Project description:Impairment of microglial clearance activity contributes to beta-amyloid (Aβ) pathology in Alzheimer disease (AD). While the transcriptome profile of microglia directs microglial functions, how the microglial transcriptome can be regulated to alleviate AD pathology is largely unknown. Here, we show that injection of interleukin (IL)-33 in an AD transgenic mouse model ameliorates Aβ pathology by reprogramming microglial epigenetic and transcriptomic profiles to induce a microglial subpopulation with enhanced phagocytic activity. These IL-33–responsive microglia (IL-33RM) express distinct transcriptome signature, highlighted by major histocompatibility complex class II genes, and restored homeostatic signature genes. IL-33–induced remodeling of chromatin accessibility and PU.1 transcription factor binding at the signature genes of IL-33RM control their transcriptome reprogramming. Specifically, disrupting PU.1–DNA interaction abolishes the microglial state transition and Aβ clearance induced by IL-33. Thus, we define a PU.1-dependent transcriptional pathway that drives the IL-33–induced functional state transition of microglia, resulting in enhanced Aβ clearance.

Project description:Connective tissue growthfactor (CTGF/CCN2) is a matricellular protein induced by transforming growth factor-beta (TGF-beta) and intimately involved with tissue repair and overexpressed in various fibrotic conditions. We have previously shown that keratinocytes in vitro downregulate TGF-beta induced expression of CTGF in fibroblasts by an interleukin-1 alfa (IL-1alfa) dependent mechanism. With this study we want to get a better overall perspective who fibroblasts respond on TGF-beta and in a TGF-Beta stinulated system, what effect addition of IL-1 alfa have. This to understand the expression of CTGF in human fibroblasts which in turn have implications for the pathogenesis of fibrotic conditions involving the skin. Microarray was performed on human skin fibroblast RNA from one patient, Fibroblasts were seeded in vitro as a control (Control, C), TGF-beta were added to fibroblasts and incubated for 16 h (addition of TGF-beta, T) and both IL-1alfa and TGF-beta were added to fibroblasts for 16 h (addition of IL-1alfa and TGF-beta, IT). Each condition (C,T and IT) were done in three replicates.

Project description:Dual-specificity phosphatase 8 is a MAPK phosphatase that dephosphorylates and inactivates the kinase JNK. DUSP8 is highly expressed in T cells; however, the in vivo role of DUSP8 in T cells remains unclear. Using T-cell-specific DUSP8 conditional knockout (T-DUSP8 cKO) mice, mass spectrometry analysis, chromatin-immunoprecipitation sequencing, and immune analysis, we found that DUSP8 interacted with Pur-α, stimulated interleukin-9 (IL-9) gene expression, and promoted Th9 differentiation. Mechanistically, DUSP8 dephosphorylated the transcriptional repressor Pur-α upon TGF-β signaling, leading to the nuclear export of Pur-α and subsequent IL-9 transcriptional activation. Furthermore, IL-9 mRNA levels were induced in Pur-α-deficient T cells. In addition, T-DUSP8 cKO mice displayed reduction of IL-9 and Th9-mediated immune responses in the allergic asthma model. Reduction of IL-9 mRNA levels in T cells and allergic responses of T-DUSP8 cKO mice was reversed by Pur-α knockout. Remarkably, DUSP8 protein levels and the DUSP8–Pur-α interaction were indeed increased in the cytoplasm of T cells from human asthma patients and atopic dermatitis patients. Collectively, DUSP8 induces TGF-β-stimulated IL-9 transcription and Th9-induced allergic responses by inhibiting the nuclear translocation of the transcriptional repressor Pur-α. DUSP8 may be a T-cell biomarker and therapeutic target for asthma and atopic dermatitis.

Project description:We report that Tripartite motif-containing 33 (Trim33), a protein that was previously associated with TGF-beta signaling, determines the pathogenic function of Th17 cells. Trim33 deficiency in T cells resulted in resistance to an autoimmune disease model. Lack of Trim33 did not impact TGF-beta signaling in mediating Foxp3 gene expression but greatly reduced TGF-beta induction of IL-17 production during Th17 cell differentiation. Importantly, we found TGF-beta not only increased IL-17 but also suppressed IL-10 expression; absence of Trim33 or Smad2 but not Smad4 in T cells enhanced IL-10 expression. In a Smad2-dependent manner, Trim33 was recruited to Il17 and Il10 gene loci and was crucial in appropriate histone modification accompanying Th17 differentiation. Our study thus demonstrates that Trim33, a non-canonical branch of TGF-beta signaling, programs the pro-inflammatory function of Th17 differentiation by promoting IL-17 and suppressing IL-10 expression. As a critical switch of pathogenic versus regulatory phenotype of T cells, Trim33 may be targeted in treating human autoimmune diseases.

Project description:Purpose: The molecular pathways underlying the development of innate lymphoid cells (ILCs) are mostly unknown. Results: TGF-β signaling programs the development of ILC2s from their progenitors. Specifically, the deficiency of TGF-β receptor II in bone marrow progenitors results in inefficient development of ILC2s, but not ILC1s or ILC3s. We found that hundreds of genes were changed in Tgfbr2-/- ILC2s compared to WT ILC2s (FDR < 0.1 and Fold-Change >1.5). Some ILC2-associated genes including Gata3, Il1rl1 (ST2), Il-5, Atxn1 (Sca1), and Ccr4 were decreased in Tgfbr2-/- ILC2s, according to RNA-seq analysis Conclusions: TGF-β upregulates the expression of the IL-33 receptor gene Il1rl1 (encoding IL-1 receptor-like 1, also known as ST2) in ILC2p and common helper-like innate lymphoid progenitors (CHILP), at least partially through the MEK-dependent pathway. These findings identify a function of TGF-β in the development of ILC2s from their progenitors.

Project description:CD4+ T cells that selectively produce interleukin (IL)-17, are critical for host defense and autoimmunity. Crucial for T helper17 (Th17) cells in vivo, IL-23 has been thought to be incapable of driving initial differentiation. Rather, IL-6 and transforming growth factor (TGF)-β1 have been argued to be the factors responsible for initiating specification. Herein, we show that Th17 differentiation occurs in the absence of TGF-β signaling. Neither IL-6 nor IL-23 alone efficiently generated Th17 cells; however, these cytokines in combination with IL-1β effectively induced IL-17 production in naïve precursors, independently of TGF-β. Epigenetic modification of the Il17a/Il17f and Rorc promoters proceeded without TGF-β1, allowing the generation of cells that co-expressed Rorγt and T-bet. T-bet+Rorγt+ Th17 cells are generated in vivo during experimental allergic encephalomyelitis (EAE), and adoptively transferred Th17 cells generated with IL-23 in the absence of TGF-β1 were more pathogenic in this experimental disease. These data suggest a new model for Th17 differentiation. Consistent with genetic data linking the IL23R with autoimmunity, our findings re-emphasize the role of IL-23 and therefore have important implications for the development of new therapies.
