Outline of Final Research Achievements

The patients with Non-alcoholic steatohepatitis (NASH) increase in recent years. NASH progresses to be cirrhosis and hepatocellular carcinoma at a high rate. Because there is no effective treatment yet, development of therapy for NASH is desired. We tried to apply immunotherapy to the treatment of NSAH. We focused on fat-targeted iNKT cells and tried to make model mice to confirm the distribution of iNKT cells in NASH-liver. Model mice were used in high-week-aged mice and mice in which glucose metabolism abnormalities were induced by suppressing the secretion of insulin by the administration of streptozotocin (STZ). Degenerative lives were obtained in STZ and high-fat diet treatment mice. iNKT cells in the liver on NASH were decreased compared with that in non-treatment mice.

Academic Significance and Societal Importance of the Research Achievements

NASHは進行すると肝硬変、肝細胞がんを発症する増加傾向にある疾患で、効的な治療法が未だ開発されていない。治療法の開発に必要なモデル動物の作成を試みた。マウスの作成には高脂肪飼料を給餌したのみの群ではNASH用の組織像は認められなかったインスリンの分泌を抑制することで糖代謝異常を誘導させたマウスに、高脂肪食を給餌すると脂肪による肝臓組織の変性が認められた。血清生化学測定でも肝臓の機能障害が認められた。この組織中のiNKT細胞の存在は未処置群に対して減少した。この結果からiNKT細胞を導入することでNASHによる病変の改善が予想される。現在、自己細胞からiNKT細胞の誘導法を検討している。
