Improving the safety of lipid nanoparticle-based DNA delivery for extended gene expression

DNA delivery using lipid nanoparticles results in severe toxicity in mice. However, we find that the incorporation of endogenous anti-inflammatory lipids into the lipid nanoparticles mitigates this toxicity and enables prolonged gene expression.
