<P> Plasma cells , also called plasma B cells , plasmocytes , plasmacytes , or effector B cells , are white blood cells that secrete large volumes of antibodies . They are transported by the blood plasma and the lymphatic system . Plasma cells originate in the bone marrow ; B cells differentiate into plasma cells that produce antibody molecules closely modelled 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 . </P>
