Type 1 IFN‐induced protein MxA and plasmacytoid dendritic cells in lesions of morphea
Bibliographic record
Abstract
Morphea is an autoimmune sclerotic skin disease of unknown pathogenesis. As type 1 interferons (IFN) have been implicated in the pathogenesis of systemic sclerosis, we proposed that type 1 IFN promote localized inflammation and fibrosis in morphea. To investigate the expression of the type 1 IFN-inducible protein myxovirus A (MxA) and the presence of plasmacytoid dendritic cells (pDC) in lesions of morphea, lesional skin of 10 patients with morphea was examined by immunohistochemistry for the presence of the type 1 IFN-inducible protein, myxovirus A (MxA), and the pDC markers, CD123 and BDCA-2, and was compared with lesional skin of cutaneous lupus erythematosus, lichen planus and keloid. Lesional and non-lesional morphea skin was compared. MxA was expressed in the epidermis as well as the reticular dermis and subcutis in morphea. pDCs were abundant around vessels and between fibrous bundles. Non-lesional biopsies demonstrated little or no expression of MxA and pDC markers. Keloid showed minimal expression of MxA and pDC markers. We demonstrate the expression of type 1 IFN-related protein MxA and plasmacytoid DCs in lesional but not in non-lesional biopsies of morphea. These findings suggest a potential role for type 1 interferons in the pathogenesis of morphea.

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.
