摘要 目的:综述脑发育过程中细胞凋亡的分子机制。资料来源:通过计算机检索了MEDLINE2000-01/2004-12英文文献,并对部分所选文章的参考文献进行了二次检索。MEDLINE检索的主题词包括“apoptosis,programmedcelldeath,braindevelopment,neurode-velopment”。资料选择:纳入标准:有关脑发育过程中细胞凋亡分子机制的研究。排除标准:①有关成熟神经系统中细胞凋亡分子调节方面的研究。②文献中重复研究、综述、Meta分析类文章。资料提炼:在104篇检索出来的文献中,63篇与主题相关,再根据综述研究的目的选取了其中的26篇。资料综合:胚脑中细胞凋亡的发生被认识后,细胞凋亡对正常神经系统发育和功能的重要意义就成为神经科学研究的一个主要焦点,并在细胞凋亡调控方面的研究取得了显著进展。调节华美新小杆线虫和哺乳动物细胞凋亡的分子具有广泛的同源性;并且,Bcl-2和半胱氨酸天冬氨酸蛋白酶家族成员的靶基因断裂技术表明,bcl-x,bax,半胱氨酸天冬氨酸蛋白酶9和半胱氨酸天冬氨酸蛋白酶3在哺乳动物脑发育过程中起特别重要的作用。结论:细胞凋亡在正常和异常脑发育过程中均起着非常重要的作用。明确脑发育过程中有关细胞凋亡调节的分子通路可深入地了解脑形态发生学和脑畸形的发生机制。 OBJECTIVE:To review the molecular mechanisms of apoptosis in brain development. DATA SOURCES:A search for the English language articles between January 2000 and December 2004 was performed in MEDLINE by using computer,and the references of partial articles were retrieved for the second time.Theused in the MEDLINE search were apoptosis,programmed cell death,brain development and neurodevelopment. STUDY SELECTION:The studies on molecular mechanisms of apoptosis in brain development were included,but those related to molecules regulat
