| receptors, antigen | Molecules on the surface of b- and T-lymphocytes that recognise and combine with specific antigens. (12 Dec 1998) |
|---|---|
| receptors, antigen, B-cell | Immunoglobulin molecules on the surface of B-lymphocytes that recognise and bind antigen. (12 Dec 1998) |
| receptors, antigen, T-cell | Molecules on the surface of T-lymphocytes that recognise and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (antigens, CD3). Recognition of foreign antigen and the major histocompatibility complex is accomplished by a single heterodimeric antigen-receptor structure, composed of either alpha-beta (receptors, antigen, T-cell, alpha-beta) or gamma-delta (receptors, antigen, T-cell, gamma-delta) chains. (12 Dec 1998) |
| receptors, antigen, T-cell, alpha-beta | T-cell receptors composed of CD3-associated alpha and beta polypeptide chains and expressed primarily in CD4+ or CD8+ T-cells. Unlike immunoglobulins, the alpha-beta T-cell receptors recognise antigens only when presented in association with major histocompatibility (MHC) molecules. (12 Dec 1998) |
| receptors, antigen, T-cell, gamma-delta | T-cell receptors composed of CD3-associated gamma and delta polypeptide chains and expressed primarily in CD4-/CD8- T-cells. The receptors appear to be preferentially located in epithelial sites and probably play a role in the recognition of bacterial antigens. The T-cell receptor gamma/delta chains are separate and not related to the gamma and delta chains which are subunits of CD3 (see antigens, CD3). (12 Dec 1998) |
| receptors, very late antigen | Members of the integrin family appearing late after T-cell activation. They are a family of proteins initially identified at the surface of stimulated T-cells, but now identified on a variety of cell types. At least six vla antigens have been identified as heterodimeric adhesion receptors consisting of a single common beta-subunit and different alpha-subunits. (12 Dec 1998) |
| Gerbich antigen | glycophorin C |
| Vi antigen | Virulence antigen, an external capsular antigen of enterobacteria formerly thought to be related to increased virulence. (05 Mar 2000) |
| viral antigen | Those antigens specified by the viral genome (often coat proteins) that can be detected by a specific immunological response. Often of diagnostic importance. (18 Nov 1997) |
| C carbohydrate antigen | An antigen found in the cell wall of Streptococcus pneumoniae. See: beta-haemolytic streptococci. (05 Mar 2000) |
| CD antigen | <immunology> Differentiation antigens residing on human leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similiar reactivity with certain subpopulations of antigens. The subpopulations of antigens are also known by the same CD designation. (12 Dec 1998) |
| Rhus toxicodendron antigen | An extract of fresh leaves of poison ivy, with 0.4% of procaine hydrochloride; used by intradermal injection to determine sensitiveness to the poison of Rhus toxicodendron. (05 Mar 2000) |
| Rhus venenata antigen | An extract of fresh leaves of poison sumac; used to determine sensitiveness to the plant or to relieve the dermatitis caused by contact with its leaves. (05 Mar 2000) |
| cholesterinised antigen | Cardiolipin to which cholesterol has been added. (05 Mar 2000) |
| rotavirus antigen test | <investigation, microbiology> A test which detects the presence of rotavirus in the stool. This virus is a common cause of childhood gastroenteritis. (17 Dec 1997) |
