- histological evaluation also showed a reduction in inflammation in the HMGB1 peptide-administered group compared to the control group.
- the hepatocyte ballooning score was also significantly improved by administration of the HMGB1 peptide.
- the serum biochemical analysis showed a decrease in AST and ALT. This indicates that hepatocellular injury was reduced in the HMGB1 peptide-administered group as compared to the control group.
- a decrease in T-bil was observed in serum biochemical analysis. From this, it can be seen that liver dysfunction was also reduced in the HMGB1 peptide-administered group compared to the control group.

- the number of lipid droplets was significantly reduced in the HMGB1 peptide-administered group compared to the control group.
- the above results show that administration of the HMGB1 peptide improved the fatty liver itself.
- the T-Cho concentration was also decreased in the HMGB1 peptide-administered group compared to the control group. This suggests that administration of HMGB1 peptide also improves blood lipid status.
- Many therapeutic drugs for NASH improve liver inflammation and fibrosis, but there are few that improve fatty liver and blood lipids. Therefore, it can be said that the HMGB1 peptide can provide effects that are difficult to achieve with other NASH therapeutic agents.
- a pharmaceutical composition containing the peptide of the present application can be used as a therapeutic and/or prophylactic agent for various symptoms associated with fatty liver, non-alcoholic steatohepatitis, and fatty liver, for which existing therapeutic agents are not sufficiently effective. expected to be beneficial.

NASHモデルマウスに対するHMGB1断片ペプチドの有効性の評価
(1)材料および方法
i)薬剤調製
ヒト由来のHMGB1タンパク質のアミノ酸残基1-44(配列番号:1)からなるペプチドを固相法により化学合成した。以下、当該HMGB1断片ペプチドを単にHMGB1ペプチドと称し、図面では「HMGB1」と省略して表記する。また、後述のコントロール群を図面では「Control」と省略して表記する。
テキサス大学メディカルセンター Joel K Elmquistより、4型メラノコルチン受容体ノックアウトマウス(以下、「MC4R-KOマウス」とも称する。遺伝的バックグランド:C57BL/6J)の提供を受けた。
次いで、下記の文献に詳述されるように、MC4R-KOマウスに高脂肪食を与えることにより、マウスにNASHを誘導した。具体的には、図1に示すように、生後8週齢まではMC4R-KOマウスに普通食(ND)を与えた。その後、餌を普通食から高脂肪食(HFD)に切り替え、20週間高脂肪食を与え続けた。これにより、マウスにNASHを発症させた。
Itoh M, Suganami T, Nakagawa N, et al. Melanocortin 4 receptor-deficient mice as a novel mouse model of nonalcoholic steatohepatitis. Am J Pathol 2011;179:2454-63.
実験は、このマウスを、HMGB1ペプチド投与群(HMGB1投与群)とコントロール群(生理食塩水;NS投与;CTRL投与群)との二群に分けて行った。HMGB1投与群には、高脂肪食開始後16週から20週までの4週間、HMGB1ペプチドを週二回、5mg/kgの量で尾静注した。CTRL投与群には、高脂肪食開始後16週から20週までの4週間、生理食塩水を週二回、5ml/kgの量で尾静注した。
高脂肪食開始後20週経過時点でマウスを安楽死させ、マウスの心臓から動脈血を採取した。さらには、マウスの肝臓を採取した。そして、採取した血液、肝臓に対して以下の解析を行った。なお、以下の統計解析では、有意差は、全てt検定で求めた。
採取した動脈血におけるアスパラギン酸アミノトランスフェラーゼ(AST)、アラニン・アミノトランスフェラーゼ(ALT)、アルブミン(Alb)、総ビリルビン(T-bil)、総コレステロール(T-Cho)及び中性脂肪(TG)の血清濃度を、Oriental Yeast Co., Ltd. Nagahama LSL(Nagahama, Japan)が測定した。
b-1)HE染色およびSirius Red染色
採取した肝臓を、10%ホルマリンで固定し、厚さ4μmの切片を作成した。そして、これらの切片に対してヘマトキシリン・エオジン(HE)およびSirius Red染色を行った。肝臓組織の切片をHE染色し、顕微鏡で観察することにより、脂肪滴の有無やその割合を確認した。また、マウス一匹あたり10枚の顕微鏡写真をランダムに撮影し、画像解析ソフトを用いて、Sirius Redで染色された面積を測定した。
採取した肝臓を、10%ホルマリンで固定し、厚さ4μmの切片を作成した。この切片に対し、抗F4/80ウサギモノクローナル抗体(Abcam, Cambridge, UK)を用いて、免疫組織染色を行った。上記と同様に顕微鏡写真を撮影し、画像解析ソフトを用いて、抗F4/80抗体で染色された面積を測定した。
採取した肝組織20 mgをホモジナイズし、QuickZyme Hydroxyproline Assays (QuickZyme Bioscience, Zernikedreef, Netherlands)を用いて、試料中のヒドロキシプロリンの量を測定した。
得られた肝臓の組織染色に対して顕微鏡観察を行い、下記表1に示す基準に従って、肝組織における小葉の炎症と肝細胞の風船化を評価した。肝細胞に障害が発生すると、膨張して風船化する。したがって、風船化した肝細胞が多いと言うことは、障害を受けた肝細胞が多いことを意味する。

Design and validation of a histological scoring system for nonalcoholic fatty liver disease. Hepatology. 2005 Jun;41(6):1313-21.
i)体重、肝臓重量
図2上段左に高脂肪食開始後20週経過時点でのマウスの体重を、上段真ん中に肝臓重量を、上段右に肝体重比を示す。また、下段にHMGB1ペプチド投与開始後飼育完了までのマウスの体重変化を示す。これらの図に示すように、HMGB1ペプチド投与群とコントロール群とで、マウスの体重、肝臓重量、肝体重比、および体重変化のいずれにも、有意差が認められなかった(図中、「ns」と示す)。
図3上段左は血清中のAST濃度を、左から二番目はALT濃度を、右から二番目はAlb濃度を、右はT-bil濃度を示す。図3下段左はT-Cho濃度を、右はTG濃度を示す。コントロール群に比較してHMGB1ペプチド投与群では、AST, ALT, T-bil, T-Choの数値が、有意に低下(改善)した。
図4上段はHE染色の結果を、中段はF4/80免疫組織染色の結果を、下段はSirius Red染色の結果を示す。左側はコントロール群の顕微鏡写真であり、右側はHMGB1ペプチド投与群の顕微鏡写真である。HE染色では、HMGB1ペプチド投与群ではコントロール群に比較して、確認された肝細胞の脂肪滴の数が少なかった。すなわち、HMGB1ペプチド投与群ではコントロール群に比較して、脂肪滴の減少が確認された。F4/80免疫組織染色では、HMGB1ペプチド投与群ではコントロール群に比較して、染色された領域が小さく、F4/80陽性細胞の数が少なかった。Sirius Red染色では、HMGB1ペプチド投与群ではコントロール群に比較して、染色された領域が小さかった。
図5上段左はSirius Red陽性面積を、上段右はヒドロキシプロリンの定量結果を、下段はF4/80陽性面積を示す。HMGB1ペプチド投与群ではコントロール群に比較して、Sirius Red陽性面積、ヒドロキシプロリン量、およびF4/80陽性面積のいずれも、有意に低かった。
図6左は小葉の炎症の評価結果を、真ん中は肝細胞の風船化の評価結果を、右はNASを示す。HMGB1ペプチド投与群ではコントロール群に比較して、小葉の炎症のスコアも、肝細胞の風船化のスコアも、NASも有意に低かった。
i)肝臓の炎症と肝細胞・肝機能障害
F4/80は、マクロファージマーカーであることが知られている。図4中段および図5下段に示すように、HMGB1ペプチド投与群の肝組織ではコントロール群の肝組織に比べて、F4/80免疫組織染色によって染色された領域が小さく、F4/80陽性細胞の数も少なかったことから、NASHモデルマウスでは、HMGB1ペプチドの投与によって、炎症を惹起する細胞が減少したことが示唆される。加えて、図6左に示すように組織学的評価でも、HMGB1ペプチド投与群ではコントロール群に比べて、炎症の低減が認められた。さらに、図6真ん中に示すように、肝細胞の風船化のスコアもHMGB1ペプチドの投与によって有意に改善した。さらに、図3上段左および左から2番目に示すように、血清の生化学分析では、ASTやALTの低下が認められた。このことから、HMGB1ペプチド投与群ではコントロール群に比べて、肝細胞障害が軽減されたことが分かる。加えて、図3上段右に示すように、血清の生化学分析では、T-bilの低下が認められた。このことから、HMGB1ペプチド投与群では、コントロール群に比べて肝機能障害も軽減されたことが分かる。以上の結果から、HMGB1ペプチドは、NASHによる肝臓の炎症や肝細胞障害、肝機能障害を改善すると推定される。
Sirius Redは、I型・III型コラーゲンを染色することが知られており、線維化のマーカーとして用いられている。図4下および図5上段左に示すように、HMGB1ペプチド投与群の肝組織ではコントロール群の肝組織に比べて、Sirius Red染色によって染色された領域が小さかったことから、NASHモデルマウスでは、HMGB1ペプチドの投与によって、肝組織の線維化した部分が減少したことが示唆される。また、ヒドロキシプロリンは線維の前駆体のマーカーであることが知られている。ヒドロキシプロリン量の低下も、肝臓の線維化が低減したことを示唆している。以上の結果から、HMGB1ペプチドは、NASHによる肝臓の線維化を改善すると推定される。
図4上に示すように、HMGB1ペプチド投与群ではコントロール群に比較して、脂肪滴の数が顕著に減少した。以上の結果は、HMGB1ペプチドの投与によって、脂肪肝そのものが改善したことを示す。さらには、図3下段左に示すように、HMGB1ペプチド投与群ではコントロール群に比較して、T-Choの濃度も低下した。このことは、HMGB1ペプチドの投与によって、血中脂質の状態も改善することを示唆している。NASHの治療薬では、肝臓の炎症および線維化を改善するものが多いが、脂肪肝や血中脂質を改善するものは少ない。ゆえに、HMGB1ペプチドは、他のNASH治療薬では実現しにくい効果を提供できると言える。
