| APUD | <pharmacology, physiology> Paracrine cells of which argentaffin cells are an example. Usage of the term APUD is neither helpful nor memorable. Acronym: APUD (11 Nov 1997) |

| APUD cell | <pathology> A group of apparently unrelated endocrine cells found throughout the body which have a number of similar characteristics and which make a number of hormones with similar structures (including serotonin, epinephrine, dopamine, neurotensin, and norepinephrine. See: Amine Precursor Uptake and Decarboxylation. (10 Jan 1998) |
| apud cells | Cells derived from primitive cell types in the neural crest. During ontogeny they migrate to the foregut and specific locations of the neuroendocrine system. Properly located these cells form part of the normal hormone producing tissues of the neuroendocrine system. If misdirected these cells may become hyperplastic, adenomatous, or malignant (cf. Apudoma). (12 Dec 1998) |
| apudoma | <oncology, tumour> A tumour composed of APUD cells and which secretes one or more hormones or amines. (09 Oct 1997) |

| APUD c.’s |
amine precursor uptake and decarboxylation cells: a diffuse group of cells, many originating in the neural crest, that share certain cytochemical and ultrastructural characteristics and are found scattered throughout the body; types include melanocytes, the cells of the chromaffin system, and cells in the hypothalamus, hypophysis, thyroid, parathyroids, lungs, gastrointestinal tract, and pancreas. They concentrate the amino acid precursors of certain amines and decarboxylate them to form the amines, which function as regulators and neurotransmitters. They produce substances such as epinephrine, norepinephrine, dopamine, serotonin, enkephalin, somatostatin, neurotensin, and substance P, the actions of which may affect contiguous cells, nearby groups of cells, or distant cells, thus functioning as local or systemic hormones. See also basal granular c's.
