Effect of interferon‐γ on hepatitis B viral antigen expression in primary hepatocyte culture

Interferon‐α has been shown recently to selectively enhance hepatocyte expression of HBsAg/pre‐S2 in chronic hepatitis B virus infection in a way that may enhance immune recognition. To determine the effect of interferon‐γ on hepatitis B virus antigen expression, hepatocytes isolated from patients with chronic hepatitis B virus infection were incubated in the absence or presence of interferon‐γ and viral antigen expression was assessed by both radioimmunoassay and immunocytochemistry using appropriate monoclonal antibodies.
