B cells, or B lymphocytes, are a type of white blood cell. They are involved in so-called humoral immunity, in which the body uses antibodies to fight off infectious agents. Each B cell has receptors on its surface that recognize antigens, which are proteins, polysaccharides, or other macromolecules that the immune system considers foreign (or “non-self”).
