Project description:Macrophages possess the hallmark feature of plasticity, allowing them to undergo a dynamic transition between M(LPS+IFN-γ) and M(IL-4) polarized phenotypes. The aim of the present study was to screen for differentially lncRNAs that were associated with macrophage polarization. The lncRNA profiles of three M(LPS+IFN-γ) and three M(IL-4) samples were obtained using microarray analysis. Based on the threshold of fold-change >2.0 and a p-value < 0.05, we screened a total of 1,251 lncRNAs, of which 627 were upregulated and 624 downregulated in M(LPS+IFN-γ) macrophages compared to that in M(IL-4) macrophages.This study provides new insights into the role of genes in macrophage differentiation and polarization.

Project description:Macrophages possess the hallmark feature of plasticity, allowing them to undergo a dynamic transition between M1 and M2 polarized phenotypes. The aim of the present study was to screen for differentially expressed genes (DEGs) that were associated with macrophage polarization. The transcription profiles of three M1 and three M2 samples were obtained using microarray analysis. Based on the threshold of fold-change >2.0 and a p-value < 0.05, we screened a total of 1,253 DEGs, of which 696 were upregulated and 557 downregulated in M1 macrophages compared to that in M2 macrophages. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were also performed. A gene-gene interaction network of the DEGs was constructed using the STRING database. GO annotation identified three categories, which included cellular component (CC), molecular function (MF), and biological process (BP), with 34 and 40 enrichment terms consisting of upregulated and downregulated DEGs, respectively. GO enrichment analysis of DEGs was mainly associated with protein binding, response to stimulus, cell differentiation, and regulation of biological process. KEGG enrichment identified 15 and four pathways involving upregulated and downregulated DEGs, respectively. Signaling pathway analysis showed that these DEGs were mainly involved in apoptosis, HIF-1 signaling pathway, innate immune system, TNF signaling pathway, cytokine-cytokine receptor interaction, and other signal transduction pathways. Interaction network analysis indicated that Tnf, Il6, Il1b, Socs3, Nos2, Hif1a, and other genes may play key roles in macrophage polarization. This study provides new insights into the role of genes in macrophage differentiation and polarization.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to evaluate the gene expression of M1-polarized RAW264.7 cells compared with M0 RAW264.7 cells. Methods: RAW264.7 cells were polarized toward M1 using LPS and IFN-γ. M0 RAW264.7 cells were maintained in culture without LPS and IFN-γ. Total RNA of M1 and M0 RAW264.7 cells was extracted. RAW264.7 cells RNA profiles were generated by deep sequencing for two groups (M1 versus M0 RAW264.7 cells) with three samples each. Results: There were significant differences between M1 and M0 RAW264.7 cells. Conclusions: Polarization of RAW264.7 cells from M0 to M1 induces various changes at the transcription level.

Project description:CD14+ cells were used to obtain M1 or M2-MDMs in presence of recombinant human IFN-λ3 or IFN-λ4. Briefly, four Caucasian donors (n=4; one female and three males) in between 31-41 y of age, were used to obtain highly homogenous CD14+ cells; these were purchased from a commercial source. The CD14+ cells were incubated with GM-CSF (for M1-MDM) or M-CSF (for M2-MDM) in presence or absence of IFN-λ3 (at 50 ng/ml) or IFN-λ4 (at 6 μg/ml) for six days, and then the cells were fully washed off any residual growth factors or IFNs. After six days of differentiation, the macrophages were matured with LPS for 24 h, then the total cellular RNA was isolated and RNA-seq was performed at QuickBiology, Psadena, CA, USA Summary of the study: Type III interferons or IFN-λs have emerging roles beyond antiviral defense at barrier surfaces. IFN-λ3 and IFN-λ4 are genetically associated with several infectious and inflammatory diseases; however, strong linkage at the IFNL locus circumvents a clearer understanding of their differential influence on the disease phenotypes. Comparative studies to examine the effect of IFN-λ3 and IFN-λ4 on immune cells are lacking. In this study, we used human CD14+ monocytes differentiated into macrophages (MDMs) in presence of IFN-λ3 or IFN-λ4 under M1 or M2 conditions, and after maturation with lipopolysaccharides, to perform RNA-seq analysis in order to understand the changes in molecular phenotypes that may have been induced by the two IFN-λs. Firstly, we found that IFN-λ4 can induce several genes, both unique and common to those induced by IFN-λ3, especially in M1-MDMs; our analysis showed that close to 870 genes (in both cell types) were reciprocally regulated by IFN-λ3 and IFN-λ4. Secondly, the induction of differentially expressed gene pattern suggested that IFN-λ3 has a stronger effect on M2-MDMs compared to M1-MDMs while the reverse is true for IFN-λ4.

Project description:To understand the molecular signature of the IL-10/IL-18 polarized macrophages, we performed transcriptome analysis for mouse BMDMs polarized with PBS (Naïve), IFN-γ (classic M1 stimulator, M1, 20ng/ml), IL-4 (alternative M2 stimulator, M2, 20ng/ml), IL-10 (M10, 2000ng/ml), IL-18 (M18, 2000ng/ml) or IL-10 and IL-18 (M1018, 2000ng/ml each). These data suggest that IL-10 and IL-18 cooperatively modulate a set of gene expressions and pathway activities in macrophages and contribute to a distinct polarization state.

Project description:Pattern recognition receptors (PRR) detect microbial products and induce cytokines which shape the immunological response. Interleukin-12 (IL-12), tumor necrosis factor alpha (TNF-α) and IL-1β are proinflammatory cytokines which can be essential for resistance against infection, but if produced at high levels, may contribute to immunopathology. In contrast, IL-10 is an immunosuppressive cytokine which dampens proinflammatory responses, but can also lead to defective pathogen clearance. The regulation of these cytokines is therefore central to the generation of an effective but balanced immune response. Here, we show that macrophages derived from C57BL/6 mice produce low levels of IL-12, TNF-α and IL-1β, but high levels of IL-10 in response to TLR4 and TLR2 ligands LPS and PamCSK4, and Burkholderia pseudomallei a Gram-negative bacterium which activates TLR 2/4. In contrast, macrophages derived from BALB/c mice show a reciprocal pattern of cytokine production. Differential production of IL-10 in B. pseudomallei and LPS stimulated C57BL/6 and BALB/c macrophages was due to a type I IFN dependent, but IL-27 independent mechanism. Further, type I IFN contributed to differential IL-1β and IL-12 production in B. pseudomallei and LPS stimulated C57BL/6 and BALB/c macrophages, via both IL-10-dependent and independent mechanisms. These findings highlight key pathways responsible for the regulation of pro- and anti-inflammatory cytokines in macrophages and reveal how they may differ according to the genetic background of the host. Total RNA obtained from bone-marrow derived macrophages of C57BL/6 WT, C57BL/6 Ifnar1-/- and BALB/c mice stimulated with heat-killed Burkholderia pseudomallei or media as controls.
