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

But this antigen presenting cell is more likely a professional antigen presenting cell, or a subset of cells of your immune system that are specialized in ingesting foreign particles and displaying their contents to the rest of the immune system.

但这种抗原呈递细胞更加类似于,专职抗原呈递细胞,或者是体内免疫细胞中的一个亚群,专门从事吞噬异己物质,并告知免疫系统的其他细胞的工作

And so we talked very briefly last time about this business of antigen presentation, how your immune system-- one of the things that it does especially well, is recognize what's part of you and what's not part of you.

上次我们简单的提到过,有关抗原呈递的一些知识,你的免疫系统如何,这也是免疫系统尤其擅长的一点,就是识别哪些部分属于你,哪些不属于

So, those wrong proteins get presented on MHC1 and your immune system can kill the cell because it's a tumor cell.

所以 当这些错误的蛋白,同MHC1一起被呈递,你的免疫系统就可以消灭这些肿瘤细胞

Now, for antibody production it is still a T-cell that recognizes the antigen presenting cell.

现在,抗体的产生,仍是源于T淋巴细胞识别出抗原呈递细胞

That gets presented in the context of MHC1 on cells within your body.

在体内,病毒同MHC1共同呈递

We talked about host cells that are perhaps infected with a virus, displaying pieces of that virus, antigenic pieces of that virus in the context of a surface receptor called MHC-1, presenting that.

我们说到过,可能受到病毒感染的宿主细胞,表现出病毒的一部分特征,病毒的抗原部分,其表面受体称为主要组织相容性抗原-1,MHC-1负责呈递抗原
