| antigens, neoplasm | Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumour cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin. (12 Dec 1998) |
|---|---|
| antigens, polyomavirus transforming | Polyomavirus antigens which cause infection and cellular transformation. The large t antigen is necessary for the initiation of viral DNA synthesis, repression of transcription of the early region and is responsible in conjunction with the middle t antigen for the transformation of primary cells. Small t antigen is necessary for the completion of the productive infection cycle. (12 Dec 1998) |
| antigens, protozoan | Any part or derivative of any protozoan that elicits immunity; malaria (plasmodium) and trypanosome antigens are presently the most frequently encountered. (12 Dec 1998) |
| antigens, surface | Antigens on surfaces of cells, including infectious or foreign cells or viruses. They are usually protein-containing groups on cell membranes or walls and may be isolated. (12 Dec 1998) |
| antigens, t-independent | Antigens which may directly stimulate b lymphocytes without the cooperation of t lymphocytes. (12 Dec 1998) |
| antigens, thy-1 | A group of differentiation surface antigens, among the first to be discovered on thymocytes and T-lymphocytes. Originally identified in the mouse, they are also found in other species including humans, and are expressed on brain neurons and other cells. (12 Dec 1998) |
| antigens, tumour-associated, carbohydrate | Carbohydrate antigens expressed by malignant tissue. They are useful as tumour markers and are measured in the serum by means of a radioimmunoassay employing monoclonal antibodies. (12 Dec 1998) |
| antigens, viral | Substances elaborated by viruses that have antigenic activity. (12 Dec 1998) |
| antigens, viral, tumour | Those proteins recognised by antibodies from serum of animals bearing tumours induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation. (12 Dec 1998) |
| K antigens | <haematology, immunology> Blood type classification based on a group of erythrocyte antigens that is characterised by an antibody called anti-K. Multiple erythrocytic antigens that comprise at least three pairs of alternates and amorphs, determined by one complex gene or possibly several genes at closely linked loci. The system is important in transfusion reactions. Its expression involves the X chromosome. (21 Jun 2000) |
|---|---|
| Le antigens | <haematology> A pair of blood group activities associated with the A, B, H substances. Lewis Lea is a separate gene, whereas Leb arises from the combined activity of the enzymes specified by Le(a) and H genes. (18 Nov 1997) |
| Lu antigens | A complex blood group system having pairs of alternate antigens and amorphic genes, but also subject to a dominant independently segregating repressor. (12 Dec 1998) |
| Lyt antigens | A group of alloantigens that are present on either T or B murine lymphocytes, e.g., Lyt 2,3 is equivalent to human CD8. (05 Mar 2000) |
