Rapid generation of prion disease models using AAV‐delivered PrP variants in knockout mice

Brain Pathology, EarlyView.
We developed a rapid AAV‐based system to generate prion disease models in weeks rather than months. Following systemic AAV9P31 delivery of modified PrP to knockout mice, we achieved brain‐wide expression and successful propagation of both classical (RML) and atypical (GSS‐A117V) prion strains.

Distinct regional patterns of synaptic vulnerability across hippocampal and parahippocampal subregions in Alzheimer's disease

Brain Pathology, EarlyView.
Synaptic loss in Alzheimer's disease predominantly affects the entorhinal cortex and parahippocampal gyrus. Amyloid‐β and p‐tau pathology show global associations with synaptic density but are limited in specific subregions. Instead, axonal damage associates with synaptic loss locally and in interconnected subregions.

Vesicular glutamate transporter VGLUT2 expression emerges in substantia nigra dopamine neurons in mouse models of parkinsonism in the absence of neurodegeneration

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Subsets of midbrain dopamine (DA) neurons express the vesicular glutamate transporter VGLUT2 and can release the excitatory neurotransmitter glutamate. VGLUT2+ DA neurons of the substantia nigra pars compacta (SNc) were shown to be more resistant to neurodegeneration in animal models of Parkinson's disease (PD ...

E3 ligase Praja1 mediates ubiquitination and degradation of microtubule‐associated protein tau

The FEBS Journal, EarlyView.
E3 ligase Praja1, but not its paralogue Praja2, recognizes and ubiquitinates tau protein for proteasomal degradation. This newly identified function of Praja1‐mediated tau degradation suggests its role in protein quality control, which may provide insights into the pathogenesis of tauopathies.

Proteostasis of organelles in aging and disease

The 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 ...

Uncovering a previously unknown function of polyphosphate in polyadenylated RNA‐induced amyloidogenesis of Hfq

The FEBS Journal, EarlyView.
Polyphosphate interaction with Hfq and RNA drives phase separation and amyloid self‐assembly, uncovering a previously unrecognized role for polyP in bacterial stress responses. Our findings reveal new insights into the molecular mechanisms of RNA‐mediated phase separation, highlighting the role of polyP as a key modulator of this process. Polyphosphate

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

Journal 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,
