The emergence of monkeypox has become a global health threat after the COVID-19 pandemic. Due to lack available specifically treatment against MPV, developing an vaccine is thus most prospective and urgent strategy. Herein, programmable macrophage vesicle based bionic self-adjuvanting (AM@AEvs-PB) first developed for defending virus (MPV). Based on MPV-related antigen-stimulated macrophage-derived vesicles, nanovaccine constructed by loading mature virion (MV)-related intracellular protein (A29L/M1R) simultaneously modifying with enveloped (EV) antigen (B6R), enabling them effectively promote presentation enhance adaptive immune through self-adjuvant Owing synergistic properties coloaded MV EV in defensing activation ratio antigen-presenting cells nearly four times than that single same dose, resulting stronger immunity host. Notably, intramuscular injection uptake AM@AEvs-PB demonstrated vigorous immune-protective effects mouse challenge attempt, offering promising strategy pre-clinical development.

Abstract High‐performance theranostic systems are of paramount importance for achieving precise image‐guided cancer immunotherapy. Here, a novel nanoplatform is presented that integrates aggregation‐induced emission luminogen (AIEgen) with prussian blue (PB) nanocatalyzer robust The AIEgen dimethylamine substitution demonstrates compelling near‐infrared (NIR) light‐induced photothermal conversion and photodynamic therapy (PDT) capabilities. By incorporating into porous PBNPs, further enveloped within M1 macrophage membrane, tumor‐specific nanoagent constructed. This strategic integration effectively constrains the molecular motion AIEgen, leading to amplified NIR‐II fluorescence brightness PDT attributes. Moreover, PBNPs can catalyze tumor‐overexpressed H 2 O generate oxygen boost efficacy, PB's NIR absorption also intensifies photoacoustic imaging effect. provides comprehensive information photoimmunotherapy in orthotopic breast cancer‐bearing mice.
