'''B cells''' are small white blood cells that help the body defend itself against infection.  These cells are produced in [[bone marrow]]and develop into plasma cells which produce [[antibodies]].

'''B cells''' are white blood cells that help the body defend itself against infection.  These cells are produced in [[bone marrow]]and develop into plasma cells that produce [[antibodies]]. A B cell produces a range of antibodies that are displayed on its cell surface. When the cell takes up a pathogen or foreign antigens by [[endocytosis]], these select which antibody the cell will produce and stimulate it to secrete these [[proteins]] into the blood. This process is called "B cell activation".
