[Research progress of mouse model of hepatitis B virus infection].

Hepatitis B virus (HBV) infection is a global health problem. Animal models are important for the study of the HBV infection mechanism. In the study related to the mouse model of HBV infection, the researchers have established a variety of mouse models, including transgenic, plasmid hydrodynamic injection, virus vector transfection, cccDNA cycle simulation, human and mouse liver chimerism, and liver/immune dual humanization, according to the characteristics of HBV infection. Herein, the research progress of these models is summarized. Notably, the application of these models can further clarify the mechanism of HBV infection under the conditions of a specific immune response in vivo and lay the foundation for the development of new antiviral drugs and immunotherapy for HBV infection.
