Western blot analysis of IκB degradation on bovine intestinal epithelial (BIE) cells after challenge with heat-stable Enterotoxigenic Escherichia coli (ETEC) pathogen-associated molecular patterns (PAMPs). BIE cells were pre-treated with Lactobacillus casei OLL2768 or Pam3CSK4 for 48 hours and then stimulated with heat-stable ETEC PAMPs or LPS. Levels of the counter-regulatory factor IκBα were studied at the indicated times post-stimulation. Significantly different from time 0 *(P<0.05).
