neuropeptide

[‚nu̇r·ō′pep‚tīd]

(neuroscience)

A polypeptide released by axons at the synapse; it may act as a neurotransmitter and have a direct effect on synapse function or as a neuromodulator, having a long-term effect on postsynaptic neurons.

The neuropeptides concerned with feeding behavior are involved in this complex controlling system, of which the anorexigenic neuropeptide like proopiomelanocortin (POMC) and orexigenic neuropeptide like Neuropeptide Y (NPY) play important roles in the regulation of food intake and energy balance (Bazhan and Zelena, 2013).
