Outline of Final Research Achievements

The species difference of major histocompatibility complex (MHC) genes
limits the usage of model animals including mouse for evaluation of biopharmaceuticals such as vaccines. However, humanization of more than 20 MHC family genes scattered in 4,000,000 bp MHC region is almost impossible by the conventional techniques. In this study, we generated MHC humanized cells via genome editing technology and chromosome engineering technology.

Academic Significance and Societal Importance of the Research Achievements

新興感染症やガンなどに対するワクチンの開発では前臨床試験の段階でヒト免疫環境下における薬効を示すことが要求される場合もあり、現在の技術では迅速に開発を進めることは容易ではない。主要組織適合遺伝子複合体(MHC)ヒト化動物ができれば、ワクチンなどの医薬品開発の促進に大きく貢献できると期待される。またガン抗原に応答するヒトT細胞受容体の分離・同定に応用すれば、抗腫瘍免疫療法の開発などにも極めて有用なツールになると期待される。
