P3C treatment leads to the production of pro-inflammatory cytokines IL6 and tumor necrosis factor-α (TNF-α) in vivo with and without hepatitis B virus (HBV) replication. (A) C57BL/6 mice were treated once with 50 or 100 µg of Pam3CSK (P3C) or phosphate-buffered saline (PBS) subcutaneously administered at day 0. (B) C57BL/6 mice received hydrodynamic injection with plasmid pAAV-HBV1.2 4 days (D-4) before P3C treatment, followed by a single SC injection with 50 µg of P3C or PBS at day 0 (D0). The serum levels of the pro-inflammatory cytokines interleukin-6 and TNF-α were measured using specific ELISAs. Data were analyzed using an unpaired Student’s t test. Statistically significant differences between the groups are indicated as *P < 0.05 and **P < 0.01.
