Resistance of IRAK2-deficient mice to LPS-induced septic shock.
A, age- and sex-matched wild type (n = 22) and
IRAK2-deficient (n = 21) mice were injected intraperitoneally with
LPS (20 mg/kg body weight). Survival was monitored for 7 days after LPS
challenge. B, concentrations of TNFα, IL1β, IL 6, and IL
10 were measured by enzyme-linked immunosorbent assay in sera from wild type
and IRAK2-deficient mice 0, 1.5, and 3.5 h after injection of LPS (4 mg/kg of
body weight). The results shown are the means ± S.D. of triplicate
determinations. *, p < 0.05.
