Background Information

Neuropeptide Y (NPY) is one of the most abundant peptides in the mammalian central nervous system (CNS). NPY has been linked to several physiological and pathological functions, such as feeding behaviour, memory processing, pain, anxiety, cell proliferation and many other processes in the central and peripheral nervous systems. The neuropeptide functions through G protein-coupled receptors to inhibit adenylyl cyclase, activate mitogen-activated protein kinase (MAPK), regulate intracellular calcium levels, and activate potassium channels. In addition, NPY was suggested as a potential neuroprotective agent in Alzheimer's disease by counteracting the toxic effect of β-amyloid in an in vitro model.
