Mechanistic insights into accelerated α-synuclein aggregation mediated by human microbiome-associated functional amyloids

Abstract excerpt

The gut microbiome has been shown to have key implications in the pathogenesis of Parkinson's disease (PD). The Escherichia coli functional amyloid CsgA is known to accelerate α-synuclein aggregation in vitro and induce PD symptoms in mice. However, the mechanism governing CsgA-mediated acceleration of α-synuclein aggregation is unclear. Here, we show that CsgA can form stable homodimeric species that correlate...
