A 2020 study found NAC improved dopaminergic function in PD patients
Implicated mechanisms include upregulation of molecular pathways involved in oxidative stress, aberrant calcium signaling, silencing of transcription factors and histone deacetylases, and deregulation of cytoskeleton-associated proteins
