| Outline of Final Research Achievements |
Combining the techniques of Virology, Structural biology and Computer science, in this study, a novel approach for antibody design was attempted based on a viral antigen structure using computers.
Designed antibodies were successfully produced in one third of the total. Further, some produced antibodies could exhibit the binding ability to the target viral antigen. Although the improvement of the design system is still required, this method might have a potential to be a next generation approach for the antibody production.

| Academic Significance and Societal Importance of the Research Achievements |
抗体は細胞/分子の単離・標識など生命現象を解明するための研究ツールや、疾患の診断・治療薬として非常に有用だが、標的分子に対して目的の機能・特異性を持つ抗体を取得することは容易ではない。従って、抗体作製のための新たな選択肢（技術）が求められている。そこで、本研究では新規抗体作製法として、抗原の立体構造情報に基づいて、抗原の望む部位へ自由自在に抗体をコンピュータ上で理論的に人工設計するシステム構築に挑戦した。
