Research Abstract

継体培養可能なミュラー細胞(rMC-1)と網膜神経節細胞(RGC-5)を共培養した系を確立した.その系において,緑内障の発症因子のひとつであるグルタミン酸負荷をRGCに行い,ミュラー細胞が保護的に働くことを証明した.さらに,阻害剤を用いた実験から,ミュラー細胞に存在するグルタミン酸トランスポーターであるGLAST(EAAT-1)がから関与していることが示唆された.免疫染色によりGLASTがrMC-1に発現していることを確認した.また,RGC-5を用い,緑内障点眼剤として臨床使用されているラタノプロスト(LP),ならびに治験中のタフルプロスト(TP)の神経保護効果作用について検討した.RGC-5を用いたin vitro,視神経挫滅したラットを用いたin vivoの系でLP,TPともにRGC細胞死抑制効果をもつことが示唆された.
