STM :刺猬索尼克通路激动剂对抗唐氏综合症

2013-09-09 koo bio360

唐氏综合征(DS)是一种先天性染色体异常疾病,由于在减数分裂的后期,21号染色体未分离所致即所谓的21染色体三体,又被称为"21三体综合征"。患儿的主要临床特征为智能障碍、体格发育落后和特殊面容,并可伴有多发畸形。现在,来自约翰霍普金斯医学院(Johns Hopkins University School of Medicine)的研究人员识别出了一种蛋白质,能显著增强有类似唐氏综合症的实验鼠的学

唐氏综合征(DS)是一种先天性染色体异常疾病,由于在减数分裂的后期,21号染色体未分离所致即所谓的21染色体三体,又被称为"21三体综合征"。患儿的主要临床特征为智能障碍、体格发育落后和特殊面容,并可伴有多发畸形。

现在,来自约翰霍普金斯医学院(Johns Hopkins University School of Medicine)的研究人员识别出了一种蛋白质,能显著增强有类似唐氏综合症的实验鼠的学习和记忆能力。

根据发表在《科学-转化医学》期刊上的实验结果,单剂量治疗就能让老鼠的小脑成长到正常大小。【原文下载】

但科学家警告说,被称为刺猬索尼克通路激动剂(sonic hedgehog pathway agonist)的分子还没有在人类唐氏综合症患者身上证明安全,但认为有希望开发出相似的化合物。
