Researchers found that transferrin can assemble into worm-like fibrils when dried, exposing iron and potentially causing cell damage. This process may be linked to the deposition of iron in the brain and contribute to neurodegenerative diseases such as Parkinson's, Alzheimer's, and Huntington's.
New research by University of Illinois at Chicago chemists identifies intermediate step in amyloid plaque formation as a toxic culprit. Tiny spheres averaging 20 nanometers assemble into sheet-like structures comparable to fibrils, making them more than 10 times poisonous.
New research from MIT reveals a unified explanation for bone's toughness, incorporating several previously proposed theories. The study finds that bone's atomistic structure plays a crucial role in a toughening mechanism that allows it to tolerate small cracks and maintain its strength.
Researchers found that an imbalance between two peptides, AB40 and AB42, can lead to the formation of senile plaques and dementia. Introducing more AB40 may stop or slow down Alzheimer's development by balancing with AB42.
Researchers have discovered that Alzheimer's, Parkinson's, and type 2 diabetes share a common molecular mechanism, involving amyloid fibrils with a universal 'molecular zipper' structure. This finding could lead to new diagnostic tools and treatment options through 'structure-based drug design'.
Scientists have uncovered the molecular structure of cartilage's collagen fibrils, a key factor in osteoarthritis. The discovery could lead to treatments that prevent fibril deterioration and ultimately alleviate joint pain.
Researchers found that mice born to mothers with senile amyloidosis exhibited elevated levels of amyloid fibrils, accelerating disease onset. The presence of fibrils in the milk of affected mothers was confirmed, demonstrating transmission via nursing.
Researchers have discovered a potential treatment for Alzheimer's disease by combining gold nanoparticles with microwave radiation. The approach breaks up beta amyloid fibrils and reduces protein re-aggregation, offering hope for other neurodegenerative diseases like Parkinson's and Huntington's.
Researchers have determined the structure of pre-fibril assemblies, smaller assemblies that may be toxic culprits in Alzheimer's disease. The findings provide a new clue to understanding how these molecules interact and may lead to designing molecules that prevent misfolding proteins.
Scientists at UC Santa Barbara have made a groundbreaking discovery about the molecular mechanisms that hold human bone together, revealing a 'glue' that absorbs shock and helps prevent fractures. The findings may lead to new therapies for bone fracture treatment and prevention.
Researchers at UCLA have discovered a 'molecular zipper' structure in proteins linked to Alzheimer's, Parkinson's and mad cow disease. The discovery provides a potential rational basis for developing drugs to fight these diseases.
Researchers have gained a detailed understanding of the interconnected protein segments that form amyloid fibrils, a key feature in various diseases. The structure reveals a 'spine' made up of short zippers that are tightly bonded together.
Researchers found that small soluble protein clusters called oligomers cause neurotoxicity by increasing membrane permeability. This challenges the long-held idea that insoluble fibrils are responsible for disease symptoms.
Researchers find specific shapes of amyloid fibrils, not amino acid sequences, determine prion infectivity across species. This breakthrough offers insights into the mechanisms behind prion diseases and potential transmission between previously separate animals.
Researchers found that rifampicin stabilizes alpha-synuclein in a soluble form, preventing fibril formation and disaggregating existing fibrils. This finding suggests potential therapeutic benefits for Parkinson's disease when administered early in the disease process.
Researchers used computer simulations to visualize the formation of amyloid fibrils, similar to those found in Alzheimer's and Parkinson's patients. The study suggests that understanding how these fibrils form could lead to discoveries of how to slow or halt their growth.
Researchers discovered that apolipoprotein E and clusterin proteins can delay amyloid plaque formation in mice with Alzheimer's-like brain damage. The findings imply that these proteins cooperate to suppress Abeta protein levels and deposition, paving the way for future drug or gene therapy treatments.
Researchers used AFM to study the effects of two monoclonal antibodies on beta amyloid peptide aggregation. The m266.2 antibody effectively inhibited protofibril formation, suggesting a promising approach for understanding conformational diseases like Alzheimer's.
Myxococcus xanthus bacteria evolved the ability to swarm socially on soft agar without filamentous appendages (pili), relying on an enhanced adhesive matrix composed of fibrils. This cooperative behavior depends on individual cells contributing to a public commons, enabling efficient swarming and cooperation.
USC researchers have successfully used gene therapy to prompt mouse cells to produce human collagen, a crucial step towards treating patients with dystrophic epidermolysis bullosa. This breakthrough could lead to the development of new treatments for this debilitating skin condition, which causes blisters and permanent scars.
Researchers at UNC-CH discovered a pentapeptide that breaks apart collagen fibrils, allowing for improved restricted movement due to joint injuries. The discovery has the potential to lead to new treatments, including injecting peptides into patients to loosen up stiff joints.
