Bulk RNA-seq on unstimulated and LPS-stimulated human macrophages

ABSTRACT: The goal of this experiment is to profile LPS-stimulated transcriptome changes in human macrophages. Human whole blood was from the Sanofi in-house blood donor service that is approved by the local ethics committee and all blood donors signed informed consent. Human peripheral blood monocytes were isolated from anonymous donors’ prefinal blood using Ficoll density centrifugation, followed by magnetic separation with positive selection (CD14 MicroBeads, Miltenyi Biotec). Monocytes were differentiated into macrophages by culturing in macrophage serum-free medium (Life Technologies) containing 50 ng/ml recombinant human macrophage colony-stimulating factor (Immunotools) for 5 days. Following differentiation, cells were cultured in RPMI 1640 medium supplemented with 10% heat inactivated fetal bovine serum (Thermo Fisher) and maintained at 37°C in a 5% CO2/air environment. Macrophages were stimulated with 50 ng/ml lipopolysaccharides from Escherichia coli O111:B4 (Sigma) for 24 hours.

Transcriptional effects of activation stimuli on M-CSF-derived macrophages

Project description:Analysis of the effect of various activation stimuli on the transcriptional signature of human M-CSF-dependent monocyte-derived macrophages. Methods: Human Peripheral Blood Mononuclear Cells (PBMC) were isolated from buffy coats from donors over a Lymphoprep gradient according to standard procedures. Monocytes were purified from PBMC by magnetic cell sorting using anti-CD14 microbeads (>95% CD14+ cells). Monocytes from three independent donors (0.5 x 106 cells/ml, >95% CD14+ cells) were cultured in RPMI 1640 supplemented with 10% fetal bovine serum (FBS) at 37°C in a humidified atmosphere with 5% CO2 and 21% O2 for 7 days in the presence of 10 ng/ml M-CSF, with cytokine addition every two days. After 7 days, macrophages were either untreated (CNT) or treated with 10 ng/ml E. coli 055:B5 lipopolysaccharide (LPS), 100 ng/ml of the TLR7 agonist CL264 (CL), BSA or 200 mM palmitate (PAL) for 0.5h, 2h, 4h or 12h.

Project description:Analysis of the role of transcriptions factors MAF and MAFB on the phenotypic profles of human M-CSF-derived macrophages. Methods: Human Peripheral Blood Mononuclear Cells (PBMC) were isolated from buffy coats from donors over a Lymphoprep gradient according to standard procedures. Monocytes were purified from PBMC by magnetic cell sorting using anti-CD14 microbeads (>95% CD14+ cells).

Macrophages were differentiated from peripheral blood monocytes from 3 healthy donors with M-CSF (M-MØ) to generate anti-inflammatory M-MØ. Macrophages were transfected with either Control siRNA or MAFB-specific siRNA or MAF-specific siRNA for 24h and global gene expression was analysed by RNA-Seq.

Then, monocyte-derived macrophages were treated with an anti-IL-10 blocking antibody (anti-IL10) or an isotype-matched antibody (IgG2b) at 2.5 micrograms/ml for 1 hour, and exposed to LPS (10 ng/ml). After 4 hours of LPS treatment, cells were lysed and RNA isolated for transcriptional analysis.

The immunomodulatory effects of soluble receptor of activated nuclear factor kappa ligand (sRANKL) on monocyte-derived macrophages

Project description:To explore the effects of sRANKL on tumor-associated macrophages, we first sorted CD14+ monocytes from peripheral blood mononuclear cells of healthy donors using magnetic-activated cell sorting and then induced their differentiation into macrophages by culture with M-CSF for 5 days. We then stimulated these macrophages with IL-4 (20 ng/ml) together with or without 100 ng/ml of sRANKL for 6 hours and examined gene expression using a cDNA microarray.

Transcription profiling of human synovial macrophages from rheumatoid arthritis patients

Project description:Macrophages from RA synovial fluids were compared to primary human blood-derived macrophages. Experiment Overall Design: Macrophages from synovial fluids of five RA patients were isolated by ficoll density gradient centrifugation, followed by positive selection of CD14+ cells using magnetic beads. The patientsâ?? diagnoses were determined by their physicians, in each case a Board-certified rheumatologist at the Hospital for Special Surgery, and were definite RA according to American College of Rheumatology criteria. De-identified samples were processed in an anonymous manner using a protocol approved by the Institutional Review Board of the Hospital for Special Surgery. Experiment Overall Design: Human peripheral blood mononuclear cells were isolated from venous blood of independent healthy donors by centrifugation on a Ficoll density gradient. Monocytes were obtained from PBMCs using anti-CD14 magnetic beads, and were >96% pure as verified by flow cytometry. Monocytes were differentiated into macrophages by culturing in RPMI 1640 medium supplemented with 10% fetal bovine serum and M-CSF (20 ng/ml). The viability and purity of macrophages was comparable in all conditions Experiment Overall Design: Gene expression was analyzed using Affymetrix microarrays and protocols.

Expression data from human macrophages

Project description:Human CD14 positive monocytes were purified from healthy volunteers’ blood and cultured in vitro for 4, 12, 24, 72 hours. While culturing, macrophages were activated alternatively with interleukin-4 (IL-4 100 ng/ml) or classically with interferon-gamma (IFNg 100 ng/ml)+tumor necrosis factor (TNF 50 ng/ml) or left without activation. Simultaneously, macrophages were also treated with vehicle (DMSO:ethanol) or 1mM synthetic PPARg agonist, Rosiglitazone. We used Affymetrix microarrays (U133Plus 2.0) to analyze activation and PPARg-induced gene expression changes. Monocytes from 3 donors were used and treated as indicated in Summary.

RNA samples were isolated using TriPure isolation reagent (Roche) and the RNeasy Mini Kit-Qiagen Clean up method. The transcriptional profile was evaluated in two independent cell preparations, each derived from a different single donor using the HT12 V4 R2 bead chip arrays from Illumina.

In vitro polarization of primary human blood derived macrophages

Project description:Purpose: Generate a benchmark to assess extent of macrophage polarization in disease or infection models. Method: Monocytes were isolated from blood donors who gave informed written consent (Ethics approval number: 161/17, Philipps University Marburg, Germany) by MACS CD14 positive selection. Monocytes were cultured for 7 days in the presence of 1% human off-the-clot AB serum. On day 7, macrophage morphology was assessed by microscope, and cells were left untreated (ctrl), stimulated with 100ng/ml LPS + 20 ng/ml IFNgamma (M1) or 20 ng/ml IL4 + 20 ng/ml IL-13 for 18h. Additionally, a separate set of cells was infected with Legionella Pneumophila Corby wild type and flagellin deficient at MOI1 for 18 h. Then RNA was isolated by phenol chloroform extraction, sample quality was assessed by Bioanalyzer, and samples with a RNA integrity > 8 were sequenced on an Illumina HiSeq 1500.
