Pancreatic islet β-cell plays an essential role in insulin release and hence glucose homeostasis. The maintenance of glucose homeostasis depends on β-cell ability to cope with enough insulin to fulfill metabolic and physiological demands. Adequate insulin release is the result of highly complex and dynamic interplays between acute changes in β- cell electrical activity, exocytosis and chronic adaptations in cellular function, volume, mass and proliferation. All of this appears modulated, to some extent, by the functional presence of Slc12a2 symporters, also known as Na+K+2Cl– cotransporter-1 (Nkcc1), which accumulates intracellular Cl– above its electrochemical equilibrium. Recent studies from our laboratory showed …
