Oxidative agents are generated in large amounts during inflammation. These highly reactive intermediates interact with several extracellular and intracellular molecules and with each other, thus generating a complex network of responses culminating in an outcome that may be detrimental or beneficial for the host. Alongside with the well known systems involved in production of reactive oxygen species or reactive nitrogen species, such as the NADPH oxidase or the nitric oxide synthase, novel enzymatic pathways have been discovered. This has unveiled new targets and functions for oxidant species, and has prompted the development of innovative anti-inflammatory drugs. In the new integrate scenario stemming from these studies oxidant species are increasingly recognized as true messengers, and even their toxic effects are viewed as the result of the perversion of an otherwise physiological extra / intra cellular signaling.

Keywords: inflammation, reactive oxygen species, reactive nitrogen species, protein tyrosine phosphatases, nadph oxidase, no-aspirin
