5 days ago · Many tropocollagens then bind together to form a fibril, and many of these then form a fibre. A distinctive feature of collagen is the regular arrangement of amino acids in each of the three chains of these collagen subunits.
4 days ago · Preformed fibril models. A model that has been gaining popularity in recent years is the preformed fibril (PFF) model, in which preformed fibrils of human or mouse α-syn are injected into mice (Chung et al., 2019). Alpha-synuclein can be recombinantly expressed and fibrillization induced, commonly by shaking at 37°C.
2 days ago · The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
6 days ago · Thioflavin T (ThT) is a typical dye used to visualize the aggregation and formation of fibrillar structures, e.g., amyloid fibrils and peptide nanofibrils. ThT has been considered to produce stable fluorescence when interacting with aggregated proteins. For single-molecule localization microscopy (SMLM)-based optical super-resolution imaging, a photoswitching/blinking fluorescence property is ...
3 days ago · These characteristics contribute to the robust propagation of this fibril form, as supported by the structural similarity of early-onset-PD mutants. The group experimentally verified the structure with collaborators by producing the protein in the lab and checking it with various imaging methods to see if it matched the fibrils found in Parkinson's patients.
3 days ago · Researchers Capture Protein Tangle Formation in Real-Time. Protein tangles, known as amyloid-beta (A-beta) aggregates, are most famously linked to neurodegenerative illnesses like Alzheimer's. Nevertheless, despite its frequent attention, scientists have not been able to comprehend how A-beta assembles and disassembles fully. The way A-beta ...
4 days ago · Inspired by the prevalence of key peptide segments driving the fibril-like aggregation of amyloid proteins, the spontaneous association of oligopeptides which feature a diversity of nanosized, supramolecular architectures has been extensively investigated to construct functionalized supramolecular materials via a bottom-up approach using synthetic oligopeptides as building blocks [1,2,3,4 ...
3 days ago · Future studies should define whether cell-, region- and age-specific differences in metabolism of posttranslational modifications play a causative role in dictating strain identity and structural ...
2 days ago · Countless factors can impact the phenotypic variability observed among individuals with transthyretin amyloid polyneuropathy (ATTR-PN) and ATTR cardiomyopathy (ATTR-CM), according to findings from a review published recently in the Journal of Neurology.. A myriad of genetic, epigenetic, and environmental components can contribute to this variability in phenotype.
6 days ago · The authors' insilico analysis predict the ability of HRDC domain of BLM in parallel aggregation and fibril formation and proposes a potential role for BLM in neurodegenerative diseases. Bloom’s syndrome (BS) is a rare autosomal recessive human genetic disorder characterized by several abnormalities like short stature, immunodeficiency, sun sensitivity, male sterility, and cancer predisposition.
