自20多年前其初始表征以来,人们对理解转录因子cAMP反应元件结合蛋白(CREB)在神经系统生理学中的作用一直有着强烈而坚定的兴趣。通过一系列的实验方法和模型系统,研究人员已经开始解开这种转录因子在神经发育,突触可塑性和神经保护等不同过程中的复杂和多方面的作用。在这里,我们讨论了目前的分子机制,CREB夫妇突触活动的长期变化的神经元可塑性,这被认为是学习和记忆的基础。我们还讨论了CREB是神经保护性转录网络的重要组成部分的工作,以及CREB失调导致一系列神经病理学状况的数据。
Since its initial characterization over 20 years ago, there has been intense and unwavering interest in understanding the role of the transcription factor cAMP-responsive element binding protein (CREB) in a nervous system physiology. Through an array of experimental approaches and model systems, researchers have begun to unravel the complex and multifaceted role of this transcription factor in such diverse processes as neurodevelopment, synaptic plasticity, and neuroprotection. Here we discuss current insights into the molecular mechanisms by which CREB couples synaptic activity to long-term changes in neuronal plasticity, which is thought to underlie learning and memory. We also discuss work showing that CREB is a critical component of the neuroprotective transcriptional network, and data indicating that CREB dysregulation contributes to an array of neuropathological conditions.
