When activated by binding to an antigen, B-cells proliferate into plasma or memory B-cells. Memory B-cells don’t produce antibodies, and instead reside for a long time in the lymphoid tissue, acquiring information about pathogens and storing them away for later. If an infection is caused by that same pathogen in the future, the memory B-cells will coordinate a quicker immune response.

Key Points

  •  Memory B cells
    • Long-lived
    • Store information (memory) about the pathogen after an infection
    • Do not produce antibodies
