MPTP-induced neuroinflammation increases the expression of pro-inflammatory cytokines and their receptors in mouse brain.

Abstract

Parkinson's disease (PD) is a common neurodegenerative disease characterised by a slow and progressive degeneration of dopaminergic neurons in the substantia nigra (SN). Despite intensive research, the cause of neuronal loss in PD is poorly understood. Inflammatory mechanisms have been implicated in the pathophysiology of PD. In this study, conducted on an experimental 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model, we investigated the expression of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-6 and their receptors (IL-1RI, TNF-αRI, IL-6Rα) at the SN and caudate-putamen (CP) levels. In MPTP-treated animals we observed a significant increase in IL-1β, TNF-α and IL-6 mRNA expression levels both in the SN and CP in comparison with untreated mice. In addition, both mRNA and protein levels of IL-1RI, TNF-αRI and IL-6Rα were significantly enhanced in the SN of MPTP-treated mice in comparison to controls, whereas no significant differences were observed in the CP between treated and untreated mice. Overall, these results indicate a role of both pro-inflammatory cytokines and their receptors in the pathogenesis of PD.
