中文摘要：
神经肽Y（NeuropeptideY，NPY）家族作为一种神经递质，参与到脊椎动物许多生理功能的调控。神经肽F（NeuropeptideENPF）作为NPY在非脊椎动物中的同源肽，也具有类似的功能，目前NPF已经在许多的昆虫中得到鉴定，它一般由28—45个残基组成，C端为保守的RPRFamide结构。通过与配对的G蛋白偶联受体NPFR（NeuropeptideFreceptor）结合，在昆虫的取食、酒精敏感性、攻击行为、繁殖、时钟节律和学习能力等诸多行为中发挥调节作用，但NPF／NPFR信号通路目前尚不明确。本文概述了NPF及其受体在一些模式动物上的分布及生理功能。
英文摘要：
The neuropeptide Y （NPY） family acts as neurotransmitters and contributes to a diversity of physiological functions in vertebrates. Neuropeptide F （NPF）, the NPY-like ortholog in invertebrates, has been identified in numerous insects and shares some similar functions with NPY. Commonly, NPFs consist of 28-45 residues and have a conserved C-terminal RPRFamide. They play a very important role in feeding, ethanol sensitivity and stress responses, including aggression, reproduction, circadian rhythm, and learning, by interaction with NPFRs, which are a kind of G protein-coupled receptor （GPCR）. However, the NFP/NPFR signaling pathway is not well understood. This paper provides an overview of the distribution and functions of NPFs and their receptors in several model insects.
