    Abstract:
    Baculovirus expression vectors are extensively used for the delivering foreign genes and expression of recombinant proteins in insect and mammalian cells. Modified baculoviruses containing mammalian promoter elements (BacMam viruses) for an efficient transient and stable transduction of diverse mammalian cells prove a high level of heterologous proteins' expression both in vitro and in vivo. Recombinant baculovirus vectors containing mammalian expression cassette with cytomegalovirus promoter, green or red fluorescent protein gene, polyadenylate signal SV40pA, and polylinker MCS were constructed for the delivery of genes encoding hepatitis C virus structural proteins into mammalian cells. In Hek293T and Huh7 cells formation of glycoprotein complexes and HCV-like particles was observed. A high efficiency of the baculovirus-mediated gene transfer and expression of the virus envelope proteins in mammalian cells was demonstrated with using fluorescence, flow cytometry and immunoblot techniques.
