中枢阿黑皮素原(POMC)神经元形成了一个强有力的促肾上腺皮质激素网络,但我们对下丘脑回路在整个中枢神经系统(CNS)中的整合的理解仍然不完整。POMC神经元沿脑的吻尾轴沿着延伸投射,并且可以用POMC衍生的肽和快速氨基酸神经递质两者发出信号。虽然最近的实验进展,电路水平的操作已被应用到POMC神经元,许多关键的问题仍然存在:如何以及在哪里POMC神经元整合代谢信息?POMC神经元在什么条件下释放生物活性分子到整个CNS?从POMC神经元释放的GABA和谷氨酸或神经肽对调节摄食和代谢更重要吗?因此,解决在不同代谢条件下从POMC神经元诱发的信号的精确化学计量仍然是一项正在进行的奋进。在这篇综述中,我们分析了这个网络的解剖图谱并列POMC神经元在体外和体内的生理信号。我们还考虑新的遗传工具,以进一步表征POMC电路在体内的功能。我们的目标是综合POMC网络的全局视图,并突出需要进一步研究的差距,以扩大我们对这些神经元如何调节能量平衡的知识。
Central proopiomelanocortin (POMC) neurons form a potent anorexigenic network, but our understanding of the integration of this hypothalamic circuit throughout the central nervous system (CNS) remains incomplete. POMC neurons extend projections along the rostrocaudal axis of the brain, and can signal with both POMC-derived peptides and fast amino acid neurotransmitters. Although recent experimental advances in circuit-level manipulation have been applied to POMC neurons, many pivotal questions still remain: how and where do POMC neurons integrate metabolic information? Under what conditions do POMC neurons release bioactive molecules throughout the CNS? Are GABA and glutamate or neuropeptides released from POMC neurons more crucial for modulating feeding and metabolism? Resolving the exact stoichiometry of signals evoked from POMC neurons under different metabolic conditions therefore remains an ongoing endeavor. In this review, we analyze the anatomical atlas of this network juxtaposed to the physiological signaling of POMC neurons both in vitro and in vivo. We also consider novel genetic tools to further characterize the function of the POMC circuit in vivo. Our goal is to synthesize a global view of the POMC network, and to highlight gaps that require further research to expand our knowledge on how these neurons modulate energy balance.
