Fibril Breaking Accelerates α-Synuclein Fibrillization [PDF]
The Journal of Physical Chemistry B, 2015 The formation of amyloid fibrils of α-synuclein (αSyn), the key protein in Parkinson's disease, is an autocatalytic process that is seeded by mature αSyn fibrils. Based on systematic measurements of the dependence of the fibril growth rate on the concentrations of monomers and preformed fibrillar seeds, we propose a mechanism of αSyn aggregation that ...

Conformational Variability of Amyloid-β and the Morphological Diversity of Its Aggregates
Molecules, 2022 Protein folding is the most fundamental and universal example of biomolecular self-organization and is characterized as an intramolecular process. In contrast, amyloidogenic proteins can interact with one another, leading to protein aggregation.

Nature Reviews Disease Primers, 2016 Atrial fibrillation (AF) is the most common sustained cardiac rhythm disorder, and increases in prevalence with increasing age and the number of cardiovascular comorbidities. AF is characterized by a rapid and irregular heartbeat that can be asymptomatic or lead to symptoms such as palpitations, dyspnoea and dizziness.

Exploring Spiroplasma Biology: Opportunities and Challenges
Frontiers in Microbiology, 2020 Spiroplasmas are cell-wall-deficient helical bacteria belonging to the class Mollicutes. Their ability to maintain a helical shape in the absence of cell wall and their motility in the absence of external appendages have attracted attention from the ...

Pharmaceutics, 2022 Senile plaques composed of amyloid β (Aβ) fibrils are considered the leading cause of Alzheimer’s disease (AD). Molecules with the ability to inhibit Aβ aggregation and/or promote Aβ clearance are thus a promising approach for AD therapy.

Australian Journal of General Practice, 2019 Atrial fibrillation (AF) is increasingly common among Australia's ageing population and carries significant morbidity and mortality. Its detection through screening, cardiac device interrogation and/or symptoms of AF brings with it a number of significant clinical issues.The aim of this article is to outline a systematic approach to the management of ...

α-Synuclein Fibrils as Penrose Machines: A Chameleon in the Gear
Biomolecules, 2022 In 1957, Lionel Penrose built the first man-made self-replicating mechanical device and illustrated its function in a series of machine prototypes, prefiguring our current view of the genesis and the proliferation of amyloid fibrils.
