Galanin-like peptide

Galanin-like peptide (GALP) is a neuropeptide present in humans and other mammals. It is a 60-amino acid polypeptide produced in the arcuate nucleus of the hypothalamus and the posterior pituitary gland.^[1][2][3] It is involved in the regulation of appetite and may also have other roles such as in inflammation, sex behavior, and stress.^{[4][5][6][7][8][9]}

Findings additionally suggest that GALP could play a function in energy metabolism due to its ability to maintain continual activation of the sympathetic nervous system (SNS) via thermogenesis, which refers to the production of heat within living organisms.^[10] In addition, the administration of GALP directly into the brain leads to a reduction in the secretion of thyroid-stimulating hormone (TSH), which indicates the involvement of GALP in the neuroendocrine regulation of the hypothalamic-pituitary-thyroid (HPT) axis, and further adding to the evidence of the role of GALP in energy homeostasis.^[11]
