Construction of eukaryotic expression vector with mBD1-mBD3 fusion genes and exploring its activity against influenza A virus..     ///    These observations suggested that the recombinant mBD1-mBD3 might be developed into an agent for influenza prevention and treatment..     ///    The eukaryotic expression vectors pcDNA3.1(+)/mBD1-mBD3 were constructed successfully by overlap-PCR and transfected into Madin-Darby canine kidney (MDCK) cells.     ///    "The MDCK cells transfected by pcDNA3.1(+)/mBD1-mBD3 were obtained by G??? screening, and the mBD1-mBD3 stable expression pattern was confirmed in MDCK cells by RT-PCR and immunofluorescence assay. "    ///    This study demonstrates that mBD1-mBD3 expressed by the recombinant plasmid pcDNA3.1(+)/mBD1-mBD3 could inhibit influenza A virus replication both in vitro and in vivo.     ///    "Furthermore, BALB/C mice were injected with liposome-encapsulated pcDNA3.1(+)/mBD1-mBD3 through muscle and then challenged with the A/PR/8/34 virus.
