T cell Function
While in the thymus gland, T cells multiply and are capable of combining with specific foreign antigens which makes them ‘sensitized’ to that specific Antigen. These cells then produce a specific immunity to that particular Antigen. This is called Cell Mediated Immunity.
There are several types of T cells within the body, each with specific, unique functions. The destruction of foreign cells directly is accomplished by Natural Killer T cells (NK cells), Helper T cells release substances which stimulate or regulate other T cells in the destruction of foreign invaders. It is these Helper T Cells that are destroyed by the AIDS virus, making it so dangerous.
Specific T cells, called Suppressor T cells, turn off the immune response when it is no longer necessary. In order to retain the memory of a specific Antigen, Memory T cells keep a chemical picture of the foreign substance so that the Immune System can respond rapidly the next time this same invader is encountered.
In putting this all together, T cells work together with Macrophages, which devour the invaders, in the immune process. In order for a T cell to respond and build a resistance, the Antigen must be ‘presented’ to the T cell on the surface of a Macrophage.
B Cells and Antibodies
The chemical substance the body uses to destroy a specific invading Antigen is called an Antibody. Also known as an Immunoglobulin (Ig), Antibodies are manufactured by the second type of Lymphocyte, the B cells, present in the Immune System. Each of these cells in turn, produces Antibodies, chemicals that circulate in the blood, destroying the Antigen. This form of immunity is called Humoral Immunity because ‘humoral’ refers to the body fluids. Like the T cells, some of the B cells remain active in the blood and retain the memory of the specific Antigens they have battled in the past. Should these substances enter the body again; these cells will be able to respond to the invasion much more rapidly than before.
While we understand that this brief description of the Immune System may seem complex, keep in mind that from infancy forward, your Immune System is capable of protecting you from many millions of foreign substances, even those that are synthetic or manmade. All through this process, the system is kept in check so that it does not overreact, for should this occur, Allergies or worse yet, Autoimmune Disease may be the result. Due to lack of proper nutrients from the daily diet, combined with the ever increasing number of synthetic foreign chemicals, not found in nature, invading our environment, the Immune System can become exhausted. If this occurs it does not always recognize some of these Antigens, allowing them to multiply within us to the point of infectious or chemically induced disease. I talk more about this in my special report Your Immune System -Why It Fails & How to Fix It.
As you can see by my series of articles on the Immune System it is a complex and delicate system indeed. The health of your immune system is translates to your overall health so what’s the best way to keep it healthy?
1. Get adequate rest
2. Get regular exercise
3. Take a Full Spectrum nutrient supplement every day
4. Use an immune boosting/nourishing supplement to keep your immune system strong
The combination of formulas we recommend are called High Vitality Multiple and ImmuGuard – a targeted support formula for the immune system. Both of these are available from Phoenix Nutritionals or by calling them at 1-800-440-2390.
