Usually the cellular means that they get rid of is that instead of an antibody being produced, you activate a population of cells that will specifically go and hunt down the foreign antigen, or more commonly, cells that contain the foreign antigen.

通常细胞免疫意味着,不用生成抗体就能清除抗原,你激活了一个细胞类群,这一类群能够,并杀伤外源抗原,或者更常见的是,杀伤含有外源抗原的细胞

If that protein is an enzyme then you've and you've switched it from an 'off' position where it's not catalyzing a reaction to an 'on' position where it is, you've changed the biochemical state of the cell, you've changed the chemical reactions that can occur within the cell, and you've changed its behavior.

如果这种蛋白是一种酶的话,你就能够将酶从无催化作用的静息态,激活至能催化反应的激活态,你改变了细胞的生化状态,也改变了细胞内发生的化学反应,改变了细胞的行为
