Oligonucleotides bearing free, uncapped 5' phosphate group(s) are recognized by RIG-I, leading to the induction of type I IFN, IL-18 and IL-1&bgr; production. Bacterial RNA also induces type I IFN production. 5' phosphate oligonucleotides and bacterial RNA can be used for inducing an anti-viral response or an anti-bacterial response, in particular, type I IFN and/or IL-18 and/or IL-1&bgr; production, in vitro and in vivo and for treating various disorders and diseases such as viral infections, bacterial infections, parasitic infections, tumors, allergies, autoimmune diseases, immunodeficiencies and immunosuppression. Single- stranded 5' triphosphate RNA can be used for inducing an anti-viral response, an anti- bacterial response, or an anti-tumor response, in particular, type I IFN and/or IL-18 and/or IL- 1&bgr; production, in a target cell-specific manner. |
