    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neuropeptide Y; Receptor; Evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Abstract : The three evolutionarily related peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP) are ligands to at least five G-protein coupled receptors in mammals, which are denoted by numbers. NPY has many physiological effects including stimulation of appetite and regulation of circadian rhythm and blood pressure. READ MORE
