βCTF-Correlated Burst of Hippocampal TNFα Occurs at a Very Early, Pre-Plaque Stage in the TgCRND8 Mouse Model of Alzheimer's Disease
Bibliographic record
Abstract
Tumor necrosis factor-alpha (TNFα) regulates neuronal excitability. We investigated whether alterations in the level of TNFα occur at a time point that precedes the reported seizure-associated hyperexcitability of hippocampal networks in pre-plaque models of Alzheimer's disease (AD). Western blot and ELISA experiments indicated a significant increase in hippocampal TNFα expression in 1-month-old TgCRND8 mice that correlated with levels of the β-C-terminal fragment (βCTF) of amyloid-β protein precursor. CD11b labeling indicated changes in microglial morphology toward an activated state, suggesting that these cells may be a putative source of the observed TNFα increase during this pre-symptomatic stage of AD-like pathology.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
