The invention relates to a preparation method of an
autophagy-imitated immune
cell supported antitumor therapeutic agent. The preparation method comprises steps as follows: an antitumor therapeutic agent,
cell membranes and immune cells are taken as raw materials, immune
cell membranes are extracted to encapsulate the antitumor therapeutic agent, nano-particles containing
apoptosis groups are co-cultured with the immune cells after being formed, the nano-particles are phagocytized by the immune cells, the antitumor therapeutic agent is enabled to be indirectly encapsulated into the immune cells, and the
autophagy-imitated immune cell supported antitumor therapeutic agent is prepared. Compared with the prior art, the antitumor therapeutic agent is encapsulated with the cell membranes containing the
apoptosis groups, the
phagocytosis quantity of the antitumor therapeutic agent by the immune cells is increased, cell carriers meeting various demands are prepared, the problems of irregularrelease and low
phagocytosis quantity of the therapeutic agent due to adoption of a traditional supporting method are solved, and meanwhile,
toxicity of drugs for the cell carriers is reduced.
