Regulatory T cells and B cells: implication on autoimmune diseases
... B cells usually need the help provided by T cells to get activated upon encountering antigens to differentiate into effector plasma cells. Plasma cells produce or secrete antibodies that subsequently circulate in the blood, lymph, and tissues where they can target specific antigens or pathogens and ...
