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 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.
Development
After leaving the bone marrow, the B cell acts as an antigen presenting cell (AP-C) and internalizes offending antigens, which are taken up by the B cell through receptor-mediated endocytosis and processed. Pieces of the antigen (which are now known as antigenic peptides) are loaded onto MHC II molecules, and presented on its extracellular surface to CD4+ T cells (sometimes called T helper cells). These T cells bind to the MHC II-antigen molecule and cause activation of the B cell.
