Figure Legend Snippet: Estimated copies per cell of PIM1 and PIM2 protein from quantitative proteomics analysis of ( A ) OT1 CD8 T cells stimulated with SIINFEKL peptide for indicated times from published dataset or ( B ) naive ex vivo and 24 hr αCD3/αCD28 (TCR) activated WT CD8 T cells (see ( G, H )) for further details. ( C ) Fragments per kilobase million (FPKM) of Pim1 , Pim2, and Pim3 mRNA from published bulk RNAseq analysis of naive and 24 hr gp33-41 peptide stimulated P14 CD8 T cells. Lymph node cell suspensions from C57BL/6 (WT) and Pim1 KO/ Pim2 KO (Pim dKO) mice were activated for 24 hr with αCD3/αCD28 (both 0.5 µg/mL) and CD4 and CD8 T cell ( D ) FSC-A SSC-A profiles, ( E ) expression of surface activation markers (CD25, CD44, CD71) or CD8 T cell intracellular IFNγ were measured by flow cytometry. ( F ) Lymph node single-cell suspensions from WT and Pim dKO mice were labelled with CellTrace Violet (CTV), activated with αCD3/αCD28 (both 0.5 µg/mL) and CD4 and CD8 T cell CTV proliferation profiles were measured at indicated time points. ( G, H ) Lymph node cell suspensions from WT and Pim dKO mice were stimulated for 24 hr with αCD3/αCD28 (both 0.5 µg/mL) and activated CD4 and CD8 T cells were sorted for analysis by quantitative proteomics. Data was analysed using proteomic ruler method to estimate protein copy number per cell. An interactive version of the proteomics expression data is available for exploration on the Immunological Proteome Resource website: immpres.co.uk ( G ) Total protein content (µg/million cells) (one-way ANOVA), ( H ) Volcano plots of p-value (-log 10 ) versus fold-change (log 2 ) in protein copy number between Pim dKO and WT. Horizontal dotted line represents multi-test correction cut-off of q=0.05, vertical dotted line shows 1.5-fold change. Phosphoribosyl Pyrophosphate synthase 1 like 1 (Prps1l1), was found to be higher in Pim dKO CD8 T cells, but was a low confidence quantification (based on only two unique peptides) with no known function in T cells. Lymph node single-cell suspensions from WT and Pim dKO mice were labelled with CellTrace Violet (CTV) and ( I ) cells were cultured in IL-7 (5 ng/mL) +/- rapamycin (20 nM) and CD8 T cell numbers measured over time or ( J ) cells were activated with αCD3/αCD28 (both 0.5 µg/mL) +/- rapamycin (20 nM) and CD8 T cell mean division number was calculated over time (two-way ANOVA). Symbols in bar charts represent biological replicates, symbols in ( I ) represent the mean. Error bars show mean ± S.D. Flow cytometry dot plots and histograms are representative of ( D, E ) n=3, except for IFNγ staining which is n=2, ( F ) n=5, or show pooled data from ( I ) n=3–4 and ( J ) n=5 biological replicates, with data collected over at least two independent experiments. Quantitative proteomics was performed on biological triplicates. Figure 1—source data 1. Raw values plotted in .

Figure Legend Snippet: ( A ) OT1 lymph node cell suspensions were SIINFEKL peptide activated for 36 hr, washed then cultured with no cytokine, IL-15 (20 ng/mL) or IL-2 (20 ng/mL) for 4 or 24 hr.

Lymph node or spleen cell suspensions were activated for 2 days with TCR stimulus + cytokine, washed, then split daily into fresh media + cytokine. ( C ) WT (Ly5.1) and Pim dKO LN suspensions were mixed at a 50:50 ratio for T cells and cultured as outlined in ( B ) with TCR stimulus αCD3/αCD28 (both 0.5 µg/mL) + cytokine IL-15 (20 ng/mL), and CD8 T cell number was measured daily. ( D ) WT and Pim dKO T cells were expanded with IL-15 in separate cultures as per ( B, C ) and % live cells (PI-ve) were assessed on days 4 and 6 (two-way ANOVA). ( E–J ) WT and Pim dKO CD8 T cells were activated with TCR stimulus αCD3/αCD28 (both 0.5 µg/mL) + cytokine IL-15 (20 ng/mL), expanded with IL-15 as per ( B ), with an additional CD4 T cell magnetic depletion step on day 3 of culture.
