Parkinson's: New study associates oxidative stress with the spreading of aberrant proteins

Researchers at DZNE associate oxidative stress with the spreading of abnormal alpha-synuclein protein in Parkinson's disease, a neurodegenerative disorder. The findings suggest that oxidative stress may trigger the formation and aggregation of toxic alpha-synuclein species, leading to progressive pathology and neuronal damage.
