| HLA-b27 antigen | <immunology> Human histocompatibility (HLA) surface antigen encoded by the b locus on chromosome 6. It is strongly associated with acute anterior uveitis, ankylosing spondylitis, and reiter's disease. Increased frequency of antigen in: ankylosing spondylitis (90%), Reiter syndrome (90%), enteropathic arthritis (75%), psoriatic arthritis (60%) normal frequency: white: 8%, black: 4% (12 Dec 1998) |
|---|---|
| HLA-b35 antigen | <immunology> Human histocompatibility (HLA) surface antigen encoded by the b locus on chromosome 6. It is weakly associated with a number of diseases. (12 Dec 1998) |
| HLA-b7 antigen | <immunology> Human histocompatibility (HLA) surface antigen encoded by the b locus on chromosome 6. There is a weak association between the presence of the HLA-b7 antigen and the diseases of narcolepsy and idiopathic haemochromatosis. HLA-b7 is in linkage disequilibrium with HLA-a3 and HLA-dr2. (12 Dec 1998) |
| HLA-b8 antigen | <immunology> Human histocompatibility (HLA) surface antigen encoded by the b locus on chromosome 6. It is in linkage disequilibrium with HLA-a1 and HLA-dr3. This explains the fact that though HLA-b8 was originally associated with several diseases, including coeliac disease, dermatitis herpetiformis, and myasthenia gravis, their association with HLA-dr3 is now considered more significant. (12 Dec 1998) |
| HLA-dr1 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. (12 Dec 1998) |
| HLA-dr2 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. It is in linkage disequilibrium with HLA-a3 and HLA-b7 and is strongly associated with goodpasture syndrome, multiple sclerosis, and narcolepsy. (12 Dec 1998) |
| HLA-dr3 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. It is in linkage disequilibrium with HLA-a1 and HLA-b8. The HLA-dr3 antigen is strongly associated with coeliac disease, grave's disease, dermatitis herpetiformis, early-age onset myasthenia gravis, systemic lupus erythematosus, juvenile diabetes, and opportunistic infections in aids. (12 Dec 1998) |
| HLA-dr4 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. It is strongly associated with rheumatoid arthritis and juvenile diabetes. (12 Dec 1998) |
| HLA-dr5 antigen | <immunology> Human immune-response, d-related antigen encoded by the d-locus on chromosome 6 and found on lymphoid cells. It is associated with kaposi sarcoma in aids and juvenile rheumatoid arthritis. (12 Dec 1998) |
| HLA-dr6 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. (12 Dec 1998) |
| HLA-dr7 antigen | <immunology> Human immune-response, d-related antigen encoded by the d locus on chromosome 6 and found on lymphoid cells. It is strongly associated with coeliac disease and psoriasis vulgaris. (12 Dec 1998) |
| homologous antigen | <immunology> A homologous antigen is one which will attract and react with a specific antibody. (09 Oct 1997) |
| self antigen | <immunology> The antigens of an organisms own cells and cell products are self antigens to the immune system of that organisn. Clones of immune cells reactive with self antigens are normally eliminated. (18 Nov 1997) |
| senescent cell antigen | <immunology> An antigen (62 kD) that appears on the surface of senescent erythrocytes and is immunologically cross reactive with isolated Band III protein. Seems to be recognised by an autoantibody and the immunoglobulin coated erythrocyte is then removed from circulation by cells such as Kuppfer cells of the liver that have Fc receptors. Intracellular cleavage of intact band III by a calcium activated protease, calpain, may reveal the antigen in situ. (18 Nov 1997) |
| sensitised antigen | The complex formed when antigen combines with specific antibody; so called because the antigen, by the mediation of antibody, is rendered sensitive to the action of complement. (05 Mar 2000) |
