The substantia nigra in Parkinson's disease (PD) is depleted of dopaminergic neurons and contains fibrillar Lewy bodies comprising primarily alpha-synuclein. We screened a library to identify drug-like molecules to probe the relation between neurodegeneration and alpha-synuclein fibrilization. All but one of 15 fibril inhibitors were catecholamines related(More)
Fibrillar alpha-synuclein is a component of the Lewy body, the characteristic neuronal inclusion of the Parkinson's disease (PD) brain. Both alpha-synuclein mutations linked to autosomal dominant early-onset forms of PD promote the in vitro conversion of the natively unfolded protein into ordered prefibrillar oligomers, suggesting that these protofibrils,(More)
Parkinson's disease (PD) is a neurodegenerative disorder attributed to the loss of dopaminergic neurons from the substantia nigra. Some surviving neurons are characterized by cytoplasmic Lewy bodies, which contain fibrillar alpha-synuclein. Two mutants of human alpha-synuclein (A53T and A30P) have been linked to early-onset, familial PD. Oligomeric forms of(More)
Environmental factors, such as acidic pH, facilitate the assembly of α-synuclein (α-Syn) in aggregates, but the impact of pH on the very first step of α-Syn aggregation remains elusive. Recently, we developed a single-molecule approach that enabled us to measure directly the stability of α-Syn dimers. Unlabeled α-Syn monomers were immobilized on a(More)

BIS Working Papers are written by members of the Monetary and Economic Department of the Bank for International Settlements, and from time to time by other economists, and are published by the Bank. The papers are on subjects of topical interest and are technical in character. The views expressed in them are those of their authors and not necessarily the(More)
