タイトル Oral administration of genetically modified Bifidobacterium displaying HCV-NS3 multi-epitope fusion protein could induce an HCV-NS3-specific systemic immune response in mice.

Abstract More than 170 million people worldwide are chronic HCV (Hepatitis C virus) carriers, and about 30% of them will develop progressive liver disease, such as cirrhosis and hepatocellular carcinoma. A combination of pegylated interferon-α with ribavirin, the standard treatment for HCV infection, has been effective in fewer than 50% of patients infected with HCV genotype 1. A strong T cell response against the nonstructural protein 3 (NS3) is important for recovery from acute HCV infection, and an early multi-specific CD4+ helper and CD8+ cytotoxic T cell response is critical for HCV clearance. In the present study, we successfully constructed a genetically modified Bifidobacterium longum (B. longum) displaying recombinant HCV-NS3 peptides containing some CD4 and CD8 epitopes located in the HCV-NS3 region as an oral vaccine against chronic HCV infection. The oral administration of this vaccine could induce NS3-specific immune responses in mice through intestinal mucosal immunity. Our findings suggest that this novel oral vaccine has great potential as a novel oral vaccine against chronic HCV infection.
