View SamplesIn order to gain insights into how PPARg regulates different facets of dendritic cell (DC) differentiation, we sought to identify PPARg regulated genes and gene networks in monocyte-derived dendritic cells using global gene expression profiling. We employed an exogenous ligand activation approach using a selective PPARg ligand (rosiglitazone abbreviated as RSG). In addition, we have defined culture conditions in which human serum (HS) induces PPARg activation via a yet uncharacterized endogenous mechanism. We also compared the gene expression profile of developing dendritic cells obtained from patients harboring dominant negative mutations of the PPARg receptor (C114R and C131Y).
PPARgamma regulates the function of human dendritic cells primarily by altering lipid metabolism.

View SamplesHuman CD14 positive monocytes were purified from healthy volunteers blood and cultured in vitro for 4, 12, 24, 72 hours. While culturing, macrophages were activated alternatively with interleukin-4 (IL-4 100 ng/ml) or classically with interferon-gamma (IFNg 100 ng/ml)+tumor necrosis factor (TNF 50 ng/ml) or left without activation. Simultaneously, macrophages were also treated with vehicle (DMSO:ethanol) or 1mM synthetic PPARg agonist, Rosiglitazone. We used Affymetrix microarrays (U133Plus 2.0) to analyze activation and PPARg-induced gene expression changes.

View SamplesDifferentiating human dendritic cells were stimulated for 12 hours with RXR agonists (LG268, 9CRA, R- and S-9CDHRA) or agonists for RXR partners including GW3965 (LXR/ panagonist), RSG (PPAR agonist), and GW1516 (PPAR agonist) and AM580 (RARa agonist). The gene expression changes were detected globally by Affymetrix Human Genome U133 Plus 2.0 Arrays.

View SamplesCD14+ human monocytes differentiating into DCs in the presence of IL4 and GM-CSF were treated with agonists for RXR and its partners or vehicle 18 hours after plating (experiment with RXR and permissive partners, donor 1-3) or 14 hours after plating (experiment with nonpermissive partners, donor 4-6). Cells were harvested 12 hours thereafter. Experiments were performed in biological triplicates representing samples from three different donors.
