Zonulin release in Caco-2 monolayers exposed to gliadin (1 mg/ml) alone or in combination with viable 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.
