Somatotroph Activation

Meaning

Somatotroph activation refers to the stimulation of somatotroph cells, located in the anterior pituitary gland, to synthesize and secrete Growth Hormone (GH). This process is a crucial part of the Hypothalamic-Pituitary-Somatotropic (HPS) axis and is essential for promoting growth, cellular repair, and metabolic regulation. Clinical strategies for somatotroph activation often involve the use of Growth Hormone-Releasing Hormone (GHRH) analogues or Growth Hormone Secretagogues (GHS) to enhance the natural, pulsatile release of GH. Optimizing this activation is a core goal in addressing age-related decline in body composition and vitality.
