Scientific background

Neuropeptide Y (NPY) is a 36 amino acid peptide neurotransmitter present in the central and peripheral nervous systems.1 NPY is involved in the regulation of a broad range of functions such as eating behavior, hypertension, and reproduction.2

NPY exerts its effects via five receptor subtypes known as the neuropeptide Y receptors (NPYR): Y1 (NPY1R), Y2 (NPY2R), Y4 (NPY4R), Y5 (NPY5R), and Y6 (NPY6R).2 Four of these (Y1, Y2, Y4, and Y5) are expressed in humans.2 The NPY receptors belong to the G protein-coupled receptor superfamily whose members share a common structure of seven putative transmembrane domains, an extracellular amino terminus, and a cytoplasmic carboxyl terminus.

Activation of these receptors by NPY affects [Ca2+]i, adenylate cyclase signalling, and a number of ion channel functions.Based on their high frequency and density in steroid hormone-producing tumors, the NPYRs might be of potential use in tumor management.2

NPY5R as well as NPY1R and NPY2R are expressed in the hypothalamus, in the brain stem, and in peripheral tissues, such as blood vessels, lung, kidney, adrenal glands, stomach, colon, heart, pancreas, and intestine. NPY5R has been postulated as the mediator of the feeding response to NPY and related peptides (125 in Kamiji, M. M). Its localization in the brain is consistent with this hypothesis.4
