Model of NPY signaling for the regulation of bone formation. Neuropeptide Y signals in the hypothalamus via Y2 receptors inhibit the function of osteoblasts. Y1 receptors expressed on osteoblasts also inhibit osteoblast activity. The local role of osteoblastic NPY, which is inhibited by mechanical loading, is yet to be determined.
