| 描述信息 | The mechanisms underlying the natural control of hepatitis B virus (HBV) infection have long been an intriguing question. Given the wide physiological range of liver stiffness and the growing attention to the role of mechanical microenvironment in homeostasis and diseases, we investigated how extracellular matrix stiffness impacts HBV replication. High matrix stiffness significantly inhibited HBV replication and activated YAP, a key molecule in mechanosignaling. YAP activation notably suppressed HBV transcription and antigen expression, as confirmed in mouse models with elevated liver stiffness or YAP transduction. Several YAP-induced genes exhibited strong anti-HBV effects. In liver tissue from HBV-infected immune-tolerant and immune-active individuals, single-cell analysis revealed a significant negative correlation between YAP signature activation and HBV transcript levels. These findings unveil a novel mechanism that involves the mechanical environment of hepatocytes and YAP to control and clear viral infection in the liver, providing new perspectives for HBV cure studies and antiviral development. | ||||||||
