Dual Role of Hydrogen Peroxide As an Oxidant in Pneumococcal Pneumonia.

abstract：:Oxidative stresses are largely mediated by intracellular protein oxidations by reactive oxygen species (ROS). Host cells are equipped with antioxidants that scavenge ROS. The cellular reduction/oxidation (redox) balance is maintained by ROS and antioxidants. Accumulating evidence suggests that the redox balance plays ...
