Cholesterol in mRNA-Lipid Nanoparticles can be Replaced with the Synthetic Mycobacterial Monomycoloyl Glycerol Analogue MMG-1
Messenger RNA (mRNA) vaccines based on lipid nanoparticles (LNPs) are stabilized with cholesterol, which is thought to be a critical LNP component because it is essential for membrane integrity and endosomal escape. Here, it is shown that cholesterol in LNPs can be replaced with an immunopotentiating lipid, i.e., a synthetic analogue of the C-type lectin receptor agonist monomycoloyl glycerol (MMG
