Molecular mechanisms of HBeAg in persistent HBV infection

Purpose The aim of this study is to investigate the T-lymphocyte subpopulation and expression of programmed cell death-1 (PD-1), toll-like receptor (TLR)3, TLR4, and interferon (INF)-γ to illustrate the relationship between hepatitis B e antigen (HBeAg) and persistent hepatitis B virus (HBV) infection.
