T cells are a very important type of white blood cell as they play a central role in the adaptive immune response and can be distinguished from other white blood cells by the presence of a T cell receptor (TCR) on their surface.
Born from hematopoietic stem cells, T cells originate in the bone marrow, then migrate to the thymus gland to develop. After migration, the naive cells mature into several distinct types of T cells. Each group of T cell subtypes have a variety of important functions in controlling and shaping the immune response.
In order to mature, a specific protein, created in the thymus gland, must bind to the T cell receptor. This protein, discovered by Dr. Beardsley, is known as Thymic Protein A.
As with humans, a dog's thymus begins to atrophy as it ages, producing less and less of this essential protein. Twell, with Thymic Protein A, helps fill this gap; picking up where the thymus left off and providing the necessary TPA to help keep your dog's T cells at their optimal levels.
Thymic Protein A and its effects on the immune system have been researched, studied and written about for decades. Below are several samples of those works.
