found that RBC membrane‐camouflaged 2D MoSe2 nanosheets (RBC‐MoSe2)‐mediated PTT could obviously decrease M2‐related Arg1 and CD206 mRNA levels and increase tumor‐inhibiting M1‐related TNF‐α and iNOS2 mRNA levels.[190] Mechanically, the PTT could ablate tumors and then release tumor‐associated antigens, resulting in enhanced specific tumor antigen‐presentation and CD8+ T cell activation. Here, MRC1 is linked to neoplasm.
