关键词: HSP70 immunotherapy microwave irradiation nitric oxide thermotherapy

摘要:
Thermotherapy can directly kill tumor cells whilst being accompanied by immune-enhancing effects. However, this immune-enhancing effect suffers from insufficient expression of immune response factors (e.g., heat shock protein 70, HSP70), resulting in no patient benefiting due to the recurrence of tumor cells after thermotherapy. Herein, a nanoengineered strategy of programmed upregulating of the immune response factors for amplifying synergistic therapy is explored. Metal-organic frameworks nanoamplifiers (teprenone/nitrocysteine@ZrMOF-NH2 @L-menthol@triphenylphosphine, GGA/CSNO@ZrMOF-NH2 -LM-TPP nanoamplifier, and GCZMT nanoamplifier) achieve excellent microwave (MW) thermal-immunotherapy by programmed induction of HSP70 expression. After intravenous administration, GCZMT nanoamplifiers target the mitochondria, and then release nitric oxide (NO) under MW irradiation. NO inhibits the growth of tumor cells by interfering with the energy supply of cells. Subsequently, under the combination of MW, NO, and GGA, HSP70 expression can be programmed upregulated, which can induce the response of cytotoxic CD4+ T cells and CD8+ T cells, and effectively activate antitumor immunotherapy. Hence, GCZMT nanoamplifier-mediated MW therapy can achieve a satisfactory therapeutic effect with the tumor inhibition of 97%. This research offers a distinctive insight into the exploitation of metal-organic frameworks nanoamplifiers for enhanced tumor therapy, which provides a new approach for highly effective cancer treatment.© 2022 Wiley-VCH GmbH.
