Project description:Analysis of dendritic cells (DCs) at 6h and 48h after infection with cytomegalovirus (CMV) versus non infected. CMV tends to induce immunosuppression followed by lasting immunity. DCs appear to play a role in this effect. Results provide insights into CMV/DC interactions and suggest mechanisms for CMV-regulated early immune response. Keywords: gene expression array-based, count In the present study, immature monocyte-derived dendritic cells were generated from CMV neg healthy blood donors and infected or not with an endotheliotropic CMV strain. Gene expression modulation by the CMV infection was studied in a time course assay (non-infected - NI - vs 6h or 48h post-infection. Patient C has no 48h sample

Project description:Human cytomegalovirus induces a pro-inflammatory monocyte following infection. To begin to address how HCMV induces these rapid changes in infected monocytes, we examined the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of pro-inflammatory genes were upregulated within 4 hours post infection. Experiment Overall Design: To begin to globally define the HCMV-induced changes in monocyte function, we performed a transcriptome analysis. Specifically, a cDNA microarray containing 12,626 unique probe sets was utilized to assess the modulation of the monocyte transcriptome at 4 hours post infection. A total of 6 replicates from mock-infected and 6 replicates from HCMV-infected monocytes were analyzed in this study.

Project description:We have carried out global gene expression analysis to clarify the interrelationship between 1,25-dihydroxyvitamin D3 and differentiation-driven gene expression patterns in developing human monocyte-derived dendritic cells. Monocytes were treated with 10 nM 1,25-dihydroxyvitamin D3 or vehicle 14 hours after plating for 12 hours or 5 days. Monocytes, differentiating dendritic cells (+/-1,25-dihydroxyvitamin D3 for 12 hours) and immature dendritic cells (+/-1,25-dihydroxyvitamin D3 for 5 days) were harvested. This design allows one to identify genes regulated by differentiation and/or 1,25-dihydroxyvitamin D3 in human monocyte-derived dendritic cells.

Project description:Identification of MEK-ERK or p38MAPK dependent genes in human monocyte derived dendritic cells. Dendritic cells (DC) promote tolerance or immunity depending on their maturation state. Previous studies have revealed that DC maturation is enhanced or accelerated upon MEK-ERK signaling pathway inhibition. We have now determined the contribution of MEK-ERK activation to the profile of gene expression of human immature monocyte-derived dendritic cells (MDDC) and peripheral blood myeloid DC. ERK inhibition altered the expression of genes that mediate CCL19-directed migration (CCR7) and LDL binding (CD36, SCARB1, OLR1, CXCL16) by immature DC. Besides, ERK upregulated CCL2 expression while impaired the expression of DC maturation markers (RUNX3, ITGB7, IDO1). MEK-ERK-regulated genes exhibited an over-representation of cognate sequences for the Aryl Hydrocarbon Receptor (AhR) transcription factor, and we show that AhR mediates some of the ERK-dependent transcriptional effects in DC. Therefore, MEK-ERK signaling pathway regulates antigen capture, lymph node homing and the acquisition of maturation-associated genes, and its contribution to the maintenance of the immature state of MDDC and myeloid DC is partly dependent on the activity of AhR. Since pharmacological modulation of the MEK-ERK signaling pathway has been proposed as a potential therapeutic strategy for cancer, our findings indicate that ERK inhibitors might influence the generation of anti-tumor responses through regulation of critical DC effector functions. Human peripheral blood monocytes from three independent healthy donors (DC4, DC5 and DC7) were isolated by anti-CD14-labeled magnetic microbeads. CD14+ monocytes were cultured for 5 days in RPMI 10% FCS containing GM-CSF and IL-4 to generate immature monocyte-derived dendritic cells (MDDC). Immature MDDC were exposed to MEK inhibitor, U0126, or p38MAPK inhibitor, SB203580 for 1 hour and a final dose of GM-CSF and IL-4 were added to the culture. Cells were collected for analysis after 4, 10 or 24 hours.Total RNA from each condition was extracted using the All prep DNA/RNA/protein mini kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

Project description:Transcriptional profiles of four different myeloid antigen presenting cell (APC) subsets (BDCA-1+ circulating myeloid dendritic cells, CD14+ monocytes, and in vitro generated immature and mature monocyte-derived dendritic cells) were used for comprehensive transcriptome analysis. Based on the gene expression profiling data, a quantitative relationship between myeloid APC in functionally related gene spaces was established.
