Lipid Accumulation in CD11c-expressing Intimal Myeloid Cells Induces Chemokine Production Required for Leukocyte Recruitment to Early Atherosclerotic Lesions
Bibliographic record
Abstract
Monocyte recruitment promotes the accumulation of myeloid foam cells in early atherosclerotic plaques. However, initial foam cells form prior to increased monocyte recruitment in hypercholesterolemic Ldlr-/- mice. These initial foam cells are derived from myeloid cells residing in the normal intima, and express integrin alphaX (CD11c). The goal of this thesis was to assess the role of initial foam cells in atherogenesis. The approach was to delete these cells by diphtheria toxin-induced apoptosis in Ldlr-/- bone marrow chimeras. Depletion of CD11c+ leukocytes resulted in significant reductions of intimal lipid accumulation, monocyte recruitment, intimal chemokine expression, but not endothelial cell adhesion molecule expression, at 10 and 21 days of hypercholesterolemia. These data suggest that lipid uptake by resident intimal CD11c-expressing myeloid cells during the earliest stages of atherosclerosis promotes chemokine production that is required for increased monocyte recruitment.

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.
