Outline of Final Research Achievements

In this study, we examined the induction effects of hybrid liposomes (HL-MUC-1/mB7-1) composed of phospholipids (DMPC) and nonionic surfactants (Tween 80) including synthetic mucin MUC-1 antigen peptides and recombinant mB7-1 membrane proteins on the cancer immunotherapy in vitro and in vivo. CD8+ T cells from the mice intravenously administrated HL-MUC-1/mB7-1 had a tendency to increase the cytotoxicity to the breast cancer cells in vitro, and the prolonged survival was observed in mice implanted with breast cancer cells after the administration of HL-MUC1/mB7-1, suggesting the possibility of novel cancer vaccine using hybrid liposomes.
