His initial response to Sunday's dramatic events was delivered in the form of a written statement.
VOA: standard.2009.04.13
You would have this initial response, now that initial response might be too slow to prevent you from getting chickenpox.
你对水痘病毒产生初始应答,这种初始应答可能,过于缓慢,无法预防水痘
The answer is "Yes you would", the question is "Would that response, even though it's much faster, be fast enough to protect you from the initial exposure to tetanus that you got?"
是的,你的身体会马上做出应答,问题是 即便免疫应答十分迅速,但是否足够迅速,以保护你不被破伤风杆菌感染
So, these memory cells are a way that your immune system keeps track of antigens that it's been exposed to for even if maybe the plasma cells that were producing antibody in response to the initial exposure have died and disappeared.
所以,这些记忆细胞,是人体免疫系统记忆抗原的一种方法,即使由浆细胞产生的抗体,在初次免疫应答中全部被消灭,记忆细胞仍然能迅速分化为抗体分泌细胞
If we did the experiment where on this booster we included not only the initial antigen but some unrelated antigen, the response to the unrelated antigen called B here, looks like a primary response.
如果实验中我们使用的后续疫苗,不仅包括原抗原,还包括一些无关抗原,这里将对无关抗原的应答称为B,该应答就如同初次免疫一样
If you looked later, as the antibody production response matures, some IgG is produced so that in the late period after initial priming you'd have a mixture of IgM and IgG in the blood.
如果你稍后再观察,等到产生抗体的应答趋于成熟后,就会产生一些IgG抗体,在初次免疫的最终阶段,你的血液中有IgM,和IgG两种抗体
