Cellular immunity is a protective immune process that involves the activation of phagocytes, antigen-sensitized cytotoxic T cells and the release of cytokines and chemokines in response to antigen. Cellular immunity is most effective against cells infected with viruses, intracellular bacteria, fungi and protozoans, and cancerous cells.
2. cell-mediated immunity (def): Cell-mediated immunity involves the production of cytotoxic T-lymphocytes, activated macrophages, activated NK cells, and cytokines in response to an antigen (def) and is mediated by T-lymphocytes.We will now take a look at the steps involved in adaptive immune responses.D. An Overview of the Steps Involved in the Adaptive Immune Responses. Whether humoral immunity (def) or cell-mediated immunity (def), there are several general steps involved in the immune responses.e will now take a look at the steps involved in adaptive immune responses.
