Sinus infection of Saccharomyces cerevisiae accelerates the aggregation of α-synuclein (α-syn) in A53T mice, which was caused by prion protein Sup35. Sup35 promotes α-syn aggregation in vitro and in vivo and leads to Parkinson's disease (PD)-like motor impairment in wildtype mice, suggesting that the yeast Sup35 triggers α-syn pathology in PD.
