What are stimulated B cells called? What do they secrete?

Activated B cells differentiate into plasma cells, which are the antibody-secreting factories of the immune response. Plasma cells produce and release large quantities of antibodies specific for the encountered antigen, circulating to bind and neutralize pathogens or mark them for attack by other immune cells. Some B cells become memory B cells for quicker responses upon re-exposure, but they don’t secrete antibodies immediately. Plasma cells aren’t the main source of cytokines, and B cells don’t secrete antigens themselves—the antibodies are what target the antigens.
