  • Publication number: 20130195905
    Abstract: A composition for preventing or treating cervical cancer comprising a human papillomavirus plasmodium and an immunity enhancer is provided. A fusion protein including a fusion polypeptide recombined to transform a 3D structure of E6 and E7, which are antigens against types 16 and 18 human papillomavirus (HPV), a signal peptide for secreting the fusion polypeptide outside the cells and an immunity enhancer peptide present in an individual is also provided. The fusion protein may be useful in treating HPV-triggered tumors by inducing an immune response specific to the antigens against the HPV types 16 and 18.

  • Patent number: 7910564
    Abstract: The present invention relates to the IL-12p40 subunit mutant gene which can produce IL-12 (interleukin 12) of human and mouse origin with high activity, the expression vector including above mutant gene and the use of them to DNA vaccine adjuvant. Particularly, it relates to IL-12p40 mutant gene which inhibits the secretion of IL-12p40 but normally secretes active IL- 12p70 by making mutation at Asn-222 (human) or Asn- 220 (mouse) amino acid of IL-12p40, which acts as a competitive inhibitor of active form of IL-12, IL-12p70. Therefore, the IL-12p40 mutant gene of the present invention can be useful for DNA vaccination and gene therapy against various diseases, for example, AIDS, hepatitis C or hepatitis B, cancer, influenza, tuberculosis and malaria, which essentially require cellular immune responses for their therapy.
