RESUMO
OBJECTIVE: This research has showed that exosomal miRNAs from cerebrospinal fluid could act as biomarkers for Parkinson's disease (PD). However, no analysis has been conducted to explore the potential value of exosomal miRNAs from plasma. PATIENTS AND METHODS: 52 patients with PD were included in study group. 48 healthy adults were included in control group. Blood samples were collected from all those people and then exosomes were extracted from the plasma. RESULTS: Compared with controls, patients with PD showed a significantly higher expression of circulating exosomal miR-331-5p. ROC curve showed that the area values under the curve of miR-331-5p and miR-505 were 0.849 and 0.898, respectively. CONCLUSIONS: Exosomal miRNAs, including miR-331-5p and miR-505, could potentially act as biomarkers for PD.
