Project description:Identification of a FOXO3/IRF7 circuit that limits inflammatory sequelae of antiviral responses (expression)
| PRJNA157893 | ENA
Project description:We predict that a member of the forkhead family of transcription factors, FOXO3, is a negative regulator of a subset of antiviral genes. This prediction was validated using macrophages isolated from Foxo3-null mice. Genome-wide location analysis combined with gene deletion studies identified the Irf7 gene as a critical target of FOXO3. FOXO3 was identified as a negative regulator of Irf7 transcription. Our data suggest that the FOXO3-IRF7 regulatory circuit represents a novel mechanism for establishing the requisite set points in the interferon pathway.

C57BL/6 mice were obtained from Jackson Laboratories. Foxo3-/- mice in the FVB background were obtained from MMRRC and were backcrossed to C57BL/6 mice at least 5 times to generate congenic mice. C57BL/6 Foxo3+/- heterozygotes were intercrossed to generate Foxo3-/- mice. Mice were maintained at the animal facility of the Institute for Systems Biology and used at 8–12 weeks of age. All animals were housed and handled according to the approved protocols of University of Washington and Institute for Systems Biology's Institutional Animal Care and Use Committees.

Project description:The RIG-I like receptor pathway is stimulated during RNA virus infection by interaction between cytosolic RIG-I and viral RNA structures that contain short hairpin dsRNA and 5M-bM-^@M-^Y triphosphate (5M-bM-^@M-^Yppp) terminal structure. In the present study, an RNA agonist of RIG-I was synthesized in vitro and shown to stimulate RIG-I-dependent antiviral responses at concentrations in the picomolar range. In human lung epithelial A549 cells, 5M-bM-^@M-^YpppRNA specifically stimulated multiple parameters of the innate antiviral response, including IRF3, IRF7 and STAT1 activation, andinduction of inflammatory and interferon stimulated genes - hallmarks of a fully functional antiviral response. Evaluation of the magnitude and duration of gene expression by transcriptional profiling identified a robust, sustained and diversified antiviral and inflammatory response characterized by enhanced pathogen recognition and interferon (IFN)signaling. Bioinformatics analysis further identified a transcriptional signature uniquely induced by 5M-bM-^@M-^YpppRNA, and not by IFNM-NM-1-2bthat included a constellation of IRF7 and NF-kB target genes capable of mobilizing multiple arms of the innate and adaptive immune response. Treatment of primary PBMCs or lung epithelial A549 cells with 5M-bM-^@M-^YpppRNA provided significant protection against a spectrum of RNA and DNA viruses. In C57Bl/6 mice, intravenous administration of 5M-bM-^@M-^YpppRNA protected animals from a lethal challenge with H1N1 Influenza, reduced virus titers in mouse lungs and protected animals from virus-induced pneumonia. Strikingly, the RIG-I-specific transcriptional response afforded partial protection from influenza challenge, even in the absence of type I interferon signaling. This systems approach providestranscriptional, biochemical, and in vivo analysis of the antiviral efficacy of 5M-bM-^@M-^YpppRNA and highlights the therapeutic potential associated with the use of RIG-I agonists as broad spectrum antiviral agents. Kinetic analysis of A549 cells treated with 5'pppRNA and analyzed at 1h, 2h, 4h, 6h, 8h, 12h, 24h or 48h.

A549 cells were either non-treated, treated with RNAiMax only, transfected with 5'pppRNA, or treated with IFNa-2b and analysed at 6h or 24h.
