What is cell-mediated inflammation?
Cell-mediated 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.
What is the meaning of cell-mediated immunity?
Cell mediated immunity (CMI) is that arm of the immune response that does not involve antibodies but rather incorporates the activation of macrophages and NK cells enabling them to destroy intracellular pathogens, the production of antigen-specific CD8 cytotoxic T-lymphocytes (CTLs), and the release of various …
Why is it called cell-mediated?
cell-mediated immunity, so named because the T cells themselves latch onto the antigens of the invader and then initiate reactions that lead to the destruction of the nonself matter.

What is an example of cell-mediated immunity?
Examples of Cell-Mediated Immunity A tiny amount of protein, extracted from the bacteria, is injected into the skin. If the subject is currently infected, or has ever been infected, with the bacteria, a positive test results. In 24 hours or so, a hard, red nodule develops at the site of the injection.
