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。
