Growth & Immune Factors
Growth factors help with such vital functions as the normal growth of tissue, and help repair aged or injured muscle, skin collagen, bone, cartilage and nerve tissues. These factors also stimulate the body to build lean muscle, and burn fat for fuel when dieting.
IFG-1, IGF-II, FgF, and GH (growth hormone) have been shown to help stimulate cell and tissue growth by stimulating DNA formation. Genetically engineered versions of IGF-1 and GH are now marketed as anti-aging and AIDS drugs. They are found naturally and in high concentrations in colostrum. Several studies show that these growth factors are capable of increasing T-cell production, accelerating healing, balancing blood glucose, reducing the need for insulin, increasing muscle and bone growth, and repairing while metabolizing fat for fuel.
Epithelial Growth Factor (EGF) is instrumental in protecting and maintaining the skin. Along with the other growth factors in colostrum, EGF can stimulate normal skin growth and repair cellular tissue.
Immunoglobulins, also known as antibodies, are substances produced by the body’s immune system in response to bacteria, viruses, or other foreign substances, such as fungus, animal dander, or cancer cells. Antibodies attach to the foreign substances, causing them to be destroyed by other immune system cells.
The five major types of antibodies are:
IgA antibodies are found mainly in areas of the body such the nose, breathing passages, digestive tract, ears, eyes, and vagina. IgA antibodies protect body surfaces that are exposed to the outside from foreign organisms and substances. This type of antibody is also found in saliva and tears. About 10% to 15% of the antibodies usually present in the body are IgA antibodies. A small percentage of people do not make IgA antibodies.
IgG antibodies are found in all body fluids. They are the smallest but most abundant of the antibodies, normally comprising about 75% to 80% of all the antibodies in the body. IgG antibodies are considered the most important antibodies for fighting bacterial and viral infections. IgG antibodies are the only type of antibody that can cross the placenta. Therefore, the IgG antibodies of a pregnant woman can also help protect her baby.
IgM antibodies are the largest type of antibody. They are found in blood and lymph fluid and are the first type of antibody produced in response to an infection. They also cause other immune system cells to produce compounds that can destroy invading cells. IgM antibodies normally comprise about 5% to 10% of all the antibodies in the body.
IgD antibodies are found in small amounts in the tissues that line the abdominal or chest cavity of the body. The function of IgD antibodies is not well-understood. They appear to play a role in allergic reactions to some substances such as milk, some medications, and some poisons.
IgE antibodies are found in the lungs, skin, and mucous membranes. They cause the body to react against foreign substances such as pollen, fungus spores, and animal dander. IgE antibody levels are often high in people with allergies.
