Nature Medicine:东南大学柴人杰团队等发布AAV基因治疗跨年龄遗传性耳聋患者的多中心临床试验结果
生物世界· 2025-07-03 02:04
撰文丨王聪 编辑丨王多鱼 排版丨水成文 耳聋 是人类最常见的感官障碍,先天性耳聋影响了全世界大约 2600 万人,其中高达 60% 的病例是由基因突变引起。 常染色体隐性遗传耳聋9型 ( DFNB9 ) ,是由 编码 耳畸蛋白 (Otoferlin) 的 OTOF 基因突变导致的感音神经性耳聋,占 遗传性耳聋的 2%-8%。耳畸蛋白能使内耳毛细胞响应声音刺激而释放神经 递质,激活听觉神经元,当其功能受损时,声音信号将无法被传达到大脑,从而导致感音神经性耳聋。 此前, 复旦大学附属眼耳鼻喉科医院 舒易来 教授 、 东南大学 附属中大医院 柴人杰 教授等 已经在低龄儿童患者中证实了 AAV 基因治疗 能够安全且有效地恢 复 DFNB9 患者的听力,相关研究发表于《 柳叶刀 》、 Nature Medicine 、 Advanced Science 等期刊。但还有一些关键科学问题亟待解答—— 大龄 DFNB9 患者是否能够受益于 AAV 基因疗法?是否存在最佳治疗年龄窗口? 2025 年 7 月 2 日 , 东南大学 附属中大医院 柴人杰 教授联合加州大学欧文分校 曾凡钢 教授,山东省第二人民医院 (山东省耳鼻喉医 ...
