Timing recombinant prion protein conversion as a measure of prion activity in chronic wasting disease
Bibliographic record
Abstract
Chronic Wasting Disease (CWD) is a fatal neurological disease affecting cervids caused by prions. Infected cervids shed the CWD prion in bodily fluids and excrement, contaminating the environment and creating an agricultural and ecological calamity. Preclinical antemortem CWD testing method is demanded by CWD risk management programs. In vitro PrP-conversion assays have been developed as potential tools for such an approach with increasing sensitivity for prion detection. However, no method has been routinely employed thus far. Timing recombinant-PrP conversion into amyloid fibrils, seeded by elk CWD prion, as a diagnostic method is presented herein. The assay, termed “RePLICA”, is at least as sensitive for detecting elk CWD in brain tissues as Tg(CerPrP-M132)1536+/- and Tg(CerPrP-E226)5037+/- mouse bioassay models. The assay performs within a period of 35 hours, is consistently reproducible, and functions on elk brain and tonsil tissues. There are indications RePLICA has the potential to titre CWD infectivity.

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.
