    摘要: Cell-free translation and assembly systems allow for HBV capsid assembly under cell-free conditions that also mimic the physiological salt and protein concentrations. These hepatitis virus capsid assembly systems utilize the C-terminal domain (CTD) and N-terminal domain (NTD) of the hepatitis capsid protein in capsid assembly. Uses of the system include the identification of potential new therapeutic strategies and screening of potential therapeutic agents which target these domains and modulate capsid assembly and/or disassembly and other functions of these domains in HBV replication and pathogenesis.

    摘要: The invention provides a protein comprising hepatitis B core antigen (HBcAg) with a sequence of the formula X p Z q X r in an e1 loop, wherein X is a negatively charged amino acid residue, Z is a positively charged amino acid residue, and p, q and r are each independently an integer from 1 to 12, and wherein a sugar is attached to a Z residue. The protein may comprise a first and a second copy of HBcAg in tandem, wherein one or both copies of HBcAg has a sugar attached to the e1 loop. The first copy may have a sugar attached to the e1 loop and the second copy may comprise a peptide epitope in the e1 loop. The protein may be used to induce an immune response against the sugar and hence act as a vaccine.
