Glucagon-like peptide-1 (GLP-1), an insulinotropic gastrointestinal peptide that is primarily produced by intestinal endocrine L-cells, stimulates satiety. Ghrelin, a hormone that is produced predominantly by the stomach stimulates hunger. There are two forms of ghrelin: active ghrelin and inactive des-acyl ghrelin. After depriving mice of food for 24 h, we demonstrated that the systemic admini...
Glucagon-like peptide-1 (GLP-1) is both a peripherally expressed incretin and a centrally active neuropeptide. Brain derived GLP-1, produced in preproglucagon (PPG) neurons located in the nucleus of the solitary tract (NTS) and projecting to numerous brain regions, is ideally placed to activate central GLP-1 receptors in a range of autonomic control areas. In vivo analysis of central GLP-1 usin...
Cyclic constraints are incorporated into an 11-residue analogue of the N-terminus of glucagon-like peptide-1 (GLP-1) to investigate effects of structure on agonist activity. Cyclization through linking side chains of residues 2 and 5 or 5 and 9 produced agonists at nM concentrations in a cAMP assay. 2D NMR and CD spectra revealed an N-terminal β-turn and a C-terminal helix that differentially i...
Nine female runners and ten walkers completed a 60 min moderate-intensity (70% VO(2)max) run or walk, or 60 min rest in counterbalanced order. Plasma concentrations of the orexogenic peptide ghrelin, anorexogenic peptides peptide YY (PYY), glucagon-like peptide-1 (GLP-1), and appetite ratings were measured at 30 min interval for 120 min, followed by a free-choice meal. Both orexogenic and anore...
Both Epac and PKA are effectors of the second messenger cAMP. Utilizing an exchange protein directly activated by cAMP (Epac) pathway-specific cAMP analog (ESCA), we previously reported that Epac signaling regulates proglucagon gene (gcg) expression in the glucagon-like peptide-1 (GLP-1)-producing intestinal endocrine L-cell lines GLUTag and STC-1. We now show that Epac-2 is also expressed in g...
Glucagon-like peptide 1 (GLP-1) is a hormone released from enteroendocrine L cells. Although first described as a glucoregulatory incretin hormone, GLP-1 also suppresses inflammation and promotes mucosal integrity. Here, we demonstrate that plasma GLP-1 levels are rapidly increased by lipopolysaccharide (LPS) administration in mice via a Toll-like receptor 4 (TLR4)-dependent mechanism. Experime...
This brief review describes the potential non-glycaemic effects and benefits of glucagon like peptide 1 receptor agonists (GLP1RA). It lists various indications in which this class of drugs has been used, and explains the rationale behind this use. The potential uses of GLP1RA extend across the entire spectrum of endocrinology and metabolism, from hypothalamic obesity to non-alcoholic steatohep...
Glucagon-like peptide-1 (GLP-1) is a multifunctional hormone with broad pharmacological potential to control inflammation, protect cardiovascular, kidney, and liver functions. Moreover, GLP-1 can also cross the blood-brain barrier bind GLP-1R distributed in various parts of brain, thereby reducing apoptosis caused by neuroinflammation oxygen stress, promoting learning, memory, cognitive functio...
BACKGROUND Insulinomas are rare tumors, in the majority of cases best treated by surgical resection. Preoperative localization of insulinoma is challenging. The more precise the preoperative localization the less invasive and safer is the resection. The purpose of the study is to check the impact of a new technique to localize insulinoma on the surgical strategy. FINDINGS We present exact pre...
This review analyses a recent advance in diabetes pharmacotherapeutics: the combination of insulin and glucagon-like peptide 1 receptor agonists (GLP 1 RA). It describes the rationale for such a combination, and discusses the impact of such therapy on glycaemic control. The paper also assesses other benefits of the combination, and provides a practical framework for pragmatic, rational use of t...
