Quizplus · Accepted Answer

A memory cell is a previously stimulated (sensitized) antibody-producing cell that rapidly releases antibodies when the body is reexposed to its inciting antigen. Antigenic memory provides organisms with immunity against pathogens to which they have been previously exposed. An autoreactive lymphocyte destroys the body's own tissues (e.g., in autoimmune diseases like rheumatoid arthritis or systemic lupus erythematosis). A natural killer cell is a lymphocyte that can kill foreign cells without a history of previous antigen exposure. An activated lymphocyte is a lymphocyte with a previous history of exposure to an antigen.
