成熟的 BDNF 及其前体 proBDNF 在塑造神经元和为神经元连接的结构基础做出贡献方面发挥着至关重要的作用。它们以一种很大程度上相反的方式,通过与受体的不同接触来做到这一点。在这篇综述中,我们将总结 BDNF 通过控制神经元形态来调节中枢和周围神经系统内神经回路形成的证据。将描述将 BDNF 信号传导转化为神经元细胞形状变化的潜在细胞内机制。此外,还将讨论在 BDNF 作用位点局部起作用或长距离影响基因转录的信号传导途径。这些机制开始解释 BDNF 对神经元形态的作用的多样性。
Both mature BDNF and its precursor, proBDNF, play a crucial role in shaping neurons and contributing to the structural basis for neuronal connectivity. They do so in a largely opposing manner, and through differential engagement with their receptors. In this review, we will summarise the evidence that BDNF modulates neural circuit formation in vivo both within the central and peripheral nervous systems, through the control of neuronal morphology. The underlying intracellular mechanisms that translate BDNF signalling into changes of neuronal cell shape will be described. In addition, the signalling pathways that act either locally at the site of BDNF action, or over long distances to influence gene transcription will be discussed. These mechanisms begin to explain the diversity of actions that BDNF carries out on neuronal morphology.
