1 month ago - The glucagon-like peptide-1 receptor (GLP1R) is a G protein-coupled receptor (GPCR) found on beta cells of the pancreas and on neurons of the brain. It is involved in the control of blood sugar level by enhancing insulin secretion.
Background Glucagon-like peptide-1 receptor agonists are used increasingly in the management of patients living with type 2 diabetes mellitus and obesity. In patients using glucagon-like peptide-1 r...
- GLP-1 and glucose-dependent insulinotropic polypeptide (GIP), both incretin hormones inactivated by dipeptidyl peptidase-4 (DPP-4), stimulate insulin secretion after an oral glucose load via the incretin effect.[16][17] In T2DM, this process can become blunted or absent; however, pharmacological levels of GLP-1 can revive insulin excretion. The benefits of this therapy to treat T2DM include delayed gastric emptying and inhibiting glucagon production from pancreatic -cells if blood sugar levels are high. Furthermore, GLP-1 receptor agonists can decrease pancreatic -cell apoptosis while promoting their proliferation.[18][19][20]
Such details provide a deeper understanding and appreciation for Estimation-Document-Glucagon-Like-Peptide-1-Receptors.
As will be apparent from the above, measurement in plasma of the products of proglucagon gene expression will require assays for at least eight different peptides, three from the pancreas (glucagon, GRPP, major proglucagon fragment) and five from the intestine (glicentin, oxyntomodulin, GLP-1, GLP-2, and intervening peptide 2). For estimation of the secretory state of the alpha or L-cells, it might be proposed to measure just a single proglucagon product, because studies involving isolated perfused preparations of the pancreas or the ileum have shown that the pancreatic and intestinal products, respectively, are secreted synchronously and in equimolar amounts.
This particular example perfectly highlights why Estimation-Document-Glucagon-Like-Peptide-1-Receptors is so captivating.
The glucagon and GLP-1 receptors belong to family B of the seven transmembrane (7TM) G-protein coupled receptors. Family B includes receptors for related peptide hormones, such as glucagon-like peptide-2 (GLP-2), glucose-dependent insulinotropic polypeptide (GIP), vasoactive intestinal polypeptide (VIP), pituitary adenylate cyclase activating polypeptide (PACAP), growth hormone-releasing hormone (GHRH) and secretin.
