Serina presents POZ-lipid LNP data showing no immune response in rats, solving PEG antibody issue
--------------------------------------------------------------------------------

- POZ-lipid did not trigger IgM or IgG response after repeat dosing in rats in a vaccine format.
- PEG-lipid standard elicited a strong, boosted antibody response under same conditions.
- Anti-PEG antibodies linked to anaphylaxis in mRNA vaccines; POZ-lipid offers immune-silent alternative.
- Data presented at 4th LNP Formulation & Process Development Summit on April 15, 2025.
- Discovery could enable safer LNP formulations for gene therapy and RNA medicines.
