The role of viruses in the pathogenesis of hypersensitivity pneumonitis
Bibliographic record
Abstract
Hypersensitivity pneumonitis (HP) is a worldwide lung disease caused by an immune response to a variety of mostly organic inhaled antigens. Only a small percentage (for example, 3 in 1000 dairy farmers) of subjects exposed to HP antigens develop the disease. It is possible that cofactors are needed to render the patient hypersensitive to environmental antigens; recent studies suggest that a viral infection could be such a trigger factor. Mice infected once with Sendai virus and simultaneously sensitized with HP antigens develop an enhanced response to the antigen that persists long after the transient viral infection has waned. Moreover, viral antigens were found in the lavage cells and lung tissue of patients with HP. Viral infections are known modulators of the immune response; viruses increase the antigen-presenting capacity of alveolar macrophages, decrease phagocytosis and antigen clearance, induce the release of pro-inflammatory cytokines, and favor the proliferation of Th1 T-lymphocytes (cells putatively associated with HP).

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.
