中枢神经系统包括大脑的损伤后修复是目前医学及生物学领域的重大的前沿科学问题及难题。人类通常不能自发修复受损伤的中枢神经系统,并且目前缺乏有效的临床治疗手段。两栖类脊椎动物蝾螈(墨西哥钝口螈、Ambystoma mexicanum)具有强大的再生能力,其多种组织器官包括中枢神经系统、四肢等多种内外部组织器官在损伤后均可在细胞学水平及功能水平上完美再生修复。我们利用蝾螈为研究模型,以脊髓为研究对象,在细胞及分子生物学水平上探寻中枢神经系统损伤后的再生机制。为理解包括人类在内的哺乳动物脊髓损伤后修复的限制因素、重启哺乳动物脊髓损伤后细胞及功能水平上的修复提供可能的机制与可行的策略。目前,我们已建立了基于CRISPR-CAS9基因编辑技术的蝾螈基因敲除、脊髓神经干细胞组织特异性基因敲除,以及定点基因敲入等技术。参与并完成了蝾螈全基因组、及多种组织器官在不同发育时期和再生阶段的高通量转录组的序列测定与组装。 构建了研究中枢神经系统损伤修复所需的转基因动物及疾病模型,并初步鉴定了中枢神经系统再生的相关基因。教育经历09.1991-07.1994 山东省章丘市第七中学09.1994-07.1998 山东省莱阳农学院,植保专业,获农学学士学位09.1998-07.2001 华南农业大学,植物病理专业,获农学硕士学位09.2004-12.2008 德国马克斯-普朗克分子细胞生物学与遗传学研究所,获博士学位工作经历09.2001-08.2002 新加坡分子农业研究所 助理研究官08.2002-08.2004 新加坡淡马锡生命科学研究院 助理研究官01.2009-08.2009 德国马克斯-普朗克分子细胞生物学与遗传学研究所 博士后 09.2009-10.2016 德国德累斯顿再生治疗中心 博士后11.2016-至今 华南师范大学脑科学研究院,PI(研究员,博导)研究领域
