(Submitter supplied) Extracellular adenosine triphosphate (eATP) is a signaling molecule that affects T cell function via the ionotropic P2X7 receptor. The study of effector/memory T cells isolated from mice with deletion of P2rx7, the gene encoding for P2X7, allowed understanding the impact of P2X7 activity on T cell function in the eATP-rich tumor microenvironment. To explore the the transcriptional impact of the lack of P2rx7 in CD4+ naïve and TEM cells, we performed genome-wide expression profiling of ex vivo purified CD4+ naïve and TEM cells from WT and P2rx7-/- mice

(Submitter supplied) We report the application of Illumina Hi-Seq sequencing technology for high-throughput profiling of Cbx3/HP1g deposition in mammalian CD8+ effector T cells. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, genome-wide chromatin-state maps of mouse wt CD8+ effector T cells were generated. We find that Cbx3/HP1g negatively regulates the germinal center and high-affinity antibody responses in a CD8+ T-cell-dependent manner. more...

(Submitter supplied) As sufficient extracellular arginine is crucial for T cell function, depletion of extracellular arginine by elevated Arginase 1 (Arg1) activity has emerged as a hallmark immunosuppressive mechanism. However, the potential cell-autonomous roles of arginases in T cells have remained unexplored. Here we show that the arginase isoform expressed by T cells, the mitochondrial Arginase 2 (Arg2), is a cell-intrinsic regulator of CD8+ T cell activity. more...

(Submitter supplied) We used single-cell mRNA sequencing to analyze the response of tumor-specific CD4+ tumor infiltrating lymphocytes (TILs) and draining lymph node (dLN) T cells. Computational approaches to characterize subpopulations identified TIL transcriptomic patterns strikingly distinct from acute and chronic anti-viral responses and dominated by diversity among T-bet-expressing T helper type 1 (Th1)-like cells. more...

(Submitter supplied) Using 4 primary melanoma cell lines for which autologous tumor-infiltrating T lymphocytes (TILs) were available, a screen of clinically-relevant small-molecule inhibitors (SMIs) was performed to find SMIs that could synergistically enhance tumor cell killing by autologous TILs. Among positive results were SMIs targeting topoisomerase I (TOP1) or HSP90. Of note, as implied by the fact that these SMIs had synergistic effects, there was relatively little direct cytotoxicity of the SMIs when used alone. more...

(Submitter supplied) Adoptive cell immunotherapy (ACT) using autologous tumor-infiltrating lymphocytes (TIL) can result in complete regression of advanced melanoma in some patients, but the efficacy of this potentially curative therapy is limited by poor persistence of TIL after adoptive-transfer. Pharmacologic inhibition of the serine/threonine kinase Akt has recently been shown to promote immunologic memory in viral-specific murine models, but whether this approach may enhance features of memory (e.g. more...

(Submitter supplied) Identifying signals in the tumor microenvironment (TME) that shape CD8+ T cell phenotype can inform novel therapeutic approaches for cancer. Here, we identified a gradient of increasing glucocorticoid receptor (GR) expression and signaling from naive to dysfunctional CD8+ tumor-infiltrating lymphocytes (TILs). Conditional deletion of the GR in CD8+ TILs resulted in improved effector differentiation, reduced TCF-1 expression, and failure to develop dysfunctional phenotype, culminating in tumor growth inhibition. more...

(Submitter supplied) The quantity and quality of tumor-infiltrating lymphocytes (TILs), particularly CD8+ T cells, are parameters linked to tumor control and response to immunotherapy. Yet, it is unknown whether these parameters are controlled in a circadian manner. Here, we show in murine and human cancers that the phenotype and number of TILs show time-of-day differences, which are driven by rhythmic leukocyte infiltration and depend on the circadian clock machinery. more...

(Submitter supplied) Terminally exhausted CD8+ T-cells, which hold certain level of anti-tumour cytotoxicity but largely reduced proliferation capacity, contribute directly to tumour growth control. However, this subpopulation do not respond to immune checkpoint blockades or most existing immunotherapies and are difficult to be reactivated. Here, we show that a half-life extended interleukin (IL)-10/Fc fusion protein directly expands the terminally exhausted CD8+ TILs and sustains their effector functions through in vivo metabolic reprogramming, leading to eradication of established solid tumours and durable cures in a majority of treated mice when combined with adoptive T-cell transfer immunotherapy. more...

(Submitter supplied) Recent work has shown that cytotoxic T cells play a central role in immune-mediated control of cancers1-3, and monoclonal antibodies that target inhibitory receptors on T cells can induce significant clinical benefit in patients despite advanced disease4-6. However, many of the regulatory pathways that result in loss of T cell function within immunosuppressive tumors remain unknown. Here we show that such regulatory mechanisms can be systematically discovered in vivo in the tumor microenvironment. more...

(Submitter supplied) Metabolism of chimeric antigen receptor (CAR) T cells is emerging as an important area to improve CAR-T cell therapy in cancer treatment. Mitochondrial respiration is essential for survival and function of CAR-T cells, but developing strategies to specifically enhance mitochondrial respiration has been challenging. Here we identify MCJ/DnaJC15, an endogenous negative regulator of mitochondrial Complex I, as a metabolic target to enhance mitochondrial respiration in CD8 CAR-T cells. more...
