The Thy1-αSyn (alpha-synuclein overexpressing) mouse  is predestined to develop a mousey equivalent of Parkinson’s disease. However, squeaky-clean ‘boy in the bubble’ mice did not develop the predicted motor deficits. Remarkably, antibiotic treatment ameliorates the phenotype while microbial recolonisation promotes it. This is a true example of gene versus environment demonstrating that gut microbiota are required for motor deficits, microglia activation and αSyn …
