Dr. Atmika Paudel, PhD says... The facts about thymus gland written in the article below are medically correct.

Thymic Protein A is a patented product for the thymus gland that can help restore thymus function and boost immune system function. On this page you are going to learn about how the thymus gland functions and why it’s so important for treating yeast infections. Remember, yeast infections are largely an illness of the immune system and they signal an imbalance in immune health. This is a for warning that you are becoming a candidate for cancer since the same white blood cells are involved in defending the body from fungi as are involved in the defense of cancer.

How Does The Thymus Gland Work

White blood cells are the defenders of the body and come in various different forms. You have a few kinds of T-cells and B-cells. T-cells have various types known as T-4 helper cells, T-8 killer cells, and T-8 suppressor cells. T-4 cells are helper cells that work by activating other immune cells to produce antibodies by the B-cells. T-8 killer cells are directed by the T-4 helper cells to attack and destroy cancer, viruses, and fungal cells. T-8 suppressor cells signal to the T-8 killer cells to end the attack when the invader is eradicated.


All these cells are known as lymphocytes and attack viruses, bacteria, and fungi. These cells are produced from stem cells in the bone marrow and the B-cells leave the bone marrow fully mature and are then sent into the body to recognize foreign invaders and produce antigens. T-cells on the other hand leave the bone marrow and have to travel to the thymus gland to be activated as the other T-cell types.

The thymus gland is a small organ that lies beneath the breastbone and by puberty is fully mature and weighs about 10 ounces. Shortly after your 20th birthday the thymus gland begins to shrink as the thymic cells begin to die off to be replaced by fat and connective tissue. This slow die-off of the thymus gland lowers immune system function as you can possibly imagine. This is also a known biomarker of aging.

A number of animal extracts and synthetic hormones have been found to reverse thymic atrophy and restore levels of immunity to that of younger years. They have also been documented to extend the life of animals in laboratory tests. Most thymic products on the market however, are made from biologically inactive thymus tissues, cell debris, fragments of thymus proteins, and thymus by-products that make them ineffective.

Thymic Protein A and The Thymus Gland

Terry Beardsley, Ph.D., is an immunologist and experimental biologist from Baylor College of Medicine in Texas. He has been the principal scientist in the Monoclonal Antibody Facility at Smith Kline Beckman; Assistant Professor of research at the University of California at San Diego; Research Associate at Scripps Clinic, La Jolla; and Assistant Research Professor at UCLA’s Laboratory of Nuclear Medicine

He has spent most of his career researching the thymus gland and in 1980 established the first growing line of growing thymic stromal cells. Although these cells did increase immune system function he was not satisfied with the results. 8 years later he discovered a 500-amino protein chain that fit into the T-4 receptor cells that turned on the programming and disease fighting ability of these cells. Remember the T-4's activate the other T-cells. He then developed a unique oral delivery system that avoided destruction in the stomach, which is a significant problem with other thymic supplements.

Because of this extensive research and clinical studies, Dr. Beardsley was awarded a US patent in 1997 for Thymic Protein A and its method of production.

Thymic protein A has been proven to be totally safe and has been proven to make a huge difference in increased immune function against infections and pathogenic agents.

Dr. Julian Whitaker says that Thymic Protein A is quite possibly the strongest natural stimulator of immune system function ever discovered. He recommends one to three packets a day to be taken when ill and also recommends a maintenance dose be taken daily for support.

This is a great product for restoring immune function to beat yeast infections. You may want to seriously consider it.

Medical Review by Dr. Atmika Paudel, PhD

The entire article is written about a product for immune boosting. I am not endorsing the product, however, I would like to mention here about the importance of thymus gland in immunity. 

In human and all vertebrate animals, immunity is of two types: innate immunity and adaptive immunity. If we link these immunities with thymus glans, we can say that the innate immunity is thymus gland independent while adaptive immunity is thymus gland dependent.

As mentioned in the article above, the adaptive immune system has T lymphocytes and B lymphocytes. These lymphocytes can recognize specific antigen and are able to remember them. T lymphocytes travel from bone marrow to thymus for maturation and differentiation, as mentioned in the article above. Defect in thymus gland is associated with several disorders such as autoimmune diseases where T-cells can not differentiate between foreign from self-tissue and acts against the body.

Thymus gland is largest and most active during the early stages of life such as neonatal and pre-adolescent periods, as this is the age where new antigens are recognized and the memory is kept in the body. As we age, the thymus begins to decrease in size and activity. Therefore, ways to regenerate thymus gland and modulate thymic output can boost the production of T cells and promote T-cell reconstitution after treatments that severely depletes T cells, such as in bone marrow transplantation and chemotherapy and after severe viral infections.
