Role Of Gut Bacteria Linked To Neurodegenerative Diseases

Gut Bacteria and Neurodegenerative Diseases

As the toxic aggregates are capable of glowing under the microscope, colonization of certain bacteria species but not control bacteria, lit up not only the intestinal tissues, where the bacteria are but all over the worms’ bodies – in their muscles, nerves and even reproductive organs.

It was also noted that the offspring of affected worms also showed increased protein aggregation, despite the fact that these offspring never encountered the bacteria originally associated with the condition. This suggests that bacteria are capable of generating hereditary signals to offsprings.

The worms colonized by the “bad” bacteria also lost mobility, a common symptom of neurodegenerative diseases. The study findings thereby open possible connections between gut bacteria and protein misfolding.

“The worms are only one millimeter long, and they each have exactly 959 cells. But in many ways, they are a lot like us humans — they have intestines and muscles and nerves, but instead of being composed of billions of cells, each organ is just a handful of cells. They are like living test tubes. Their small size allows us to do experiments in a much more controlled way and answer important questions we can apply in future experiments with higher organisms and, eventually, people,” says, Czyz.

The team is also exploring the possible connections between antibiotic-resistant bacteria and protein misfolding.
