Targeting Bacterial Curli Fibrils to Prevent α-Synuclein Cross-Seeding

**Background and Rationale** Parkinson's disease (PD) is characterized by the accumulation of misfolded α-synuclein aggregates, primarily in the form of Lewy bodies and Lewy neurites. While the precise mechanisms underlying α-synuclein aggregation remain incompletely understood, emerging evidence suggests that the gut-brain axis plays a crucial role in PD pathogenesis. The "Braak hypothesis" proposes that α-synuclein pathology originates in the enteric nervous system and spreads to the central ...
