Homozygous NF-kB1 mutation causing combined immunodeficiency: a histopathological analysis
Bibliographic record
Abstract
Introduction: The nuclear factor-kB (NF-kB) signaling pathway plays a major role in mediating multiple cellular processes, including immune and inflammatory responses. Aims: We describe the histopathological findings of lymph nodes from a patient with a homozygous NF-kB subunit 1 (NF-kB1) mutation causing a combined immunodeficiency phenotype. Results: A nodal biopsy was performed for lymphadenopathy evaluation, in the context of development of persistent EBV infection. Our findings show that this patient has normal lymph node tissue present, however, abnormal histopathology features were observed, including atrophic germinal centers. B cell subset components within the B cell domain were also analyzed. The development of the B cell response during EBV infection was found to be significantly impaired. Conclusion: Aberrant signaling due to NF-kB1 deficiency has a significant impact on the development of B cell immunoproliferative responses. Statement of novelty: We report on the abnormal histopathology findings of lymph node biopsy from a patient with homozygous NF-kB1 mutation.

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.
