(Submitter supplied) During a viral infection, CD8 T cells encounter a myriad of antigenic and inflammatory signals of variable strength, which sets off each individual T cell on a unique differentiation trajectory. However, the developmental path for each of these cells will ultimately lead to one of only two potential outcomes after clearance of the infection—death or survival and development into memory CD8 T cells. How this cell fate decision is made remains incompletely understood. In this study, we explore the dynamic transcriptional changes during effector and memory CD8 T cell differentiation at the single cell level.

(Submitter supplied) The transcription factor Inhibitor of DNA binding 2 (Id2) modulates T cell fate decisions but the molecular mechanism underpinning this regulation is unclear. Here, using whole genome mRNA analysis we show that loss of Id2 programs CD8+ T cells to adopt a memory fate with increased Eomesodermin and Tcf7 expression. Our findings reveal that the Id2-E2A axis orchestrates T cell differentiation through the induction or repression of downstream transcription factors essential for effector and memory T cell differentiation.

(Submitter supplied) We speculated that distinct levels of Id2 was deterministic in the transcriptional program of antigen-specific CD8+ T cells. To test this hypothesis, we subjected DbNP366-specific effector CD8+ T cells purified according to their differential expression of Id2-GFP (Id2-GFPint and Id2-GFPhigh) to microarray analysis and compared their gene expression profiles to the differentially expressed genes identified by comparing Id2-deficient and wild-type DbNP366-specific CD8+ T cells. more...

(Submitter supplied) T-bet is critical for cytotoxic T lymphocyte (CTL) differentiation, but it is unclear how it operates in a graded manner in the formation of both terminal effector and memory precursor cells during infection. We find that at high concentrations T-bet induced expression of Zeb2 mRNA, which then triggered CTLs to adopt terminally differentiated states. ZEB2 and T-bet cooperate to switch on a terminal CTL differentiation program, while simultaneously repressing genes necessary for central memory CTL development. more...

(Submitter supplied) Our experiments aimed to investigate the landscape of enhancers and super-enhancers in naïve, effector and memory CD8+ T cells. Here we mapped four histone modification marks and gene expression in naive, effector, and memory cells after viral infection. Our results suggest that the chromatin environment at regulatory DNA sequences in TCM is more permissive than in TN and TE. We further predicted the enhancers and their targets, and constructed transcriptional regulatory networks (TRNs) in three T cell stages. more...

(Submitter supplied) During microbial infection, responding CD8+ T lymphocytes differentiate into heterogeneous subsets that together provide immediate and durable protection. To elucidate the dynamic transcriptional changes that underlie this process, we applied a single-cell RNA sequencing approach and analyzed individual CD8+ T lymphocytes sequentially throughout the course of a viral infection in vivo. Our analyses revealed a striking transcriptional divergence among cells that had undergone their first division and identified previously unknown molecular determinants controlling CD8+ T lymphocyte fate specification, including Ezh2, the catalytic component of the Polycomb Repressive Complex 2. more...

(Submitter supplied) Mouse CD8+ T cells affected by ID3 (Inhibitor of DNA binding 3) display patterns of gene expression suggesting enhanced persistance and survival. In this study, we identified genes differentially expressed between ID32a transduced and mock transduced, and ID32a knockout and wild type mouse CD8+ T cells. Most prominent functions of differentially expressed genes include DNA replication-associated repair, maintenance of chromosome stability and mitotic cell divison machinery. more...

(Submitter supplied) To understand epigenetic mechanisms underlying CD8 T cell differentiation, we performed ChIP-seq of 4 histone modifications (H3K4me1, H3K4me3, H3K27ac, H3K27me3) and ATAC-seq to probe chromatin states and accessibility. We identified subset-specific regulatory elements (enhancers and promoters) from chromatin states and predicted key transcription factors from accessible regulatory regions using ATAC-seq.

(Submitter supplied) Differentiation of naive T cells into effector and memory populations following infection is mediated by a network of transcription factors (TF) that translate environmental signals into regulatory circuits involving TF expression and binding activity as well as chromatin accessibility. To delineate the transcriptional difference between effector subsets, we performed microarray on TE and MP subsets and found that TE and MP subsets reflect transcriptional differences between effector and memory CD8+ T cells

(Submitter supplied) Stable changes in chromatin states and gene expression in cells of the immune system form the basis for their memory of infections and other challenges. We used naturally occurring cis-regulatory variation in wild-derived inbred mouse strains to explore the mechanisms underlying long-lasting vs. transient gene regulation in antigen-specific CD8 T cells responding to acute viral infection. Our observations provide novel insights into the mechanisms driving stable and reversible transcriptional and epigenetic memory in virus-specific CD8 T cells. more...
