腸道發炎的時候,腸道會製造一些游離基(Reactive oxygen species)用來消滅外來的入侵者。316Please respect copyright.PENANAFVVL14NNHc
較為常見的游離基就是H2O2 ,亦即是俗稱為雙氧水的化學物。316Please respect copyright.PENANAGziv2u4QWy

當細菌接受過多的游離基侵襲,便會死去。316Please respect copyright.PENANAhbblD8qTEZ

(圖2)奈何道高一呎,魔高一丈,有一些細菌內含化解雙氧水的蛋白酶,更把雙氧水化解而成的氧氣供自己所用,不但不受損傷,反而加快自己的生長速度。316Please respect copyright.PENANASzGJe4436u

(圖3)腸道發炎產生的游離基,腸道一隻名為NOX1的蛋白質有份參與製作的過程。316Please respect copyright.PENANAiFWhHl36Rg

316Please respect copyright.PENANAhvS1AUnQ1E
當NOX1蛋白質在老鼠身上除去後,腸道發炎其間,那些擁有化解雙氧水及運用氧氣特性的細菌亦再也沒能快速滋長,奠定了腸道發炎時產生的游離基對個別細菌類別的影響。316Please respect copyright.PENANAHC713Eg6k0
