Detailed explanation-1: -cell-mediated immunity. Antibody-mediated immunity is the branch of the acquired immune system that is mediated by B-cell-antibody production. The antibody-production pathway begins when the B cell’s antigen-binding receptor recognizes and binds to antigen in its native form.
Detailed explanation-2: -Acquired immunity includes both humoral immunity, as well as cell-mediated immunity.
Detailed explanation-3: -The humoral immune response is mediated by antibody molecules that are secreted by plasma cells.
Detailed explanation-4: -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.
Detailed explanation-5: -Helper T cells, killer T cells, and macrophages are the three main kinds of lymphocytes involved in cell-mediated immunity. When a “helper” T cell encounters an antigen-presenting cell in the body, it releases cytokines, which are signaling proteins.
