Know Thyself: RIG-I-Like Receptor Sensing of DNA Virus Infection.

The RIG-I-like receptors (RLRs) are double-stranded RNA-binding proteins that play a role in initiating and modulating cell intrinsic immunity through the recognition of RNA features typically absent from the host transcriptome. While they are initially characterized in the context of RNA virus infection, evidence has now accumulated establishing the role of RLRs in DNA virus infection. Here, we review recent advances in the RLR-mediated restriction of DNA virus infection with an emphasis on the RLR ligands sensed. [ABSTRACT FROM AUTHOR]
