Abstract:
The aim of this study is to investigate the effect of ginseng protein (GP) on MPTP induced Parkinson's disease (PD) in mice. Constructing a chronic PD model by intraperitoneal injection of MPTP in C57BL/6 mice. Behavioural experiments have shown that GP can significantly improve behavioural disorders in chronic PD model mice. GP treatment also restored the MPTP induced decrease in dopamine levels, thereby alleviating PD related pathology. Pathology of brain and intestinal tissues showed that GP significantly improved the distribution of hippocampal cells and striatal structure in mice, reduced the aggregation of alpha synuclein (α - Syn), and increased the expression of tyrosine hydroxylase (TH) in the brain. The analysis of gut microbiota showed that GP partially restored the disruption of gut microbiota in chronic PD mice. Ginseng total protein can improve behavioural disorders, brain and intestinal pathological damage, and gut microbiota disorders in C57BL/6 mice with chronic Parkinson's disease.
Insights
Ginseng protein (GP) significantly improved Parkinson's disease symptoms in mice by restoring dopamine levels and reducing brain and gut pathology. This study highlights GP's therapeutic potential for Parkinson's disease.
Area of Science:
- Neuroscience
- Pharmacology
- Microbiology
Background:
- Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor deficits and dopaminergic neuron loss.
- MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is commonly used to induce PD models in rodents.
- Gut microbiota dysbiosis is increasingly recognized as a contributing factor in PD pathogenesis.
Purpose of the Study:
- To investigate the therapeutic effects of ginseng protein (GP) on MPTP-induced Parkinson's disease in a mouse model.
- To evaluate GP's impact on behavioral deficits, neurotransmitter levels, neuropathology, and gut microbiota.
Main Methods:
- A chronic Parkinson's disease model was established in C57BL/6 mice using MPTP injections.
- Behavioral tests were conducted to assess motor function.
- Dopamine levels, alpha-synuclein aggregation, and tyrosine hydroxylase expression were analyzed in brain tissues.
- Histopathological examination of brain and intestinal tissues was performed.
- Gut microbiota composition was analyzed.
Main Results:
- Ginseng protein (GP) treatment significantly improved behavioral impairments in MPTP-induced PD mice.
- GP administration restored dopamine levels and increased tyrosine hydroxylase expression in the brain.
- GP treatment reduced alpha-synuclein aggregation and improved hippocampal and striatal structure.
- GP partially ameliorated gut microbiota dysbiosis observed in PD mice.
- GP alleviated both brain and intestinal pathological damage.
Conclusions:
- Ginseng protein demonstrates significant neuroprotective and therapeutic effects in a mouse model of Parkinson's disease.
- GP can improve behavioral outcomes, restore dopaminergic function, and mitigate neuropathological hallmarks of PD.
- GP's positive impact on gut microbiota suggests a potential role in addressing the gut-brain axis in Parkinson's disease.
