Host factors for replication and transcription of the influenza virus genome

Kyosuke Nagata et al. Rev Med Virol. 2008 Jul-Aug.

Abstract

For replication and transcription of the influenza virus genome of eight-segmented and negative-stranded RNAs, not only viral factors but also host-derived cellular factors (host factors) are required. This paper focuses on the identification and characterisation of the host factors involved in replication and transcription of the influenza virus genome, reviewing recent progresses in the related molecular mechanisms. Functional assay systems for screening of host factors using cell-free reconstitution systems and an yeast-based influenza virus replicon system are highlighted. We have summarised the property of host factors comprehensively and provided a clue for the perspective in the determination mechanism of host range and virulence and the development of a new strategy to control the influenza virus.
