What is that?
Apart from the damage it can cause, oxidative stress can also play an important role in the functioning of organisms, especially in the immune response and inflammation processes. An example is the respiratory burst, the intended production of free radicals from cells belonging to the immune system, like neutrophils and monocytes, when getting in contact with pathogens. The reactive oxygen and nitrogen species yielded from this process, help in the digestion of the leftover particles of bacteria and fungi that have been phagocyted. Impairment in the functioning of the respiratory burst causes high infection rates or tissue damage and leads to clinical complications.
