癌細胞有各種手段逃避我們身體免疫系統的追捕,其中之一的手段就是在表面上表達名為PDL1的蛋白質。637Please respect copyright.PENANA9ZGVpmcdBY

免疫系統細胞表面的PD1蛋白質與PDL1確認的話,便不會追殺癌細胞,任由惡勢力增長。637Please respect copyright.PENANAGTlofSCQxD

(圖2)用抗體阻擋PD1,導致免疫系統細胞不再受癌細胞蒙騙,繼而懂得消滅癌細胞,就是免疫治療的精髓所在。637Please respect copyright.PENANAIzLsmB6s1u

只不過,若癌細胞沒有表達PDL1蛋白質的話,此方法便不奏效。637Please respect copyright.PENANA3E5mSwsoX1
637Please respect copyright.PENANATqyHT8ouPk
而且就算癌細胞真的是有表達PDL1蛋白質,此方法對某一些病人亦不太見效。637Please respect copyright.PENANAA29PWDhajA

(圖3)有研究發現,腸道的細菌群組能夠影響免疫治療的效果。637Please respect copyright.PENANAcEy6YEnVcx

因此,有臨床研究嘗試將對免疫治療有效的病人的腸道細菌,以手術及口服糞便藥丸的方法移植到對免疫治療無效的病人腸道,試驗能否增強免疫治療的效用。637Please respect copyright.PENANAGErss3RY3h
637Please respect copyright.PENANAbSV1D5ZhA4
(圖4)利用糞便移植手段,原先對免疫治療無效的病人亦出現顯著的效果。637Please respect copyright.PENANAN0b8nyEx02

是次研究共有五名試驗者,有三名出現了正面效果。其中一名病患在半個月後,身上的皮膚癌更是完全消失。637Please respect copyright.PENANA5AkvipbXQl
