Blood Plasma of Patients with Parkinson’s Disease Increases Alpha-Synuclein Aggregation and Neurotoxicity

Figure 8

Correlation between viability of neurons treated with PD plasma and age, gender, H & Y staging scores, and PD subtype. (a) and (b) PD patients were aged 44 to 85 years, with an average age of 56.68 + 11.42 years. Viability of neurons treated with α-syn and PD plasma was not related to age. (a) , . (b) , . (c) The gender ratio of PD patient and NS groups was 19 : 9 (male : female). Statistical results showed that viability of neurons treated with α-syn and PD plasma was not related to gender. , . (d) Correlation between H & Y score and viability of neurons treated with plasma in the o-α-Syn-PD group. Cell viability decreased with increasing of H & Y score of patients. H & Y: Hoehn & Yahr. , .
