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.

Roles of STAT3 and STAT5 in regulation of gene expression under Th17 differentiation

Project description:Interleukin 2 (IL-2), a cytokine linked to human autoimmune diseases, limits IL-17 production. We show that deletion of Stat3 in T cells abrogates IL-17 production and attenuates autoimmunity associated with IL-2 deficiency. While STAT3 induces IL-17 and ROR?t and inhibits Foxp3, IL-2 inhibited IL-17 independently of Foxp3 and ROR?t. We found that STAT3 and STAT5 bound to multiple common sites across the Il17 genetic locus. The induction of STAT5 binding by IL-2 was associated with a reduction in STAT3 binding at these sites and the inhibition of associated active epigenetic marks. Titrating the relative activation of STAT3 and STAT5 modulated TH17 cell specification. Thus, the balance rather than the absolute magnitude of these signals determines the propensity of cells to make a key inflammatory cytokine. The roles of STAT3 and STAT5 in regulation of gene expression under Th17 differentiation was investigated. Affymetrix Mouse Genome 430 2.0 Arrays were used to evaluate global gene expression.

Genome wide STAT3 RNAi expression profiling data from Thp,Th0 and Th17 cells

Project description:STAT3 is an immidiate regulator of Th17 differentiation. STAT3 difieciency downmodulate Th17 specific genes and Th17 responses. Therefore, we intend to identify genome wide targets of STAT3. We used microarrays to profile gene expression of STAT3 regulated genes during Th17 polarization. Total RNA was extracted from non-targeting and STAT3 siRNA treated Thp, Th0 and Th17 cell samples from different time points. Total RNA subjected to poly-A selection and hybridization on Affymetrix microarrays.

Genome-wide binding of STAT3 and STAT5 under Th17 conditions (ChIP-Seq)

Project description:Interleukin 2 (IL-2), a cytokine linked to human autoimmune diseases, limits IL-17 production. We show that deletion of Stat3 in T cells abrogates IL-17 production and attenuates autoimmunity associated with IL-2 deficiency. While STAT3 induces IL-17 and RORγt and inhibits Foxp3, IL-2 inhibited IL-17 independently of Foxp3 and RORγt. We found that STAT3 and STAT5 bound to multiple common sites across the Il17 genetic locus. The induction of STAT5 binding by IL-2 was associated with a reduction in STAT3 binding at these sites and the inhibition of associated active epigenetic marks. Titrating the relative activation of STAT3 and STAT5 modulated TH17 cell specification. Thus, the balance rather than the absolute magnitude of these signals determines the propensity of cells to make a key inflammatory cytokine. The genome-wide binding of STAT3 and STAT5 under Th17 conditions was investigated by CHIP-seq.

Genome-wide detection of STAT3 binding sites in human Th17 cells

Project description:STAT3 is a major transcription factor driving the polarization of Th17 cells in response to IL-6, TGF-Î² and IL1-Î². STAT3 is phosphorylated and forms a homodimer and translocates into the nucleus. There STAT3 binds to specific DNA sequences, regulating the transcription of its target genes. Here we have analyzed on a genome wide level the STAT3 binding sites, after 0.5h and 4h of IL-6, TGF-Î² and IL1-Î² induction, in naive human CD4+ T cells. Altogether 2 samples from 1 biological replicate were analyzed.
