IMMUNOLOGY

Detailed explanation-1: -Cell-mediated immunity or cellular immunity is an immune response that does not involve antibodies. Rather, cell-mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Detailed explanation-2: -There are two broad classes of such responses-antibody responses and cell-mediated immune responses, and they are carried out by different classes of lymphocytes, called B cells and T cells, respectively.

Detailed explanation-3: -CD8+ T cells, also known as killer T cells (or cytotoxic T cells), are effector cells for cell-mediated immunity. CD4+ T cells, also known as helper T cells, are effector cells for cell-mediated immunity. More items
