Now, why do you need a cell mediated immune response if you have an antibody response?

为什么你还要有细胞免疫反应呢,你已经有抗体应答了啊

It could be that that signal is 'you need more glucose', and so the cellular response is to create more glucose transporters to bring more glucose into the cell.

这信号还可能是,"需要更多葡萄糖",细胞的反馈就是,产生更多的葡萄糖载体,将更多的糖分子输送进细胞

It could be the response is 'there's something dangerous in the environment, we got to move away', and so the response is for the cell to crawl in the opposite direction.

这个信号还有可能是,"外面很危险,我们得赶紧跑",于是细胞就向相反方向游走了

The immune response is directed at killing this cell.

免疫反应直接杀死了那个细胞

It's the way, for example, that foreign molecules or antigens get presented to cells of your immune system in order to start the process of making an immune response, so sometimes a cell/cell interaction.

通过这种方式,外源分子,或者说抗原,进入到免疫系统的细胞中后,就会开启免疫反应过程,有时候就是细胞之间的相互作用
