Administration of Soft Matter Lipid-DNA Nanoparticle As the Immunostimulant via Multiple Routes of Injection in Vivo

We elucidated the proper routes for injecting lipid-DNA micelles formulated with an oligonucleotide immune adjuvant in naive and tumor-bearing mice. We report herein that after assessing six ways of administering an immunostimulatory nanoparticle (INP), several of the injection routes effectively induced dendritic cell-mediated immune-stimulation in vivo, making them amenable to cancer immunotherapies and vaccines using such DNA materials.
