The differences in the zonulin levels were significant between cells treated with gliadin and cell

treated with gliadin and viable L.GG at 30 min, 60 min and 90 min (P < 0.05) (Figure 2). Figure 2 Zonulin release in Caco-2 monolayers exposed to gliadin (1 mg/ml) alone or in combination with viable learn more L.GG (10 8   CFU/ml), heat killed L.GG (L.GG-HK) and L.GG conditioned medium (L.GG-CM). All data represent the results of three different experiments

(mean ± SEM). For each time of treatment, data were analyzed by Kruskal-Wallis analysis of variance and Dunn’s Multiple Comparison Test. (*) P < 0.05 gliadin vs. gliadin + Viable L.GG. In order to calculate the differences in the zonulin release over the time of exposure to gliadin alone or in combination with viable L.GG, L.GG-HK and L.GG-CM at different times (ranging from 0 min to 6 h), the AUCs of zonulin were calculated. The AUC value was higher in the gliadin-treated Caco-2 cells (14.06 ± 0.54) compared to those in cells treated with gliadin and viable L.GG (9.86 ± 0.28), gliadin and L.GG-HK (11.20 ± 0.33) and gliadin and L.GG-CM (11.93 ± 0.45). The difference was significant (P = 0.02) between Caco-2 cells treated GSK126 in vivo with gliadin alone and cells treated with gliadin and viable L.GG. Effects of gliadin and L.GG treatments on the polyamine profile The effects of viable L.GG, L.GG-HK and L.GG-CM on the polyamine profile of Caco-2 cell line were studied (Table 2). The administration of viable L.GG and L.GG-HK, but not L.GG-CM, led to a decrease of the single and total polyamine contents. The decrease was significant (P < 0.05) for spermidine, spermine

and the total polyamine CB-839 ic50 content compared to untreated control cells.
