Longitudinal Study of Salivary Biomarkers in the Definition of Clinico‐Molecular Progression of Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Longitudinal changes in salivary biomarkers in Parkinson’s disease (PD) from early (T0) to 4‐year follow‐up (T1), quantified by ELISA: oligomeric and total α‐synuclein, total and phosphorylated tau, MAP1LC3B (autophagy), and TNFa (inflammation). Blue arrows indicate direction of change at T1 vs T0 (up = increase; down = decrease).
