Absolute CD8 Suppressor Cells
The surface of a cytotoxic T cell has something called a CD8 receptor. The CD8 receptor interacts with cells called major histocompatibility complex Class I molecules, to recognise when healthy cells are infected. When the CD8 receptor recognises an infected cell, it activates the cytotoxic T cells, and the cytotoxic T cells create molecules designed to destroy the infection.
Why it matters: Several types of autoimmune disease affect T cells. Other conditions that affect them include acute lymphocytic leukaemia, a type of cancer that starts in the blood and bone marrow; adult Hodgkin lymphoma, a disease in which cancer cells start in the lymph system; HIV, a virus that attacks white blood cells and potentially leads to AIDS; Job syndrome, a rare immune system disorder that causes repeat infections; and thymic aplasia, a condition in which someone is born with an underdeveloped thymus.
