active immunity see acquired i. artificial immunity acquired (active or passive) immunity produced by deliberate exposure to an antigen, as in vaccination. cell-mediated immunity (CMI), cellular immunity acquired immunity in which the role of T lymphocytes is predominant.genetic immunity innate i.mmunity resulting from the development within the body of antibodies or sensitized T lymphocytes that neutralize or destroy the infective agent. This may result from the immune response to an invading organism or from inoculation with a vaccine containing a foreign antigen.
Cell-mediated immunity (CMI) is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK-cells, the production of antigen-specific cytotoxic T-lymphocytes (def), and the release of various cytokines (def) in response to an antigen (def).ytokines that regulate adaptive immunity are produced primarily by T-lymphocytes that have recognized an antigen specific for that cell. These cytokines function in the proliferation and differentiation of B-lymphocytes and T-lymphocytes after antigen recognition and in the activation of effector cells.
