Abstract

Japanese encephalitis virus (JEV) is an important pathogen causing febrile syndrome, encephalitis, and death. Envelop (E) glycoprotein is the major target of inducing neutralizing antibodies and protective immunity in host. In this study, E glycoprotein of JEV was expressed in Spodoptera frugiperd 9 cells as a fusion protein containing a gX signal sequence of pseudorabies virus. This purified HcE recombinant protein was evaluated for their immunogenicity and protective efficacy in guinea pig. The survival rates of guinea pig immunized with HcE protein was significantly increased over that of JE vaccine. This result indicates helpful information for developing a subunit vaccine against JEV.
