Abstract
BACKGROUND: Variations of α-synuclein levels have been reported in serum and plasma in Parkinson's Disease (PD) Patients. METHODS: Serum and plasma were obtained from PD patients without known mutations (GU-PD, n = 124)), carriers of the A53T/G209A point mutation in the α-synuclein gene (SNCA) (n = 29), and respective age-/sex-matched controls. Levels of total α-synuclein were assessed using an in-house ELISA assay. RESULTS: A statistically significant increase of α-synuclein levels was found in serum, but not plasma, from GU-PD patients compared to healthy controls. A statistically significant decrease of α-synuclein levels was found in serum and plasma from symptomatic A53T mutation carriers compared to healthy controls. Plasma α-synuclein levels were modestly negatively correlated with UPDRS part III score and disease duration in A53T-PD patients. CONCLUSION: Increased α-synuclein levels in serum of GU-PD patients suggest a systemic deregulation of α-synuclein homeostasis in PD. The opposite results in A53T-PD highlight the complexity of α-synuclein homeostatic regulation in PD, and suggest the possibility of reduced expression of the mutant allele.
