Project description:Scleroderma is a lethal and currently irreversible autoimmune disease characterized by widespread tissue fibrosis and vasculopathy. Using cross-species comparative gene expression profiling we show that murine sclerodematous graft-versus-host disease (sclGVHD) approximates an “inflammatory” subset of human scleroderma and that both diseases demonstrate activation of the IL13 cytokine pathway. We report that both host myeloid cells expressing type I and II activated macrophage markers and graft T-cells produce IL13 and that host mice deficient in either IL13 or IL4Ra, an IL13 signal transducer, are protected from disease. This signaling pathway converges on a single gene, CCL2, which is coordinately upregulated in sclGVHD, in the human inflammatory scleroderma subset and in IL13 treated human dermal fibroblasts. Accordingly, treatment with antibodies to CCL2, and its murine homolog CCL12, prevent sclGVHD. Lastly, we provide evidence that IL13 pathway activation in early scleroderma patients correlates with modified Rodnan skin scores (mRSS). These data indicate that an inflammatory subset of scleroderma is driven by IL13 and may benefit from IL13 or CCL2 blockade. sample vs reference.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived IL4/IL13 treated BMDMs transcriptome profiling (RNA-seq) to quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods. Methods: BMDMs mRNA profiles of 8 weeks old wild-type (WT) mice were generated, stimulated with IL4/IL13, IL4/IL13+ TNF or TNF, deep sequenced, in triplicate, using Illumina NovaSeq 6000 platform. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm9). Conclusions: Our study represents the first detailed analysis of IL4/IL13 or IL4/IL13+TNF stimulated BMDMs, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.

Project description:The type 2 cytokines, interleukin (IL)-4, IL-5 and IL-13 reside within a multi-gene cluster in mammals. These cytokines represent the hallmark of type 2 immune responses controlling parasites and promoting tissue repair, as well as causing allergic diseases. Both innate and adaptive lymphocytes secrete type 2 cytokines with discordant production spectra. We took a holistic structural and functional view of the type 2 cytokine locus before and after activation, comparing innate (ILC2) and adaptive (Th2) lymphocytes to understand mechanisms underlying their distinctive programs. Rapid induction of IL-5 dominates in ILC2, whereas IL-4 does so in Th2 cells. Using high-resolution chromatin conformation capture we found that global cellular chromatin architecture remained constant, whereas the type 2 cytokine locus rapidly remodeled. In ILC2, Il13 and Il5 loci were aligned in proximity whereas Il4 locus was insulated. In Th2 cells, Il4 and Il13 positioned in proximity while the Il5 locus remained distal. Select REs were individually deleted in mice to confirm cell-type specific and activation-dependent roles in type 2 responses in vivo. Thus, contrary to the premise that chromatin architecture plays a minimal role in steady-state gene induction, signal-dependent remodeling of 3D configuration underlies the discordant cytokine outputs in ILC2s versus Th2 cells.
