What is the Origin of Sermorelin IGF-1 Pathway?

The pathway is named after the synthetic peptide Sermorelin and the primary effector molecule, IGF-1. It is a clinically utilized segment of the natural hypothalamic-pituitary-somatotropic axis.

What is the Mechanism of Sermorelin IGF-1 Pathway?

Sermorelin acts directly on the somatotroph cells of the anterior pituitary gland, binding to GHRH receptors and stimulating the pulsatile release of stored GH. The released GH travels to the liver, where it triggers the synthesis and secretion of IGF-1. IGF-1 then acts systemically on target tissues, binding to its own receptor to promote cell proliferation, differentiation, and protein synthesis, driving tissue growth and repair.

Sermorelin IGF-1 Pathway

Meaning

The specific neuroendocrine cascade initiated by the peptide Sermorelin, a Growth Hormone-Releasing Hormone (GHRH) analogue, which stimulates the pituitary gland to release endogenous growth hormone (GH). The subsequent rise in circulating GH leads to increased hepatic production of Insulin-like Growth Factor-1 (IGF-1), which mediates many of the anabolic and regenerative effects. This pathway is a therapeutic target for optimizing body composition and cellular repair.
