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

Figure 3

IL-8 production in Caco-2 cells after TNF-α stimulation. (a) Time course of response. Caco-2 cells were stimulated with TNF-α (10 ng/mL) for various times as indicated. (b) Dose response. Caco-2 cells were stimulated with TNF-𝛼 at various concentrations as indicated. Unstimulated Caco-2 cells were used as controls. Values are presented as means ± SD (𝑛=3). ^∗𝑃<0.05, ^∗∗𝑃<0.01, compared with the control medium.
