Human cytomegalovirus expresses novel microRNAs during productive viral infection

Abstract excerpt

MicroRNAs (miRNAs) are a large class of approximately 22-nucleotide non-coding RNAs that facilitate mRNA cleavage and translation repression through the RNA interference pathway. Until recently, miRNAs have been exclusively found in eukaryotic organisms. A non-immunogenic molecule requiring minimal genomic investment, these RNAs may offer an efficient means for viruses to modulate both their own and the host's...
