Project description:Bone marrow cells (BM) were isolated and primed with M-CSF (M BMDM) or GM-CSF (GM BMDM) for 7 days. M-BMDMs were treated with IL6 (20 ng/ml) for 3 h or 24 h while GM-BMDMs were treated for 3 h. The difference between BM, M-BMDM, and GM-BMDM were analyzed to describe the phenotye and function of each population. Moreover, by RNA-seq analysis, the influence of IL6 treatment on GM-BMDMs and M-BMDMs were analyzed.

Project description:Bone marrow cells were isolated, primed with M-CSF (M BMDM) or GM-CSF (GM BMDM) and cultured on tissue culture dishes (TC) or low adherent dishes (noTC) for 7 days. BMDMs were treated with LPS (100 ng/ml) for 3 hours. The difference between TC- and noTC-cultured BMDMs were analyzed to describe the phenotye and function of each population. Moreover, the influence of LPS treatment on GM-BMDMs and M-BMDMs were analyzed.

Project description:Bone marrow-derived macrophages (BMDMs) are a key model system for studying macrophage biology in vitro. Commonly used methods to differentiate macrophages from bone marrow are treatment with either recombinant M-CSF or the supernatant of L929 cells, which secrete M-CSF. However, little is known about the composition of L929 conditioned media (CM) and how it affects BMDM phenotype. Here, we used quantitative mass spectrometry to characterise the kinetics of protein secretion from L929 cells over a two-week period. While M-CSF is very abundant in L929 CM, we identified several other immune-regulatory proteins at surprisingly high abundance. L929 CM induced a slightly pre-activated phenotype and the expression of a number of known innate immune proteins in macrophages. This resource will be valuable to all researchers using L929 CM for the differentiation of BMDMs.

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 M2-polarized bone marrow-derived macrophages (BMDM) compared with M0-BMDMs from wild type (WT) mouse. Methods: BMDMs were obtained from WT mice and polarized toward M2-BMDMs using IL-4 and M-CSF. M0-BMDMs were maintained in culture with M-CSF only. Total RNA of M2- and M0-BMDMs was extracted. BMDM RNA profiles were generated by deep sequencing for two groups (M2- versus M0-BMDM) with three mouse samples each. Results: There were significant differences between M2- and M0-BMDMs. Conclusions: Polarization of BMDMs from M0 to M2 induces various changes at the transcription level.

Project description:Bone marrow cells were isolated, primed with M-CSF (M-BMDM) or GM-CSF (GM-BMDM) and cultured for 7 days. The proteomic difference between GM-BMDM and M-BMDM were analyzed to describe the phenotye and function of two types of macrophages.

Project description:OASL1 is a novel translation inhibitor for the type I IFN master transcription factor IRF7. To examine whether OASL1 specifically inhibit IRF7 translation, we used a genome-wide gene expression microarray to screen for the polysome-associated mRNAs more enriched in the OASL1 KO BMDMs. The microarray analysis on the polysomal fractions identified 145 candidate transcripts, including IRF7, that showed a signal greater than two-fold higher in poly(I:C)-treated Oasl1-/- BMDM. We analyzed polysomal fractions from poly(I:C)-treated WT and Oasl1-/- BMDM using the Affymetrix Mouse Gene 1.0 ST array. Array data were processed by Affymetrix GCOS software. We compared these using Affymetrix Expression console1.1, R affy-package(2.9.2), DAVID.

Project description:Purpose: Mouse BMDM is the universal cell type of studying innate immunity.This study was designed to analyze LPS induced innate immune respone and the gene expression in WT and HDAC3 KO BMDMs. Methods: BMDM cells from Hdac3f/f and Lyz2-Cre-Hdac3f/f were treated with or without LPS for 4 hours. Then mRNA profiles of these samles were generated by High-throughput sequencing analysis, in triplicate, using illumina HiSeqTM2000/MiSeq. And the differencial mRNA profiles were analyzed. Results: mRNA profiles were analyzed, and differencial expression profiles were compared . Conclusions: Our study demostrated the transcriptional profiles of BMDMs from Hdac3f/f and Lyz2-Cre-Hdac3f/f mice upon LPS challenge, with biologic replicates, generated by RNA-seq technology.

Project description:Mouse bone marrow-derived macrophages (BMDM) grown in macrophage colony-stimulating factor (CSF-1) have been used widely in studies of macrophage biology and the response to toll-like receptor agonists. We investigated whether similar cells could be derived from the domestic pig. Cultivation of pig bone marrow cells for 5-7 days in presence of rhCSF-1 generated a pure population of BMDM that expressed the usual macrophage markers (CD14, CD16, CD163, CD172a), are potent phagocytic cells and produced tumor necrosis factor (TNF) in response to lipopolysaccharide (LPS). Bone marrow cells could be stored frozen and thawed, providing a renewable resource. We profiled gene expression in pig BMDM from outbred animals (Large-White Landrace F1cross) responding to LPS using Affymetrix microarrays. The temporal cascade of inducible and repressible genes more closely-resembled human than mouse macrophages, and included genes involved in tryptophan metabolism (IDO, KYN), lymphoattractant chemokines (CCL20) and the vitamin D3-converting enzyme Cyp27B1. Conversely, pig BMDM, like human macrophages, did not induce genes involved in arginine metabolism, nor did they produce nitric oxide. The data establish pig BMDM as an alternative tractable model for the study of macrophage transcriptional control. RNA for gene expression analysis was collected at time points 0, 2, 7 and 24 hours post LPS stimulation (100ng/ml). Each time point included BMDM from the same three pigs and each cell culture was replicated. The replicate of the pig3_24h was not suitable for RNA analysis. Therefore, a total of 23 microarrays were hybridized.

Project description:<p>Macrophages play a critical role in the inflammatory response and tumor development. Macrophages are primarily divided into pro-inflammatory M1-like and anti-inflammatory M2-like macrophages based on their activation status and functions. <em>In vitro</em> macrophage models could be derived from mouse bone marrow cells stimulated with two types of differentiation factors: GM-CSF (GM-BMDMs) and M-CSF (M-BMDMs), to represent M1-and M2-like macrophages, respectively. Since macrophage differentiation requires coordinated metabolic reprogramming and transcriptional rewiring in order to fulfill their distinct roles, we combined both transcriptome and metabolome analysis, coupled with experimental validation, to gain insight into the metabolic status of GM-and M-BMDMs. The data revealed higher levels of the tricarboxylic acid cycle (TCA cycle), oxidative phosphorylation (OXPHOS), fatty acid oxidation (FAO), and urea and ornithine production from arginine in GM-BMDMs, and a preference for glycolysis, fatty acid storage, bile acid metabolism, and citrulline and nitric oxide (NO) production from arginine in M-BMDMs. Correlation analysis with the proteomic data showed high consistency in the mRNA and protein levels of metabolic genes. Similar results were also obtained when compared to RNA-seq data of human monocyte derived macrophages from the GEO database. Furthermore, canonical macrophage functions such as inflammatory response and phagocytosis were tightly associated with the representative metabolic pathways. In the current study, we identified the core metabolites, metabolic genes, and functional terms of the two distinct mouse macrophage populations. We also distinguished the metabolic influences of the differentiation factors GM-CSF and M-CSF, and wish to provide valuable information for <em>in vitro</em> macrophage studies. </p>
