Kaplan-Meier survival plots for wild-type (WT), Rab27aash/ash (ashen), and Munc13-4 jinx/jinx (jinx) mice. Mice were challenged with a single intraperitoneal injection of LPS (7 mg/kg [A] or 12 mg/kg [B]). Survival curves were generated from two independent experiments with a total of 12 Rab27aash/ash, 12 Munc13-4jinx/jinx, and 18 wild-type mice. The difference in survival between the wild-type and Rab27aash/ash mice was significant (**, P = 0.0012) by the log-rank test. Although less significant, the difference in survival between wild-type and Munc13-4jinx/jinx mice was also evident (*, P = 0.05).
