What is the Origin of GHSR Agonists?

The term is a concise abbreviation of Growth Hormone Secretagogue Receptor Agonists, with agonist derived from the Greek agōnistēs meaning "actor," signifying a molecule that initiates a full physiological response upon binding to its receptor. This nomenclature accurately reflects their direct and stimulatory action on the somatotropic axis.

What is the Mechanism of GHSR Agonists?

By binding to the GHSR, which is a G-protein coupled receptor, these agonists trigger a specific intracellular signaling cascade, prominently involving the mobilization of calcium ions within the somatotroph cells. This robust signaling mechanism leads to a pronounced, pulsatile increase in the synthesis and subsequent release of growth hormone into the systemic circulation. The resulting elevation in growth hormone levels then influences downstream anabolic and metabolic processes, largely mediated by Insulin-like Growth Factor 1.

GHSR Agonists

Meaning

GHSR agonists are a specific class of pharmacological compounds engineered to selectively bind to and activate the Growth Hormone Secretagogue Receptor, which is also recognized as the ghrelin receptor. These agents effectively mimic the action of the endogenous hormone ghrelin, powerfully stimulating the release of growth hormone from the anterior pituitary gland. They are currently under clinical investigation for therapeutic applications related to treating growth hormone deficiency, sarcopenia, and certain forms of metabolic dysregulation.
