T cells are a type of blood cell that protect the body from infection.
All T cells originate from haematopoietic stem cells (a type of adult stem cell) located in the bone marrow. There are certain sub-populations of T cells (that include a number of the CD+ cells). See more about adult stem cells below.
The thymus is a specialized organ of the immune system and contributes fewer cells as a person ages. This is because the thymus shrinks by about 3% a year throughout middle age, resulting in a corresponding fall in the thymic production of naive T cells.
A study published this week on May 15th 2013, by “Immunity & Ageing”, shows slower immune system aging in women than men.
The study (ref: doi: 10.1186/1742- 4933-10-19) concluded:
“the rate of increase of these immunological parameters was greater in women than in men (p < 0.05). T cell proliferation index (TCPI) was calculated from the T cell proliferative activity and the number of T cells. It showed an age-related decline that was greater in men than in women (p < 0.05). The rate of decline in IL-6 and IL-10 production was also greater in men than in women (p < 0.05). “
Age-related changes in various immunological parameters differ between men and woman. Our findings indicate that the slower rate of decline in these immunological parameters in women than that in men is consistent with the fact that women live longer than do men.
Recent research on adult stem cells has generated a great deal of excitement. Scientists now have technologies available to stimulate and replace these adult stem cells using a variety of stem cell therapies. Powerful adult stem cell supplements, such as Stem Cell Worx Intraoral Spray are also available. Stem Cell Worx Intraoral Spray has been scientifically proven to be one of the most powerful stem cell supplements on the market. Its pure, natural ingredients provide a triple effect of stem cell production from the bone marrow, enabling adult stem cells and their subsets CD+ cells, T cell and IL-6 proliferation to increase by as much as 50% within two weeks of taking the Stem Cell Worx Intraoral Spray supplement.
What are Adult Stem Cells?
The history of research on adult stem cells began more than 50 years ago. In the 1950s, researchers discovered that the bone marrow contains at least two kinds of stem cells. One population of adult stem cells is called haematopoietic stem cells, that form all the types of blood cells in the body. A second population, called bone marrow stromal stem cells (also called mesenchymal stem cells, or skeletal stem cells by some), were discovered a few years later. With the latest advancements in the scientific and medical fields, especially in the last 5 years, its now possible to activate these adult stem cells through medical and specialized health supplement means.
An adult stem cell is an undifferentiated cell. This means that under the right direction, adult stem cells can transform into a specific type of cell that promotes tissue, muscle, cartridge and organ repair and renewal.
