Roles of TLR4-TRIF and caspase-11 during C. rodentium infection in vivo. A, survival of WT, Tlr4−/−, Myd88−/−, Trif−/−, and Myd88−/−Trif−/− mice infected with 1 × 1010 C. rodentium by oral gavage. B and C, bacterial burden in fecal pellets of infected mice determined at day 7 after infection. D, working model for TLR4-/TRIF-mediated regulation of caspase-11 expression and noncanonical inflammasome activation in C. rodentium- and E. coli-infected macrophages.
