    The thymus gland plays an important role in the development of a normal, healthy immune system. In particular it is involved in the selection of the lymphocytes (a subset of white blood cells) that will go on to help defend us against infection while protecting us from lymphocytes that could potentially attack our own organs (autoimmune disease).

    The thymus gland is located in the neck above the heart. The function of the thymus gland is to generate mature T lymphocytes (white blood cels that help the immune system fight off illness). Damage to the thymus gland can cause an increase in infection.
