Outline of Final Research Achievements

Idiopathic pulmonary fibrosis is a poor prognosis disease with irreversible lung fibrosis and an unpredictable and diverse clinical course, and the development of new treatments is urgently needed. The lipid mediators sphingosine 1-phosphate (S1P) and lysophosphatidic acid (LPA) have been shown to have important functions in lung fibrosis. In this study, we found that the expression of lipid phosphate phosphatase 3 (LPP3), which has degrading activity of S1P and LPA, was decreased in alveolar epithelial cells of fibrotic lung. These findings suggest that LPP3 may be an important suppressor of lung fibrosis and that LPP3 may be a new therapeutic target for pulmonary fibrosis.

Academic Significance and Societal Importance of the Research Achievements

スフィンゴシン1-リン酸(S1P)とリゾホスファチジン酸(LPA)は肺線維症以外に急性肺損傷に関与していること,最近,新型コロナウイルス感染症でLPA産生酵素の発現が亢進していることが報告されていることから,本研究成果は肺線維症も含めた肺疾患におけるS1PとLPAの分解活性を持つ脂質リン酸ホスファターゼ3(LPP3)の病態生理学的意義の解明および新規治療法の基盤開発にも繋がる可能性がある。また,LPAやS1Pががんや動脈硬化などの病態に関与することが示されていることから,本研究成果が他の疾患の治療法開発にも波及することが期待される。
