研究人员发现了一种关键分子，所有瘙痒受体细胞都需要这种分子实现瘙痒信号所需的脑神经联系。该分子是一种叫做Nppb的小分子神经肽 ——将其去除就不会有瘙痒。研究显示，Nppb是感觉瘙痒的皮肤受体细胞与将瘙痒感知输送至脑部的神经细胞之间的一个必不可少的环节。研究人员在缺乏Nppb分子的小鼠身上成功了进行测试。论文发表在今天出版的《科学》期刊上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
