(A) Effect of PPE concentrations on CXCL8 concentrations in the supernatant of Caco-2 cells stimulated by TNF and (B) in the supernatant of porcine colonic tissue stimulated by lipopolysaccharide (LPS). Supernatants were collected from Caco-2 cells, 24 h post-incubation and from porcine colonic tissues, 3 h post-incubation. Each data point represents n = 3, data presented as mean ± standard error; Dexa = Dexamethasone; *** p < 0.05 and ** p < 0.01 in comparison to control treatment group.
