Although synthetic nucleic acids have been used for that purpose, they have shown limitations for in vivo and clinical applications. To address this issue, we tested a naturally occurring dsRNA extracted from rice bran (rb-dsRNA) and characterized it as a potent ligand of TLR3 and MDA5. In this study, intranasal administration of rb-dsRNA induced production of type I IFNs by alveolar macrophages and protected mice from morbidity and mortality resulting from respiratory virus infection, such as influenza A virus. This protection was completely absent in mice lacking both TRIF and MDA5, indicating the essential role of TLR3- and MDA5-dependent pathways. Interestingly, IFNAR1-deficient mice retained residual antiviral protection, which was abolished by pharmacological inhibition of caspase 1, but not IL-1β signaling. In fact, rb-dsRNA activated caspase 1 via TRIF, resulting in the release of IL-1β and LDH. In addition to the direct antiviral activity, rb-dsRNA modulated the immune cell population in the lungs by repopulating virus-depleted alveolar macrophages. Our data demonstrate that rb-dsRNA orchestrates IFN-dependent and -independent direct antiviral protection and that it is a potent immune stimulator modulating antiviral immunity in the lungs. These findings open doors to a range of precise immune-modulating studies and therapeutic options."xsd:string |
