Alterations in the redox status of proteins have been implicated in the pathology of several neurodegenerative conditions including Alzheimer and Parkinson diseases. We report that peroxynitrite- and hydrogen peroxide-induced disulfides in the neuron-specific microtubule-associated proteins tau and microtubule-associated protein-2 are
