Figure 1. Schematic of the mechanism of action of the CpG-PBNP-PTT-based nanoimmunotherapy in the TH-MYCN model of neuroblastoma (NB).
The CpG-PBNP-PTT-based nanoimmunotherapy mediates tumor cell priming along with immunogenic cell death (ICD) administered at a specific thermal dose, leading to T cell activation and generation of potent T cell memory, which can elicit long-term, tumor-free survival, and rejection of tumor rechallenge in a TH-MYCN model of NB. Further, the nanoimmunotherapy generates a potent abscopal effect, which slowers the progression of distal, untreated tumors enhancing the survival in the TH-MYCN NB model.
