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.
