Single-cell RNA-sequencing of immune cells (CD45+) from the tumor microenvironment

ABSTRACT: In mouse models of PDGF-driven glioma where Notch is tumor-suppressive, we find that Notch activity shapes interferon-response in tumor cells and the local immune microenvironment early during tumor progression. Notch inhibition disturbs cytokine expression by tumor cells, altering recruitment and activation of immune cell populations and favoring hyper-proliferative "immune niche" independent growth. Genetic inactivation of Notch in glioma cells also attenuates their response to interferon-gamma establishing a non-cell autonomous inhibitory feedback loop that further promotes immune evasion and aggressiveness. Hence, we propose that Notch signaling levels in tumor cells are key to orchestrate immune escape and microenvironment independency during brain tumor formation.

Expression data for tumor-infiltrating CD45+ cells

Project description:Regulatory T (Treg) cells are crucial for immune homeostasis but they also contribute to tumor immune evasion by promoting a suppressive tumor microenvironment (TME). Mice with Treg cell-restricted Neuropilin 1 deficiency show tumor resistance while maintaining peripheral immune homeostasis, thereby providing a controlled system to interrogate the impact of intratumoral Treg cells on the TME. Using this and other genetic models, we showed that Treg cells shaped the transcriptional landscape across multiple tumor-infiltrating immune cell types. Treg cells suppressed CD8+ T cell secretion of interferon- (IFN), which would otherwise block the activation of sterol regulatory element-binding protein 1 (SREBP1)-mediated fatty acid synthesis in immunosuppressive (M2-like) tumor-associated macrophages (TAMs). Thus, Treg cells indirectly but selectively sustained M2-like TAM metabolic fitness, mitochondrial integrity and survival. SREBP1 inhibition augmented the efficacy of immune checkpoint blockade, suggesting that targeting Treg cells or their modulation of lipid metabolism in M2-like TAMs could improve cancer immunotherapy. Microarray gene expression assay was performed to interogate the impact of fragile (Nrp1–/–) Tregs on the gloabal transcriptome oftumor immune infiltrates (CD45+ cells) at various time points over the course of tumor growth.

The Glioma-Infiltrating T Cell Receptor Repertoire

Project description:While immune signaling has emerged as a defining feature of the glioma microenvironment, local selection of responding T cells and their anti-tumor potential as a population are difficult to measure directly in patients. High-throughput sequencing of T cell receptor repertoires (TCRseq) provides a population-wide statistical description of how T cells respond to disease. Here, we define new immunophenotypes in glioma based on TCRseq and RNA-Seq of tumor tissue, non-neoplastic brain tissue, and peripheral blood from patients. Using information theory, we characterize antigen-driven selection in glioma and its relationship with the expression of distinct immune-functional pathways in the tumor microenvironment. Finally, we identify a strong relationship between usage of certain TCR in peripheral blood and the divergence of the infiltrating T cell population from the peripheral repertoire. We anticipate that these immunophenotypes will be foundational to monitoring and predicting response to anti-glioma vaccines and immunotherapy. We characterized the T cell receptor (TCR) repertoires of 11 high-grade glioma patients, three low-grade glioma patients, and thee non-glioma patients by TCRseq of brain-infiltrating T cells and matching peripheral blood. In addition, we obtained gene expression profiles from brain tissue of each patient by RNA-Seq. We additionally measured the TCR repertoires exclusively from peripheral blood of one additional non-glioma patient.

TSA Breast Cancer Wild-type or RIPK1 Deletion Tumors Single-Cell RNA Sequencing Data for CD45+ and CD45- Cell Types

Project description:We found that expression of RIPK1 by cancer cells drives resistance to immune checkpoint blockade therapy. The goal of this study was to evaluate the effects of deletion of RIPK1 in the cancer cells on the tumor immune microenvironment by using single-cell RNA sequencing to evaluate defining transcriptomic features of immune subsets in the tumor microenvironment, as well as to look at corresponding gene expression changes in the immune and non-immune subsets upon RIPK1 deletion. Wild-type (WT) tumors were sequenced as a control and gene expression patterns were compared to tumors derived from RIPK1 knockout (KO) cancer cells.

Inflammation and lymphocyte infiltration are associated with shorter survival in patients with high-grade glioma

Project description:Glioma represents a serious health burden in terms of morbidity and mortality. The prognostic significance of the lymphoid and myeloid infiltrates in glioma is not clearly determined. Moreover, the characterization of different leukocyte subsets in the tumor microenvironment relies mainly on immunohistochemistry observations, and data about their association with prognosis are contradictory. Here, we performed acomprehensive study of both the tumor-infiltrating and circulating immune compartments of patients with high-grade glioma. We identified prognostic tumor and peripheral immune signatures, which associate increased inflammation, immune infiltration and activation with shorter overall survival in high-grade glioma patients. Importantly, we confirmed our observations by flow cytometry analysis and validated the tumor-signature using the TCGA dataset. In addition, both tumor genotype and grade associated with the degree of glioma immune infiltration. Unlike in the majority of cancers, lymphocyte infiltration at the tumor site is anegative prognostic factor in glioma, suggesting the ambivalent pro-tumorigenic role of immune responses in glioma.

salivary duct carcinoma genomics

Project description:Salivary duct carcinoma is a rare and aggressive salivary gland cancer subtype with poor prognosis. Its mutational landscape has been described rather exhaustively but little is known regarding its functional genomics and tumor microenvironment. In this study, we combined transcriptomics and proteomics to obtain a first characterization of deregulated pathways, which revealed the importance of Notch, TGB-β, and interferon-γ signaling. We then associated computational biology, immunohistochemistry, multiplexed immunofluorescence, and digital imaging to start charting the cellular network within the microenvironment, identify two well-defined groups of tumors according to their immune infiltrate, find novel SDC immune checkpoints, and show the role macrophages and NK cells in immunosuppression. Furthermore, we showed a clear trend between recurrence free survival and M2 macrophage abundance, and, independently, α-SMA abundance – a measure of desmoplastic stromal reaction. Altogether, these many findings open new perspectives for SDC. Classical patient stratification according to the immune infiltrate should be applied before choosing an immunotherapy. The microenvironment offers new actionable targets such as macrophages or NK cells, or even fibroblasts or hyaluronic acid in the absence of immune infiltrate. Related therapies are developed e.g. against pancreatic tumors that could inspire equivalents for SDC. Combinations with drugs targeting SDC mutated genes might also contribute to patient-specific regimens.

Tumor-associated monocytes promote mesenchymal transformation through EGFR signaling in glioma

Project description:The role of brain immune compartments in glioma evolution remains elusive. We profiled immune cells in glioma microenvironment and the matched peripheral blood from 11 patients at a single-cell level. Notably, glioblastoma exhibits specific infiltration of certain blood-originated monocytes expressing EGFR ligands including EREG and AREG, coined as tumor-associated monocytes (TAMo). TAMo infiltration is mutually exclusive with EGFR alterations (P = 0.019), while co-occurring with mesenchymal subtype (P = 4.7x10-7) and marking worse prognosis (P = 0.004 and 0.032 in two independent cohorts). Evolutionary analysis of initial-recurrent glioma pairs and single-cell study of a multi-centric glioblastoma reveals remarkable association between elevated TAMo and glioma mesenchymal transformation. Further analysis identifies FOSL2 as a master regulator of TAMo. The roles of FOSL2-EREG/AREG-EGFR signaling axis in promoting glioma invasion were verified experimentally. Collectively, we have identified TAMo in tumor microenvironment and revealed its driving role in activating EGFR signaling to shape glioma evolution.
