Mesenchymal Stem Cell Membrane‐Camouflaged Liposomes for Biomimetic Delivery of Cyclosporine A for Hepatic Ischemia‐Reperfusion Injury Prevention
Hepatic ischemia‐reperfusion injury (HIRI) is a prevalent issue during liver resection and transplantation, with currently no cure or FDA‐approved therapy. A promising drug, Cyclosporin A (CsA), ameliorates HIRI by maintaining mitochondrial homeostasis but has systemic side effects due to its low bioavailability and high dosage requirements. This study introduces a biomimetic CsA delivery system that directly targets hepatic lesions using mesenchymal stem cell (MSC) membrane‐camouflaged liposomes. These hybrid nanovesicles (NVs), leveraging MSC‐derived proteins, demonstrate efficient inflammatory chemotaxis, transendothelial migration, and drug‐loading capacity. In a HIRI mouse model, the biomimetic NVs accumulated at liver injury sites entered hepatocytes, and significantly reduced liver damage and restore function using only one‐tenth of the CsA dose typically required. Proteomic analysis verifies the protection mechanism, which includes reactive oxygen species inhibition, preservation of mitochondrial integrity, and reduced cellular apoptosis, suggesting potential for this biomimetic strategy in HIRI intervention.
