Experiments show GLP-1 and secretin improve fluid secretion in guinea-pig pancreatic duct cells, indicating their crucial roles.

This research aims to investigate the effects of GLP-1, glucagon, and secretin on fluid secretion in pancreatic duct cells.
Measured fluid secretion rate in isolated duct segments from guinea pigs
Monitored cAMP production via ELISA
Analyzed messenger RNA expression of receptors by quantitative reverse transcriptase-polymerase chain reaction
GLP-1 and secretin stimulated fluid secretion in a concentration-dependent manner
GIP required higher concentrations for stimulation, while glucagon exhibited weaker effects
GLP-1 significantly increased cAMP production in pancreatic ducts

FURUHASHI-HIGUCHI et al. (2026) studied this question.
