abstract = {Reactive oxygen species (ROS)-mediated immunogenic cell
death (ICD) is crucial in radioimmunotherapy by boosting
innate antitumor immunity. However, the hypoxic tumor
microenvironment (TME) often impedes ROS production,
limiting the efficacy of radiotherapy. To tackle this
challenge, a combination therapy involving radiotherapy and
immune checkpoint blockade (ICB) with anti-programmed
death-ligand 1 (PD-L1) has been explored to enhance
antitumor effects and reprogram the immunosuppressive TME.
Here, we introduce a novel PD-L1 aptamer-functionalized
nanoradiosensitizer designed to augment radiotherapy by
increasing X-ray deposition specifically at the tumor site.
This innovative X-ray-activated nanoradiosensitizer,
comprising gold-MnO2 nanoflowers, efficiently enhances ROS
generation under single low-dose radiation and repolarizes
M2-like macrophages, thereby boosting antitumor immunity.
Additionally, the ICB inhibitor BMS-202 synergizes with the
PD-L1 aptamer-assisted nanoradiosensitizer to block the
PD-L1 receptor, promoting T cell activation. Furthermore,
this nanoradiosensitizer exhibits exceptional photothermal
conversion efficiency, amplifying the ICD effect. The
PD-L1-targeted nanoradiosensitizer effectively inhibits
primary tumor growth and eliminates distant tumors,
underscoring the potential of this strategy in optimizing
both radioimmunotherapy and photothermal therapy.},
