Immunomodulatory spherical nucleic acids

Abstract

We show that by organizing immunomodulatory nucleic acids into spherical nucleic acid (SNA) form, significant increases in activity are observed. Treatment of mice with cancer using immunostimulatory SNAs and nonalcoholic steatohepatitis (NASH) using immunoregulatory SNAs leads to improved disease outcomes vs. their unstructured counterparts. These improvements derive from several key SNA properties, including rapid cellular uptake, endosomal delivery, and multivalent binding. Overall, this work underscores the importance of the spatial orientation and presentation of oligonucleotides in the design of novel immunomodulators.
