王以政博士1982年毕业于中国医科大学,1985获中国军事医学科学院硕士学位,1991在加拿大 Laval 大学获生物化学和实验医学博士。1991年至1994年分别在美国 Case Western Reserve 大学和法国 Nice 大学从事博士后工作。1995年至2001年先后在加拿大National Research Council 和美国 Thomas Jefferson 大学任职,主要研究谷氨酰胺的信号传导通路与神经元存活和死亡的机制等,其主要研究成果发表在《Nature》等国际著名学术杂志上。2001年8月回国后,任中国科学院神经科学研究所神经信号转导研究组组长,研究员,博士生导师,所教育委员会委员、所科研计划委员会委员等职。
王以政博士是中国科学院“杰出人才基金”(2001-2003)、“国家杰出青年基金”(2003- 2006)获得者。“国家重点基础研究发展规划--脑发育和可塑性的基础研究(2002- 2005)”项目的子课题的负责人。
研究方向
凋亡在正常发育过程中,以及许多病理情况下发挥重要作用,如:小脑发育、中风(stroke)、脊柱损伤和某些神经退行性疾病等。凋亡作为一种普遍的生物现象,在被深入研究的同时,仍存在大量未知领域:在中风这一具体病理条件下,神经元是如何遭受刺激,进而产生凋亡的?本研究组主要关注神经细胞凋亡机制研究,着重阐明胞内离子、以及对应离子通道同凋亡之间的关系;重点探索兴奋性毒诱导神经元凋亡的新机制,希望找出能够抑制兴奋性毒引起神经元凋亡的新靶点。离子通道的激活,尤其是下游信号通路级联事件的发生直接影响到神经元的存活。本研究组正在进行的课题包括:TRP (transient receptor potential) 通道和钾通道在神经元存活、分化以及细胞增殖过程中的作用;涵盖了从分子、细胞到整体,由机制到功能的研究,具体手段包含:分子生物学、细胞生物学、生物化学、电生理、原代神经元培养以及在体动物实验。从分子机制到整体功能的研究结果将丰富人们对神经元存活的理解,并在此基础上揭示临床运用价值。
