A detailed analysis of DJ-1 and tau localization in brains from patients with mutated forms of DJ-1 would be of major help to clarify their interaction, as the only DJ-1-associated PD case that came to autopsy thus far [17] showed tau neurofibrillary tangles consistent with Braak neurofibrillary stage I/primary age-related tauopathy. The gene discussed is MAPT; the disease is Parkinson disease.
