Gene expression in IRF3-/- peritoneal macrophage infected with VSV


ABSTRACT: IRF3 is one of the most critical transcription factor in down stream of pattern recognition receptors (such as toll-like receptor and RIG-I-like receptor) signalling pathway. IRF3 is known to induce the expression of type I IFN gene upon virus infection. To furter examine the role of IRF3 in virus-induced gene expression, we preformed microarray analysis in IRF3-/- peritoneal macrophages infected with VSV, and found that IRF3 suppresses the expression of Il12b gene. Peritoneal macrophages from WT of IRF3-/- B6 mice were infected with VSV(1 M.O.I. ) for 6 hous, and then subjected to microarray analysis.

Although the mechanisms by which innate pathogen-recognition receptors enhance adaptive immune responses are increasingly well understood, whether signaling events from distinct classes of receptors affect each other in modulating adaptive immunity remains unclear. We found here that the activation of cytosolic RIG-I-like receptors (RLRs) resulted in the selective suppression of transcription of the gene encoding the p40 subunit of interleukin 12 (Il12b) that was effectively induced by the activ  ...[more]
