Pancreatic duct secretion: experimental methods, ion transport mechanisms and regulation

ABSTRACT

The pancreatic ductal tree conveys enzymatic acinar products to the duodenumand secretes the fluid and ionic components of pancreatic juice. The physiology ofpancreatic duct cells has been widely studied, but many questions are still unansweredconcerning their mechanisms of ionic transport. Differences in the transportmechanisms operating in the ductal epithelium has been described both among differentspecies and in the different regions of the ductal tree. In this review we summarizethe methods developed to study pancreatic duct secretion both in vivo and invitro, the different mechanisms of ionic transport that have been reported to date inthe basolateral and luminal membranes of pancreatic ductal cells and the regulationof pancreatic duct secretion by nervous, endocrine and paracrine influences(AU)
