Project description:Interleukin 23 (IL-23) triggers pathogenic features in pro-inflammatory, IL-17-secreting T cells (Th17 and Tγδ17) that play a key role in the development of inflammatory diseases. However, the IL-23 signaling cascade remains largely undefined. Here we used quantitative phosphoproteomics to characterize IL-23 signaling in primary murine Th17 cells. We quantified 6,888 phosphorylation sites in Th17 cells, and found 168 phosphorylations regulated upom IL-23 stimulation. IL-23 increased the phosphorylation of the myosin regulatory light chain (RLC), an actomyosin contractibility marker, in Th17 and Tγδ cells. IL-23-induced RLC phosphorylation required JAK2 and ROCK catalytic activity, and the study of the IL-23/ROCK axis revealed an unexpected role of IL-23 in the migration of Tγδ17 and Th17 cells. Moreover, pharmacological inhibition of ROCK reduced Tγδ17 recruitment to inflamed skin upon challenge with inflammatory agent Imiquimod. This work: i) provides new insights into phosphorylation networks that control Th17 cells, ii) widely expands the current knowledge on IL-23 signaling, and iii) contributes to the increasing list of immune cells subsets characterized by global phosphoproteomic approaches.

Project description:TGF-beta3 produced by developing Th17 cells induces highly pathogenic T cells that are functionally and molecularly distinct from TGF-beta1-induced Th17 cells. The microarray data represent a distinct molecular signature for pathogenic versus non-pathogenic Th17 cells. Total of seven groups with two to four samples per group from two independent experiments. The no cytokines group (Th0) was used as a control to normalize the data. 7 groups: B6: (IL-1beta, IL-6) B623: (IL-1beta, IL-6, IL-23) T16: (TGF-beta1, IL-6) T1623: (TGF-beta1, IL-6, IL-23) T36: (TGF-beta3, IL-6) T3623: (TGF-beta3, IL-6, IL-23) NOCYTO: no cytokines

Project description:IL-10 production by Th17 cells is critical for limiting autoimmunity and inflammatory responses. Gene array analysis on Stat6 and T-bet double deficient Th17 cells identified the Th2 transcription factor c-Maf to be synergistically up-regulated by IL-6 plus TGFbeta, and associated with Th17 IL-10 production. Both c-Maf and IL-10 induction during Th17 polarization depended on Stat3, but not Stat6 or Stat1, and mechanistically differed from IL-10 regulation by Th2 or IL-27 signals. TGFbeta was also synergistic with IL-27 to induce c-Maf, and induced Stat1 independent IL-10 expression in contrast to IL-27 alone. Retroviral transduction of c-Maf was able to induce IL-10 expression in Stat6 deficient CD4 and CD8 T cells, and c-Maf directly transactivated IL-10 gene expression through binding to a MARE motif in the IL-10 promoter. Together, these data reveal a novel role for c-Maf in regulating T effector development, and suggest that TGFbeta may antagonize Th17 immunity by IL-10 production through c-Maf induction. Our recent studies showed that IL-6 combined with TGFbeta differed from IL-6 combined with IL-23 for IL-10 production and pathogenic activities in CD4 T cells deficient in Stat6 and T-bet, despite similar IL-17 production. We performed gene array analysis on Stat6 and T-bet double deficient cells. We rationalized that by comparing gene expression in cells treated with IL-6 plus TGFbeta versus TGFbeta alone, we would be able to identify genes specific for standard Th17 polarization, and responsible for both IL-17 and IL-10 expression. By next comparing gene expression in cells treated with IL-6 plus TGFbeta versus IL-6 plus IL-23, we could eliminate molecules involved solely in IL-17 regulation, and obtain genes specifically responsible for IL-10 regulation.

Project description:We report that Tripartite motif-containing 33 (Trim33), a protein that was previously associated with TGF-beta signaling, determines the pathogenic function of Th17 cells. Trim33 deficiency in T cells resulted in resistance to an autoimmune disease model. Lack of Trim33 did not impact TGF-beta signaling in mediating Foxp3 gene expression but greatly reduced TGF-beta induction of IL-17 production during Th17 cell differentiation. Importantly, we found TGF-beta not only increased IL-17 but also suppressed IL-10 expression; absence of Trim33 or Smad2 but not Smad4 in T cells enhanced IL-10 expression. In a Smad2-dependent manner, Trim33 was recruited to Il17 and Il10 gene loci and was crucial in appropriate histone modification accompanying Th17 differentiation. Our study thus demonstrates that Trim33, a non-canonical branch of TGF-beta signaling, programs the pro-inflammatory function of Th17 differentiation by promoting IL-17 and suppressing IL-10 expression. As a critical switch of pathogenic versus regulatory phenotype of T cells, Trim33 may be targeted in treating human autoimmune diseases.

Project description:We next sought to identify the transcriptional program that differentiates IL-9+Th2 cells from “conventional” Th2 cells. To this end, we selected representative Th1, Th17, Th2, and IL-9+Th2 clones (Figure 5A) and determined their transcriptome in the resting state and at different time points after activation using RNAseq. Peripheral Blood Mononuclear Cells (PBMC) were isolated by Ficoll-Plaque Plus (GE Healthcare, UK) density gradient centrifugation. Human CD4+ T cells were isolated from PBMC by EasySep positive selection kit (Stemcell Technologies) according to manufacturer’s instruction. Positively selected CD4+ T cells were washed with PBS and stained for subsequent Th cell subset sorting. Memory Th cell subsets were sorted to over 90% purity according to their expression of chemokine receptors from CD45RA-CD25-CD8-CD3+ cells: Th1(CXCR3+CCR8-CCR6-CCR4-), Th2 (CXCR3-CCR8-CCR6-CCR4+), Th17 (CXCR3-CCR8-CCR6+CCR4+), Th9 (CXCR3-CCR8+CCR6-CCR4+). Single cell Th subset clones were directly sorted into 96well plate according to their expression of chemokine receptors (see above). Single cell clones were expanded and maintained by periodic restimulation with PHA (phytohaemaglutinine, 1 µg/ml, Sigma-Chemicals) and irradiated allogenic feeder cells (5x104/well) in culture medium. T cells were polyclonally activated using beads coated with antibodies against CD3, CD2, and CD28 (T cell/bead = 2:1, human T cell activation/expansion Kit, Miltenyi). Cell cultures were sampled before activation (time 0h) and 2, 4, 6, 9, 12, 24, and 48 hours after activation.

Project description:Interleukin 17 (IL-17) producing T helper 17 (Th17) cells are critical drivers of pathogenesis in a variety of autoimmune and inflammatory diseases. Strategies to mitigate excessive Th17 response thus remain an attractive target for immunotherapies. Here we report that Cancerous Inhibitor of Protein Phosphatase 2A (CIP2A) regulates IL-17 production by Th17 cells in human and mouse. Using CIP2A knock-out (KO) mice and siRNA-mediated CIP2A silencing in human primary CD4+ T cells, we demonstrated that CIP2A silencing results in a significant increase in IL-17 production. Interestingly, CIP2A deficient Th17 cells were characterized by increased strength and duration of STAT3 (Y705) phosphorylation. Genome-wide gene expression profile as well as the p-STAT3 (Y705) interactome of CIP2A deficient Th17 cells identified that CIP2A regulates the strength of the interaction between Acylglycerol kinase (AGK) and STAT3, and thereby, modulates STAT3 phosphorylation as well as expression of IL-17 in Th17 cells. Our results uncover the physiological function of CIP2A in Th17 cells and provides new opportunities for therapeutic intervention in Th17 cell mediated diseases.

Project description:Th17 cells are highly proinflammatory cells that are critical for clearing extracellular pathogens like fungal infections and for induction of multiple autoimmune diseases1. IL-23 plays a critical role in stabilizing and endowing Th17 cells with pathogenic effector functions2. Previous studies have shown that IL-23 signaling reinforces the Th17 phenotype by increasing expression of IL-23 receptor (IL-23R)3. However, the precise molecular mechanism by which IL-23 sustains the Th17 response and induces pathogenic effector functions has not been elucidated. Here, we used unbiased transcriptional profiling of developing Th17 cells to construct a model of their signaling network and identify major nodes that regulate Th17 development. We identified serum glucocorticoid kinase-1 (SGK1), as an essential node downstream of IL-23 signaling, critical for regulating IL-23R expression and for stabilizing the Th17 cell phenotype by deactivation of Foxo1, a direct repressor of IL-23R expression. A serine-threonine kinase homologous to AKT4, SGK1 has been associated with cell cycle and apoptosis, and has been shown to govern Na+ transport and homeostasis5, 6 7, 8. We here show that a modest increase in salt (NaCl) concentration induces SGK1 expression, promotes IL-23R expression and enhances Th17 cell differentiation in vitro and in vivo, ultimately accelerating the development of autoimmunity. The loss of SGK1 resulted in abrogation of Na+-mediated Th17 differentiation in an IL-23-dependent manner. These data indicate that SGK1 is a critical regulator for the induction of pathogenic Th17 cells and provides a molecular insight by which an environmental factor such as a high salt diet could trigger Th17 development and promote tissue inflammation.

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.
