Saccharomyces cerevisiae decreases the MAP Kinase (ERK1/2, p38) phosphorylation in differentiated IPEC-1 cells.

Differentiated IPEC-1 cells were exposed for 30 and 60 min with ETEC (3×10⁷ CFU/well) in the presence and absence of Sc (3×10⁶ yeasts/well). Western blots for phospho-ERK1/2 (p-ERK1/2) and phospho-p38 (p-p38) were performed. Total ERK1/2 and total p38 are shown as loading controls and did not change with each condition over time. Data are presented as means ± SEM, (n = 3) and the different letters represent significant differences between the treatments (P<0.05). Results are representative of three independent experiments.
