They're just antigens that belong to you and so you don't normally mount an immune response to antigens that are part of you.

它们是你的自身抗原,但通常对自身抗原不会产生免疫反应

One of the things that happens is that certain cells within your body process the vaccine or the antigen and we talked about that.

在人体内,发生的反应之一是,特定的细胞对疫苗或者抗原做出反应,之前我们讨论过这个

耶鲁公开课 - 生物医学工程探索课程节选

So, antigens are molecules or pieces of molecules that stimulate an immune response.

所以 抗原是可以激发免疫反应的,分子或分子碎片

耶鲁公开课 - 生物医学工程探索课程节选

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

耶鲁公开课 - 生物医学工程探索课程节选

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

If there were just-- if you were trying to create a positive reaction of antigens and it showed up naturally wouldn't it create this reaction anyway in terms of your body would create antibodies like the secondary response volume to antibodies?

如果这里仅有,如果在自然条件下,尝试建立抗原的阳性反应,抗体这是否会像这样反应,以你身体为例,你的身体是否会产生,同二次免疫一样的抗体浓度

耶鲁公开课 - 生物医学工程探索课程节选

When these CD8 T-cells see your MHC1 together with an antigen that doesn't belong in you, it creates an immune response.

当CD8 T细胞识别MHC1时,同时识别了不属于你的抗原,由此产生免疫反应

耶鲁公开课 - 生物医学工程探索课程节选

Because this antigen gets expressed in the context of MHC2, your immune system responds differently.

因为这些抗原同MHC2共同表达,所以你的免疫反应就会不同
