MYD88 and infection: In the case of infection with L. europaeus/GI.1 and GI.2 genotypes, upregulation of miR-155 was accompanied by decreased levels of MyD88 (17.5-fold reduction vs. control, p = 0.01 and 32-fold reduction vs. control, p < 0.001, respectively; Figure 1B) and p65 (11.5-fold reduction vs. control, p < 0.001 and 5.7-fold reduction vs. control, p < 0.001, respectively; Figure 1D).
