Researchers propose that Parkinson’s disease may start in the gut, not the brain

A perspective in The Journal of Clinical Investigation argues that environmental exposures may interact with the gut microbiome and intestinal barrier to trigger biological processes linked to Parkinson’s disease. The authors propose that cumulative environmental stressors can erode host resilience, promoting α-synuclein pathology, immune activation, and neurodegeneration.
