減低食慾從而減少進食,某程度上亦可看成為對抗肥胖或癡肥的其中一道方法。900Please respect copyright.PENANA2WNGceiYKt

一直亦有不少研究試圖探討荷爾蒙與食慾的關係,900Please respect copyright.PENANAynJK3Vg15f
其中之一的目標就是設計出一款能壓抑食慾的藥物,輔助癡肥或糖尿病人的治療。900Please respect copyright.PENANAZf6aeGS1ku

以非常簡化的角度來說,在飽肚狀態下,含有MC4R蛋白質的神經細胞便會受到刺激,我們的食慾亦會隨之受到壓抑。900Please respect copyright.PENANAP4wnSZojjz

相反,在飢餓狀態下,含有MC4R蛋白質的神經細胞便會受到壓抑,我們的食慾亦會隨之而來。900Please respect copyright.PENANAKTvJPXcmbX

老鼠缺乏MC4R蛋白質的話,體重亦會明顯上升。900Please respect copyright.PENANAVLGDTIKFKp
而MC4R的蛋白質因基因變異而導致部份功能的喪失,亦能在不少癡肥人士身上記錄得到。900Please respect copyright.PENANACUME3VN6nm

(圖3)刺激MC4R,便能減低食慾,減低食慾,便能減低進食量,有助對抗癡肥。900Please respect copyright.PENANARlNuoxZAPx

第一代刺激MC4R的藥物基於其附帶的血壓上升副作用,不得不終止研究及停止發展。900Please respect copyright.PENANAukR4dDij49
900Please respect copyright.PENANAbviq1iGiYn
而好消息的是,最近(2020年11月)FDA批准了新一代刺激MC4R的藥物Setmelanotide,並沒有血壓上升的副作用,在符合對應的條件下可用作體重管理之用。900Please respect copyright.PENANAHXzuzNZAf0
