| immune-response gene | <molecular biology> Any of several genes of the major histocompatibility complex that control the immune response of lymphocytes to specific antigens. (09 Oct 1997) |
|---|---|
| immune response genes | Gene's in the HLA-D region of the histocompatibility complex of human chromosome 6 which control the immune response to specific antigens. (05 Mar 2000) |
| immune sera | Serum that contains antibodies. It is obtained from an animal that has been immunised either by antigen injection or infection with microorganisms containing the antigen. (12 Dec 1998) |
| immune suppression | Suppression of the immune response by some compound or agent. (05 Mar 2000) |
| immune surveillance | <immunology> The hypothesis that lymphocyte traffic ensures that all or nearly all parts of the vertebrate body are surveyed by visiting lymphocytes in order to detect any altered self material, for example mutant cells. (18 Nov 1997) |
| immune system | <immunology> The body system, made up of many organs and cells, that defends the body against infection, disease and foreign substances. The immune system is often stimulated in specific ways to fight cancer cells. (16 Dec 1997) |
| immune thrombocytopenia | Thrombocytopenia associated with antiplatelet antibodies. See: isoimmune neonatal thrombocytopenia, autoimmune neonatal thrombocytopenia. (05 Mar 2000) |
| immune thrombocytopenic purpura | <haematology> A low number of platelets in the blood, which is common in people with HIV, but often resolves as immune deficiency worsens. HIV-related ITP usually does not have serious consequences. Its cause has not been definitely determined. Treatment with AZT frequently alleviates the condition. (09 Oct 1997) |
| immune tolerance | The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (foetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc. (12 Dec 1998) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| anticomplementary serum | Serum that destroys or inactivates complement. (05 Mar 2000) |
| antiepithelial serum | An antiserum (cytotoxin) for epithelial cells. (05 Mar 2000) |
| anti-kidney serum nephritis | Experimental glomerulonephritis produced by injection of antiserum to kidney. (05 Mar 2000) |
| antilymphocyte serum | Immunoglobulins raised xenogeneically against lymphocyte populations. Referring particularly to antisera recognising one or more antigenic determinants on T-cell populations. Of use in experimental immunosuppression. (18 Nov 1997) |
| antirabies serum | A sterile solution containing antibodies obtained from the blood serum or plasma of a healthy animal, or human, that has been immunised against rabies by means of vaccine; administered immediately after severe or multiple bites by domestic animals suspected to be rabid and in all wild animal bites, to be followed by a regimen of rabies vaccine.
