Outline of Final Research Achievements

Antigen delivery to antigen presenting cells (APC) is important for development of cancer vaccine. We have found that second dose PEGylated liposomes were selectively taken up by splenic marginal zone B cell (MZ-B), when they were injected with certain interval. This suggests that if antigen is encapsulated into second dose PEGylated liposome, antigen could be delivered to MZ-B, resulting in enhanced anti-tumor immune responses. In this study, we confirmed that delivery of antigen encapsulated in second dose PEGylated liposomes to MZ-B can enhance antitumor immune responses against primary tumor or transplanted tumor.
