Outline of Research at the Start

研究リソースの欠如で研究がほとんど行われて来なかった、末梢型Lewy小体を、形態学的研究に加え、蛋白化学、マウスへの伝播実験を含む分子病理学的検討を加えることで、中枢型・脳幹型レビー小体を含めた、Lewy小体病全体における生物学的意義を追求する。対象は、高齢者ブレインバンク登録例で、中枢・末梢の網羅的スクリーニングにより、Lewy小体病理の出現と伝播形式を、中枢、脳幹に末梢を加え検討する。さらに末梢型レビー小体について、免疫組織科学的、超微形態的検討を加える。さらに高度蓄積例に、Western blot、マウスへの伝播実験における、比較検討を加える。

Outline of Final Research Achievements

Pure autonomic failure is a type 1 Lewy body disease, with the peripheral autonomic nervous system being the primary site of lesions. For diagnosis, it is necessary to exclude peripheral neuropathy, mainly multiple system atrophy and amyloidosis. MRI is useful for the former, and nerve conduction velocity tests and sural nerve biopsy are useful for the latter. Lewy body pathology was frequently found in skin biopsies performed based on positive MIBG myocardial scintigraphy and sweating disorder. In cases with a long history of disease, cognitive symptoms are often present without motor disorders, which matches the pathological image of diffuse Lewy body disease proposed by Kosaka. In addition to peripheral elements, it is characterized by a combination of central elements, and because the progression is slow, it is important to consider both, making this a disease area in which the involvement of neurology is important.

Academic Significance and Societal Importance of the Research Achievements

純粋自律神経不全症は,剖検例の報告は非常に少ないが,当施設で長期経過を観察し剖検をえられた3例の神経病理学的特徴を検討した.3例とも末梢自律神経系に強調されるLewy関連病理を認め,脊髄,脳幹,大脳までひろがりを認めた.一方,中脳黒質の病理は相対的に軽度にとどまった.これは臨床的に長期間自律神経症状のみを認めていたことと合致した.また,いずれの例も海馬CA2にLewy関連病理を認め,純粋自律神経不全症の晩期には認知機能にも留意が必要であることを支持する所見であった.本検討は全身臓器も含めた検索がLewy小体病の自然経過,進展形式を理解するうえで重要であることを示す.
