An enzymatic digest of ovalbumin (30 mg/kg/day) was orally administered for 3 days from days 5 to 7 during the week in which the mice were fed the high-fat diet.

- ORT consists of three steps (Habituation, Acquisition (Trial 1), Testing (Trial 2)).
- a habituation step was performed on day 6 by leaving the mice in the square open field for 5 minutes.
- An acquisition step was then performed 24 hours after the habituation step.
- the acquisition step was performed by placing the mouse in an open field with two identical objects.
- a test step was performed 1 hour after the acquisition step. In the test step, one of the two identical objects was replaced with a new object.
- the proportion of time spent exploring the novel object in the test step was evaluated. Increased cognitive function was determined when the proportion of time spent exploring novel objects increased. The results are shown in FIG.
- the ORT test was performed in the same manner as described above, except that the following peptides (3 mg/kg/day (2 mg/kg/day for LEQ only)) were used instead of the enzymatic digest of ovalbumin.

20mg/mLのオボアルブミン(Albumin from chicken egg white lyophilized powder(Sigma-Aldrich社製))水溶液をボイルしたのちにサーモリシン(ナカライテスク社製))をE/S(酵素/基質)=l/100となるように加え37℃で5時間消化した。なお、反応中はpHが7.5となるように調整した。反応終了後、再びボイルし酵素反応を停止させ、遠心分離し、その上清を凍結乾燥した。
雄性ddYマウス11週齢(日本SLC)を12時間明暗サイクルに設定された飼養保管施設で1週間予備飼育した。次に、前記マウスに高脂肪食(HFD)として60%kcal飼料(D12492、ResearchDiets)を1週間摂取させたのちに行動試験を実施した。なお、マウスに高脂肪食を摂取させた1週間のなかで、5~7日目の3日間にわたりオボアルブミンの酵素消化物(30mg/kg/day)を経口投与した。
認知機能はORTで評価した(非特許文献1、Leger et al., Nat Protoc. 2013 Dec;8(12):2531-7.)。ORTは3つのステップ(馴化(Habituation)、獲得(Trial 1)、テスト(Trial 2))から構成される。馴化ステップは6日目に、マウスを角型オープンフィールドに5分間放置することにより実施した。次に、馴化ステップの24時間後に獲得ステップを実施した。獲得ステップは、2つの同一物体を置いたオープンフィールドにマウスを入れることにより実施した。さらに、獲得ステップの1時間後にテストステップを実施した。テストステップにおいては、2つの同一物体のうち1つを新しい物体に置き換えた。マウスのそれぞれの物体への接近時間をもとに、テストステップにおける新奇物体への探索時間の割合を評価した。新奇物体への探索時間の割合が増加した場合に、認知機能が上昇したと判定した。結果を図2に示す。
用いたペプチドは、アミノ酸配列ILPEY(配列番号1)からなるペプチド、アミノ酸配列LEQからなるペプチド、アミノ酸配列ILELP(配列番号2)からなるペプチド、アミノ酸配列LYRGGLEP(配列番号3)からなるペプチド、アミノ酸配列LPEY(配列番号4)からなるペプチド、アミノ酸配列ILPE(配列番号5)からなるペプチド、アミノ酸配列LPEからなるペプチド、アミノ酸配列LPからなるペプチド、アミノ酸配列LEPからなるペプチド、及びアミノ酸配列LEからなるペプチドである。
