Apomorphine Targets the Pleiotropic Bacterial Regulator Hfq
Hfq is a bacterial regulator with key roles in gene expression. The protein notably regulates translation efficiency and RNA decay in Gram-negative bacteria, thanks to its binding to small regulatory noncoding RNAs. This property is of primary importance

Surface Properties of Aqueous Dispersions of Bovine Serum Albumin Fibrils
The surface properties of aqueous dispersions of worm-like fibril aggregates of bovine serum albumin (BSA) differ from those of the adsorption layers of the native protein. The dispersions of BSA fibrils are characterized by slower changes of the surface

Cryo-EM demonstrates the in vitro proliferation of an ex vivo amyloid fibril morphology by seeding
Here, the authors present the cryo-EM structure of in vitro amyloid fibrils from recombinant SAA1.1 protein that were formed by seeding with fibrils purified from systemic AA amyloidosis tissue.

Antisera to scrapie-associated fibril protein and prion protein decorate scrapie-associated fibrils [PDF]
Scrapie-associated fibrils (SAF) are an infection-specific structure observed in the unconventional-agent diseases. Polyclonal antisera raised to scrapie proteins were used to test the antigenic relationship between purified fibrils and SAF isolated from non-protease-treated synaptosomal-mitochondrial preparations.

Antiserum to scrapie-associated fibril protein cross-reacts with Spiroplasma mirum fibril proteins [PDF]
Protease-resistant fibril proteins purified from Spiroplasma mirum and from Creutzfeldt-Jakob disease-infected brain tissues reacted with antisera to scrapie-associated fibrils on Western immunoblot analysis. These data suggest that there are conformational similarities among spiroplasma proteins and infection-specific proteins of the transmissible ...

Quercetin Disaggregates Prion Fibrils and Decreases Fibril-Induced Cytotoxicity and Oxidative Stress
Transmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative diseases caused by misfolding and aggregation of prion protein (PrP). Previous studies have demonstrated that quercetin can disaggregate some amyloid fibrils, such as amyloid β ...

Instantaneous fibrillation of egg white proteome with ionic liquid and macromolecular crowding
The applicability of protein fibrils as functional biomaterials is limited due to low scalability of production process, slow kinetics, and requirement of expensive purified proteins.

Elevated temperatures accelerate the formation of toxic amyloid fibrils of hen egg‐white lysozyme
The formation of amyloid fibrils is critical for neurodegenerative diseases. Some physiochemical conditions can promote the conversion of proteins from soluble globular shapes into insoluble well‐organized amyloid fibrils.

Nanoparticles as catalysts for protein fibrillation [PDF]
The study by Linse et al. (1) published in this issue of PNAS observes that nanoparticles (NPs) can significantly enhance the rate of protein fibrillation, or the formation of fibrils, potentially leading to novel mechanisms for amyloid diseases as well as therapeutic opportunities for their treatment.
