| immune complex nephritis | An immune complex disease resulting from glomerular deposits, as in systemic lupus erythematosus. (05 Mar 2000) |
|---|---|
| immune deficiency | Impaired ability of the bodys defence mechanisms to combat infections by bacteria, viruses and fungi. (13 Nov 1997) |
| immune deficiency diseases | Those diseases in which immune reactions are suppressed or reduced. Reasons may include congenital absence of B and/or T lymphocytes or viral killing of helper lymphocytes (see HIV). (18 Nov 1997) |
| immune deviation | Modification of an immune response to an antigen after prior exposure to that antigen. Synonym: split tolerance. (05 Mar 2000) |
| immune electron microscopy | Electron microscopy of biological specimens to which specific antibody has been bound. (05 Mar 2000) |
| immune haemolysin | A sensitizing, complement-fixing, haemolytic antibody formed in an animal as the result of parenteral administration of red blood cells or whole blood from another species; immune haemolysin may also be formed in human beings who are transfused with human blood that is antigenic in the recipient, e.g., the formation of anti-Rh antibody in an Rh-negative person who is treated with Rh-positive red blood cells. (05 Mar 2000) |
| immune haemolysis | Haemolysis caused by complement when erythrocytes have been sensitised by specific complement-fixing antibody. Synonym: conditioned haemolysis. (05 Mar 2000) |
| immune inflammation | See: allergic reaction. (05 Mar 2000) |
| immune interferon | <cytokine> Interferon elaborated by T lymphocytes in response to either specific antigen or mitogenic stimulation. This type II interferon can be produced by recombinant DNA technology and is similar to the interferon secreted by lymphocytes and has antiviral and antineoplastic activity. Synonym: antigen interferon, immune interferon. Pharmacological action: antineoplastic agent, antiviral agents. (20 Sep 2002) |
| immune opsonin | specific opsonin |
| immune paralysis | The induction of tolerance in mice due to injection of large amounts of polysaccharide. The polysaccharide is poorly metabolised and the paralysis remains only during the persistence of the above. (05 Mar 2000) |
| immune precipitation | <immunology> The precipitation of a multivalent antigen by a bivalent antibody, resulting in the formation of a large complex. The antibody and antigen must be soluble. Precipitation usually occurs when there is near equivalence between antibody and antigen concentrations. (18 Nov 1997) |
| immune protein | An immunoglobulin molecule that has a specific amino acid sequence by virtue of which it interacts only with the antigen that induced its synthesis in cells of the lymphoid series (especially plasma cells) or with antigen closely related to it. Antibodies are classified according to their ode of action as agglutinins, bacteriolysins, haemolysins, opsonins, precipitins, etc. (18 Nov 1997) |
| immune reaction | Antigen-antibody reaction indicating a certain degree of resistance, usually in reference to the 36-to 48-hour reaction in vaccination against smallpox; because the degree of resistance indicated by the reaction is not true immunity and may disappear relatively rapidly there is a tendency to refer to the immune reaction as an allergic reaction. (05 Mar 2000) |
| immune response | <immunology> Alteration in the reactivity of an organisms immune system in response to an antigen, in vertebrates, this may involve antibody production, induction of cell-mediated immunity, complement activation or development of immunological tolerance. (18 Nov 1997) |
