Immunization of mice against West Nile virus with recombinant envelope protein.
نویسندگان
چکیده
West Nile (WN) virus is a mosquito-borne flavivirus that emerged in the United States in 1999 and can cause fatal encephalitis. Envelope (E) protein cDNA from a WN virus isolate recovered from Culex pipiens in Connecticut was expressed in Escherichia coli. The recombinant E protein was purified and used as Ag in immunoblot assays and immunization experiments. Patients with WN virus infection had Abs that recognized the recombinant E protein. C3H/HeN mice immunized with E protein developed E protein Abs and were protected from infection with WN virus. Passive administration of E protein antisera was also sufficient to afford immunity. E protein is a candidate vaccine to prevent WN virus infection.

Protective and therapeutic capacity of human single-chain Fv-Fc fusion proteins against West Nile virus.
West Nile virus has spread rapidly across the United States, and there is currently no approved human vaccine or therapy to prevent or treat disease. Passive immunization with antibodies against the envelope protein represents a promising means to provide short-term prophylaxis and treatment for West Nile virus infection. In this study, we identified a panel of 11 unique human single-chain vari...

The last sentence of the ‘‘WNV DNA Vaccine, Control Plasmid and E-protein’’ section of the Materials and Methods should read: ‘‘For protein booster vaccine formulation the E-protein was adjuvanted with 10 mg Matrix-M1 adjuvant (Novavax AB, Uppsala, Sweden).’’ In addition, the following sentence should be inserted as the last sentence of the ‘‘Vaccination Procedures’’ section of the Materials an...
متن کاملEffect of IL-2 co-expressed or co-inoculated with immuno-dominant epitopes from VP1 protein of FMD virus on immune responses in BALB/c mice
Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...
