Summary

Lipid nanoparticle (LNP) delivery systems were developed for the in vivo delivery of siRNAs to hepatocytes. Novel lipids were designed, synthesized, and incorporated into next-generation LNPs, yielding greatly improved in vivo potency. Further, the mechanisms by which LNPs mediate delivery of siRNA in vivo were elucidated
