Multiomic profiling of chronically activated CD4+ T cells identifies drivers of exhaustion and metabolic reprogramming

ABSTRACT: T-cell exhaustion occurs when T cells are chronically activated, usually in the context of cancer or chronic infection. Exhausted T cells lose effector functions, upregulate inhibitory receptors, and lose proliferation ability. Understanding the mechanisms of T-cell exhaustion is important as it has critical clinical applications, such as checkpoint blockade therapy. CD4+ T cells are understudied in the context of exhaustion, and no large-scale multiomic datasets containing proteomics, phosphoproteomics, or metabolomics exist. We therefor performed a multiomic experiment to profile this cell state using a time course analysis to also capture progression.

PD-L1 overexpression, SWI/SNF complex Deregulation and Profound Transcriptomic Changes Characterize Cancer-Dependent Exhaustion of Persistently Activated CD4+ T Cells

Project description:The growing tumor avoids recognition and destruction by immune system. During continuous stimulation of tumor infiltrating lymphocytes (TILs) by tumor, TILs become functionally exhausted. Thus, they become unable to kill tumor cells and to produce some cytokines, and lose their ability to proliferate. It collectively results in the immune escape of cancer cells. Here, we show that breast cancer cells expressing PD-L1 can accelerate exhaustion of persistently activated human effector CD4+ T cells, manifesting in high PD-1 and PD-L1 expression level on cell surface, decreased glucose metabolism genes, strong downregulation of SWI/SNF chromatin remodeling complex subunits and p21 cell cycle inhibitor upregulation. This results in inhibition of T cell proliferation and reduction of T cells number. The RNAseq analysis on exhausted CD4+ T cells indicated strong overexpression of IDO1 and genes encoding pro-inflammatory cytokines and chemokines. The PD-L1 overexpression was also observed in CD4+ T cells after co-cultivation with other cell line overexpressing PD-L1 that suggested the existence of general mechanism of CD4+ T cell exhaustion induced by cancer cells. The ChIP analysis on PD-L1 promoter region indicated that the strong BRM recruitment in control CD4+ T cells is replaced by BRG1 and EZH2 in CD4+ T cells strongly exhausted by cancer cells. These findings suggest that such epi-drugs as EZH2 inhibitors may be used as immunomodulators in cancer treatment.

Lymphopenia-induced T cell exhaustion in STING gain-of-function mouse model

Project description:STING gain-of-function (GOF) mutations lead to T cell lymphopenia, in the context of severe combined immunodeficiency (SCID) for STING GOF V154M mice. This T cell lymphopenia, which is of central origin, has been described as type I IFN independent and associated with dysfunctions of the rare mature T cells found in the periphery. To better describe the biological mechanisms of these dysfunctions, we performed a transcriptomic analysis by RNA-seq on sorted splenic CD4+ and CD8+ mature T cells from STING GOF mice. We highlighted an unexpected T cell exhaustion phenotype that could partly explain their dysfunctions. Acquired very early in life, but only once the peripheral environment is reached, the phenotype appeared to depend neither on type I IFNs, nor on the intrinsic activation of STING in T or stromal cells. Mechanistically, the few mature T cells reaching the periphery seem to be rapidly impacted by the lymphopenic environment through increased antigenic and IL-7 stimulations that could lead to their exhaustion. By using STING GOF long term-hematopoietic stem cells (LT-HSC) transplantations with supportive wild-type bone marrow (BM) cells, we prevented the T cell exhaustion of STING GOF T cells in the resulting non lymphopenic context. With the support of lymphopenic RAG1 hypomorphic mice developing the phenotype, our data uncover a lymphopenia-mediated T cell exhaustion mechanism in STING GOF mice, for which a synergistic effect of the mutation is also envisaged.

A Multi-Omic Analysis of Human Naive CD4 T cells

Project description:Technological advances in genomics, epigenomics, transcriptomics and proteomics have enabled massively parallel measurements across thousands of genes and gene products. Such high-throughput technologies have been extensively used to carry out genome-wide studies particularly in the context of diseases. Nevertheless, a unified analysis of the genome, epigenome, transcriptome, and proteome of a single mammalian cell type to obtain a coherent view of the complex interplay between omes has not yet been undertaken. Here, we report the first multi-omic analysis of human primary naïve CD4+ T cells, revealing hundreds of unannotated mRNA transcripts, miRNAs, pseudogenes, and noncoding RNAs. Additionally, we carried out a comparative analysis of naïve CD4+ T cells with primary resting memory CD4+ T cells, which have provided novel insights into T cell biology. Overall, our data will serve as a baseline reference of a single pure population of cells for future systems level analysis of other defined cell populations.

Generation and purification of Th1 and Th2 effector and memory CD4+ T cells

Project description:NaÃ¯ve CD4+ T cells were isolated from spleen of AND TcR transgenic/green fluorescence protein (GFP) transgenic mice (Kaye et al., Nature 1989;341:746, Wright et al, Blood 2001;97:2278) that recognize a peptide of pigeon cytochrome C in the context of I-Ek and express CD44lo, CD62Lhi, CD45RBhi, and CD25-. After 4 days in vitro stimulation with antigen presenting cells (APC) under either Th1 or Th2 condition, naÃ¯ve cells become Th1 or Th2 effector cells expressing CD44hi, CD62L lo, CD45RBhi, and CD25+. Additional 3 days culture in the absence of APC, those effector cells become rested expressing a phenotype similar to memory cells (CD44 hi, CD62L lo, CD45RB lo and CD25-). These rested effector cells were adaptively transferred into thymectomized, lethally irradiated, and T cell depleted bone marrow reconstituted mice and memory cells were isolated after 4-12 weeks by flow sort. Generation and purification of Th1 and Th2 effector and memory CD4+ T cells of 42 samples.

Single-cell sequencing of tissue-resident CD4+ T cells that drive compartmentalized immunopathology in the CNS

Project description:In chronic inflammatory diseases of the central nervous system (CNS), immune cells persisting behind the blood-brain barrier are supposed to promulgate local tissue destruction. The drivers of such compartmentalized inflammation remain unclear, but tissue-resident memory T cells (TRM) represent a potentially important cellular player in this process

Expression data from human memory CD4 T-cells stimulated with autologous monocytes pulsed with HCMV

Project description:The present study reports an unbiased analysis of the genetic profile and regulation of NKG2D expressing CD4 T-cells.An Affymetrix microarray analysis was used to explore the genetic profile of NKG2D+ versus NKG2D- CD4 T-cells. The genetic profile was studied by single gene analysis and gene set enrichment analysis. I found that several immune regulatory receptors was regulated differently in NKG2D+ versus NKG2D- CD4 T-cells. Futhermore, I found that NKG2D+ CD4 T-cells display a genetic profile of cytotoxic T-cells. The gene set enrichment analysis revealed a change in 19 processes, including ARF GTPase activator activity; RNA splicing; Signal transduction; Interspecies interaction between organisms; Regulation of ARF GTPase activity; Cell motility; Mitosis; Cell cycle; Anaphase-promoting complex-dependent proteasomal ubiquitin-dependent protein catabolic process; Induction of apoptosis by extracellular signals; Negative regulation of apoptosis; mRNA export from nucleus; Positive regulation of ubiquitin-protein ligase activity involved in mitotic cell cycle; Cell division; Protein polymerization; Spliceosome assembly; Microtubule-based movement; Immune response; mRNA processing. Human CD4 T-cells were isolated from buffy coat by anti-CD4 conjugated magnetic beads. Memory CD4 T-cells were sorted, labeled with CFSE and stimulated with autologous monocytes pulsed with HCMV. HCMV stimulated CD4 T-cells were sorted as CFSE-NKG2D+ or CFSE-NKG2D- and processed for microarray analysis.

DNA methylation profiling of primary human CD4+T-cell memory subsets

Project description:Differentiation of CD4+T-cells into effector subsets is a critical component of the adaptive immune system and an incorrect response can lead to autoimmunity or immune deficiency. Cellular differentiation including T-cell differentiation is accompanied by large-scale epigenetic remodeling, including changes in DNA methylation at key regulators of T-cell differentiation. The TET family of enzymes were recently shown to be able to catalyse methylated cytosine (5mC) into 5-hydroxymethylcytosine (5hmC) enabling a pathway of active removal of DNA methylation. Here, we characterize 5hmC, 5mC and transcriptional dynamics during human CD4+T-cell polarisation in a time series approach and relate these changes to profiles in ex-vivo CD4+memory subsets. We observed large-scale remodelling during early CD4+T-cell differentiation which was predictive of subsequent changes during late time points, these changes were also related to disease associated regions which we show can act as functional regulatory elements. This dataset was designed to assess how DNA methylation differs between in-vivo derived CD4+memory T-cell subsets. DNA methylation was assessed in relationship to gene expression levels and changes (see data series), we observed anticorrelation between promoter DNA methylation levels and gene expression. This submission contains data from DNA methylation profiling of primary human CD4+T-cell memory subsets. This is part of a series, containing transcription and DNA methylation profiling of the same samples. See related experiments E-MTAB-4685, E-MTAB-4686, E-MTAB-4687, E-MTAB-4688

CXCR3+ Treg cells suppress Th1-immune responses through expression of the co-inhibitory receptors CD85k and Lag-3

Project description:CD4+Foxp3+ Treg cells are essential for maintaining self-tolerance and preventing excessive immune responses. In the context of Th1 immune responses, co-expression of the Th1 transcription factor T-bet with Foxp3 is essential for Treg cells to control Th1 responses. T-bet-dependent expression of CXCR3 directs Tregs to the site of inflammation, however, the suppressive mediators enabling effective control of Th1 responses at this site are unknown. In this study, we determined the signature of CXCR3+ Treg cells arising in Th1 settings and defined universal features of Treg cells in this context using multiple Th1-dominated models. Our analysis defined a set of Th1-specific co-inhibitory receptors that are specifically expressed in Treg cells during Th1 immune responses. Among these, we identified the novel co-inhibitory receptor CD85k as a functional mediator of the enhanced suppression of Th1 effector cells by CXCR3+ Treg cells.
