Abstract (original English)

Continued consumption of a high-calorie diet results in the excessive accumulation of lipids in visceral adipose tissue, thereby increasing the risk of nonalcoholic steatohepatitis (NASH). Herein, ginger-derived exosomes (G-Exos) loaded with berberine (G-Exos@B) to facilitate targeted delivery to the liver through the formation of GR-Exos@B via the coalescence of ursodeoxycholic acid (UDCA)-introduced liposomes (RAL) for effective NASH intervention are developed. The introduction of G-Exos significantly equipped GR-Exos@B to effectively overcome the multi-intestinal barrier, facilitating their exit from the cell in an intact form. Interestingly, the hepatic-targeting of RAL allowed GR-Exos to penetrate the liver more effectively than G-Exos, resulting in 2.39-fold greater accumulation in the liver. In vivo experiments revealed that dual ROS depletion by berberine and GR-Exos synergistically enhanced the therapeutic effect against inhibited oxidative stress and hepatocellular steatosis compared to GR-Exos. Additionally, the macrophage-targeting capability of G-Exos is leveraged to suppress the activation of hepatic NLRP3 inflammasome complexes, transitioning from an M1 pro-inflammatory to an M2 anti-inflammatory state, which helped diminish hepatic macrophage levels and subsequently reduce lipid accumulation. Meanwhile, GR-Exos@B improved insulin sensitivity primarily by strengt
