WHAT STARTS THE GROWTH HORMONE SIGNAL? Brain → Pituitary → Growth Hormone → IGF-1
🧬 What tells the body to release growth hormone?
Growth hormone is part of a communication system connecting the brain, pituitary gland and other tissues.
Here is the simple version:
🧠 The brain sends a message called GHRH.
🔬 The pituitary gland receives that message and releases growth hormone.
🧬 Growth hormone then sends signals to different tissues.
⚙️ Some of those signals lead to the production of IGF-1, which works farther down the pathway.
Growth hormone-related research compounds do not all work at the same point in this system.
Some are studied for copying the original GHRH message. Others activate the ghrelin receptor, which provides another signal connected with growth hormone release. IGF-1 LR3 is studied farther down the pathway.
Understanding where a compound fits helps researchers choose the material that matches their research question.
Different compound. Different signal. Different research question.
