The role of first-stage β-amyloid aggregation in the development of the Alzheimer disease, is widely accepted but still unclear. Intimate interaction with the cell membrane is invoked. We designed Neutron Reflectometry experiments to reveal the existence and extent of the interaction between β-amyloid (Aβ) peptides and a lone customized biomimetic membrane, and their dependence on the aggregati...
Protein magic angle spinning (MAS) NMR spectroscopy has generated structural models of several amyloid fibril systems, thus providing valuable information regarding the forces and interactions that confer the extraordinary stability of the amyloid architecture. Despite these advances, however, obtaining atomic resolution information describing the higher levels of structural organization within...
Summary Peptides display a range of important properties, controlled by the intrinsic nature organic side chains, regarding redox activity, charge density, and structure. Here, we demonstrate new synthetic approach to insert non-coded amino acids that contain metal oxide groups into desired peptide sequence with commercial synthesizer. This allowed us design isolate highly anionic pept...
The amyloid β (A β) peptide is important in the context of Alzheimer's disease, since it is one of the major components of the fibrils that constitute amyloid plaques. Agents that can influence fibril formation are important, and of those, membrane mimics are particularly relevant, because the hydrophobic part of A β suggests a possible membrane activity of the peptide. We employed spin-label E...
