  • Publication number: 20230398076
    Abstract: A method of producing a lipid-encapsulated RNA nanoparticle, comprising the steps a) flowing an aqueous solution comprising an RNA through a 1st tube having an inner diameter (ID) of between about 0.1? and 0.132?; b) flowing an ethanol solution comprising lipids through a 2nd tube having an ID of between about 0.005? and 0.02? at one third the flow rate of the aqueous solution through the 1st tube, wherein the lipids comprise a cationic lipid; and c) mixing the ethanol solution with the aqueous solution by flowing the ethanol solution and the aqueous solution into a mixing module consisting of the 2nd tube perpendicularly joined to the 1st tube; wherein the mixing produces an output solution flowing in the 1st tube comprising a turbulent flow of the RNA and the lipids in between about 10% to 75% ethanol v/v, and wherein the lipid-encapsulated RNA nanoparticles have a bilayer structure.

  • Publication number: 20230149310
    Abstract: Nucleic acid immunization is achieved by delivering a nucleic acid (NA), e.g., a mRNA or a DNA, encapsulated within a lipid-NA nanoparticle. The NA encodes an immunogenic compound of interest. The lipid-NA nanoparticle is effective for in vivo delivery of NA to a vertebrate cell, including upon administration to a subject. The lipid-NA nanoparticle are incorporated in pharmaceutical compositions for immunizing subjects against various diseases.
