The local effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) on the inflammatory atheroma: beyond LDL cholesterol lowering
Bibliographic record
Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9) has gained extensive attention since the discovery of its role in mediating hepatic low-density lipoprotein (LDL)-receptor (LDLR) degradation, and therefore regulating plasma LDL cholesterol clearance. However, emerging studies have indicated that PCSK9 may have pleiotropic effects on the development of atherosclerosis and eventually cardiac dysfunction by mechanisms independent of the regulation of LDL cholesterol levels. In this review, we will discuss recent findings of how PCSK9 affects cellular responses and the pro-inflammatory microenvironment within the local atherosclerotic vascular wall, which are critical for atherosclerotic plaque progression. We will also discuss recent research on the potential direct effects of PCSK9 on cardiomyocyte viability and function. These pathways may be critical for understanding the mechanisms of PCSK9’s cardioprotective effects beyond LDL cholesterol lowering.

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.
