[Generation of recombinant vaccinia virus expressing attachment glycoprotein of Nipah virus].

| Abstract |
The mammalian condon optimized G gene was synthesized by over-lapping PCR and used to generate recombinant vaccinia virus, rWR-NiV-G. The expression of Nipah virus G protein in rWR-NiV-G infected HeLa cells was confirmed by western-blot with NiV G protein specific mouse antiserum generated by DNA immunization.The recombinant G protein showed sensitive and specific antigenic reaction to rabbit serum anti-Nipah virus in indirect florescence. Syncytium formation was induced in BHK cells by rWR-NiV-G infection following NiV F protein expressing plasmid pCAGG-NiV-F transfection. Immunization with rWR-NiV-G elicited G protein specific antibody responses in mice. The prokaryotic expressing G protein fragment showed sensitive and specific antigenic reaction to NiV G protein specific antibody from rWR-NiV-G immunized mice serum in indirect ELISA. Furthermore, the G protein specific antibodies could neutralize the infectivity of the recombinant Vesicular Stomatitis Virus pseudotype VSVAG * F/G, in which the VSV envelope protein G gene was replaced with the green fluorescent protein gene (VSVAG * G, Whitt MA) and complemented with Nipah virus F and G glycoprotein expressed in transient (VSVAG * F/G).The results here demonstrated the G protein expressed by rWR-NiV-G keeps native immunogenicity and biological activity. The recombinant virus could be promising vaccine strategy for the prevention of Nipah virus.
