初次免疫应答(the initial response)
抗原特异性免疫记忆是免疫的基本特征,其物质基础是初次免疫应答后产生的抗原特异性的记忆性T淋巴细胞和记忆性B淋巴细胞以及浆细胞。
Antigen-specific immunological memory is a cardinal feature of immunity, which depends on generation and maintenance of memory t lymphocytes, B lymphocytes and plasma cells with antigen specificity.
结论抗hbv特异性主动免疫对初次免疫无应答者的再次免疫有一定的疗效。
Conclusion Anti-HBV specific active immunotherapy shows a certain efficacy for non-responders immunized with standard hepatitis B vaccine.
如图所示,实验动物对初次免疫和二次免疫的应答有明显的不同。
An animal will show different responses for a primary response and a secondary response as shown in the figure.
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
