What is the Origin of Neuropeptide Y?

The name "Neuropeptide Y" is derived from its structure: it is a peptide found in neural tissue (Neuro-peptide), and the single-letter abbreviation for the amino acid tyrosine, which is present at the C-terminus, is 'Y'. It was first isolated in the early 1980s, identifying a novel class of regulatory peptides critical to central nervous system function.

What is the Mechanism of Neuropeptide Y?

NPY primarily exerts its effects by binding to a family of G-protein coupled receptors, specifically Y1, Y2, Y4, Y5, and Y6 receptors, expressed on various neuronal and peripheral cells. In the hypothalamus, NPY drives the sensation of hunger (orexigenic effect) and promotes fat storage, serving as a critical component of the body's energy homeostasis mechanism. Furthermore, its release in response to stress helps mitigate the physiological impact of chronic anxiety.

Neuropeptide Y

Meaning

Neuropeptide Y (NPY) is a 36-amino acid peptide neurotransmitter and neuromodulator widely distributed throughout the central and peripheral nervous systems. Clinically, it is recognized for its potent effects on appetite stimulation, energy balance, anxiety reduction, and the physiological response to stress. Its activity is closely linked to metabolic health and the hypothalamic regulation of feeding behavior.
