We investigated the effect of submicellar lipids on amyloid fibril formation. Thioflavin T fluorescence studies showed that submicellar levels of the short-chain phospholipids, dipentanoylphosphatidylcholine and dihexanoylphosphatidylcholine, strongly inhibited amyloid fibril formation by an 11-residue peptide derived from human apolipoprotein C-II (apoC-II(60-70)). In contrast, sedimentation equilibrium analysis of these peptide-lipid mixtures indicated the presence of soluble oligomeric… Expand
High-affinity amphipathic modulators of amyloid fibril nucleation and elongation.
Low-molecular-weight amphipathic lipids and detergents may serve as useful, stage-specific modulators of protein self-assembly and fibril formation in disease-prevention strategies. Expand
Inhibition of peptide aggregation by lipids: insights from coarse-grained molecular simulations.
Simulation of the aggregation of an amyloidogenic peptide in the absence and presence of a short-chained lipid suggests that the morphology of peptide aggregates is strongly dependent on their local lipid environment, with greater contacts with lipids resulting in the formation of more elongated aggregates.

The Role of Lipid in Misfolding and Amyloid Fibril Formation by Apolipoprotein C-II.
The studies of the effects of lipid at each stage of amyloid formation have revealed complex behaviour dependent on the chemical nature of the lipid molecule, its association state, and the protein:lipid ratio. Expand
A cyclic peptide inhibitor of apoC-II peptide fibril formation: mechanistic insight from NMR and molecular dynamics analysis.
The structural studies suggest that the inhibitory activity of cyc[60-70] is mediated by an elongated structure with inherent flexibility and distinct hydrophobic and hydrophilic faces, enabling cyc to interact transiently with fibrillogenic peptides and inhibit fibril assembly. Expand
Effects of mutation on the amyloidogenic propensity of apolipoprotein C-II(60-70) peptide.
The results showed that the critical nucleus size for fibril formation by apoC-II(60-70) may not be very large, since tetrameric oligomers in anti-parallel configuration were very stable within the 100 ns of simulations. Expand
Exploring the inhibitory activity of short-chain phospholipids against amyloid fibrillogenesis of hen egg-white lysozyme.
The molecular dynamics simulations results demonstrated that the observed inhibitory action of short-chain phosoholipids against hen lysozyme fibrillogenesis might be attributable to the interference of β-strand extension by the binding of phospholipid to lyso enzyme's β-sheet-rich region. Expand
Apolipoprotein C-II Adopts Distinct Structures in Complex with Micellar and Submicellar Forms of the Amyloid-Inhibiting Lipid-Mimetic Dodecylphosphocholine.
It is shown that the micellar state of an inhibitory lipid can have a very significant effect on protein conformation, with micelles stabilizing a particular α-helical structure, whereas submicellar lipids stabilize a very different dimeric, α- HELICAL structure, indicating that lipids may have an important role in the development and progression of amyloid-related diseases.

Effects of graphitic nanomaterials on the dissociation pathway of amyloidogenic peptide dimer
The potential for nanomaterials to interact with biological molecules has been under significant scrutiny, specifically, in their possible role as scaffolds for protein aggregation that can result inExpand
Amyloid fibrillation and cytotoxicity of insulin are inhibited by the amphiphilic surfactants.
Insulin fibrillation may be inhibited by both surfactants in a dose-dependent fashion and the addition of either surfactant at the concentrations studied attenuated insulin fibril-induced cytotoxicity in both PC12 and SH-SY5Y cell lines. Expand
"Janus" Cyclic Peptides: A New Approach to Amyloid Fibril Inhibition?
Using classical molecular dynamics and electronic structure calculations, insight is provided into the interaction between the amyloidogenic peptide apoC-II(60–70) and its cyclic derivative, cyc, suggesting that cyc can be an effective fibril inhibitor due to its amphipathic character, like that of the "Janus"-type particles.
