WebIn recent years, research has been conducted on delivery systems for CpG ODNs using nanoparticles (NPs). The advantages of NP-based delivery of CpG ODN include (1) it can protect CpG ODN from DNase, (2) it can retain CpG ODN inside the body for a long period of time, (3) it can improve the cellular uptake efficiency of CpG ODN, and (4) it can ... WebPEI-HA/CpG nanoparticles also induced enhanced local and systemic cellular immune responses. These immune responses did not decay over six months of observation postimmunization. PEI and CpG synergized these comprehensive immune responses. Thus, the PEI-HA/CpG nanoparticle is a potential cross-protective inﬂuenza vaccine candidate.
