Comparative gene expression in response to various inflammatory stimuli in vitro: infection-mediated versus systemic inflamamtion. Comparative gene expression in response to various inflammatory stimuli in vitro: infection-mediated versus systemic inflamamtion

To unedrstand the global gene expression profile depending upon origin of inflammation, we have employed microarray analysis in vitro. We have treated THP-1 macrophage like cells with TNFα, IL-6 to mimic inflammatory milieu similar to systemic inflammation while bacterial LPS treatment represented for infectious inflammation. Overall design: THP-1 macrophage like cells were treated with TNFα (10 ng/ml), IL-6 (50 ng/ml) and LPS (100 ng/ml) for 2 hours. Cells were treated with PBS served as control
