Activated B cells proliferate, ultimately producing plasma cells, which secrete antibody, and long-lived memory cells. Affinity maturation and class switching occur in the primary response; these enable a swift and more effective secondary response. T-independent antigens can stimulate an antibody response by activating B cells without the aid of T-helper cells.
