Understanding the role of transforming growth factor-β1 in intimal thickening after vascular injury
Bibliographic record
Abstract
Intimal thickening is the most important cause of in-stent restenosis. The pathology of intimal thickening is attributable to a local inflammatory response after vascular injury which results in the production of cytokines. Transforming growth factor-beta1 (TGF-beta1) is a profibrotic cytokine that is involved in the induction of intimal thickening. Up-regulation of TGF-beta1 after arterial injury results in the activation of various downstream pathways which stimulate the proliferation and migration of vascular smooth muscle cells, as well as the production of local extracellular matrix proteins. Recent evidence suggests that antagonizing TGF-beta1 activity with direct or indirect inhibitors may attenuate or prevent intimal thickening. Additionally, TGF-beta1 synthesis, activation and downstream regulation may also serve as significant sources of treatment. This review attempts to show the role of TGF-beta1 in the pathology of intimal thickening and underlines the importance of TGF-beta1 as a target for therapy.

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.
