Seeded aggregation
Web1 Mar 2024 · Seeded aggregation can also contribute to the cell-to-cell transmission of aggregates of Aβ [ 100 ], tau [ 101] (both associated with Alzheimer’s disease), and α-synuclein [ [102], [103], [104] ]. Such a cell-to-cell mechanism of transmission has been suggested to be akin to a prion infection. Web10 Aug 2024 · The current study demonstrates that aggregated α-synuclein is potent in cross-seeding of prion protein misfolding and aggregation in vitro, producing self-replicating states that can lead to transmissible prion …

Web28 Mar 2024 · Templated seeding is considered the underlying principle for cell-to-cell aggregate propagation. Agents that inhibit both de novo and seeded aggregation would thus be considered candidate disease-modifying drugs. In a separate study, we screened a small-molecule library for compounds that inhibit cell-to-cell propagation of α-synuclein.
