Assembly of hepatitis delta virus-like empty particles in yeast.

Large delta antigen (L-HDAg) of hepatitis delta virus (HDV) and small-form hepatitis B surface antigen (HBsAg) of helper hepatitis B virus have previously been shown to be the minimum components for the assembly of HDV-like particles in mammalian cells. Extending from this finding, we coexpressed L-HDAg and small HBsAg in Saccharomyces cerevisiae to study their assembly in yeast cells. The asse...

Immunization with hepatitis C virus-like particles protects mice from recombinant hepatitis C virus-vaccinia infection.

We have recently demonstrated that immunization with hepatitis C virus-like particles (HCV-LPs) generated in insect cells can elicit both humoral and cellular immune responses in BALB/c mice. Here, we evaluate the immunogenicity of HCV-LPs in HLA2.1 transgenic (AAD) mice in comparison to DNA immunization. HCV-LP immunization elicited a significantly stronger humoral immune response than DNA imm...

Avian lymphoid leukosis: Virus-like particles in kidney Cells

Generation of hepatitis C virus-like particles by use of a recombinant vesicular stomatitis virus vector.

Hepatitis C virus (HCV), a major etiologic agent of hepatocellular carcinoma, presently infects approximately 400 million people worldwide, making the development of protective measures against HCV infection a key objective. Here we have generated a recombinant vesicular stomatitis virus (VSV), which expresses the HCV structural proteins, by inserting the contiguous Core, E1, and E2 coding regi...

Transient expression of virus-like particles in plants: a promising platform for rapid vaccine production

Transient expression is an efficient and fast system to express recombinant proteins which has been used in different eukaryotic hosts such as mammalian and plant cells. Several applications of this system have so far been used which expression of proteins of interest is one of them. Recently, plants have attracted attention for being used as hosts for the production of recombinant pharmaceutic...
