The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

open access: yesBrain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

open access: yesThe FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Targeting of the prion protein to the cytosol: mechanisms and consequences

open access: yes, 2010
Prion diseases are characterized by the conformational transition of the cellular prion protein (PrPC) into an aberrant protein conformer, designated scrapie-prion protein (PrPSc).

Proteostasis of organelles in aging and disease

open access: yesThe FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

The Role of the Simulation in Supporting Newly Graduated Nurses in Their First 5 Months of Working Transition: Findings From a Mixed‐Method Study

open access: yesJournal of Clinical Nursing, EarlyView.
ABSTRACT Aims To understand the role of simulation in ensuring the development of the competencies expected by newly graduated register nurses (NGRNs) from the work initiation up to 5 months of transition. Methods Mixed‐method study design. A longitudinal phase employing the Nurse Competence Scale (NCS, from 0 to 100, excellent) to assess the perceived

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,

Long‐term stability of horizontal bone augmentation at implant sites

open access: yesPeriodontology 2000, EarlyView.
Abstract Horizontal bone augmentation is a fundamental surgical procedure in regenerative implant dentistry. In recent decades, this procedure has evolved, enabling clinicians to achieve predictable and stable horizontal bone augmentation that supports dental implant restorations.

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Abnormal Expression of Proteolytic Stress‐Related Proteins and Protective Effect of Fibrinolytic Enzymes in Prion Diseases

open access: yesTransboundary and Emerging Diseases
Prion diseases are fatal, irreversible, and infectious neurodegenerative diseases caused by proteinase K‐resistant prion protein (PrPSc). Against PrPSc, several endogenous proteases involved in cellular degradation mechanisms can be activated to remove PrPSc.
