摘要：

(Figure Presented) Out in the cold: Amyloid fibrils formed by the protein α-synuclein, one of the key players in Parkinson's disease, are rapidly dissociated in supercooled water at -15°C (see TEM images), conditions in which many globular proteins remain folded. NMR studies indicate that the weakening of hydrophobic and electrostatic interactions contribute to the cold-induced destabilization of the amyloid fibrils. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
