What is the Origin of GHS-R Sensitivity?

The term originates from the discovery of the GHS-R in the neuroendocrine system and the subsequent identification of ghrelin as its natural ligand. Research into the pharmacological properties of synthetic Growth Hormone Secretagogues (GHSs) led to the clinical understanding of how receptor affinity and density dictate the efficacy of these compounds. This knowledge is foundational to understanding somatotropic axis regulation.

What is the Mechanism of GHS-R Sensitivity?

Sensitivity is determined by the conformational state and density of the GHS-R on the cell membrane. High sensitivity means a lower concentration of ghrelin or a secretagogue is required to activate the receptor, triggering the release of GH from the pituitary. Desensitization, often occurring with chronic, high-dose stimulation, involves receptor internalization or uncoupling from its intracellular signaling proteins. The therapeutic aim is often to maintain or restore high GHS-R sensitivity to maximize the physiological release of GH.

GHS-R Sensitivity

Meaning

GHS-R Sensitivity refers to the degree of responsiveness of the Growth Hormone Secretagogue Receptor (GHS-R), also known as the ghrelin receptor, to its primary endogenous ligand, ghrelin, or to exogenous secretagogues. The GHS-R is predominantly located in the hypothalamus and pituitary gland, playing a central role in regulating appetite, energy balance, and the pulsatile release of Growth Hormone (GH). Optimizing this sensitivity is key to supporting metabolic and anabolic functions.
