(Submitter supplied) The goal of this study was to identify the molecular programming using ATAC-seq of CD8 T cells responding to different viral infections. Mice were infected with either LCMV Armstrong to model an acute infection or LCMV Clone-13 to model a chronic infection. At various time points following infection, virus-specific CD8 T cells were purified and ATAC-seq performed. These data identify the changes in chromatin accessibility associated with acute infections and the establishment of functional memory versus those accessibility changes associated with chronic infection.

(Submitter supplied) Wnt signal transduction during an immune response is involved in the establishment of functional CD8 T cell memory P14 ConductinLacZ CD8 T cells (CD45.2) were transferred in CD45.1+.2+ recipient mice. The day after, recipients were infected with 200pfu LCMV WE. At day 8 after infection, cells from spleen and lymph nodes were harvested, magnetically enriched for CD8 T cells, loaded with the beta-galactosidase substrate (FDG) and sorted as 7AAD-negative CD45.- negative, beta-galactosidase positive versus negative 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...

(Submitter supplied) In response to acute infection, naive CD8+ T cells expand, differentiate into effector cells and then contract to a long-lived pool of memory cells after pathogen clearance. During chronic infections or in tumors, CD8+ T cells acquire an “exhausted” phenotype. Here we present genome-wide comparisons of chromatin accessibility and gene expression from endogenous CD8+ T cells responding to acute and chronic viral infection using ATAC-seq and RNA-seq. more...

(Submitter supplied) During chronic stimulation T cells acquire an exhausted phenotype characterized by expression of multiple inhibitory receptors and down-modulation of effector function. While this is required for the protection of the organism from excessive immunopathology, it also prevents successful immunity against persistent viruses or tumor cells. Here we demonstrate that CD8+ T cell exhaustion is characterized by a progressive decline in cellular metabolism. more...

(Submitter supplied) Antigen-specific effector CD8+ T cells deficient in Blimp-1 (Prdm1) do not acquire maximal effector functions, evade terminal differentiation, and more rapidly acquire some hallmark properties of memory CD8+ T cells. In this study, we compared the gene expression profiles of wildtype and Prdm1-/- LCMV-specific effector CD8+ T cells to better understand the molecular mechanisms underlying this striking phenotype.

(Submitter supplied) We have recently defined a novel population of PD-1+TCF1+virus-specific CD8 T cells that function as resource cells during chronic LCMV infection and provide the proliferative burst seen after PD-1 blockade. Such CD8 T cells have been found in other chronic infections and also in cancer in mice and humans. These CD8 T cells exhibit stem-like properties undergoing self-renewal and also giving rise to the terminally differentiated (exhausted) CD8 T cells. more...

(Submitter supplied) Exhausted T cells express multiple co-inhibitory molecules that impair their function and limit immunity to chronic viral infection. Defining novel markers of exhaustion is important both for identifying and potentially reversing T cell exhaustion. Herein, we show that the ectonucleotidse CD39 is a marker of exhausted CD8+ T cells. CD8+ T cells specific for HCV or HIV express high levels of CD39, but those specific for EBV and CMV do not. more...

(Submitter supplied) T cell dysfunction is an important feature of many chronic viral infections. In particular, it was shown that PD-1 regulates T cell dysfunction during chronic LCMV infection in mice and PD-1 high cells exhibit an intense exhausted gene signature. These findings were extended to human chronic infections such as HIV, HCV and HBV. However, it is not known if PD-1 high cells of healthy humans have the traits of exhausted cells. more...

While the relevance of Trm in diverse diseases ranging from infection to cancer is appreciated, the development and functional heterogeneity of Trm remain poorly understood. Using single-cell RNA-sequencing (scRNA-seq) and genetic reporter mice, we identified discrete lineages of intestinal antigen-specific CD8+ T cells, including a Blimp1hiId3lo tissue-resident effector cell population most prominent in the early phase of acute viral and bacterial infections, and a molecularly distinct Blimp1loId3hi tissue-resident memory population that subsequently accumulated at later infection timepoints. more...

(Submitter supplied) CD8 T cells play an essential role in defense against viral and bacterial infections and in tumor immunity. Deciphering T cell loss of functionality is complicated by the conspicuous heterogeneity of CD8 T cell states described across different experimental and clinical settings. By carrying out a unified analysis of over 300 ATAC-seq and RNA-seq experiments from twelve independent studies of CD8 T cell dysfunction in cancer and infection we defined a shared differentiation trajectory towards terminal dysfunction and its underlying transcriptional drivers and revealed a universal early bifurcation of functional and dysfunctional T cell activation states across models. more...
