| dendritic cell | 1. Follicular dendritic cells, found in germinal centres of spleen and lymph nodes, retain antigen for long periods. 2. Accessory (antigen presenting) cells, positive for Class II histocompatibility antigens, found in the red and white pulp of the spleen and lymph node cortex and associated with stimulating T-cell proliferation. 3. T lymphocyte found in epidermis and other epithelial cells involved in antigen recognition expressing predominantly __TCR receptors (dendritic epidermal cells: DECs). (4) Dopa positive cells derived from neural crest and found in the basal part of epidermis. (13 Nov 1997) |
| dendritic cells | Immunocompetent cells of the lymphoid and haemopoietic systems and skin. They are also called interdigitating, reticular, and veiled cells. They function morphologically and phenotypically by presenting or processing antigens, thereby stimulating cellular immunity. (12 Dec 1998) |
| dendritic corneal ulcer | Keratitis caused by herpes simplex virus. (05 Mar 2000) |
| dendritic depolarisation | The loss of a negative charge in the dendrites of a nerve cell. (05 Mar 2000) |
| dendritic keratitis | <pathology> Inflammation of the cornea (and conjunctiva) due to herpes virus type I, a characteristic finding on physical examination of the eye (cornea) is a dendritic pattern (crystalline or tree-like pattern). (27 Sep 1997) |
| dendritic process | A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body, unlike an axon that carries electrical signals away from the cell body. Each nerve cell usually has many dendrites. This classical definition, however, lost some weight with the discovery of axo-axonal and dendro-dendritic synapses. (29 Sep 1997) |
| dendritic spine | Wine glass or mushroom shaped protrusions from dendrites that represent the principal site of termination of excitatory afferent neurons on interneurons, especially in the cortical regions. (18 Nov 1997) |
| dendritic spines | Variably long excrescences of nerve cell dendrites, varying in shape from small knobs to thornlike or filamentous processes, usually more numerous on distal dendrite arborizations than on the proximal part of dendritic trunks; they are a preferential site of synaptic axodendritic contact; sparse or absent in some types of nerve cells (motor neurons, the large cells of the globus pallidus, stellate cells of the cerebral cortex), exceedingly numerous in others such as the pyramidal cells of the cerebral cortex and the Purkinje cells of the cerebellar cortex. Synonym: dendritic thorns, gemmule. (05 Mar 2000) |

| dendritic tree | Characteristic (tree like) pattern of outgrowths of neuronal dendrites. (18 Nov 1997) |
| keratitis, dendritic | A form of herpetic keratitis characterised by the formation of small vesicles which break down and coalesce to form recurring dendritic ulcers, characteristically irregular, linear, branching, and ending in knoblike extremities. (12 Dec 1998) |
| follicular dendritic cell | <pathology> A virus-trapping dendritic cell found in lymph node follicles (germinal centres). See: Germinal Centre and Dendritic Cell. (09 Oct 1997) |
