| Outline of Final Research Achievements |
Adjuvant is an important component for effective vaccination and antitumor therapy. Establishment of local and switchable adjuvant is considered to be an efficient strategy to reduce side effects and efficiently activate innate immune responses. The purpose of this study is the establishment of a novel nucleic acid adjuvant that can trigger the activation of innate immune system in response to X-ray irradiation. In this study, type-C CpG ligands contained with cystamine-modified cytosine were used and showed its structural change by X-ray irradiation, albeit their low efficiency. These results showed these ligands could be a switchable activator and further investigation will be needed to improve their efficiency.
