Description
β25-35は容易に合成でき、科学研究で広く使用されている。そこで、本研究ではこのフラグメントを選択した。In vivoで、NTP投与後のAPP/PS1マウスの海馬における抗酸化物質の活性およびAβ沈着の変化を調べ、根底にある潜在的機序をさらに検討した。
本抽出物の基本的な抽出工程については、例えば、以下のような工程が用いられる。
HT22細胞の培養および分化に用いた方法は以前に詳しく報告した(Liu J, Li L, and Suo WZ. HT22 hippocampal neuronal cell line possesses functional cholinergic properties. Life Sci 2009;84:267-271.、Zhao ZY, Luan P, Huang SX, et al. Edaravone protects HT22 neurons from H2O2-induced Apoptosis by Inhibiting the MAPK Signaling Pathway. CNS Neurosci Ther 2013;19:163-169. 参照)。簡単には、10% FBS、100 U/mLペニシリン、および100 ug/mLストレプトマイシンを添加したDMEM培地でHT22細胞を培養し、処理前24時間にわたりN2サプリメントを添加した神経細胞用基礎培地で分化した。Aβ25-35を濃度0.5 mMの滅菌生理食塩水で希釈し、37℃で7日間保存してペプチドをプレエージング(pre-age)した。我々の以前の研究から(Fan S, Zhang B, Luan P, et al. PI3K/AKT/mTOR/p70S6K Pathway is involved in Aβ25-35-induced autophagy. Biomed Res Int 2015;2015:1-9. 参照)、HT22細胞を40 μMのAβ25-35に24時間曝露させるとHT22細胞の生存率は有意に低下する。そこで、その後の研究ではAβ25-35の最適濃度として40
μMを選択した。HT22細胞を規定用量のNTPで16時間前処理し、その後、40 μMのAβ25-35による24時間の処理を行うものと行わないものを用意した。
CCK-8アッセイを適用してHT22細胞の生存率を評価した。簡単には、それぞれの処理の後で、10 μL/wellのCCK-8試薬を細胞に添加し、その後、HT22細胞を暗条件下で37℃、CO2濃度5%で1.5時間インキュベートした。試料の吸光度を多機能マイクロプレートリーダー(SpectraMax M5、米国)により450 nmで測定した。
以前に報告した通り(Zhao ZY, Luan P, Huang SX, et al. Edaravone protects HT22 neurons from H2O2-induced Apoptosis by Inhibiting the MAPK Signaling Pathway. CNS Neurosci Ther 2013;19:163-169. 参照)、アネキシンV-FITCおよびPIアポトーシス検出キットを用いたフローサイトメトリー解析によりHT22細胞のアポトーシス細胞死を測定した。簡単には、HT22細胞をリン酸緩衝食塩液(PBS)で2回洗浄し、NTPの存在下または非存在下でAβ25-35に24時間曝露させた後、結合緩衝液中でアネキシンV-FITCおよびPIとともにインキュベートした。細胞懸濁液を用いてフローサイトメーター(FACSCalibur; BD、Franklin Lakes、NJ)によるフローサイトメトリー解析を行った。1試料あたり10000個の細胞を測定した。フローサイトメトリー解析と並行して、形態学的評価のためにHoechst 33342およびPIでの染色を行った。HT22細胞を4%パラホルムアルデヒドで10分間固定した。PBSで3回すすいだ後、細胞を5 mg/LのHoechst 33342と1 mg/LのPIで染色した。細胞を蛍光顕微鏡(BX51WI、Olympus、米国)下で観察した。
以前に報告した通り(Bao FX, Shi HY, Qi L, et al. Mitochondrial Membrane Potential-dependent Endoplasmic Reticulum Fragmentation is an Important Step in Neuritic Degeneration. CNS Neurosci Ther 2016; 22:648-660.参照)、酸化感受性蛍光プローブ(DCFH-DA)により細胞内ROSを測定した。簡単には、HT22細胞をNTPで16時間前処理した後、40 μMのAβ25-35に24時間曝露させた。処理後に、ピペッティングにより細胞を回収し、PBSで2回洗浄し、10 μMのDCFH-DAとともに37℃で20分間インキュベートした。FACSCaliburフローサイトメーターを使用して、1試料あたり10000個の細胞を検出した。陽性細胞における蛍光強度の幾何平均がROSの濃度を表す。また、蛍光顕微鏡下でもDCF蛍光強度を観察した。
JC-1によるミトコンドリア膜電位アッセイキットを用いて、製造者の指示に従ってMMPを推定した。処理後に、細胞をPBSで2回洗浄し、次に、5 μl/mLのJC-1により37℃で20分間染色した。JC-1染色緩衝液で2回すすいだ後、細胞懸濁液を回収し、フローサイトメーターを用いてMMPをモニターした。各試料について約10,000個の細胞をフローサイトメトリー解析に使用した。
6ヵ月齢の雄のAPP/PS1トランスジェニックマウスをJackson Laboratory(ME、米国)から入手し、餌および水を自由に摂取させた。本研究に使用したマウスはすべて、中山大学の動物実験委員会による承認を得たプロトコールに従って取り扱った。本研究の被験動物は、6ヵ月齢のAPP/PS1トランスジェニックマウス(TG、n=16)および野生型の同腹仔(WT、n=8)とした。NTP投与(TG+NTP)および対照(TG)のAPP/PS1トランスジェニックマウスならびに対照の野生型(WT)マウスの3群に動物を無作為に編成した。NTP投与群のマウスには、NTP(200 NU/kg/日)を3ヵ月間毎日強制経口投与した。残りのマウスにはプラセボ対照として生理食塩水(0.9% NaCl)を投与した。
スーパーオキシドジスムターゼ(SOD)、グルタチオン(GSH)およびカタラーゼ(CAT)の活性、ならびにマロンジアルデヒド(MDA)の含有量を、市販のキットを用いて、製造者の指示に従って測定した。海馬の組織を0.9%冷NaCl(9 mL)中で超音波処理によりホモジナイズし、4000 gで10分間、4℃で遠心分離し、上清を回収して、その後の解析のため80℃で保存した。上清中のタンパクレベルは、マイクロBCAタンパク質アッセイキットを用いて測定した。
以前に発表された方法を用いて(Schwab C, Steele JC, McGeer PL. Dystrophic neurites are associated with the majority of early stage extracellular neurofibrillary tangles in parkinsonism dementia complex of Guam. Acta Neuropathol 1997;94:486-492.、Schwab C, Hosokawa M, Mcgeer PL. Transgenic mice overexpressing amyloid beta protein are an incomplete model of alzheimer disease. Exp Neurol 2004;188:52-64. 参照)、固定切片のBielschowsky銀染色を行った。免疫組織化学染色については、製造者の指示に従い、ペルオキシダーゼ標識用にDABキットでマウスの脳切片を染色した。蛍光顕微鏡から画像を取得した。免疫組織化学染色で使用した一次抗体はマウス抗HIF-1α抗体(1:800;Abcam、MA、米国)である。Image Jソフトウェアを用いて老人斑およびHIF-1α陽性細胞の表面積を測定し、歯状回の割合として比較した。
処理後に、プロテアーゼ阻害剤カクテル溶液を添加した適切な量の沸騰させた変性用細胞溶解緩衝液(1% SDS、1 mM オルトバナジン酸ナトリウム、10 mM Tris-Cl、pH 7.4)でHT22細胞を溶解させた。マウスの海馬の試料タンパク質を迅速な免疫沈降アッセイ緩衝液(50 mM Tris[pH 7.4]、150 mM NaCl、1% Triton X-100、1%デオキシコール酸ナトリウム、0.1%ドデシル硫酸ナトリウム[SDS])中で抽出した。以前に報告した手順により 、ウエスタンブロット法および半定量解析を行った。使用した一次抗体と希釈率は以下の通りである:HIF-1α、1:2000;Bcl-2、1:1000;Bax、1:1000;Aβ1-42、1:1000;p-JNK、1:500;p-P38、1:500;p-ERK1/2、1:500;JNK、1:1000;P38、1:500;ERK1/2、1:2000;β-アクチン、1:1000。
データはすべて平均値±SEとして表し、すべての統計解析をSPSS 16.0ソフトウェア(SPSS Inc.、米国、IL、Chicago)を用いて行った。群間分散の解析には事後検定を伴う一元配置分散分析(ANOVA)を使用し、群間差はStudentのt検定を用いて比較した。P < 0.05で統計的に有意な差とみなした。
(i) NTPによるIn Vitroでの神経保護
図1に示すように、0.001~0.1 UN/mLの様々な濃度のNTPによる前処理によって、Aβ25-35により誘導される細胞毒性が抑制された(P < 0.05)。細胞のアポトーシスのフローサイトメトリー解析の結果、0.001~0.1 UN/mLのNTPを投与すると、Aβ25-35によって引き起こされる細胞のアポトーシスを有意に抑制できることが示された(P < 0.05)(図2A~F)。Hoechst 33342およびPI染色における蛍光顕微鏡でも同様の効果が認められた(図2G~K)。次に、NTPがROSレベルを低減するかどうかを調べた。NTPによる処理によってDCF蛍光強度の幾何平均が低下した。この効果は0.001 UN/mLと0.01 UN/mLの濃度では顕著に有意であったが、0.1 UN/mLの用量ではROS産生に有意差は認められなかったことから、高濃度のNTPは細胞内ROS産生の抑制に関して効果がない可能性が示唆された(図3A~F)。蛍光顕微鏡によるROSレベルの観察結果は、フローサイトメトリーで得られた結果と一致していた(図3G~K)。また、JC-1染色の結果、Aβ25-35群と比べて、0.01 NU/mL NTPによりミトコンドリア膜電位が減衰することが明らかとなった(図4A~D)。
次に、HT22細胞におけるAβ25-35に対するNTPの神経保護能の機序をさらに探索するため、HIF-1α、Bcl-2およびBaxのタンパク質発現を測定した。図4Eに示すように、ウエスタンブロット解析の結果、NTPはBcl-2の発現を有意に増強することが明らかになった。Bcl-2の誘導とは異なって、NTPはHIF-1αおよびBaxの発現を抑制した(P < 0.01)。
NTPを投与したAPP/PS1マウスの海馬における酸化ストレスマーカーを評価した。対照APP/PS1マウス群と比較して、NTPを投与したAPP/PS1マウスの海馬では、NTPの投与によってスーパーオキシドジスムターゼ(SOD)、カタラーゼ(CAT)、グルタチオン(GSH)のレベルが上昇し(それぞれP < 0.01、P < 0.05、P< 0.05)、マロンジアルデヒド(MDA)のレベルが減少した(P < 0.01)(Figure 5)。このことから、NTPは抗酸化系のバランスを制御する能力を示すことが示唆された。
APP/PS1マウスの海馬におけるAβ沈着に対するNTP投与の潜在的効果を調べるため、対照の野生型マウス、対照およびNTP投与のAPP/PS1マウスの海馬の冠状切片をBielschowsky銀染色を用いて確認し、Aβタンパクレベルの測定のため海馬組織を回収した。定量化解析の結果、NTP投与群ではAPP/PS1マウス群と比べてAβプラーク沈着物の表面積が有意に減少していた(図6A)(P < 0.01)。この結果と一致するように、NTP投与群の海馬ではAβ1-42タンパクレベルの低下が認められた(図6C)。
NTPの神経保護作用の根底にある機序をさらに検討するため、まず、免疫組織化学的染色およびウエスタンブロットにより海馬におけるHIF-1αの発現を検出した。その結果、NTPを投与したマウスではHIF-1αの発現が抑制されることが示された(図6B)(P < 0.05)。また、図6Cに示すように、ウエスタンブロット解析を使用してマイトジェン活性化プロテインキナーゼ(MAPK)経路の活性化も調べた。野生型群と比べて、APP/PS1マウスではERK1/2、JNK、およびP38のリン酸化が促進された。しかし、NTPの投与によってp-ERK1/2、p-JNKおよびp-P38の発現は顕著に減少した(P < 0.01)。
経路が活性化される可能性がある。Guo et al.によれば、神経芽細胞腫細胞において、MAPKシグナルはアニソマイシンによって活性化され、細胞内Aβ産生を誘導し得る。したがって、MAPKカスケードの調節不全は、ADにおけるAβと酸化ストレスの間の病理学的関連性をさらに裏付けるものである。本研究では、APP/PS1マウスにおいてERK1/2、JNK、およびP38の活性化亢進が認められた。しかし、NTPを投与したAPP/PS1マウスではMAPKの活性化が低下したことから、NTPによってリン酸化反応が抑制されることが示された。
以上を総括すると、本研究の結果では、Aβ25-35が、ROSレベルのアップレギュレーション、ミトコンドリア膜電位のダウンレギュレーションおよび細胞アポトーシスの亢進を含め、海馬の神経細胞損傷を誘導し得ることを示した。一方、NTPを投与することにより、HT22細胞においてAβ25-35により媒介された損傷を回復させた。また、NTPはAPP/PS1マウスの海馬におけるAβプラークの沈着を改善させ、抗酸化物質の活性を改変した。NTPの神経保護能はHIF-1αおよびMAPKシグナル伝達経路の抑制に関連する可能性が高い。つまり、NTPはラジカルスカベンジャーとしての役割を果たし、将来、ADの予防および治療に適用される可能性がある。
