摘要
RLRs - the retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) - are novel cytoplasmic RNA helicases that recognize viral RNA present within the cytoplasm [ 1 ]. The identification of the MAVS (mitochondrial antiviral signaling) adaptor protein as a member of the RIG-I-like receptors (RLRs) signaling pathway links the mitochondria to the mammalian antiviral defense system [2].
