The objective of this study is to investigate the role of intracellular chloride concentration ([Cl-]i) in insulin secretion in vivo and in vitro.
The maintenance of high [Cl-]i in insulin-secreting pancreatic β-cells plays an important role in glucose-induced depolarization and insulin secretion. Insulinotropic glucose concentrations i.e., >6 mM induces electrical activity in β-cells which results in insulin secretion. This electrical activity is mainly due to electrogenic efflux of Cl- from β-cells through volume-regulated anion channels (VRAC). The solute carrier family 12 group A member 1 (Slc12a1) and 2 (Slc12a2) encode several splice variants of the …
