CD29 identifies IFN-γ–producing human CD8+ T cells with an increased cytotoxic potential

ABSTRACT: Cytotoxic CD8+ T cells can effectively kill target cells by producing cytokines, chemokines, and granzymes. Expression of these effector molecules is however highly divergent, and tools that identify and preselect CD8+ T cells with a cytotoxic expression profile are lacking. Human CD8+ T cells can be divided into IFN-γ– and IL-2–producing cells. Unbiased transcriptomics and proteomics analysis on cytokine-producing fixed CD8+ T cells revealed that IL-2+ cells produce helper cytokines, and that IFN-γ+ cells produce cytotoxic molecules. IFN-γ+ T cells expressed the surface marker CD29 already prior to stimulation. CD29 also marked T cells with cytotoxic gene expression from different tissues in single-cell RNA-sequencing data. Notably, CD29+ T cells maintained the cytotoxic phenotype during cell culture, suggesting a stable phenotype. Preselecting CD29-expressing MART1 TCR-engineered T cells potentiated the killing of target cells. We therefore propose that CD29 expression can help evaluate and select for potent therapeutic T cell products.

Identification of different human CD8 T cell subsets by superior cytotoxicity in human T cells

Project description:Cytotoxic CD8+ T cells can effectively kill target cells by producing cytokines, chemokines and granzymes. Expression of these effector molecules is however highly divergent, and tools that identify and pre-select potent killer cells are lacking. Human CD8+ T cells can be divided into IFNGand IL-2 producing cells. Unbiased RNA-sequencing and proteomics analysis on cytokine-producing fixed CD8+ T cells revealed that IL-2+ T cells produce helper cytokines, and that IFNG+ T cells produce cytotoxic molecules. IFNG+ cytotoxic T cells expressed the surface marker CD29 already prior to stimulation. CD29 also marked T cells with cytotoxic gene expression from different tissues in single-cell RNA-sequencing data. Notably, the cytotoxic features of CD29+ T cells were maintained during cell culture, suggesting a stable phenotype. Pre-selecting CD29-expressing MART1 TCR-engineered T cells potentiated the killing of target cells. We therefore propose that selecting for CD29+ T cells could boost the anti-tumoral activity of T cell therapeutics.

Gene expression profiles of human effector CD8+ T cell subsets

Project description:Effector CD8+ T cells are believed to be terminally differentiated cells having cytotoxic activity and the ability to produce effector cytokines such as INF-γ and TNF-α. We investigated the difference between CXCR1+ and CXCR1- subsets of human effector CD27-CD28-CD8+ T cells. Both subsets similarly expressed cytolytic molecules and exerted substantial cytolytic activity, whereas only the CXCR1- subset had IL-2 productivity and self-proliferative activity and was more resistant to cell death than the CXCR1+ subset. These differences were explained by the specific up-regulation of CAMK4, SPRY2, and IL-7R in the CXCR1- subset and that of pro-apoptotic DAPK1 in the CXCR1+ subset. The IL-2 producers were more frequently found in the IL-7R+ subset of the CXCR1- effector CD8+ T cells than in the IL-7R- subset. IL-7/IL-7R signaling promoted cell survival only in the CXCR1- subset. The present study has highlighted a novel subset of effector CD8+ T cells producing IL-2 and suggests the importance of this subset in the homeostasis of effector CD8+ T cells.

Gene expression profiles of human CD8+ T cells: IL-12 and IFN-a polarized in vitro stimulated and ex vivo sorted CCR7hi and CXCR3hi populations

Project description:CD8+ cytotoxic T lymphocytes (CTLs) play a major role in defense against intracellular pathogens, and their functions are specified by antigen recognition and innate cytokines. While effector CTLs eliminate the infection, a small population of memory cells are retained that yields more rapid and robust response upon re-infection. Antigen presenting cells secrete an array of innate cytokines including IL-12 and IFN-α after recognition of pathogens. Both IL-12 and IFN-α have been shown to act as the third signal regulating the development of CTLs. We have shown that these two cytokines have a non-redundant effect in generation of human effector CTL. IL-12 alone is sufficient for effector CTL genesis marked by IFN-γ and TNF-α production, as well as increased cytolytic activity. Even in the presence of IFN-α, IL-12 programs CTLs that express the chemokine receptor CXCR3 and effector cytokines. Using microarray analysis we have investigated how IL-12 and IFN-α differentially regulate the genetic programming pathways that give rise to effector CTLs among multiple human donors. We have also analyzed the gene expression patterns of cells sorted from healthy human peripheral blood that display surface markers of effector memory CTL (designated as ex vivo) samples. 5 healthy human donor samples were used for the in vitro cultures. For each donor the CFSE labeled cells (CD8+CD45RA+) were cultured in the presence of neutralized, IL-12, IFN-a, and IL-12+IFN-a conditions and plate-bound anti-CD3+anti-CD28 for 3.5 days. Total RNA from CFSEhi (Undiv) and CFSElo (Div) sorted cells were used for Illumina Bead Array. 4 healthy human donor samples were used for the ex vivo samples. Total RNA was collected from FACS sorted CD8+CCR7hiCXCR3lo and CD8+CCR7loCXCR3hi cells without any stimulation.

T-bet-depended but IFN-gamma-independent genes in GVHD

Project description:Given T-bet is a master regulator for Th1 differentiation that produce IFN-gamma, underlining mechanisms accounted for the distinct GVHD outcomes caused by T-bet- versus IFN-gamma-deficient donor T cells are unclear. We hypothesize that GVHD is regulated by T-bet-dependent but IFN-gamma-independent molecules. To identify these molecules, we isolated donor T cells from spleen cells of the recipients that were transplanted with WT, T-bet-/- or IFN-gamma-/- CD4 T cells for 7 days. The gene profile of isolated T cells was measured by microarray analysis using GeneChip Mouse Genome 430 2.0 arrays (Affymetrix) according to the manufacturerM-^Rs instructions. Array images were analyzed and processed by robust multi-array average (RMA) procedure.

Gene expression profiles of human effector CD8+ T cell subsets

Project description:Effector CD8+ T cells are believed to be terminally differentiated cells having cytotoxic activity and the ability to produce effector cytokines such as INF-M-NM-3 and TNF-M-NM-1. We investigated the difference between CXCR1+ and CXCR1- subsets of human effector CD27-CD28-CD8+ T cells. Both subsets similarly expressed cytolytic molecules and exerted substantial cytolytic activity, whereas only the CXCR1- subset had IL-2 productivity and self-proliferative activity and was more resistant to cell death than the CXCR1+ subset. These differences were explained by the specific up-regulation of CAMK4, SPRY2, and IL-7R in the CXCR1- subset and that of pro-apoptotic DAPK1 in the CXCR1+ subset. The IL-2 producers were more frequently found in the IL-7R+ subset of the CXCR1- effector CD8+ T cells than in the IL-7R- subset. IL-7/IL-7R signaling promoted cell survival only in the CXCR1- subset. The present study has highlighted a novel subset of effector CD8+ T cells producing IL-2 and suggests the importance of this subset in the homeostasis of effector CD8+ T cells. To find the genes that potentially cause the difference in IL-2 productivity and cell survival between the CXCR1+ and CXCR1- human effector CD8+ T cell subsets, we performed microarray gene expression analysis. We highly purified each CD3+CD8+ subset for this analysis (> 95.3%) from 5 healthy individuals, and then compared the gene expression profiles of each subset.

IFN? expression is restricted to a subpopulation of splenic pDCs exhibiting a specific immune modulatory transcriptome signature

Project description:Type I IFNs are critical in initiating protective antiviral immune responses and plasmacytoid DCs (pDCs) represent a major source of these cytokines. Here we show that only few pDCs are capable to produce IFN? after virus infection or CpG stimulation. Utilizing IFN?/YFP reporter mice, we identify these IFN?-producing cells in the spleen as a CCR9+CD9- pDC subset exclusively localized within the T/B cell zones. IFN?-producing pDCs exhibit a distinct transcriptome profile with higher expression of genes encoding cytokines and chemokines, facilitating T cell recruitment and activation. These distinctive characteristics of IFN?-producing pDCs are independent of the type I IFN receptor mediated feedback loop. Furthermore, IFN?-producing pDCs exhibit enhanced CCR7-dependent migratory properties in vitro and in a peritoneal inflammation model they effectively recruit T cells in vivo. We define “professional type I IFN-producing cells” as a distinct subset of pDCs specialized in coordinating cellular immune responses. IFN? associated gene expression in ex vivo sorted IFN?/YFPpos vs. IFN?/YFPneg splenic pDCs was measured at 6 hr after i.v. injection of CpG 1668 complexed to DOTAP. Two independent experiments were performed using pooled samples of at least 12 mice per experiment.

The effector program of human CD8 T cells can support tissue remodeling abilities.

Project description:This SuperSeries is composed of the SubSeries listed below. Abstract Paper: CD8 T lymphocytes are classically viewed as cytotoxic T cells. Whether human CD8 T cells can, in parallel, induce a tissue regeneration program is poorly understood. Here, antigen-specific assay systems revealed that human CD8 T cells not only mediated cytotoxicity, but also promoted tissue remodeling. Activated CD8 T cells could produce the epidermal growth factor receptor (EGFR)-ligand amphiregulin (AREG) and sensitize epithelial cells for enhanced regeneration potential. Blocking the EGFR or the effector cytokines IFN-γ and TNF could inhibit tissue remodeling. This regenerative program enhanced tumor spheroid and stem-cell-mediated organoid growth. Using single-cell gene expression analysis, we identified an AREG+, tissue-resident CD8 T-cell population in healthy donor skin and adipose tissue with a strong TCR clonal relation to blood PD1+TIGIT+ CD8 T cells with tissue remodeling abilities. These findings may help to understand the complex CD8 biology in tumors and could become relevant for the design of therapeutic T-cell products.

IFNg-producing Tfh cells control the differentiation of lung resident memory B cells

Project description:T follicular helper (Tfh) cells are a specific subset of CD4 T cells that localize in the B cell follicle and are essential for the Germinal Center (GC) response. Under polarizing environments, Tfh cells produce IFN-g. Beyond promoting class switching, the role played by IFN-g-producing Tfh cells remains largely unexplored. Using an influenza infection model, we show here that interactions with IFN-γ producing Tfh cells during the peak of the response skew the GC B cell response towards the memory differentiation pathway. Consequently, lung-memory B cells fail to differentiate without IFN-γ producing Tfh cells. Collectively, our results support a model in which temporary changes in cytokine production by Tfh cells dynamically control the outcome of the GC response.
