| 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) |
|---|---|
| gratuitous inducer | <molecular biology> A gratuitous inducer is a molecule which is structurally similar to another molecule that induces transcription for a specific product, and which can also initiate transcription for that product when the official inducer is absent. (09 Oct 1997) |
| inducer | <molecular biology> An extracellular molecule that enters a cell and initiates transcriptionof a gene or operon. (09 Oct 1997) |
| inducer cell | <cell biology> Cells that induce other nearby cells to differentiate in specified pathways. Perhaps the distinction should be made, as of old, between those cells that evoke a predetermined pathway of differentiation in the target cells and those cells that can actually induce new and unexpected differentiations. (18 Nov 1997) |
| 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) |
| helper cell | A subset of T lymphocytes that acts in cooperation with B lymphocytes to permit antibody formation. Synonym: inducer cell. (05 Mar 2000) |
| helper factor | A group of factors apparently produced by helper T lymphocytes that act specifically or non-specifically to transfer T-cell help to other classes of lymphocytes. The existence of specific T-cell helper factor is uncertain. (18 Nov 1997) |
| helper phage | A virus which helps a separate and unrelated defective virus reproduce by infecting the same host cell that is already occupied by the defective virus and providing the proteins which the defective virus is missing and needs to complete its life cycle. (09 Oct 1997) |
| helper t lymphocyte | <haematology, immunology> A type of white blood cell produced by the thymus gland whose presence is necessary for normal levels of antibodies to be produced by B lymphocytes, both in the body (in vivo) and in experimental situations (in vitro). (09 Oct 1997) |
| helper virus | <virology> A virus that will allow the replication of a co-infecting defective virus by producing the necessary protein. (18 Nov 1997) |
| helper viruses | Viruses which enable defective viruses to replicate or to form a protein coat by complementing the missing gene function of the defective (satellite) virus. Helper and satellite may be of the same or different genus. (12 Dec 1998) |
| t4 helper lymphocyte | A specific type of lymphocyte, derived from the thymus gland, that plays an important role in cellular immunity. T4 lymphocytes (CD4 cells) are decreased (absolute counts less than 200) in patients with AIDS resulting in compromised immune function. (27 Sep 1997) |
| T helper cell | <haematology, immunology> Sets of T lymphocytes that specifically are involved in the differentiation of B lymphocytes into antibody secreting cells. Loss of T helper cells, as in HIV infection, leads to immunosuppression. There is also T-cell help of T-cell function. TH1 and TH2 are now recognised, TH1 helping with cellular, TH2 with humoural immunity. (16 Dec 1997) |
| t-helper cell | Immune cells that are triggered by antibodies to seek and attack invading organisms. Cells called macrophanges summon t-helper cells to the site of the infection and present a protruding antigen onto which the t-helper cell locks, thus recognizing the invading substance. The t4-helper cell then reproduces and secretes its potent lymphokine hormones that stimulate B-cell production of antibodies; signal natural killer or cytotoxic (cell-killing) T-cells; and summon more macrophanges to the site of the infection. T-helper cells are also called t4 cells and are normally twice as common as t8 cells. If a person has aids, the proportion of t4 to t8 cells is often reversed. (12 Dec 1998) |
| T helper cells | A subset of lymphocytes that secrete various cytokines that regulate the immune response. (05 Mar 2000) |
