What Does NPY Stand For?

NPY stands for Neuropeptide Y

Neuropeptide Y (NPY) is a 36-amino acid peptide involved in various physiological processes, including the regulation of appetite, circadian rhythms, and stress response. It functions primarily within the central nervous system and the peripheral nervous system, acting as a neurotransmitter and neuromodulator. NPY plays a crucial role in energy balance and influences behaviors related to feeding and anxiety. Dysregulation of NPY signaling has been implicated in metabolic disorders and mood disorders, making it a significant focus of research in neurobiology and endocrinology.
