Combinatorial flexibility of cytokine during Human T helper cells differentiation

Project description:Transcriptional analysis of human T cells differentiated in 4 T Helper context ( Th0, Th1, Th2 and Th17) in the presence or not of Interferon alpha We analyzed the transcriptomic profiles of 4 human naives T cells diferentiated in Th0, Th1, Th2 and Th17 in the presence or not of Interferon Alpha. Microarray analyses were performed in 2 time points : 1/ after Day 5 of polarization (= Day5); 2/ after Day 5+ four hours of re-stimulation (=Day 5+ 4H restim) in 3 different donors.

Project Title: Proteome analysis of CD4+ T cell subsets

Project description:Functionally distinct CD4+ helper T (Th) cell subsets, such as Th1, Th2, Th17, and regulatory T cells (Treg), play a pivotal role in the host-defense against pathogen invasion and the pathogenesis of inflammatory disorders. In this project, DIA-MS-based proteome analysis was performed on naïve CD4+ T, Th0, Th1, Th2, Th17 and iTreg cells using Q Exactive HF-X (Thermo Fisher Scientific) to search for proteins that differ among the cell subsets.

Cytokine receptor modulation by interleukin-2 broadly regulates T helper cell lineage differentiation

Project description:T helper (Th) cells control host defense to pathogens. IL 12R expression is required for Th1, IL-4RM-NM-1 for Th2, and IL-6RM-NM-1/gp130 for Th17 differentiation to allow responsiveness to IL-12, IL-4, and IL-6, respectively. IL-2 via STAT5 controls Th2 differentiation by regulating the Th2 cytokine gene cluster and Il4ra expression. Here we show that IL-2 regulates Th1 differentiation, inducing STAT5-dependent IL-12RM-NM-22 and T-bet expression, with impaired human Th1 differentiation when IL-2 was blocked. Th1 differentiation was also impaired in mouse Il2-/- T cells but restored by IL-12RM-NM-22 expression. Consistent with IL-2M-bM-^@M-^Ys inhibition of Th17 differentiation, IL-2 decreased Il6ra and Il6st/gp130 expression, and Il6st augmented Th17 differentiation even when IL-2 was present. Thus, IL-2 influences T-cell differentiation by modulating cytokine receptor expression to help specify/maintain differentiated states. Genome-wide mapping of STAT1,STAT4,STAT5A,STAT5B binding to their target genes in Th1 or human CD4+ cells was conducted

Cytokine receptor modulation by interleukin-2 broadly regulates T helper cell lineage differentiation

Project description:T helper (Th) cells control host defense to pathogens. IL 12R expression is required for Th1, IL-4Rα for Th2, and IL-6Rα/gp130 for Th17 differentiation to allow responsiveness to IL-12, IL-4, and IL-6, respectively. IL-2 via STAT5 controls Th2 differentiation by regulating the Th2 cytokine gene cluster and Il4ra expression. Here we show that IL-2 regulates Th1 differentiation, inducing STAT5-dependent IL-12Rβ2 and T-bet expression, with impaired human Th1 differentiation when IL-2 was blocked. Th1 differentiation was also impaired in mouse Il2-/- T cells but restored by IL-12Rβ2 expression. Consistent with IL-2’s inhibition of Th17 differentiation, IL-2 decreased Il6ra and Il6st/gp130 expression, and Il6st augmented Th17 differentiation even when IL-2 was present. Thus, IL-2 influences T-cell differentiation by modulating cytokine receptor expression to help specify/maintain differentiated states.

Gene expression data from polarized T helper cells isolated from mice with opticospinal (OSE) experimental autoimmune encephalomyelitis (EAE)

Project description:T cells from the spleen of a mixed-gender pool of four double-transgenic 2D2 (TCRMOG) x IgHMOG mice (OSE) mice, which spontaneously develop experimental autoimmune encephalomyelitis (EAE), were used to derive TH1- and TH17-polarized cells, as described in https://doi.org/10.1371/journal.pone.0015531. Here, expression was compared, first, between TH1 and naïve TH0 and, second, between TH17 and naïve TH0 cells.

Functional and epigenetic studies reveal multistep differentiation and plasticity of in vitro and in vivo follicular T helper cells

Project description:Follicular T helper cells (Tfh) provide critical help to B cells for germinal center (GC) formation. Mutations affecting SLAM-associated Protein (SAP) prevent GC formation due to defective T-B cell interactions, yet effects on Tfh cell differentiation remain unclear. We describe the in vitro differentiation of functionally-competent “Tfh-like” cells that expressed Interleukin-21, Tfh markers, and Bcl6, and rescued GC formation in SAP-deficient hosts better than other T helper (Th) cells. SAP-deficient Tfh-like cells appeared virtually indistinguishable from wildtype, yet failed to support GCs in vivo. Interestingly, both Tfh-like and in vivo-derived Tfh cells could produce effector cytokines in response to polarizing conditions. Moreover, Th1, Th2 and Th17 cells could be reprogrammed to obtain Tfh characteristics. ChIP-Seq analyses revealed positive epigenetic markings on Tbx21, Gata3 and Rorc in Tfh-like and ex vivo Tfh cells, and Bcl6 in other Th cell populations, supporting the concept of plasticity between Tfh and other Th cells. Epigenetic modifications were evaluated in ChIP-Seq studies by profiling histone H3K4 and H3K27 trimethylation marks between Th1, Th2, Th17, Tfh-like, and CXCR5+PD-1+ sorted Tfh-like in vitro generated T helper cell populations and ex vivo derived Tfh cells.

Klf4 expression in conventional dendritic cells is required for T helper 2 cell responses

Project description:Subset-specific and progenitor gene expression analysis of Klf4+/+ and Klf4-/- DCs. The two major lineages of classical dendritic cells (cDCs) express and require either IRF8 or IRF4 transcription factors for their development and function. IRF8-dependent cDCs promote anti-viral and T-helper 1 (Th1) cell responses, whereas IRF4-expressing cDCs have been implicated in controlling both Th2 and Th17 cell responses. Here, we have provided evidence that Kruppel-like factor 4 (Klf4) is required in IRF4-expressing cDCs to promote Th2 but not Th17 cell responses in vivo. Conditional Klf4 deletion within cDCs impaired Th2 cell responses during Schistosoma mansoni infection, Schistosoma egg antigen (SEA) immunization, and house dust mite challenge (HDM), without affecting cytotoxic T lymphocyte (CTL), Th1 and Th17 cell responses to herpes simplex virus, Toxoplasma gondii and Citrobacter rodentium infections. Further, Klf4 deletion reduced IRF4 expression in pre-cDCs and resulted in selective loss of IRF4-expressing cDCs subsets in several tissues. These results indicate that Klf4 guides a transcriptional program promoting IRF4-expressing cDCs heterogeneity. Bone marrow progenitors and skin draining LN subsets were harvested from 4 Klf4fl/fl cre negative or Vav1-icre mice and were sorted to >95% purity on the FACS Aria 3.

Targeted next generation sequencing of 589 genes identifies complementary responses in t-helper-like T regulatory cells

Project description:Regulatory T-cells (Tregs) play a pivotal role in maintaining peripheral immunological tolerance, by preventing autoimmunity and chronic inflammation. However, they can also play a parallel role in the promotion of antitumor responses. Tregs can be classified as T helper (Th)-like Tregs that phenotypically resemble Th1/Th2/Th17/TH1-TH17 lineages based upon the expression of specific chemokine receptors and transcription factors. The distribution of these Treg subsets can provide mechanistic insights into disease processes, therefore we sought to characterise their immune transcriptome. Targeted RNA sequencing revealed that circulating Th2-like Tregs displayed higher viability and activation as well as suggesting specific disease pathways associated to sifferent T reg subtypes.
