Dose response curve of the carbachol-induced jejunal smooth muscle cell contraction from control mice (○), infected mice at day 7 PI (•), and day 35 PI (□). Values are the means ± SE of 4–6 experiments. *Significant difference of the cells from infected mice at day 7 PI compared with cells from control mice at the same concentration (P < .005). +Significant difference of the cells from infected mice at day 35 PI compared with cells from control mice at the same concentration (P < .01).

Dose response curve of the carbachol-induced jejunal smooth muscle cell contraction from noninfected control (○), incubated with 10 ng/mL of IL-4 (•), and 10 ng/mL of IL-13 (■). Values are the means ± SE of 4–6 experiments. +Significant difference of the cells incubated with IL-4 compared with control cells at the same concentration (P < .05). *Significant difference of the cells incubated with IL-13 compared with control cells at the same concentration (P < .05).

5. Figure 4
(A) Semiquantitative TGF-β1 mRNA expression in muscle layer from noninfected control mice, infected mice at day 10, and day 28 PI. Values represent the means ± SE of TGF-β1 to G3PDH ratio from at least 3 mice. *Significant difference from correspondent noninfected controls (P < .05). (B) TGF-β1 protein quantification by ELISA in muscle layer from noninfected control mice, infected mice at day 7 and day 35 PI. The results are expressed as concentration of picograms of TGF-β1-protein per milliliter of sample solution. Values represent the means ± SE from at least 5 mice. *Significant difference from correspondent noninfected controls (P < .05).

6. Figure 5
TGF-β1 protein quantification by ELISA in primary cultured muscle cells from control, incubated with 100 ng/mL of IL-4 and 100 ng/mL of IL-13. The results are expressed as concentration of picograms of TGF-β1 protein per milliliter of sample solution. Values represent the means ± SE from at least 3 mice. *Significant difference from correspondent nonincubated controls (P < .01).

(A) COX-2 protein expression by Western blot in primary cultured muscle cells from control (lane A), incubated with 100 ng/mL IL-4 (lane B), 100 ng/mL IL-13 (lane C), or 100 ng/mL TGF-β1 for 16 hours (lane D). Each lane was loaded with 30 μg protein. These blots are representative of similar results obtained at least 3 times. (B) PGE2 protein quantification by ELISA in primary cultured muscle cells from control, incubated with 100 ng/mL IL-4, 100 ng/mL IL-13, and 100 ng/mL TGF-β1. The results are expressed as concentration of picograms of PGE2-protein per milliliter of sample solution. Values represent the means ± SE from at least 3 mice. *Significant difference from correspondent nonincubated controls (P < .05).
