What is the immune system? The immune system, which is made up of special cells, proteins, tissues, and organs, defends people against germs and microorganisms every day. In most cases, the immune system does a great job of keeping people healthy and preventing infections.

When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that’s left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

Each day you inhale thousands of germs (bacteria and viruses) that are floating in the air. Your immune system deals with all of them without a problem. Occasionally a germ gets past the immune system and you catch a cold, get the flu or worse. A cold or flu is a visible sign that your immune system failed to stop the germ. The fact that you get over the cold or flu is a visible sign that your immune system was able to eliminate the invader after learning about it. If your immune system did nothing, you would never get over a cold or anything else.

There are also all kinds of human ailments that are caused by the immune system working in unexpected or incorrect ways that cause problems. For example, some people have allergies. Allergies are really just the immune system overreacting to certain stimuli that other people don’t react to at all. Some people have diabetes, which is caused by the immune system inappropriately attacking cells in the pancreas and destroying them. Some people have rheumatoid arthritis, which is caused by the immune system acting inappropriately in the joints. In many different diseases, the cause is actually an immune system error.

Finally, we sometimes see the immune system because it prevents us from doing things that would be otherwise beneficial. For example, organ transplants are much harder than they should be because the immune system often rejects the transplanted organ.

The health of your immune system impacts every other system in your body. Where your immune system is located and organs of immune system:

Immune System organs
1. Bone Marrow – All the cells of the immune system are initially derived from the bone marrow. They form through a process called hematopoiesis. During hematopoiesis, bone marrow-derived stem cells differentiate into either mature cells of the immune system or into precursors of cells that migrate out of the bone marrow to continue their maturation elsewhere. The bone marrow produces B cells, natural killer cells, granulocytes and immature thymocytes, in addition to red blood cells and platelets.

2. Thymus – The function of the thymus is to produce mature T cells. Immature thymocytes, also known as prothymocytes, leave the bone marrow and migrate into the thymus. Through a remarkable maturation process sometimes referred to as thymic education, T cells that are beneficial to the immune system are spared, while those T cells that might evoke a detrimental autoimmune response are eliminated. The mature T cells are then released into the bloodstream.

3. Spleen – The spleen is an immunologic filter of the blood. It is made up of B cells, T cells, macrophages, dendritic cells, natural killer cells and red blood cells. In addition to capturing foreign materials (antigens) from the blood that passes through the spleen, migratory macrophages and dendritic cells bring antigens to the spleen via the bloodstream. An immune response is initiated when the macrophage or dendritic cells present the antigen to the appropriate B or T cells. This organ can be thought of as an immunological conference center. In the spleen, B cells become activated and produce large amounts of antibody. Also, old red blood cells are destroyed in the spleen.

4. Lymph Nodes – The lymph nodes function as an immunologic filter for the bodily fluid known as lymph. Lymph nodes are found throughout the body. Composed mostly of T cells, B cells, dendritic cells and macrophages, the nodes drain fluid from most of our tissues. Antigens are filtered out of the lymph in the lymph node before returning the lymph to the circulation.

5. Antibodies – Identify and neutralize foreign objects like bacteria and viruses. Each antibody recognizes a specific antigen unique to its target.

6. White blood cells – Varying types of white blood cells (including T-Cells) help to defend the body against infections disease and foreign materials.

Questions and Answers (back)

How does my immune system work? (back)

The immune systems classifies what is part of the body and what is not, identifies one invader from another, switches on search and destroy teams against invaders, switches off when danger passes, and remembers the enemies of the past.

How do the parts of my immune system communicate? (back)

A special protein called interferon (a class of Cytokines) carries messages between cells and tissues. When a cell is infected with a virus, the cell releases interferons. Interferons alert other healthy cells to shield itself from this virus and request enzymes that destroy them. The killer enzyme is called T Cells or killer T Cells. Macrophages or white blood cells clean up the mess after the battle is over. Nutriferon is a supplement that helps your cells produce interferons to keep your immune system running optimally.

Why does your immune system not attack its own cells? (back)

Markers of Self: At the heart of the immune response is the ability to distinguish between "self" and "non-self." Every cell in your body carries the same set of distinctive surface proteins that distinguish you as "self." Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers; rather, your immune system coexists peaceably with your other body cells in a state known as self-tolerance. This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I proteins, which are on all cells, and MHC Class II proteins, which are only on certain specialized cells.

Markers of Non-Self: Any non-self substance capable of triggering an immune response is known as an antigen. An antigen can be a whole non-self cell, a bacterium, a virus, an MHC marker protein or even a portion of a protein from a foreign organism. The distinctive markers on antigens that trigger an immune response are called epitopes. When tissues or cells from another individual enter your body carrying such antigenic non-self epitopes, your immune cells react. This explains why transplanted tissues may be rejected as foreign and why antibodies will bind to them.

NOTE: transfer factors s contain inducers and suppressors that help balance the immune system’s response to disease. The inducers are used by the "brain" transfer factors s to activate more "combat" cells into battle against germs and disease when needed ...without turning against your body.

Which natural supplements for immune system can be used? (back)

transfer factors - an extract from the colostrum (first mother's milk). Every newborn (humans and animals) drink colostrum the first 3 days of their lives. This is a natural booster for immune system by over 437% and a strong, healthy immune system can cure ANYTHING, and also can protect from getting sick. A growing number of holistic doctors are using transfer factors in their practices to modulate the immune system and for health conditions. Read more
Vitamin C - important antioxidant that decreases susceptibility to infection.
Omega 3 Fatty Acids - a necessary element in our diet for a healthy immune system.
Garlic - is a natural antibiotic, anti-inflammatory, anti-viral, and anti-bacterial.

What are immune system disorders? (back)

1. Immunodeficiency - when the immune system does not recognize invaders as being undesirable and therefore does not mobilize to destroy them.
2. Autoimmunity (self-destruction) - when the immune system fails to recognize 'self' as friendly and mounts an attack on itself." Explaining Autoimmune Disease by David Isenberg, PhD and John Morrow, PhD

Duane Townsend, MD: " transfer factors and transfer factors Formula helps to modulate the immune system." (autoimmunity - over-active immune system)

Baruch Rosen MD: " transfer factors Formual Plus, a preparation which enhances and stimulates the body's own immune system to fight against all pathogens, viral or otherwise." (Immunodeficiency - underactive immune system)

What are the causes for a poor immune system? (back)

Over weight, alcoholism, poor nutrition and illegal drug abuse are common causes of poor immune function.

Which Foods Best Boost Your Immune System? (back)

transfer factors - boosts immune system by over 437%.
