Actions of the major digestive hormones secreted by APUD cells
APUD cells (DNES cells) constitute a group of apparently unrelated endocrine cells, which were named by the scientist , who developed the APUD concept in the early 1960s. These cells share the common function of secreting a low molecular weight polypeptide hormone. There are several different types which secrete the hormones secretin, cholecystokinin and several others. The name is derived from an acronym, referring to the following:[1][2]
- Amine Precursor Uptake – for high uptake of amine precursors including 5-hydroxytryptophan (5-HTP) and dihydroxyphenylalanine (DOPA).[2]
- Decarboxylase – for high content of the enzyme amino acid decarboxylase (for conversion of precursors to amines).
