FIG. 6.
Groups of five mice were injected intravenously with 5 mg of E. coli LPS (055:B5)/kg of body weight. At 2, 4, and 6 h after LPS challenge, mice were bled by cardiac puncture and levels of IFN-γ (A), IL-18 (B), and IL-12p70 (C) in serum were measured by ELISA. Results are the means ± standard errors of the means (∗, significantly different from wild-type controls [P < 0.05]).
