Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH), consisting of the full 44-amino acid sequence of endogenous GHRH with a trans-3-hexenoic acid group attached to stabilize the molecule. It acts on the anterior pituitary gland to stimulate the pulsatile release of endogenous growth hormone.
Mechanism of Action
Tesamorelin binds to GHRH receptors on somatotroph cells in the anterior pituitary. This binding triggers intracellular signaling cascades that result in the synthesis and secretion of growth hormone. Unlike exogenous growth hormone administration, Tesamorelin preserves the natural pulsatile release pattern of GH secretion.
Research Context
Tesamorelin has been investigated in research settings for its effects on growth hormone secretion, lipid metabolism, and body composition. Laboratory studies have examined its interactions with the hypothalamic-pituitary axis and downstream IGF-1 pathways.
