cyto-inhibition
| hapten inhibition of precipitation | Inhibition of precipitation that occurs when the precipitin has combined with hapten of the same specificity as the subsequently added antigen. (05 Mar 2000) |
|---|---|
| conjugated hapten | A hapten that may cause the production of antibodies when it has been covalently linked to protein. Synonym: conjugated antigen. (05 Mar 2000) |
| half-hapten | A substance that elicits an antigen-antibody reaction, but no precipitation. (05 Mar 2000) |
| hapten | <immunology, molecular biology> Could be considered an isolated epitope: although a hapten (by definition) has an antibody directed against it, the hapten alone will not induce an immune response if injected into an animal, it must be conjugated to a carrier (usually a protein). The hapten constitutes a single antigenic determinant, perhaps the best known example is dinitro phenol (DNP) that can be conjugated to BSA and against which antiDNP antibodies are produced (antibodies to the BSA can be adsorbed out). Because the hapten is monovalent, immune complex formation will be blocked if the soluble hapten is present as well as the hapten carrier conjugate (assuming there is more than one hapten per carrier then an immune precipitate can be formed). Competitive inhibition by the soluble small molecule is sometimes referred to as haptenic inhibition and this term has carried over into lectin mediated haemagglutination where monosaccharides are added to try to block haemagglutination: the blocking sugar defines the specificity of the lectin.

| Forssman hapten | A glycolipid from mammalian organs. Compare: Forssman antibody, Forssman antigen. (05 Mar 2000) |
| allogeneic inhibition | Inhibition or injury to allogeneic cells that occurs when lymphocytes are mixed and cultured with other cells of different genotypes in vitro. (05 Mar 2000) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
| reactive inhibition | Tendency toward a lessened strength of response due to practice or activity. It is independent of the effect of reward and is a direct function of time interval since the last response and the number of preceding responses. (12 Dec 1998) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reflex inhibition | A situation in which sensory stimuli decrease reflex activity. (05 Mar 2000) |
| cell migration inhibition | Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated leukocytes or macrophages. Specific assays have been developed to estimate levels of migration-inhibitory factor, immune reactivity against tumour-associated antigens, and immunosuppressive effects of infectious microorganisms. (12 Dec 1998) |
| central inhibition | <physiology> Suppression or diminution of outgoing impulses from a reflex centre. (05 Mar 2000) |
| residual inhibition | The inhibition or suppression of tinnitus by use of a sound-generating device (residual inhibitor) which masks the sounds of tinnitus and produces a residual sound-inhibiting effect when the device is turned off. (05 Mar 2000) |
| retroactive inhibition | The partial or complete obliteration of memory by a more recent event, particularly new learning. Compare: proactive inhibition. (05 Mar 2000) |
