T cellWith the B cell, one of the two main types of white blood cell, essential parts of the immune system. T cells originate in the bone marrow, mature in the thymus, and travel in the blood to other lymphoid tissues, such as the spleen, tonsils, and lymph nodes. Through receptor molecules on their surfaces, T cells directly attack invaders (antigens) by binding to them and helping remove them from the body. Because the body contains millions of T and B cells, many of which carry unique receptors, it can respond to virtually any antigen. See also antibody, immunology. How to thank TFD for its existence?

| Sander Van Deventer, allows the modulation of T-lymphocytes, such that the cells express the anti-inflammatory protein IL-10. Recently, oversecretion of interleukin-18 by monocytes in patients with HLH has been described (50); interleukin-18 production may further enhance TNF-[Alpha] and IFN-[Gamma] production by T-lymphocytes and NK cells, as well as induce Fas ligand expression on lymphocytes, which enhances their cytotoxic effect. AIDS researchers know that such T-lymphocytes are the primary target of the AIDS-causing human immunodeficiencyvirus (HIV). |
