Inflammation activates a variety of inflammatory cells, which induce and activate several oxidant-generating enzymes which are able to produce high concentrations of free radicals and oxidants which react with each other to generate other more potent reactive oxygen and nitrogen species such as peroxynitrite (ONOO−) that can damage DNA, RNA, lipids, and proteins by nitration, oxidation, etc., leading to increased mutations and altered functions of enzymes and ...
