| 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, 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, t-independent | Antigens which may directly stimulate b lymphocytes without the cooperation of t lymphocytes. (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) |
| CDE antigens | rh blood group |
| CENP antigens | <molecular biology> Proteins of the kinetochore (CENP A 27 kD, CENP B 80 kD, CENP C 140 kD and CENP D 50 kD) that react strongly with antibodies from CREST sera. (18 Nov 1997) |
| Gm antigens | Allotypic determinants (antigens) that are present on the heavy chain of immunoglobulin G. There are 25 different determinants present throughout the human population. (05 Mar 2000) |
| Rh antigens | rh blood group |
| group antigens | Antigen's that are shared by related genera of microorganisms. (05 Mar 2000) |
| class I antigens | Cell membrane bound glycoproteins that are coded by genes of the major histocompatibility complex. (05 Mar 2000) |
| class II antigens | A cell membrane glycoprotein encoded by genes of the major histocompatibility complex. These antigens are distributed on antigen-presenting cells such as macrophages, B-cells, and dendritic cells. (05 Mar 2000) |
| class III antigens | Non-cell membrane molecules that are encoded by the S region of the major histocompatibility complex. These antigens are not involved in determining histocompatibility and include the complement proteins. (05 Mar 2000) |
