Abstract: The present disclosure is generally directed to spherical nucleic acids (SNAs) comprising multiple TLR agonists that enable the simultaneous activation of multiple TLR pathways for maximally synergistic immune activation. In some aspects, the present disclosure provides a spherical nucleic acid (SNA) comprising: (a) a nanoparticle core; (b) one or more toll-like receptor 3 (TLR3) agonists encapsulated in the nanoparticle core; and (c) a shell of oligonucleotides attached to the external surface of the nanoparticle core, the shell of oligonucleotides comprising one or more toll-like receptor 9 (TLR9) agonist oligonucleotides. Methods of using the SNAs are also provided herein.

Abstract: The present disclosure is directed to spherical nucleic acids (SNAs) comprising a nanoparticle core and an oligonucleotide shell attached to the external surface of the nanoparticle core, wherein the oligonucleotide shell comprises a mixture of class A CpG oligonucleotides and class B CpG oligonucleotides. The disclosure also provides methods of using the SNAs for, e.g., regulation of an immune response and gene regulation.
