• Peptide aptamers are molecules which can specifically bind to a given target protein and have the potential to selectively block the function of the target protein. It has been reported that a peptide aptamer (C1-1) identified from a randomized expression library specifically bound to the core protein of hepatitis B virus and inhibited viral capsid formation and DNA replication in vitro. Adenoviral systems are popular platforms for reliable gene delivery and high-level transient expression in any mammalian cell type in vitro, and have a natural tropism for the liver after systemic administration. In the present study, we explored the feasibility of gene therapy against HBV infection with adenoviral system, and found that systematic administration of recombinant adenovirus encoding the peptide aptamer (C1-1) significantly inhibited viral capsid formation, HBV DNA replication and virion production in vivo. These results suggest an efficient antiviral treatment against HBV infection by delivery of anti-HBV peptide aptamer with recombinant adenovirus.
