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:Immunity to fungal infections is mediated by cells of the innate and adaptive immune system. Activation of immune cells requires Ca2+ influx through the Ca2+ channel ORAI1, which is activated by stromal interaction molecule 1 (STIM1). Th17 cells are essential for immunity to C. albicans infection and require Ca2+ influx for expression of IL-17A and other Th17 cytokines. In mice, deletion of STIM1 and thus Ca2+ influx in all immune cells enhanced susceptibility to mucosal C. albicans infection, whereas T cell-specific deletion of STIM1 impaired immunity to systemic C. albicans infection. STIM1 deletion in CD4 T cells had different effects on gene expression programs in pathogenic (proinflammatory) and non-pathogenic Th17 cells. STIM1 deletion in non-pathogenic Th17 cells, which are required for antifungal immunity, compromised the expression of genes in several metabolic pathways including Foxo and HIF-1a signaling as well as the TCA cycle and oxidative phosphorylation (OXPHOS). Consequently, STIM1 deficient non-pathogenic Th17 cells had impaired glycolysis and mitochondrial respiration. By contrast, STIM1 deletion in pathogenic Th17 cells showed only attenuated mitochondrial function but normal glycolysis.

Project description:Pathogenic Th17 cells play an important role in many autoimmune and inflammatory diseases. Their function is dependent on signaling through the T cell receptor (TCR) and cytokines that activate the transcription factor signal transducer and activator of transcription 3 (STAT3). TCR engagement activates stromal interaction molecule 1 (STIM1) and calcium (Ca2+) influx through the Ca2+ release-activated Ca2+ (CRAC) channel. We here show that deletion of STIM1 and Ca2+ influx in T cells expressing a hyperactive form of STAT3 (STAT3C) attenuates pathogenic Th17 cell function and multiorgan inflammation associated with STAT3C expression. Deletion of STIM1 in pathogenic Th17 cells impairs the expression of nuclear encoded mitochondrial electron transport chain genes and oxidative phosphorylation (OXPHOS) but enhances reactive oxygen species (ROS) production. Deletion of STIM1 or inhibition of OXPHOS is associated with impaired Th17 cell function and a non-pathogenic Th17 gene expression signature. Our findings establish STIM1 and Ca2+ signals as a critical regulator of OXPHOS and oxidative stress in pathogenic Th17 cells and multiorgan inflammation.

Project description:Identifying factors controlling pathogenic-Th17 cells is of importance, for their vital role in inflammation and immune-pathology. While intricate ER stress signals have been implicated in T cell biology, its role in Th17 cells remain poorly understood. Here, we demonstrated that HMGCS1, a cholesterol biosynthesis precursor enzyme, was highly induced by inflammatory cytokines and preferentially expressed by pathogenic-Th17 cells in vitro and in vivo. HMGCS1 specifically dictated pathogenic-Th17 cell differentiation and augmented autoimmune diseases. Nonetheless, HMGCS1 role in pathogenic-Th17 cells was independently of cholesterol metabolism but necessitated its catalytic Cys129 residue. Notably, HMGCS1 leveraged IRE1a-XBP1s-dependent ER stress response which was essential for pTh17 cell generation and pathogenicity by transcriptionally activating Rorc loci. Mechanistically, HMGCS1 located to the ER membrane, where it bound and stabilized IRE1a protein via restraining IRE1a interaction with K48-linked ubiquitination-dependent E3 ligase MARCH5. Of note, interfering HMGCS1 and ER stress impeded pathogenic-Th17 immunity and mitigated autoimmune diseases. Therefore, our work reveals a non-canonical axis wherein HMGCS1 sustains ER stress to license pTh17 cell differentiation during autoimmune responses.
