NORMAL INTRAOCULAR PRESSURE GLAUCOMA MODEL AND EVALUATION METHOD OF PREVENTION OR THERAPEUTIC EFFECT FOR NORMAL INTRAOCULAR PRESSURE GLAUCOMA OF EVALUATION TARGET MEDICINE
To provide a glaucoma model being a useful model of the naturally-occurring normal intraocular pressure glaucoma, and an evaluation method of prevention or therapeutic effect for the normal intraocular pressure glaucoma of an evaluation target medicine, the method that is superior in clinical predictability.SOLUTION: A normal intraocular pressure glaucoma model comprises a non-human animal missing of ABCA1 genes. The model comprises the non-human animal missing of the present genes systemically or selectively in astrocyte/Muller cells. Also, an evaluation method of prevention or therapeutic effect for the normal intraocular pressure glaucoma of an evaluation target medicine comprises: a step of administering the evaluation target medicine to the normal intraocular pressure glaucoma model; and a step for evaluating that the evaluation target medicine has prevention or therapeutic effect for the normal intraocular pressure glaucoma, when an inhibitory effect to the detachment of retinal ganglion cells is significantly observed in comparison with the contrast administering a pharmacologically acceptable solvent instead of the evaluation target medicine, concerning the normal intraocular pressure glaucoma model after administering the evaluation target medicine.SELECTED DRAWING: Figure 2A【課題】自然発生型の正常眼圧緑内障の有用なモデルである緑内障モデル、及び臨床予見性に優れた、評価対象薬剤の正常眼圧緑内障予防及び治療効果の評価方法の提供。【解決手段】ABCA1遺伝子が欠損した非ヒト動物からなる正常眼圧緑内障モデルである。本遺伝子が全身性に、またはアストロサイト/ミューラー細胞選択的に欠損した非ヒト動物からなるモデルである。また、前記正常眼圧緑内障モデルに対し、評価対象薬剤を投与する工程と、前記評価対象薬剤を投与した後の前記正常眼圧緑内障モデルについて、網膜神経節細胞の脱落に対する抑制作用が、前記評価対象薬剤に代えて薬理学的に許容可能な溶媒を投与した対照と比較して有意に観察される場合に、前記評価対象薬剤に正常眼圧緑内障の予防乃至治療効果があると評価する工程とを含む評価対象薬剤の正常眼圧緑内障予防乃至治療効果の評価方法である。【選択図】図2A
