摘要
成年哺乳动物大脑仍然能够产生新生神经元的发现点燃了一个新的研究领域——神经发生。目前认为研究成年后的神经发生对进一步了解大脑功能和衰老，脑肿瘤、神经系统退行性疾病的发病机制和治疗，中枢神经系统的损伤修复等均具有重要的意义。成体神经发生是一个复杂的多步骤过程，每个阶段都受细胞内在基因表达程序和细胞外微环境因素的精细调控。越来越多的证据表明miRNAs代表了一类转录后基因表达调控因子，是控制成体神经发生的基因调控网络的重要组成部分。

Abstract
The finding that the adult mammalian brain is still capable of producing neurons has ignited a new field of research, namely neurogenesis. It is currently considered that the study of adult neurogenesis may contribute to further understanding of how to maintain the normal brain function and aging, pathogenesis and treatment of brain tumors, neurodegenerative diseases, as well as damage and repair of the central nervous system. In addition, adult neurogenesis is a complex multi-step process, each of which is finely regulated by cell-intrinsic gene expression and extra cellular microenvironmental factors. Accumulating evidence suggests miRNAs, which represent a class of post-transcriptional gene expression regulators, are a crucial part of the gene regulatory networks governing adult neurogenesis.
