Infections trigger the immune system to recognize and respond to foreign antigens, as memory cells persist after an infection to identify these specific antigens [1], [2]. Furthermore, the immune system utilizes antibodies to target antigens to clear an infection [3], while lymphoid tissues trap antigens from infection sites to initiate adaptive responses [4].

claimWhen B-cells encounter foreign material (antigens), they respond by maturing into plasma cells or memory cells, the latter of which allow a rapid response if the same infection is encountered again.
