Langerhans cells

(redirected from interdigitating dendritic cells)

Lan·ger·hans cells

(lahng'ĕr-hahnz),
1. dendritic clear cells in the epidermis, containing distinctive granules that appear rod- or racket-shaped in section, but lacking tonofilaments, melanosomes, and desmosomes; they carry surface receptors for immunoglobulin (Fc) and complement (C3), and are believed to be antigen fixing and processing cells of monocytic origin; active participants in cutaneous delayed hypersensitivity. Synonym(s): interdigitating dendritic cells
2. cells seen in eosinophilic granuloma and lymphoma of the lungs.
Synonym(s): dendritic cell

Langerhans cells

cells involved in the presentation of antigens to bring about an immune response; such cells are found in the skin and the gastrointestinal tract.

Langerhans,

Paul, German anatomist, 1847-1888.
islets of Langerhans - cellular masses composed of different cell types that comprise the endocrine portion of the pancreas and are the source of insulin and glucagon. Synonym(s): islet tissue; Langerhans islands; pancreatic islands; pancreatic islets
Langerhans cell granulomatosis
Langerhans cells - dendritic clear cells in the epidermis that are active participants in cutaneous delayed hypersensitivity.
Langerhans granule - a small membrane-bound granule first reported in Langerhans cells of the epidermis. Synonym(s): Birbeck granule
Langerhans islands - Synonym(s): islets of Langerhans

Langerhans cells

population of dendritic cells within epidermal stratum granulosum; function as antigen-presenting cells

The paracortex predominantly consists of small mature T cells as well as variable numbers of large transformed immunoblasts (T cells or B cells), interdigitating dendritic cells, plasmacytoid dendritic cells, and high endothelial venules (Figure 1, E).
E, Paracortex composed of numerous small mature T lymphocytes, scattered interdigitating dendritic cells, occasional immunoblasts (short arrow), and high endothelial venules (long arrow).
Follicular dendritic cells, interdigitating dendritic cells, and Langerhans cells are the major nonphagocytic antigen-presenting accessory cells of the immune system.
