The application belongs to the field of
immunotherapy and discloses a conveying
system for conveying water-soluble components and non-water-soluble components of whole-
cell components by using nano-scale or micron-scale particles and application of the conveying
system in preparation of vaccines for preventing and treating cancers. The whole-
cell component conveying
system is composed of the nano-scale or micron-scale particles and the whole-
cell components loaded by the particles, wherein the whole-cell components are water-soluble components and non-water-soluble components of whole cells in cells or tissues. The water-soluble components and the non-water-soluble components are loaded in the nano particles or the micron particles, so that variant proteins or polypeptides generated by the cancers in the cell components are loaded in the nano particles or the micron particles. Substances with
immunogenicity, which are generated due to
disease mutation, in the whole-cell components can be used for preventing and treating the cancers. The whole-cell component conveying system can be used for preparing the vaccines for preventing and / or treating the cancers.
