Plasma cell, short-lived antibody-producing cell derived from a type of leukocyte (white blood cell) called a B cell. B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph, these antibody molecules bind to the target antigen (foreign substance) and initiate its neutralization or destruction.
Plasma cell leukemia (PCL) is an aggressive form of multiple myeloma characterized by high levels of abnormal plasma cells circulating in the peripheral (circulating) blood. Normal plasma cells in the bone marrow produce antibodies that fight infection. In myeloma most of the abnormal plasma cells remain in the bone marrow and are not found in the peripheral blood. In PCL, the abnormal plasma cells are in the peripheral blood. Therefore, PCL is considered to be an advanced form of myeloma.
