Intracellular Cryptococcus neoformans Disrupts the Transcriptome Profile of M1- and M2-Polarized Host Macrophages

Project description:Macrophages serve as a first line of defense against infection with the facultative intracellular pathogen, Cryptococcus neoformans (Cn). However, the ability of these innate phagocytic cells to destroy ingested Cn is strongly influenced by polarization state with classically (M1) activated macrophages better able to control cryptococcal infections than alternatively (M2) activated cells. While earlier studies have demonstrated that intracellular Cn minimally affects the expression of M1 and M2 markers, the impact on the broader transcriptome associated with these states remains unclear. To investigate this, we used an in vitro cell culture model of intracellular infection together with RNA sequencing-based transcriptome profiling to measure the impact of Cn infection on gene expression in both polarization states. The gene expression profile of both M1 and M2 cells was extensively altered to become more like naive (M0) macrophages. Gene ontology analysis suggested that this involved changes in the activity of the Janus kinase-signal transducers and activators of transcription (JAK-STAT), p53, and nuclear factor-κB (NF-κB) pathways. Analyses of the principle polarization markers at the protein-level also revealed discrepancies between the RNA- and protein-level responses. In contrast to earlier studies, intracellular Cn was found to increase protein levels of the M1 marker iNos. In addition, we identified common gene expression changes that occurred post-Cn infection, independent of polarization state. This included upregulation of the transcriptional co-regulator Cited1, which was also apparent at the protein level. These changes constitute a transcriptional signature of macrophage Cn infection and provide new insights into how Cn impacts gene expression and the phenotype of host phagocytes.

miRNA sequencing from exosomes derived from M1-or M2-polarized bone-marrow derived macrophages (BMDMs).

Project description:We reported exosome-guided phenotype switches between M1- and M2-polarized BMDMs. M1- or M2-polarized BMDMs were successfully reprogrammed to M2- or M1-phenotype via the treatment of exosomes obtained from M2- or M1-polarized BMDMs. In this uploaded information, the exosomes from M1- and M2-polarized BMDMs were analyzed by high-throughput sequencing.

Microarray of non-polarized and M1- and M2-polarized canine macrophages in vitro

Project description:Unstimulated (M0), M1-polarized (GM-CSF, LPS, IFNÎ³-stimulated), and M2-polarized (M-CSF, IL-4-stimulated) canine blood-derived macrophages were generated in vitro and investigated for differences in their transcriptome to create a basis for future investigations upon the role of macrophage polarization in dogs, a species, which has emerging importance for translational research.

Expression profiles of M1-polarized RAW264.7 cells [RAW_M1vsM0_RNA-seq]

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.

Gene expression profiles of the M1/M2 polarized Kupffer cells

Project description:To reveal the transcriptomes associated with M1 or M2-polarized Kupffer cells, the primary Kupffer cells isolated from mouse liver were treated with lipopolysaccharides or IL-4 and the gene expression patterns were analyzed by microarray. To study the role of RORα in Kupffer cell polarization, Kupffer cells were treated with RORα ligands and transcriptions were compared with those of the M1/M2 polarized Kupffer cells.

Identification of downregulated microRNA in a gastric cancer cell line co-cultured with M1- or M2-polarized macrophage

Project description:We showed that co-culture with TAMs triggered Bmi1 expression in gastrointestinal cancer cell lines. miRNAs have been found to target various oncogenes and tumor suppressors. We therefore hypothesized that the regulation of Bmi1 expression in gastrointestinal cancer cells may be mediated by miRNAs using miRNA microarray analysis. THP-1 cells were seeded in the transwell inserts (3540, Corning) for 6-well plates (1 M-CM-^W 106 cells/well). For preparation of M1-polarized THP-1 macrophages, 320 nM phorbol myristate acetate (PMA) was added to THP-1 cells for 6 h, followed by PMA plus 20 ng/ml interferon (IFN)-M-NM-3 and 100 ng/ml lipopolysaccharide for the following 18 h. For preparation of M2-polarized THP-1 macrophages, 320 nM PMA was added to THP-1 cells for 6 h, followed by PMA plus 20 ng/ml interleukin (IL)-4/IL-13 for the following 18 h. After three washes to remove cytokines, M1- or M2-polarized THP-1 macrophages were co-cultured in upper inserts with AGS cells in 6-well plates (1 M-CM-^W 105 cells/well) without direct contact, in each medium without 10% FBS as described above. After 24 h of co-culture, the upper inserts containing macrophages were discarded. AGS cells were collected and analyzed to identify downregulated microRNA in a gastric cancer cell line co-cultured with M1- or M2-polarized macrophage.

Genome-wide analysis of M1 and M2 polarized macrophages with CNI-1493 treatment

Project description:Analysis of the effects of CNI-1493 treatment on M1 and M2 polarized macrophages. The purpose of this microarray is to identify genes that may be differentially expressed in M1 or M2 macrophages after treatment with CNI-1493. CNI-1493 is a known inhibitor of M1 macrophages but details of its molecular mechanism are unknown. The effect of CNI-1493 on M2 macrophages has yet to be explored, but we hypothesize that CNI-1493 treatment will attenuate pro-tumor properties of M2 macrophages. We demonstrate with this array that known macrophage markers are unchanged after treatment with CNI-1493, indicating that CNI-1493 does not change the macrophage phenotype on a transcriptional level. Additionally, no candidate genes to suggest how CNI-1493 may attenuate the pro-tumor effects of M2 macrophages are readily identifiable. Total RNA extracted from M1 or M2 macrophages after polarization with GM-CSF (25ng/ml) or M-CSF (25ng/ml) for 7 days, followed by addition of IFN-γ (20ng/ml) and LPS (100ng/ml) or IL-4 (40ng/ml) for 18 hours, respectively, from CD14+ human PBMCs, and treated with CNI-1493 (200nM)

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.
