Genome-wide analysis of mouse macrophages stimulated with IL-4 (Biogel and thioglycollate macrophages) (Affymetrix)

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 Thioglycollate and Biogel elicited peritoneal macrophages exposed to 20 ng/ml of IL-4 for 18 hours. Biogel and thioglycollate elicited macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.

The Paradigm of Macrophage Polarization is not Applicable per seto Human Circulating Monocytes

Project description:Macrophage activation is required for the control of innate and adaptive immune responses. The classification in M1 and M2 macrophages based on a combination of small numbers of membrane and soluble markers is operational in murine and human macrophages. If this classification may be extended to circulating monocytes is not elucidated. To answer such question, human monocytes were stimulated for 6 and 18 hours with IFN-gamma and IL-4, two canonical agonists of M1/M2 polarization in macrophages, and gene expression programs were investigated with whole genome microarrays. The temporal analysis of these programs showed marked differences to both IFN-gamma and IL-4. In 6-h stimulated monocytes, gene categories related to inflammatory and immune responses were enriched, and these monocytes exhibited a M1 and M2 polarization in response to IFN-gamma and IL-4, respectively, as found in macrophages. In 18-h stimulated monocytes, the categories related to innate immunity and metabolic pathways were enriched in response to IFN-gamma and IL-4, whereas PPAR signaling pathway was specifically enriched in response to IL-4. In addition, the M1 and M2 polarization induced by IFN-gamma and IL-4, respectively, was replaced by an original transcriptional program that did not depend on IFN-gamma and IL-4. This program appeared as networks around chemokines, NF-kappaB/MAP kinase pathways and MHC class II molecules. These results clearly demonstrated that monocyte activation consisted of an early polarized stage likely involved in effector responses and a delayed stage that may regulate host responses. The establishment of databases on human circulating monocytes using high throughput methods may be critical for pathophysiological and clinical non-invasive studies. Peripheral blood mononuclear cells (PBMCs) were isolated from leukopacks from normal blood donor buffy coats (Etablissement FranÃ§ais du Sang, Marseille, France) by Ficoll density gradient

The multifaceted responses of human monocytes to IFN-gamma and IL-4 are not reducible to M1/M2 polarization of Macrophages

Project description:Macrophages are known to be polarized into inflammatory (M1) and immunoregulatory (M2) cells when they are stimulated by agonists such as IFN-gamma and IL-4, respectively. If circulating monocytes may be polarized in response to T cell signals is often misguidedly deduced from macrophage results. Here the transcriptional responses of human CD14+ monocytes to IFN-gamma and IL-4 were analyzed using whole genome microarrays. A principal component analysis and hierarchical clustering showed that monocyte and macrophage responses were distinct. Monocytes stimulated with IFN-gamma and IL-4 for 6 hours exhibited some features of macrophage polarization. Indeed, when 80 genes considered as M1 and M2 genes were analyzed, we found that M1 genes were modulated in response to IFN-gamma and that M2 genes were modulated in response to IL-4. The M1 polarization of monocytes was transient because only M2 genes were modulated when monocytes were stimulated with IFN-gamma and IL-4 for 18 hours. However, the activation of monocytes by IFN-gamma and IL-4 could not be reduced to M1/M2 polarization status. Indeed, monocytes exhibited early specific signatures composed of 46 and 39 up-regulated genes in response to IFN-gamma and IL-4, respectively, and a late signature common to both molecules that consisted of 57 up-regulated genes. Taken together, these results demonstrated the extreme plasticity of human monocytes and suggested the existence of a core transcriptional termination program. Using early and late signatures might be pertinent to investigate monocyte activation in inflammatory or infectious diseases. Monocytes were stimulated with IFN-gamma (20ng/mL) or IL-4 (20ng/mL) for 6 and 18 hours or culture for 6 and 18 hours without agonist (Unstimulated samples). Monocytes-derived-macrophages (MDM) stimulated with IFN-gamma and IL-4 for 18 hours were used as controls. Each microarray is derived from a single biological sample.

microRNA expression profiling of polarized macrophages

Project description:microRNAs are small non-coding RNAs that regulate gene expression at a post-translational level, and play a crucial role in the development of cells of the immune system. Macrophages are essential for generating inflammatory reactions upon tissue damage and encountering of invading pathogens, yet modulation of their immune responses is critical for maintaining tissue homeostasis. Macrophages can present different phenotypes, depending on the cytokine environment they encounter in the affected tissues. In this study, we have identified expression signatures of miRNAs that are differentially regulated during maturation of monocytes and polarization of macrophages by cytokines. We present a comprehensive characterization of miRNA expression in human monocytes and M1, M2a and M2c polarized macrophages, using next-generation Sequencing by Oligonucleotide Ligation and Detection (SOLiD). We have analyzed freshly isolated human monocytes and 5 day monocyte-derived macrophages unstimulated, or stimulated with IFNgamma+TNFalpha (M1), IL-4 (M2a) or IL-10 (M2c).

The immunomodulatory effects of IL-4 on monocyte-derived macrophages

Project description:To explore the effects of IL-4 on tumor-associated macrophagess, we first sorted CD14+ monocytes from peripheral blood mononuclear cells of healthy donors using magnetic-activated cell sorting and then induced their differentiation into macrophages by culture with M-CSF for 5 days. We then stimulated these macrophages with or without IL-4 (20 ng/ml) for 6 hours and examined gene expression using a cDNA microarray. IL-4 stimulated gene expression on monocyte-derived macrophages was measured at 6 hours after exposure to doses of 20 ng/ml IL-4.

Transcription profiling of human monocytes cultured in the presence of M-CSF for 7 days and polarized to M1 or M2 cells to characterize human monocyte-to-macrophage differentiation and polarization

Project description:Monocytes mature to macrophages in the presence of the lineage determining cytokine M-CSF. They can be further polarized into M1 or M2 macrophages with distinct functional properties. We used microarrays to detail the global programme of gene expression underlying macrophage maturation and polarization and identified distinct classes of up-regulated genes during this process. Experiment Overall Design: Freshly isolated monocytes were cultured in the presence of M-CSF for 7 days, and then polarized to M1 or M2 cells. The study includes Monocytes at day 0, macrophages at day 3 and 7, M1 and m2 polarized macrophages.
