| 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.
