IL-17A levels in BALB/c mouse PBMCs cultured with EBV DNA and a TLR3 inhibitor. PBMCs were cultured with EBV DNA (9 × 103 copies), EBV DNA plus the TLR3 inhibitor (10 μM), the TLR3 inhibitor (10 μM) alone, or Staphylococcus epidermidis DNA (1.7 pg). After a 24-h culture period, IL-17A levels were assessed in the culture medium by an ELISA. *, P < 0.05 compared to nontreated cells; **, P < 0.05 compared to EBV DNA-treated cells.
