Immune System Support
An optimally functioning immune system is essential for the body to address any disease including cancer- The following is an overview of specialized immune cells and components:
- Natural Killer (NK) cells are described as the "sentinel" cell in the immune system, because in healthy
individuals they are the first cells to encounter cancer cells, invading bacteria and virally infected cells. They can take on and kill multiple disease cells simultaneously and also have a regulatory effect on the rest of the immune system.
- Macrophages are the "Pac-men" of the immune system. They engulf disease cells, digest them and display fragments of the digested invader which become "antigens" that stimulate the appropriate B cell and T cell proliferation.
- Lymphocyte is a type of white blood cell that is long lived and carries memory of past infections. As they
mature they eventually turn into B and T cells.
- T cells are a class of lymphocytes (also called T lymphocytes) derived from the thymus that control cell
mediated immune reactions and the development of B cells. There are three fundamentally different types
of T cells: helper, killer and suppressor. Each has many subdivisions.
- B cells are a type of lymphocyte normally involved in the production of antibodies to combat infection. During infections, individual B cell clones multiply and are transformed into plasma cells, which produce large amounts of antibodies against particular antigen on a foreign microbe.
- Interleukin-12 is released by macrophages in response to infection and begins the process of
customizing immune system cells to suit the specific invader. It enhances the ability of Natural Killer (NK) cells to destroy microbes and cancer cells, induces interferon production and stimulates the production of activated T cells and NK cells.
- Interleukin-2 is a chemical messenger, a substance that can improve the body's response to disease. It stimulates the growth of certain disease-fighting blood cells in the immune system.
- Tumor Necrosis Factor (TNF) is released by macrophages and induces fever. It kills cancer cells and caused the production of lymphokines.
- Interferon refers to a family of glycoproteins derived from human cells which normally has a role in fighting viral infections by preventing multiplication in cells.
