Identification of the D1-cell as the source of human pancreatic polypeptide (HPP)
Gut
|October 1, 1976
Abstract:
Immunoperoxidase positive HPP-producing cells have been examined ultrastructurally using the serial semithin-thin section technique. The features of the HPP cells were found to be identical with those of the previously described D1-cell. The D1-cells are scattered throughout the exocrine parenchyma and occur to a minor extent in the islets.

Cells and Secretions of the Pancreas
The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
