Factors influencing compact-extended structure equilibrium in oligomers of aβ1-40 peptide--an ion mobility mass spectrometry study.

Abstract excerpt

Oligomers formed by amyloid β (Aβ) peptide are widely believed to be the main neurotoxic agent in Alzheimer's disease. Studies discovered a broad variety of oligomeric forms, which display different levels of toxicity. Some of these forms may further assemble into mature fibrils, while other might be off-pathway from conversion to fibrils and assemble into alternative forms. To better understand a relationship...
