RNA‐Based Immunostimulatory Liposomal Spherical Nucleic Acids as Potent TLR7/8 Modulators

T cells. In addition to introducing the first IS-LSNAs consisting of RNA, these experiments show that one can facilitate an antigen-specific T cell response greater than that of free or cationic lipid-transfected RNA of the same sequence selective for TLR7/8. This work points toward the promise of using IS-LSNAs comprised of RNA as potent and highly tunable TLR-specific agents for the development of vaccines and other pharmaceuticals that require selective immunomodulation.
