So, I have a bacteria infection, stimulates my immune system, I start making antibodies that bind to an antigen specific to that bacteria.
所以 如果我被细菌感染了,我的免疫系统被激活,开始制造抗体,这些抗体结合到细菌特异性的抗原上
Now, just--what this diagram also shows you is that that response is specific to that particular antigen.
看,就像这幅图表展示的一样,免疫应答是针对特定的抗原
Again, these are antibodies that are specific to that antigen or vaccine that we introduced.
我再说一次,这些抗体针对于,我们所接种的抗原或疫苗特异产生
The antibodies they make are all specific to the antigen that stimulated them.
它们制造的抗体,对激活它们的抗原来说都是特异性的
I realize that this thinking about antigen, antibody combinations and the mathematics of how strongly an antibody binds to a specific antigen, is maybe something that's new to you.
我觉得这些关于 抗原抗体结合,以及,抗体如何强有力地结合抗原的问题,对你们来说很新鲜
What's variable about them is that they bind to a specific antigen.
它们可变的原因是,它们需要结合不同的抗原
In this case here, you're generating host cells, cytotoxic T-cells, that can kill only very specific cells, cells that are expressing this foreign antigen.
而在这个例子中,人产生宿主细胞,即细胞毒性T细胞,它只会消灭特定的细胞,也就是携带特定异己抗原的细胞
The antibody that they stimulate is antibody that's specific to this antigen that was presented earlier.
这些由辅助性T细胞,刺激增殖产生的抗体是,对应之前出现的抗原而产生的
They come from B-cells, they come from B-cells that are activated with a specific antigen.
抗体来自于B细胞,它们来自于被特别的抗原所激活的B细胞
The antibodies that are produced from these B-cells are also specific for the antigen.
产生自B细胞的抗体,对抗原来说是特异性的
