WebMay 30, 2024 · EGCG, the most abundant favanol in green tea, is one of the few natural compounds known to inhibit amyloid fibril formation of proteins associated with neurodegeneration, and to disaggregate amyloid fibrils. Little is known of the mechanism of molecular action of EGCG, or how it or other small molecules interact with amyloid fibrils. … WebAug 16, 2024 · Cooperative amyloid fibre binding and disassembly by the Hsp70 disaggregase Although amyloid fibres are highly stable protein aggregates, a specific combination of human Hsp70 system chaperones can disassemble them, including fibres formed of α-synuclein, huntingtin, or Tau.

WebThus disaggregation of tau fibrils could be a therapeutic approach to AD. The small molecule EGCG, abundant in green tea, has long been known to disaggregate tau and other amyloid fibrils, but EGCG has poor drug-like properties, failing to fully penetrate the brain. Here we have cryogenically trapped an intermediate of brain-extracted tau ...
