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。
