WebThe B-cell proliferates, resulting in short-lived plasma cells producing IgM, but also undergoes somatic hypermutation for identification of the optimal antigen-binding B-cell receptor (BCR)–expressing clone. WebMemory B cells that differentiate into plasma cells output tens to hundreds-fold greater antibody amounts than were secreted during the primary response ( Figure 17.18 ). This rapid and dramatic antibody response may stop the infection before it can even become established, and the individual may not realize they had been exposed.
