Abstract

Virus infection is initiated by recognition and attachment of the virus to the cell surface. Despite the fact that this interaction determines the virus‐related pathogenesis, its molecular basis remained obscure for HBV. This process is mediated primarily by the viral envelope and the cellular receptors. HBV infection is not exceptional in this regard but its putative receptors have not been identified yet. The recent development of protocols to establish HBV susceptible cell lines and unique tools to measure HBV‐cell attachment at a single cell resolution set the stage for the study of HBV‐host cell interaction. These studies revealed that the QLDPAF epitope of the HBV surface antigen large protein (LHBsAg) plays a major role in this process. Quantitative measurements suggested the presence of a second player in this process and both act synergistically to improve cell attachment. As the step of virus‐cell attachment is potentially susceptible to specific inhibitors, understanding the molecular basis of virus‐cell attachment can be expected to have therapeutic impacts.

The strength of the cytotoxic T lymphocyte (CTL) response is believed to influence the final outcome of hepatitis B virus (HBV) infection. Among the different CTL epitopes so far identified, the sequence 18-27 of the HBV nucleocapsid antigen is widely recognized by CTL of HLA-A2-positive patients wi

## Abstract We have recently reported that the naturally occurring spliced variant of Hepatitis B virus protein, HBSP, displayed proapoptotic activity through its BH3 domain. To investigate whether the BH3 domain in HBSP interacted with Bcl‐2 family of proteins, HBSP and Bcl‐2 family of proteins we

## Abstract Like all viruses, hepatitis B virus (HBV) replication and pathogenesis depends on the critical interplay between viral and host factors. In this review, we will focus on the recent progress in understanding the virus–host interactions at the level of the infected cell. These interaction
