Outline of Research at the Start

慢性外傷性脳症における脳内タウ病変を単一症例ごとに評価可能な技術はこれまで存在しなかった。量研機構が開発した [18F]PM-PBB3は、3リピート、4リピート、3+4リピート型の幅広いタウオパチーを検出することが可能な唯一のタウPET薬剤である。本研究は、反復性軽度頭部外傷患者および健常者を対象として、次世代タウPET薬剤[18F]PM-PBB3を用いたPET検査を複数回行う縦断研究である。他にマルチモーダルMRI検査、神経心理検査、頭部打撃に関する指標の収集も行い、タウ蓄積量との関連を検討する。患者リクルートは、申請者が開設している慶應義塾大学病院の専門外来にて行う。

Outline of Final Research Achievements

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder associated with mild-repetitive traumatic brain injury. In this study, we performed PET scans with 11C-PiB and 18F-florzolotau, structual MRI, and blood biomarker measurements on 51 TBI patients (mean age 44.8 years, 36 with repetitive mild TBI and 13 with single severe TBI) and 27 healthy subjects (mean age 45.6 years). The repetitive mild TBI (professional boxer) group showed a significant increase in 18F-florzolotau compared to the healthy group in areas such as bilateral frontal lobes. 18F-florzolotau SUVR values in the gray matter positively correlated with cumulative brain damage and plama GFAP levels. We also assessed binding properties of 18F-florzolotau on CTE tau aggregates using human brain samples provided by Boston University.

Academic Significance and Societal Importance of the Research Achievements

TBIによって生じるさまざまな晩期後遺症の中でも反復性軽度頭部外傷によって引き起こされる慢性外傷性脳症(CTE)は、国内外で大きな問題となっているが、これまで早期診断法は存在しなかった。本研究は、18F-florzolotau を用いたPETがTBIによって引き起こされる脳内タウ蓄積を高精度に検出することを示し、慢性外傷性脳症の早期診断法の確立に大きく資する研究成果が得られ、予防や新規治療法の開発への応用が期待される。
