On the other hand, RT has also been reported to induce immunosuppressive responses. A new class of material with high electron density, hafnium oxide, was designed at the nanoscale (HfO2-NP) to efficiently absorb ionizing radiation and augment the radiation dose<br \/>\ndeposited from within the tumor cells. [\u2026]<\/p>\n<p><strong>Methods:<\/strong> The potential ability of HfO2-NP exposed to RT to transform tumors into immunologically active lesions was tested in vitro and in vivo. <em>In vitro<\/em>, the level of ICD markers was evaluated in a panel of human cancer cell lines, following cells treated or not with HfO2-NP and irradiated. <em>In vivo<\/em>, a vaccination assay was performed to evaluate the host immune responses in immunocompetent mice inoculated with murine CT26 cancer cells treated or not with HfO2-NP and irradiated with 6 Gy. [\u2026]<\/p>\n<p><strong>Results:<\/strong> Higher DAMPs levels (cell surface expression of calreticulin, extracellular adenosine triphosphate level and extracellular high-mobility group box 1 level) were observed in the tested cancer cells treated with HfO2-NP + RT when compared to cancer cells exposed to RT. [\u2026]<\/p>\n<p><strong>Conclusions:<\/strong> These results suggest an efficient cell killing (ability to generate ICD) with superior potential of HfO2-NP + RT to transform the tumor into an effective in situ vaccine when compared to RT. Moreover, HfO2-NP treatment generates a marked increase of immune cells infiltration in the tumors suggesting that it may convert immunologically \u201ccold\u201d tumor into \u201chot\u201d tumor and could be combined with immunotherapeutic agents across oncology.[\/az_box_icons][vc_empty_space height=\u00a0\u00bb60px\u00a0\u00bb responsive_lg=\u00a0\u00bbhidden\u00a0\u00bb responsive_md=\u00a0\u00bbhidden\u00a0\u00bb][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>Hafnium oxide, an electron-dense material, was designed at the nanoscale to increase the radiation dose deposited from within the cancer cells: \u201cHot spot\u201d of energy deposit where the nanoparticles are when exposed to radiation therapy (RT).
