ITGA11およびcalcium- and integrin-binding protein 1(CIB1)を高発現させた細胞はTGF-βに対する感受性が亢進した. また, 緑茶成分epigallocatechin-3-gallate (EGCG)はTGF-βtype IIレセプターに結合し, TGF-βの作用を阻害することが判明した. 研究成果の概要(英文): When corneal fibroblast (keratocyte) was stimulated by TGF-beta, the keratocytes showed myofibroblast-like morphology. In addition, the expression of integrin alpha11 (ITGA11), alpha-smooth muscle actin (alpha-SMA), fibronectin in keratocytes was increased by TGF-beta treatment. Sensitivity to TGF-beta was up-regulated in the cells constitutively expressing ITGA11 or calcium-and integrin-binding protein 1. It was suggested that ITGA11 and CIB1 could be the target protein of the organ fibrosis treatment. Furthermore, we found that the green tea component epigallocatechin-3-gallate (EGCG) binds to TGF-beta type II receptor and inhibits the action of TGF-beta., 研究種目:基盤研究(C); 研究期間:2011~2013; 課題番号:23592596; 研究分野:医歯薬学; 科研費の分科・細目:外科系臨床医学・眼科学, application/pdf}, title = {眼創傷治癒におけるTGF‐βとインテグリンの相互作用の役割解明とその応用}, year = {2013}, yomi = {ヨシダ, コウジ and スギオカ, コウジ and ハギハラ, サトル} }
