Protective immune responses in ducklings induced by a suicidal DNA vaccine of the VP1 gene of duck hepatitis virus type 1
چکیده انگلیسی

A suicidal DNA vaccine based on a Semliki Forest virus (SFV) replicon was evaluated for the development of a vaccine against duck hepatitis virus type 1 (DHV-1). The VP1 gene of DHV-1 was cloned and inserted into pSCA1, an SFV DNA-based replicon vector. The resultant plasmid, pSCA/VP1, was transfected into BHK-21 cells and the antigenicity of the expressed protein was confirmed using an indirect immunofluorescence and western blot assay. Immunogenicity was studied in ducklings. Ducklings were injected intramuscularly two times with pSCA/VP1 at 14 days intervals. Anti-DHV-1 antibodies were detected by ELISA, the lymphocyte proliferation response was also tested by the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide method and neutralizing antibodies were measured by microneutralization tests. Our results showed that DHV-1-specific antibodies, neutralizing antibodies and lymphocyte proliferation were well induced in ducklings. Furthermore, all the ducklings were protected against challenge with wild DHV-1. In conclusion, we demonstrate that the suicidal DNA vaccine is a promising vaccine candidate facilitating the prevention of duck hepatitis caused by DHV-1.
