Satb1 directs the differentiation of TH17 cells through suppression of IL-2 expression [scMultiom ATAC/RNA-seq]

ABSTRACT: TH17 cells play an important role in host defense especially in barrier organs. Altered functionality of TH17 cells is associated with dysregulated tissue homeostasis resulting in an increased susceptibility for the development of autoimmune diseases. Thus, it is critical to identify mechanisms governing physiological as well as pathophysiological TH17 cell differentiation and identify strategies targeting TH17 cell differentiation in disease settings. Here, we identified the genome organizer Special AT-rich sequence-binding protein 1 (Satb1) as a pioneering factor for TH17 cell development. Satb1 is highly expressed in TH17 cells and loss of Satb1 prevents the differentiation of TH17 cells. As a consequence, expression of Satb1 in CD4+ T cells is required for the formation of TH17 cell-driven autoimmune diseases. Mechanistically, Satb1 mediates TH17 cell development through regulating accessibility of the Il2 gene locus and thereby preventing IL-2 signaling early during TH17 cell differentiation. Thus, Satb1 is critical by suppressing IL-2 expression during the formation of TH17 cells and may be a novel therapeutic target for the treatment of TH17 cell-driven autoimmune diseases

Regulation of pathogenic T helper 17 cell differentiation by steroid receptor coactivator-3

Project description:T helper 17 (Th17) cell development is programmed by the orphan nuclear receptor RORgt, but the underlying mechanism is not well understood. Nuclear receptor-mediated transcriptional activation depends on coactivators. Here we show that the steroid receptor coactivator-3 (SRC-3) critically regulates Th17 cell differentiation. Reduced incidence of experimental autoimmune encephalitis (EAE) associated with decreased Th17 cell generation in vivo was observed in mice with SRC-3 deletion specifically in T cells. In vitro, SRC-3 deficiency did not affect TGF-/IL-6-induced Th17 cell generation but severely impaired pathogenic Th17 differentiation induced by IL-1/IL-6/IL-23. Microarrays were used to showed that SRC-3 not only regulates IL-17A but also IL-1R1 expression. SRC-3 bound to Il17a and Il1r1 loci in a RORtdependent manner and was required for recruitment of the p300 acetyltransferase. Thus, SRC-3 is critical in RORt-dependent gene expression during Th17 cell-driven autoimmune diseases.

CIP2A negatively regulates Th17 differentiation

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.

Single-cell clonotype tracing identifies a stem-like intestinal Th17 population that gives rise to pathogenic effector T cells during autoimmunity

Project description:While intestinal Th17 cells are critical for maintaining tissue homeostasis, recent studies in both humans and mice have implicated their roles in the development of extra-intestinal autoimmune diseases such as multiple sclerosis. However, the mechanisms by which tissue Th17 cells mediate these dichotomous functions remain unknown. Here, we characterized the heterogeneity, plasticity, and migratory phenotypes of tissue Th17 cells in vivo by combining fate mapping with single-cell RNA sequencing to profile the transcriptomes and TCR clonotypes of over 84,000 Th17 cells at homeostasis and during CNS autoimmune inflammation. Inter- and intra-organ single-cell analyses revealed a homeostatic, stem-like TCF1+ IL-17+ SLAMF6+ population that traffics to the intestine where it is maintained by the microbiota, providing a ready-reservoir for the IL-23-driven generation of encephalitogenic GM-CSF+ IFNγ+ CXCR6+ T cells. Our study defines a direct relationship in vivo between IL-17+ non-pathogenic and GM-CSF+ and IFNγ+ pathogenic Th17 populations and provides, for the first time, a mechanism by which homeostatic intestinal Th17 cells direct extra-intestinal autoimmune disease.

Regulation of Th17 cell pathogenic function by miR-183/96/182

Project description:Th17 cells are key players in autoimmune diseases. However, the roles of non-coding RNAs in Th17 cells are largely unknown. Here, we show that deletion of the Dicer gene specifically in Th17 cells protects from experimental autoimmune encephalomyelitis (EAE). Th17 cells highly express the miR-183/96/182 cluster (miR-183C), in response to IL-6/STAT3 signaling. Moreover, miR-183C regulates pathogenic cytokine expression during Th17 development. Furthermore, transcription factor Foxo1 is one of functional targets of miR-183C in Th17 cells: Foxo1 negatively regulates the pathogenicity of Th17 cells and miR-183C represses Foxo1 expression. Collectively, our results demonstrate one of crucial roles for miR-183C cluster in regulation of Th17 cell function in autoimmune diseases.

RNA-seq of ATF7ip-deficient T cells

Project description:RNA-seq performed in ATF7ip-deficient T cells reveals a defect in Th17 gene induction secondary to increased IL-2 T helper 17 cells (Th17) are critical for fighting infections at mucosal surfaces, however, they have also been found to contribute to the pathogenesis of multiple autoimmune diseases and Th17 cells have been targeted therapeutically. Due to the role of Th17 cells in autoimmune pathogenesis, it is important to understand the factors that control Th17 development. Here we identify the activating transcription factor 7 interacting protein (ATF7ip) as a critical regulator of Th17 differentiation. Mice with T-cell-specific deletion of Atf7ip have impaired Th17 differentiation secondary to the aberrant overproduction of IL-2 with T-cell receptor (TCR) stimulation and are resistant to colitis in vivo. ChIP-seq studies identified ATF7ip as an inhibitor of Il2 gene expression through the deposition of the repressive histone mark H3K9me3 in the Il2-Il21 intergenic region. These results demonstrate a new epigenetic pathway by which IL-2 production is constrained and this may open up new avenues for modulating its production.

Induction of pathogenic Th17 cells by salt inducible kinase SGK-1 (NaCl)

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.
