Antioxidants function as blockers of radical processes and eliminate harmful reactive oxygen species (ROS) produced during normal cellular metabolism. A complex antioxidant defence system has evolved to protect the cellular homeostasis. This system includes antioxidant enzymes (AOEs), such as superoxide dismutases (SODs), which are intracellular MnSOD and CuZnSOD and extracellular ECSOD, H2O2 s...

MCs (mast cells) are critical components of the host innate immune defence against bacterial pathogens, providing a variety of intra- and extra-cellular antimicrobial functions. In the present study we show, for the first time, that the transcriptional regulator HIF-1α (hypoxia-inducible factor-1α) mediates the extracellular antimicrobial activity of human and murine MCs by increasing the forma...
