Optimized CD8 effector TL

Transcriptome analyses of naive, effector and memory CD8 TCRP1A lymphocytes expressing or not an active form of the transcription factor Stat5. TCRP1A CD8 T lymphocytes were activated by their cognate Ag for 72h to induce their differentiation in effector T cells (TCRP1A eTL 72h: 4 replicates S1, S2, S3, S4). In some samples, an active form of Stat5 was introduced (TCRP1A Stat5ca eTL 72h: 2 replicates S9, S10). These 72h activated T cells were either purified and analyzed directly (samples mentioned above) or injected in congeneic hosts and recovered more than 20 days later from the host spleen and lymph nodes: TCRP1A eTL >d20: 2 replicates– S30, S32; TCRP1A Stat5ca eTL >d20: 4 replicates S11, S12, S13, S14). Naive TCRP1A CD8 T lymphocytes (TCRP1A-naive: 4 replicates S33, S34, S35, S36) are included as controls. TCRP1A CD8 T lymphocytes were activated by anti-CD3/CD28. After 24h, an active form of Stat5 was introduced in activated cells. Culture was continued for another 48h to induce their differentiation in effector T cells. These 72h activated T cells were either directly injected in congeneic hosts and recovered more than 14 days later from the host spleen and lymph nodes: T-BetKO Stat5ca >d14: 3 replicates S39, S40, S41.
