放射状迷路
遅延非見本合わせ課題は、記憶保持に対する薬物の効果を調べるために(Pussinen, R.およびSirvio, J. J of Psychopharm 13:171-179(1999);Staubli, U.ら Proc Natl Acad Sci 91:777-781(1994))、8方向放射状迷路で使用されている。
8方向放射状迷路での習得
アルツハイマー病(AD)総体症状の顕著な初期特徴は、陳述記憶の著しい欠損である(R.W. Parks, R.F. ZecおよびR.S. Wilson編「Neuropsychology of Alzheimer's disease and other dementias」ニューヨーク:オクスフォード大学出版局, p. 3-80 (1993))。
細胞内カルシウムの機能的動員

機能的なGTP結合
細胞培養:ヒトM1−M5レセプターをトランスフェクトしたCHO細胞を、懸濁培養または単層培養のいずれかで増殖させた。懸濁培養に関しては、細胞をローラーボトルで絶えず攪拌しながら、37℃で5%CO2中で5%ウシ胎児血清、50μg/ml トブラマイシンおよび20mM HEPESを補充したダルベッコ改変イーグル培地/F−12(3:1)培養培地中で増殖させた。単層培養は、37℃で5%CO2でT−225フラスコ中10%ウシ胎児血清およびペニシリン/ストレプトマイシン(100,000U/リットル)を補充したダルベッコ改変イーグル培地を用いて増殖させた。95%コンフルエントでトリプシン不含解離培地を用いて細胞を集め、遠心分離により回収し、80℃で保存した。ヒトムスカリン性レセプターを安定に発現する細胞はNational Institutes of Healthから入手した。
