Abstract

The RNA interference mechanism utilizes short RNA duplexes to either suppress or induce target gene expression. Post-transcriptional regulation mediated by microRNA is an integral component of innate antiviral defense. The magnitude and the efficiency of viral restriction guided by RNA-based defenses, as well as the full physiological implication of host-pathogen engagement, constitute exciting areas of investigation in the biology of non-coding RNAs.
