However, magnetic hyperthermia in malignant melanomas with poor immunogenicity and an immunosuppressive microenvironment remains challenging. Here, all-in-one magnetic nanoparticles (αPD-L1/CpG@MCL) are developed for thermo-immunotherapy that enables hyperthermia with magnetic nanoparticles and immunotherapy with anti-PD-L1 antibody and CpG to improve the immunosuppressive tumor microenvironment. Magnetic hyperthermia with magnetite cationic liposomes (MCL, without anti-PD-L1 antibody and CpG) inhibits tumor growth in B16F10 melanoma; however, complete tumor regression is not observed. In contrast, complete tumor regression is observed when mice are treated with thermo-immunotherapy using αPD-L1/CpG@MCL. Additionally, mice cured after magnetic hyperthermia with αPD-L1/CpG@MCL rejected rechallenge with B16F10 cells, and cytotoxicity assay using splenocytes from cured mice shows the induction of antitumor immunity against B16F10 cells. Analysis of tumor-infiltrating lymphocytes reveals that magnetic hyperthermia with αPD-L1/CpG@MCL increased CD8<sup>+</sup> T lymphocytes and M1-like macrophages, and decreased M2-like macrophages, indicating an improvement in the tumor microenvironment.

The synthesis and reporting of a novel small-molecule phenylboronic acid cross-linker ((N(BA)<sub>3</sub>)) with a precise molecular structure is conducted for the first time, and it is successfully utilized with polyvinyl alcohol (PVA) dopamine to prepare a hydrogel with infarct microenvironmental responsiveness and anti-oxidant.

Results from both in vitro and in vivo studies reveal that the hydrogel is engineered with programmed capabilities for anti-oxidation, reducing inflammation, promoting new blood vessel formation, and inhibiting fibrosis, thereby significantly enhancing heart function post-MI.

This study reports a dual-functional hafnium oxide nanoplatform that combines high-Z radiosensitization with Bcl-2 gene silencing for enhanced cancer radiotherapy.
