A Versatile RNA Vector for Delivery of Coding and Noncoding RNAs

Abstract

The discovery that RNA viruses, lacking any DNA intermediate, can be engineered to express both coding and noncoding RNAs suggests that this platform may have therapeutic value as a delivery vehicle. Here we illustrate that a self-replicating, noninfectious RNA, modeled on influenza virus, provides one such example of a versatile in vivo delivery system for silencing and/or expressing a desired RNA for therapeutic purposes.
