Transcriptional effects of LXR nuclear receptors on GM-CSF-derived macrophages

ABSTRACT: Analysis of the role of LXR transcriptions factors on the transcriptional signature of human GM-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 treated with LXR agonist GW3965 (1 uM, Tocris), LXR antagonist GSK2033 (1 uM, Tocris), GW3965 and GSK2033, or dimethyl sulfoxide (DMSO) as vehicle. In the dual condition, the antagonist was added 1-hour prior to agonist treatment. Then, monocytes 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 1000 U/ml GM-CSF, with cytokine addition every two days.

Human CD14+CD16- and CD16+ monocyte-derived macrophages primed by GM-CSF or M-CSF

Project description:Identification of genes differentially expressed between human CD14+CD16- and CD16+ monocyte-derived macrophages generated in the presence of either GM-CSF (termed GM14 and GM16, respectively) or M-CSF (termed M14 and M16, respectively) Human peripheral CD14+CD16- and CD16+ blood monocytes from three independent healthy donors (D1, D2 and D3) were isolated by positive selection from peripheral blood mononuclear cells (PBMC) using magnetic separation systems (MACS, Miltenyi Biotec). Briefly, PBMC were first incubated with MACS anti-CD56 antibody conjugated to paramagnetic microbeads in order to eliminate the NK (CD16+) cell fraction. NK-depleted PBMC were further incubated with MACS anti-CD16 antibody to isolate CD16+ monocytes. CD56-CD16- PBMC were finally incubated with MACS anti-CD14 antibody to obtain the CD14+CD16- monocyte fraction. Monocytes were cultured for 7 days in medium containing either GM-CSF or M-CSF. Total RNA from each condition was extracted using the RNeasy kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

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.
