- Biohub reported that adding methionine, arginine, and serine to lipid nanoparticles increased mRNA delivery up to 20‑fold.
- Science Translational Medicine published the study on April 20, 2026, showing CRISPR editing efficiency rose from ~25% to nearly 90% after a single dose.
- Shana O. Kelley said any LNP formulation under development could benefit from the amino‑acid boost, implying broad impact across gene‑therapy pipelines.
Why it matters: Biotech firms developing mRNA and CRISPR therapies will see 20‑fold higher delivery and near‑90% editing, cutting doses and costs while speeding trials, lowering patient prices and expanding access.
