Bile acids facilitate dietary fat absorption upon release into the small intestine after a meal. A recent study by Liu and colleagues identifies a gut-brain axis wherein bile acids signal an energy-replete state to hypothalamic AgRP neurons via activation of neuronal FGF receptors, which orchestrate whole-body glucose metabolism.
胆汁酸在餐后被释放到小肠中，促进膳食脂肪吸收。最近，Liu 及其同事的一项研究确定了一个肠-脑轴，其中胆汁酸通过激活神经元 FGF 受体向下丘脑 AgRP 神经元发出能量充足的信号，从而协调全身葡萄糖代谢。
