The cell-mediated immunity differs from humoral immunity in that they respond differently to invaders. The cell mediated immunity is a type of immune response that dose not involve antibodies, however it involves the activation of phagocytes, antigen specific cytotoxic T-lymphocytes, and the release of various cytokines in response to a foreign body (antigen). The humoral immune response is mediated by antibody molecules that are secreted by plasma cells.
