How do plasma cells form, and how do they help fight pathogens. Answers. Plasma cells, they are also called plasma B cells, 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.
A plasma cell is a type of white blood cell that normally produces antibodies to fight infections. People with multiple myeloma have cancerous plasma cells, also called myeloma cells, which replace normal cells and form tumors in bones and, occasionally, in various soft tissues of the body. Myeloma cells may also prevent the bone marrow from making enough red blood cells, white blood cells, and platelets.
