Background:
Feruloylated oligosaccharides (FOs) are natural esterification products of ferulic acid and oligosaccharides.
Study Design:
In this study, we examined whether FOs contribute to the ensured survival of nigrostriatal dopamine neurons and inhibition of neuroinflammation in Parkinson's disease (PD).
Methods:
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30 mg/kg) was injected intraperitoneally into mice to establish a Parkinson's disease (PD) mouse model. FOs (15 and 30 mg/kg) were orally administered daily to the MPTP-treated mice. The rotarod test, balance beam test, immunofluorescence, enzyme-linked immunosorbent assay (ELISA), quantitative PCR (qPCR), and western blot analyses were performed to examine the neuroprotective effects of FOs on MPTP-treated mice.
Results:
Our study indicated that FOs increased the survival of dopamine neurons in the substantia nigra pars compacta (SNc) of the MPTP-treated mice. The neuroprotective effects of FOs were accompanied by inhibited glial activation and reduced inflammatory cytokine production. The mechanistic experiments revealed that the neuroprotective effects of FOs might be mediated through the activation of the ERK/CREB/BDNF/TrkB signalling pathway.
Conclusion:
This study provides new insights into the mechanism underlying the anti-neuroinflammatory effect of phytochemicals and may facilitate the development of dietary supplements for PD patients. Our results indicate that FOs can be used as potential modulators for the prevention and treatment of PD.
Insights
Feruloylated oligosaccharides (FOs) protect dopamine neurons and reduce inflammation in a Parkinson's disease mouse model. These findings suggest FOs may be beneficial for Parkinson's disease prevention and treatment.
Area of Science:
- Neuroscience
- Pharmacology
- Biochemistry
Background:
- Feruloylated oligosaccharides (FOs) are naturally occurring compounds derived from ferulic acid and oligosaccharides.
- Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons and neuroinflammation.
Purpose of the Study:
- To investigate the neuroprotective potential of FOs in a mouse model of Parkinson's disease.
- To determine if FOs can inhibit neuroinflammation and promote the survival of nigrostriatal dopamine neurons.
Main Methods:
- A Parkinson's disease mouse model was established using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).
- Mice were treated with FOs (15 and 30 mg/kg) orally.
- Neuroprotection was assessed using behavioral tests, immunofluorescence, ELISA, qPCR, and Western blot analysis.
Main Results:
- FOs significantly increased the survival of dopamine neurons in the substantia nigra pars compacta (SNc).
- FO treatment inhibited glial activation and reduced the production of inflammatory cytokines.
- Mechanistic studies indicated that FOs activate the ERK/CREB/BDNF/TrkB signaling pathway.
Conclusions:
- FOs exhibit neuroprotective effects against MPTP-induced neurodegeneration in mice.
- The anti-neuroinflammatory effects of FOs may be mediated by the ERK/CREB/BDNF/TrkB pathway.
- FOs show potential as dietary supplements for the prevention and treatment of Parkinson's disease.
