Fig. 2. The mechanism of immune function of vaccine liposomes. After being injected into the body, the liposome vaccine is ingested by macrophages and stored in it to produce ”pool effect”. Then the antigen is presented by APC cells (especially DC) and transferred to the lymph nodes. After extracting the antigen information, CD4+CD8+ was activated by MHC-I and MHC-II respectively to secrete specific antibodies and a series of cytokines. Tumor cells are cleaved and inactivated after binding to CTL.
