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 deposited from within the tumor cells. [\u2026] 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. 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. 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] 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] 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=”60px” responsive_lg=”hidden” responsive_md=”hidden”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"featured_media":0,"menu_order":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"wds_primary_resource_type":0,"wds_primary_data_type":0,"wds_primary_indication":0,"wds_primary_platform_type":0,"footnotes":""},"resource_type":[31],"data_type":[29],"indication":[],"platform_type":[36],"class_list":["post-1920","resource","type-resource","status-publish","hentry","resource_type-abstracts","data_type-pre-clinical","platform_type-nbtxr3"],"acf":[],"_links":{"self":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource\/1920","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource"}],"about":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/types\/resource"}],"version-history":[{"count":0,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource\/1920\/revisions"}],"wp:attachment":[{"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/media?parent=1920"}],"wp:term":[{"taxonomy":"resource_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/resource_type?post=1920"},{"taxonomy":"data_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/data_type?post=1920"},{"taxonomy":"indication","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/indication?post=1920"},{"taxonomy":"platform_type","embeddable":true,"href":"https:\/\/nanobiotix.com\/fr\/wp-json\/wp\/v2\/platform_type?post=1920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
