Reverse genetics systems as tools for the development of novel therapies against filoviruses

Year: 2014

Type: review

Abstract: Filoviruses cause severe hemorrhagic fevers with case fatality rates of up to 90%, for which no antivirals are currently available. Their categorization as biosafety level 4 agents restricts work with infectious viruses to a few maximum containment laboratories worldwide, which constitutes a significant obstacle for the development of countermeasures. Reverse genetics facilitates the generation of recombinant filoviruses, including reporter-expressing viruses, which have been increasingly used for drug screening and development in recent years. Further, reverse-genetics based lifecycle modeling systems allow modeling of the filovirus lifecycle without the need for a maximum containment laboratory and have recently been optimized for use in high-throughput assays. The availability of these reverse genetics-based tools will significantly improve our ability to find novel antivirals against filoviruses.
