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:ATAC-seq profiling of Nfat5 KO and wild type macrophages derived from bone marrow (primary cells), treated or not with Lipopolysaccharide (LPS).
Project description:This is an investigation of whole genome gene expression level in tissues of mice stimulated by LPS, FK565 or LPS + FK565 in vivo and ex vivo. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in aortic root including aortic valves, slight in aorta and absent in other arteries. The degree of respective vascular inflammation is associated with persistent high expression of proinflammatory chemokine/cytokine genes in each tissue in vivo by microarray analysis, and not with Nod1 expression levels. The ex vivo production of proinflammatory chemokine/cytokine by Nod1 ligand is higher in aortic root than in other arteries from normal murine vascular tissues, and also higher in human coronary artery endothelial cells (HCAEC) than in human pulmonary artery endothelial cells (HPAEC), suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular tissue/cell itself. A fourty chip study using total RNA recovered from four isolated tissues of mice which were stimulated by various reagents. Aortic root, pulmonary artery, aorta and spleen of mice in 3 groups: 1) intraperitoneal injection of 20M-NM-<g of LPS priming only, 2) oral administration of FK565 (100M-NM-<g) for consecutive days, 3) oral administration of FK565 (100M-NM-<g) for consecutive days 1 day after LPS priming, at day 2, 4, and 7. And six chip study using total RNA recovered from three isolated vascular tissues of mice which were stimulated by FK565 (10M-NM-<g/mL) ex vivo.
