The cells that are activated in the adaptive immune response undergo clonal expansion which means that they massively proliferate.

在适应性免疫中被激活过的细胞会进行克隆扩增，意味着它们会大量增殖。

Either way, if the antigen is the right " fit" for the T cell, it will begin to differentiate and undergo clonal expansion.

无论哪种方式，如果抗原“适合”T细胞，那T细胞将开始分化并进行克隆扩增。
