Outline of Final Research Achievements

Therapeutic antibodies utilizes the specificity of one monoclonal antibody to recognize one antigen. The aim of the study is to establish a method to establish monoclonal antibodies that can treat all influenza A virus infections. To that end, several methods of immunizing mice, several fusion methods, and some screening methods to detect antibody-producing hybridomas were performed, and finally, monoclonal antibodies which recognize multiple HA subtypes were established. That is, we have found a suitable method for producing antibodies that recognize multiple HA subtypes of influenza A virus. This method can also be applied to establish antibodies for the treatment of other viral infections.

Academic Significance and Societal Importance of the Research Achievements

抗体医薬品は、一つの抗体が一つの抗原を認識する特異性を利用した、副作用の少ない効果的な治療法として、がん、免疫炎症性疾患、感染症、その他の分野で利用されている。しかしインフルエンザの治療法としては未だ実用化されていない。インフルエンザウイルスの主要抗原HA蛋白質の抗原性がH1からH18までのHA亜型により、大きく異なることが大きな障害となっている。そこで本研究では、全てのHA亜型を認識する抗体の作出に適した方法を探索した。
