Defect‐Engineered BiO2‐X Nanosheets Mediate Sono‐Thermomechanical ECM Remodeling for Hepatocellular Carcinoma Immunotherapy

Advanced Science, EarlyView.
Herein, an ultrasound‐responsive BiO2‐X/siFn1 nanoplatform is developed to overcome anti‐PD‐1 resistance in hepatocellular carcinoma. Upon ultrasound irradiation, the platform downregulates fibronectin expression, while its sonothermal effect softens the dense extracellular matrix and activates antitumor immunity in the tumor microenvironment, thereby ...

Spatiotemporally Controlled Sequential Chemo‐Immunotherapy Activates Pyroptosis for Robust Anti‐Tumor Immunotherapy

Advanced Science, EarlyView.
A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

Bacterial backpacks for targeted delivery of piezoelectric nanoparticles to enhance sonodynamic immunotherapy

BMEMat, EarlyView.
Leveraging bacterial hypoxia targeting, KBTO NPs accumulate at the tumor site. Under the ultrasound irradiation, KBTO NPs produce reactive oxygen species to kill tumor cells and eliminate bacteria, preventing overgrowth and inflammation. The lysed bacteria act as antigens to trigger antitumor immunity and further enhanced by the immune checkpoint ...
