Antigen-Driven Evolution of B Lymphocytes in Coronary Atherosclerotic Plaques
Bibliographic record
Abstract
Recent data indicated that adaptive immunity is involved in the process of atherogenesis. Oligoclonal recruitment of T lymphocytes has been described in coronary plaques of patients with acute coronary syndrome. However, the nature of immune response remains to be determined. In the present study, we examined the Ab response in six coronary plaques obtained by endoluminal directional atherectomy. The IgG1/kappa-coding gene repertoires of B lymphocytes present in circulating blood and in coronary plaques were cloned and analyzed. In all of the six plaques, we observed 1) a skewed usage of heavy and light IgG1/kappa Ab-coding genes, 2) an oligoclonal distribution of V(K), J(K), and V(H), D(H), and J(H) genes with overrepresentation of some rarely used IgG genes, and 3) the unequivocal signs of Ag-driven clonal expansion and evolution of B cells. The data document for the first time the presence of a local Ag-driven clonal evolution of B cells in human atherosclerotic plaques.

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.
