Abstract:
MicroRNAs (miRNAs), which can be expressed in a cell-type and tissue-specific manner, can influence the activities of genes that control cell growth and differentiation. Viruses often have clear tissue tropisms, raising the possibility that cellular miRNAs might modulate their pathogenesis. In this Review, we discuss recent findings that some vertebrate viruses either encode miRNAs or subvert cellular miRNAs, and that these miRNAs participate in both the infectious and the latent phase of the viral life cycle.

This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
