Insulin Release - an overview ScienceDirect Topics

WebThe insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis. This pathway is also influenced by fed versus fasting states, stress levels, and a variety of other hormones.

WebInsulin and C-peptide are stored in secretory vesicles which upon stimulation by glucose and other secretagogues, are released at equimolar concentration [58]. Following secretion, insulin and the C-peptide pass through the liver. In contrast to insulin, the C-peptide has a longer half-life (30–35 min) [57]. WebThe β cell is electrically excitable; in response to an elevation of glucose, it depolarizes and starts generating action potentials. The electrophysiology of mouse β cells and the cell's role in insulin secretion have been extensively investigated. More recently, similar studies have been performed on human β cells.

WebInsulin is stored in large dense core vesicles and released by exocytosis, a multistage process involving transport of vesicles to the plasma membrane, their docking, priming and finally their fusion with the plasma membrane. Some of the protein components necessary for this process have been identified in beta cells.
