Project description:We used microarrays to detail the global programme of gene expression underlying Polo-like kinase inhibition with BI 2536 compound in mouse bone marrow-derived dendritic cells (BMDCs) stimulated with Toll-like receptor agonists LPS and poly(I:C). CD11c+ BMDCs were treated for 1 hour with BI 2536 (1µM) or vehicle control (DMSO) prior to stimulation with LPS or poly(I:C) for 4 h. Total RNA was extracted and prepared for hybridization on Affymetrix microarrays.
Project description:Nitidine Chloride(NC) were found to enhance IL-10 production in LPS-stimulated Bone-marrow dendritic cells(BMDCs ) ,while at the same time inhibit pro-inflammatory cytokines production, such as TNF- α and IL-6. BMDCs were treated with NC or vehicle following LPS stimulation to find out the influence of NC on BMDCs that regulate cytokines expression. This study indicated that NC regulate numerous gene expression, thus influence IL-10 and pro-inflammatory cytokines production in LPS-treated BMDCs.

Project description:Cultured BMDCs were purified by FACS sorting for PDL2 surface expression and stimulated with LPS at 100 ng/mL or left unstimulated. Microarray data was used to demonstrate gene expression differences between PDL2- and PDL2+ DC populations. Microarray data was also used to show that PDL2+ mature DCs were distinct from LPS treated DCs.

Project description:With our experiments we have shown LP(Lactobacillus plantarum) mediated modification of immunogenic bone marrow derived dendritic cells (BMDCs) to acquire tolerogenic phenotype, to unravel the molecular mechanism of LP mediated immunomodulation we performed global transcriptomic Gut of old mice was reconstituted with LP, and RNA was extracted from LPS stimulated BMDCs from young, young treated with antibiotic cocktail, old and old-LP groups for gene array profiling by Agilent GeneChips.
Project description:Purpose: The goals of this study are to compare the different functions of manganese (II) and LPS on the activation and maturation of antigen presenting cells-BMDCs. Methods: BMDCs were generated by culturing bone marrow cells with 20 ng/ml of IL-4 (Genscript) and 20 ng/ml of GM-CSF (Genscript) at 37°C and 5% CO2 for 7 days.Then BMDCs were treated with MnCl2 (200 μM) or LPS (100 ng/ml) for 20 h. Then mRNAs were purified, sequenced and analyzed. Results: Using an optimized data analysis workflow, we compared 20339 transcripts in BMDCs. Manganese (II) induced 1677 transcripts expression with a fold change ≥1.5 and LPS induced 1555 transcripts expression with a fold change ≥1.5. Conclusion: Manganese (II) activates the production of type I IFNs and the maturation of BMDCs. But there are also some differences between functions of manganese (II) and LPS on BMDCs.
Project description:Gene expression was compared between CD11c+ bone marrow derived dendritic cells (BMDC) was compared between cells conditioned in 20nM 1,25(OH)2D3 (Vitamin D) or vehicle. A second analysis compared gene expression in 1,25(OH)2D3 or vehicle CD11c+ BMDCs which were matured in presence of 0.1ug/ml LPS.
Project description:To detect miRNA targets in glioblastoma cell line (BV-2) we stimulate the cells with LPS 10ng/ml or vehicle and then transfect them with miRNA mimics or scrable control We performed differentially expression analysis of RNA-seq BV-2 cells vehicle or LPS stimulated overexpressing miRNA mimic or scramble mimic
