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。901Please respect copyright.PENANAcmSCTDsuER

一直亦有不少研究試圖探討荷爾蒙與食慾的關係,901Please respect copyright.PENANAZhl1j8HeWr
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。901Please respect copyright.PENANAt3Tfb2GVlx

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。901Please respect copyright.PENANAuF6RVut3pK

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。901Please respect copyright.PENANANMgPaRF4zu

老鼠缺乏MC4R蛋白質的話,體重亦會明顯上升。901Please respect copyright.PENANAVNpqpxoEXd
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。901Please respect copyright.PENANAGLwBtJeRaB

(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。901Please respect copyright.PENANAgP9A0UTPhd

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。901Please respect copyright.PENANAAVg1yI0FZq
901Please respect copyright.PENANAPWeYQJit3W
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。901Please respect copyright.PENANATNOdpFbP1P
