Feed-based delivery of plasmid DNA using milk-derived extracellular vesicle-polyethylenimine complexes enables hepatic transgene expression in goldfish
Oral administration through feed offers a non-invasive, cost-effective, and scalable approach for gene delivery in aquaculture. However, gastrointestinal degradation and intestinal barriers severely limit the oral delivery of plasmid DNA (pDNA). In this study, we developed a ternary nanocarrier composed of bovine milk-derived extracellular vesicles (MEVs), polyethylenimine (PEI), and pDNA (MPPs)…
