This simple 3-amino acid trick boosts mRNA therapy 20-fold

A trio of common amino acids may hold the key to unlocking far more powerful gene therapies. Researchers found that adding them to lipid nanoparticles can boost mRNA delivery up to 20-fold and push CRISPR editing efficiency close to 90%. The trick isn’t changing the drug—but helping cells take it in more easily. In early tests, the approach dramatically improved survival and treatment outcomes, pointing to a simple but game-changing upgrade for future medicine.
