cytotoxic capacities compared to Vir-CD8 + memory cells Naive F5 x CD45.1 cells (2.10 5 ) were i.v. transferred in B6 mice 1-day prior immunization with VV-NP68 (i.n., 2.10 5 pfu) or EL4-NP68 cells (s.c., 2,5.10 6 cells). (A and B) At 30 dpi, F5 memory cells were restimulated with NP68 (10 nM) for 4h in the presence of GolgiStop. The production of IFNγ, TNF, and IL-2 was measured by flow cytometry and expressed in % of total F5 (A) or MFI within the cytokine+ cells (B). (C and D) At 30 dpi, F5 memory cells were restimulated with NP68 (10 nM) for 4h in the presence (cytokines) or absence (CD69) of GolgiStop. The production of IFNγ and TNF and the upregulation of CD69 were measured by flow cytometry over time and expressed in % (C) or MFI (D). (E) The production of IFNγ was measured in supernatant after 4 or 24h of stimulation. (F and G) At 30 dpi, F5 memory cells were restimulated with various doses of NP68 for 4h in the presence of GolgiStop, and the production of IFNγ and TNF was measured by flow cytometry (F). EC 50 was determined (G). (H and I) Splenocytes were incubated with NP68 (10 nM) or control medium for 2h and labeled with CTV or CFSE, respectively. A 1:1 ratio of NP68-loaded splenocytes: control splenocytes (2.10 6 cells) was injected i.v. in Tum-CD8 + or Vir-CD8 + challenged mice at the memory stage. Representative histograms depicting control and CTV-labeled NP68-loaded splenocytes are shown (H). The percentage of NP68-loaded splenocytes killed was evaluated at 6-, 16-, or 44-h post-transfer (I). (J)Total CD8 + enriched from Tum-CD8 + or Vir-CD8 + challenged mice were labeled with CTV and stimulated with NP68-loaded DCs (1:1 ratio) for 4 days in the presence of IL-2.

A transient tumoral challenge is sufficient to alter the protection capacity of F5 memory cells Naive F5 x CD45.1 cells (2.10 5 ) were i.v. transferred in B6 mice 1-day prior immunization with VV-NP68 (i.n., 2.10 5 pfu) or EL4-NP68 cells (s.c., 2,5.10 6 cells). (A–D) At 30 dpi, Vir- or Tum-challenged mice were infected with VV-NP68 (2.10 5 pfu). Six days after infection, mice received an i.v. injection of anti-CD8 antibody, and the proportion of cells within the tissue and the vasculature of the lung was determined (A). The proportion of memory CD8 + T cells in the lung tissue among all memory CD8 + T cells was determined (B). The expression of CD49a (C) and CD49d (D) was measured on memory CD8 + T cells within the lung tissue and vasculature. (E) At 30 dpi, Vir- or Tum-challenged mice were infected with Flu-NP68 (5.10 4 TCID50), and the weight loss was followed for 6 days. (F) At 30 dpi, Vir-CD8 + and Tum-CD8 + memory cells were FACS-sorted and transferred into B6 host (1,2.10 5 cells, i.v. route). One day after transfer, mice received a lethal dose of Flu-NP68 (2.10 6 TCID 50), and survival was followed for 10 days. The statistical significance of differences was determined with 1-way (B) or 2-way (C–E) ANOVA test (∗ p > 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001, and ∗∗∗∗ p < 0.0001), or log rank test (F).

POU2AF1 promotes T-ALL development via transcriptional activation of SLC7A11. ( A ) Western blot analysis of SLC7A11 protein levels in the EL4 cell lines. ( B ) The protein level of SLC7A11 was determined in WT and KO T-ALL cells by Western blotting ( n = 3). ( C ) POU2AF1 and SLC7A11 levels were measured in bone marrow cells from transplanted WT, Bcat1 -KO, Pou2af1 -overexpressing WT or Bcat1 -KO mice by Western blotting. ( D ) Luciferase reporter assay evaluating the transcriptional activation of Slc7a11 by Pou2af1 -WT and Pou2af1 -K5R ( n = 3). ( E ) ChIP assay showing the binding of Pou2af1 -WT and Pou2af1 -K5R to the Slc7a11 promoter region ( n = 3). ( F – G ) Representative flow cytometric analysis of GFP + mCherry + leukemia cells (The markers for the indication of leukemia cells were GFP + and mCherry + , which were the tags for the MSCV- Notch1 -IRES-GFP plasmid and MSCV-mCherry overexpression plasmid) in peripheral blood from recipient mice 3 weeks after transplantation with WT and KO T-ALL cells overexpressing Slc7a11 . ( H – I ) Representative images and quantification of the liver, spleen and thymus morphology in recipient mice ( n = 3). ( J ) Survival analysis of recipient mice ( n = 5). The data are presented as the means ± SDs. One-way ANOVA with Tukey’s multiple comparison test ( G ), log-rank test ( J ) and two-way ANOVA with Sidak’s multiple comparison test ( D , I ) were used for comparisons of statistical significance (*, P < 0.05; **, P < 0.01; and ***, P < 0.001)
