Protective effect of thioredoxin reductase 1 in Parkinson's disease

Parkinson's disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). Many factors can explain the mechanism. However, the precise mechanism that contributes to the decreased number of dopaminergic neurons is unknown. Our study shows that oxidative stress is increased in models of PD compared with WT mice; Thioredoxin reductase 1(TR1) has emerged as an important antioxidant agent in dopaminergic neurons. In summary, our findings demonstrate that the overexpression of TR1 could be developed into a novel neuroprotective strategy for PD and that the reduction of the expression of GSK-3β and NF-κB could also be promising therapeutic strategies for PD. This research suggests a new direction in the treatment of PD.
