T Cells are produced in the thymus gland which works flat out for the first few years
of life and then rapidly shuts down. Our lifetime supply of T cells diminishes with age
and the process can be accelerated by stress and disease. After they go, so do we.
In this photo the T Cells (coloured white) are attacking a defective body cell. T Cells
are an essential part of our immune system and their depletion in old age increases the
risk of cancer.
Please be patient while the photo of the T Cells downloads. It is certainly worth the
wait. |
