| gene rearrangement, gamma-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the gamma-chain of antigen receptors. (12 Dec 1998) |

| paraluteal cell | A steroid secretory cell of the corpus luteum that comes from the theca interna of the ovarian follicle at the time of ovulation. Synonym: paraluteal cell, paralutein cell. (05 Mar 2000) |
| paralutein cell | A steroid secretory cell of the corpus luteum that comes from the theca interna of the ovarian follicle at the time of ovulation. Synonym: paraluteal cell, paralutein cell. (05 Mar 2000) |
| reactive cell | <cell biology> A round to oval astrocyte cell with abundant cytoplasm containing glial filaments and an eccentric nucleus; may contain two nuclei in the cell hypertrophy of astrocytes. Synonym: gemistocyte, gemistocytic cell, reactive astrocyte, reactive cell. (05 Mar 2000) |
| genes, T-cell receptor | DNA sequences, in cells of the t-lymphocyte lineage, that code for T-cell receptors. The tcr genes are formed by somatic rearrangement (see gene rearrangement, t-lymphocyte and its children) of germline gene segments, and resemble ig genes in their mechanisms of diversity generation and expression. (12 Dec 1998) |
| genes, T-cell receptor alpha | DNA sequences encoding the alpha chain of the T-cell receptor. The genomic organization of the tcr alpha genes is essentially the same in all species and is similar to the organization of ig genes. (12 Dec 1998) |
| genes, T-cell receptor beta | DNA sequences encoding the beta chain of the T-cell receptor. The genomic organization of the tcr beta genes is essentially the same in all species and is similar to the organization of ig genes. (12 Dec 1998) |
| genes, T-cell receptor delta | DNA sequences encoding the delta chain of the T-cell receptor. The delta-chain locus is located entirely within the alpha-chain locus. (12 Dec 1998) |
| genes, T-cell receptor gamma | DNA sequences encoding the gamma chain of the T-cell receptor. The human gamma-chain locus is organised similarly to the tcr beta-chain locus. (12 Dec 1998) |
| Marchand's wandering cell | A cell of the mononuclear phagocyte system. (05 Mar 2000) |
| receiver cell | <plant biology> Cells in the photosynthetic tissues of plants into which the solutes from xylem are pumped. (18 Nov 1997) |
| receptor-CD3 complex, antigen, T-cell | Molecule composed of the non-covalent association of the T-cell antigen receptor (receptors, antigen, T-cell) with the CD3 complex (antigens, CD3). This association is required for the surface expression and function of both components. The molecule consists of up to seven chains: either the alpha/beta or gamma/delta chains of the T-cell receptor, and four or five chains in the CD3 complex. (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) |
