Cytotoxic Tissue-Resident NK Cells Infiltrate and Control Solid Epithelial Tumor Growth [CITE-Seq]

ABSTRACT: Human tissue-resident natural killer (trNK) cells – broadly defined by markers of tissue-residency, such as CD49a (integrin alpha1, ITGA1) and CD103 (integrin alpha E, ITGAE) – are increasingly recognized for their immunoregulatory role in host control of infection, malignancy, and autoimmunity. Although the importance of transforming growth factor beta (TGFβ) in trNK cell differentiation has been demonstrated, the context in which the differentiation of CD49a+CD103+ trNK cells occurs can result in either an immunosuppressive phenotype or a highly cytotoxic one. To understand this dichotomy better, we utilized a multiomics approach to molecularly characterize these cells and identified a highly cytotoxic trNK (ctrNK) cell phenotype, characterized by the expression of CD39.

RNA sequencing of NK cells in human lung

Project description:Human lung tissue-resident NK cells (trNK cells) are likely to play important roles in viral infections, inflammation and cancer. However, knowledge about lung trNK cells is lacking but is fundamental for exploiting these cells in therapeutic approaches. Here we analysed the transcriptome of CD69+CD49a+CD103+CD16-CD56bright, CD69+CD49a+CD103-CD16-CD56bright, CD69+CD49a-CD103-CD16-CD56bright, CD69-CD49a-CD103-CD16-CD56bright, and CD56dimCD16+NKG2A+CD57- NK cells isolated from human lung.

RNAseq of restimulated lung CD8 T cells 21 days post influenza A infection

Project description:We report the RNA sequencing of both non-restimulated and restimulated (using anti CD3/CD28 cross-linking) antigen-experienced (CD44+) mouse lung CD8 T cells 21 days post X31 influenza A infection subsetted by integrin expression of CD49a and CD103. After restimulation, all four subsets (CD49a+CD103+, CD49a+CD103-,CD49a-CD103+, CD49a-CD103-) demonstrate global differences and separate in principle component analysis space, with CD49a+ groups showing elevated transcripts for a number of effector functions. The non-restimulated T cells separate out into CD49a+CD103+/- and CD49a-CD103+/- groups. CD49a serves as a correlate of effector transcripts in mouse lungs to a greater degree than CD103 in both non-restimulated and restimulated conditions.

CD49a expression and induction of cytotoxicity on human tissue-resident CD8+ T cells is controlled by RUNX2 and RUNX3 transcription factor activity [ATAC-seq]

Project description:CD49a marks highly cytotoxic epidermal tissue-resident memory (TRM)-cells, but their molecular circuitry and relationships to circulating populations are poorly defined. We demonstrate enrichment of RUNX family transcription factor binding motifs in human epidermal CD8+CD103+CD49a+ TRM-cells, paralleled by high RUNX2 and RUNX3 protein expression. Clonal overlap between epidermal CD8+CD103+CD49a+ TRM-cells and circulating memory CD8+CD45RA–CD62L+ T-cells identified a reservoir of circulating cells with potential to seed cytotoxic TRM-cells in new sites. Upon IL-15 and TGF-β stimulation, subsets of circulating CD8+CD45RA–CD62L+ T-cells acquired CD49a expression and cytotoxic transcriptional profiles in a RUNX2 and RUNX3 dependent manner. In contrast, knock-out of RUNX3, but not RUNX2, prevented CD103 expression. In melanoma, high RUNX2, but not RUNX3, transcription correlated with a cytotoxic CD8+CD103+CD49a+ TRM cell signature and overall patient survival. Together, our results indicate that combined RUNX2 and RUNX3 activity promotes the differentiation of cytotoxic CD8+CD103+CD49a+ TRM-cells, providing immunosurveillance of infected and malignant cells.

TGF-beta and IL-12 conversely orchestrate formation of CD103+ CD8 tumor-resident memory T cells to regulate response to therapeutic cancer vaccine [RNA-Seq]

Project description:Using mouse model, we show that CD8 tumor-infiltrating T lymphocytes (TIL) include two major resident T cells subpopulations expressing either CD49a or CD103 integrin, with a subset co-expressing CD103 and Tcf-1 transcription factor. Tumor vaccination induces a decrease in the percentage of Tcf-1+CD103+ TRM-like cells and an expansion of CD49a+ TRM displaying an effector/exhausted profile. Tcf-1+CD103+ TRM-cell density increases in tumors from vaccinated transgenic mice constitutively expressing active TGF-beta-type-2-receptor and wild-type mice challenged with neutralizing anti-IL-12 antibodies. Stimulation of mouse and human CD8 T cells with recombinant (r)TGF-beta combined with anti-CD3 antibodies results in increase in the proportion of CD103+ and Tcf-1+CD103+ CD8 T cells, whereas rIL-12 induces decrease in CD103 expression on CD8 T cells.

CD39+ CD4+ conventional T cells with exhaustion traits and cytotoxic potential infiltrate tumors and expand upon CTLA4 blockade

Project description:CD4+ conventional T (Tconv) lymphocytes display an important role in tumor immunity; however, their contribution to tumor elimination remains poorly understood. Here we describe a subset of tumor-infiltrating Tconv cells characterized by the expression of CD39. In mouse cancer models CD39+ Tconv cells accumulate with tumor growth but are absent in lymphoid organs. Compared to tumor CD39- Tconv cells, CD39+ cells exhibit a cytotoxic and exhausted signature at the transcriptomic level, confirmed by high protein expression of co-inhibitory receptors and transcription factors related to exhaustion. Additionally, CD39+ Tconv cells show an increased production of INFg, Granzyme B, Perforin and CD107a, but a reduced production of TNF upon in vitro stimulation. In vivo, CTLA-4 blockage induces the expansion of CD39+ Tconv cells in the tumor, while maintaining their features of cytotoxicity and exhaustion. In breast cancer patients, CD39+ Tconv cells are found in tumors, and at lower frequency in the adjacent non-tumoral mammary tissue. CD39+ Tconv cells are also present in metastatic but not detected in non-metastatic lymph nodes and blood. Human tumor CD39+ Tconv cells constitute a heterogeneous cell population with features of exhaustion, impaired TNF production, and high expression of co-inhibitory receptors and CD107a. High gene expression of CD4 and ENTPD1 (CD39) in human tumor tissues correlates with higher overall survival rate in breast cancer patients. Our results identify CD39 as a biomarker of CD4+ T cells with characteristics of both exhaustion and cytotoxic potential and put forward CD39+ Tconv cells as pivotal players of the immune response against tumors.

RNA-seq transcriptome analysis of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- T cells from healthy human skin

Project description:We report the transcriptome analysis of epidermal CD8 tissue resident memory T (TRM) cells from healthy human skin. Specifically, epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells from healthy human skin were sorted by FACS. Differential gene expression analysis revealed functional dichotomy of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells.

scRNAseq and scTCRseq data from tumor-infiltrating lymphocytes

Project description:In cancer models, CD103+CD8 TRM cells are implicated in the response to anti-PD-1 immunotherapy, and a subset of CD4 TRM cells expressing the integrin CD49a is required for response to anti-CTLA-4 immunotherapy. We performed single-cell RNA sequencing on tumour-infiltrating T lymphocytes (TILs) isolated from colon carcinoma et unsupervised analyses reveal several TRM populations.

Transcriptome profile of naive CD8 T cells from WT and CD103 deficient mice

Project description:The Ly6C–CXCR3– naïve CD8 T cells highly express CD103. To understand the biological significance of CD103 expression on naïve CD8 T cells, we performed RNA sequencing on sorted naïve CD8 T cells from WT and CD103-dificient (Itgae–/–) mice to elucidate the function of CD103 expressed on naïve CD8 T cells.
