Introduction: Acute lung injury (ALI) seriously threatens human health and is induced by multiple factors. When ALI occurs, lung lesions affect gas exchange and may trigger respiratory failure. Current clinical treatments are limited, and traditional drug delivery has drawbacks. Berberine, a natural drug with anti-inflammatory effects, has difficulty in effectively exerting its efficacy. Methods: The study designed a nano-micelle. Hydrophobic berberine was encapsulated with diselenide bonds as the linker. Then, lung epithelial cell membranes were extracted to encapsulate and disguise the nano-micelle. These nanoparticles were injected intravenously. Thanks to the cell membrane's specificity, they could bind to lung tissue, achieving targeted lung delivery. In the inflamed area of acute lung injury, the significantly increased reactive oxygen species level was used to break the diselenide bonds, enabling precise berberine release at the lung injury site. Results: The nano-drug (MM-NPs) was successfully prepared, with the encapsulation efficiency of berberine in the micelles reaching 68.2%. In a ROS environment, the nano-micelles could quickly release over 80% of berberine. In inflammatory MLE-12 cells, MM-NPs responded well to ROS, and cellular inflammatory factor levels were significantly improved after treatment. In a lipopolysaccharide (LPS)-induced pneumonia mouse model, MM-NPs achieved lung targeting. Further studies showed that MM-NPs administration significantly allevia...
