Differential Expression of CC Chemokines and the CCR5 Receptor in the Pancreas Is Associated with Progression to Type I Diabetes
Bibliographic record
Abstract
We investigated the biological role of CC chemokines in the Th1-mediated pathogenesis of spontaneous type I diabetes in nonobese diabetic (NOD) mice. Whereas an elevated ratio of macrophage inflammatory protein-1alpha (MIP-1alpha):MIP-1beta in the pancreas correlated with destructive insulitis and progression to diabetes in NOD mice, a decreased intrapancreatic MIP-1alpha:MIP-1beta ratio was observed in nonobese diabetes-resistant (NOR) mice. IL-4 treatment, which prevents diabetes in NOD mice by polarizing intraislet Th2 responses, decreased CCR5 expression in islets and potentiated a high ratio of MIP-1beta and monocyte chemotactic protein-1 (MCP-1): MIP-1alpha in the pancreas. Furthermore, NOD.MIP-1alpha-/- mice exhibited reduced destructive insulitis and were protected from diabetes. Neutralization of MIP-1alpha with specific Abs following transfer of diabetogenic T cells delayed the onset of diabetes in NOD.Scid recipients. These studies illustrate that the temporal expression of certain CC chemokines, particularly MIP-1alpha, and the CCR5 chemokine receptor in the pancreas is associated with the development of insulitis and spontaneous type I diabetes.

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.
