Acute-phase CD4 responses were efficient in self-limited infections but undetectable in the coinfected patient with HBV persistence. CD8 responses were multispecific irrespective of the outcome of infection, but the CD8 repertoire associated with HBV persistence lacked the most dominant specificities detectable in self-limited infections. In conclusion, insufficient CD4 help and defective CD8 repertoire may play a role at the early stages of infection in influencing HBV persistence.展开更多
