Stimulation of AMCs withIL-1β failed to evoke characteristic TRIF-regulated genes, such asIfnb1, Irg1, Ifit2, andCxcl10[81], [143].Importantly, these genes were also absent from the datasets of Haddad etal.[19] andBollopragada et al.[84],suggesting that signaling through TLR3 and/or TLR4 is not prominent in intrauterinetissues following term labor, at least among the cases selected for these studieswhich showed no signs of chorioamnionitis. This evidence concerns the gene TLR4 and chorioamnionitis.
