Then, your muscle cells would start producing Hepatitis B surface antigen and your immune system recognizing that's a foreign protein would start responding to it.
于是,肌肉细胞将会,开始制造乙肝表面抗原,然后免疫系统就会识别出,那是外来蛋白质并且产生免疫应答
-
These are cells that recognize a particular antigen, they're ready to differentiate into antibody.
这些记忆细胞可识别相应的抗原,它们已经准备好分化产生抗体
-
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
-
How do they recognize it?
抗体是怎样识别抗原的呢
-
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
-
Another subset of T-cells called T helper cells will recognize that signal by direct contact with it, and they will become activated and proliferate.
另外一个T细胞的亚群是辅助性T细胞,辅助性T细胞可识别与其接触的抗原信号,并被激活,开始增殖
-
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
-
Because it has MHC-1, your MHC-1 on it, this T-cell recognizes that it's one of your cells but it has a foreign antigen associated with it.
因为该细胞上有MHC-1,T细胞将这些细胞识别为自身细胞,但这些细胞带有异己抗原
-
They're capable of recognizing MHC1 together with foreign antigens.
它们能够同时识别MHC1和外源抗原
-
Immune cells recognize it, and they recognize it by a very special form of receptor-ligand interaction where the ligand is MHC1 with the foreign antigen and the receptor is a receptor called the T-cell receptor complex.
免疫细胞识别出染病细胞,通过一种特殊形式的,受体配体协作机制识别出来,其中的配体是同,外源抗原共同出现的MHC1,而这其中受体是T细胞受体复合体
