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. Experiment Overall Design: Human monocytes were obtained from buffy coats from healthy donors by Ficoll gradient centrifugation followed by immunomagnetic cell separation with anti-CD14-conjugated microbeads. Monocytes were cultured in RPMI-1640 supplemented with 10% FBS, 800 U/ml GM-CSF and 500 U/ml IL-4. 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. Experiments were performed in biological triplicates representing samples from different donors. 15 samples were processed and hybridized to Human Genome U133 Plus 2.0 Arrays.

Project description:To investigate the effect of MGL ligation in monocyte-derived dendritic cell biology, we generated control dendrimers and two different glycodendrimers exposing the MGL ligands αGalNAc or GalNAcβ1-4Gal. αGalNAc and GalNAcβ1-4Gal glycodendrimers were validated in the corresponding manuscript. Monocyte-derirved dendritic cells were generated by culturing monocytes for 4 days with IL-4 and GM-CSF. To study the effect of MGL-ligation at the transcriptional level, next generation sequencing was performed on monocyte-derived dendritic cells from three independent donors, stimulated for 4 h with control, αGalNAc or GalNAcβ1-4Gal glycodendrimers in the absence or presence of LPS.

Project description:To evaluate the DC genome-wide gene expression in response to beta-glucan and its regulation by IL-1 receptor antagonist (IL-1RA) we used a whole genome microarray. The gene expression profiling was performed in DC left untreated or exposed to beta-glucan for 4 and 12 h, in absence or presence of IL-1RA. This strategy allowed the identification of early/immediate and late/secondary genes regulated by beta-glucan in an IL-1-dependent and -independent manner. Human monocyte-derived DC were obtained by a 6/7-d cultures of freshly isolated monocytes with recombinant human IL-4 (10 ng/ml) and GM-CSF (50 ng/ml).

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.
