LRRC8/VRAC anion channels enhance β-cell glucose sensing and insulin secretion

Abstract

Insulin secretion by β-cells is stimulated by glucose and is dependent on the induction of β-cell membrane depolarization, mainly driven by the closure of KATP channels, which in turn promotes voltage-gated Ca2+ channel opening. Here the authors show that LRRC8 volume-regulated anion channels (VRACs) modulate glucose-stimulated calcium increase and insulin secretion.
