| Background | Antiviral innate immunity depends on the combination of parallel pathways triggered by virus detecting proteins in the Toll-like receptor (TLR) family and RNA helicases, such as Rig-I (retinoic acid-inducible gene I) and MDA-5 (melanoma differentiation-associated antigen 5), which promote the transcription of type I interferons (IFN) and antiviral enzymes (1-3). TLRs and helicase proteins contain sites that recognize the molecular patterns of different virus types, including DNA, single-stranded RNA (ssRNA), double-stranded RNA (dsRNA), and glycoproteins. These antiviral proteins are found in different cell compartments; TLRs (i.e. TLR3, TLR7, TLR8, and TLR9) are expressed on endosomal membranes and helicases are localized to the cytoplasm. Rig-I expression is induced by retinoic acid, LPS, IFN, and viral infection (4,5). Both Rig-I and MDA-5 share a DExD/H-box helicase domain that detects viral dsRNA and two amino-terminal caspase recruitment domains (CARD) that are required for triggering downstream signaling (4-7). Rig-I binds both dsRNA and viral ssRNA that contains a 5-triphosphate end not seen in host RNA (8,9). Though structurally related, Rig-I and MDA-5 detect a distinct set of viruses (10,11). The CARD domain of the helicases, which is sufficient to generate signaling and IFN production, is recruited to the CARD domain of the MAVS/VISA/Cardif/IPS-1 mitochondrial protein, which triggers activation of NF-κB, TBK1/IKKε, and IRF-3/IRF-7 (12-15).The DExD/H-box family helicase laboratory of genetics and physiology 2 (LGP2, DHX58) is a Rig-I-like receptor (RLR) that lacks the CARD domain and associated signaling ability (6,16). Research studies demonstrate that LGP2 helicase binds dsRNA and inhibits the Rig-I-like receptors Rig-I and MDA-5. Expression of LGP2 is induced by interferon, dsRNA, and viral infection (17). Studies using LGP2-deficient animals demonstrate a complicated interaction between LGP2 and the other RLRs that involves both positive and negative effects on interferon regulation (18-20). In addition, LGP2 may regulate apoptosis, contribute to CD8+ T cell survival, and protect cancer cells from ionizing radiation (21,22). |
