RNAseq analysis of PS+ vs. PS- effector CD8 T cells sorted from spleen of LCMV-Armstrong infected mice

Project description:We report the transcriptional profile of phosphatidylserine (PS) positive and PS negative CD44+CD62L- effector CD8+ T cells from LCMV-Armstrong infected mice sorted from spleens on day5 amd day10 after infection. PS was stained in vivo by injection of MFG-E8-eGFP. PS+ cells acquire PS through binding of extracellular vesicles (EVs). Binding of EVs by effector CD8+ T cells is strongly enhanced during LCMV infection and peaks between day5 and day10 post infection. Effector T cell gene signature is increased in EV+ CD8+ T cells compared to their EV- counterparts.

Gene expression profile analysis of mouse whole spleen following infection by lymphocytic choriomeningitis virus (LCMV), comparing LCMV-Armstrong and LCMV-Clone 13 expression patterns at 0, 5, 9, and 30 days

Project description:To identify mechanisms behind immunosuppression during virus infections, we infected mice with LCMV-Armstrong and LCMV-Clone 13 expression patterns. LCMV-Armstrong induces a T-cell reaction that resolves infection within 8-10 days, while LCMV-Clone13 generates a persisten infection through immunosuppression. We used microarray to uncover splenic gene expression patterns specific to each LCMV infection at 5, 9, and 30 days C57BL6 mice, 6-10 weeks old, were infected with LCMV-Armstrong and LCMV-Clone 13 or left uninfected (naïve). At days 5, 9, and 30 whole spleens were harvested for RNA extraction and hybridization on Affymetric microarray.

mRRBS analysis of C1qbp sufficient and deficient CD8+ T cells sorted from mice post infection with LCMV Armstrong

Project description:This study is aimed to explore whether C1qbp deficiency affects the DNA methylation status during the differentiation stage of CD8+ T cells. Transferred WT and C1qbp KO P14 cells sorted from the spleen of donor mice on day 5 post-infection with LCMV Armstrong were collected. Genomic DNA was isolated for mRRBS. mRRBS analysis provided evidence of DNA methylation changes between WT and C1qbp KO CD8+ T cells. Our study have shown that, on day 5 post-infection with LCMV Armstrong, C1qbp KO CD8+ T cells have increased level of Global DNA methylation. Moreover, C1qbp KO CD8+ T cells show hegher DNA methylation at some effector cells-signature genes.

ATAC-seq analysis of C1qbp sufficient and deficient CD8+ T cells sorted from mice post infection with LCMV Armstrong

Project description:This study is aimed to explore whether C1qbp deficiency affects the epigenetic modification during the differentiation stage of CD8+ T cells. Transferred WT and C1qbp KO P14 cells sorted from the spleen of donor mice on day 5 post-infection with LCMV Armstrong were collected and treated for ATAC-seq. ATAC-Seq analysis provided sufficient but not necessary evidence of epigenetic changes between WT and C1qbp KO CD8+ T cells. Our study have shown that, on day 5 post-infection with LCMV Armstrong, even WT and C1qbp KO CD8+ T cells have different mRNA expressing profiling, the ATAC-seq shows slight changes in chromatin accessibility of indicated genes.

RNA sequencing analysis of transferred C1qbp sufficient and deficient CD8+ T cells sorted from donor mice post infection with LCMV Armstrong

Project description:Tthis study is aimed to explore how C1qbp deficiency affects the mRNA expressing profiling during the differentiation stage of CD8+ T cells.Naïve WT and C1qbp KO P14 cells and transferred WT and C1qbp KO P14 cells sorted from the spleen of donor mice on day 3, 5, 7 post-infection with LCMV Armstrong were collected and treated for RNA-seq. RNA-Seq analysis revealed transcriptomic changes between WT and C1qbp KO CD8+ T cells. Naïve WT and C1qbp KO CD8+ T cells showed similar gene expressing profiling. On day 3, 5, 7 post-infection with LCMV Armstrong, WT and C1qbp KO CD8+ T cells showed 341, 1,164 and 437 differentially expressed genes respectively.

Transcription profiling of mouse IL-7Rhi/lo effector CD8 T cells on day 6/7 after LCMV armstrong infection

Project description:At the peak of the CD8 T cell response to acture viral and bacterial infections, expression of the Interleukin-7 Receptor (IL-7R) marks Memory Precursor Effector CD8 T Cells (MPECs) from other Short-Lived Effector CD8 T cells (SLECs), which are IL-7Rlo. This study was designed to determine the gene expression differences between these two subsets of effector CD8 T cells. Experiment Overall Design: This study compared IL-7Rhi and IL-7Rlo LCMV-specific P14 Transgenic CD8 T cells, sorted from LCMV armstrong infected recipient mice 6/7 days after infection. Data includes 3 independent replicates for the IL-7Rhi and IL-7Rlo groups.

Areas of H3K27 tri-methylation in CD8+ T cells from the spleens of LCMV-Armstrong or LCMV-Clone 13 infected mice

Project description:The profiles of H3K27 tri-methylation in CD8+ T cells from LCMV-Armstrong and LCMV-Clone 13 infected mice are known to be distinct from one another. We used CUT&RUN (Cleavage Under Targets and Release Using Nuclease) to analyze these differences in splenic CD8+ T cells of these two infection conditions.

ERRBS dataWT and TET2cKOgp33+ CD8+ T cells isolated on D8 LCMV-Armstrong infection

Project description:The epigenetic modifier TET2 plays a role in cell fate decisions in hematopeotic stem cells and CD4+ Th1 and Th17 differentiation. Here, we demonstrate that loss of TET2 promotes CD8+ memory differentiation following acute viral infection with LCMV-Armstrong.
