(Submitter supplied) T cell exhaustion is a progressive loss of effector function and memory potential due to persistent antigen exposure, which occurs in chronic viral infections and cancer. Here we investigate the relation between gene expression and chromatin accessibility in CD8+ tumor-infiltrating lymphocytes (TIL) that recognize a model tumor antigen and have features of both activation and functional exhaustion. By filtering out accessible regions observed in bystander, non-exhausted, TIL and in acutely restimulated CD8+ T cells, we define a pattern of chromatin accessibility specific for T cell exhaustion, characterized by enrichment for consensus binding motifs for Nr4a and NFAT transcription factors. Anti-PD-L1 treatment of tumor-bearing mice results in cessation of tumor growth and partial rescue of cytokine production by the dysfunctional TIL, with only limited changes in gene expression and chromatin accessibility. Our studies provide a valuable resource for the molecular understanding of T cell exhaustion in cancer and other inflammatory settings.

(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) An improved understanding of the anti-tumor CD8+ T cell response after checkpoint blockade would enable more informed and effective therapeutic strategies. Here we examined the dynamics of the effector response of CD8+ tumor-infiltrating lymphocytes (TILs) after checkpoint blockade therapy. Bulk and single-cell RNA profiles of CD8+ TILs after combined Tim-3+PD-1 blockade in preclinical models revealed significant changes in the transcriptional profile of PD-1? TILs. more...

(Submitter supplied) Although understanding of T-cell exhaustion is widely based on mouse models, its analysis in cancer patients could provide clues indicating tumor sensitivity to immune checkpoint blockade (ICB). Data suggests a role for costimulatory pathways, particularly CD28, in exhausted T-cell responsiveness to PD-1/PD-L1 blockade. Here, we used single-cell transcriptomic, phenotypic, and functional approaches to dissect the relation between CD8+ T-cell exhaustion, CD28 costimulation, and tumor specificity in head and neck, cervical, and ovarian cancers. more...

(Submitter supplied) In contrast to its inhibitory effects on many cells, IL-10 activates CD8+ tumor infiltrating lymphocytes (TILs) and enhances their antitumor activity. However, how IL-10 globaly regualte TIL CD8+ T cell function is stil not clear. To understand the transcriptional regulation of TIL CD8+ T cell by IL-10, we performed a microarray analysis using in vitro expanded HUMAN LUNG CANCER TIL CD8 T cells with or without IL-10.

(Submitter supplied) Cooperative interactions among transcription factors are essential for gene transcription. We previously showed that NFAT and AP-1 (Fos-Jun) transcription factors cooperate to promote the effector functions of T cells, but that under conditions where it is unable to cooperate with AP-1, NFAT imposes a negative feedback programme of T cell hyporesponsiveness (“exhaustion”). Here we show that BATF and IRF4 cooperate to counter T cell exhaustion. more...
