| 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) |
