Abstract

fetched live from OpenAlex

ABSTRACT Alzheimer's disease (AD) is a major neurodegenerative disorder that affects more than 55 million people, with an incidence that is projected to triple by 2050. Despite continuous advancements in the field, reliable treatment and early detection strategies remain elusive. Extracellular vesicles (EVs) play a major role in cellular communication throughout the body. In this study, we assessed the cargo of neuronal‐specific EVs for their potential as AD biomarkers. We isolated EVs released from iPSC‐derived excitatory glutamatergic neurons generated from eight AD patients (ADiNEVs) and six healthy controls (iNEVs). We performed RNA‐sequencing and identified significant differences in RNA cargo between ADiNEVs and iNEVs. Notably, fewer small nuclear RNAs (snRNAs) were found in ADiNEVs. RNA transcripts significantly more abundant in ADiNEVs included MT‐CO1, PRR32 and IGSF8 messenger RNAs. We also observed fewer XIST long noncoding RNAs and miR‐7‐5p microRNA content in ADiNEVs. These findings suggest that precision medicine approaches, such as characterising the content of EVs from a patient's own cells, could advance early detection and management of AD.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
