AMPA受体(AMPAR)介导大脑中大部分快速兴奋性突触传递。神经元突触效能的动态变化,称为突触可塑性,被认为是学习和记忆中信息编码和存储的基础。调节突触强度的一个主要机制涉及AMPAR进出突触的严格调节的运输。AMPAR从其生物合成、膜运输和突触靶向到其降解的生命周期由与许多细胞内调节蛋白的一系列协调的相互作用控制。在这里,我们回顾了最近取得的进展,了解AMPAR运输的调控,重点是几个关键的细胞内AMPAR相互作用蛋白的作用。
AMPA receptors (AMPARs) mediate the majority of fast excitatory synaptic transmission in the brain. Dynamic changes in neuronal synaptic efficacy, termed synaptic plasticity, are thought to underlie information coding and storage in learning and memory. One major mechanism that regulates synaptic strength involves the tightly regulated trafficking of AMPARs into and out of synapses. The life cycle of AMPARs from their biosynthesis, membrane trafficking and synaptic targeting to their degradation are controlled by a series of orchestrated interactions with numerous intracellular regulatory proteins. Here we review recent progress made towards the understanding the regulation of AMPAR trafficking, focusing on the roles of several key intracellular AMPAR interacting proteins.
