DENDRITIC CELLS

dendritic cells: translation

(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 gd -TCR receptors (dendritic epidermal cells: DECs).

(4) DOPA-positive cells derived from neural crest and found in the basal part of epidermis: melanocytes distinct from (3). See also Langerhans cells.
