| T-lymphocytes | Lymphoid cells concerned with cell-mediated immunity. They originate from lymphoid stem cells that migrate from the bone marrow to the thymus and differentiate under the influence of the thymic hormones. Various subpopulations have been described. (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) |
| T-lymphocytes, helper-inducer | Subpopulation of CD4+ lymphocytes that cooperate with other lymphocytes (either t or b) to initiate a variety of immune functions. For example, helper-inducer T-cells cooperate with B-cells to produce antibodies to thymus-dependent antigens and with other subpopulations of T-cells to initiate a variety of cell-mediated immune functions. (12 Dec 1998) |
| T-lymphocytes, suppressor-effector | Subpopulation of CD8+ T-lymphocytes which suppress antibody production or inhibit cellular immune responses. Suppressor-effector cells execute the message received from suppressor-inducer cells (T-lymphocytes, suppressor-inducer). (12 Dec 1998) |
| 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) |
