Inhibition of Amyloid Peptide Fibrillation by Inorganic Nanoparticles: Functional Similarities with Proteins [PDF]

open access: yesAngewandte Chemie, 2011
Aggregation of amyloid-β peptides (Aβ) into fibrils is the key pathological feature of many neurodegenerative disorders. Typical drugs inhibit Aβ fibrillation by binding to monomers in 1:1 ratio and display low efficacy. Here, we report that model CdTe nanoparticles (NPs) can efficiently prevent fibrillation of Aβ associating with 100–330 monomers at ...

Inhibition of the NFATc4/ERK/AKT Pathway and Improvement of Thiol-Specific Oxidative Stress by Dronedarone Possibly Secondary to the Reduction of Blood Pressure in an Animal Model of Ventricular Hypertrophy

open access: yesFrontiers in Physiology, 2020
Untreated chronic hypertension causes left ventricular hypertrophy, which is related to the occurrence of atrial fibrillation. Dronedarone is an antiarrhythmic agent recently approved for atrial fibrillation.

Amyloid Fibrils of Pisum sativum L. Vicilin Inhibit Pathological Aggregation of Mammalian Proteins

open access: yesInternational Journal of Molecular Sciences, 2023
Although incurable pathologies associated with the formation of highly ordered fibrillar protein aggregates called amyloids have been known for about two centuries, functional roles of amyloids have been studied for only two decades. Recently, we identified functional amyloids in plants. These amyloids formed using garden pea Pisum sativum L.

Protein Disulfide Isomerase Interacts with Tau Protein and Inhibits Its Fibrillization

open access: yesPLoS ONE, 2013
Tau protein is implicated in the pathogenesis of neurodegenerative disorders such as tauopathies including Alzheimer disease, and Tau fibrillization is thought to be related to neuronal toxicity. Physiological inhibitors of Tau fibrillization hold promise for developing new strategies for treatment of Alzheimer disease.

Heterologous Stacking of Prion Protein Peptides Reveals Structural Details of Fibrils and Facilitates Complete Inhibition of Fibril Growth [PDF]

open access: yesJournal of Biological Chemistry, 2009
Fibrils play an important role in the pathogenesis of amyloidosis; however, the underlying mechanisms of the growth process and the structural details of fibrils are poorly understood. Crucial in the fibril formation of prion proteins is the stacking of PrP monomers.

Curcumin Reduces Amyloid Fibrillation of Prion Protein and Decreases Reactive Oxidative Stress

open access: yesPathogens, 2013
Misfolding and aggregation into amyloids of the prion protein (PrP) is responsible for the development of fatal transmissible neurodegenerative diseases.

Biomimetic Surface Engineering to Modulate the Coffee-Ring Effect for Amyloid-β Detection in Rat Brains

open access: yesBiomimetics, 2023
Surface engineering of nanoparticles has been widely used in biosensing and assays, where sensitivity was mainly limited by plasmonic colour change or electrochemical responses.

Understanding Inhibition of Protein Amyloid Fibril Formation

open access: yes, 2023
Dažniausiai pasitaikantys neurodegeneraciniai sutrikimai yra Alzheimerio ir Parkinsono ligos. Nepaisant skirtumų tarp kognityvinių simptomų, pasireiškimo vietos organizme, bei progresavimo greičio, šių ligų patologiniai požymiai yra panašūs ir siejami su baltymų agregacija į netirpius ir neuronams toksiškus darinius.

Factor Xa inhibitor, edoxaban ameliorates renal injury after subtotal nephrectomy by reducing epithelial‐mesenchymal transition and inflammatory response

open access: yesPhysiological Reports, 2022
Chronic kidney disease (CKD) is an increasing and life‐threatening disease worldwide. Recent evidence indicates that blood coagulation factors promote renal dysfunction in CKD patients.

Plant Polyphenols Inhibit Functional Amyloid and Biofilm Formation in Pseudomonas Strains by Directing Monomers to Off-Pathway Oligomers

open access: yesBiomolecules, 2019
Self-assembly of proteins to β-sheet rich amyloid fibrils is commonly observed in various neurodegenerative diseases. However, amyloid also occurs in the extracellular matrix of bacterial biofilm, which protects bacteria from environmental stress ...
