Abstract: Provided is a host factor specific for hepatitis B virus (HBV) infection. The specific host factor CREBH can remarkably enhance HBV infection. The specific host factor can, on the one hand, enhance entry of HBV, and on the other hand, enhance transcription of HBV to some extent. In the CREBH regulatory pathway there is a specific host factor SCARF2. During HBV infection, an N-terminus EGF-like domain of SCARF2 plays a crucial role in the infection and entry of HBV. The two correlated specific host factors provide a new target for inhibiting HBV infection.
