Summary
Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an
important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral
replication. In hepatitis B infection, CD4+T Cells are the main effector cells in adaptive
immune response. This study was aimed at investigating the changes of CD4+T Cells frequency
and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside
analog(ue) therapy.Meanwhile, the investigators want to verify whether Peg IFN - alpha
suppressed the virus and the reduction of virus led to the recovery of CD4+T Cells function,
or Peg IFN - alpha enhanced CD4+T Cells function which gave rise to the decline of the virus.
