Parkinson's disease (PD) is characterized by the degeneration of dopaminergic neurons in the substantia nigra, and it has been reported that α-synuclein accumulates in the gut and then affects the brain along the gut-brain axis. In this study, we used Enterococcus faecium (EF), which was probiotics, that confer health benefits on the host when administered in adequate amounts. C57BL/6 mice, a model of PD induced by MPTP, were treated with EF (1ⅹ1012 CFU/mL). The study showed that motor dysfunction in MPTP-induced PD model mice improved. Additionally, EF was found to decrease the accumulation o
