B cell (B lymphocyte)

A type of white blood cell normally involved in the production of antibodies to combat infection. The mature B cell is often called a plasma cell. An antibody ‘sticks’ to an antigen on a foreign cell, causing the antibody-antigen cell to be destroyed or to break down. Tumours of mature B cells result in B cell lymphoma and sometimes myeloma.
