Abstract
The aim of the present study was to find out if specific IgM (M) antibody (directed against rat kidney fraction 3 (rKF3)) or rKF3 antigen were able to influence disease progression in an experimental autoimmune kidney disease called slowly progressive Heymann nephritis (SPHN). The level of circulating autoantibodies (aabs) and the morphological and functional changes to the kidney were studied in six groups of rats. All of the treatment components (except post-treatment with M) used in the SPHN pre- and post-treated rats and post-treated-only rats had measurable beneficial effects (even during restimulation with the chemically modified renal antigen, 22 weeks after the induction of the disease) as demonstrated by diminished pathogenic IgG aab production, less severe kidney lesions, and proteinuria reductions. The injected rKF3 minimized progression best in this experiment, especially when administered in a pre- and post-treatment regimen. It is thought that the effect of rKF3 in the reduced progression of SPHN was due to increased production of specific IgM aabs, which in turn limited pathogenic aab production and continuous buildup of immune complexes in the glomeruli by facilitating removal or blockage of nephritogenic autoantigens from the circulation.

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
