Project description:Analyses of IL-1b-induced transcriptome in various skin-relevant cell types (keratinocytes, dermal fibroblasts, dermal microvascular endothelial cells, mononuclear immune cells) by RNASeq method disclosed an overlap of upregulated molecules among the different cell types. Matching cellular IL-1 receptor levels, dermal fibroblasts showed both the strongest and broadest IL-1b response.

Project description:IL-1B is an important cytokine that is often found to be up-regulated during osteoarthritic and rheumatoid joint diseases. It is viewed as a catabolic factor, inducing enzymes that allow for the degradation of the cartilage extracellular matrix and also has essential roles as an autocrine and paracrine factor in fibronectin fragment-mediated degradation. It can also reduce the synthesis of the major cartilage components, type II collagen and aggrecan. On the other hand, IL-1B also has the ability to induce the growth and morphogenic factor BMP-2. During joint diseases, IL-1B is synthesized by both synovial cells and chondrocytes. Addition of IL-1 biological antagonists such as IL-1 receptor antagonists can suppress cartilage degradation in vitro. Thus, the production of IL-1B could act as the first step in mediating a cascade of other mediators in cartilage which could be relevant to the fate of the cartilage. In order to obtain a global picture of the effect of IL-1B production on human adult articular chondrocytes, we analyzed changes in gene expression induced by IL-1B by microarray analysis. We found that IL-1B has a diverse effect on gene expression profile in chondrocytes. One of the predominant responses that we observed in adult human articular chondrocytes on exposure to IL-1B is a dramatic increase in a large set of chemokines and other genes related to the inflammatory cascade. Keywords: Gene response to IL-1B (10 ng/ml) Cartilage was obtained from adult human tissue donors with above the knee amputations due to chondrosarcoma or traumatic injury or from autopsy. Chondrocytes were isolated following established protocols, maintained in high density, and treated with IL-1B (10 ng/ml). Chondrocytes treated with buffer only served as the untreated control. The experiment was carried out in duplicate. Total RNA was extracted from these chondrocytes, labeled with fluorophores (Cy3 or Cy5) and analyzed for expression changes using the Human Operon/Qiagen v3.0 oligonucleotide array. The analysis was repeated with the fluorophore dyes exchanged between the untreated and experimental RNAs.

Project description:IL-1 plays an important role in atherosclerosis, and alters expression of a number of genes involved in atherosclerotic plaque development and progression. Smooth muscle cells play important roles in atherosclerotic plaque formation and stability, so this study was undertaken to determine the global effects of IL-1b on gene expression in smooth muscle cells in vitro. Cultured rat aortic smooth muscle cells were treated with IL-1b (2.5 ng/mL) or vehicle (0.1% BSA) for 24 hours prior to harvest.

Project description:Cytokines have been shown to play a key role in the destruction of beta cells. In the rat insulinoma cell line (INS-1ab) overexpressing pancreatic duodenum homeobox 1 (Pdx1) increases sensitivity to Interleukin 1b (IL-1b). To elucidate mechanisms of action underlying Pdx1 driven potentiation of beta-cell sensitivity to IL-1β, we performed a microarray analysis of INS-1ab cells with and without Pdx1 overexpression exposed to IL-1β between 2h and 24h. INS-1ab cells were cultured with or without 500 ng/ml doxycycline (+/- DOX). After 24 h, 40 ng/ml IL-1b was either added or not (+/- IL-1b). Cells were harvested either 2h, 4h, 6h, 12h or 24h after addition of IL-1b. Four biological replicates for each of the eight groups.

Project description:ILC2s regulate type2 immune responses and protect against helminth infection. We found that ILC2s can be expanded in the presence of a combination of cytokines IL-2 and IL-1b. To better understand the functional and phenotypic consequence of IL-1β activation of ILC2s, we utilized whole transcriptome sequencing (RNA-seq) of freshly isolated ILC2s and IL-1β-primed ILC2s. Differential expression analysis revealed a substantial number of genes underwent significant change between the two conditions (total 4,744 gene, FDR<0.01, Fold change >2), among which 3,871 genes were upregulated in IL-1β –primed ILC2s.

Project description:IL-36 cytokines have recently emerged as mediators of inflammation in autoimmune conditions including psoriasis vulgaris (PsV) and generalized pustular psoriasis (GPP). This study used RNA-seq to profile the transcriptome of primary epidermal keratinocytes (KCs) treated with IL-1B, IL-36A, IL-36B or IL-36G. We identified some early IL-1B-specific responses (8 hours post-treatment), but nearly all late IL-1B responses were replicated by IL-36 cytokines (24 hours post-treatment). Type I and II interferon genes exhibited time-dependent response patterns, with early induction (8 hours) followed by no response or repression (24 hours). Altogether, we identified 225 differentially expressed genes (DEGs) with shared responses to all 4 cytokines at both time points (8 + 24 hours). These involved up-regulation of ligands (IL1A, IL1B, IL36G) and activating proteases (CTSS), but also up-regulation of inhibitors such as IL1RN and IL36RN. Shared IL-1B/IL-36 DEGs overlapped significantly with genes altered in PsV and GPP skin lesions, as well as genes near GWAS loci linked to autoimmune and autoinflammatory diseases (e.g., PsV, psoriatic arthritis, IBD, primary biliary cholangitis). Inactivation of MyD88 adapter protein using CRISPR/Cas9 completely abolished expression responses of such DEGs to IL-1B and IL-36G stimulation. These results provide a global view of IL-1B and IL-36 expression responses in epidermal KCs with fine-scale characterization of time-dependent and cytokine-specific response patterns. Our findings support an important role for IL-1B and IL-36 in autoimmune or autoinflammatory conditions and show that MyD88 adaptor protein mediates shared IL-1B/IL-36 responses.

Project description:We replicated the intricate conditions of the venous valve pocket using a state-of-the-art hypoxia chamber with software-controlled oxygen cycling. We comprehensively studied the effects of sustained and intermitted hypoxia alone or in combination with IL-1b to mimic VTE-associated inflammatory stimuli on primary monocytes. Our transcriptome analysis revealed that sustained hypoxia limited the pro-inflammatory response induced by IL-1b, and triggered a metabolic shift in the monocyte transcriptome. On the other hand, intermittent hypoxia alone had a modest effect, but in combination with IL-1b it significant altered the expression of 2207 genes. Notably, intermittent hypoxia enhanced the IL-1b -stimulatory effects on several chemokine and interleukin genes (e.g., IL-19, IL-24, IL-32, MIF), as well as genes involved in coagulation (thrombomodulin) and fibrinolysis (VEGFA, MMP9, MMP14 and PAI-1. The RNA seq data are paired with validations on protein level in the published paper. Our findings provide valuable insights into how the different hypoxic profiles shape the immunothrombotic response of monocytes and shed new light on the early events in the pathogenesis of venous thrombosis.
