Analyzing the Spatiotemporal Interaction and Propagation of ATN Biomarkers in Alzheimer's Disease using Longitudinal Neuroimaging Data [PDF]
arXiv, 2021 Three major biomarkers: beta-amyloid (A), pathologic tau (T), and neurodegeneration (N), are recognized as valid proxies for neuropathologic changes of Alzheimer's disease. While there are extensive studies on cerebrospinal fluids biomarkers (amyloid, tau), the spatial propagation pattern across brain is missing and their interactive mechanisms with ...

Generation of amyloid β protein from its precursor is sequence specific
Neuron, 1995 Cerebral deposition of amyloid beta protein (A beta) is an early and critical feature of Alzheimer's disease. Here we analyze the substrate requirements of proteases ("beta-secretases") that cleave the beta-amyloid precursor protein (beta APP) at the N-terminus of A beta (Asp-597 of beta APP695) in intact human cells.

Advanced Science, EarlyView.Polyglutamine (polyQ) tract expansion (≥ 36 amino acids) within the N‐terminal region of the Huntingtin protein (Httex1) causes Huntington's disease (HD), for which the underlying causes are not well‐understood. The authors performed computer simulations to understand the cause of HD at the molecular level.

Supramolecular Gels as Active Tools for Reaction Engineering
Angewandte Chemie, EarlyView.The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Fractal Scaling of Cortical Matter, Amyloid Fragmentation and Plaque Formation across Rodents and Primates [PDF]
arXiv, 2014 Thermodynamic tools are well suited to connecting evolution of protein functionalities to mutations of amino acid sequences, especially for neuronal network structures. These tools enable one to quantify changes in modular structure and correlate them with corresponding changes in observable properties.

Insights into the variability of nucleated amyloid polymerization by a minimalistic model of stochastic protein assembly [PDF]
, 2015 Self-assembly of proteins into amyloid aggregates is an important biological phenomenon associated with human diseases such as Alzheimer's disease. Amyloid fibrils also have potential applications in nano-engineering of biomaterials. The kinetics of amyloid assembly show an exponential growth phase preceded by a lag phase, variable in duration as seen ...

Phototherapy via Modulation of β‐Amyloid in Combating Alzheimer's Disease
Aggregate, EarlyView.This review introduces the light‐regulated Aβ aggregation, highlighting four applications: photodynamic therapy (PDT), photothermal therapy (PTT), photopharmacology, and photobiomodulation (PBM) systems. It also summarizes the current issues and proposes the prospects of photo‐induced modulation of Aβ aggregation and clearance as a therapeutic strategy
