| globoid cell | A large cell of mesodermal origin that is found clustered in the intracranial tissues in globoid cell leukodystrophy. (05 Mar 2000) |
|---|---|
| globoid cell leukodystrophy | <radiology> Dysmyelinating disease, autosomal recessive, usually presents by 1 yr, specific enzyme deficiency identified, rapid spontaneous nystagmus, poikilothermia Synonym: Krabbe leukodystrophy (12 Dec 1998) |
| CD4 cell | T helper cells which are targets for HIV infection. (09 Oct 1997) |
| CD4 cell count | The most commonly used surrogate marker for assessing the state of the immune system. As CD4 cell count declines, the risk of developing opportunistic infections increases. The normal range for CD4 cell counts is 500 to 1500 per cubic millimetre of blood. CD4 count should be rechecked at least every six to twelve months if CD4s are greater than 500/mm3. If the count is lower, testing every three months is advised. (09 Oct 1997) |
| virus-transformed cell | A cell that has been genetically changed to a tumour cell, the change being subsequently tramsmitted to all descendent cell's; cell's transformed by oncornaviruses continue to produce virus in high concentration without being killed; DNA tumour virus-transformed cell's develop (along with other changes) tumour-associated antigens and rarely produce virus. (05 Mar 2000) |
| CD8 cell | <immunology> One type of T-lymphocyte which bears the CD8 molecular marker on its surface. Some CD8 cells recognise and kill cancerous cells and those infected by intracellular pathogens (some bacteria, viruses and mycoplasma). These cells are called cytotoxic T-lymphocytes (see). (09 Oct 1997) |
| glomerulosa cell | A cell of the zona glomerulosa of the adrenal cortex that is the source of aldosterone; the cell's are arranged in spherical or oval groups. (05 Mar 2000) |
| cell | <cell biology> An autonomous self replicating unit (in principle) that may constitute an organism (in the case of unicellular organisms) or be a sub unit of multicellular organisms in which individual cells may be more or less specialised differentiated) for particular functions. The individual units from which tissues of the body are formed. All living organisms are composed of one or more cells. (26 Mar 1998) |
| cell aggregation | The phenomenon by which dissociated cells intermixed in vitro tend to group themselves with cells of their own type. (12 Dec 1998) |
| cell aging | The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences cell death via the process of apoptosis. (12 Dec 1998) |
| cell behaviour | <cell biology> General term for activities of whole cells such as movement, adhesion and proliferation, by analogy with animal behaviour. (18 Nov 1997) |
| cell biology | <study> The study of the internal workings of cells at the microscopic and molecular level - it is closely linked to molecular biology. (16 Dec 1997) |
| cell body | Used in reference to neurons, the main part of the cell around the nucleus excluding long processes such as axons and dendrites. (18 Nov 1997) |
| cell-bound antibody | A term used for antibody on the surface of cells that may be bound either through antigen combining sites or other sites such as the Fc region. (05 Mar 2000) |
| renal cell cancer | Cancer that develops in the lining of the renal tubules, which filter the blood and produce urine. Also called renal cell carcinoma. (12 Dec 1998) |
