Parkinson's disease (PD) is a general neurodegenerative disorder which largely has an effect on the society of the aged populations. PD is distinguishedwith loss of dopaminergic (DA) neurons in the substantia nigra. The exceptional properties of gold nanoparticles (AuNPs) have fascinated great attention in biomedical applications. In this present study, we explored theprospective beneficial effects of AuNPs synthesized from Cinnamomum verum on PD. PD rat models were established through MPTP injection treatment and AuNPs was administered. Administration of AuNPs reduces effect of MPTP-induced oxidative stress and motor abnormalities observed in PD rats. In addition ELISA analysis demonstrated that AuNPs treatment significantly attenuates Tumor Necrosis Factor-alpha (TNF-alpha), Interleukin-1 beta (IL-1 beta) and Interleukin-6 (IL-6) expression levels. Consequently, we investigated TLR/NF-kappa B pathway to examine the function of AuNPs on MPTP- induced PD rats. We found that AuNPs suppressed the alterations in the pathway of TLR/NF-kappa B associated molecules in MPTP stimulated PD rats. Hence, our results suggest that AuNPs attenuates MPTP introduced motor disorders, oxidative stress, activated inflammatory cytokines and activated TLRINF-kappa B signaling in PD rats. In conclusion, AuNPs ease PD symptoms by the inhibition of TLR/NF-kappa B signaling pathway and recommend promise approach in the treatment of neurodegenerative diseases such as PD.
