摘要: 肥胖是当今全球范围内十分突出、危害极大的公共卫生危机,其实质上是能量摄入与消耗长期失衡的结果,与此直接相关的有中枢摄食调控、脂肪组织代谢及全身炎症反应诸种复杂网络。自噬是一种高度保守、功能明确的细胞内降解途径,能清除受损细胞器、蛋白聚集体及脂滴,因而天然参与能量回收及代谢调控。具体而言,在脂肪组织中,自噬在白色脂肪中促进脂肪生成及脂质储存,在棕色/米色脂肪中参与线粒体清除及白化过程,调节产热功能,同时在脂肪组织巨噬细胞中通过降低线粒体活性氧、抑制NLRP3炎症小体活化来弱化促炎反应,从而调控组织炎症。更为重要的是,下丘脑POMC和AgRP神经元中的自噬可直接调控神经肽的加工、分泌,是中枢控制食欲及能量消耗极为重要的分子开关。肥胖相关自噬基因在脂肪生成、产热调控、炎症反应及神经元功能中都具有明确而关键的作用,其失调必然导致脂质堆积、胰岛素抵抗及慢性炎症,形成中枢-外周相互强化的代谢紊乱网络。正因如此,基于自噬调控机制的营养干预、药理激活及miRNA介导的精准干预都显示出改善肥胖及相关代谢紊乱的巨大潜力。因此,系统、严谨地厘清自噬在脂肪组织、中枢神经系统及全身代谢调控中的作用,有利于从分子层面阐明肥胖的机制,从而设计有效的组织特异性干预策略。

Abstract: Obesity is a prominent and highly detrimental public health crisis worldwide.Its essence lies in a chronic imbalance between energy intake and expenditure,directly involving complex networks of central appetite regulation,adipose tissue metabolism,and systemic inflammation.Autophagy is a highly conserved and well-defined intracellular degradation pathway that clears damaged organelles,protein aggregates,and lipid droplets,thereby intrinsically participating in energy recycling and metabolic regulation.Specifically,in adipose tissue,autophagy promotes adipogenesis and lipid storage in white adipose tissue,participates in mitochondrial clearance and the whitening process in brown/beige adipose tissue to modulate thermogenesis,and attenuates pro-inflammatory responses in adipose tissue macrophages by reducing mitochondrial reactive oxygen species and inhibiting NLRP3 inflammasome activation,thereby regulating tissue inflammation.More importantly,autophagy in hypothalamic POMC and AgRP neurons directly regulates neuropeptide processing and secretion,thus serving as a critical molecular switch for central control of appetite and energy expenditure.Obesity-related autophagy genes play clear and essential roles in adipogenesis,thermogenic regulation,inflammatory responses,and neuronal function;their dysregulation inevitably leads to lipid accumulation,insulin resistance,and chronic inflammation,forming a central-peripheral,mutually reinforcing network of metabolic dysregulation.Consequently,nutritional interventions,pharmacological activation,and miRNA-mediated precision interventions based on autophagic regulatory mechanisms all show great promise for ameliorating obesity and related metabolic disorders.Therefore,systematically and rigorously elucidating the role of autophagy in adipose tissue,the central nervous system,and systemic metabolic regulation will help clarify the molecular mechanisms underlying obesity and,more importantly,facilitate the design of effective tissue-specific intervention strategies.
