Targeted mRNA Delivery Using Bispecific Antibody-Lipid Nanoparticle Complexes
Bispecific antibodies were used to bridge PEG motifs on LNPs and selected cellular surface markers without elaborate chemical conjugation. The platform enabled targeted mRNA delivery in cell models and transferrin-receptor-associated delivery in vivo. Researchers also measured endosomal responses at different antibody-loading ratios. Splenic enrichment supports further immune-cell targeting studies, but does not establish a clinical delivery solution.
