University of Pennsylvania School of Medicine Aug 11 2025 Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of RNA delivery. Now, two new solutions can help alleviate inflammation while still getting RNA where it needs to be in the cell. One discovery found that inflammation could be reduced with the addition of a unique biodegradable lipid to the
