2 .3 克隆选择 每一个体都含有许多淋巴细胞克隆 ,每一克隆由一个前体细胞产生 ,有其独特的抗原受体 ,不同的克隆能识别不同的抗原决定簇并与之发生反应。抗原激活相应的特异性淋巴细胞克隆 ,使其增生和分化成效应与记忆细胞。这个过程称为克隆选择。当记忆细胞再次遇见相同
2.3. Clonal Selection Each individual contains many lymphocyte clones. Each clone is produced by a precursor cell and has its own unique antigen receptor. Different clones recognize and react with different antigenic determinants. The antigen activates the corresponding specific lymphocyte clone, causing it to proliferate and differentiate into effector and memory cells. This process is called clone selection. When memory cells meet again the same
