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。719Please respect copyright.ＰＥＮＡＮＡGl9eYJR5E8

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。719Please respect copyright.ＰＥＮＡＮＡBdQUVxQyQp

（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。719Please respect copyright.ＰＥＮＡＮＡVORdQAFiYw

只不過，若癌細胞沒有表達PDL1蛋白質的話，此方法便不奏效。719Please respect copyright.ＰＥＮＡＮＡUHBCEthH4Z
719Please respect copyright.ＰＥＮＡＮＡ3Lzdf8ustx
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。719Please respect copyright.ＰＥＮＡＮＡu8QdfNi3m5

（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。719Please respect copyright.ＰＥＮＡＮＡq6PCTvJGOI

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。719Please respect copyright.ＰＥＮＡＮＡjaSFtlWHdF
719Please respect copyright.ＰＥＮＡＮＡJFbTtbfp7l
（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。719Please respect copyright.ＰＥＮＡＮＡg5cRj9MdMa

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。719Please respect copyright.ＰＥＮＡＮＡyk78NGw20s
