Abstract: Retinoic acid-inducible geneⅠ(RIG-Ⅰ) is a key innate immune pattern-recognition receptor that triggers type Ⅰ interferon, cytokine and chemotactic factor expression upon detection of intracellular double-strand RNA of viral origin. It plays an important role in the constructing of antiviral innate immunity. Researches on the mammal show that RIG-Ⅰ takes part in the inhibition of AIV, NDV,and so on. RIG-Ⅰ is absent in chickens and duck RIG-Ⅰ can initiate an antiviral IFN response in chicken cell line. This review provided an overview of mechanism of RIG-Ⅰ activation with an expanded discussion on the potentials of improving avian antiviral ability and enhancing basis researches of avian innate immunity.

Key words: retinoic acid-inducible geneⅠ; avian; innate immunity; antivirus
