ABSTRACT
Quercetin (QU), a natural flavonoid with potent anti-inflammatory and antioxidant properties, holds promise in treating acute liver injury (ALI). Nonetheless, its limited solubility hampers its efficacy, and its systemic distribution lacks targeting, leading to off-target effects. To address these challenges, we developed macrophage membrane-coated quercetin-loaded PLGA nanoparticles (MVs-QU-NPs) for active ALI targeting. The resulting MVs-QU-NPs exhibited a spherical morphology with a clear core-shell structure. The average size and zeta potential were assessed as 141.70 ± 0.89 nm and -31.83 ± 0.76 mV, respectively. Further studies revealed sustained drug release characteristics from MVs-QU-NPs over a continuous period of 24 h. Moreover, these MVs-QU-NPs demonstrated excellent biocompatibility when tested on normal liver cells. The results of biodistribution analysis in ALI mice displayed the remarkable ALI-targeting ability of MVs-DiD-NPs, with the highest fluorescence intensity observed in liver tissue. This biomimetic approach combining macrophage membranes with nanoparticle delivery, holds great potential for targeted ALI treatment.
