A novel, resistance-linked ovine PrP variant and its equivalent mouse variant modulate the in vitro cell-free conversion of rPrP to PrPres [PDF]

open access: yes, 2006
Prion diseases are associated with the conversion of the normal cellular prion protein, PrPC, to the abnormal, disease-associated form, PrPSc. This conversion can be mimicked in vitro by using a cell-free conversion assay. It has recently been shown that

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

open access: yesBrain 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

Small critical RNAs in the scrapie agent [PDF]

open access: yes, 2009
Unconventional infectious agents cause transmissible spongiform encephalopathy (TSE) diseases including scrapie and bovine spongiform encephalopathy (BSE) in animals and Creutzfeldt-Jakob disease in humans. The protein only hypothesis claims that the TSE

Inhibition of group-I metabotropic glutamate receptors protects against prion toxicity.

open access: yesPLoS Pathogens, 2017
Prion infections cause inexorable, progressive neurological dysfunction and neurodegeneration. Expression of the cellular prion protein PrPC is required for toxicity, suggesting the existence of deleterious PrPC-dependent signaling cascades.

α‐Synuclein strain homogeneity in multiple system atrophy subtypes

open access: yesBrain 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 ...

First Report of Single Nucleotide Polymorphisms (SNPs) of the Leporine Shadow of Prion Protein Gene (SPRN) and Absence of Nonsynonymous SNPs in the Open Reading Frame (ORF) in Rabbits

open access: yesAnimals
Prion disorders are fatal infectious diseases that are caused by a buildup of pathogenic prion protein (PrPSc) in susceptible mammals. According to new findings, the shadow of prion protein (Sho) encoded by the shadow of prion protein gene (SPRN) is ...

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

open access: yesThe 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.

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

open access: yesThe 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.

Bone Grafts: Everything You Need to Know

open access: yesJournal 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

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,
