Oxidative stress and altered immune function: The correlation between and immune function of the body is beyond doubts. The skilled phagocytic cells (macrophages, neutrophils, eosinophils) possess an enzyme, the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (; ); which is responsible for the production of ROS following an immune challenge. The host defense mechanism uses the lethal effects of ROS and RNS in the killing pathogens. At the commencement of an , phagocytes increase their oxygen demand by 10-20 folds via., process of respiratory burst. The nascent oxygen generated by this enzyme serves as the starting material for the production of an array of reactive species. Production of other powerful pro-oxidants, such as (H2O2), hypochlorous acid (HOCl), peroxynitrite (ONOO¯) and possibly hydroxyl (OH●) and ozone (O3) by these cells have also been reported. Although, these highly reactive endogenous metabolites damage all the the bacterial cells non-specifically, they can also injure the host tissues (). Cashewnut, () is an antioxidant and is used in indigenous system for immunomodulation purposes (; ; , ).
