Where this comes from

Abstract

Neuropeptide Y (NPY) is a powerful orexigenic factor in the brain. However, mice lacking NPY or NPY receptor Y1 (NPY1R) have minimal changes in basal food intake. In a study published in Nature, Zhu et al.<sup>1</sup> demystify this paradox and show that central and peripheral NPY have antipodal roles in energy homeostasis.
