Abstract
The antiviral RNA interference (RNAi) pathway processes viral double-stranded RNA (dsRNA) into viral small interfering RNAs (vsiRNA) that guide the recognition and cleavage of complementary viral target RNAs. In RNA virus infections, viral replication intermediates, dsRNA genomes or viral structured RNAs have been implicated as Dicer-2 substrates. In a recent publication, we demonstrated that a double-stranded DNA virus, Invertebrate iridescent virus 6, is a target of the Drosophila RNAi machinery, and we proposed that overlapping converging transcripts base pair to form the dsRNA substrates for vsiRNA biogenesis. Here, we discuss the role of RNAi in antiviral defense to DNA viruses in Drosophila and other invertebrate model systems.Entities:
