| T-lymphocytes, suppressor-inducer | Subpopulation of CD4+ lymphocytes which induce CD8+ suppressor T-cells (T-lymphocytes, suppressor-effector) to suppress antibody production by B-cells. They also stimulate other cellular immune responses. (12 Dec 1998) |

| T suppressor cell | <haematology, immunology> Set of T lymphocytes (usually CD8) specifically involved in suppressing B-cell differentiation into antibody secreting cells. There may also be T suppresors of T-cell functions. (18 Nov 1997) |
| t-suppressor cell | A type of immune cells, also called t8 cells, these cells close down the immune response after it has destroyed invading organisms. T8 cells are sensitive to high concentrations of circulating lymphokine hormones and release their own lymphokines after an immune response has achieved its goal, signalling all other participants to cease their attack. Some memory B-cells remain to ward off a repeat attack by the invading organism. (12 Dec 1998) |
| tumour suppressor | <molecular biology, oncology> A gene that encodes a product that normally negatively regulates the cell cycle and that must be mutated or otherwise inactivated before a cell can proceed to rapid division. Examples: p53, RB retinoblastoma), WT 1 (Wilm's tumour), DCC (deleted in colonic carcinoma), NF 1 (neurofibrosarcoma) and APC adenomatous polyposis coli). (18 Nov 1997) |
