WebApr 9, 2024 · Summary. 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, and the release of various cytokines in response to an antigen. Cell-mediated immunity is directed primarily … WebCytotoxic T lymphocytes (CTL) are major effectors in cell-mediated immune reactions. Once activated they search out and bind to cells that express inappropriate of “foreign” structures on their surfaces and, by a mechanism that remains unclear, program them to die. The CTL then move away to search for a new target, leaving the cell that has ...
