Interaction Information:

Comment Glucose is the most important physiological secretagogue for insulin. The beta-cell is thus poised to convert small fluctuations in blood glucose concentration (typically from 4.5 to 8 mM in man) into large changes in insulin secretion within minutes.

Comment Within beta-cells, newly synthesized insulin is first produced as the prohormone proinsulin, and converted into mature insulin through the action of prohormone convertases (PC1, PC2, encoded by Pcsk1 and Pcsk2, respectively) during trafficking through the secretory pathway.

Comment Active insulin is stored in dense core secretory granules (5‚Äď10000 per cell), each containing 300000 or more molecules of insulin. The tightly-regulated release of only a fraction of the granules through exocytosis (2 % per hour at maximal glucose concentrations) is sufficient to achieve regulation of blood glucose levels within the above narrow physiological range. This tight regulation is important not only to prevent hyperglycemia, but equally to suppress the potentially lethal hypoglycemia which would accompany over-secretion of insulin.

Comment Central to glucose sensing by beta-cells is the stimulation of glycolytic and oxidative metabolism of the sugar, ultimately causing enhanced mitochondrial ATP synthesis. Thus, flux through alternative pathways including the pentose phosphate shunt is usually small, though it may be increased under some circumstances. Increases in total, as well as free cytosolic mitochondrial matrix and sub-plasma membrane ATP/ADP ratios then lead to the closure of ATP-sensitive K + (KATP ) channels. The unbalanced influx of positively charged ions, notably Na + , then leads to plasma membrane depolarization, the firing of action potentials and the opening of voltage-gated Ca2 + channels. This, in turn, prompts the activation of secretory granule-associated small N- ethylmaleimide-sensitive factor receptor (SNARE) proteins and granule fusion with the plasma membrane. Highly localized changes in free Ca2 +, for example at the inner surface of the plasma membrane, at the mouth of voltage-gated calcium channels, and at the surface of secretory granules, are also believed to be important in controlling this process. Calcium release from intracellular organelles including the ER (endoplasmic reticulum) and Golgi [mediated via IP3 (inositol 1,4,5-trisphosphate)] as well as secretory granules and other acidic stores including lysosomes (via the generation of nicotinic acid‚Äďadenine dinucleotide phosphate, NAADP), may also be involved. Although this is a contested area this description summarizes the essentials of the ‚Äėcanonical‚Äô pathway for glucose-stimulated insulin secretion.

Comment The incretins act via specific G [Gs ] protein-coupled receptors (GPCRs, e.g. GLP1R and GIPR) on the beta-cell surface to increase intracellular cAMP concentrations, activating protein kinase A (PKA), as well as exchange protein activated by cAMP 2 (EPAC2) and other signalling pathways (mediated, for example, by beta arrestin and MAPK). Acetyl-choline, acting through muscarinic M3 receptors, and ATP (via P2X and P2Y purinoreceptors), as well as fatty acids (via GPR40/FFAR1), and vasopressin, also enhance secretion triggered by nutrients by increasing cytosolic Ca2 + , whereas vasoactive intestinal peptide (VIP), PYY and oxyntomodulin probably act via cAMP.

Comment Inhibitors of secretion include somatostatin, which acts in part via an inhibitory G protein, adrenaline (epinephrine) and noradrenaline (norepinephrine), the latter acting through alpha2 receptors to open KATP channels and hyperpolarize the cell. The actions of epinephrine (and norepinephrine) are important to suppress insulin release during exercise.

Comment The identification in islets of a high Michaelis constant, and cooperative HK (hexokinase) type IV, GK (glucokinase), encoded by GCK, present alongside higher affinity hexokinases, suggests that glucose phosphorylation is the key flux-generating step. Subsequent studies revealed that the higher affinity HKs are largely absent from highly purified beta-cells. Importantly, and providing direct evidence for the importance of GK in controlling insulin secretion in man, mutations in the human GCK gene lead to monogenic diabetes (maturity onset diabetes of the young-2; MODY2).

Comment Demonstrating the importance of mitochondrial metabolism in the regulation of insulin secretion in man, abnormalities in the expression of the mitochondrial genome are associated with impaired insulin secretion in maternally-inherited diabetes and deafness (tRNALeu mutation).
