Histologic distribution of insulin and glucagon receptors

Brazilian Journal of Medical and Biological Research, 1998
Insulin and glucagon are the hormonal polypeptides secreted by the B and A cells of the endocrine pancreas, respectively. Their major physiologic effects are regulation of carbohydrate metabolism, but they have opposite effects. Insulin and glucagon have

Variation in responses to incretin therapy: Modifiable and non-modifiable factors

Frontiers in Molecular Biosciences, 2023
Type 2 diabetes (T2D) and obesity have reached epidemic proportions. Incretin therapy is the second line of treatment for T2D, improving both blood glucose regulation and weight loss.

The Insulin Receptor Talks to Glucagon? [PDF]

Cell Metabolism, 2009
Type 2 diabetes (T2DM) is not only a disorder of impaired insulin secretion but also glucagon oversecretion. However, the link between the two remains unclear. Is it possible that the latter is a consequence of the former? In this issue, Kawamori et al. (2009) have addressed this question by generating alpha cell-specific insulin receptor knockout mice.

Hepatic glucagon receptors expression in response to glucose, insulin, glucagon and immune challenge in grass carp (Ctenophcuyngodon idellus)

Aquaculture Reports, 2020
Since discovery, glucagon biology has remained enigmatic. Studies have shown that glucagon may have physiological effects beyond glucose regulation by binding to its receptor (Gcgr).

Selective polypeptide ligand binding to the extracellular surface of the transmembrane domains of the class B GPCRs GLP-1R and GCGR

iScience, 2023
Summary: Crystal and cryo-EM structures of the glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR) bound with their peptide ligands have been obtained with full-length constructs, indicating that the extracellular domain (ECD) is ...

Glucagon-Like Peptide-1 Based Therapies: A New Horizon in Obesity Management [PDF]

Endocrinology and Metabolism
Obesity is a significant risk factor for health issues like type 2 diabetes and cardiovascular disease. It often proves resistant to traditional lifestyle interventions, prompting a need for more precise therapeutic strategies. This has led to a focus on

Human Beta Cells Produce and Release Serotonin to Inhibit Glucagon Secretion from Alpha Cells

Cell Reports, 2016
In the pancreatic islet, serotonin is an autocrine signal increasing beta cell mass during metabolic challenges such as those associated with pregnancy or high-fat diet.

Modulation of β-catenin signaling by glucagon receptor activation. [PDF]

PLoS ONE, 2012
The glucagon receptor (GCGR) is a member of the class B G protein-coupled receptor family. Activation of GCGR by glucagon leads to increased glucose production by the liver.

New perspectives on the use of glucagon-like peptide 1 in diseases of the central nervous system

Current Issues in Pharmacy and Medical Sciences, 2023
Glucagon-like peptide 1 is a neuromodulatory peptide that regulates the carbohydrate metabolism. It can cross the blood-brain barrier, and, indeed, while mostly produced in the distal small intestine and colon, it is also synthesized in the nucleus of ...

Betacellulin-Induced α-Cell Proliferation Is Mediated by ErbB3 and ErbB4, and May Contribute to β-Cell Regeneration

Frontiers in Cell and Developmental Biology, 2021
Betacellulin (BTC), an epidermal growth factor family, is known to promote β-cell regeneration. Recently, pancreatic α-cells have been highlighted as a source of new β-cells. We investigated the effect of BTC on α-cells.
