Desensitization of insulin secretion
Biochemical Pharmacology, 2002Desensitization of insulin secretion describes a reversible state of decreased secretory responsiveness of the pancreatic beta-cell, induced by a prolonged exposure to a multitude of stimuli. These include the main physiological stimulator, glucose, but also other nutrients like free fatty acids and practically all pharmacological stimulators acting by

Multiscale Modeling of Insulin Secretion
IEEE Transactions on Biomedical Engineering, 2011Insulin secretion from pancreatic beta cells is a fundamental physiological process, and its impairment plays a pivotal role in the development of diabetes. Mathematical modeling of insulin secretion has a long history, both on the level of the entire body and on the cellular and subcellular scale.

Ovarian tumors secreting insulin
Endocrine, 2015Combined ovarian germ cell and neuroendocrine tumors are rare. Only few cases of hyperinsulinism due to ovarian ectopic secretion have been hypothesized in the literature. An ovarian tumor was diagnosed in a 76-year-old woman, referred to our department for recurrent hypoglycemia with hyperinsulinism.

Inhibition of Insulin Secretion
2005Reports of the effects of amylin and amylin agonists on insulin secretion have varied widely. Some confusion can be attributed to the use of human amylin, which has been shown to readily fall out of solution resulting in low estimates of bioactivity. Some confusion can be resolved by assessing the probability that this had happened. The view taken here,

Effects of Aging on Insulin Secretion
Diabetes, 1989Aging is associated with hyperinsulinemia, but reports vary on the contributions of altered insulin clearance versus insulin secretion to this phenomenon. To elucidate the role of insulin secretion in the hyperinsulinemia of aging, 10 elderly (age 66 ± 4 yr, body mass index 25 ± kg/m2) and 8 young (age 30 ± 5 yr, body mass index 24 ± 3 kg/m2) subjects ...

Metabolism, 1984
Recent advances in insulin secretion indicate that pertussis toxin abolishes the inhibition by alpha 2 adrenoceptor activation of insulin release by the pancreas. Pertussis toxin adenosine diphosphate (ADP) ribosylates an inhibitory guanine nucleotide-binding protein (Ni) involved in inhibition of adenylate cyclase.

Mitochondrial function and insulin secretion
Molecular and Cellular Endocrinology, 2013In the endocrine fraction of the pancreas, the β-cell rapidly reacts to fluctuations in blood glucose concentrations by adjusting the rate of insulin secretion. Glucose-sensing coupled to insulin exocytosis depends on transduction of metabolic signals into intracellular messengers recognized by the secretory machinery.
