摘要
孤束核是接收并整合心血管调节信号传入的第一级中枢,其通过参与心血管反射,在维持正常自主神经活动及血压调节中发挥重要作用。孤束核内的神经元之间形成复杂的突触连接,并与其他脑区相互作用。孤束核通过压力感受器反射、交感神经活动、肾素-血管紧张素-醛固酮系统和氧化应激等多种途径调节自主神经活动及血压。孤束核功能异常可能导致高血压。研究孤束核在血压中枢调控的作用,以及干预孤束核相关的神经递质和信号通路,可为高血压的防治提供新思路。本文总结了迄今为止有关孤束核调节自主神经活动及血压的研究结果和亟待解决的问题,旨在为今后研究提供参考和借鉴。
The nucleus tractus solitarius(NTS)is the primary brain region for receiving and integrating cardiovascular afferent signals.It plays a crucial role in maintaining balance of autonomic nervous system and regulating blood pressure through cardiovascular reflexes.Neurons within the NTS form complex synaptic connections and interact reciprocally with other brain regions.The NTS regulates autonomic nervous system activity and arterial blood pressure through modulating baroreflex,sympathetic nerve activity,renin-angiotensin-aldosterone system,and oxidative stress.Dysfunctions in NTS activity may contribute to hypertension.Understanding the NTS'role in centrally regulating blood pressure and alterations of neurotransmission or signaling pathways in the NTS may provide rationale for new therapeutic strategies of prevention and treatment.This review summarizes the research findings on autonomic nervous system regulation and arterial blood pressure control by NTS,as well as unresolved questions,in order to provide reference for future investigation.
