What is the Origin of Glucagon-Like Peptide?

The name is derived from its structural similarity to glucagon, another peptide hormone produced by the pancreas, combined with its intestinal origin ("Like Peptide"). Incretin refers to gut-derived substances that potentiate glucose-dependent insulin secretion. This discovery refined our understanding of gut-brain-pancreas axis communication.

What is the Mechanism of Glucagon-Like Peptide?

GLP-1 acts via the GLP-1 receptor (GLP-1R) on pancreatic beta cells in a glucose-dependent manner, enhancing insulin secretion and promoting beta-cell survival. Additionally, it slows gastric emptying and increases satiety signals to the central nervous system, which modulates appetite regulation. This multi-target action positions GLP as a critical link between nutrient intake and systemic metabolic control.

Glucagon-Like Peptide

Meaning

Glucagon-Like Peptide (GLP) refers to a group of incretin hormones, primarily GLP-1 and GLP-2, secreted by enteroendocrine L-cells in the intestine in response to nutrient ingestion. GLP-1 plays a pivotal role in glucose homeostasis by stimulating insulin release and inhibiting glucagon secretion, thereby managing postprandial blood sugar excursions. These peptides are fundamental regulators of metabolic signaling post-meal.

A tightly woven network of light strands features a central, spiky spherical element. This represents the endocrine system's intricate hormonal pathways and cellular signaling. It illustrates how bioidentical hormones or peptide protocols achieve receptor binding and homeostasis, crucial for metabolic optimization and clinical wellness in Hormone Replacement Therapy.
