Effects of ileum terminal antibiotic infusion (ITAI) on the mRNA expression of genes related to TLRs, cytokines and barrier function in the jejunal and colonic mucosa of growing pigs. Values are means ± SEMs (n = 6). Asterisks indicate statistically significant difference from control: *P < 0.05, **P < 0.01. TLR2 = toll-like receptor 2; TLR4 = toll-like receptor 4; TLR5 = toll-like receptor 5; IL-8 = interleukin-8; IL-10 = interleukin-10; IFN-γ = interferon-γ; TNF-α = tumor necrosis factor-α; ZO-1 = zonula occludens-1; MUC1 = mucin-1; MUC2 = mucin-2; OCLN = occludin
