Zusammenfassung: | The invention relates to an antigen and adjuvant co-delivery nanometer vaccine applied to liver cancer immunization therapy. Sodium alginate and polymine are used as carrier materials, liver cancer specific polypeptide antigen phosphatidylinositol proteoglycan 3127-136 peptides(GPC3127-136, AMFKNNYPSL) are used as immunizing antigens, CpG oligodeoxynucleotide is used as an adjuvant, and through static electricity interaction, the antigen and adjuvant co-delivery nanometer vaccine is prepared, wherein the mass ratio of the carrier materials to the immunizing antigens to the adjuvant is 1: (1-10): (0.3-0.8). The nanometer vaccine disclosed by the invention can increase the endocytosis quantity of dendritic cells (dendritic cell, DC) to the antigen and the adjuvant, and through raising costimulatory molecules on the surfaces of the DCs and promoting the secretion of cytokine of TNF-a, IL-6 and the like, arousing organisms to produce effective immune response is facilitated; and besides, the raw materials are che |
