Paracrine insulin action modulates the function and survival of islet endocrine cells (Figure 2-3). (interviewarea.com)
The majority of islet cells are closely apposed to the vasculature and to islet cells of opposing types, suggesting an important role for endocrine (via the microcirculation) and/or intra-islet paracrine (via the interstitium) effects on hormone release ( Figure 18-1 ). (mhmedical.com)

As a result, endocrine signaling requires more time than neural signaling to prompt a response in target cells, though the precise amount of time varies with different hormones. (bccampus.ca)

By comparing the pancreatic cells of type 2 diabetic human donors with those of healthy people, researchers at the University of Geneva (UNIGE) and at the University Hospitals of Geneva (HUG), Switzerland, were able to demonstrate, for the first time, that the pancreatic islet cells derived from the Type 2 Diabetic human donors bear compromised circadian oscillators.

In vitro, 25(OH)D induces the biosynthesis of insulin and insulin secretion in rat pancreatic islet cells [ 5 , 6 ],[ 7 ] . (researchsquare.com)
The fact that the pancreatic tissue is rich in zinc probably indicates that insulin remains stored in islet cells as a zinc salt. (biologydiscussion.com)
Insulin and glucagon , the two key hormones that orchestrate fuel storage and use, are produced by the islet cells in the pancreas. (mhmedical.com)

La secreción hormonal depende del tipo de CÉLULAS DE LOS ISLOTES presentes en los tumores: GLUCAGÓN de las CÉLULAS PANCREÁTICAS ALFA, INSULINA de las CÉLULAS PANCREÁTICAS BETA y SOMATOSTATINA de las CÉLULAS D. La mayoría son malignos exceptuando a los tumres productores de insulina (INSULINOMA). (bvsalud.org)

Cell surface proteins that bind pancreatic hormones with high affinity and trigger intracellular changes which influence the behavior of cells. (childrensmercy.org)

We previously exhibited that curcumin, a yellowish pigment isolated from turmeric, markedly raises GLP-1 secretion within the murine GLUTag cell collection [20]. (technuc.com)

Is insulin a catabolic hormone? (interviewarea.com)
While insulin is an anabolic hormone, glucagon is a catabolic hormone. (interviewarea.com)
Octreotide may quickly reverse anorexia and weight loss caused by the catabolic effect of glucagon excess. (msdmanuals.com)

Alpha cells are stimulated to produce glucagon in response to hypoglycemia, epinephrine, amino acids, other hormones, and neurotransmitters. (wikipedia.org)
The pancreatic form contains 29 amino acids and has a molecular weight of 3485 daltons, the gastric form contains 29 amino acids and has a molecular weight of 3500 daltons, and the enteric form, or enteroglucagon, contains a polypeptidic chain, has a high molecular weight, and is biologically and chemically different from other hormones, although it cross-reacts with them. (medscape.com)

Salivary glands secrete salivary amylase, which begins the chemical breakdown of carbohydrates by breaking the bonds between monomeric sugar units. (pressbooks.pub)

Recently some studies reveal that α-cells lacking DBP secrete less glucagon in response to low glucose concentration despite vitamin D sufficiency[10], and glucagon has a physiologic role to activate β-cells and enhance insulin secretion especially in the fed state [ 11 ] . (researchsquare.com)

Dibner said the study is the first proof that repairing compromised circadian clocks may improve pancreatic islet hormone secretion. (chroniclenewspaper.com)

In response to dietary sugars, incretins from the mammalian gut stimulate pancreatic cells to produce insulin and to suppress its counter-regulatory hormone glucagon. (tsukuba.ac.jp)
Octreotide injections partially suppress glucagon production and relieve the erythema, but glucose tolerance may also decrease because octreotide decreases insulin secretion. (msdmanuals.com)
