Gene expression analysis in naïve and vaccine (peptide vs. DC) primed pmel-1 CD8 Tcells

Project description:We have shown that DC vaccine is superior to peptide vaccine in terms of priming and expansion of antigen-specific CD8+ T cells. DC vaccine-primed pmel-1 cells displayed better effecter functions than cells by peptide-primed cells in terms of cytokine production and externalization of cytotoxic granules. Furthermore DC vaccine-primed cells were metabolically distinct from peptide-primed cells. To confirm these findings, we performed a microarray analysis using splenic pmel-1 T cells from mice immunized with hgp100 peptide vaccine or DC vaccine. We also used splenic naïve pmel-1 T cells as a control.

Transcriptional effects of IL-6 on peptide-stimulated OT-I CD8 T cells after 2 or 7 days

Project description:Interleukin 6 (IL-6) is a pleiotropic cytokine with diverse roles in homeostasis, inflammation, and cancer. To identify transcriptional patterns and differentiation states induced by IL-6 in CD8 T cells, we performed RNAseq profiling of murine OT-I CD8+ T cells stimulated with SIINFEKL peptide in the presence of exogenous IL-6 (10 ng/ml) or anti-IL6R antibody (to block endogenous IL-6 signaling). Bulk OT-I splenocytes were stimulated with SIINFEKL peptide and CD8 T cells were FACS-sorted for RNA extraction after 2 and 7 days. We found that IL-6 potently repressed classical effector differentiation and promoted a gene expression pattern similar to that of memory precursor cells.

Binding of STAT5 upon IL-2 treatment to genomic sites in mouse CD8 T cells costimulated in vivo through CD134 plus CD137

Project description:OT-I CD8 T cells primed with cognate SIINFEKL peptide and agonists to the costimulatory receptors CD134 and CD137 were stimulated with and without IL-2, and then STAT5 ChIP-seq was performed.

Expression data from OT-I CD8 T cells activated with DC in the presence or absence of CpG-Induced Inflammation

Project description:Inflammatory cytokines promote the accumulation of activated CD8 T cells. Here, we transfer 600 OT-I CD8 T cells iv into naïve C57BL/6 hosts. One day later, 500,000 LPS-matured and OVA257 peptide-coated DC were injected iv into OT-I CD8 T cell seeded hosts with (DC+CpG) or without (DC). Other seeded mice were infected with 2x10^4 virulent Listeria monocytogenes (vLM-OVA) iv. OT-I CD8 T cells were harvested from the spleen, flow sort purified, then RNA was extracted using RNeasy (Qiagen) kit. Naive OT-I CD8 T cells (Naive) were purified from the spleens of OT-I transgenic mice. Each group had three independent biological replicates.Transcriptomes were compared using DAVID analysis (with genes scoring FDR<0.01) and GSEA analysis.

Expression data from OT-I CD8 T cells activated with DC in the presence or absence of CpG-Induced Inflammation

Project description:Inflammatory cytokines promote the accumulation of activated CD8 T cells. Here, we transfer 600 OT-I CD8 T cells iv into naÃ¯ve C57BL/6 hosts. One day later, 500,000 LPS-matured and OVA257 peptide-coated DC were injected iv into OT-I CD8 T cell seeded hosts with (DC+CpG) or without (DC). Other seeded mice were infected with 2x10^4 virulent Listeria monocytogenes (vLM-OVA) iv. OT-I CD8 T cells were harvested from the spleen, flow sort purified, then RNA was extracted using RNeasy (Qiagen) kit. Naive OT-I CD8 T cells (Naive) were purified from the spleens of OT-I transgenic mice. Each group had three independent biological replicates.Transcriptomes were compared using DAVID analysis (with genes scoring FDR<0.01) and GSEA analysis. 3 biological replicates per group. Groups included NaÃ¯ve OT-I CD8 T cells, DC+CpG OT-I CD8 T cells, DC OT-I CD8 T cells, and vLM-OVA OT-I CD8 T cells. Most comparisons used NaÃ¯ve OT-I CD8 T cells as a baseline comparison

Single-cell RNA sequencing of OT-I CD8+ T cells after stimulation with different affinity ligands

Project description:Activation of CD8+ T cells depends exquisitely on the affinity of the T cell receptor (TCR) for a peptide MHC (pMHC) ligand complex. Here, we activated OT-I transgenic CD8+ T cells with pure peptide and examined early activation responses by single-cell RNA-sequencing. T cells were activated with the high affinity OT-I cognate peptide (N4=SIINFEKL) for 1, 3 or 6 hours, or with reduced affinity peptides (T4=SIITFEKL and G4=SIIGFEKL) or the non-binding peptide (NP68=ASNENMDAM) for 6 hours. Cells were then sorted into 96-well plates by FACS and RNA was sequenced following an adapted Smart-Seq2 protocol.

Redirection of therapeutic T cells to a bone marrow niche improves their persistence and anti-tumor functions: transcription profiling by array of resting memory OT-I T_CXCR4) or OT-I T_Control cells isolated from the spleen 90 days following DC vaccination.

Project description:This study reports the improvement in function and antitumor efficacy of CXCR4 overexpression in therapeutic CD8+ T cells. Polyclonal CD8+ T cells from OT-I C57BL/6 (B6) mice were transduced with a modified pMP71 retroviral vector containing murine Cxcr4 and Gfp reporter sequences (T_CXCR4) or with a control vector containing Gfp alone (T_Control), and co-transferred into to B6 mice that were then vaccinated with peptide-pulsed DC. 90 days following DC vaccination, lymphocytes were isolated from the spleen and resting memory OT-I T_CXCR4 and OT-I T_Control cells were FACS sorted to perform gene expression profiling.
