| rt-PA | recombinant tissue-Plasminogen Activator = Alteplase |
|---|---|
| tPA | tissue Plasminogen Activator |
| AT | abdominal thrusts; achievement test; Achilles tendon; Achard-Thiers [syndrome]; adaptive thermogenes... |
| ATE | acute toxic encephalopathy; adipose tissue extract; autologous tumor extract |
| BALT | broncho-alveolar lavage fluid; bronchus-associated lymphoid tissue |
| antigens, human platelet | Human alloantigens expressed only on platelets, specifically on platelet membrane glycoproteins. These platelet-specific antigens are immunogenic and can result in pathological reactions to transfusion therapy. (12 Dec 1998) |
|---|---|
| antigens, ly | A group of lymphocyte surface antigens differentially located on subpopulations of mouse lymphocytes. This localization has been useful in distinguishing different functional subpopulations of lymphocytes. For example, cytotoxic T-cells bear primarily lyt-23 on their surface and not lyt-1, whereas helper cells bear lyt-1 and not lyt-23. (12 Dec 1998) |
| 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, 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 |
