孤束核(NTS)是参与心血管活动自主调节的形态和功能中心之一。表型特征的NTS神经元已被牵连在血压(BP)的差异调节。在这里,我们调查是否苯乙醇胺N-甲基转移酶(PNMT)表达的NTS(NTSPNMT)神经元有助于控制血压。我们证明,NTSPNMT神经元的光刺激对BP有不同的影响。在光遗传学刺激NTSPNMT神经元投射到下丘脑室旁核,外侧臂旁核和尾侧延髓腹外侧核的过程中产生了降压反应。相反,光刺激NTSPNMT神经元投射到延髓头端腹外侧产生了强大的升压反应和心动过缓。此外,NTSPNMT神经元和投射到延髓头端腹外侧的神经元的基因消融损害了动脉压力感受性反射。总之,我们揭示了神经元表型和电路的具体机制的NTSPNMT神经元的调节BP的贡献。
The nucleus tractus solitarii (NTS) is one of the morphologically and functionally defined centers that engage in the autonomic regulation of cardiovascular activity. Phenotypically-characterized NTS neurons have been implicated in the differential regulation of blood pressure (BP). Here, we investigated whether phenylethanolamine N-methyltransferase (PNMT)-expressing NTS (NTSPNMT) neurons contribute to the control of BP. We demonstrate that photostimulation of NTSPNMT neurons has variable effects on BP. A depressor response was produced during optogenetic stimulation of NTSPNMT neurons projecting to the paraventricular nucleus of the hypothalamus, lateral parabrachial nucleus, and caudal ventrolateral medulla. Conversely, photostimulation of NTSPNMT neurons projecting to the rostral ventrolateral medulla produced a robust pressor response and bradycardia. In addition, genetic ablation of both NTSPNMT neurons and those projecting to the rostral ventrolateral medulla impaired the arterial baroreflex. Overall, we revealed the neuronal phenotype- and circuit-specific mechanisms underlying the contribution of NTSPNMT neurons to the regulation of BP.
