Potential Mechanisms Behind GLP-1 Effects on Addictive Behaviours Understanding the biological mechanisms through which GLP-1 receptor agonists might influence addictive behaviours requires examining the neuroanatomy of reward processing and how these medications interact with relevant brain circuits
Shared GHS-R1a Pathway Both peptides bind the growth hormone secretagogue receptor 1a, a G-protein-coupled receptor expressed on somatotroph cells in the anterior pituitary and on hypothalamic arcuate nucleus neurons
Given the essential role of GH/IGF-1 in growth and metabolism, any exposure of a newborn to sermorelin via milk is of uncertain significance
While IGF-1 has insulin-agonistic actions and has been used for treatment of severe insulin resistance, IGF-1 reduction with the GH antagonist pegvisomant improves glycemic control in acromegalic patients with diabetes or impaired glucose tolerance despite elevated GH (35, 36)
