Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [scRNAseq]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. We conducted scRNAseq analysis on sorted virus-specific tetramer+ CD8+ T cells isolated at day 20 post-infection with chronic LCMV-Cl13 from either littermate control or EGR2 T cell conditional knock-out mice. Cells were labelled with hashtags and mixed prior to multiplexed analysis. The resulting data demonstrated that the exhausted cell subsets within EGR2 KO CD8+ T cells have an effector-like phenotype, suggesting that EGR2 stabilises the exhausted state.

Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [ATACseq]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. Flow cytometric and scRNAseq analysis indicated that EGR2 deficient CD8+ T cells had an abnormal effector-like phenotype. To examine whether this was due to epigenetic alterations, we conducted ATACseq analysis on sorted virus-specific tetramer+ CD8+ T cells isolated at day 20 post-infection with chronic LCMV-Cl13 from either littermate control or EGR2 T cell conditional knock-out mice. The resulting data demonstrated that there were substantial epigenetic changes within EGR2 KO CD8+ T cells, suggesting that EGR2 stabilises the exhausted epigenetic state.

Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [CHIP-seq]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. Flow cytometric and RNAseq analysis indicated that EGR2 deficient CD8+ T cells had a block in differentiation and failed to undergo terminal exhaustion. To examine the direct gene targets of EGR2 during exhaustion, we conducted ChIPseq analysis on enriched bulk splenic CD8+ T cells isolated at day 20 post-infection with chronic LCMV-Cl13 from C57BL/6J mice. The resulting data demonstrated that EGR2 directly controls expression of key gene targets, including Pdcd1, Tigit, Cxcr5, Tcf7, Bach2 and Bcl6.

Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [RNA-seq II]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. Flow cytometric analysis indicated that EGR2 is expressed selectively within the progenitor exhausted subset, however a subpopulation of progenitor exhausted cells did not express in EGR2. To define the differences between the EGR2+ and EGR2- progenitor exhausted cells, GFP+ and GFP- polyclonal progenitor exhausted (ie. CD44int-hiPD-1+Slamf6+Tim3-) CD8+ T cells were sorted from Egr2-GFP reporter mice at day 20 p.i. with chronic LCMV-Cl13, and analysed by RNAseq. The resulting data demonstrated that GFP- progenitor cells have a more differentiated phenotype.

Antigen-driven EGR2 expression is required for exhausted CD8+ T cell stability and maintenance [RNA-seq I]

Project description:In this study, we examined the role of the transcriptional regulator EGR2 in CD8+ T cell exhaustion during chronic viral infection. Flow cytometric analysis indicated that EGR2 deficient CD8+ T cells had a block in differentiation and failed to undergo terminal exhaustion. To confirm this at a whole transcriptome level, we conducted RNAseq analysis on sorted splenic virus-specific tetramer+ CD8+ T cells isolated at day 20 post-infection with chronic LCMV-Cl13 from either littermate control or EGR2 T cell conditional knock-out mice. The resulting data demonstrated that there was a global loss of the terminally exhausted gene signature within EGR2 KO CD8+ T cells. This suggests that EGR2 promotes terminal CD8+ T cell exhaustion.
