Outline of Final Research Achievements

Antigenic shift is well known as an emerging mechanism of influenza virus. Previous study showed that the antigenic shift sometimes affects as a negative factor for the viral replication. Therefore, we focused on the PA and PB2 subunits, which are essential subunits for the viral replication. Consequently, the viral replication was significantly impaired by introducing either PA or PB2 subunit as inhibitor. By fragmentation of the subunit, the inhibitory effect was emphasized. In addition we constructed the mass expression system and purification method for the fragments. Future applications are expected.
