The other part of the adaptive immune system is the cell mediated immune system and this is an immune where that doesn't involve antibodies but involves cells that are activated in response to a foreign antigen and that utilize cellular means to get rid of it.

获得性免疫系统还包括,细胞免疫,这一免疫反应不包含抗体,但包含可以被激活来应答,并清除外源抗原的免疫细胞

What I want you to remember is that specific sub-populations of cells get activated, the activation results in a specific response.

我希望你们记住的是,一些特定的细胞亚群受到刺激时,被激活细胞将引起特定的应答

You can put somebody in an MRI machine now and have them read a book and look at what parts of their brain become activated when they're reading and what parts stop activating when they stop reading, so you can learn where in their brain is reading done.

现在如果有人躺在核磁共振仪中进行阅读,我们就可以看到,在阅读时,大脑哪些部位变得活跃,停止阅读时哪些部位停止活动,这样我们就知道了,大脑中什么部位是和阅读相关的

In the same way cells get activated but these are different cells, these are T helper cells that get activated by MHC2.

以相同方法另一些不同的细胞也被激活,它们是被MHC2激活的T附助细胞

So, when the right signal is received, the right T-cell finds your host cell with a foreign virus in it, the first thing that happens is that this T-cell becomes activated and it starts reproducing, making more copies of itself.

所以 当接收到正确的信号,恰当的T细胞寻觅到,感染外源病毒的细胞时,首先发生的是,T细胞被激活并开始增殖,制造更多自身拷贝
