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.
Cancer cells that are coated in monoclonal antibodies may be more easily detected and targeted for destruction. Triggering cell-membrane destruction. Some monoclonal antibodies can trigger an immune system response that can destroy the outer wall (membrane) of a cancer cell. Blocking cell growth. Some monoclonal antibodies block the connection between a cancer cell and proteins that promote cell growth â an activity that is necessary for tumor growth and survival.
