We established a plasmid-based system for generating infectious
influenza virus-like particles entirely from cloned cDNAs. Human
embryonic kidney cells (293T) were transfected with plasmids encoding
the influenza A virus structural proteins and with a plasmid encoding
an influenza virus-like viral RNA (vRNA) which contained an antisense
copy of the cDNA for green fluorescence protein (GFP) flanked by an RNA
polymerase I promoter and terminator. Intracellular transcription of
the latter construct by RNA polymerase I generated GFP vRNA that was
packaged into influenza virus-like particles. This system, which
produced more than 104 infectious particles per ml of
supernatant, would be useful in studies of influenza virus replication
and particle formation. It might also benefit efforts in vaccine
production and in the development of improved gene therapy vectors.
