  1. B cell

    B cells belong to a group of white blood cells known as lymphocytes, making them a vital part of the immune system -- specifically the humoral immunity branch of the adaptive immune system. B cells can be distinguished from other lymphocytes, such as T cells and natural killer cells, by the presence of a protein on the B cell's outer surface known as a B cell receptor. This specialized receptor protein allows a B cell to bind to a specific antigen. The principal functions of B cells are to make antibodies against antigens, to perform the role of antigen-presenting cells, and to develop into memory B cells after activation by antigen interaction. Recently, a new, suppressive function of B cells has been discovered. The abbreviation "B", in B cell, comes from the bursa of Fabricius in birds, where they mature. In mammals, immature B cells are formed in the bone marrow, which is used as a backronym for the cells' name, despite the fallacious etymology.
