Glucagon-like Receptor Agonists

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a significant...

Hormones Regulating Blood Glucose

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Summary

Incretin hormones like GIP and GLP-1 regulate glucose and body weight. Research explores their roles in diabetes, obesity, and cellular health, with therapeutic potential for agonists and antagonists.

Area of Science:

Endocrinology
Gastroenterology
Metabolic Research

Background:

Incretin hormones, secreted post-nutrient ingestion, enhance insulin secretion.
Glucosodependent Insulinotropic Peptide (GIP) and Glucagon-Like Peptides (GLP-1, GLP-2) are key incretins with diverse physiological roles.
Emerging evidence indicates GIP synthesis in pancreatic alpha cells and GLP-1 receptors in the liver.

Purpose of the Study:

To review the multifaceted roles of GIP and GLP-1/GLP-2.
To highlight their therapeutic potential in metabolic diseases like diabetes and obesity.
To discuss their effects beyond glucose homeostasis, including on bone, CNS, and cardioprotection.

Main Methods:

Literature review and synthesis of existing research on incretin hormones.

Examination of recent findings on incretin hormone synthesis and receptor distribution.

Main Results:

GIP influences lipogenesis, lipolysis, bone metabolism, and neuronal function, with therapeutic potential for both agonists (diabetes) and antagonists (obesity).
GLP-1 stimulates insulin, inhibits glucagon, promotes beta-cell health, reduces food intake, and offers cardioprotective effects.
GLP-2 enhances intestinal function, promotes enterocyte proliferation, and reduces bone resorption.

Conclusions:

Incretin hormones represent a significant area for therapeutic development in metabolic and other diseases.
GIP and GLP-1/GLP-2 exhibit broad physiological effects, suggesting diverse clinical applications.
Further research into incretin pathways may unlock novel treatments for conditions ranging from diabetes to obesity and beyond.
