Open AccessMaturation-dependent changes in the size, structure and seeding capacity of Aβ42 amyloid fibrils
Many proteins self-assemble to form amyloid fibrils, which are highly organized structures stabilized by a characteristic cross-β network of hydrogen bonds. This process underlies a variety of human diseases a...

Open AccessThe Hsc70 disaggregation machinery removes monomer units directly from α-synuclein fibril ends
Molecular chaperones contribute to the maintenance of cellular protein homoeostasis through assisting de novo protein folding and preventing amyloid formation. Chaperones of the Hsp70 family can further disagg...

Open AccessControlled self-assembly of plant proteins into high-performance multifunctional nanostructured films
The abundance of plant-derived proteins, as well as their biodegradability and low environmental impact make them attractive polymeric feedstocks for next-generation functional materials to replace current pet...

Open AccessInfrared nanospectroscopy reveals the molecular interaction fingerprint of an aggregation inhibitor with single Aβ42 oligomers
Significant efforts have been devoted in the last twenty years to develo** compounds that can interfere with the aggregation pathways of proteins related to misfolding disorders, including Alzheimer’s and Pa...

Biomolecular condensates undergo a generic shear-mediated liquid-to-solid transition
Membrane-less organelles resulting from liquid–liquid phase separation of biopolymers into intracellular condensates control essential biological functions, including messenger RNA processing, cell signalling ...

Open AccessSingle molecule secondary structure determination of proteins through infrared absorption nanospectroscopy
The chemical and structural properties of biomolecules determine their interactions, and thus their functions, in a wide variety of biochemical processes. Innovative imaging methods have been developed to char...

Open AccessMicrofluidic deposition for resolving single-molecule protein architecture and heterogeneity
Scanning probe microscopy provides a unique window into the morphology, mechanics, and structure of proteins and their complexes on the nanoscale. Such measurements require, however, deposition of samples onto...

Cholesterol catalyses Aβ42 aggregation through a heterogeneous nucleation pathway in the presence of lipid membranes
Alzheimer’s disease is a neurodegenerative disorder associated with the aberrant aggregation of the amyloid-β peptide. Although increasing evidence implicates cholesterol in the pathogenesis of Alzheimer’s diseas...
