Outline of Final Research Achievements

This study revealed that the experimental rodents with sensitivity to human pathogens "cotton rats" coexisted with multiple phenotypes, and investigated the phenotypes. As a result, cotton rats coexisted with multiple phenotypes such as metabolic syndrome and chronic kidney disease, which are increasing in morbidity in humans, and can mimic human comorbidities. Furthermore, these phenotypes showed sex-differences, and were associated with autoimmune diseases. As mentioned above, this study showed that cotton rats might be a model of human comorbidity and concluded that they contribute to the elucidation of the interaction between individual diseases.

Academic Significance and Societal Importance of the Research Achievements

高齢化社会は「複数疾患を併発する(併存症)」患者を増加させ、併存疾患の相互作用によりそれらの治療方法が複雑化する。ヒトの併存症を再現する実験動物は、その原因究明や治療法開発に極めて有用である。本研究ではコットンラットの表現型を多数発見し、それらの詳細及び相互作用を明らかにした。例えば、コットンラットの慢性腎臓病には子宮蓄膿症や免疫異常、性ホルモンが密接に関連した。加えてそれらの中にはヒトで問題となる慢性疾患が含まれたことから、コットンラットがヒトの疾患モデルとして有用である可能性が高まった。
