It can separate between what's part of yourself and what's foreign, and it does that by presenting, by recognizing antigens that are presented in the context of the major histocompatibility complex, MHC.

免疫系统可以识别出哪些是属于你的,哪些是外来的,它通过呈递和识别抗原达到目的,而抗原是存在于,主要组织相容性复合体中的

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

So, our bodies are capable of making antibodies that are tuned for all the potential antigens that we come into contact with, That's amazing that we have this capacity to respond and you respond only when needed.

所以 我们的身体具有制造抗体的能力,这些抗体对于各种潜在抗原具有特异性,我们具有只在需要时做出,免疫反应的能力 这太让人惊叹了

We're going to talk about this kind of non-covalent interaction more when we talk about the immune system, because one example of ligand and receptors that's important in the immune system are antigens - foreign molecules, and antibodies - molecules that we produce.

当我们讲到免疫系统的时候,会更详细地谈到这种非共价化合反应,因为在免疫系统中,一个重要的配体受体结合反应,就是抗原,即外源分子,与抗体,这个人体自身产生的分子结合

So, these memory cells are a way that your immune system keeps track of antigens that it's been exposed to for even if maybe the plasma cells that were producing antibody in response to the initial exposure have died and disappeared.

所以,这些记忆细胞,是人体免疫系统记忆抗原的一种方法,即使由浆细胞产生的抗体,在初次免疫应答中全部被消灭,记忆细胞仍然能迅速分化为抗体分泌细胞
