摘要
Epilepsy is a serious chronic neurologic disorder characterized by recurrent unprovoked seizures resulting from abnormal and highly synchronous neuronal discharges within the brain. Small noncoding RNAs, called microRNAs, play vital roles in epileptogenesis, with potential contributions as valuable biomarkers and targets for the treatment of epilepsy. To maintain cellular homeostasis, cellular components, such as organelles, proteins, protein complexes/oligomers, and pathogens, are delivered to the lysosome for degradation through a process called autophagy, which plays either a protective or a harmful role under epileptic stress. Several autophagic mechanisms have been implicated in epileptogenesis, including the mammalian target of rapamycin pathway, aberrant substrate accumulation, and the formation of epileptic networks. In addition, the regulation of autophagy through microRNAs (miRNAs) represents a novel posttranscriptional regulatory mechanism through 'autophagamiRNAs'. The correlation between autophagy and miRNA has increased our understanding of the underlying pathogenesis of human diseases. Here, we review the current findings regarding the correlations between miRNA, autophagy, and epilepsy to provide a solid foundation for further examination of the miRNA-autophagy pathway involved in epilepsy pathophysiology.
