这种病毒的变化就是因为我们所说的抗原漂移或是抗原更换。
The virus is really changing because of what we call antigenic drift and shift.
疫苗灌装和发放:将每批疫苗稀释以得到所需的抗原浓度,然后装瓶或灌入注射器,并加贴标签。
Vaccine filling and release: the batch of vaccine is diluted to give the desired concentration of antigen, and put into vials or syringes, and labeled. A number of these are then tested.
但当抑制性T细胞想要阻止这一行为时,他们被传递了相同的抗原,开始杀死抗原呈递细胞。
But when the weak t cells that want to stop the disease are presented with those same antigens, they kill the APC.
They just wait, they wait for their time, they wait until you are in danger from a particular antigen.
它们时刻准备着,在等待着那一刻,等待你被某种特别的抗原威胁的时刻
We looked at the kinetics of this response, what happens in your body after you're exposed to an antigen.
我们曾学习过这种应答的效应,当人体遇到抗原后会发生怎样的变化
So, now you have a single molecule, very large molecule, with not just two binding sites but with ten binding sites.
所以如果你体内有一个细胞,一个体积很大的细胞,细胞表面不只有两个抗原结合位点,而有十个抗原结合位点
