肥胖已成为一个全球性的健康问题,但有效的治疗方法仍然非常有限。适应性产热通过以热的形式耗散能量来促进体重减轻,从而代表了对抗肥胖的有希望的目标。值得注意的是,产热的调节是由复杂的神经网络,特别是下丘脑中的神经网络紧密协调的。最近的证据强调了下丘脑腹内侧核(VMH)内腺苷一磷酸激活蛋白激酶(AMPK)在调节产热中的重要性。据报道,各种分子如GLP-1、瘦素、雌二醇和甲状腺激素作用于VMH以抑制AMPK,AMPK随后通过激活交感神经系统(SNS)增加产热。本文综述了AMPK在VMH能量平衡调控中的重要作用,重点介绍了AMPK在产热过程中的作用及其相关机制。
Obesity has become a global health issue, but effective therapies remain very limited. Adaptive thermogenesis promotes weight loss by dissipating energy in the form of heat, thereby representing a promising target to counteract obesity. Notably, the regulation of thermogenesis is tightly orchestrated by complex neuronal networks, especially those in the hypothalamus. Recent evidence highlights the importance of adenosine monophosphate-activated protein kinase (AMPK) within the ventromedial nucleus of the hypothalamus (VMH) in modulating thermogenesis. Various molecules, such as GLP-1, leptin, estradiol, and thyroid hormones, have been reported to act on the VMH to inhibit AMPK, which subsequently increases thermogenesis through the activation of the sympathetic nervous system (SNS). In this review, we summarize the critical role of AMPK within the VMH in the control of energy balance, focusing on its contribution to thermogenesis and the associated mechanisms.
