Abstract
Inheritance of the apolipoprotein (apoE) epsilon4 allele is a risk factor for developing Alzheimer's disease (AD). The purpose of the present study was to determine effects of apoE-isoforms on the transbilayer distribution of cholesterol in synaptic plasma membranes (SPM) using mice expressing human apoE3 and apoE4. Total SPM cholesterol levels did not differ among the wild-type and apoE3 and apoE4 knock-in mice. However, a striking difference was observed in the transbilayer distribution of SPM cholesterol. ApoE4 knock-in mice showed an approximately 2-fold increase in exofacial leaflet cholesterol compared with apoE3 knock-in mice and wild-type mice. The results of this study suggest that pathogenic effects of apoE4 on AD development could be closely linked to alteration of cholesterol distribution in SPM.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
