一种帕金森药可安全减缓ALS症状进展
帕金森 干细胞 肌萎缩性侧索硬化症 渐冻症
2023/6/2
日本科学家的一项早期临床试验发现，帕金森药物罗匹尼罗对ALS患者是安全的，平均可将ALS进展延迟27.9周。甚至，一些患者对罗匹尼罗治疗的反应比其他患者更好。此外，研究人员能够利用患者干细胞衍生的运动神经元在体外预测临床反应。相关研究6月1日发表于《细胞—干细胞》杂志。
使用一种实验性药物，研究人员能够抑制一种突变肌萎缩性侧索硬化症(ALS)基因。在小鼠身上的研究表明，这种疗法是可行的显示出治疗由融合肉瘤基因(FUS)突变引起的罕见、侵袭性ALS的希望。这项研究发表在Nature Medicine，美国国立卫生研究院(National Institutes of Health)下属的国立神经疾病和中风研究所(National Institute for Neuro...
科技日报北京2021年12月29日电 （记者张梦然）据物理学家组织网近日报道，澳大利亚62岁的肌萎缩侧索硬化症（ALS）患者菲利普·奥基夫最近成为第一个仅用自己的想法在社交媒体上发布消息的人。12月23日，他在推特上发布了一条简短的消息“你好，世界”（Hello World）。
肌萎缩侧索硬化症（Amyotrophic lateral sclerosis, ALS）俗称渐冻症，是一种以脑运动皮质、脑干和脊髓运动神经元退行性改变为特征的进行性麻痹行疾病，其临床表现主要为逐渐加重的肌肉无力、萎缩、肌束震颤、延髓麻痹及椎体损害，最终导致吞咽困难，呼吸肌无力而死亡。ALS的核心病理改变为运动皮质及脊髓运动神经元凋亡，伴随有星形胶质细胞、小胶质细胞及少突胶质细胞增生的神经炎症反应。...
