WebGlucose is the undisputed main stimulus for the release of insulin, the main glucoregulatory hormone, from pancreatic beta cells. The beta cells respond to a ‘square wave’ glucose stimulus, either in vivo or in vitro with a biphasic pattern of insulin release, represented by a short (5–10 min) first phase, after which the secretion rate declines to about 30% of the … Webinsulin secretion in MIN6-K8 b-cells, suggesting that glutamate transport into insulin granules through VGLUT1 is required for incretin-induced insulin secretion 30.
