Probiotic Leuconostoc mesenteroides ssp. cremoris and Streptococcus thermophilus induce IL-12 and IFN-γ production

Figure 3 Kinetics of cytokine mRNA expression in probiotic bacteria-induced human PBMC (pooled samples from four donors), 10 bacteria/cell, 10 &mgr;g RNA/lane on 10 g/L agarose gel and Northern blot analysis with indicated cDNA probes was carried out. Ethidium bromide staining of gels was used to verify equal loading of RNA. See Figure 1 for abbreviations of bacteria. A: S. pyogenes, L. rhamnosus GG or S. thermophilus and B: B. breve, L. mesenteroides, P. freudenreichii.
