| cytosolic | Relating to or contained in the cytosol. (05 Mar 2000) |
|---|---|
| cytosome | <cell biology> A specialised region of various protozoans in which phagocytosis is likely to occur. Often there is a clear concentration of microtubules or/and microfilaments in the region of the cytostome. In ciliates there may be a specialised arrangement of cilia around the cytostome. (18 Nov 1997) |
| cytostasis | The slowing of movement and accumulation of blood cells, especially polymorphonuclear leukocytes, in the capillaries, as in a region of inflammation; obstruction of a capillary as the result of accumulated leukocytes. Origin: cyto-+ G. Stasis, standing (05 Mar 2000) |
| cytostatic | <pharmacology> An agent that suppresses cell growth and multiplication. Origin: Gr. Statikos = bringing to a stand still (18 Nov 1997) |
| cytostome | The cell "mouth" of certain complex protozoa, usually with a short gullet or cytopharynx leading food into the organism, where it is collected into food vacuoles, then circulated inside the body, eventually to be excreted through the cytopyge. Origin: cyto-+ G. Stoma, mouth (05 Mar 2000) |
| cytotactic | Relating to cytotaxis. (05 Mar 2000) |
| cytotactin | <protein> See tenascin. (18 Nov 1997) |
| cytotaxis | The movement of a cell toward or away from some sort of stimulus. (The stimulus would then be called the cytotaxin). (09 Oct 1997) |
| cytothesis | The repair of injury in a cell; the restoration of cells. Origin: cyto-+ G. Thesis, a placing (05 Mar 2000) |
| cytotoxic | <pharmacology> Chemicals that are directly toxic to cells, preventing their reproduction or growth. Cytotoxic agents can, as a side effect, damage healthy, noncancerous tissues or organs which have a high proportion of actively dividing cells, for example, bone marrow, hair follicles. These side effects limit the amount and frequency of drug administration. (16 Dec 1997) |
| cytotoxic cell | Cells of the immune system that inhibit or help to terminate an immune response, e.g., suppressor macrophages and suppressor T-cells. Synonym: cytotoxic cell. (05 Mar 2000) |
| 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 lymphocyte-specific serine protease | <enzyme> Structural sequence given in first source Registry number: EC 3.4.21.- Synonym: cytotoxic t lymphocyte-specific serine protease ccp I, cytotoxic t lymphocyte specific serine protease ccp II, mast cell protease type II (26 Jun 1999) |
| 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) |
