The innate immune system detects viral infection by recognizing various viral components and triggers antiviral responses (1,2).
Like the toll-like receptor 3 (TLR3), the melanoma differentiation-associated protein 5 (MDA5) recognizes double-stranded (ds) RNA, a molecular pattern associated with viral infection.
MDA5, a member of the DEAD/DEAH-box RNA helicase family (3), consists of an amino-terminal caspase recruitment domain (CARD) and a carboxyl-terminal RNA helicase domain similar to that of the related protein RIG-1.
When stimulated by dsRNA, MDA5 recruits the adaptor protein VISA and ultimately causes the activation of IRF-3 and NF-κB (4).
MDA5 and RIG-1 recognize different types of dsRNA, with MDA5 recognizing poly (I:C).
MDA5-null mice were highly susceptible to infection with picornaviruses, which possess such sequences, demonstrating the importance of MDA5 in innate immunity (5).
