Lactobacilli Reduce Chemokine IL-8 Production in Response to TNF-α and Salmonella Challenge of Caco-2 Cells

Figure 5

Effect of lactobacilli on IL-8 production by Caco-2 cells before or after S. typhimurium infection. (a) Caco-2 cells were pretreated with S. typhimurium and then treated with lactobacilli; (b) Caco-2 cells were pretreated with lactobacilli and then treated with S. typhimurium. Values are presented as means ± SD (𝑛=3). ^∗𝑃<0.05, ^∗∗𝑃<0.01, compared with the positive control (only S. typhimurium-treated group). Ls: L. salivarius; Lp: L. plantarum; Lr: L. rhamnosus LGG.
