Interleukin-27 treated human macrophages induce the expression of novel miRNAs which may mediate anti-viral properties (affy)

ABSTRACT: In this study, we hypothesized that IL-27 could induce the expression of novel miRNAs in macrophages which may have functional relevance in terms of anti-viral activity. In this study, primary monocytes were differentiated into macrophages using M-CSF (M-Mac) or with a combination of M-CSF and IL-27 (I-Mac) for seven days. Following this, total RNA was extracted from these cells and deep sequencing was performed, in parallel with gene expression microarrays. Using the novel miRNA discovery software, miRDeep, seven novel miRNAs were discovered in the macrophages, four of which were expressed higher in I-Mac (miRNAs 2.1, 8.1, 9.1 and 14.2) whilst three were detected in both M-Mac and I-Mac (miRNAs 9.3, 13.6 and 15.8). The expression of six of the seven novel miRNAs was highly correlated with qRT-PCR using specific primer/probes designed for the novel miRNAs. Gene expression microarray further demonstrated that a number of genes were potentially targeted by these differentially expressed novel miRNAs. Gene expression microarrays from 3 samples of microphage treated with M-CSF (M-MAC) were compared with 3 samples of micropahge treated with M-CSF + IL-27 (I-MAC)

Expression analysis of dendritic cells, macrophages and monocytes

Project description:Expression profiles at different time points during dendritic cell differentiation (induced by specific culture conditions) including monocytes as well as expression profiles between monocytes and completely differentiated cells (macrophages at day7 and dendritic cells at day7, respectively) were compared. Monocyte-derived dendritic cells (DC) were obtained by culturing elutriated monocytes with 20U/ml IL-4, 280U/ml GM-CSF and 10% FCS; monocyte-derived macrophages (MAC) were obtained by culturing elutriated monocytes with 2% AB serum. Three to seven biological replicates that are derived from independent healthy donors were included. One-color based gene expression. 2 datasets: dendritic cell kinetic study and comparison of monocyte, macrophage, and dendritic cells

Sublytic membrane attack complex drives glycolysis and mitochondrial dysfunction with inflammatory consequences in human monocyte-derived macrophages

Project description:The terminal stage of the complement activation pathways, the membrane attack complex (MAC), is upregulated in diabetic and rheumatoid arthritis patients, contributing pathologically by increasing inflammation. Previous research has highlighted that a sublytic dose of MAC can initiate NLRP3 inflammasome activation via calcium influx and loss of mitochondrial membrane potential. Here, we show that sublytic concentrations of MAC mediate a previously undescribed perturbation in cellular energy metabolism in human monocyte-derived macrophages, by phenotypic skewing towards glycolysis and upregulation of glycolysis-promoting genes. Sublytic MAC concentrations drive mitochondrial dysfunction, characterised by a fragmented mitochondrial morphology, loss of maximal respiratory response, depleted mitochondrial membrane potential as well as increased mitochondrial reactive oxygen species production. The consequences of these alterations in glycolytic metabolism and mitochondrial dysfunction lead to NLRP3 inflammasome activation, driving gasdermin D formation and IL-18 release. This novel link between sublytic MAC and immunometabolism, with direct consequences for downstream inflammatory processes, is important for development of novel therapeutics for areas where MAC may mediate disease.

Characterization of miRNA expression profile during human monocytes differentiation in macrophages

Project description:Colony-stimulating factor-1 (CSF-1) triggers the differentiation of human peripheral blood monocytes into macrophages through an integrated cytokine/transcription factors circuitry. However, the role of miRNAs in the development of macrophages is just beginning to be explored. Here, we used microarray profiling to identify miRNAs involved in this molecular circuitry. In this study, a sample of RNA extracted from human monocytes were compared with a sample of RNA extracted from the same monocytes after 6 days of CSF-1 treatment.

Methylation data and effect of JAK3 inhibition on human MO-to-DC and MO-to-MAC differentiation

Project description:Comparison of the DNA methylation profiles of CD14+ monocytes from human peripheral blood with derived dendritic cells (DCs) and macrophages (MACs) obtained by exposure with GM-CSF/IL-4 and GM-CSF, respectively. Effects on the methylation profiles of DCs and MACs of JAK3 inhibitor PF-956980 The methylation profiles of bisulfite-modified DNA of human CD14+ monocytes were compared with derived dendritic cells (DCs), macrophages (MACs) following GM-CSF/IL-4 and GM-CSF incubation, and DC and MAC samples incubated with JAK3 inhibitor PF-956980 using the Infinium HumanMethylation450 BeadChips (Illumina, Inc., San Diego, CA,). This platform allows the interrogation of >485,000 methylation sites per sample at single-nucleotide resolution, and comprises an average of 17 CpG sites per gene in the 99% of RefSeq genes. 96% of CpG islands are covered, with additional coverage in CpG island shores and the regions flanking them. The samples were hybridized in the array following the manufacturerÃ¢ÂÂs instructions. Total DNA isolated by standard procedures from CD14+ cells (total monocytes, MOs) corresponding to three sets of samples of monocytes (MOs), derived DCs and MACs (DCs and iMACs; DMSO as these samples were differentiated in the absence of JAK3 inhibitors) and DCs and MACs differentiated in the presence of JAK3 inhibitor PF-956980.

Transcriptomics comparisons of Mac-T cells versus mammary tissue during late pregnancy and peak lactation

Project description:The bovine mammary epithelial cell line Mac-T has been used to study mammary gland in vitro. The reliability of this system to study mammary gland has not been tested using genomics approaches. In the present experimetn a direct transcriptomics comparison between Mac-T cells and mammary tissue at -30 and at 60 day in milk (DIM) is performed. Data indicated that Mac-T cells and mammary tissue had a substantially different transcriptome with a larger difference between Mac-T cells and lactating mammary tissue (i.e., 60 DIM) compared to non-lactating mammary tissue (i.e., -30 DIM). In addition, data indicated that the Mac-T cells substantially differ with mammary tissue in lactation-specific functions. cDNA from Mac-T cells induced in vitro into lactation for 36h (addition of prolactin) was directly hybridize in the microarray chip with cDNA from mammary tissue at -30 or 60 day in milk from 3 cows.

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.
