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. On a cellular level, strong T-cell activation and effector differentiation, accompanied by TH17 expansion and interferon-gamma production was observed. Transcriptome profiling of murine CD4+ and CD8+ T-cells of Lgp and Stat3C mice revealed commonly dysregulated genes and a gene signature that allowed for discrimination between STAT3 gain-of-function patients and healthy controls. In summary, we demonstrate that hyperactive gp130/STAT3 signaling leads to TH17-driven autoimmunity, phenotypically resembling human STAT3 gain-of-function disease. 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

Methods: To decipher the crucial cellular subsets and disease biology associated with STAT3 gain-of-function mutations, we examined the gene expression profile of STAT3 gain-of-function and loss-of-function mutations in unstimulated, IL10- or IL21-stimulated CD4 T cells and compared them to healthy donor 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.

Project description:RORγt is well recognized as the lineage defining transcription factor for TH17 cell development. However, the cell-intrinsic mechanisms that negatively regulate TH17 cell development and autoimmunity remain poorly understood. Here we demonstrate that the transcriptional repressor REV-ERBa is exclusively expressed in TH17 cells, competes with RORγt for their shared DNA consensus sequence, and negatively regulates TH17 cell development via repression of genes traditionally characterized as RORγt-dependent, including Il17a. Deletion of REV-ERBa enhanced TH17-mediated pro-inflammatory cytokine expression, exacerbating experimental autoimmune encephalomyelitis (EAE) and colitis. Treatment with REV-ERB-specific synthetic ligands, which have similar phenotypic properties as RORγ modulators, suppressed TH17 cell development, was effective in colitis intervention studies, and significantly decreased the onset, severity, and relapse rate in several models of EAE without affecting thymic cellularity. Our results establish that REV-ERBa negatively regulates pro-inflammatory TH17 responses in vivo and identifies the REV-ERBs as potential targets for the treatment of TH17-mediated autoimmune diseases.

Project description:Th17 cells are a heterogeneous population that is critical for tissue homeostasis and inflammation during clearance of infections and autoimmunity. Despite substantial efforts distinguishing homeostatic and inflammatory roles of Th17 cells, the mechanism underlying the divergent functions of inflammatory Th17 cells is poorly understood. In this study, we show that the inflammatory Th17 engaged in autoimmune colitis and those involved in infection-induced colitis are two distinguishable populations illustrated by their distinct responses to a pharmacological molecule, clofazimine (CLF). Distinct from existing Th17 inhibitors, CLF selectively inhibits pro-autoimmune Th17 cells while preserving the functional state of infection-elicited Th17 cells through restricting Aldh1l2expression. Using bulk RNA sequencing, we explored transcriptional response to CLF on in vitro differentiated inflammatory and homeostatic Th17 cells. Notably, we identified a unique suppression in the transcription of signature inflammatory genes in Th17 cells with a marginal effect on those elicited by infection.

Project description:To analyze the effect of Glycoprotein 130 in small diameter sensory neurons, dorsal root ganglia (DRG) of conditional SNS-gp130-/- and control (gp130fl/fl) mice were collected and mRNA expression profiles were compared between the two groups. DRG samples of two littermate mice were always pooled and a total of 10 gp130fl/fl and 10 SNS-gp130-/- mice were divided into 5 groups per genotype. Expression of transcripts were analyzed using the Applied Biosystems microarray platform AB1700 (Mouse Genome Survey Microarray V2.0).

Using single-cell RNA sequencing, we explored inflammatory Th17 transcriptional response to CLF from the colonic tissue of mice during autoimmune colitis and Citrobacter rodentiuminfection using Rorc gfp/+ reportor mice. Notably, we identified a unique suppression in the transcription of signature inflammatory genes in Th17 cells from autoimmune colitis with a marginal effect on those elicited by infection. Additionally, we illustrate with these data that the transcriptionally programming of pro-autoimmune Th17 cells are, indeed, unique compared to infection-elicited Th17 cells. Finally, we analyzed the impact of CLF on human inflammatory Th17 cells from the inflammed colon of a patient with IBD.
