Research Abstract	(1)心筋症モデルを用いたHGFによる心筋線維化の阻止と心機能改善拡張型心筋症のモデルハムスターは生後26週から32週にかけて、心筋の線維化や肥大をもたらすTGF-β1やANPの発現増加と一致して心筋組織の繊維化と心機能の著しい低下を示した。これに対して、病態末期に近い27週目からHGFを3週間にわたり連日投与したところ、TGF-β1ならびにANPの発現抑制と心筋の線維化ならびに心機能の著しい改善が認められた。病態末期からの治療においてこのような治療効果が示された例はなく、HGFは拡張型心筋症に対する有効な治療法となるものと考えられる。 (2)HGFによる慢性腎不全の改善作用とその作用機構慢性腎不全はネフロン実質細胞傷害慢性的に引き起こされる典型的な線維性疾患である。慢性腎不全を自然発症するICGNマウスでは腎不全の進行に伴いTGF-βの発現が著しく増加するが、コラーゲンレペル、尿細管のアポトーシスはTGF-βとよく相関して増加した。一方、HGFの発現はTGF-βと相反的に減少の一途をたどり、尿細管の再生はHGFレベルとよく相関した。ICGNマウスに抗HGF抗体を投与すると、腎臓におけるTGF-βレベルは増加し、これと相関して、コラーゲンの蓄積、尿細管のアポトーシスが増加する一方、尿細管の再生は強く抑制された。したがってHGFはTGF-βと拮抗し慢性腎不全の進行を抑制するように機能していると考えられる。 (3)肺線維症ブレオマイシン投与により誘発させた肺線維症のモデルにおいてTGF-beta1の発現誘導とともにコラーゲン沈着が進行し、組織線維化が増悪された。一方、内因性HGFの発現は初期では高まるが、繊維化が高まるにつれ、著しく抑制されることも明らかとなった。そこでブレオマイシン処理したマウスにHGFの中和抗体を投与すると、実質組織の破壊に一致して線維化が加速されることが明らかとなった。組織線維化において中心的な役割を担うとされる筋線維芽細胞にはHGF受容体であるc-Metが発現しており、HGF刺激によってアポトーシスに陥ることも明らかとなった。
