摘要:
背景: 韩国雷德·雷德·辛格(Suberean Red red)panax ginax ginseng erseyer takyed panax meyer-a spaneg a panax meyer-has长期用作传统药物。最近发现了其抗尿素作用,但没有揭示其分子机制。因此,当前的研究重点是确定朝鲜红人人参提取物(RGE)AGAI的基本分子机制nst histamine-induced itch at the peripheral sensory neuronal level.
METHODS: To examine the antipruritic effect of RGE, we performed in vivo scratching behavior test in mice, as well as in vitro calcium imaging and whole-cell patch clamp experiments to elucidate underlying分子机制。
结果: 我们的体内研究结果证实,RGE确实对小鼠中组织胺诱导的抓挠具有抗尿素作用。此外,RGE对小鼠背根神经节原发性培养物的组胺诱导反应产生了显着抑制作用,这表明RGE对感觉神经元水平具有直接的抑制作用。进一步实验的结果表明,RGE抑制组胺诱导的对表达组胺受体亚型1和TRPV1离子通道的细胞的反应,表明RGE阻止了组胺受体受体1/TRPV1途径sensory neurons, which is responsible for histamine-dependent itch sensation.
CONCLUSION: The current study found for the first time that RGE effectively blocks histamine-induced itch in peripheral sensory neurons.我们认为,当前的结果将提供有关瘙痒传播的见解,并将有助于理解RGE如何发挥其抗精性效应。
