Although they look very similar they are extraordinarily diverse in their functions. The most abundant forms are B and T cells. The B cells are produced and mature in the bone marrow. In comparison the precursors of T cells leave the bone marrow and mature in the Thymus. B and T cells are specific to particular antigens (they are able to recognise and bind to precise molecular structures via receptors). Most of the T cells in the body belong to one of two subsets. These are distinguished by the presence on their surface of one or the other of two glycoproteins designated: * CD4 * CD8 Which of these molecules is present determines what types of cells the T cell can bind to. * CD8+ T cells bind epitopes that are part...
