Identification of tumor-specific mutations, called neoantigens, offers new exciting opportunities for personalized cancer immunotherapy. However, it remains challenging to achieve robust induction of neoantigen-specific T cells and drive their infiltration into the tumor microenvironment (TME). Here, we have developed a novel polyethyleneimine (PEI)-based personalized vaccine platform carrying neoantigen peptides and CpG adjuvants in a compact nanoparticle (NP) for their spatio-temporally concerted delivery.
