Analysis of the interplay between hepatitis B virus-positive hepatocytes and Kupffer cells ex vivo using mice as a model.

Kupffer cells play critical roles in both hepatitis B virus (HBV) persistence and clearance. Here, we provide a protocol for studying the interplay between Kupffer cells and HBV-positive hepatocytes ex vivo using mice as a model. This protocol includes hydrodynamic injection of HBV DNA into mouse hepatocytes, liver perfusion for isolating hepatocytes and Kupffer cells, and Seahorse metabolic analysis of Kupffer cells. This protocol allows the detailed analysis of how HBV-positive hepatocytes and Kupffer cells impact each other ex vivo. For complete details on the use and execution of this protocol, please refer to Li et al. (2022).
