چکیده انگلیسی
Autographa californica multiple nucleopolyhedrovirus (AcMNPV) can easily enter and transduce foreign genes into mammalian cells, but these functions are difficult for Bombyx mori nucleopolyhedrovirus (BmNPV). In this study, we investigated the induction of antibody production in mice immunized with an engineered BmNPV. The GP64 of BmNPV (BmGP64) was replaced with the GP64 of AcMNPV (AcGP64); this construct, designated BmNPVÎbgp/AcGP64, displays AcGP64 on the surface of BmNPV. The Neospora caninum antigen (NcSRS2) expression cassette, consisting of the cytomegalovirus immediate-early promoter and NcSRS2 from N. caninum, was inserted into BmNPVÎbgp/AcGP64; this construct was designated BmNPVÎbgp/AcGP64/SRS2. For comparison, AcMNPV/SRS2, which contains the same NcSRS2 expression cassette as for BmNPVÎbgp/AcGP64, was also constructed. NcSRS2 was expressed in HEK293T cells when the engineered BmNPVs were transduced at a multiplicity of infection of 150. BmNPVÎbgp/AcGP64/SRS2 induced the production of NcSRS2-specific antibodies in mice, whereas AcMNPV/SRS2 and the control BmNPV did not. These results suggest that BmNPV prepared from silkworm hemolymph induces the production of antigen-specific antibodies in immunized mice and can be used for antibody production and vaccine development.
