<b>Pivotal role of duct epithelia in salivary gland </b><b>GVHD </b>
Bibliographic record
Abstract
Although salivary glands are one of the target organs in graft-versus host disease (GVHD), mechanism of disease-related tissue injury has been poorly understood. To investigate it, we employed rat GVHD model including irradiation and donor cell transfer. Immunostaining revealed that submandibular and parotid, but not sublingual glands showed acinar reduction whereas ducts were almost intact. Ductal area of sublingual glands was significantly smaller than those of submandibular and parotid glands. Ductal epithelial cells upregulated expression of class II major histocompatibility complex antigens overtime. This expression preceded donor cell infiltration. Donor cell infiltration was preferentially found in ductal area at the early phase of the disease. While ductal epithelial cells exhibited upregulated mRNA expression of Th1-type chemokines, infiltrating donor cells exhibited their receptors CXCR3 and CCR5. These results suggest ductal epithelial cells have a pivotal role in the progression of GVHD.

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.
