Scientific Background | Nitrotyrosine is a post-translational modification formed by the nitration of tyrosine residues, often mediated by reactive nitrogen species such as peroxynitrite. It serves as a biomarker of nitrosative stress and is increasingly recognized for its role in neurodegenerative disease pathology. Nitrotyrosine-modified proteins are frequently detected in Alzheimer’s disease, Parkinson’s disease, and ALS, where they correlate with inflammation-induced tissue injury. Enzymes such as myeloperoxidase, cytochrome P450s, and superoxide dismutase catalyze tyrosine nitration, disrupting protein function and contributing to neuronal damage. As a marker of oxidative and nitrosative stress, nitrotyrosine provides mechanistic insight into redox imbalance and may serve as a diagnostic and therapeutic target in neurodegeneration. |
