Description
本出願は、2016年7月26日に出願の米国特許仮出願第62/367,002号の優先権の利益を主張し、引用することにより本明細書の一部をなすものとする。
アルツハイマー病患者の家族および友人がほとんど毎日介護を行い、アルツハイマー病は、現在、我が国の経済総計で、年間3850億ドルかかるため、社会にも影響を及ぼしている。
アルツハイマー病対象は、University of Kansas Alzheimer’s Disease Center(ADC)によって募集された。ADCは、ルーチン的なキャラクタリゼーションが、臨床的認知症尺度(CDR)評定尺度、統一データセット(UDS)認知試験、およびAPOE遺伝子型判定を含む臨床コホートを維持する。クリニックコホートの参加者の診断は、主として、CDRおよびUDSデータに基づき、下位専門領域を訓練した認知神経内科医および熟練した神経心理学者を含む、コンセンサス会議によって決定される。アルツハイマー病と診断された対象は、McKhannら、Alzheimers Dement、7巻(2011号)263〜269頁における診断のための現在の基準を更に満たしている。
血液サンプルの取得および酵素活性の測定
血液サンプル40ミリリットルを、抗凝血薬として酸−クエン酸塩−デキストロース(ACD)管を含有する試験管に収集し、室温で維持した。静脈切開の24時間以内に、血液を、ADC Mitochondrial Genomics and Metabolism Coreにより処理した。プロセシング手順を開始するために、血小板を、遠心分離により単離し、濃縮されたミトコンドリア画分を、前述した方法を用いて調製した。かかる手順は、窒素キャビテーションを使用して、血小板を破裂させ、その後遠心分離し、ミトコンドリアを収集した。
アウトカム
血小板ミトコンドリアCOX活性のS−エコールに関連した改変を、主要アウトカム測度として設計した。個別の参加者の場合に、血小板ミトコンドリアのCOX活性のS−エコールに関連した変化が生じるか否かを決定するために、応答分析の想定されたパターンを用いた。血小板ミトコンドリアCOX活性が、積極的治療に応答して増加することが予想された。
APOE4保因者および非保因者のモントリオール認知評価(MoCA)
参加者合計16名を登録し、その中の15名の参加者は本試験を完了した。他の参加者から得られたデータを、いかなる分析においても含めなかった。15名の対象のうち、APOE4保因者は8名であり(7名がAPOE3/4遺伝子型であり、1名が、APOE2/4遺伝子型である)、および7名は、非−APOE4保因者である(全7名は、APOE3/3遺伝子型であった)。
APOE4保因者および非保因者のチトクロムオキシダーゼ(COX)およびクエン酸シンターゼ(CS)活性
COX活性をCS活性に参照することにより、それぞれアッセイしたサンプルについてのミトコンドリアの濃縮の程度を補正した後、参加者15名のうちの11名は、陽性の反応パターンを有することが判明した。
