| cytotoxic drugs | <pharmacology> Anti-cancer drugs which act by killing or preventing the division of cells. See: chemotherapy. (13 Nov 1997) |
|---|---|
| cytotoxic reaction | An immunologic (allergic) reaction in which noncytotropic IgG or IgM antibody combines with specific antigen on cell surfaces; the resulting complex initiates the activation of complement which causes cell lysis or other damage, or which, in the absence of complement, may lead to phagocytosis or may enhance T lymphocyte involvement. (05 Mar 2000) |
| cytotoxic T-cell | <haematology, immunology> Subset of T lymphocytes (mostly CD8) responsible for lysing target cells and for killing virus infected cells (in the context of Class I histocompatibility antigens). (18 Nov 1997) |
| cytotoxic t-lymphocyte | A type of CD8 or, less often, CD4 lymphocyte that kills diseased cells infected by a specific virus or other intracellular microbe. CTLs interact with MHC class I receptors (see Major Histocompatibility Complex). On infected cells and have the prime role in cellmediated immunity (see). Cytovene: See: Ganciclovir. (09 Oct 1997) |
| T cytotoxic cells | Lymphocyte-like effector cells which mediate antibody-dependent cell cytotoxicity. They kill antibody-coated target cells which they bind with their fc receptors. (12 Dec 1998) |
| T-lymphocytes, cytotoxic | Immunised T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (mlc), in vivo during a graft-versus-host (gvh) reaction, or after immunization with an allograft, tumour cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (cml). These cells are distinct from natural killer cells (killer cells, natural) and from killer cells mediating antibody-dependent cell cytotoxicity. (12 Dec 1998) |

| serine | <amino acid> Is synthesised by the body from the amino acids glycine or threonine. Its production requires adequate amounts of B-7 (niacin), B-6 and folic acid. It is needed for the metabolism of fats and fatty acids, muscle growth and a healthy immune system. It aides in the production of immunoglobulins and antibodies. It is a constituent of brain proteins and nerve coverings. It is important in the formation of cell membranes, involved in the metabolism of purines and pyrimidines and muscle synthesis. It is also used in cosmetics as a skin moisturizer. Serine is abundant in meats and dairy products, wheat gluten, peanuts and soy products, all of which are common allergens. There is some concern that elevated serine levels can cause immune suppression and psychological symptoms as in cerebral allergies. (22 May 1997) |
