HDL Regulates TGFβ-Receptor Lipid Raft Partitioning, Restoring Contractile Features of Cholesterol-Loaded Vascular Smooth Muscle Cells.
Article in JACC. Basic to translational science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Many cells identified as macrophage-like in human and mouse atherosclerotic plaques are thought to be of vascular smooth muscle cell (VSMC) origin. We identified cholesterol-mediated down-regulation of TGFβ signaling in vitro in human (h)VSMCs by localization of TGFβ receptors in membrane lipid rafts, which was reversed by high-density lipoprotein (HDL)-mediated cholesterol efflux. This restored VSMC contractile marker (Acta2) and suppressed macrophage marker (CD68) expression by promoting TGFβ enhancement of Mir145 expression. In vivo, administration of ApoA1 (which forms HDL) to atherosclerotic mice also promoted VSMC Acta2 expression and reduced CD68 expression. Because macrophage-like VSMCs are thought to have adverse properties, our studies not only show mechanistically how cholesterol causes their transition, but also suggest that efflux-competent HDL particles may have a therapeutic role by restoring a more favorable phenotypic state of VSMCs in atherosclerotic plaques.
