Question

Quizplus · Accepted Answer

Clones of B or T cells are produced only when their surface receptors recognize a specific antigen. This is known as clonal selection, where a specific antigen binds to its complementary receptor on a lymphocyte and triggers its activation and proliferation into a clone of identical cells with the same antigen specificity. This process ensures that only immune cells with a high affinity for a particular pathogen are activated to mount an effective response, while avoiding activation of irrelevant or self-reactive cells.
