Diverse Misfolded Conformational Strains and Cross-seeding of Misfolded Proteins Implicated in Neurodegenerative Diseases

Frontiers in Molecular Neuroscience, 2019
Numerous neurodegenerative diseases including prion, Alzheimer’s and Parkinson’s diseases are characterized by accumulation of protein aggregates in brain.

Interlaboratory performance testing on EPIC v2.0 CNS tumor profiling demonstrates high reproducibility of tumor classification but reveals the need for harmonized copy number variation reporting

Brain Pathology, EarlyView.
Using the Infinium MethylationEPIC v2.0 array and Heidelberg Brain Tumor Classifier v12.8, 24 international laboratories achieved highly reproducible CNS tumor classification (97.9% correct; median β‐correlation r = 0.99), while copy number variation interpretation showed substantial interlaboratory variability, highlighting the need for harmonized CNV

α‐Synuclein strain homogeneity in multiple system atrophy subtypes

Brain Pathology, EarlyView.
Two different subtypes of multiple system atrophy are recognized: MSA‐C and MSA‐P. In this manuscript, Lau et al. investigate whether MSA‐C and MSA‐P are caused by different strains of α‐synuclein aggregates. By performing conformational fingerprinting experiments as well as in vitro and in vivo seeding assays, their findings suggest that both MSA‐C ...

Molecular dynamics simulations elucidate the misfolding mechanisms of secretion‐defective pancreatic lipase variants

The FEBS Journal, EarlyView.
Misfolding mutations in pancreatic lipase have been identified as potential contributors of chronic pancreatitis, an inflammatory disease of the human pancreas. Here, we describe the effect of these misfolding mutations on pancreatic lipase structure using molecular dynamics simulations and structural modeling.

Novel anti-prion compounds screening in prion-infected cell culture model combined with surface plasmon resonance analysis

Scientific Reports
Prions are misfolded proteins (PrPSc) capable of inducing the same conformational change in normal prion proteins (PrPC). These aberrant proteins are responsible for neurodegenerative diseases in animals and humans, for which no effective treatments ...

Constrictions and shear stress are key determinants of amyloidogenic light chain (AL) amyloidosis

The FEBS Journal, EarlyView.
In this study, we investigate how flow constrictions and shear stress trigger cardiac antibody light chain (AL) fibril formation and deposition. We mimic the mechanical forces exerted by the heart and the microvasculature network using a mini‐peristaltic pump setup and a grid‐type microchannel network, respectively.

Change in tau phosphorylation associated with neurodegeneration in the ME7 model of prion disease

, 2010
Hyperphosphorylation of the microtubule-associated protein tau is a significant determinant in AD (Alzheimer's disease), where it is associated with disrupted axonal transport and probably causes synaptic dysfunction.

Bone Grafts: Everything You Need to Know

Journal of Periodontal Research, EarlyView.
This review classifies bone grafts (autograft, allograft, xenograft, synthetic) by source and osteogenic/inductive/conductive potential, linking material properties and mechanisms to clinical indications in periodontal and dental regeneration. Key challenges—limited osteoinduction, poor vascularisation, unbalanced resorption, handling difficulties, and
