文献概要
網膜の神経細胞においてニューロトロフィンは分化,成熟,生存のすべての過程において必須の因子である。ニューロトロフィンには神経成長因子(nerve growth factor:NGF),脳由来神経栄養因子(brain-derived neurotrophic factor:BDNF),ニューロトロフィン-3,-4(neurotrophin-3,-4:NT-3,NT-4)が属し,その受容体Trk(トラック)ファミリーを介してさまざまな生理活性を示す。そのなかでもBDNF-TrkBを介した反応が,網膜神経細胞にとって最も強力な作用を引き起こす。本稿では,BDNFの基礎知識から役割,最新の眼疾患の病態へのかかわりまでを広く紹介する。
