Modification to the disulfide bridge between cysteines 9 and 50 had only a modest effect on IL-8 function. 33 The role of oxidants in the regulation of IL-8 and other chemokines has relevance in the field of cardiovascular disease, where ischaemia-induced oxidative stress is both a marker of disease and a potential therapeutic target. STUDY. Background and purpose: Lung epithelial cells express pattern recognition receptors, which react to bacteria. Your doctor may order additional tests such as joint fluid test, cerebrospinal test to confirm his diagnosis. These cytokines also play an important role in immune cell differentiation and activation.
