First phase insulin secretion
WebTwo phases of insulin secretion are widely known: the first-phase insulin secretion (FPIS) and the second-phase insulin secretion (SPIS). The FPIS is normally secreted by the β -cells within 10 min after being exposed to an acute rise in plasma glucose levels to reduce their emission [ 5 ], whereas the SPIS is the newly secreted insulin from ...
