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

ABSTRACT: 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

IL-27, a member of the IL-12 family of cytokines, plays an important and diverse role in the function of the immune system. Whilst generally recognized as an anti-inflammatory cytokine, in addition IL-27 has been found to have broad anti-viral effects. Recently, IL-27 has been shown to be a potent inhibitor of HIV-1 infection in CD4+ T cells and macrophages. The main objective of this study was to see whether IL-27 has a similar inhibitory effect on HIV-1 replication in dendritic cells (DCs). Mo ...[more]

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.

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

Project description: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.

Gene expression of murine iDCs isolated from tolerized MOG35-55-infused/MOG35-55-immunized or MOG35-55-immunized mice

Project description:Recent data from our group, demonstrate that infusion of myelin oligodendrocyte glycoprotein (MOG35-55) peptide, leads to induction of MOG35-55-specific Tregs and subsequent suppression of Experimental Autoimmune Encephalomyelitis (EAE), the mouse model of multiple sclerosis. Amelioration of EAE was accompanied by reduced MOG-specific Th1 and Th17 responses in the draining lymph nodes (dLNs). Phenotypic analysis of the dLNs of MOG-infused mice revealed a significant Treg-mediated reduction in the recruitment of 7AAD-CD3-CD19-CD11c+CD11bhighGr-1+ iDCs compared to non-infused control immunized mice. Focusing on the delineation of novel molecules/genes that are involved in the MOG-specific Treg-mediated suppression of autoimmune responses, we have isolated highly purified iDCs from MOG infused and non-infused control immunized mice. Gene expression profiles of iDCs isolated from tolerized or immunized mice. Affymetrix MG 430 2.0 whole genome arrays were performed in triplicates for tolerized iDCs and immunized iDCs (6 arrays in total, 5 of them were analyzed). To obtain genes significantly regulated in iDCs upon tolerization with MOG35-55, the expression profiles of iDCs isolated from tolerized or immunized mice were compared to each other. After total RNA extraction, reverse transcription, cDNA extraction, the biotinylated cRNA was transcribed, fragmented, and 15 µg cRNA hybridized to the 6 GeneChip arrays: Group1 iDCs isolated from tolerized mice, Group2 iDCs isolated from immunized mice.

Transcription profiling of human dendritic cells after infection with A. fumigatus

Project description:DCs are localized under the mucosa of the lungs and the gastrointestinal tract, and therefore come into close contact with A. fumigatus germ tubes during early steps of infection as soon as fungi become invasive. For a more detailed insight into differentially regulated genes, whole genome microarray analysis was performed. On average, unstimulated DCs showed expression of about 13.500 genes (35% of all genes spotted on the chip). After 6h co-cultivation of DCs and live A. fumigatus germ tubes, 590 genes showed a 4fold altered gene expression, if normalizing data with VSN before. Therein, a wide range of immune response genes, including genes encoding for cytokines (IL-1Î±, IL-1Î², IL-6, IL-8, IL-10, IL-12p40, TNF-Î±), chemokines (CCL5, CCL20, CXCL10), immunorelevant receptors (TLR2, TLR4, PTX-3), as well as costimulatory molecules (CD40, CD80, CD83, CD86) were differentially regulated. Experiment Overall Design: Human DCs were generated from two independent, healthy blood donors. 5 x 106 DCs were either cultivated without fungi or together with 5 x 106 A. fumigatus germ tubes for 6h until isolation of total RNA.

Transcription profiling by array of dendritic cells from three different human donors to characterize the impact of differential HIV opsonization on dendritic cell modulation

Project description:The aim of this study was to characterize the impact of differential HIV opsonization on DC modulation. DCs are the most potent antigen-presenting cells and among the first cells HIV is attaching to. HIV spontaneously activates the complement system even in the absence of specific antibodies and is therefore found opsonized with complement fragments from the beginning of infection. Gene expression profiles of DCs from three different human donors and treated for 24 hrs with 100 ng/ml LPS, 300 ng/ml non-opsonized HIV (HIV-MC), or 300 ng/ml complement-opsonized (HIV-C) were compared to those of untreated immature DCs.

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.
