Abstract
Mammalian cells use hydrogen peroxide (H(2)O(2)) not only to kill invading pathogens, but also as a signaling modulator. Woo et al. (2010) now show that the local inactivation of a H(2)O(2)-degrading enzyme ensures that the production of this oxidant is restricted to the signaling site.
摘要
哺乳动物细胞不仅利用过氧化氢 (H(2)O(2)) 来杀死入侵的病原体，还将其作为一种信号调节剂。Woo 等人（2010 年）现在表明，局部失活一种 H(2)O(2) 降解酶可确保这种氧化剂的产生仅限于信号部位。
