They're ready to rapidly differentiate into antibody producing cells and they're waiting for that second signal to come.

并可以迅速分化为,抗体分泌细胞,记忆细胞在等待第二次信号的到来

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

They both proliferate, increase in number, and they differentiate; they differentiate from immature B-cells into antibody producing cells.

淋巴细胞将迅速增殖,数量大幅提高,同时发生分化,幼B淋巴细胞分化,形成能够分泌抗体的细胞

耶鲁公开课 - 生物医学工程探索课程节选

Helper cells don't become cytotoxic cells but they help B cells become antigen producing - antibody producing cells.

附助细胞不会成为细胞毒细胞,它们帮助B细胞成为抗体分泌细胞

耶鲁公开课 - 生物医学工程探索课程节选

So not all of the B-cells that are stimulated become plasma cells or antibody secreting cells.

所以,并不是所有的B淋巴细胞,被刺激分化成为,浆细胞或是抗体分泌细胞

耶鲁公开课 - 生物医学工程探索课程节选

In the case of the helper cells they stimulate a specific population of B-cells to mature into antibody producing cells, and that antibody is generated against the antigen that stimulated it.

以辅助性T细胞为例,辅助性T细胞刺激特定的B细胞,使这些细胞成长为抗体分泌细胞,抗体分泌细胞产生大量的抗体,以消灭大量增殖的抗原
