去甲肾上腺素通路的研究进展及其在迷走神经电刺激改善难治性癫痫学习记忆中的潜在作用
摘 要:
迷走神经电刺激(vagus nerve stimulation, VNS) 对无法手术的耐药难治性癫痫患者能起到较好的抗癫痫效果,目前已被美国FDA 批准用于耐药难治性癫痫的临床辅助性治疗。VNS 的抗癫痫作用可长期维持,且治疗效果随刺激时间的延长而增加。有研究发现,VNS 在减少癫痫发作的同时,还能改善癫痫患者的情绪状态,提高患者的认知能力。去甲肾上腺素能系统参与突触可塑性调节。本文综述了VNS 改善难治性癫痫患者学习记忆能力的研究进展,重点讨论了去甲肾上腺素能系统调控突触可塑性变化的相关信号通路,提出VNS 激活去甲肾上腺素能系统从而改善患者学习记忆的潜在可能性,为临床癫痫治疗提供新的靶点和
思路。

Abstract:
Vagus nerve stimulation (VNS) has shown an obvious anti-epileptic effect on patients with drug-resistant refractory epilepsy (DRE) and has been approved by the US FDA to clinically treat DRE as a supplementary approach. The antiepileptic effect of VNS could be maintained for a long time and strengthened by increasing the duration of electrical stimulation. More and more studies have shown that VNS not only reduces seizures but also improves the emotional state and cognition of epileptic patients. The norepinephrine (NE) system is involved in synaptic plasticity regulation. In this review, we summarize the recent progress of VNS in improving the learning and memory ability of DRE patients and introduce the main signaling pathways of the NE system in regulating synaptic plasticity. Further, we propose a potential possibility of improving learning and memory by activating the NE system in DRE patients after VNS treatment, which provides a new target and thinking basis for clinical epilepsy treatment.
