是什么引发瘙痒?科学家们“抓住”一个新的罪魁祸首
If you've got itchy skin, it could be that a microbe making its home on your body has produced a little chemical that's directly acting on your skin's nerve cells and triggering the urge to scratch.That's the implication of
some new research that shows how a certain bacteria,Staphylococcus aureus.can release an enzyme that generates an itchy feeling. What's more, a drug that interferes with this effect can stop the itch in laboratory mice. according to a new report in the journal Ceil.
如果你的皮肤瘙痒，可能是在你身上安家的微生物产生了一点化学物质，直接作用于你的皮肤神经细胞，引发了抓挠的冲动。
新研究表明一种特定细菌，也就是金黄色葡萄球菌，能释放一种酶，从而产生瘙痒感。
更重要的是，根据《细胞》杂志上的一份新报道，一种能干扰这种作用的药物能让实验鼠停止瘙痒。
