dendritic cells

dendritic cells
(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.
