中文摘要：

神经肽Y（NPY）是中枢神经系统内含量最多的神经肽之一,它参与机体多种生理活动。近年来,对不同痛模型中NPY作用的研究表明,NPY可能通过激活脊髓和脊髓上水平的Y1受体或拮抗背根节的Y2受体发挥镇痛作用,此类研究将为NPY及其受体激动剂在镇痛中的应用提供重要的理论基础。本文就NPY及其Y1、Y2受体在痛觉调制中的作用作一简要综述。

英文摘要：

　Neuropeptide Y （ NPY ） is one of the most abundant neuropeptides in the central nervous system （CNS）, which is involved in lots of physiological actions. Recently, there are many articles about NPY targeting its roles in pain modulation by means of different animal models. It is shown that the analgesic effect could be induced by either activating the Y1 receptor locating in the CNS or inhibiting the Y2 receptor in the DRG. These studies would provide important rationale for development and application of new type analgesic drugs aiming directly at Y1/Y2 receptor. This review will summarize the roles of NPY in pain processing and related mechanisms in these researches.
