APUD cells

acronym for amine and precursor uptake and decarboxylation (see also: apudocytes). A collective term for a diffuse spectrum of endocrine cell types scattered throughout the body. APUD cells constitute a component of a universal diffuse neuroendocrine system (neuroimmunoendocrine system; see also: neuroimmune network) (Polack and Blom, 1986; Sternber, 2000). Histologically, these cells can be identified by their staining behaviour (see: chromaffin, chomophil cells)

These cells are located in the gut, pancreas, urogenital tract, airway epithelium, pineal gland, thyroid gland, adrenals, adenohypophysis and hypothalamus, carotid body, skin, sympathetic ganglia ... ... ... ...
