| antigens, CD19 | <immunology> Differentiation antigens expressed on B-lymphocytes and B-cell precursors. They are involved in regulation of B-cell proliferation. (12 Dec 1998) |
|---|---|
| antigens, CD2 | <immunology> Glycoprotein members of the immunoglobulin superfamily which participate in T-cell adhesion and activation. They are expressed on most peripheral T-lymphocytes, natural killer cells, and thymocytes, and function as co-receptors or accessory molecules in the T-cell receptor complex. (12 Dec 1998) |
| antigens, CD20 | <immunology> Unglycosylated phosphoproteins expressed only on B-cells. They are regulators of transmembrane calcium conductance and thought to play a role in B-cell activation and proliferation. (12 Dec 1998) |
| antigens, CD26 | <enzyme, immunology> Cell-surface glycoproteins and serine protease, also known as dipeptidyl-peptidase IV, that play a role in t-lymphocyte activation. Cd26 binds to adenosine deaminase on the T-cell surface. Registry number: EC 3.4.14.5 (12 Dec 1998) |
| antigens, CD27 | <immunology> Dimeric membrane glycoproteins found on most T-lymphocytes. Activation of T-cells by the antigen receptor increases CD27 surface expression. (12 Dec 1998) |
| antigens, CD28 | <immunology> T-cell differentiation antigens that serve as the receptors for the b7 antigen (antigens, CD80) which modulates T-cell lymphokine production. (12 Dec 1998) |
| antigens, CD29 | <immunology> Integrin beta-1 chains which are expresssed as heterodimers noncovalently associated with specific alpha-chains of the CD49 family (CD49a-f). Cd29 is expressed on resting and activated leukocytes and is a marker for total very late activation antigens on cells. (barclay et al., the leukocyte antigen factsbook, 1993, p164) (12 Dec 1998) |
| antigens, CD4 | <immunology> 55-kD glycoproteins originally defined as differentiation antigens on T-lymphocytes, but also found on other cells including monocytes/macrophages. CD4 antigens are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MHC (major histocompatibility complex) class II-restricted immune responses. On T-lymphocytes they define the helper/inducer subset. Cd4 antigens also serve as HIV receptors, binding directly to the envelope protein gp120 on HIV. The protein structure on the surface of a human cell that allows HIV to attach, enter, and thus infect a cell. CD4 receptors are present on CD4 cells (helper T-cells), macrophages and dendritic cells, among others. Normally, CD4 acts as an accessory molecule, forming part of larger structures (such as the T-cell receptor) through which Tcells and other cells signal each other. (12 Dec 1998) |
| antigens, CD40 | <immunology> Differentiation antigens found on all mature B-lymphocytes and some epithelial cells, carcinomas, and lymphoid dendritic cells. This is a member of the tumour necrosis factor superfamily. Evidence suggests that CD40-dependent activation of B-cells is important for generation of memory B-cells within the germinal centres. (12 Dec 1998) |
| antigens, CD44 | <immunology> Acidic sulfated integral membrane glycoproteins expressed in several alternatively spliced and variable glycosylated forms on a wide variety of cell types including mature T-cells, B-cells, medullary thymocytes, granulocytes, macrophages, erythrocytes, and fibroblasts. Cd44 antigens are the principle cell surface receptors for hyaluronate and this interaction mediates binding of lymphocytes to high endothelial venules. (12 Dec 1998) |
| antigens, CD45 | <immunology> High-molecular weight glycoproteins uniquely expressed on the surface of all leukocytes and their haemopoietic progenitors. The CD45 family consists of multiple members that are all products of a single gene. Cd45 expression is necessary for signalling through the T-cell receptor. (12 Dec 1998) |
| antigens, CD5 | <immunology> Glycoproteins expressed on all mature T-cells, thymocytes, and a subset of mature B-cells. Antibodies specific for CD5 can enhance T-cell receptor-mediated T-cell activation. The B-cell-specific molecule CD72 is a natural ligand for CD5. (12 Dec 1998) |
| antigens, CD55 | <immunology> Glycoproteins broadly distributed among haematopoietic and non-haematopoietic cells. Cd55 prevents the assembly of c3 convertase or accelerates the disassembly of preformed convertase, thus blocking the formation of the membrane attack complex. (12 Dec 1998) |
| antigens, CD56 | <immunology> The 140-kD isoform of ncam (neural cell adhesion molecule) containing a transmembrane domain and short cytoplasmic tail. It is expressed by all lymphocytes mediating non-MHC restricted cytotoxicity and is present on some neural tissues and tumours. (12 Dec 1998) |
| antigens, CD57 | <immunology> Oligosaccharide antigenic determinants found principally on nk cells and T-cells. Their role in the immune response is poorly understood. (12 Dec 1998) |
