IL-21 or IL-33 treatments induce clearance of established BPS persistence. Plasmids expressing murine IL-21 or IL-33 and empty vector control were injected into BPS HDI mice at 4 and 7 weeks post injection (w.p.i.) (arrows). Sera were collected at indicated time points and levels of IL-21 and IL-33 (a), HBsAg (b), HBsAb (c) and HBeAg (d) were analysed using ELISA. Group means and s.e.m. within group are presented with group sizes (n) indicated. Group positivity percentage data are also presented for HBsAg (b, right panel), HBsAb (c, right panel) and HBeAg (d, right panel). HBV DNA for each group were analysed using pooled serum in commercial quantitative assay (e). Dotted lines represent cut-off thresholds (a, bd, right panels) and lower limit of quantification (e) respectively. geq genome equivalents
