摘要
冷暴露是导致畜禽生产力低下的应激源之一,是负责非颤抖性产热的棕色脂肪组织(BAT)和诱导性棕色脂肪(iBAT)主要生理激活因子。下丘脑是机体脂肪储存和消耗中的主要控制中心。文章综述下丘脑不同区域和神经元参与调节白色脂肪组织(WAT)褐变和BAT产热的研究进展、下丘脑通过交感神经系统作用于脂肪细胞的腺苷酸活化蛋白激酶(AMPK)信号通路、调控脂肪细胞褐变及产热机理,旨在深入了解冷暴露下畜禽产热机制,为在生产中降低其维持能量、提高生产性能和动物福利水平提供参考。
Cold exposure is one of the stresses leading to low productivity in livestock.It is BAT and iBAT that are mainly responsible for non-shivering heat production.Hypothalamus is the main control center of fat storage and consumption.The paper reviews the regulation of the different regions and neurons of hypothalamus on WAT browning and BAT thermogenesis,and the regulation of hypothalamus through the action of sympathetic nervous system on the AMPK signal pathway to control adipocyte browning and thermogenesis,to deeply understand the thermogenesis mechanism of livestock under cold exposure,and to provide reference for reducing its maintenance energy and improving production performance and animal welfare.
