在发育过程中,神经网络以高度有组织的方式建立,并在整个生命过程中持续存在。神经营养因子在神经系统发育中起着至关重要的作用。脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)是一种在脊椎动物进化过程中基因结构和功能高度保守的神经营养因子,在脑发育和突触可塑性中发挥重要作用。BDNF参与大脑中适当突触连接的形成,并且该过程中的中断有助于认知功能障碍。在这篇综述中,我们首先简要介绍了目前对BDNF的表达,调节和分泌的知识。此外,我们提供了一个概述的BDNF在神经回路的发展可能采取的行动,强调在中枢神经元的结构发育过程中的BDNF突触前行动。
During development, neural networks are established in a highly organized manner which persists throughout life. Neurotrophins play crucial roles in the developing nervous system. Among the neurotrophins, brain-derived neurotrophic factor (BDNF) is highly conserved in gene structure and function during vertebrate evolution, and serves an important role during brain development and in synaptic plasticity. BDNF participates in the formation of appropriate synaptic connections in the brain, and disruptions in this process contribute to disorders of cognitive function. In this review, we first briefly highlight current knowledge on the expression, regulation, and secretion of BDNF. Further, we provide an overview of the possible actions of BDNF in the development of neural circuits, with an emphasis on presynaptic actions of BDNF during the structural development of central neurons.
