Recent advances in understanding viral evasion of type I interferon

The type I interferon (IFN) system mediates a wide variety of antiviral effects and represents an important first barrier to virus infection. Consequently, viruses have developed an impressive diversity of tactics to circumvent IFN responses. Evasion strategies can involve preventing initial virus detection, via the disruption of the Toll-like receptors or the retinoic acid inducible gene I (RIG-I) -like receptors, or by avoiding the initial …
