Project description:Macrophages were derived from the bone-marrow of 3 x fl/+ Dicer LysCre +/- (wild-type) and 3 x fl/fl Dicer LysCre +/- mice and stimulated with IL-4 (50ng/mL) for 72h. Total RNA was isolated and analyzed by gene array. In this experiment, we derived Dicer deficient bone-marrow macrophages using Dicer fl/+ LysM-Cre by Dicer fl/+ crossed mice to obtain Dicer fl/fl LysM-cre progeny (and Dicer deficient macrophages). Next, we studied the effects of IL-4 stimulation in macrophage with a deficiency in Dicer/microRNAs.
Project description:We report the genome-wide RNA sequencing analysis in Il10-/- bone marrow-derived macrophages (BMDMs) stimulated by lipopolysaccharide (LPS) where IL-10 effect in macrophage inflammatory response was examined in IL-10-deficient BMDMs upon LPS stimulation with addition of exogenous IL-10.
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:Macrophages were derived from the bone-marrow of 3 x fl/+ Dicer LysCre +/- (wild-type) and 3 x fl/fl Dicer LysCre +/- mice and stimulated with IL-4 (50ng/mL) for 72h. Total RNA was isolated and analyzed by gene array.
Project description:We report the genomic regions enriched in Histone Deacetylase 3 (HDAC3) in mouse bone marrow derived macrophages. Furthermore, we also report the genomic acetylation pattern on Histone 3, Lysine 9 (H3K9) in macrophages with and without HDAC3 and/or treated with Th2 cytokine IL-4. HDAC3 enriched genomic regions in mouse bone marrow dervied macrophages and H3K9Ac enriched genomic regions in wild-type macrophages and macrophages treated with IL-4 and/or deficient in HDAC3.
Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from bone marrow derived macrophages upon exposure to 20 ng/ml of IL-4 for 18 hours. Bone marrow derived macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.
Project description:To analyse the Irf4-dependent transcriptional changes of mouse bone marrow-derived macrophages (BMM) in response to IL-4, we have employed whole genome microarray expression profiling. For this purpose, bone marrow cells were isolated from 8 to 12 weeks old Irf4-deficient or heterozygous mice and cultured in the presence of the macrophage colony-stimulating factor (M-CSF) . After seven days of culture, IL-4 was added for 4 and 18 hours. Keywords: Mouse strain comparision; Gene expression profiling IL-4 induced gene expression was investigated in mouse bone marrow-derived macrophages (BMM) of Irf4-deficient or heterozygous mice. BMM were incubated with mouse recombinant IL-4 for 4 or 18 hours or without for 18 hours. Three independent experiments were performed at each time point (mock, 4 and 18 hours) using littermates for each experiment.
