Lipid nanoparticles optimized for large RNA cargo and tissue targeting enhance in vivo genome editing
Key Takeaways
  • A 384-lipid combinatorial screen using a 5.7 kb reporter mRNA identified LC-1 as a large-cargo-optimized ionizable lipid.
  • LC-1 LNPs achieved up to 79% Cas9 knockout in liver and 48% and 27% editing in brain and lung respectively.
  • Mechanistic analysis showed LC-1 maintains ordered fusogenic structure and stronger lipid–RNA interactions as mRNA size increases.
