The Effects of Pegylated Interferon and Nucleos(t)ide Analogues on Innate and Adaptive Immunity and Virological Control
Clinical effect | PegIFN | NUC |
---|---|---|
Innate immunity | Increase the production of IL-15 and expands NK cells (CD56bright NK), with upregulation of TRAIL and IFN-γ production | Reduce TRAIL-expressing CD56bright NK cells, with defective capacity to produce IFN-γ |
Adaptive immunity | Deplete CD8+ T cells amount and function | Restore HBV-specific CD8+ T-cell function after long-term treatment |
Overall effect | Suppress HBV replication and cccDNA transcription | Suppress HBV replication |
HBV DNA reduction | ++ | +++ |
HBeAg/HBsAg seroconversion | ++ | + |
PegIFN, pegylated interferon; NUC, nucleos(t)ide analogue; NK, natural killer; TRAIL, tumor necrosis factor-related apoptosis-inducing ligand; HBV, hepatitis B virus; cccDNA, covalently closed circular DNA; HBeAg, hepatitis B e antigen; HBsAg, hepatitis B surface antigen.
