Outline of Final Research Achievements

Although mammalian target of rapamycin inhibitors (mTORi) are used to treat various malignancies, they frequently induce active alveolitis and dyslipidemia. Abnormal lipid metabolism affects alveolar surfactant function and results in pulmonary disorders; however, the pathophysiology of lung injury and its relationship with lipid metabolism remain unknown. We investigated the relationship between lipid metabolism and alveolar epithelial injury, focusing on peroxisome proliferator-activated receptor-γ (PPAR-γ) as a lipid stress-related factor in mTORi-induced lung injury.
In conclusion, the pathogenesis of mTORi-induced lung disease may be involved in alveolar epithelial injury, via lipid metabolic stress associated with downregulated PPAR-γ expression. Focusing on the relationship between lipid metabolic stress and alveolar epithelial injury represents a potentially novel approach to the study of pulmonary damage.

Academic Significance and Societal Importance of the Research Achievements

mTOR阻害薬(mTOR-i)は抗腫瘍作用を有する薬剤ではあるが、 薬剤性肺障害を高頻度(約30%)に発症すると報告されている。本研究においては、mTOR-iによる薬剤性肺障害の病態解明を目的とし、同薬剤による脂質代謝への影響と肺胞上皮への作用について、特に脂質関連因子(PPAR-γ)に着目して検討を行った。
mTORi肺障害の病態は局所性ないし全身性の脂質代謝ストレスを介した肺胞上皮傷害であり、PPAR-γの発現低下が肺内脂質の恒常性の破綻と炎症を惹起することで、上皮傷害に関与したと考えられた。脂質代謝ストレスと肺胞上皮傷害の関係性は、今後の肺障害研究において新たな糸口になると考えられた。
