MANEA and viral infectious disease: However, recent studies have indicated that BmCPV RNAs can be cut by Dicer-2 and an uncharacterized endo-RNase to produce thousands of small viral RNAs (vsRNAs) as a strategy for opposing virus infection [22], and transcripts of BmCPV can also be processed to viral microRNAs (vmiRNAs) to promote virus infection [23,24,25,26].
