2025
This video demonstrates an in vitro technique to detect hepatitis B virus (HBV) infection via a recombinant HBV reporter system. Upon infecting host cells, the recombinant viral genome expresses the luciferase reporter enzyme, which produces bioluminescence upon oxidizing its substrate — helping detect viral infection.

Transparent zebrafish embryos have proved useful model hosts to visualize and functionally study interactions between innate immune cells and intracellular bacterial pathogens, such as Salmonella typhimurium and Mycobacterium marinum. Micro-injection of bacteria and multi-color fluorescence imaging are essential techniques involved in the application of zebrafish embryo infection models.
FAQs
NTCP expression supplies the surface entry factor that HepG2 cells otherwise lack for this model. Viral particles can bind the engineered receptor, making entry into liver-derived cells experimentally accessible. This feature allows investigators to examine how receptor availability affects the earliest stage of HBV or HDV infection and provides a consistent basis for comparing experimental conditions.
Following receptor binding and cellular entry, the model supports analysis of intracellular viral replication and antigen production. These readouts extend the investigation beyond attachment, helping researchers evaluate whether infection proceeds within the hepatocyte-like system. Examining both replication and antigen production can therefore connect an entry event with measurable consequences of viral infection.
Controlled culture conditions make infection experiments more reproducible by limiting variation in the cellular environment during viral exposure and subsequent analysis. Greater consistency helps researchers compare host responses, viral replication, and antigen production across experiments. It also strengthens evaluation of antiviral compounds because differences in measured outcomes can be related more directly to the tested intervention.
Evidence of intracellular viral replication or antigen production indicates that the process has advanced beyond viral particles merely binding the cell surface. Those outcomes provide measurable signs of infection biology within the cells. In contrast, examining receptor interaction alone primarily addresses entry, so combining entry-related observations with intracellular readouts gives a broader assessment.
A general workflow begins with culturing HepG2 cells engineered to express NTCP, exposing them to HBV or HDV particles, and maintaining the cells under controlled conditions. Investigators then assess outcomes such as intracellular viral replication, antigen production, or host responses. This sequence links receptor-mediated exposure to measurable infection biology in a reproducible laboratory setting.
The model is useful when researchers need to test whether antiviral compounds alter infection-related outcomes in NTCP-expressing liver cells. Measurements such as viral replication or antigen production can provide evidence of compound-associated effects under controlled conditions. Because the system supports reproducible infection, it can help compare candidate interventions and investigate strategies aimed at preventing or treating chronic viral hepatitis.
Within immunology and infection research, the system connects viral entry with host responses in a liver-cell context. Investigators can use it to study virus-host interactions, characterize infection biology, and examine cellular responses following exposure to HBV or HDV. These findings support broader efforts to understand chronic viral hepatitis and develop approaches to prevent or treat it.
