HGH REVIVES AND
REJUVENTATES THE IMMUNE SYSTEM

(return to top)
HGH and the immune system are very interconnected. A healthy immune system is very important in protection against cancer, autoimmune diseases, and infectious diseases. In fact as age increases the immune system becomes increasingly weak and unable to protect against cancer and other diseases. As the rate of cancer rises with age at the same time the amount of growth hormone (GH) decreases. There is an abundance of data that shows from animal and human studies that HGH revives and rejuvenates the immune system.

HGH REGROWS ESSENTIAL
THYMUS GLAND FOR KILLER T CELLS

The main organ of the immune system is the thymus gland which is located behind the top of the breastbone. Around age 12 this gland begins to shrink until by age 40 it is around half its former self and by age 60 it is difficult to find. Through the Thymus gland there is the maturation of the T-cell lymphocytes which are the foot soldiers in the battles against disease. As the thymus shrinks there is a rise in diseases associated with aging including cancer. In fact AIDS involves the loss of T cells which brings the breakdown of defense against all kinds of other diseases which means that in a sense AIDS is an accelerated process of aging.` Also, the shrinking of the Thymus is one of the main bio markers of aging. In 1985 Dr. Kelly, a research immunologist at the University of Illinois at Urbana-Champaign injected old rats whose thymus had almost disappeared with Growth Hormone 3 cells (GH3) which are cells that secret high quantities of growth hormone (GH). The thymus gland in these old rats grew back to the full size and function of young rats. These old rats also produced more interleukin 2 which is synthesized by T cells and goes down in old rats. Also, Israeli scientists have used bovine growth hormone to reverse shrinking in mice and have shown similar results with dogs.

HGH SIGNIFICANTLY IMPROVES
ALL ASPECTS OF IMMUNE SYSTEM

Tests show the Immune activities that the GH improves are higher activity of natural killer (NK) cells that protect against cancer; increased production of T-cells and interleukin 2, manufacture of new anti-bodies, greater proliferation and activity of disease-fighting white blood cells, increased maturation of neutrophils and white blood cells that are very destructive to microorganisms, increased stimulation of bacteria-engulfing macrophages, increased erythropoiesis, and the increased production of new red blood cells.

HGH RESTORES
ESSTENTIAL BONE MARROW STEM CELLS

Even more important than the Thymus is the bone marrow of the long bones that are the birth place of all the very important cells including the T cells that mature in the Thymus gland. In the bone marrow are the stem cells that give rise to T cells and the progenitor cells that function to form and develop into red and white blood cells of the immune system. In more recent HGH research Dr. Kelly found that the bone marrow of rodents and old humans was significantly depleted of progenitor cells which give rise to all these important cells of the immune system. When GH was given to the old rats the progenitor cells came back. It is not known how this happens but is believed that somehow the environment where the stems cells sit is blocked with increasing age and that human growth hormone has a way of overcoming this block. According to Greg Fahy, PH.D., and prominent researcher in cellular physiology at the Naval Medical Research Institute in Bethesda, Maryland, there is now the chance of maintaining an immune system at the age of 80 which is similar to age 20 because of what has been shown in animals and is strongly suggestive in humans. In fact, the improvement of the immune system means that many things that change with age are restored such as normal cell division, normal thyroid hormone levels, normal insulin sensitivity, ability to make DNA, normal populations of molecules in the brain that change with age and so on.
