Project description:Interleukin (IL)-37 suppresses systemic and local inflammation. It is expressed in the epidermis, the external layer of the skin, and is decreased in inflammatory skin diseases including atopic dermatitis (AD) and psoriasis. Therefore, an agent applied topically on the skin that can increase IL-37 could be promising for treating AD and psoriasis; however, the mechanism regulating IL-37 remains largely unknown. Given that IL-37 expression is induced in differentiated keratinocytes, a major component of the epidermis, and that activation of aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor, promotes keratinocyte differentiation, we hypothesized that AHR might be involved in the IL-37 expression in human keratinocytes. We analyzed normal epidermal human keratinocytes (NHEKs) treated with tapinarof and Galactomyces fermentation filtrate (GFF), which are potent AHR modulators. We found that tapinarof and GFF upregulated IL-37 in NHEKs, which was canceled by the knockdown of AHR using siRNA transfection, indicating that AHR mediates IL-37 expression in NHEKs. Furthermore, we found that the knockdown of IL-37 resulted in the upregulation of IL-33, an alarmin cytokine with crucial roles in the pathogenesis of AD and psoriasis. These findings suggest that IL-37 negatively regulates IL-33 expression in NHEKs. Finally, we examined whether tapinarof and GFF treatment modulates IL-33 expression in NHEKs. Such treatment inhibited IL-33 expression, which was partially reversed by the knockdown of either AHR or IL-37. Taken together, our findings provide the first evidence that tapinarof and GFF could have potential to prevent IL-33-overexpressing disorders such as AD and psoriasis via the AHR/IL-37 axis.

Project description:IL-33 is a nuclear cytokine from the IL-1 family that plays important roles in health and disease. Under healthy conditions, IL-33 is constitutively expressed to high levels in the nucleus of producing cells in various human and mouse tissues. The extracellular function of IL-33 cytokine has been well documented, but it remains unclear whether intracellular nuclear IL-33 has additional functions in the nucleus. Here, we used a global proteomic approach based on quantification of 5000 individual proteins by high-resolution mass spectrometry to compare the extracellular and intracellular roles of IL-33 in primary human endothelial cells, a major source of IL-33 protein in human tissues. Large-scale analysis of protein expression was performed either after stimulation of the cells with the IL-33 mature form IL-3395-270 (during 6h or 24h) or after siRNA knockdown of intracellular IL-33 (two experiments, each with a different pool of distinct siRNAs, noted siRNA1 and siRNA2). In each case, proteins were fractionated by 1D SDS-PAGE in 12 gel bands, and label-free quantitative analysis was performed. The present dataset contains the files for the two experiments of knockdown of endogenous nuclear IL-33 expression: - RNA silencing strategy 1. Knockdown of endogenous nuclear IL-33 expression was performed with a pool of four distinct siRNAs (Dharmacon ON-TARGETplus SMARTpool IL-33 siRNAs) that have been specifically modified for efficient silencing of the target gene with reduced off-target effects. Cells transfected with these siRNA duplexes (si1) were compared with those transfected with the provided controls (CTsi1). Three independent biological replicates (noted _A, _B, _C) were prepared and analyzed for each condition, leading to 6 different samples. Each of them was fractionated into 12 gel bands analyzed by nanoLC-MS/MS, leading to 72 raw files. - RNA silencing strategy 2. The second knockdown strategy was based on the use of an independent pool of three siRNAs targeting IL-33, predesigned by another provider using new and critical siRNA design rules (Sigma MISSION Predesigned Il-33 siRNAs based on Rosetta siRNA design algorithm). Cells transfected with these siRNA duplexes (si2) were compared with those transfected with the provided controls (CTsi2). Three independent biological replicates (noted _A, _B, _C) were prepared and analyzed for each condition, leading to 6 different samples. Each of them was fractionated into 12 gel bands analyzed by nanoLC-MS/MS, leading to 72 raw files.

Project description:In this study we aim to determine the role of IL-4/STAT6 in gene expression in human keratinocytes using RNA-sequencing approach. Human keratinocytes were cultured for 2 or 5 days with calcium chloride to induce terminal differentiation as determined by the expression of epidermal differentiation complex genes. The cells were then stimulated with IL-4 for 3 and 24 hours, or along the 5 days culture period. We observed that IL-4 inhibits fully differentiation of keratinocytes, induces genes involved with production of inflammatory mediators, and reduces the healing capacity of human keratinocytes. Moreover, STAT6 controlled important genes involved with calcium binding, inflammation and epidermis development. Human keratinocytes were differentiated with calcium chloride for 2 days and incubated with media alone or 20ng/ml of recombinant human IL-4 for 3 and 24 hours. Human keratinocytes were differentiated with calcium chloride for 5 days with or wihout recombinant human IL-4 (20ng/ml). Keratinocytes transfected with control or STAT6 siRNA were differentiated with calcium chloride for 2 days and then stimulated with recombinant huma IL-4 for 24 hours.

Project description:IL-17C is important for the pathogenesis of inflammatory diseases such as IBD and psoriasis. We found that IL-17C is highly induced in a murine model of psoriasis. Recent results suggest that IL-17C can target epithelial cells that express both IL-17RA and IL-17RE receptor chains. Here we identify genes induced in response to IL-17C treatment of human keratinocytes to provide the tools for dissection of the IL-17C signaling pathway. Human keratinocytes, HEKn, were incubated in the absence (n = 3) and presence (n = 5) of 500 ng/ml recombinant human IL-17C for 3 and 24 hours. Whole RNA was isolated via RNeasy kit (Qiagen).

Project description:Interleukin-33 (IL-33) is a novel member of the IL-1 family of cytokines that plays diverse roles in the regulation of immune responses. IL-33 exerts its effects by binding to a heterodimeric receptor complex consisting of interleukin-1 receptor like 1 (IL1RL1) and an accessory receptor protein IL-1RAcP resulting in the production and release of proinflammatory cytokines. A detailed understanding of the signaling pathways activated by IL-33 remains elusive. To elucidate IL-33 mediated signaling, we performed a global quantitative phosphoproteomic analysis using stable isotope labeling by amino acids in cell culture. Employing anti-phosphotyrosine antibodies and titanium dioxide-based enrichment strategies, we identified 6,207 phosphorylation sites mapping to 2,013 phosphoproteins of which more than 185 phosphosites are regulated by IL-33 stimulation. Our findings will greatly expand the understanding of IL-33 signaling and provide novel therapeutic targets for IL-33/IL-33R-associated diseases in humans.

Cells cultured in the absence of IL-33 were used as control (CTil33). Three independent biological replicates (noted _A, _B, _C) were prepared and analyzed for each condition, leading to 9 different samples. Each of them was fractionated into 12 gel bands analyzed by nanoLC-MS/MS, leading to 108 raw files.

Project description:The effects of IL-33 on ST2+ Treg cells were not studied thouroughly. We FACS-sorted in vitro expanded ST2+ Treg cells from C57BL/6 Foxp3-IRES-mRFP (B6 FIR) mice. We next used RNA-seq techonology to define how recombinant IL-33 (rIL-33) may impact mouse Treg by to assessing the transcriptome of IL-33-stimulated ST2+ Treg cells compared to that of untreated ST2+ Treg cells. Our data revealed that ST2+ Treg stimulated with rIL-33 for 6 hours exhibited increased expression of Il10 and Il13 compared to unstimulated ST2+ Treg cells.

Project description:Determination of the molecular mechanism of IL33 on glioma cells Since IL-33 is known to associate with chromatin and regulate transcriptional activity and that nuclear expression of IL-33 increases glioma progression, we determined Nuclear IL-33 regulates the expression and secretion of inflammatory cytokines in glioma cells. Using these parameters 340 genes were induced by the ectopic expression of IL-33 and an additional 377 genes were downregulated. Gene ontology terms over-represented in the genes induced by IL-33 include three major clusters that associate with cytokine activity and inflammation
