Comprehensive Evaluation of Human and Murine Protein Coronae Formed on Choline Carboxylic Acid Ionic Liquid-Modified PLGA Nanoparticles.
Article in Bioconjugate chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Despite decades of research, the successful clinical translation of intravenously administered nanomedicines is underwhelming. One significant barrier to progress is the opsonization and rapid clearance from the bloodstream due to protein corona formation as an innate immune response. Biocompatible nanoparticle coatings that act as a barrier between the nanomaterial and the physiological environment are being continuously explored to elevate delivery success. However, the formation and composition of protein coronae, especially across species, are still poorly understood, which hinders the progress of translation from preclinical animal models to human applications. Here, we use quantitative protein assays, LC-MS proteomics, and machine learning to catalog the protein coronae from human and mouse serum formed on poly(lactic-co-glygolic) acid (PLGA) nanoparticles and explore the impact of a large library of coatings comprised of cholinium fatty acid-based ionic liquids (ILs) from 4- to 10-carbon chains with varying degrees of unsaturation. We discover that the species matters, with vast changes in the coronae being observed, depending on the source of the serum sample. Additionally, even very small changes in the ionic liquid anion structure result in the formation of diverse hard coronae. We identify several ILs that show enriched dysopsonins and depleted opsonins relative to serum that are promising candidates for future development as therapeutics or in biosensing.
