Autoimmunity and the pathogenesis of type 1 diabetes
Bibliographic record
Abstract
Type 1 diabetes mellitus (TID) is an autoimmune genetic disease with unidentified environmental agents affecting its pathogenesis. Susceptibility is determined by the interaction of MHC and non-MHC genes in the thymus, primarily by the IDDM1 locus, which is extremely polymorphic and thus generates multitudes of predisposing and protective haplotypes for binding self-peptides. By presenting these peptide antigens to immature T-cells for activation and selection, most autoreactive cells will be deleted, but inefficient presentation and subsequent deficiencies of non-MHC genes allow some cells to escape to the periphery and to be eliminated by anergy or regulatory T-cells. T-cell dysregulation to a Th1 response with secretion of inflammatory cytokines promotes a self-perpetuating autoimmune cascade leading to overt disease unless blocked by suppressive cytokines from Th2-type cells. Since autoantibodies reflect target-cell destruction, early insulin autoantibodies may be transient due to benign insulitis induced by insulin or proinsulin. Multiple autoantibodies denote epitope spreading to cryptic autoantigens, likely involving posttranslational variants. Thus, the resulting T1D development requires coordinated abnormal variations, and this requirement limits its occurrence to a small minority of susceptible individuals.

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.
