サマリー

頭痛性中風(IS)後の血液脳関門の修復メカニズムに対するHXRLFの効果を調査することを目的とする。方法は、オスC57BL/6マウスを偽手術(Sham)グループ、脳梗塞モデル(MCAO)グループ、昼夜リズム紊乱併発脳梗塞モデル(ECD-MCAO)グループ、HXRLFの低、中、高用量(HXRLF-L、M、H)グループ(8.5、17、34 g・kg−1・d−1)、陽性薬物NBPグループ(0.23 mL・d-1)にランダムに分け、Shamグループは血管を分離露出させるだけで縫い針に挿しこまない。他の各グループはマウスの脳中動脈閉塞(MCAO)モデルを作成し、ECD-MCAOグループ、HXRLFの各用量グループ、NBPグループは環境生物リズム紊乱(ECD)モデルを作成する。Shamグループ、MCAOグループ、ECD-MCAOグループのマウスに等体積大豆油を胃管投与し、他の各グループには対応薬剤を胃管投与し、各グループに7日間連続投与し材料を取る。mNSS評価によってHXRLFがIS後の神経系欠損の修復作用を評価し、HE染色評価によってHXRLFがIS後の脳組織病理学的損傷への影響を評価し、TTC染色と脳血流投注状態評価によってHXRLFがIS後の脳組織損傷の修復作用を評価し、エチドブルー染色と透過電子顕微鏡によってHXRLFがIS後の血液脳関門透過性損傷の改善作用を評価し、免疫蛍光(IF)染色で脳組織内血管性血友病因子(vWF)、脳と筋肉芳香炭素受容体核転写因子様タンパク質-1遺伝子(Bmal1)、結合タンパク質(Occludin)の発現を観察した。Western blot検査でBmal1、Occludin、接合タンパク質(Claudin-5)、血管内皮成長因子(VEGF)、血管生成素(Ang)のタンパク質発現を検査して関連分析を行った。結果は、Shamグループと比較して、MCAOグループでは神経機能欠損、脳梗塞体積、脳病理学的損傷、BBB漏出が著しく増加し、脳血流投注が著しく減少し、脳組織内Bmal1、vWF、VEGFA、Ang発現が著しく増加し、Occludin、Claudin-5発現が著しく減少する。MCAOグループと比較して、ECD-MCAOグループでは神経機能欠損、脳梗塞体積、BBB漏出が著しく増加し、脳病理学的損傷が著しく増加し、脳血流投注が著しく減少し、脳組織内Bmal1、vWF、VEGFA、Ang、Occludin、Claudin-5発現が著しく減少する。ECD-MCAOグループと比較して、HXRLF各用量グループは神経機能欠損、脳梗塞体積、脳病理学的損傷、BBB漏出が著しく改善し、脳血流投注が著しく増加し、脳組織内Bmal1、vWF、VEGFA、Ang、Occludin、Claudin-5の発現レベルが著しく増加した。結論HXRLFは生物時計タンパクBmal1を調整し、VEGFA、Ang、Occludin、Claudin-5発現を促進し、痛風性中風後の血液脳関門のダメージを改善する。
