flag Modified lipid nanoparticles deliver mRNA vaccines to lymph nodes more effectively, reducing liver accumulation.

flag Penn engineers have developed modified lipid nanoparticles that deliver mRNA vaccines more effectively to lymph nodes while reducing liver accumulation. flag In animal models, these aroLNPs maintained strong immune responses while delivering at least tenfold less mRNA to the liver than the Moderna vaccine formulation, potentially allowing for lower doses and fewer side effects. flag This technology could improve future mRNA therapies for cancer and autoimmune diseases.
