9/21/2009 2 An immune response is characterized by the production of proteins (called immunoglobulins or antibodies) and specifically reactive lymphocytes (T cells) when a host encounters a foreign macromolecules or cell. The inducing substances are called antigens , i.e., anti body gen erators), or immunogens. Immunogenicity is the inherent ability of a substance to induce a specific immune response: Immunogen + B cells ± Effector B cells (Plasma cells) + Memory B cell Immunogen + T cells ± Effector T cells (Helper T Cell/Cytotoxic T Cell) + Memory B cell Antigenicity is the ability to combine specifically with the final products of the above responses, i.e., antibodies and/or cell-surface receptors.
