Project description:Brd4 deficient and WT GP33-tetramer+ cells were sorted from spleens on D8 of LCMV infection. Tamoxifen was administered on days 5-7 of infection to induce to deletion of Brd4. KLRG1hiCD127lo TE, KLRG1loCD127lo EEC, and KLRG1loCD127hi MP cells were sorted for RNAseq analysis.
Project description:CD4 and CD8 T cells display functional defects during chronic infection such as loss of certain cytokines. Recent studies have suggested that CD4 T cells may actually gain other functions, however. Here, we analyzed gene expression profiles from LCMV-specific CD4 and CD8 T cells throughout the response to either acute LCMV or chronic LCMV infection. This alllowed us to identify CD4-specific changes during chronic infection compared to acute infection but also revealed shared core regulators between CD4 and CD8 T cells. LCMV-specific CD4 and CD8 T cells were isolated 6, 8, 15 and 30 days post infection with LCMV Armstrong or LCMV clone 13. Naïve CD4 and CD8 T cells were also isolated from naïve mice as comparisons. Four replicates of each sample were hybridized. The only exception is LCMV-specific CD4 T cells isolated 6 days post infection with LCMV-Arm where only three replicates were hybridized.
Project description:To identify the subsets of exhausted T cells and to analyze the transcriptional-metabolic programs alongside their developmental trajectories at single-cell resolution, we isolated CD44+ PD-1hi CD8+ T cells from chronically infected wild-type (WT) mice 21 days after infection with the ‘clone 13’ strain of lymphocytic choriomeningitis virus (LCMV) by FACs sorting aand performed scRNA-sequencing.
