The Internalization Pathways of Liposomes, PLGA, and Magnetic Nanoparticles in Neutrophils.
Article in Biomedicines, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND/
objectivesNeutrophils are emerging as promising candidates for cell-based nanodrug delivery to tumors due to their unique biological properties. This study aims to investigate the mechanisms of nanoparticle internalization by neutrophils, specifically focusing on liposomes, poly(lactic-co-glycolic acid) (PLGA), and magnetite nanoparticles. Understanding these mechanisms could enhance the efficiency of neutrophil-based nanodrug delivery for cancer treatment.
methodsNeutrophils were isolated from the peripheral blood of mice bearing 4T1 mammary adenocarcinoma. Confocal microscopy, transmission electron microscopy, and flow cytometry were employed to evaluate the uptake of liposomes, PLGA, and magnetite nanoparticles by neutrophils. The effects of cultivation conditions, such as the presence or absence of plasma in the growth medium, were also examined. Additionally, the roles of immunoglobulins (IgG/IgM) and cell surface receptors (Fc and scavenger receptors) in nanoparticle internalization were explored.
resultsAll types of nanoparticles were successfully internalized by neutrophils, though the mechanisms of uptake varied. Plasma presence in the medium significantly influenced nanoparticle binding, particularly for PLGA nanoparticles. Internalization of PLGA nanoparticles was found to depend on the presence of IgG/IgM in the medium and Fc receptors on neutrophil surfaces, while scavenger receptors were not involved.
conclusionsUnderstanding the distinct endocytosis pathways for different nanoparticles can improve the efficacy of neutrophil loading with nanodrugs, potentially advancing the development of neutrophil-based cancer therapies. The findings underscore the importance of the extracellular environment in modulating nanoparticle uptake.
