Research Abstract |
Pancreatic juice is an alkaline fluid that contains HCO_3^- rich fluid and digestive enzymes. Na^+-H^+ exchangers (NHE) are localized in both basolateral and apical membranes of various epithelia. In the present study, to investigate the role of apical NHE in HCO_3^- secretion from pancreatic duct cells, we identified the membrane localization of apical Na^+-H^+ exchangers, measured the activity of apical Na^+-H^+ exchange, and demonstrated the mechanisms to play a role of HCO_3^- secretion by pancreatic ductal epithelium.
