Abstract
Background: Allergic rhinitis is a major risk factor for asthma development. Lower airway inflammation and remodeling have been observed in allergic rhinitis subjects without asthma. Tissue repair processes involve the production of extracellular matrix, in which fibroblasts play a major role. These cells originate from bone marrow progenitors called fibrocytes. The number of fibrocytes is increased in asthmatics following allergen exposure. In allergic rhinitis, allergen-induced inflammation has been widely observed, but studies on allergen-induced lower airway remodeling are still limited. The aim of this study is to determine the effect of seasonal allergen exposure on the profile of fibrocytes isolated from blood of allergic rhinitis subjects without asthma. Methods: Non asthmatic subjects with seasonal allergic rhinitis were recruited. At baseline (out of the pollen season), medical history, skin prick tests, spirometry, methacholine bronchoprovocation, blood sampling and sputum induction were performed. At the peak of rhinitis symptoms, the tests were repeated. Fibrocytes number and level of activation were determined in whole blood. Cells were stained for fibrocyte markers (CD34, CD45, CXCR4, collagen I) and analyzed by flow cytometry. Results: Thirty subjects (18F:12M) aged 28 8 years were recruited. Among the 12 subjects that completed the study yet, there were 12.2 7.9 % of fibrocytes at baseline, whereas there were 7.1 3.6 % of fibrocytes during the pollen season. Mean fluorescence of CXCR4 was 1614 646 (arbitrary units) at baseline and 1805 770 during the pollen season.

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.
