<i>In vitro</i>neutralization of prions with PrP<sup>Sc</sup>-specific antibodies
Bibliographic record
Abstract
Prion diseases reflect the misfolding of a self-protein (PrP(C)) into an infectious, pathological isomer (PrP(Sc)). By targeting epitopes uniquely exposed by misfolding, our group developed PrP(Sc)-specific vaccines to 3 disease specific epitopes (DSEs). Here, antibodies induced by individual DSE vaccines are evaluated for their capacity to neutralize prions in vitro. For both purified antibodies and immunoreactive sera, the PrP(Sc)-specific antibodies were equally effective in neutralizing prions. Further, there was no significant increase in neutralizing activity when multiple DSEs were targeted within an assay. At a low antibody concentration, the PrP(Sc)-specific antibodies matched the neutralization achieved by an antibody that may act via both PrP(C) and PrP(Sc). At higher doses, however, this pan-specific antibody was more effective, potentially due to a combined deactivation of PrP(Sc) and depletion of PrP(C).

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.
