Hyperbranched Polylysine-Based Lipopolyplexes Enable Efficient mRNA Delivery With Long-Term Storage Stability.
A novel ternary lipopolyplex (LPP) platform of lipid/HBPL/mRNA LPPs by incorporating hyperbranched poly-L-lysine (HBPL) as a functional polymeric core that yields high transfection efficiency across multiple cell lines, significantly enhanced dendritic cell (DC) maturation, and superior biocompatibility over a commercial transfection reagent.
