Core Tip
Core tip: The acini–islet–acinar axis involves the inhibition of insulin production by amylase and the stimulation of amylase release by insulin, which is of particular importance with regards to glucose regulation. There is increasing evidence that amylase levels correspond to overall metabolic health, with low amylase levels being significantly associated with the development of metabolic syndrome, diabetes, and obesity. Disruption of the integrated glucose–insulin interactions by intrapancreatic arterial amylase infusion in the present study confirms the existence of an AIA reflex and justifies placement of the exocrine and endocrine pancreatic components within the same organ.
