VACCINE PREPARATION FOR CANCER TREATMENT

摘要

[Problem] To provide a method of clearly deriving killer T cells and helper T cells in a cancer treatment vaccine in which the vaccine antibody is a synthetic long peptide which is derived from a tumor-specific antigen protein and/or pathogen-derived protein and which simultaneously contains a CD8-positive, cytotoxic T-cell recognizing epitope and a CD4-poritive, helper T-cell recognizing epitope peptide. [Solution] BY simultaneously dosing an immunopotentiating agent with a conjugate of a hydrophobized polysaccharide (the antigen delivery system) to the synthetic long peptide, it is possible to achieve clear derivation of antigen-specific killer T-cells and helper T-cells from the cancer treatment vaccine in which the synthetic long peptide is the antigen.
