Abstract

fetched live from OpenAlex

Abstract Stress may play a key role in alopecia areata (AA), though the exact interactions of stress with AA remain undefined. Corticotropin‐releasing hormone (CRH), the proximal regulator of the stress axis, has been recognized as an immunomodulatory factor in tissues and peripheral blood mononuclear cells (PBMCs). We used multicolour flow cytometry to identify receptor CRHR1 expression on PBMC subsets in AA patients ( n = 54) and controls ( n = 66). We found that CRHR1 was primarily expressed by circulating monocytes. CRHR1 expression on monocytes was enhanced in AA compared with controls (3.17% vs. 1.44%, p = 0.002, chi‐squared test). AA incidence was correlated to elevated CD14 + monocyte numbers ( R = 0.092, p = 0.036) and markedly independently correlated with increased CRHR1 expression ( R = 0.215, p = 0.027). High CRHR1 expression was significantly related to chronic AA (disease duration &gt;1 year; p = 0.003, chi‐squared test), and large lesion area (AA area &gt;25%; p = 0.049, chi‐squared test). We also observed enhanced percentages of active monocytes and reduced CD16 + CD3− NK cell numbers in AA patients' PBMCs ( p = 0.010; 0.025, respectively). In vitro CRH treatment of PBMCs and human monocyte cell line THP‐1 promoted CD86 upregulation. The findings imply that stress‐related factors CRH and CRHR1 contribute to AA development and progression where higher CRHR1 expression is associated with chronic AA and larger lesions.

Full frame distilled prediction

Teacher imitation

Not 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.
