1 METHODS: Tyrosinase was modified by reactive-oxygen-species (ROS). Reactive Oxygen Species tyrosinase Homo sapiens
2 METHODS: Tyrosinase was modified by reactive-oxygen-species (ROS). Reactive Oxygen Species tyrosinase Homo sapiens
3 Binding characteristics of antibodies in vitiligo patients (n=25) with varying disease duration (DD) and disease severity were screened against ROS-modified tyrosinase (ROS-tyrosinase) by immunoassays and their results were compared with healthy controls (n=23). Reactive Oxygen Species tyrosinase Homo sapiens
4 RESULTS: The ROS caused extensive alterations in conformation and function of tyrosinase. Reactive Oxygen Species tyrosinase Homo sapiens
5 Interestingly, not only was there an increased number of subjects positive for anti-ROS-tyrosinase-IgGs, but also the levels of these IgGs were significantly higher among vitiligo patients, whose DD were >=10 years as compared to patients with short DD (<10 years). Reactive Oxygen Species tyrosinase Homo sapiens
6 In addition, a significant correlation was observed between the levels of anti-ROS-tyrosinase-IgGs and the patients" ages or with disease severity. Reactive Oxygen Species tyrosinase Homo sapiens
7 Experimentally induced anti-ROS-tyrosinase-IgGs show reactivity with tyrosinase from vitiligo patients. Reactive Oxygen Species tyrosinase Homo sapiens
8 Experimentally induced anti-ROS-tyrosinase-IgGs show reactivity with tyrosinase from vitiligo patients. Reactive Oxygen Species tyrosinase Homo sapiens
