Transcription profiling of mouse wild-type, TBK1, IKKi(Ikbke), or TBK1 IKKi doubly deficient embryonic fibroblats to elucidate how TBK1 and/or IKKi mediates B-DNA-mediated innate immune responses

ABSTRACT: B-DNA-induced gene expression profile in wild-type, TBK1, IKKi(Ikbke), or TBK1 IKKi doubly deficient embryonic fibroblats; to elucidate how TBK1 and/or IKKi mediates B-DNA-mediated innate immune responses. Experiment Overall Design: Total RNA was extracted from embryonic fibroblats transfected for 4 h with or without poly(dA-dT)-poly(dT-dA), after which cRNA was synthesized. Preparation of cRNA, hybridization and scanning of the microarray were done according to the manufacturer's instructions (Affymetrix). A microarray (MG U74A version 2; Affymetrix) was used with Microarray Suite software (version 5.0; Affymetrix) and GeneSpring software (Silicon Genetics).

The innate immune system recognizes nucleic acids during infection or tissue damage; however, the mechanisms of intracellular recognition of DNA have not been fully elucidated. Here we show that intracellular administration of double-stranded B-form DNA (B-DNA) triggered antiviral responses including production of type I interferons and chemokines independently of Toll-like receptors or the helicase RIG-I. B-DNA activated transcription factor IRF3 and the promoter of the gene encoding interferon  ...[more]
