Early Transient IFN-γ Production-dependent and Independent Mechanisms Underlie the Cross-protectivity of Lung-Resident Memory CD8 T Cells against Respiratory Virus Challenge

Project description:Transcriptome profiling of lung tissues and lung CD8+ TRM during early phase of infection to investigate the mechanism of lung TRM cells during antigen re-exposure within 48hours. After P14 T cell transfer, PR8 infection would not induce P14 TRM cells, while PR8-gp33 would. Comparing the gene expression of lung tissues after LCMV Armstrong challenge at day 30 after PR8 or PR8-gp33 infection would help us understand the function of lung CD8+ TRM cells. Sorted TRM cells from mice challenged with LCMV Armstrong at day 30 after PR8-gp33 infection would reveal the activation mechanism of TRM cells.

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.

Expression Data from Memory P14 Tg CD8 T cells after either saline mock-infection, Pichinde Virus Infection (bystander infection) or Pichinde Virus infection with daily treatment with anti-CD122 (clone TM-b1)

Project description:Exposure to inflammatory cytokines driven by bystander cytokines can have profound effects on the function of memory CD8 T cells. Here we transferred a 1-5X10^4 of P14 TCR-tg T cells (specific for gp33-41 of LCMV) on day -1 followed by infection with 2X10^5 PFU of LCMV Armstrong ip to generate memory P14 populations. Mice were rested for >50 days before further challenge. Mice containing memory P14 populations were either mock-infected with saline, infected with 2X10^6 Pichinde Virus ip (no cross-reactivity wtih LCMV gp33-41) or infected with 2X10^6 Pichinde Virus ip together with daily injections of 200 micrograms of anti-CD122 antibody (clone TM-b1). On day 4 following indicated treatments P14s were flow sorted and RNA was extracted from 1X10^6 cells using an RNeasy kit (Qiagen). Each group had 3 biological replicates. Transcriptomes were compared by DAVID analysis (p<0.01, Fold-Change > 1.5) 3 biological replicates per group. Groups included P14 from mock-infected mice, P14 from Pichinde virus infected mice and P14 from Pichinde virus and anti-cd122 treated mice.

miRNA signatures of antigen specific CD8+ T cells at different stages of immune response to LCMV infection

Project description:miRNAs play an important role in regulating CD8+ T cell response. We used the microarray approach to profile the miRNA signatures of naïve, day 5 effector, day 8 effector, and memory CD8+ T cells. We identified a miRNA signature associated with rapidly proliferating effector CD8+ T cells. CD8+ T cells from P14 TCR transgenic mice were transferred to C57BL6 recipients which were subsequently infected with LCMV Armstrong. Donor P14 CD8+ T cells were sorted on day 5, day 8, or >day 60 post-infection. Naïve P14 CD8+ T cells were sorted directly from naive P14 splenocytes. The total RNA including miRNAs was extracted from sorted samples, labeled, and hybridized to Agilent Mouse miRNA microarray.

Tox reinforces the phenotype and longevity of exhausted T-cells in chronic viral infection [day 8 acute vs chronic]

Project description:Chronic CD8 T-cell stimulation in persisting infections or tumors can induce a stable gene expression program, known as T-cell dysfunction or exhaustion, that limits the cell’s effector functions and anti-viral and anti-tumor immunity. Thus far, the underlaying molecular mechanisms that induce and stabilize this phenotype are vaguely understood. We report here that establishing this program requires the thymocyte selection-associated high mobility group-box protein (Tox). Genetic disruption of Tox augments effector function, decreases the expression of PD-1, and significantly enhances immunopathology. These changes are linked to a failure in fixing the dysfunctional phenotype in the critical Tcf1+ progenitor population and to impaired epigenetic programing. Surprisingly, the gains in effector function co-incide with declining numbers of Tcf1+ cells and result ultimately in reduced total numbers of pathogen-specific T-cells. Thus, we establish Tox as a critical factor for the development of T-cell dysfunction and establish a clear link between CD8 T-cell intrinsic suppression of effector function and protection against immune-pathology. The terms acute and chronic samples refer to P14 T-cells that were initially activated in acute LCMV (Armstrong) or chronic LCMV (clone-13) infections. 4 weeks later, the P14 T cells were collected, transferred into naive mice, and both then re-expanded in acute LCMV (Armstrong) infection. 8 days later P14 T-cells were collected and analysed.

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.

CUT-tag analysis of C1qbp sufficient and deficient CD8+ T cells

Project description:This study is aimed to Investigate whether C1qbp deficiency affects the histone 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 CUT-tag. CUT-tag-Seq analysis provided evidence of histone modification changes between WT and C1qbp KO CD8+ T cells. Our study shows that on day 5 post-infection with LCMV Armstrong, along with mRNA expressing profiling, the CUT-tag-seq exhibits obvious changes in H3K27me3 and H3K27Ac modification of indicated genes of WT and C1qbp KO CD8+ T cells.
