Prion Protein Strain Diversity and Disease Pathology
Bibliographic record
Abstract
The infectious agents, prions, are composed mainly of conformational isomers of the cellular prion protein (PrPc) in its abnormal accumulated scrapie forms (PrPSc). The distinct prion isolates or strains have been associated with different PrPSc prion protein conformations and patterns of glycosylation and are associated with disease progression and severity. In humans, sporadic Creutzfeldt-Jakob disease (sCJD) is the most common form and has been divided into six subtypes, based on PrPSc electrophoretic mobility and allelic variation at codon 129, among which sCJD MM1 and sCJD VV2 are the two most commonly occurring subtypes with known clinical manifestations. The strain-specific response of PrPSc suggests both the molecular classification and the pathogenesis of prion diseases along with posttranslational modification of PrP in humans and animals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
