In the central nervous system inflammation is mediated by microglia and astrocytes. To investigate its regulation, murine astrocyte cultures were treated with bacterial lipopolysaccharides (LPS) and analyzed with Affymetrix gene array, qRT-PCR and ELISA. Cells responded to LPS with a strong upregulation of proinflammatory cytokines and chemokines. Treatment with the transcriptional activator retinoic acid (RA) suppressed mRNA expression and protein release of several important cytokines (IL-1 beta 4%, IL-6 21%, TNF alpha 30%, IL-12p40 42%, and IL-12p35/p40 27%; p<0.01). The data are consistent with the hypothesis that all-trans RA takes part in endogenous anti-inflammatory feedback loops in the CNS. (C) 2010 Elsevier B.V. All rights reserved.
