The Role of Glycocalyx Diversity and Thickness for Nanoparticle Internalization in M1-/M2-like Macrophages.

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
Very small superparamagnetic iron oxide nanoparticles (VSOPs) show diagnostic value in multiple diseases as a promising MRI contrast agent. Macrophages predominantly ingest VSOPs, but the mechanism remains unclear. This study identifies differences in VSOP uptake between pro-inflammatory M1 and anti-inflammatory M2 macrophages and explores the role of the pericellular glycocalyx. Glycosaminoglycans (GAG) synthesis activities and the pericellular glycocalyx for M1/M2-like macrophages were assessed by RT-qPCR, Click-iT reaction, and WGA-FITC staining. The uptake of europium-VSOP and Synomag by the two subtypes was measured using Prussian blue staining, fluorescent microscopy, and magnetic particle spectroscopy. The findings revealed that M2-like macrophages had higher GAG synthesis activity, a thicker glycocalyx, and increased nanoparticle uptake compared to M1-like macrophages. Enzymatic glycocalyx degradation significantly decreased nanoparticle uptake. This study demonstrates a positive correlation between glycocalyx and nanoparticle uptake that could be exploited for imaging and targeted therapy, particularly in cancer, where macrophage subtypes play distinct roles.
