MicroRNA expression signature of monocyte-derived dendritic cells (DCs) from peripheral blood mononuclear cells (PBMCs)

ABSTRACT: In order to detect the microRNA expression profile of in vitro generated dendritic cells , purified monocytes from PBMCs were used as dendritic cell (DCs) precursors and were cultured in medium with cocktail for differentiation and maturation to immature dendritic cells (iDCs) and mature dendritic cells (mDCs). microRNA samples were isolated from precursor, iDCs and mDCs and used for microarray-based microRNAs expression profiles. To generate enough amount of immature DC (iDCs) and mature DCs (mDCs), monocytes were differentiated with GM-CSF and rhIL-4 for 2 days and maturated in the presence of TNF-α, IL-1β, IL-6 and PGE2 for another 2 days. With the anticipation to insight developmental-stage-specific microRNAs with potential functions related to monocyte derived DCs, global microRNAs expression profiling was set using microarray technology.microRNA expression profiles were performed in triplicate independent experiments starting for 3 groups of precursor, iDC and mDC generated from different blood donors.

Interleukin-27 is a potent inhibitor of cis HIV-1 replication in Monocyte-derived Dendritic Cells via a Type I Interferon-independent pathway

Project description:IL-27 treated DCs were shown to be highly potent inhibitors of cis HIV-1, particularly of CCR5 tropic strains. Microarray studies of IL-27 treated DCs showed no up-regulation of Type I (IFN) gene expression. Neutralization of the Type-I IFN receptor had no impact on the HIV inhibition. Lastly, IL-27 mediated inhibition was shown to act post-viral entry and prior to completion of reverse transcription. These results show for the first time that IL-27 is a potent inhibitor of cis HIV-1 infection in DCs by a Type I IFN independent mechanism. Gene expression microarrays from 3 samples of immature dendritic cells (iDCs) were compared with 3 samples of iDCs treated with IL-27

Inhibition of p38 MAPK in DC progenitor cells endows DCs with superior immunogenicity

Project description:Analysis of the p38 MAPK pathway in regulation of dendritic cells (DCs) differentiation at the gene expression level. Bone marrow cells were cultured with mGM-CSF (20 ng/ml) in the presence of 1.5 mM of SB202190 or 0.1% DMSO. At day 7, semi-adherent cells were collected as immature DCs (iDCs). iDCs were matured by TNF-a (10 ng/ml) and IL-1b (10 ng/ml) for 48 hours. Results showed that p38 MAPK activity in DC progenitor cells acts as an antigen presentation attenuator, and disabling this critical brake during DC differentiation endows DCs with enhanced immunogenicity, which may be useful for the induction of antitumor immune responses. Total RNA was obtained from 2-day-cultured bone marrow cells, iDCs and mature DCs.

Transcription profiling of human dendritic cells treated with Echinacea purpurea phytocompounds

Project description:This study investigated the specific and differential gene expression in human immature DCs (iDCs) in response to treatment with a butanol fraction containing defined bioactive phytocompounds extracted from stems and leaves of Echinacea purpurea Experiment Overall Design: Human immature DCs (iDCs) differentiated from primary monocytes in vitro were incubated with [BF/S+L/Ep] or cichoric acid for 4 or 24 h to characterize early- or late-responsive genes. A total of nine Affymetrix HU-133A chips were hybridized to determine the transcriptome profiles in human iDCs.

Effect of HIV infection on co-stimulatory capacity of dendritic cells

Project description:HIV uses dendritic cells as a carrier to infect its target CD4+ T cells. At the same time, it also hampers DCs function in terms of their T cell stimulatory capacity and cytokine secretion. We have shown that HIV causes reduction in the expression of co-stimulatory molecules, CD80 and CD86 by DCs at the mRNA level irrespective of the viral subtype or the mode in DC-HIV interaction. The microarray experiments were performed to understand the changes in the transcription factor profile of HIV infected DCs which may in turn lead to reduced CD80/CD86 expression as well as the effect of HIV infection on other co-stimulatory molecules on DCs. The data suggests that TFs NFKB1, NFKB2, REL and MYB may be responsible for the observed decrease in CD80 and CD86 expression and that HIV infection also hampers the expression of other co-stimulatory molecules like CD70, CD30, 4-1BB, OX40L etc. The total RNA was isolated from LPS matured DCs (positive control) and HIV infected DCs using Qiagen RNeasy Minikit. Agilent Quick-Amp Labelling kit (p/n 5190-0444) was used to synthesize the labeled cDNA from 3 ug of total RNA and further process the hybridized cDNA on the array. All the steps were carried out according to manufacturerM-bM-^@M-^Ys instructions (www.agilent.com/chem/dnamauals-protocol). The array slides were scanned immediately using high throughput Agilent scanner with SureScan technology. Agilent feature extraction software was used for normalization and statistical analysis,. Pathway and gene ontology analysis was done using Genespring GX v 10.0 and biointerpreter software. The experiments were performed on DCs cultured from two independent donors. The differential expression was considered if the Log 2 mean of at least -1 for the down regulated genes and +1 for the upregulated genes. We considered only the genes that were differentially regulated genes in both the donors.
