The appropriate utilisation, storage and conversion of nutrients in peripheral tissues, referred to as nutrient partitioning, is a fundamental process to adapt to nutritional and metabolic challenges and is thus critical for the maintenance of a healthy energy balance. Alterations in this process during nutrient excess can have deleterious effects on glucose and lipid homeostasis and contribute to the development of obesity and type 2 diabetes. Nutrient partitioning is a complex integrated process under the control of hormonal and neural signals. Neural control relies on the capacity of the brain to sense circulating metabolic signals and mount adaptive neuroendocrine and autonomic responses. This review aims to discuss the hypothalamic neurocircuits and molecular mechanisms controlling nutrient partitioning and their potential contribution to metabolic maladaptation and disease.
外周组织中营养素的适当利用、储存和转化,称为营养素分配,是适应营养和代谢挑战的基本过程,因此对于维持健康的能量平衡至关重要。在营养过剩期间,这个过程的改变会对葡萄糖和脂质稳态产生有害影响,并导致肥胖和 2 型糖尿病的发展。营养素分配是一个受激素和神经信号控制的复杂综合过程。神经控制依赖于大脑感知循环代谢信号的能力,并产生适应性神经内分泌和自主反应。本综述旨在讨论控制营养素分配的下丘脑神经回路和分子机制,及其对代谢适应不良和疾病的潜在贡献。
