(Submitter supplied) CD8 T cells are the main effectors of the adaptive immune response against intracellular pathogens and cancer. Chronic antigen stimulation and inflammation lead to CD8 T cell differentiation and function that differ from those generated during acute infections. A comprehensive definition of the heterogeneity existing within both tumor-specific and total CD8 tumor-infiltrating T cells remains to be clearly established. more...

(Submitter supplied) Persistent exposure to high levels of antigen results in the progressive exhaustion of T cells and has been thought to preclude the formation of memory. In contrast to the latter assumption, we show here that tumor-specific CD8 T cells residing in the tumor microenvironment include a Tcf1 expressing sub population that has key characteristics of central memory cells, lack an effector cell signature but display hallmarks of exhausted T cells, including the expression co-inhibitory receptors such as PD1. 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 chronic infections and cancer, exhausted CD8 T cells exhibit heterogeneous subpopulations. TCF1+PD-1+ progenitor exhausted CD8 T cells (Tpex) can self-renew and give rise to Tim-3+PD-1+ terminally differentiated CD8 T cells that retain their effector functions. Tpex cells are thus essential to maintaining a pool of antigen-specific CD8 T cells during persistent antigenic stimulation, and only they respond to PD-1-targeted therapy. more...

(Submitter supplied) Differential responses to immune checkpoint inhibitors (ICI) may be attributed to tumor-intrinsic factors or environmental cues; however, these mechanisms cannot fully explain the variable ICI responses in different individuals. Here, we investigate the potential contribution of immunological heterogeneity with a focus on differences in T-cell receptor (TCR) repertoire to ICI responses, which has not been defined previously.

(Submitter supplied) Identifying tumor antigen-specific T cells from cancer patients has been a goal of tumor immunologists for several decades. Co-expression of CD103 and CD39 on CD8 TIL highly enriches for tumor-reactive T cells. CD39+CD103+ CD8 TIL have a distinct TCR repertoire compared to other CD8 TIL subsets and are clonally expanded within the tumor. They are highly enriched for tumor antigen recognition and efficiently killed autologous tumor cells. more...

(Submitter supplied) CD8+ tumor-infiltrating lymphocytes (TILs) comprise phenotypically and functionally heterogeneous subpopulations. Of these, effector memory CD45RA-expressing CD8+ T cells (Temra) have been discovered and characterized as the most terminally differentiated subset. However, their exact ontogeny and physiological importance in association with tumor progression remain poorly understood. We analyzed primary tumors and peripheral blood samples from 26 patients with non-small cell lung cancer and analyzed their phenotypes and functional characteristics using flow cytometry, RNA-sequencing, and bioinformatics. more...

(Submitter supplied) Bispecific T-cell engagers (TCEs) show promising clinical efficacy in blood tumors, but their application to solid tumors with immunosuppressive environments remains challenging. Here, we show that Fc-fused IL-7 (rhIL-7-hyFc) changes the intratumoral CD8 T cell landscape, allowing TCE-immunotherapy to function effectively in solid tumors. In order to explore the transcriptomic changes induced by rhIL-7-hyFc or a combination of rhIL-7-hyFc and TCE treatment at the clonal level, we performed scRNA/TCR-seq.
