Abstract

Brief applications of a high-K+ solution were used to evoke transient constrictions of arterioles from the guinea-pig small intestine. Analogues of neuropeptide Y (NPY) selective for Y2-receptors reduced the constrictions, whereas NPY or a Y1-selective analogue potentiated the constrictions. We conclude that arteriolar smooth muscle has both Y1 and Y2 receptors, and suggest that Y2 receptors inhibit vasoconstriction by modulating the opening of voltage-sensitive Ca2+ channels. This may be related to the role of NPY that is present in some vasodilator nerves.

摘要

使用高钾溶液的短暂应用来诱发豚鼠小肠小动脉的短暂收缩。对Y2受体具有选择性的神经肽Y（NPY）类似物可减轻收缩，而NPY或Y1选择性类似物则增强收缩。我们得出结论，小动脉平滑肌同时具有Y1和Y2受体，并表明Y2受体通过调节电压敏感性Ca2+通道的开放来抑制血管收缩。这可能与某些血管舒张神经中存在的NPY的作用有关。
