Researchers from the University of Vienna, University of Konstanz, and Albert Einstein College of Medicine have found that a microbial metabolite may be responsible for inducing Parkinson's-like symptoms. This discovery has the potential to change our understanding of the environmental triggers for Parkinson's disease.
Researchers from the University of Vienna, University of Konstanz, and Albert Einstein College of Medicine uncover a potential environmental trigger for Parkinson’s disease.
Published in Environment International, a groundbreaking study from the Institute of Biological Chemistry and Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna, in collaboration with the University of Konstanz and the Albert Einstein College of Medicine, reveals a microbial metabolite’s role in inducing Parkinson’s-like symptoms. This discovery could reshape our understanding of the environmental triggers of Parkinson’s disease.
The underlying causes of Parkinson’s disease, a debilitating neurodegenerative condition, are not well understood. While genetic mutations are known to cause Parkinson’s, a staggering 90% of cases are sporadic, with no clear genetic origin. Scientists suspect environmental factors could play a role – and substances like pesticides and industrial chemicals have been investigated for potential links to neurodegeneration. Among the possible culprits also are microbial metabolites.
Recent studies highlight the gut-brain axis’s importance, suggesting that our microbiome might influence neurodegenerative diseases. Notably, the gut microbiome of Parkinson’s patients differs from that of healthy individuals. Some microbial metabolites have even been shown to specifically target dopamine-producing neurons, which are crucially affected in Parkinson’s disease.
Motivated by these findings and the potential role of a specific bacterial metabolite in inducing Parkinson’s-like symptoms, researchers from the University of Vienna, the University of Konstanz, and the Albert Einstein College of Medicine embarked on a comprehensive study. They focused on a metabolite produced by the bacterium Streptomyces venezuelae,
