Pancreatic polypeptide (PP) dose-dependently enhanced both basal and submaximally ACTH-stimulated corticosterone production by dispersed zona fasciculata/reticularis cells of the rat adrenal gland.

Abstract
Pancreatic polypeptide (PP) dose-dependently enhanced both basal and submaximally ACTH-stimulated corticosterone production by dispersed zona fasciculata/reticularis cells of the rat adrenal gland. Conversely PP did not affect either basal or ACTH- and angiotensin-II-stimulated aldosterone and corticosterone secretion of zona glomerulosa cells. These findings could throw light on the physiological significance of the marked increase in the pancreatic release of PP during stresses.
