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。787Please respect copyright.ＰＥＮＡＮＡkBw7JKOsAB

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。787Please respect copyright.ＰＥＮＡＮＡldlW8Xvn2t

（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。787Please respect copyright.ＰＥＮＡＮＡb0r20fLS75

只不過，若癌細胞沒有表達PDL1蛋白質的話，此方法便不奏效。787Please respect copyright.ＰＥＮＡＮＡ1FB7mvLNOw
787Please respect copyright.ＰＥＮＡＮＡCbJNN8gZ2i
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。787Please respect copyright.ＰＥＮＡＮＡHPwRiKwXQC

（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。787Please respect copyright.ＰＥＮＡＮＡPZDjfZoSYO

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。787Please respect copyright.ＰＥＮＡＮＡ24aD2JwZ5L
787Please respect copyright.ＰＥＮＡＮＡbkBnn5ZO3Q
（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。787Please respect copyright.ＰＥＮＡＮＡTG7TuUKgP3

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。787Please respect copyright.ＰＥＮＡＮＡMNuFb2iQ5N
