Theoretically, our immune system could detect and kill
cancer cells. Unfortunately, tumors are well armed to fight these
attacks. Despite modern cancer treatments, metastases and relapses
remain a major problem. Increasing anti-tumor immunity might now be
made possible, thanks to copper telluride nanoparticles that mimic
enzymes, especially under NIR-II light irradiation. This induces
oxidative stress in tumor cells, quashing their immunosuppressive
status and triggering inflammatory processes, as Chinese scientists
report in the journal Angewandte Chemie.
