Cell Metab:什么脑细胞导致我们对糖的依赖?

2020-07-14 MedSci原创 MedSci原创

最近,研究人员确定了下丘脑中的FGF21的靶细胞,并揭示了FGF21向谷氨酸能神经元的信号传导是介导FGF21诱导的糖抑制和甜味偏好的必要和充分条件。

成纤维细胞生长因子21(FGF21)是一种由肝脏产生的内分泌激素,可调节营养和代谢平衡。FGF21的产生会在宏量营养素失衡的情况下增加,并向大脑发出信号,以抑制糖的摄入和甜味偏好。

然而,至今为止,我们对于介导这些效应的中心靶点一直不清楚。

最近,研究人员确定了下丘脑中的FGF21的靶细胞,并揭示了FGF21向谷氨酸能神经元的信号传导是介导FGF21诱导的糖抑制和甜味偏好的必要和充分条件。

此外,研究人员还发现FGF21直接作用于腹内侧下丘脑(VMH),特异性调节蔗糖摄入量,而不是非营养性甜味偏好、体重或能量消耗。

最后,该研究数据表明,FGF21通过增加VMH中神经元的激活和兴奋性来影响神经元的活动。

因此,FGF21向VMH中的谷氨酸能神经元发出信号是调节蔗糖摄入量的神经回路的重要组成部分。
