VOLUME | APR 2022 Exploring the Gut-Brain Connection in Parkinson’s Disease Using Mice and Cyanidin-3-O-Glucoside

Imagine a park that’s filled with playful animals and vibrant plants. Everything is perfectly balanced, from the number of squirrels to the variety of flowers. But one day, chaos ensues as the animals start misbehaving and the flowers wither away. This, my friends, is what happens in the gut microbiota of mice with Parkinson’s disease (PD). The delicate balance of gut bacteria is disrupted, leading to a cascade of metabolic changes that contribute to PD progression. However, hope comes in the form of cyanidin-3-O-glucoside, a natural compound found in certain fruits. In this study, researchers used a multi-omics approach to investigate how cyanidin-3-O-glucoside restores balance to the gut microbiota and protects against PD development. They analyzed metabolites and gut bacteria in PD mice treated with cyanidin-3-O-glucoside, uncovering key biomarkers and pathways involved in PD pathology. By understanding the complex interplay between host metabolism and gut microbiota, we can pave the way for more accurate diagnosis and targeted interventions for PD patients. So go ahead, dive into this fascinating research and unlock the secrets of the gut-brain connection in Parkinson’s disease!

BackgroundParkinson’s disease (PD) is a multifactorial degenerative disease of the central nervous system, which affects mostly older adults. To date, research has focused on the progression of PD. Simultaneously, it was confirmed that the imbalances in gut microbiota are associated with the onset and progression of PD. Accurate diagnosis and precise treatment of PD are currently deficient due to the absence of effective biomarkers.MethodsIn this study, the pharmacodynamic study of cyanidin-3-O-glucoside in PD mice was used. It intends to use the “imbalance” and “balance” of intestinal microecology as the starting point to investigate the “gut-to-brain” hypothesis using metabolomic-combined 16S rRNA gene sequencing methods. Simultaneously, metabolomic analysis was implemented to acquire differential metabolites, and microbiome analysis was performed to analyze the composition and filter the remarkably altered gut microbiota at the phylum/genera level. Afterward, metabolic pathway and functional prediction analysis of the screened differential metabolites and gut microbiota were applied using the MetaboAnalyst database. In addition, Pearson’s correlation analysis was used for the differential metabolites and gut microbiota. We found that cyanidin-3-O-glucoside could protect 1-methyl-4-phenyl-1,2,3,6− tetrahydropy ridine (MPTP)-induced PD mice.ResultsMetabolomic analysis showed that MPTP-induced dysbiosis of the gut microbiota significantly altered sixty-seven metabolites. The present studies have also shown that MPTP-induced PD is related to lipid metabolism, amino acid metabolism, and so on. The 16S rRNA sequencing analysis indicated that 5 phyla and 22 genera were significantly altered. Furthermore, the differential gut microbiota was interrelated with amino acid metabolism, and so on. The metabolites and gut microbiota network diagram revealed significant correlations between 11 genera and 8 differential metabolites.ConclusionIn combination, this study offers potential molecular biomarkers that should be validated for future translation into clinical applications for more accurately diagnosing PD. Simultaneously, the results of this study lay a basis for further study of the association between host metabolisms, gut microbiota, and PD.
