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.

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

Transcriptome analysis of long non-coding RNAs in Mycobacterium avium complex-infected macrophages

Project description:Mycobacterium avium complex (MAC) is a non-tuberculosis mycobacteria widely distributed throughout environment. Even though the MAC infection is currently increasing in old women and patients with affected immune system, comprehensive analysis of MAC-infected host cell transcriptome, in particular that of long non-coding RNAs (lncRNAs), has scarcely been reported. Using in vitro cultured primary mouse bone marrow-derived macrophages (BMDMs) and CAGE technology, we analyzed the transcriptional and kinetic landscape of macrophage genes, with focusing on lncRNAs, during MAC infection. MAC-infected macrophages induced immune/inflammatory response genes and other genes as similar as M1 activation, consistent with previous reports, although Nos2 and Arg1 revealed distinct expression profiles from M1 activation. We identified 31 up-regulated and 30 down-regulated lncRNA promoters corresponding to 18 and 27 lncRNAs, respectively. The up-regulated lncRNAs were clustered into two groups, early and late up-regulated groups, which were predicted to associate with the immune activation and the immune response to infection, respectively. Further, the Ingenuity IPA analysis predicted canonical pathways and upstream transcription regulators associated with differentially expressed lncRNAs. Several differentially expressed lncRNAs that have been reported elsewhere revealed various expressional change by M1 or M2 pre-activation and the following MAC infection. Finally, we showed that expressional change of lncRNAs in MAC-infected BMDMs is predominantly mediated by Tlr2, but there may be other weakly sensing mechanism for MAC infection. Taken together, we identified differentially expressed lncRNAs in MAC-infected BMDMs, which revealed diverse features implying their distinct role in MAC infection and macrophage polarization.

Gsα regulates macrophage foam cell formation during atherosclerosis

Project description:To investigate in vivo transcriptome profiles of macrophages from CTR and Mac-GsαKO mice , we isolated and cultured peritoneal macrophages. Our data indicates that macrophages from CTR and Mac-GsαKO mice show different mRNA expressions. Compared with macrophages from CTR mice, macrophages from Mac-GsαKO mice expressed more genes related to lipid metabolism.

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 manufacturer’s instructions.

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

Project description:The terminal stage in 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.
