Drosophila miR-956 suppression modulates Ectoderm-expressed 4 and inhibits viral replication.

Small non-coding microRNAs (miRNAs) can modulate the outcome of virus infection. Here we explore the role of miRNAs in insect-virus interactions, in vivo, using the natural Drosophila melanogaster-Drosophila C virus (DCV) model system. Comparison of the miRNA expression profiles in DCV-infected and uninfected flies showed altered miRNA levels due to DCV infection, with the largest change in abundance observed for miR-956-3p.
