Immune responses are both pathogen and cell type-specific. The innate arm of immunity is characterized by rapid intracellular signaling cascades resulting in the production of hundreds of antimicrobial effectors that protect the host organism. Long noncoding RNAs have been shown to operate as potent modulators of both RNA and protein function throughout cell biology. Emerging data suggest that this is also true within innate immunity. LncRNAs have been shown to regulate both innate immune cell identity and the transcription of gene expression programs critical for innate immune responses. Here, we review the diverse roles of lncRNAs within innate defense with a specific emphasis on host-virus interactions.
Keywords: Innate immunity; gene regulation; host-virus interactions; long noncoding RNAs.
