Project description:Defective interleukin-6 (IL-6) signaling has been associated with Th2 bias and elevated IgE. However, the underlying mechanism by which IL-6 may prevent the development of Th2-driven diseases remains unknown. Using a model of house-dust-mite (HDM)-induced Th2 differentiation and allergic airway inflammation, we show here that IL-6 signaling in allergen-specific T cells was required to prevent Th2 development and subsequent IgE response and allergic inflammation. Th2 cell lineage commitment required strong sustained IL-2 signaling. Importantly, we found that IL-6 turned off IL-2 signaling during early T cell activation and thus inhibited Th2 cell priming. Mechanistically, we found that IL-6-driven inhibition of IL-2 signaling in responding T cells was mediated by upregulation of suppressor of cytokine signaling 3 (SOCS3). Therapeutically, this mechanism can be mimicked by JAK1 inhibition. Collectively, our results identify an unrecognized mechanism that prevents the development of unwanted Th2 cell responses and associated diseases and outline potential preventive interventions.

Project description:Effects of SOCS3 on the transcriptional response of bone marrow-derived macrophages to IL-6. Fetal liver cells from SOCS3+/+ or SOCS3-/- embryos were used to reconstitute recipient mice. Donor derived bone marrow from these mice was differentiated to macrophages. Macrophages were either unstimulated, or stimulated for 100 or 400 minutes with 10 ng/ml IL-6. Keywords = macrophage, SOCS3, IL-6, interferon

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:Th2 cells enable humoral immunity and host-defense to parasites. Whereas IL-4 drives Th2 differentiation and IL-2 is important later in this process by augmenting IL4 chromatin accessibility, we demonstrate that IL-2 serves an essential early role in regulating IL-4R? expression by inducing binding of Stat5a and Stat5b to the IL4ra locus, with sustained binding during Th2 differentiation. Although IL-4 induces IL-4R? expression, TCR-induced IL-4R? expression was unexpectedly normal in ILr-/- but profoundly diminished in IL2-/- T cells. Remarkably, enforced IL-4R? expression rescued Th2 differentiation in IL2-/- cells. These results reveal a novel function for IL-2, with IL-2 via Stat5 providing an early signal for IL4ra induction, thereby priming cells for Th2 differentiation and promoting/maintaining IL-4R? expression in Th2-committed cells. ChIP-seq experiments for Stat5a and Stat5b with an IgG control experiment for 8hr, 13hr and 2 rounds of Th2 differentiation.

Project description:Uncontrolled type 2 immunity by type 2 helper T (Th2) cells causes intractable allergic diseases; however, whether the interaction of CD4+ T cells shapes the pathophysiology of allergic diseases remains unclear. We identified a subset of Th2 cells that produced the serine proteases granzyme A and B early in differentiation. Granzymes cleave protease-activated receptor (Par)-1 and induce phosphorylation of p38 mitogen-activated protein kinase (MAPK), resulting in the enhanced production of IL-5 and IL-13 in both mouse and human Th2 cells. Ubiquitin-specific protease 7 (USP7) regulates IL-4-induced phosphorylation of STAT3, resulting in granzyme production during Th2 cell differentiation. Genetic deletion of Usp7 or Gzma and pharmacological blockade of granzyme B ameliorated allergic airway inflammation. Furthermore, PAR-1+ and granzyme+ Th2 cells were colocalized in nasal polyps from patients with eosinophilic chronic rhinosinusitis. Thus, the USP7-STAT3-granzymes-Par-1 pathway is a potential therapeutic target for intractable allergic diseases.
