Table of Contents Toggle The Brain’s Most Abundant Neuropeptide Research Tools and Receptor Pharmacology The Brain’s Most Abundant Neuropeptide Neuropeptide Y (NPY) is a 36-amino-acid peptide that holds a remarkable distinction: it is the most abundant neuropeptide in the mammalian central nervous system. First isolated from porcine brain in 1982 by Kaare Tatemoto, NPY belongs […]
Table of Contents Toggle Structural Features and Stability Open Research Questions Alpha-melanocyte-stimulating hormone (α-MSH) is a 13-amino-acid peptide derived from the post-translational processing of proopiomelanocortin (POMC) in the anterior pituitary, hypothalamus, and various peripheral tissues. But that is barely the opening act. The melanocortin system comprises five receptor subtypes (MC1R through MC5R), and α-MSH activates […]
