Outline of Final Research Achievements

Phosphorylated (p-) TDP-43 inclusions were frequently observed in the axons of the lower motoneurons of 19 autopsy cases with amyotrophic lateral sclerosis (ALS). The forms of the inclusions were granuloreticular and massive aggregate types. Presynaptic p-TDP-43 inclusions were observed around the neurons of the red nucleus, however, postsynaptic p-TDP-43 aggregates were not seen. The finding showed transsynaptic p-TDP-43 propagation was not examined in the ALS patients. Stages of brain lesions by phosphorylated tau-immunohistochemistry in the Guam PDC, Guam ALS and Guam controls were identified five (0 - IV). Differences from those of Alzheimer’s disease were massive progression into brainstem and rare neuropile threads.

Academic Significance and Societal Importance of the Research Achievements

アルツハイマー病(AD),筋萎縮性側索硬化症(ALS),前頭側頭葉変性症,パーキンソン病などのレビー小体病,グアム島のパーキンソン認知症(G-PDC)などは原因不明で根本的治療法が無い致死性の疾患である。これらの疾患は特異的蛋白が脳脊髄に発現して伝播拡散し沈着することで発症する。これらの変性疾患を予防および治療するには、それぞれの特異蛋白がどのようにして神経組織に発現し拡散伝播するのか、そのメカニズムを解明することが重要である。本研究はALSの脳脊髄におけるリン酸化TDP-43の軸索内所見を初めて明らかにし、G-PDCのリン酸化タウの進展様式がADとは異なることを見出し報告した。
