    Analysis of MDA5 or RIG-I knockout mice demonstrates that this pathway is central for innate immunity against viral infection [17]. RIG-I is a cytosolic sensor of viral RNA that plays crucial roles in the induction of type I IFNs [24–27]. Next-generation RNA sequencing shows that RIG-I preferentially associates with shorter 5′ppp containing viral RNA molecules in infected cells as well as subgenomic defective interfering particles [11].

    These results suggest that the helicase domain suppresses downstream signaling through the CARD domains in non-viral condition [5]. Considering the binding ability of the helicase domain to poly(I:C), RIG-I is an essential component of the signaling pathway upstream of IRF-3 and NF-κB, and probably the direct sensor of viral double-stranded RNA [5,23]. Interestingly, it has been demonstrated that RIG-I is expressed by the induction of inflammatory cytokines in various types of human cells, including endothelial cells, vascular smooth muscle cells, urinary bladder epithelial cells, gingival fibroblasts, and bronchial epithelial cells [9,17–22].
