A targeting delivery system loaded with whole-cell components, which relates to the technical field of immunotherapy. The targeting delivery system is a nano-sized or micron-sized particle with a target head on the surface, and the particle is loaded with whole-cell components of cancer cells or cancer tissues; the whole-cell components are water-soluble ingredients and water-insoluble ingredients of whole cells in cells or tissues, and the water-insoluble ingredients are dissolved by a solubilizer; and the target head binds to a molecule on the surface of a specific cell or tissue, so as to help the particle to enter the cell or tissue. According to the targeting delivery system, a specific solubilizer is used to solubilize the water-insoluble part, which allows same to be dissolved in an aqueous solution, so that the whole-cell antigens of the water-soluble ingredients and the water-insoluble ingredients in cancer cells or tissues can be combined to prepare a cancer vaccine. In addition, the target head capable of targeting antigen-presenting cells is added to improve the phagocytosis efficiency of the antigen-presenting cells in an active targeting manner, thereby improving the effect of preventing or treating cancer. |
