Abstract

Parkinson's disease (PD) is a neurodegenerative disorder characterized by Lewy pathology and progressive loss of dopaminergic neurons in the substantia nigra. Lewy pathology mainly consists of abnormal aggregates of α-synuclein, which play a pivotal role in PD pathophysiology. However, the complexity of PD leads to clinical challenges, and there are still no treatments to halt or slow the neurodegenerative process. Resveratrol (RV) is a natural polyphenol compound with multiple biological activities, which has been reported to exert neuroprotective effects on several neurological diseases. Here we first provided evidence that RV treatment alleviated motor and cognitive deficits in the A53T α-synuclein mouse model of PD in a dose-dependent manner. The beneficial effects of RV against PD resulted from inhibiting α-synuclein aggregation and cytotoxicity, lowering the levels of total α-synuclein and oligomers, reducing neuroinflammation and oxidative stress. These findings suggest that RV has promising therapeutic potential for PD and other synucleinopathies.
