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。902Please respect copyright.PENANAkZ3adyDhqp

一直亦有不少研究試圖探討荷爾蒙與食慾的關係,902Please respect copyright.PENANAq0PAB7YVri
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。902Please respect copyright.PENANAyhI74z3cbd

(圖2)我們的食慾由下丘腦(Hypothalamus)所控制。902Please respect copyright.PENANAed2zy0uzaJ

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。902Please respect copyright.PENANAs6squOQ6bH

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。902Please respect copyright.PENANAYF6H1pbzHV

老鼠缺乏MC4R蛋白質的話,體重亦會明顯上升。902Please respect copyright.PENANAGeDY84bSxa
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。902Please respect copyright.PENANAUn0hRbvb17

(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。902Please respect copyright.PENANApIXduYLh62

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。902Please respect copyright.PENANAHkm2smyBJe
902Please respect copyright.PENANAuU4OpzuXCV
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。902Please respect copyright.PENANAsZhtJunsv4
