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

Project description:Th17 cells secrete IL-17A, IL-17F, IL-21, and IL-22 cytokines that are critical in mediating inflammation and protecting the host from microorganisms infection. The basic leucine zipper transcription factor ATF-like (Batf) contributes to the transcriptional programming of multiple effector T cells, and is required for Th17 cell development. Here, we have interrogated mechanisms by which Batf promotes and stabilizes Th17 cell phenotype. We have shown that in vitro differentiated Th17 cells have increased expression of Th1 and Treg signature genes in the absence of Batf. In addition, Citrobacter rodentium infected Batf-deficient (Batf KO) mice fail to clear the infection, and that is correlated with diminished IL-17A and IL-22 cytokine production and increased Foxp3 and Ifng expression compared to WT mice. We find that Batf sustains Th17 phenotype in long-term culture conditions by suppressing Th1- and Treg-specific gene expression. Mechanistically, we reveal that Batf negatively regulates IL-2-STAT5 signaling and modulates STAT5 binding at the Ifng and Foxp3 gene loci thus suppressing Th1-Treg phenotype in Th17 cell development. Inhibition of STAT5 DNA binding activity in Batf KO Th17 cells was able to repress Ifng and Foxp3 expression compared to control-treated cells. Moreover, STAT5 cooperates with transcription factors Ets1 and Runx1 to mediate epigenetic modification and regulate gene expression. Thus, our study has revealed an essential function of Batf in modulating the IL-2-STAT5 signaling to promote and stabilize Th17 cell development.

Project description:Metabolism plays an essential role in shaping Th cell responses including the production of pro-inflammatory cytokines. However, its effect on the production of the anti-inflammatory cytokine IL-10 has not been investigated. We show here that the glucose analogue 2-deoxyglucose (2DG) specifically inhibited Th1 and Th2 cell differentiation and accompanying IL-10 production. In contrast, 2DG promoted IL-17A production by Th17 cells, even in the presence of IL-2 known to limit Th17 differentiation, whilst simultaneously also abrogating the production of IL-10. Rather than inhibiting glycolysis, 2DG was found to act through the inhibition of glycosylation, itself critical for IL-2Ra surface expression and downstream signaling, explaining the reciprocal effect of 2DG on the Th1 and Th2 versus Th17 differentiation. The essential role of IL-2 for IL-10 production by Th17 cells was confirmed by adding IL-2 or anti-IL-2, neither of which made the cells more pathogenic. The molecular mechanism of the IL-2 driven Th17 IL-10 production may be attributed to the transcription factor c-Maf, whose expression was significantly upregulated in the presence of IL-2 signaling. The overall RNA signature of sorted IL-10+ T cells driven by IL-2, be it IL-17A+ or IL-17A-, was dominated by protein synthesis whereas that of their IL-10- counterparts by cell cycle associated processes suggesting that IL-10 secreting Th17 cells trade off self-renewal for secretory capacity. Our study thus reveals a previously unappreciated, anti-inflammatory role for IL-2 in Th17 cell production of IL-10 and identifies a novel mechanism to limit Th17 pathogenicity.

Project description:To improve our understanding of lncRNA expression in T cells, we used whole genome sequencing (RNA-seq) to identify lncRNAs expressed in human T cells and those selectively expressed in T cells differentiated under TH1, TH2, or TH17 polarizing conditions. The majority of these lineage-specific lncRNAs are co-expressed with lineage-specific protein-coding genes. These lncRNAs are predominantly intragenic with co-expressed protein-coding genes and are transcribed in sense and antisense orientations with approximately equal frequencies. Further, genes encoding TH lineage specific mRNAs are not randomly distributed across the genome but are highly enriched in the genome in genomic regions also containing genes encoding TH lineage-specific lncRNAs. Our analyses also identify a cluster of antisense lncRNAs transcribed from the RAD50 locus that are selectively expressed under TH2 polarizing conditions and co-expressed with IL4, IL5 and IL13 genes. Depletion of these lncRNAs via selective siRNA treatment demonstrates the critical requirement of these lncRNAs for expression of the TH2 cytokines, IL-4, IL-5 and IL-13. Collectively, our analyses identify new lncRNAs expressed in a TH lineage specific manner and identify a critical role for a cluster of lncRNAs for expression of genes encoding TH2 cytokines. Human peripheral blood mononuclear cells (PBMC) were cultured under TH1, TH2, and TH17 polarizing conditions. TH1, TH2, and TH17 primary and effector cultures were isolated and poly(A)+ and total RNA sequencing performed.

Project description:IRF4 is critical for differentiation of various CD4+ effector T cells, such as T helper 1 (Th1), Th2, and Th17 subsets, through interaction with BATF-containing AP-1 heterodimers. A major BATF heterodimeric partner, JunB, regulates Th17 differentiation, but the role of JunB in other CD4+ effector T subsets is not fully understood. Here we demonstrate that JunB is essential for accumulation of Th1 and Th2 cells, as well as Th17 cells, both in vitro and in vivo. In mice immunized with lipopolysaccharide (LPS), papain, or complete Freund’s adjuvant (CFA), that induce predominantly Th1, Th2 and Th17 cells, respectively, accumulation of antigen-primed, Junb-deficient CD4+ T cells is significantly impaired. Loss of JunB decreases viability of cells activated under Th1-, Th2-, and Th17-polarizing conditions. RNA-sequencing (RNA-seq) and chromatin immunoprecipitation sequencing (ChIP-seq) reveal that JunB directly regulates expression of various genes that are commonly induced in priming of naïve CD4+ T cells, including a pro-apoptotic gene Bcl2l11 (encoding Bim), and genes that are specifically induced in Th1, Th2, and Th17 cells. Furthermore, JunB colocalizes with BATF and IRF4 at genomic regions for approximately half of JunB direct target genes. Taken together, JunB, in collaboration with BATF and IRF4, serves a critical function in differentiation of diverse CD4+ T cells by controlling common and lineage-specific gene expression.

Project description:The protease BACE1 is a major drug target for Alzheimer’s disease, but chronic BACE1 inhibition is associated with non-progressive worsening that may be caused by modulation of unknown physiological BACE1 substrates. To identify in vivo-relevant BACE1 substrates we applied pharmacoproteomics to non-human-primate cerebrospinal fluid (CSF) after acute treatment with BACE inhibitors. Besides SEZ6, the strongest, dose-dependent reduction was observed for the pro-inflammatory cytokine receptor gp130/IL6ST, which we establish as a new in vivo BACE1 substrate. Gp130 was also reduced in human CSF from a clinical trial with a BACE inhibitor and in plasma of BACE1-deficient mice. Mechanistically, we demonstrate that BACE1 directly cleaves gp130, thereby attenuating membrane-bound gp130 and increasing soluble gp130 abundance and controlling gp130 function in neuronal IL-6 signaling and neuronal survival upon growth-factor withdrawal. In conclusion, BACE1 is a new modulator of gp130 function. The BACE1-cleaved, soluble gp130 may serve as a pharmacodynamic BACE1 activity marker to reduce the occurrence of side effects of chronic BACE1 inhibition in humans.

Project description:Purpose: Recently discovered activating Interleukin-6 receptor subunit beta (IL6ST, encoding glycoprotein 130 (gp130)) mutations, as well as germline Signal transducer and activator of transcription 3 (STAT3) gain-of-function mutations are associated with multi-organ autoimmunity, severe morbidity, and adverse prognosis, resulting in an unmet medical need. Methods: To dissect crucial cellular subsets and disease biology involved in activated gp130 signaling, in this study we constitutively activated the gp130/JAK/STAT3 axis by means of a transgene, L-gp130, specifically targeted to T-cells. Results: Activating gp130 signaling in vivo resulted in fatal early-onset multi-organ autoimmunity, resembling numerous clinical features of human STAT3 gain-of-function disease. We observed strong T-cell activation and effector differentiation, accompanied by TH17 expansion and interferon-gamma production. Transcriptome profiling of murine CD4+ and CD8+ T-cells revealed commonly dysregulated genes and a STAT3 gain-of-function signature that was used to discriminate between STAT3 gain-of-function and healthy control patients. Conclusions: Hyperactive gp130/STAT3 signaling leads to strong TH17-mediated autoimmunity phenotypically resembling human STAT3 gain-of-function disease and identify TH17-cells as a key cellular subset for initiation and maintenance of autoimmunity
