| cytotoxicity, immunologic | The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitised T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement. (12 Dec 1998) |
|---|---|
| cytotoxicity tests, immunologic | The demonstration of the cytotoxic effect on a target cell of a lymphocyte, a mediator released by a sensitised lymphocyte, an antibody, or complement. (12 Dec 1998) |
| suppressor factors, immunologic | Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-j) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory. (12 Dec 1998) |
| desensitization, immunologic | Immunosuppression by the administration of increasing doses of antigen. Though the exact mechanism is not clear, the therapy results in an increase in serum levels of allergen-specific IgG, suppression of specific IgE, and an increase in suppressor T-cell activity. (12 Dec 1998) |
| dose-response relationship, immunologic | A specific immune response elicited by a specific dose of an immunologically active substance or cell in an organism, tissue, or cell. (12 Dec 1998) |
| immunologic | <immunology> Pertaining to immunology. (18 Nov 1997) |
| immunologic and biological factors | A collective grouping for biologically active substances that play a role in the functioning of the immune system and those that show biological or physiological activity. (12 Dec 1998) |
| immunologic capping | The process by which lymphoid cell surface immunoglobulin receptors, when exposed to bivalent anti-ig antibodies, collect in patches and form a cap at one pole of the cell. The caps may then be endocytosed or shed into the environment in the form of antigen-antibody complexes. Capping has also been induced by lectins and antigens. (12 Dec 1998) |
| immunologic deficiency syndromes | Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral. (12 Dec 1998) |
| immunologic diseases | Disorders caused by abnormal or absent immunologic mechanisms, whether humoral, cell-mediated or both. (12 Dec 1998) |
| immunologic factors | Biologically active substances whose activities affect or play a role in the functioning of the immune system. (12 Dec 1998) |
| immunologic high dose tolerance | Induction of tolerance by exposure to large amounts of protein antigens. (05 Mar 2000) |
| immunologic memory | <immunology> The ability to rapidly produce large quantities of specific immune cells after subsequent exposure to a previously encountered antigen. (09 Oct 1997) |
| immunologic pregnancy test | A general term for test's for detection of increased human chorionic gonadotropin in plasma or urine by immunologic techniques including latex particle agglutination, haemagglutination inhibition, radioimmunoassay, and radioreceptor assays. (05 Mar 2000) |
| immunologic surveillance | The theory that T-cells monitor cell surfaces and detect structural changes in the plasma membrane and/or surface antigens of virally or neoplastically transformed cells. (12 Dec 1998) |
