Outline of Annual Research Achievements

Bdnf isoform 4,5,6,7を全身でノックダウンさせたマウスは過食になり太るので、餌報酬をもちいたオペラント行動で、野生型マウスと比較して高次脳機能を調べることが困難だった。CaMKII promoter-tTSマウスを用いて、前脳特異的にBdnf isoform 4,5,6,7をノックダウンさせたところ、マウスは過食にならず、体重増加もなかった。これによって、前脳特異的isoform 4,5,6,7ノックダウンマウスは、コントロールと比較して、餌報酬を用いたオペラント条件付けが可能になった。まず、注意、意欲、衝動性などのマウスの高次機能を広くスクリーニングできる3-choice serial reaction time taskをおこなった。残念ながら、いずれの行動指標にも変化は見られなかった。次に、インテリケージを用いた集団飼育で、delay discounting task、effort discounting taskをおこなった。ドキシサイクリンのオンとオフを組み合わせて、Bdnf遺伝子発現ノックダウンを時間制御しつつ、その影響を調べてみたものの、いずれのタスクにおいても、野生型と比較して優位な差を検出することができなかった。以上の結果から、ストレス負荷のない状態において、Bdnf発現低下は、マウスの認知機能、情動機能に大きな影響を与えないことが分かった。一方で、精神的ストレス負荷時には、Bdnf発現低下がストレスからの回復を阻害することから、Bdnfはストレス応答、ストレスレジリエンスにおいて、より積極的な役割を果たすことが明らかになった。
