Deposition of insoluble fibrillar aggregates of β-amyloid (Aβ) peptides in the brain is a hallmark of Alzheimer's disease. Apart from forming fibrils, these peptides also exist as soluble aggregates. Fibrillar and a variety of nonfibrillar aggregates of Aβ have also been obtained in vitro. Hexafluoroisopropanol (HFIP) has been widely used to dissolve Aβ and(More)
BACKGROUND Amyloid fibrils, which are implicated in several diseases, are highly ordered structures formed by aggregation of proteins. Intriguingly, several short peptides, some of which are unrelated to the disease-causing proteins, also aggregate to form amyloid fibrils in vitro. The aggregation behavior of these short peptides can be modulated so that(More)
Fluorinated alcohols such as hexafluoroisopropanol (HFIP) and trifluoroethanol (TFE) have the ability to promote α-helix and β-hairpin structure in proteins and peptides. HFIP has been used extensively to dissolve various amyloidogenic proteins and peptides including Aβ, in order to ensure their monomeric status. In this paper, we have investigated the(More)
