| veil cell | An antigen-presenting cell that has veil-like cytoplasmic processes and circulates in the blood and lymph. Synonym: veiled cells. (05 Mar 2000) |
| veiled cell | A cell type found in afferent lymph and defined (rather unsatisfactorily) on the basis of its morphology. Probably an accessory cell migrating from the periphery (where it is referred to as a Langerhans cell if in the skin) to the draining lymph node. In the lymph node known as an interdigitating cell and found in the T dependent areas of spleen or lymph nodes, involved in antigen presentation (Class II MHC positive). Has high levels of surface Ia antigens. (18 Nov 1997) |

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

| 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) |
