T cells (T lymphocytes) are specialised white blood cells that are critical to a healthy immune system. People who lack T cells also tend to have weak antibody defences, and this is called combined immunodeficiency. These disorders are very rare and hereditary. Examples of Combined Immune Deficiencies are:
X-Linked Severe Combined Immunodeficiency (SCID)
