Infant intestinal Enterococcus faecalis down-regulates inflammatory responses in human intestinal cell lines

Figure 4 IL-8 secretion in HCT116 upon bacteria with carbohydrates oxidation and protein digestion. A: IL-8 concentrations obtained in HCT116 from treatments using bacteria with oxidized cell wall carbohydrates; B: IL-8 concentrations obtained in HCT116 from treatments using chymotrypsin- and trypsin-digested bacterial cell wall proteins in buffer B. Experiments were repeated three times independently. Standard deviations were indicated as error bars.
