Radiotherapy can activate an in situ vaccine response and promote response to immune checkpoint inhibitors. Here the authors design a multifunctional nanoparticle to enhance tumor antigen presentation and modulate the tumor immune microenvironment following radiotherapy, showing improved anti-tumor immune responses in radiotherapy-treated tumors when combined with immune checkpoint inhibitors.
