Voltage-gated sodium channels (VGSCs) are fundamentally important for the generation and coordinated transmission of action potentials throughout the nervous system. It is, therefore, unsurprising that they have been shown to play a central role in the genesis and alleviation of epilepsy. Genetic studies on patients with epilepsy have identified more than 700 mutations among the genes that encode for VGSCs attesting to their role in pathogenesis. Further, many common antiepileptic drugs act on VGSCs to suppress seizure activity. Here, we present an account of the role of VGSCs in epilepsy, both through their pathogenic dysfunction and as targets for pharmacotherapy.
电压门控钠通道(VGSCs)对于整个神经系统中动作电位的产生和协调传导至关重要。因此,它们在癫痫的发生和缓解中发挥核心作用也就不足为奇了。对癫痫患者的遗传学研究已经在编码VGSCs的基因中鉴定出700多种突变,证明了它们在发病机制中的作用。此外,许多常用的抗癫痫药物作用于VGSCs以抑制癫痫发作活动。在此,我们通过VGSCs的致病性功能障碍以及作为药物治疗靶点两方面,阐述其在癫痫中的作用。
