Abstract: Parkinson's disease (PD) is a common neurodegenerative disorder which affects dopaminergic neurons leading to alteration of numerous cellular pathways. Several reports highlight that PD disturbs also other cells than CNS neurons including PBMCs, which could lead, among other things, to dysfunctions of immune functions. Because autophagy could be altered in PD, a monocentric pilot study was performed to quantify the transcripts levels of several autophagy genes in blood cells. MAP1LC3B, GABARAP, GABARAPL1, GABARAPL2 and P62/SQSTM1 were found to be overexpressed in patients. On the contrary, transcripts for HSPA8 and GAPDH were both decreased. Expression of MAP1LC3B and GABARAP was able to successfully segregate PD patients from healthy controls. The accuracy of this segregation was substantially increased when combined expressions of MAP1LC3B and GAPDH or GABARAP and GAPDH were used as categorical variables. This pilot study suggests that autophagy genes expression is dysregulated in PD patients and may open new perspectives for the characterisation of prediction markers.
