immmune-competent cells derived from the thymus
Cells of the immune system that originate in the thymus gland. They are found in the blood, lymph, and lymphoid organs.
White blood cells that are produced in the bone marrow but mature in the thymus. They are important in the body's defences against certain bacteria and fungi, help B lymphocytes make antibodies, and help in the recognition and rejection of foreign tissues. T lymphocytes may also be important in the body's defence against cancers.
Specialized lymphocytes that mature within the thymus; two important types are Cytotoxic T cells and helper T cells.
( T Cells): are produced in the bone marrow to interact with body cells to regulate the immune response.
type of white blood cell specialised in certain immune reactions. There are several types of T lymphocytes (T3, T4, T8 lymphocytes, suppressor lymphocytes...), each fulfilling specific needs. T lymphocytes do not secrete antibodies.
a type of white blood cell specializing in the body's defense against viruses and the rejection of foreign tissues.
