microRNA(miRNAs)是一种小的19-23个核苷酸的调控RNA,其功能是以序列特异性方式调节mRNA的翻译和/或周转。在神经系统中,miRNA调节参与突触传递的许多蛋白质的产生。反过来,神经元活动可以通过多种机制调节miRNA的产生和周转。通过这种方式,miRNA和神经元活性处于平衡神经元功能的相互稳态关系中。miRNA的功能在与过度兴奋相关的病理状态如癫痫和中风中是至关重要的,这表明miRNA作为治疗靶点的潜力。我们回顾了目前有关miRNA与神经元活动相互作用的文献,并为确定miRNA在疾病中的作用提供了未来的方向。
MicroRNAs (miRNAs) are small 19–23 nucleotide regulatory RNAs that function by modulating mRNA translation and/or turnover in a sequence-specific fashion. In the nervous system, miRNAs regulate the production of numerous proteins involved in synaptic transmission. In turn, neuronal activity can regulate the production and turnover of miRNA through a variety of mechanisms. In this way, miRNAs and neuronal activity are in a reciprocal homeostatic relationship that balances neuronal function. The miRNA function is critical in pathological states related to overexcitation such as epilepsy and stroke, suggesting miRNA’s potential as a therapeutic target. We review the current literature relating the interplay of miRNA and neuronal activity and provide future directions for defining miRNA’s role in disease.
