Nuclear BCL10 in primary Sjögren’s syndrome
Bibliographic record
Abstract
BACKGROUND: The events following triggering of antigen receptors and subsequent activation of the transcription factor nuclear factor kappa B (NFkappaB) need to be carefully controlled to prevent abnormal immune responses. BCL10 links the antigen receptor to NFkappaB. The aim of this study was to determine the expression pattern of BCL10 and NFkappaB in minor salivary gland infiltrates of patients with primary Sjögren's syndrome (pSS). METHODS: Minor salivary glands from patients with primary SS (n = 17) and sicca controls (n = 4) were evaluated by single and double immunohistochemistry and immunofluorescence for confocal microscopy. BCL10 and NFkappaB-p65 expression were evaluated in the infiltrating lymphocytes. Ectopic germinal centers (GCs) were investigated by CD21. Tonsil, lymph node and lymphoma tissue were used as positive controls. RESULTS: BCL10 nuclear positive cells were observed in focal lymphocytic infiltrates in the investigated minor salivary glands and were not restricted to patients with ectopic GCs. By double-staining, some of the BCL10 nuclear positive cells were identified as B cells. There was, however, no constitutive activation of NFkappaB as depicted by the exclusive cytoplasmic expression of p65 in the infiltrating lymphocytes in the pSS. CONCLUSION: Nuclear expression of BCL10 in infiltrating lymphocytes was a common occurrence in pSS minor salivary glands indicating it as a possible marker of autoimmune induced chronic inflammation. There was, however, no constitutive activation of NFkappaB.

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.
