Memory cells are long lasting cells that remember this exposure and can respond very quickly on second exposure.

记忆细胞可以长时间记忆与抗原的接触,并在再次免疫中迅速做出应答

If we just thought about that second part of it, just the antibody generation, or the humoral what we called last time--last week, the humoral immune response, the immune response associated with humoral immune response of antibodies in the blood and in other fluids.

当我们仅考虑上述过程的第二步,也就是产生抗体的部分,或是我们上周学习的,体液免疫应答,这种免疫应答与,血液中以及其他体液中的抗体有关

One of the things that I didn't mention before is that when you get this primary response and then the secondary response, if you looked at the antibodies that are generated during the primary response, again we're only looking at antibodies that bind to the particular antigen or vaccine that we have used for the priming.

还有一点我之前没有提及,当你获得初次免疫,以及再次免疫之后,如果你仔细观察抗体,观察那些在初次免疫中生成的抗体,这次我们同样只是观察抗体,那些与我们在初次免疫中所用到的,特定抗原或疫苗相结合的抗体

For example, HIV enters cells of the immune system by binding to a receptor called CD4.

比如,HIV通过与CD4的受体结合,进入到免疫系统细胞中
