Defect‐Engineered BiO2‐X Nanosheets Mediate Sono‐Thermomechanical ECM Remodeling for Hepatocellular Carcinoma Immunotherapy
ABSTRACT Immune checkpoint blockade for hepatocellular carcinoma (HCC) is frequently limited by the extracellular matrix (ECM). Through transcriptomic profiling, we identify that acquired anti‐PD‐1 resistance in HCC models is closely associated with prominent Fibronectin 1 (Fn1) upregulation within the tumor microenvir...
