WebObjective Hepatitis B virus (HBV)-specific T cells are main effector cells in the control of HBV infection and hepatitis B surface antigen (HBsAg) is suggested to be a critical factor in the impaired immune response, a hallmark of chronic HBV infection. In addition to HBsAg, other viral markers such as hepatitis B core-related antigen (HBcrAg) are available, but … WebSep 1, 2024 · Whereas 91 different antigen-specific CD8 + T-cell populations were identified across patient samples, HBV-specific CD8 + T cells were abundant in liver and HCC lesions. In samples from patients with underlying HBV infection ( n = 30/46), the presence of intrahepatic HBV-specific CD8 + T-cell populations correlated with …
