Effect of eGFP K181 infection on colon barrier permeability in allogeneic skin transplantation mice. 1 × 105 PFU eGFP K181 were inoculated intranasally into allogeneic skin transplantation MyD88(−/−) and MyD88(+/+) BALB/c mice on day 14 posttransplantation. (A) A schematic representation of the assay indicating time points of transplantation and eGFP K181 infection. (B) MCMV infection in colon tissues was confirmed by immunofluorescence with positive eGFP (Scale bar: 50 μm); (C) MCMV DNA and (D) IE1 levels in colon tissues were measured by PCR and Western blot, respectively; (E) Body weight and (F) colon barrier permeability were measured; (G) Necrosis (blue arrow) and inflammatory cell infiltration (red arrow) of colon tissues at 5, 9, 14, or 21 d postinfection (Scale bar: 100 μm). Data are shown as the mean ± SD of six mice per group. * P < 0.05, *** P < 0.001 vs. Myd88(+/+)
