Project description:High salt (NaCl) intake is a major risk factor for cardiovascular disease; high NaCl has also been shown to be a powerful modulator of pro-inflammatory immune cell polarization. To investigate the effect of high NaCl on the polarization of M(IL-4+IL-13) macrophages we performed gene expression analysis by microarray and genome wide histone modification (H3K4me3 and H4ac) analysis by ChIP-seq of murine bone marrow derived macrophages. Macrophages were polarized with recombinant IL-4 and IL-13 in vitro in the presence or absence of an additional 40mM of NaCl in the culture medium for 24h before analysis.

Project description:Macrophages, a key cellular component of inflammation, become functionally polarized in a signal- and context-specific manner. Th2 cytokines such as IL-4 polarize macrophages to a state of alternative activation that limits inflammation and promotes wound healing. Alternative activation is mediated by a transcriptional program that is influenced by epigenomic modifications including histone acetylation. To determine if Histone Deacetylase 3 (HDAC3) has a role in macrophage polarization including alternative activation, we have performed global gene expression analysis in macrophages with and without HDAC3 and with or without IL-4 exposure. From this data, we conclude that macrophages lacking histone deacetylase 3 (HDAC3) display a polarization phenotype similar to IL-4 induced alternative activation and furthermore are hyper-responsive to IL-4 stimulation. Mouse bone marrow derived macrophages were obtained from both control and HDAC3 KO animals and treated with vehicle control (BSA) or IL-4 for 24 hours. RNA was isolated and subjected to analysis using an Agilent Whole Genome Microarray Kit.

Project description:IL-6 induces IL4ralpha expression in macrophages. This mechanism is necessary to promote macrophage polarization towards an M2-phenotype and is crucial to limit the inflammatory response both upon obesity and LPS-endotoxemia. In this dataset, we include the expression data obtained from primary murine bone marrow-derived macrophages from control and IL6ralpha-deficient macrophages (n=4vs4) stimulated with interleukin-6 (IL-6) 8 samples were analyzed to compare control and IL6ralpha-deficient macrophages for their gene expression profiles upon stimulation with IL-6

Project description:STAT6 is a major transcription factor driving the polarization of Th2 cells in response to IL-4. STAT6 is phosphorylated by Jak1 and Jak3 kinases at the IL-4 receptor, after which phosphorylated STAT6 forms a homodimer and translocates into the nucleus. There STAT6 binds to specific DNA sequences, regulating the transcription of its target genes. Here we have analyzed on a genome wide level the STAT6 binding sites, after 1h and 4h of IL-4 induction, in naive human CD4+ T cells. Keywords: SRA Altogether 5 samples from 1 biological replicate were analyzed. Activated and IL-4 treated samples were compared to only activated or untreated samples to identify unique STAT6 binding sites after IL-4 induction.

Project description:The experiments were done using an Orbitrap Fusion or an Orbitrap Fusion Lumos mass spectrometer. Multiplexing was achieved using either TMT10 or TMT11 reagents and the SPS-MS3 method. Basic pH reversed-phase chromatography (bRPLC) was used for off-line pre-fractionation; 12 fractions were analyzed for proteome mappings (PMID: 26700037) and 24 fractions plus a phosphotyrosine-enriched sample for phosphoproteome mappings (PMID: 31606085). Phosphoproteome mappings were done using both HCD fragmentation with Orbitrap fragment ion detection and CID fragmentation with ion trap fragment ion detection (PMID: 29487189, PMID: 31606085). If multiple TMT sets were required to analyze all samples from an experiment two bridge channels pooled from all samples was used to connect the data from the individual TMT sets (PMID: 28892078).
Five proteomics experiments are described in the paper:

Project description:Macrophages polarize towards different subpopulations with distinct and partly antagonistic functions in various diseases. IFNγ/LPS-polarized M1-type macrophages can have antiangiogenic activity, whereas IL-4-induced M2-type macrophages can be proangiogenic and profibrotic. Therapeutic strategies to inhibit M2-type polarization while promoting M1-type polarization could serve to inhibit pathological angiogenesis and fibrosis. Here, by combining global quantitative time-course proteomics and phosphoproteomics with a small-molecule inhibitor screen we identify signaling events that promote specifically IL-4-induced and not IFNγ/LPS-induced macrophage polarization and found that the MEK inhibitor trametinib and the HDAC inhibitor panobinostat potently prevent M2-type macrophage polarization without inhibiting M1-type polarization. In contrast, selective B-Raf inhibition promotes M2-type polarization. Trametinib and panobinostat also blocked M2-type macrophage polarization and concomitantly angiogenesis and fibrosis in models of wound healing and neovascular age-related macular degeneration in vivo. Thus, these pharmacologic inhibitors could be utilized therapeutically to selectively block IL4-induced macrophage polarization and reduce pathologic angiogenesis and fibrosis.
