What is the Origin of GIP Receptors?

The name is derived from the acronym GIP, which stands for the hormone they bind, Glucose-dependent Insulinotropic Polypeptide. The term "receptor" stems from the Latin recipere (to receive). The concept of GIPR is deeply rooted in the study of gastrointestinal hormones and their powerful regulatory role in post-prandial glucose homeostasis, establishing a key link between the gut and the endocrine pancreas.

What is the Mechanism of GIP Receptors?

The binding of GIP to the GIPR on the beta cell membrane initiates an intracellular signaling cascade involving the activation of adenylate cyclase, leading to an increase in cyclic AMP (cAMP). This rise in cAMP potentiates the cell's response to glucose, enhancing the exocytosis of insulin-containing granules. This mechanism ensures a rapid and robust insulin secretion that is tightly coupled to the circulating glucose concentration after a meal.

GIP Receptors

Meaning

GIP Receptors, or Glucose-dependent Insulinotropic Polypeptide Receptors (GIPR), are G protein-coupled receptors expressed primarily on the surface of pancreatic beta cells, as well as in adipose tissue and the brain. These receptors bind to the incretin hormone GIP, which is secreted by intestinal K cells following nutrient ingestion. Activation of GIPR is a fundamental component of the enteroinsular axis, significantly amplifying the glucose-stimulated release of insulin.
