Engineered exosomes conferred with ROS-regulation and immuno-suppression for ameliorating lupus nephritis.
Article in Journal of nanobiotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Mesenchymal stromal cell-derived exosomes (MEXs) possess inherent homing capabilities, tissue repair abilities, and anti-inflammatory and immunomodulatory functions, making them a promising alternative for treating lupus nephritis (LN). In this study, we present an innovative engineered MEX that serves both as a reactive oxygen species (ROS) scavenger and a rapamycin carrier for targeted LN therapy. The nanohybrid (CEX@Rapa) was developed by chemically conjugating ceria (Ce) nanoparticles to rapamycin-loaded thiol-functionalized MEXs through a Michael addition reaction. The resulting nanohybrids demonstrate minimal toxicity, optimal drug loading efficiency, superior cellular uptake capability, and remarkable anti-oxidant, anti-damage, and anti-inflammatory properties. Upon systemic administration to MRL/lpr mice, these nanohybrids tend to accumulate and persist at the site of kidney inflammation, mitigating the excessive immune response and promoting kidney repair, leading to significant alleviation of LN symptoms through the independent and synergistic effects of MEXs, Ce nanoparticles, and rapamycin. Therefore, we believe that Ce-immobilized MEXs, as an enhanced drug nanocarrier with ROS-regulating and immunomodulatory capabilities, hold substantial promise for treating LN and other autoimmune diseases.
