| Outline of Research at the Start |
リンパ脈管筋腫症（LAM）は平滑筋細胞様のLAM細胞が増殖、肺に転移し、多発性嚢胞を形成する希少難病である。この難病の克服には病態解明や診断・治療法開発の観点から新たなバイオマーカー（BM）の開発が急務である。本研究では、最先端の技術（細胞外小胞・プロテオミクス技術・バイオインフォマティクス）を駆使し、多様な検体(血液・肺組織・肺胞洗浄液・LAM細胞)から得られたマルチオミックスデータの統合解析という包括的アプローチにより、LAMの病態解明からBMの開発に挑む。

| Outline of Final Research Achievements |
Lymphangioleiomyomatosis (LAM) is a rare and progressive cystic lung disease, which is intrinsically caused by the proliferation of so-called 'LAM cells'. In the current project, we focused on extracellular vesicles derived from patients’ blood and LAM cell lines to identify novel biomarkers for lymphangioleiomyomatosis in a comprehensive approach. Biomarker proteins were further validated in LAM lungs by Immunohistochemistry stains, and at least, four proteins were positively stained, suggesting derivation from the LAM cells in the lung.

| Academic Significance and Societal Importance of the Research Achievements |
LAMは難病ではあるが、希少疾患のため研究助成や研究者が少ないのが現状である。本研究では、LAMの新たな診断バイオマーカーを絞り込むことができた。これらの成果は、LAMの診断に寄与し、将来の治療法開発につながる可能性がある。
