Introduction: Substance P (SP) is a member of the tachykinin family. In the central nervous system, SP participates among others, in the regulation of pain, learning, memory, emotion, and sexual functions. In the periphery, SP affects the gastrointestinal, cardiovascular, and urinary systems. Galanin, similarly to SP, appears to be involved in wide range of physiologic functions, including cognition, waking and sleep, feeding, mood, blood pressure, reproduction, and development, where acts as a trophic factor. The similar distribution of SP-immunoreactive (SP-IR) fibers and galanin-IR perikarya in the human hypothalamus suggests functional interaction between these neuropeptides.

物质 P 免疫反应性纤维静脉曲张似乎可以支配人类下丘脑中的甘丙醇 Perikarya

简介：物质 P (SP) 是速激肽家族的成员。在中枢神经系统中，SP 参与调节疼痛、学习、记忆、情绪和性功能等。在外周，SP 影响胃肠道、心血管和泌尿系统。甘丙肽与 SP 类似，似乎涉及广泛的生理功能，包括认知、清醒和睡眠、喂养、情绪、血压、繁殖和发育，其中充当营养因子。人下丘脑中 SP 免疫反应性 (SP-IR) 纤维和甘丙肽-IR perikarya 的相似分布表明这些神经肽之间存在功能相互作用。
