  • Immune Adjuvant Comprising Hepatitis B Virus-Derived Polypeptide
    Publication number: 20230321222
    Abstract: Provided is an immune adjuvant including a polypeptide consisting of an amino acid sequence of SEQ ID NO: 2. The polypeptide is a hepatitis B virus-derived polypeptide, is effective in enhancing immunity through co-administration with vaccines as a single immune adjuvant, and in particular, when coadministered with another immune adjuvant, may exhibit a more remarkable immunity enhancement effect. Furthermore, the polypeptide is a single molecule having only 6 amino acids, is not cytotoxic, and has excellent in vivo stability.

  • Hepatitis B virus-derived polypeptide and anti-viral use thereof
    Patent number: 11692011
    Abstract: A hepatitis B virus-derived polypeptide exhibits anti-viral effects not only on HIV-1 and HBV but also on all viruses by increasing the expression of type I interferon. The hepatitis B virus-derived polypeptide has a synergistic effect when co-administered with a conventional anti-viral agent. The hepatitis B virus-derived polypeptide is effectively usable in the treatment of virus-related diseases such as AIDS or liver diseases.
