Detection of TDP‐43 seeds in CSF of presymptomatic and symptomatic genetic FTD/ALS

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION Seed amplification assays (SAAs) have shown promising results in detecting misfolded transactive response (TAR) DNA‐binding protein 43 (TDP‐43) in cerebrospinal fluid (CSF) of genetic frontotemporal dementia (FTD). To date, the use of SAA has yet to be evaluated in presymptomatic individuals.

The Risk of Transmission of Genetic Prion Diseases is Greater Than 50%

European Journal of Neurology, Volume 32, Issue 12, December 2025.
This study investigated whether transmission ratio distortion (TRD) occurs in inherited prion diseases, specifically familial Creutzfeldt‐Jakob disease (p.E200K variant) and fatal familial insomnia (p.D178N variant), despite the theoretical 50% autosomal dominant inheritance risk.

Cortical thickness subtypes in cognitively unimpaired individuals: Differential network and transcriptomic vulnerability to cortical thinning

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION The emergence, stability, and contributing factors of Alzheimer's disease (AD) gray matter subtypes remain unclear. METHODS We analyzed data from 1323 individuals without a diagnosis of dementia (CDR < 1) with T1w‐MRI and amyloid‐PET, including 622 with longitudinal data (3.66 ± 1.78 years).

Multiple Antibody‐Coated Gold Nanoparticle‐Based ExoAssay for Rapid Isolation of CNS‐Specific Exosomes From Blood

Journal of Neurochemistry, Volume 169, Issue 10, October 2025.
A streamlined nanowire‐based approach (ExoAssay) enabled direct, rapid, and cost‐effective isolation of neuronal extracellular vesicles (EVs) from human plasma using multiple antibody‐coated magnetic nanowires. The isolated EVs were characterized using nanoparticle tracking analysis (NTA), immunoblotting, and transmission electron microscopy (TEM ...

Human and Mouse Alzheimer's Seeds Differentially Affect Amyloid Deposition and Microglia‐Dependent Plaque Response in Aged Mice

Aging Cell, Volume 24, Issue 8, August 2025.
This study shows that human and mouse brains contain a different pool of strains that differentially affect the formation of Aβ and tau aggregates. Moreover, the murine seeds trigger an unresponsiveness microglial state, which causes the loss of plaque microglial coverage and affects the formation of amyloid plaques, leading to more severe neuritic ...

White‐tailed deer habitat use and implications for chronic wasting disease transmission Uso del hábitat del ciervo de cola blanca e implicaciones para la transmisión de la caquexia crónica

Wildlife Monographs, Volume 217, Issue 1, July 2025.
White‐tailed deer habitat use, activity, and attraction to conspecifics is highly variable between sexes and seasons. In this study, we leverage an unprecedented dataset from Wisconsin to illustrate how deer respond to changing physiological and social needs through the course of year.

Emerging Roles of Biomolecular Condensates in Pre‐mRNA 3′ End Processing

WIREs RNA, Volume 16, Issue 4, July/August 2025.
Pre‐mRNA 3′ end processing factors can self‐assemble into biomolecular condensates that fine‐tune pre‐mRNA cleavage and polyadenylation, and their misregulation underlies disease. Nuclear speckles and histone locus bodies spatially compartmentalize distinct 3′ end reactions to ensure efficient gene expression control.
