What is a T-cell?
A T-cell is a type of white blood cell called a lymphocyte. It helps the immune system fight germs and protects the body from disease.
There are 2 forms, namely:
- Cytotoxic T-cell destroys infected cells;
- Helper T-cell sends a signal to other immune cells and calls them to fight infection.
A T-cell is formed in the bone marrow, matures in the thymus, and travels to the lymph tissue or bloodstream.
The thymus is much larger in childhood and shrinks with age. Statistically, the thymus produces much fewer T-cells when a person is 20 years old. As for the supply, it already depends on the body's ability, that is, how much it can copy and multiply the already existing T-cells.
T-cell function is affected by autoimmune diseases and immunodeficiency disorders.
