It plays a crucial role in cellular events such as inflammatory responses, altered cell growth, and apoptosis ( Figure 1 ) ( Figure 1 The role of alterations in the antioxidant system in the pathogenesis of vitiligo has been extensively studied ( CAT gene and reduced catalase activity have also been associated with several metabolic diseases, such as diabetes, hypertension, and peroxisomal/peroxisomal diseases ( On the other hand, the chronic OS will produce an excessive accumulation of ROS, which in turn induces the production of damage-associated molecular patterns (DAMPs) and the release of melanosomal antigens that activate innate immunity ( + T cells are activated through HSP70i activation and antigen presentation by mature dendritic cells ( + T cells are recruited to induce melanocyte apoptosis ( + T cells ( These findings suggest that oxidative stress plays a vital role in the pathogenesis of vitiligo
